Abstract
OBJECTIVES Increasing evidence indicates that the thickness of periodontal soft tissues plays an important role in various clinical scenarios, thus pointing to the need of further clinical research in this area. Aim of the present study was to assess gingival thickness at the mandibular incisors by translucency judgement with two different probes and to validate if these methods are comparable and applicable as diagnostic tools. MATERIALS AND METHODS A total of 200 participants were included; gingival tissue thickness was measured by judging probe translucency at both central mandibular incisors, mid-facially on the buccal aspect of each tooth using a standard periodontal probe and a set of color-coded probe, each with a different color at the tip, i.e. Colorvue Biotype Probe (CBP). Frequencies and relative frequencies were calculated for probe visibility. Agreement between the standard periodontal probe and the CBP was evaluated via the kappa statistic. RESULTS When the periodontal probe was visible, the frequency of CBP being visible was very high. Kappa statistic for the agreement between the standard periodontal probe and the CBP was 0.198 (71.5% agreement; p-value < 0.001) for tooth 41 and 0.311 (74.0% agreement; p-value < 0.001) for tooth 31, indicating a positive association of the two methods. CONCLUSIONS An agreement that reached 74% was estimated between the standard periodontal probe and the color-coded probe at central mandibular incisors. CLINICAL RELEVANCE: In the context of the present study, the two methods of evaluating gingival thickness seem to produce comparable measurements with a substantial agreement. However, in the 1/4 of the cases, the visibility of the color-coded probe could not assist in the categorization of the gingival phenotype.

Abstract
BACKGROUND The primary purpose of this two-arm, parallel design, randomized controlled study is to compare healing of the palatal tissue donor site when platelet-rich fibrin (PRF) is used as a wound dressing compared to the use of a hemostatic agent. Secondary outcomes of patient pain perception and analgesic intake were also evaluated. METHODS Seventy-four patients receiving free gingival grafts were randomized to receive either PRF (test) or hemostatic agent (control) as a palatal wound dressing by patients selecting a sealed envelope containing their group assignment (initially 37 envelopes for PRF group and 37 for hemostatic agent group). Patient pain assessment and analgesic consumption were documented using a 21-point numerical scale (NMRS-21) at 24, 48, and 72 hours post-surgery. At 1-, 2-, 3-, and 4-week follow-up appointments palatal early healing index (PEHI) scores including wound color, epithelialization, presence or absence of swelling, granulation tissue, and bleeding on gentle palpation were generated by direct intraoral examination by a blinded examiner unaware of the patients' treatment group. RESULTS NMRS-21 pain scores showed a significant reduction in pain over time in both groups, with no significant difference between groups at any time point. No significant between-group difference was found in the amount of analgesics taken by patients at 24, 48, and 72 hours. There was significant improvement in PEHI scores over the 4-week time period in both groups, but there was no significant difference in PEHI score at each time point (1, 2, 3, 4 weeks) between groups. CONCLUSIONS: Study findings suggest that there is no difference in early palatal wound healing, patient pain perception, or analgesic consumption between use of PRF or a hemostatic agent as donor-site wound dressings.

Abstract
BACKGROUND Attached gingival phenotype has a crucial impact on the implant's durability and its future success. PURPOSE This study aims to measure and compare buccal peri-implant gingival thickness following grafting with connective tissue graft (CTG) and the concentrated growth factor (CGF) graft. STUDY DESIGN, SETTING, SAMPLE This is a split-mouth designed randomized controlled clinical study in which a total of 20 aged 18 to 55 have bilateral missing teeth in the maxillary premolar region with less than 2 mm of healthy peri-implant gingival thickness. Patients were excluded if they were smokers, had poor oral hygiene, had uncontrolled widespread periodontal disease, or had a history of radiation treatment. The same surgical protocol was followed for each study participant, where an independent blinded medical practitioner assigned the first stage side to be treated with CTG, while the second stage side with CGF 2 weeks later. EXPOSURE VARIABLE The primary exposure variable of this study was the gingival grafting technique; CTG or CGF. OUTCOME VARIABLE The primary outcome variable was the buccal peri-implant gingival thickness. Gingival thickness was measured at six different times; immediately before the procedure (T0), after 30 days (T1), after 45 days (T2), after 3 months (T3), after 6 months (T4), and after 12 months (T5). COVARIATES The covariates were age, sex general health, and periodontal status. ANALYSIS The statistical analysis; repeated measures analysis of variance test was used to compare the gingival thickness between the studied follow-up times within each group. The level of significance was set at ≤ 0.05. RESULTS The sample was composed of 40 treatment sites of 20 patients. The mean age of the sample was 32 years and 45% were male. The mean gingival thickness value of the CTG group was 1.62 mm with a (standard deviation = 0.18) compared to 1.28 mm for the CGF group with (standard deviation = 0.20) and an overall P value (0.001) at T5. CONCLUSIONS AND RELEVANCE CTG showed to have better gingival thickness than CGF in managing peri-implant buccal gingival thickness deficiency.

Abstract
AIM This clinical case study is to highlight the improvement of periodontal health of mandibular canines using a soft tissue alternative of fish origin, a piscine graft. METHODS A 37-year-old female patient was referred to a periodontal practice for evaluation of mucogingival deformities around teeth #22 and #27 that were also diagnosed with recession, lack of keratinized tissue (KT), and bilateral high frenum attachment. Multiple soft tissue treatment options were presented to the patient, including autogenous, allograft, or xenograftporcine or piscine. RESULTS Given the patient's dietary preference, piscine option was preferred. The procedures were completed one at a time, first #22 and later #27, using the standard of care procedures for correcting mucogingival deformities using soft tissue alternatives. Post-surgical visits were scheduled at regular intervals (2, 4, 12, 24, 52 weeks) to evaluate the clinical outcomes. Healing was uneventful and clinical outcomes reveal correction of the mucogingival deformities. The amount of KT at the 52 weeks healing time, measured using an intraoral scanner was 2.12 mm on #22 and 1.78 mm on #27. CONCLUSION Within this clinical case's scope, piscine xenograft demonstrates to be a safe and effective soft tissue alternative to correct mucogingival deformities, increasing the KT width and achieving recession coverage. In addition, integration of patient's preference may lead to increased case acceptance and patient compliance. KEY POINTS What new information is this case providing? The use of a soft tissue alternative of piscine origin that was selected based on the patient's preference to correct bilateral combined mucogingival deformities (recession, lack of KT, and aberrant frenum attachment) around teeth. What is a key step to integrating this soft tissue alternative in clinical practice? The pre-hydration of the soft tissue alternative is preferred, compared to other soft tissue alternatives that might not require hydration (xenograft bovine origin). What are the limitations to success in this case? Confirming with the patient no pre-existing fish allergies.

Abstract
PURPOSE To measure the gingival phenotype-related features, gingival thickness (GT) and gingival width (GW), in healthy children and to investigate their association between them, with age, gender, tooth-type and arch. METHODS The gingival sites of 1029 teeth were included from 64 children (36 males and 28 females), with primary and mixed dentition, attending the paediatric dental clinic of Aristotle University, Thessaloniki. GT and GW were measured ultrasonically and with a periodontal probe, respectively. Mixed effects linear regression models were used to evaluate the association of gingival thickness and gingival width with the under-investigation parameters. Spearman's correlation coefficient was used to evaluate correlation between GT and GW. RESULTS Significantly thicker gingiva is found in posterior teeth compared to anterior teeth, in permanent teeth versus primary teeth and in maxillary teeth in comparison to mandibular teeth (p value < 0.001). Regarding GW, significantly wider gingiva is noted in posterior regions (p value = 0.022) and the maxilla (p value < 0.001). Gender-wise and concerning age GT and GW are not significantly affected. A weak and positive correlation between GT and GW is noted (rho 0.30, p < 0.001). CONCLUSIONS GT and GW present significant associations with arch and tooth-type. Findings from this study fulfil the further understanding of GT and GW of paediatric patients that are investigated sparsely throughout the literature and demonstrate an accurate, painless and simple method to map the gingiva.

Long-term stability of gingival margin and periodontal soft-tissue phenotype achieved after mucogingival therapy: A systematic review. J Clin Periodontol 2024; 51:177-195. [PMID: 37963451 DOI: 10.1111/jcpe.13900] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Revised: 10/12/2023] [Accepted: 10/23/2023] [Indexed: 11/16/2023]
Abstract
BACKGROUND The aim of this systematic review was two-fold: (i) to evaluate the long-term (≥5 years) stability of the gingival margin position, keratinized tissue width (KTW) and gingival thickness (GT) in sites that underwent root coverage (RC) or gingival augmentation (GA); and (ii) to assess the influence of different local variables on the long-term stability of dental and gingival tissues. MATERIALS AND METHODS Randomized controlled trials (RCTs) and non-RCTs reporting short-term (i.e., 6-12 months after baseline surgical intervention) and long-term (≥5 years) follow-up data after surgical treatment of adult patients presenting single or multiple mucogingival deformities, defined as sites presenting gingival recession defects (GRDs) and/or (KTW) deficiency (i.e., <2 mm), were considered eligible for inclusion. MEDLINE-PubMed, EMBASE and Cochrane Central Register of Controlled Trials databases were searched for articles published up to 15 May 2023. Mixed-effects multiple linear regression was used to assess the association between KTW, type of surgical procedure and time (i.e., independent variables) on the stability of the gingival margin in sites that received RC or GA therapy. RESULTS Of the 2569 potentially eligible records, 41 (reporting 40 studies) met the eligibility criteria. Graphical estimates including data from all RC procedures found an upward trend in recession depth (RD) increase over time. Conversely, it was observed that in 63.63% of RC studies and in 59.32% of RC treatment arms KTW increased over time, particularly in sites treated with subepithelial connective tissue grafts (SCTGs). Conversely, sites that underwent GA procedures generally exhibited an overall reduction of KTW over time. However, sites treated with free gingival grafts (FGGs) showed a decrease in RD after 10 years of follow-up. Three main findings derived from the pooled estimates were identified: (i) Gingival margin stability was associated with the amount of KTW present during short-term assessment (i.e. the greater the KTW at 6-12 months after treatment, the more stable the gingival margin). (ii) The use of autogenous soft-tissue grafts was associated with lower RD increase over time. (iii) Treatment approaches that contribute to the three-dimensional enhancement of the gingival phenotype, as clearly demonstrated by FGG, were associated with gingival margin stability. CONCLUSIONS The extent of apical migration of the gingival margin appears to be directly related to the amount of KTW and GT upon tissue maturation. Interventions involving the use of autogenous grafts, either SCTG or FGG, are associated with greater short-term KTW gain and lower RD increase over time.

Abstract
OBJECTIVES A digitally designed stent was invented to assist vestibuloplasty and free gingival graft (FGG) after jaw reconstruction. This study aimed to compare the effects of conventional soft-tissue management comprising vestibuloplasty combined with FGG and modified soft-tissue management using a digitally designed stent on the vestibular sulcus depth (VD), keratinised-tissue width (KTW) and peri-implant tissue health in patients undergoing jaw reconstruction. MATERIALS AND METHODS This prospective cohort study enrolled patients who underwent jaw reconstruction using a fibular flap, iliac flap, or onlay bone graft followed by implant-supported rehabilitation at the Peking University School and Hospital of Stomatology between May 2019 and July 2022. Patients in the stent group received digitally designed stents following vestibuloplasty combined with FGG for peri-implant soft-tissue management. Patients in the control group underwent a conventional vestibuloplasty combined with FGG. VD and KTW were evaluated immediately after implant loading (T2) and 1 year after implant loading (T3), and the atrophy rates of VD and KTW were calculated. Peri-implant clinical parameters were evaluated at T3. Comparisons between the groups were performed using the Mann-Whitney U test. The effects of age, sex, primary disease, reconstruction type, reconstructed jaw and the number and location of implants on VD and KTW were evaluated using linear regression analysis. RESULTS There were no significant differences in the atrophy rates of VD and KTW between the stent and control groups at T2 and T3 (both P ≥ 0.05). There were no significant differences in peri-implant clinical parameters between the stent and control groups at T3 (P ≥ 0.05). Reconstruction type, location of implants and primary disease influenced VD, and reconstruction type and age influenced KTW. CONCLUSIONS There was no significant difference in the maintenance of VD and KTW after jaw reconstruction between soft-tissue management using a digitally designed stent and the conventional method. Further, digitally designed stents do not affect peri-implant tissue health. CLINICAL RELEVANCE Digitally designed stents can simplify clinical procedures without adverse effects on peri-implant tissue health, but they do not promote keratinized mucosa augmentation and vestibuloplasty.

Abstract
BACKGROUND The purpose of this study is to determine if there is a difference in dimensional change of a free soft tissue autograft (FSTA) with epithelium compared to without epithelium. The secondary aim is to determine the patient and professional evaluation of color match and graft texture between the two groups. METHODS Patients with ≤2 mm keratinized tissue indicated for a FSTA were randomly assigned to control group (FSTA with epithelium) or test group (de-epithelialized FSTA). The vertical and horizontal measurements of the grafts were taken at surgery, and 1, 3, and 6 months postoperatively. Patients were asked to evaluate the color match at each postoperative time point on a 21-step Numeric Rating Scale (NRS-21). Professional assessment of color match and graft texture were evaluated on images at the same time points. RESULTS Forty-six patients and 55 grafts were included in the study. For change in graft height, width, and area, there were no significant differences between the treatment groups at any time point. Graft height and area in both groups decreased significantly from baseline to month 1 (p < .001), but no other difference was significant over time. When patients and professionals used the NRS-21 for evaluation of color match between the graft site and the surrounding soft tissue, there was no significant difference between the treatment groups. Similarly, evaluation of texture match on color images and black-and-white images revealed no significant differences between or within groups. CONCLUSION De-epithelialized FSTA showed no difference in dimensional change or color and texture match compared to FSTA with epithelium.

Abstract
OBJECTIVE This scoping review aimed to systematically identify evidence-based interventions to stimulate healing or protect the harvested palate of patients undergoing gingival grafting. MATERIAL AND METHODS The study followed guidelines from the Joanna Briggs Institute and PRISMA-ScR (protocol available at osf.io/zhafn). PubMed, Embase, and seven other databases were searched on November 2022, with additional monitoring until April 2023. The inclusion criteria focused on studies evaluating outcomes related to the donor area (palate) and interventions for healing or protecting it, regardless of publication year and language. Data from the included publications was extracted and presented through narrative text, tables, and figures. RESULTS Eighty-one studies (including 64 clinical trials, four case series, five theses, and eight systematic reviews) and 37 clinical trial records were included. The number of studies on this topic has significantly increased, reflecting a growing interest in the field. Thirty-six interventions with published results and 12 interventions with unpublished results from clinical trial registers were identified. Some promising interventions that showed potential for improving patient-reported outcomes include cyanoacrylate adhesive, platelet-rich fibrin (PRF), and the combination of palatal stents and healing agents. CONCLUSIONS Thirty-six interventions with published results were identified for postoperative use on the harvested palate, showing varying levels of evidence and conflicting effectiveness for specific outcomes. CLINICAL RELEVANCE Postoperative discomfort and pain in the palate are commonly experienced by patients undergoing grafting procedures using this region as the donor area. Awareness of the available options and their levels of evidence is crucial for informed decision-making.

Efficacy of free gingival grafting to augment keratinized mucosa around dental implants in posterior regions after restorative procedures: A retrospective clinical study. J Prosthet Dent 2023; 130:715-722. [PMID: 35000695 DOI: 10.1016/j.prosdent.2021.12.013] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2021] [Revised: 12/01/2021] [Accepted: 12/01/2021] [Indexed: 01/22/2023]
Abstract
STATEMENT OF PROBLEM Data on the shrinkage of free gingival grafts (FGGs) vary. Most studies have analyzed grafts in nonmolar sites because of measurement limitations and have addressed the changes in grafts and keratinized mucosa width (KMW) only in the early healing phase. PURPOSE The purpose of this retrospective clinical study was to assess the dimensional changes of an FGG in the posterior regions and their influencing factors, with the aim of obtaining sufficient and stable KMW after restoration. MATERIAL AND METHODS A total of 77 implants in 40 participants who had undergone an FGG surgery were recruited. Graft sizes during surgery and the surface areas of keratinized mucosa at the follow-up visit after restorations were compared by digital analysis and verified by clinical measurements and photographs. The association between shrinkage and the graft sizes, implant location, and sex and age of the participants was evaluated. The influence of the shrinkage of FGG on the KMW after restoration was analyzed by multivariable linear regression with generalized estimating equation (GEE) models. RESULTS The mean ±standard deviation shrinkage of FGG around implants in the posterior regions was 24.76 ±14.77%, and the mean ±standard deviation KMW was 4.16 ±1.77 mm at the follow-up visit. Larger grafts had a statistically higher shrinkage ratio (P<.001). No statistically significant difference was found regarding the effect of implant location, sex, and age on the shrinkage of FGG and final KMW (P>.05). The mean ±standard deviation follow-up period after restoration was 12.45 ±7.73 months CONCLUSIONS: Free gingival grafting was found to be a predictable treatment approach for augmentation of KMW around implants in the posterior region after the fabrication of prostheses as long as grafts of sufficient size were placed. Stable outcomes were shown in the study participants in the follow-up period of up to 3 years.

Abstract
BACKGROUND/OBJECTIVES To systematically review the available evidence concerning the risk factors for gingival recessions (GR) after orthodontic treatment (OT). DATA COLLECTION AND ANALYSIS Data was obtained and collected by systematically searching 3 data bases: Pubmed, EMBASE, and Web of Science until 20 April 2023. Controlled trials, cohort, case-control or cross-sectional studies describing GR or clinical crown height (CCH) after OT were included. The risk of bias in the selected studies was evaluated with the methodological index for non-randomized studies. RESULTS Forty-eight articles were included, investigating the following six risk factors for GR: 1. OT (n = 21), 2. Type of orthodontic intervention (n = 32), 3. Patient's baseline occlusal and skeletal characteristics (n = 14), 4. Mucogingival characteristics (n = 10), 5. Oral hygiene (n = 9), and 6. Others (n = 12). Significantly higher prevalence, severity and extent of GR were found in orthodontic patients by 10/15, 4/10, and 2/2 articles respectively. 10/16 articles reported significantly more GR and increased CCH in patients where orthodontic incisor proclination was performed. The evidence surrounding maxillary expansion and orthodontic retention was too heterogeneous to allow for? definitive conclusions. Pre-treatment angle classification, ANB, overjet, overbite, arch width and mandibular divergence were found not to be associated with GR (9/14), while pre-treatment crossbite, symphysis height and width were (5/7 studies). A thin gingival biotype, presence of previous GR, baseline width of keratinized gingiva and facial gingival margin thickness were correlated with increased risk of GR after OT by nine articles, while pocket depth was not. Oral hygiene, sex, treatment duration, and oral piercings were found not to be linked with GR in orthodontic patients, while GR was reported to increase with age in orthodontic patients by 50 per cent of the articles investigating this factor. The mean risk of bias for comparative and not comparative studies was 14.17/24 and 9.12/16. LIMITATIONS The selected studies were quite heterogeneous regarding study settings, variables reported and included very limited sample sizes. CONCLUSION Although studies regarding the risk factors for GR are relatively abundant, they are very heterogeneous concerning design, studied factors, methodology and reporting, which often leads to contradictory results. Uniform reporting guidelines are urgently needed for future research. PROSPERO REGISTRATION CRD42020181661. FUNDING This research received no funding.

Abstract
Covering: up to 2017-2022Many small molecule drugs are first discovered in nature, commonly the result of long ethnopharmacological use by people, and then characterized and purified from their biological sources. Traditional medicines are often more sustainable, but issues related to source consistency and efficacy present challenges. Modern medicine has focused solely on purified molecules, but evidence is mounting to support some of the more traditional uses of medicinal biologics. When is a more traditional delivery of a therapeutic appropriate and warranted? What studies are required to establish validity of a traditional medicine approach? Artemisia annua and A. afra are two related but unique medicinal plant species with long histories of ethnopharmacological use. A. annua produces the sesquiterpene lactone antimalarial drug, artemisinin, while A. afra produces at most, trace amounts of the compound. Both species also have an increasing repertoire of modern scientific and pharmacological data that make them ideal candidates for a case study. Here accumulated recent data on A. annua and A. afra are reviewed as a basis for establishing a decision tree for querying their therapeutic use, as well as that of other medicinal plant species.

Abstract
In this review, typical clinical complications involving periodontal tissues are illustrated that can be encountered in conjunction with orthodontic therapy (OT). Special considerations are given for various clinical scenarios, such as the patient presenting in periodontal health, with periodontitis, or with mucogingival conditions. While some of the complications are seen as common side effects of OT, other, more severe, problems that could have been avoided may be viewed as treatment errors. Recommendations are made on how to prevent these complications, based on the currently available evidence, on clinical practice guidelines, and on expert opinion. In conclusion, while there are several areas in which OT can have unwanted adverse effects on periodontal/mucogingival conditions, there is also great potential for synergies, offering opportunities for close cooperation between the two specialties (periodontics and orthodontics) for the benefit of patients affected by tooth malpositioning and/or periodontal or mucogingival problems.

Abstract
ABSTRACT: OBJECTIVES: Aim of this clinical study was to evaluate the effects on gingival thickness of three surgical techniques for root coverage: the coronally advanced flap (CAF) alone, with a sub-epithelial connective tissue graft (SCTG) or with leukocyte- and platelet-rich fibrin (L-PRF) membranes. METHODS Sixty patients with RT1 single maxillary gingival recession were treated with CAF + L-PRF (20 patients), CAF + SCTG (20 patients) or CAF alone (20 patients). At baseline and 6-month after treatment, gingival thickness (GT), keratinized tissue width (KT), gingival recession (GR), clinical attachment level (CAL), probing depth (PD), PROMs, and the aesthetic outcome were recorded. RESULTS CAF + SCTG and CAF + L-PRF groups showed a significantly greater mean GT increase than CAF alone (0.31 ± 0.10 mm) with no significant differences between CAF + SCTG (0.99 ± 0.02 mm) and CAF + L-PRF (0.92 ± 0.52 mm) groups (p = 0.55). CAF + SCTG was associated with a significantly greater KT gain (3.85 ± 1.04 mm), while in CAF + L-PRF (2.03 ± 0.53 mm) and CAF (1.50 ± 0.69 mm) groups, KT was not significantly increased. Both GR and CAL showed a significant within groups' improvement, without among-groups differences. No significant among-groups difference for the aesthetic outcome but greater discomfort and pain-killer consumption in CAF + SCTG group was detected. CONCLUSION All investigated surgical techniques produced significant GR reduction and CAL gain. GT was similarly augmented by CAF + L-PRF and CAF + SCTG techniques; however, the CAF + SCTG technique produced a more predictable KT and GT increase. CLINICAL RELEVANCE The results of our study suggest that the CAF + SCTG technique represents the most predictable method for the clinician to improve the gingival phenotype, an important factor for long term gingival margin stability.

Abstract
Among the complications of orthodontic treatment, mucogingival problems with gingival recession in the mandibular anterior teeth are challenging for clinicians. Mucogingival problems can lead to esthetic deficits, thermal hypersensitivity, tooth brushing pain, and complicated plaque control. Herein, we present a case of a 16-year-old female with gingival recession in the left mandibular central incisor after orthodontic treatment. The preoperative clinical findings showed a thin soft tissue biotype with root prominence in the mandibular anterior area. The interdental area was relatively depressed. After reflection of the full-thickness flap, root coverage using a bone graft substitute and subepithelial connective tissue graft obtained from the palatal mucosa was performed. The 6-month and 5-year postoperative clinical findings showed improved soft tissue phenotype. The cross-sectional CBCT scans 5 years after surgery showed a well-maintained labial bone plate in the mandibular incisors. Within the limitations of this case report, for patients with gingival recession in the mandibular incisors after orthodontic treatment, a successful biotype modification can be achieved with a combined procedure using subepithelial connective tissue graft with bone graft substitutes.

Abstract
AIMS To analyse the histological structure and histomorphometric characteristics of human hard palatal mucosa in order to determine the donor site of choice for connective tissue grafts from a histological point of view. MATERIALS AND METHODS Palatal mucosa samples from six cadaver heads were harvested at four sites: incisal, premolar, molar and tuberosity. Histological and immunohistochemical techniques were performed, as was histomorphometric analysis. RESULTS In the current study, we found that the density and size of cells were higher in the superficial papillary layer, whereas the thickness of the collagen bundles increased in the reticular layer. Excluding the epithelium, the mean percentage of lamina propria (LP) and submucosa (SM) was 37% and 63%, respectively (p < .001). LP thickness showed similar values in the incisal, premolar and molar regions, and a significantly greater thickness in tuberosity (p < .001). The thickness of SM increased from incisal to premolar and molar, disappearing in the tuberosity (p < .001). CONCLUSIONS As dense connective tissue of LP is the tissue of choice for connective tissue grafts, the best donor site from a histological point of view is tuberosity because it is composed only of a thick LP without the presence of a loose submucosal layer.

Abstract
INTRODUCTION Vestibuloplasty is a mucogingival procedure that aims to increase the vestibule and the amount of keratinized tissue (KT) around teeth and dental implants. Currently, the gold standard in this procedure is still represented by free gingival grafts (FGGs); however, they require a second surgical site, which means more morbidity for the patient and a higher risk of surgical complications, as well as surgical time and chromatic alteration of the recipient area. CASE PRESENTATION This is a description of the vestibuloplasty technique with platelet-rich fibrin (PRF) in a 35-year-old female patient with a thin gingival phenotype and no medical history of interest. The reason for consultation was tooth sensitivity during brushing and the presence of recessions in the fifth sextant. CONCLUSIONS The use of PRF as a graft biomaterial in vestibuloplasty is a valid and effective option as an alternative to secondary epithelialization of the surgical site, as well as to FGGs, with acceptable results in terms of KT gain and root coverage, and with minimal postoperative discomfort. KEY POINTS Why is this case new information? The use of PRF is an interesting option as an alternative to second-intention healing, as FGGs in vestibuloplasty. What are the keys to successful management of this case? The most important part of the membranes is the part that was in close relation to the erythrocyte fraction in the blood collection tube, so this part must be oriented toward the recipient bed. A minimum of four membranes should be obtained, overlapping one on top of the other. What are the primary limitations to success in this case? The stability of the PRF.

Abstract
Minimally invasive surgical procedures aim at optimal wound healing, a reduction of postoperative morbidity and, thus, at increased patient satisfaction. The present article reviews the concept of minimal invasiveness in gingival augmentation and root coverage procedures, and critically discusses the influencing factors, technical and nontechnical ones, and relates them to the underlying biological mechanisms. Furthermore, the corresponding outcomes of the respective procedures are assessed and evaluated in relation to a possible impact of a minimized surgical invasiveness on the clinical, aesthetic, and patient-related results.

Abstract
The purpose of this study was to compare the outcomes of a modified gingival graft technique, in which the released flap is positioned and sutured over the graft, with the conventional free gingival graft (FGG) procedure, when both are used for gingival augmentation. A 12-month, multicenter parallel randomized controlled trial was conducted. Subjects with buccal RT2 gingival recessions and keratinized tissue width (KTW) < 2 mm in at least one mandibular incisor were randomized to control group (n = 20; conventional FGG) or test group (n = 20; modified FGG; flap sutured over FGG using sling sutures). The primary outcome (KTW) was measured at baseline and after 3, 6 and 12 months, as was keratinized tissue thickness (KTT). Postoperative pain (POP) and analgesic intake were also recorded. Both techniques promoted a significant increase in KTW and KTT when compared to baseline (p < 0.05) with no significant differences between groups (KTW change of 6.1±1.5 mm and 5.4±1.6 mm, for control and test, respectively; p=0.16). However, test group patients reported less POP after 7 days and used less analgesic medication than control group patients (p < 0.05). We concluded that the modified FGG was comparable to conventional FGG in augmenting keratinized tissue width and thickness at mandibular incisors, but resulted in less patient morbidity.

Abstract
Background/purpose Clinicians use sedatives for anxiety patients at times in daily practice, but the direct influence of the medication on the wound healing of periodontal tissues is unknown. The aim of this study was to analyze the influence of the short-term administration of diazepam to patients with dental anxiety undergoing free gingival graft (FGG) procedures. Materials and methods A total of 51 FGG procedures in 39 patients were included. Twenty-six anxious patients medicated with 5 mg of diazepam from the night before surgery to 7 days after surgery served as the medication group, and the rest served as the control group. Direct examination, photographs and H2O2 were used to evaluate the healing of palatal wounds. Stress levels and sleep quality, and salivary melatonin levels were assessed. Results On Day 14, complete epithelization of the wounds was noted in 48.39% of the patients in the medication group and 35.29% of the patients in the control group. Regardless of whether they receive medication or not, groups with complete epithelialization by Day 14 had higher levels of preoperative melatonin than those without, with a P value of 0.02. The postoperative melatonin in the medication group tended to present higher levels than the control group. Conclusion Higher preoperative melatonin levels can accelerate wound healing. The short-term administration of the diazepam seemed to facilitate palatal wound healing by reducing stress and maintaining postoperative melatonin levels. This is the first time the relationships between sedatives, melatonin levels and palatal wound healing has been reported.

Abstract
BACKGROUND The aim of this study was to compare the effects of four different commonly used wound dressings in improving patient reported outcomes (PROMS) after free epithelialized mucosal grafts (FEGs) harvesting. METHODS Following 72 FEGs harvesting from 72 patients, patients were assigned into four groups. CONTROL collagen plug + sutures (CPS); test: collagen plug with cyano-acrylate (CPC), platelet rich fibrin (PRF) + sutures, or palatal stent only (PS). Patients were observed for 14 days, with evaluation of pain level utilizing the visual analog scale, number of analgesics consumed, need for additional analgesics, amount of swelling, amount of bleeding, activity tolerance, and willingness for retreatment. RESULTS Compared to the control group all test groups indicated significant lower pain perception (P < 0.0001), lower analgesic consumption (P < 0.0001), and higher willingness for retreatment (P < 0.0001), while no statistically significant differences among test groups were observed. There were no statistically significant differences in amount of day-by-day swelling, bleeding, and activity tolerance among four groups. Compared to other groups, the PS had the lowest overall pain scores (over the 14-day period). Palatal thickness, graft length, graft width, and graft thickness did not appear to affect patient morbidity (P > 0.05). CONCLUSIONS All interventions significantly decreased pain perception compared to a hemostatic collagen sponge alone over the palatal donor site after FEG surgery. In the first few days after surgery, the use of a palatal stent seemed to be associated with less overall pain, pain pills consumed, and higher willingness of doing the same procedure again.

Periodontal phenotype modification of complexes periodontal-orthodontic case scenarios: A clinical review on the applications of allogenous dermal matrix as an alternative to subepithelial connective tissue graft.

Abstract
OBJECTIVES The aim of this review is to address the potential applications of allogenous dermal matrix (ADM), as an alternative to subepithelial connective tissue graft (SCTG), in promoting periodontal phenotype modification (PPM) of challenging periodontal-orthodontic clinical scenarios. OVERVIEW The rationale behind the need of changing thin to thick gingival tissues is associated to the superior and more stable treatment outcomes promoted by PPM therapy. PPM, via soft tissue grafting, leads to clinical and histological changes of the pre-established original genetic conditions of the gingiva. Although SCTG-based procedures are recognized as the "gold standard" for the treatment of sites requiring root coverage and gingival augmentation, ADM has been recognized as the most suitable alternative to SCTG, particularly in clinical scenarios where the use of autogenous grafts is not possible. Thus, ADM is considered an optimal option for the treatment of patients with a history (or in need) of orthodontic tooth movement, due its two-fold potential indication: (1) the promotion of periodontal soft tissue phenotype modification; and (2) its use, as a barrier membrane, in hard tissues augmentation procedures. CONCLUSIONS ADM is a viable option for soft tissue augmentation, as well as for treatment approaches involving buccal bone gain. CLINICAL SIGNIFICANCE Periodontal phenotype modification therapy, when applied in challenging periodontal-orthodontic clinical scenarios, promotes root coverage and prevents the onset and development clinical attachment loss.

Abstract
Aims and Background:
Gingival phenotype has a crucial impact on the peri-implant marginal bone stability. The aim of this clinical trial is to assess and compare the efficacy of the sub-epithelial connective tissue graft (SCTG) and platelet-rich fibrin (PRF) in improving the peri-implant soft tissue phenotype and enhancing esthetic outcomes.
Materials and Methods:
The present study was a split-mouth randomized controlled clinical trial. A total of ten patients who had bilateral missing teeth in the maxillary esthetic zone with a thin gingival phenotype were included in this study. For each study participant, one randomly selected site was treated with SCTG, while the other was treated with PRF membrane during dental implant placement. Treatment outcomes included the assessment of the facial gingival thickness using cone-beam computed tomography (CBCT) at the baseline (T0) and 6 months postoperatively (T1), and the Pink esthetic score (PES) at T1 and 3 months later after prosthesis placement (T2).
Results and Discussion:
Both treatment options resulted in a significant increase in gingival tissue thickness at T1 compared with T0, and in PES at T2 compared with T1 (p ˂ 0.05).
Conclusion:
PRF is an effective alternative to SCTG in augmenting peri-implant soft tissue phenotype and improving esthetic outcomes. This would help overcome the complications associated with harvesting the SCTG and increasing patients’ satisfaction.

Abstract
INTRODUCTION In adult patients with thin phenotype, gingival recession is obvious in the mandibular incisors after a large amount of lingual tooth movement. A systematic review indicated that soft tissue augmentation before orthodontic treatment might yield satisfactory results with respect to the progression of gingival recession. However, the studies included had a low-to-moderate level of evidence. This study was designed to investigate the efficacy of soft tissue augmentation prior to orthodontic treatment on the prevention of gingival recession. METHOD AND ANALYSIS This is a single-centre, single-blind, randomised controlled, double-armed parallel group comparison trial. This study was initiated in December 2021 and end in December 2025 (anticipated). Patients with mild crowding in the lower arch and a thin gingival type was enrolled and randomly assigned in a 1:1 ratio to either group A (having soft tissue augmentation prior to orthodontic treatment) or group B (having orthodontic treatment only). The planned number of enrolled patients was 48 (24 patients × 2 groups). The primary endpoint was the mean change in recession of the gingival margin. Secondary endpoints included the probing depth, gingival phenotype, frequency of complete root coverage, gingival thickness, width of the keratinised gingiva, clinical attachment level, gingival recession class, full-mouth plaque score, alveolar bone thickness in the faciolingual dimension of the lower anterior teeth and lower incisor inclination. ETHICS AND DISSEMINATION The study protocol was approved by the Ethical Committee of the Shanghai Stomatological Hospital (certificate number (2021)016). The study was conducted in accordance with the Declaration of Helsinki, the Clinical Trials Act and other current legal regulations in China. Written informed consent was obtained from all the participants. The results of this study will be reported in journal publications. TRIAL REGISTRATION NUMBER ChiCTR2100050892.

Efficacy of biologics in root coverage and gingival augmentation therapy: An American Academy of Periodontology best evidence systematic review and network meta-analysis. J Periodontol 2022; 93:1771-1802. [PMID: 36279123 DOI: 10.1002/jper.22-0075] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2022] [Revised: 04/05/2022] [Accepted: 04/06/2022] [Indexed: 01/05/2023]
Abstract
BACKGROUND The aim of this systematic review was to assess the efficacy of three biologics, namely autologous blood-derived products (ABPs), enamel matrix derivatives (EMD) and recombinant human platelet-derived growth factor BB (rhPDGF-BB), in root coverage and gingival augmentation therapy. METHODS The protocol of this PRISMA 2020-compliant systematic review was registered in PROSPERO (CRD42021285917). After study selection, data of interest were extracted. A network meta-analysis (NMA) was conducted to assess the effect of different surgical interventions on the main clinical outcomes of interest (i.e., mean root coverage [MRC%], complete root coverage [CRC%], keratinized tissue width [KTW], gingival thickness [GT] change, and recession depth [RD] reduction). RESULTS A total of 48 trials reported in 55 articles were selected. All studies reported on the treatment of gingival recession defects for root coverage purposes. Forty-six treatment arms from 24 trials were included in the NMA. These arms consisted of treatment with coronally advanced flap (CAF) alone, EMD + CAF, platelet-rich fibrin (PRF) + CAF, and subepithelial connective tissue graft (SCTG) + CAF. Regarding MRC%, SCTG+CAF was associated with a significant higher estimate (13.41%, 95% CI [8.06-18.75], P < 0.01), while EMD+CAF (6.68%, 95% CI [-0.03 to 13.4], P = 0.061) and PRF+CAF (1.03%, 95% CI [-5.65 to 7.72], P = 0.71) failed to show statistically significant differences compared with CAF alone (control group) or with each other. Similarly, only SCTG+CAF led to a significantly higher CRC% (14.41%, 95% CI [4.21 to 24.61], P < 0.01), while treatment arms EMD + CAF (13.48%, 95% CI [-3.34 to 30.32], P = 0.11) and PRF+CAF (-0.91%, 95% CI [-15.38, 13.57], p = 0.81) did not show significant differences compared with CAF alone or with each other. Differences in the CI of PRF+CAF (symmetrical around a zero adjunctive effect) and EMD+CAF (non-symmetrical) suggest that EMD could have some additional value compared with PRF. Treatment with SCTG+CAF led to a statistically significant higher RD reduction (-0.39 mm, 95% CI [-0.55 to 0.22], P < 0.01), however EMD+CAF (-0.13 mm, 95% CI [-0.29 to 0.01], P = 0.08) and PRF+CAF (-0.06 mm, 95% CI [-0.23 to 0.09], P = 0.39) failed to show significant differences compared with CAF or with each other. While SCTG+CAF was associated with a statistically significant higher gain of KTW (0.71 mm, 95% CI [0.48 to 0.93], P < 0.01), EMD+CAF (0.24 mm, 95% CI [-0.02 to 0.51], P = 0.08) and PRF+CAF (0.08 mm, 95% CI [-0.23 to 0.41], P = 0.58) did not result into significant changes compared with CAF alone or with each other. Regarding the use of rhPDGF-BB+CAF, although available studies have reported equivalent results compared with SCTG+CAF, evidence is very limited. CONCLUSIONS The use of ABPs, EMD, or rhPDGF-BB in conjunction with a CAF for root coverage purposes is safe and generally promotes significant improvements respective to baseline clinical parameters. However, the adjunctive use of ABPs and EMD does not provide substantial additional improvements in terms of clinical outcomes and patient-reported outcome measures to those achieved using CAF alone, when baseline KTW is >2 mm. Both PRF+CAF and EMD+CAF rendered inferior MRC%, CRC%, RD reduction, and KTW gain compared with SCTG+CAF, which should still be considered the gold-standard in root coverage therapy. Although some studies have reported equivalent results for rhPDGF-BB+CAF compared with the gold-standard intervention, limited evidence precludes formal comparisons with CAF or SCTG+CAF that could be extrapolated to guide clinical practice.

Scheyer ET, Gomes P, Rossi A. The treatment of multiple gingival recession defects with connective tissue grafting and enamel matrix derivative in a private practice setting: Two case reports.

Abstract
BACKGROUND Dentofacial esthetics has become a mainstay treatment in periodontics. For a periodontal private practice to succeed in a referral-based environment, predictability and stability in treatment results are crucial. The scientific literature provides a guide to successfully treating multiple recession defects with non-carious cervical lesions and lingual recession. These case reports show how the use of biologic mediators, proper case selection, and proper surgical technique may provide a better treatment outcome for our patients. METHODS Two patients with multiple gingival recession defects were treated with autogenous tissue grafting in conjunction with the application of enamel matrix derivative (EMD) to attempt root coverage. Based on the Cairo classification, the recession defects were classified as type I in the maxillary buccal and lingual recession in the mandibular anterior. There were areas of no attached gingiva, loss of enamel, and the presence of non-carious cervical lesions. RESULTS At 3-month post-treatment in case #1 and 6-month post-treatment in case #2, satisfactory esthetic results for the patients and clinician were achieved. These short-term follow-ups were favorable for root coverage and soft tissue healing, especially at the 1-week visit. There was noticeably less edema and erythema. Additionally, dental hypersensitivity was no longer reported for both patients. CONCLUSION By using biologic mediators, such as an EMD combined with connective tissue grafting, both multiple recession defects with non-carious cervical lesions, and lingual recession cases, can be treated successfully in a private practice setting. Using an EMD provides no additional risks to patients, may result in faster healing, and would afford stability of long-term success by influencing true periodontal regeneration.

Abstract
Adequate alveolar bone volume is a prerequisite condition for successful orthodontic tooth movement and posttreatment stability. Mandibular anterior teeth are more likely to exhibit dehiscence and fenestration in adult patients, which make orthodontic treatment in adults challenging, especially when the amount of retraction of the anterior teeth is large. Herein, we report the treatment of augmented corticotomy only on the lingual side in the mandibular anterior region to increase the volume of soft and hard tissue assisting orthodontics in a Class I bialveolar protrusive malocclusion and propose management strategies of mandibular incisor retractions. A 22-year-old female with a chief complaint of protrusive mouth presented to the Department of Orthodontics for orthodontic treatment, diagnosed with Class I bialveolar protrusive. The orthodontic treatment plan involved the extraction of four premolars and extensive retraction of the anterior teeth using microimplant anchorage. In consideration of the fenestration and dehiscence in the mandibular anterior alveolar bone and the pattern of tooth movement, augmented corticotomy was performed on the lingual side combined with bone grafting. Clinical and radiographic evaluation after treatment revealed significant improvements in the facial profile and in periodontal phenotype. Augmented corticotomy assisting orthodontic treatment could be a promising treatment strategy for adult patients with alveolar protrusion to maintain periodontal health.

Abstract
Aim: The aim of this retrospective study was to evaluate the effectiveness of coronally advanced flap and connective tissue graft (CAF+CTG) in the treatment of gingival recessions (GR).Method: Periodontal records of 32 single and multiple GR in 11 patients treated with CAF+CTG were selected for the study. According to Cairo’s classification, recession type 1 defects were included. Recession depth (RD), probing depth (PD) and clinical attachment level (CAL) were assessed at baseline and follow-ups. Mean root coverage (MRC) and complete root coverage (CRC) were evaluated. Compliance with supportive periodontal therapy (SPT) was also determined.Results: Mean age of 11 patients was 29.6±4.4 years. The mean observation time of 32 recessions was 37.6±24.2 months. All clinical parameters showed an improvement between baseline and the latest follow-up. After treatment with CAF+CTG, MRC was 92.6±13.1% and CRC was achieved in 75% of the recessions. Compliance to SPT was calculated at 83.3%.Conclusion: The use of CAF+CTG yielded positive outcomes in terms of all clinical parameters and complete root coverage in Cairo recession type 1 defects with a mean observation period of >3 years. The results of the present study confirm the use of CAF+CTG as a gold standard for the treatment of gingival recessions.

Abstract
PURPOSE To analyze the tissue morphology around implant-supported prostheses by digital technology and to evaluate the effect of prosthetic contours on the changes in tissues following free gingiva graft procedure. MATERIAL AND METHODS A total of 53 implants in 32 patients receiving free gingiva grafts were selected. These had previously presented insufficient keratinized mucosa width (KMW). At the follow-up visits (mean: 16.66 ±9.97 months), the implant position and tissue condition were documented with an oral scanner. Vertical soft tissue thickness (VT), measured from the implant-abutment connection to the marginal tissues, and horizontal soft tissue thickness (HT), at the level of the platform, were calculated. The VT, HT and emergence angle (EA) of prostheses were assessed by 3Shape analyzing software. The final KMW was measured by clinical assessment. Marginal bone loss (MBL) was calculated in the follow-up bitewing radiographs. RESULTS The mean VT in the study was 2.65 ±0.75 mm at the mid-buccal sites, 3.74 ±1.22 mm at the mesial, 3.16 ±1.08 mm at the distal, and 2.53 ±0.92 at the mid-lingual aspects. The mid-buccal HT was 1.45 ±0.53 mm while the mid-lingual was 1.05 ±0.43 mm (P = 0.008). Interestingly, prostheses with mid-buccal EA>30∘ exhibited slightly lower VT, but higher HT, than the ones with EA≤30∘. Prostheses with proximal EA>30∘ displayed slightly more MBL, compared to prostheses with EA≤30∘. The mean KMW was 4.08 ±1.10 mm. CONCLUSIONS Free gingival grafting is a predictable treatment approach to augmenting soft tissue 3-dimensionally. Prostheses with EA≤30∘ were preferable for preserving the maximal VT and maintaining crestal bone stability. This article is protected by copyright. All rights reserved.

Abstract
AIM To assess the effect of surgical root coverage (RC) on dentin hypersensitivity (DH) associated with gingival recession. MATERIALS AND METHODS Two independent reviewers conducted electronic literature searches in MEDLINE (PubMed), EMBASE, Cochrane Library, Web Of Science, Dentistry & Oral Sciences Source, ScienceDirect, and ClinicalTrials.gov databases as well as a manual search to identify eligible clinical studies from January 2000 to March 2022. Randomized controlled trials (RCTs) comparing two surgical RC techniques or a surgical RC technique with or without adjuvant were included. Meta-analyses were performed on data provided by RCTs. RESULTS Thirteen RCTs with a total of 701 patients (1086 recessions) were included. The percentage of DH suppression was 70.8% (95% confidence interval [CI] [64.4-76.6]; I2 = 39.2% [3.5-61.8], Q-test = 0.02) after surgical RC. Recession reduction and percentage of RC were both statistically significantly associated with DH suppression (estimate = 0.66 [0.10-1.23], p = .022, R2 = 14.45% and estimate = 0.04 [0.01-0.08], p = .012, R2 = 29.54%, respectively). Coronally advanced flap (CAF) + connective tissue graft showed results statistically more effective than CAF + xenogeneic collagen matrix in DH suppression (73.3% [65.6-79.8] and 61.4% [51.7-70.3], respectively; p = .048). CONCLUSIONS Success of surgical RC is associated with DH suppression.

Abstract
BACKGROUND The natural Omega-3 lipids in the OADM serve to reduce inflammation. Preliminary results in a human model reported no adverse events and favorable healing and esthetic outcomes. OBJECTIVE The primary objective of this animal model study was to histologically evaluate the use of Omega-3 piscine acellular dermal matrix (OADM) as a soft tissue alternative in surgically created mucogingival defects. METHODS Bilateral maxillary canines in 6 adult beagle dogs were randomly assigned to the test (OADM) and control sub-epithelial connective tissue graft (SCTG) groups. Dehiscence defects 4 × 6 mm were created surgically on the buccal surfaces. The OADM/SCTG were placed to completely cover the root surface to the level of the cemento-enamel junction and sutured with resorbable sling sutures. The gingival flap was repositioned to cover the grafts. At two months follow-up, the dogs were sacrificed, and block samples were retrieved, including the whole canine and periodontium. The histological outcomes were evaluated using qualitative analysis. RESULTS The qualitative histological analysis revealed the oral, sulcular and junctional epithelium had healed with normal appearance on both test and control sites. None of the test (OADM) samples presented with any foreign body reaction. CONCLUSION The use of this new piscine xenograft resulted in minimal complications and the attachment apparatus healed normally.

Abstract
There is a shortage of suitable tissue-engineered solutions for gingival recession, a soft tissue defect of the oral cavity. Autologous tissue grafts lead to an increase in morbidity due to complications at the donor site. Although material substitutes are available on the market, their development is early, and work to produce more functional material substitutes is underway. The latter materials along with newly conceived tissue-engineered substitutes must maintain volumetric form over time and have advantageous mechanical and biological characteristics facilitating the regeneration of functional gingival tissue. This review conveys a comprehensive and timely perspective to provide insight towards future work in the field, by linking the structure (specifically multilayered systems) and function of electrospun material-based approaches for gingival tissue engineering and regeneration. Electrospun material composites are reviewed alongside existing commercial material substitutes’, looking at current advantages and disadvantages. The importance of implementing physiologically relevant degradation profiles and mechanical properties into the design of material substitutes is presented and discussed. Further, given that the broader tissue engineering field has moved towards the use of pre-seeded scaffolds, a review of promising cell options, for generating tissue-engineered autologous gingival grafts from electrospun scaffolds is presented and their potential utility and limitations are discussed.

Abstract
BACKGROUND Due to increasing numbers of adult patients, orthodontists are being confronted more and more with periodontal problems. Coordination amongst orthodontists, periodontists and general dentists is useful in preventing and stopping periodontal disease. The main objectives of this survey were to evaluate the technical knowledge, techniques and attitudes employed by French orthodontists, periodontists and general dentists in adult dental care. METHODS A cross-sectional online survey was distributed to French dentists. The questionnaire, consisting of 30 questions, was divided into six sections covering treatment programs and the forensic environment. RESULTS One thousand one hundred twenty-two complete answers were recorded. Adults undergoing orthodontic treatment represented 19.9% of the orthodontists' patients, but only 2.67% of the general dentists' patients. Communication between clinicians was rated as good, greater than 3 out of 5. Before treatment, orthodontists were less alarmed than generalists regarding bleeding, recessions, increased probing depths, halitosis and hyperplasia. During treatment, orthodontists never or only occasionally performed palpation or probing in 54.2% and 84.6% of cases. Gingivitis and recessions were the main reasons for consultations for 22.0% and 20.1% of general dentists and periodontists after orthodontic treatment. Of the practitioners surveyed, 43% felt that they experienced a setback in the ortho-periodontal treatment. CONCLUSIONS This study revealed discrepancies in the knowledge and attitudes of practitioners. Therapeutic management remains one of the major challenges of multidisciplinary treatments. Continuing education needs to be further developed in this field.

Abstract
Thin gingival phenotype (GPh) may contribute to periodontal tissue breakdown and recession development. Thus, the early identification of thin GPh in children can allow proper preventive care and the identification of children at risk during orthodontic treatment. The present long-term study aimed to monitor GPh changes, i.e., thickness (GT) and width of attached gingiva (AGW) during the early transitional dentition phase, as well as its potential associations with the mucogingival deformities. Materials and Methods: 83 systematically healthy children were examined twice with an interval of 2 years. Probing depth, GT and AGW at mandibular incisors, vestibular depth, type of lower lip frenum attachment and mucogingival defects were recorded. Results: 95.2% of participants at baseline and 93.9% at 2-year examination expressed thin GPh. During the transition from the deciduous to permanent dentition, GT and AGW declined, but the GT of permanent incisors already erupted at the baseline examination increased in the observation period. Conclusions: Gingival phenotype undergoes changes in the early transitional dentition phase. In spite of the thin gingival phenotype, only single pseudo-recessions and primary shallow vestibule were noticed.

Abstract
OBJECTIVES This study aimed to evaluate the effect of photobiomodulation therapy (PBMT) on patient morbidity and donor site healing after free gingival graft (FGG) harvesting. METHODS Forty-four patients requiring FGG were selected for this trial. Individuals were randomly assigned to test group (PBMT, n=22) or control group (placebo, n=22) applied immediately after surgery, 24 and 48 hours after. Demographic, surgical-related and psychosocial variables possibly associated with treatment response were collected. The primary outcome was postoperative pain at the donor site evaluated using Visual Analogue Scale (VAS) immediately after surgery and 6, 24, 48 and 72 hours after. Secondary outcomes include medication consumption, patient-reported outcome measures (PROMs) and percentage of wound closure. RESULTS Intragroup analysis showed no differences in VASLog means for placebo group throughout the study (p>0.05), whereas a significant difference in PBMT group at 6h, 24h, 48h and 72h (p<0.05) were observed. Postoperative rescue analgesic requirement was significantly higher in the placebo group (p=0.004). The number needed to treat(NNT) was 2.43. PBMT group reported significant better function related to sleeping, going to work/school and daily routine activities, less restriction to mouth opening, chewing and food consumption, less swelling and bleeding (p<0.05), mainly in the first 48hs. PBMT group presented a significantly higher palatal wound closure at 7 days compared to placebo group (33.41 vs 21.20 respectively, p=0.024) after adjustment for confounding. No adverse effects were reported. CONCLUSIONS PBMT accelerated the pain resolution time and palatal closure, decreased rescue medication consumption and significantly improved patient satisfaction in the postoperative period.

Abstract
The objectives of this study were to assess gingival recessions (GR) and periodontal status in patients previously treated with non-extraction orthodontic treatment and retention at a follow-up of a minimum of two years after the end of treatment. Data from patients aged between 16 and 35 years with a previous non-extraction orthodontic treatment and at least 2 years of retention and full records before and after treatment were collected. The casts were digitalized using the 3Shape TRIOS® intraoral scanner and the Viewbox4 software was used for the measurements. The following parameters were scored: inclination of the lower and upper incisors (IMPA and I^SN) and anterior crowding (Little index). The included patients were recalled for a clinical periodontal follow-up examination and the following parameters were evaluated: buccal and lingual GR (mm) of incisors and canines, bleeding of probing score, plaque score, and gingival phenotype. The digital cast analysis showed a mean Little index of 7.78 (SD 5.83) and 1.39 (SD 0.79), respectively, before and after treatment. The initial and final cephalometric analyses showed an I^SN of 103.53° and 105.78°(SD 7.21) and IMPA of 91.3°and 95.1°, respectively. At the follow-up periodontal visits, the patients showed an overall low oral hygiene with bleeding at probing in 66.6% and plaque in the anterior area in 76.2% of patients. From the total examined 240 teeth of the frontal sextants, three patients had GR (from 1 to 6.5 mm): in the upper arch two at canines and one at central incisor, whereas in the lower arch two at central and one at lateral incisors. The gingival phenotype was thick in 55% of cases. The lingual-to-lingual retainers at follow-up were present in 61.9% of patients. A slight increased risk for buccal GR development was found only in correlation with the presence of fixed retainer and thin gingival phenotype mainly in patients with gingivitis. Thus, non-extraction orthodontic treatment performed with controlled forces and biomechanics seems to not affect the development of GR or the periodontal health after retention.

Abstract
Background and Objectives: Dental occlusion and gingival recession have been studied over the past years especially because of the increasing incidence of occlusal interferences in young patients. The purpose of this pilot study is to investigate any association between occlusal dysfunctions and gingival recessions. Data on gingival phenotype and previous orthodontic treatment were also collected to assess any correlation with the presence of gingival recession. Materials and Methods: Forty systemically healthy subjects, without signs of periodontitis and with gingival recessions, were included in the study. The following parameters were determined: location and extent of the gingival recession, gingival phenotype and functional occlusion by means of observing and registering the occlusal contacts in maximum intercuspation position, protrusive and lateral guidance. Results: Premolars were mostly affected in cases of working-side interferences during lateral guidance (71.19% of the affected teeth during left and 75% during right mandibular movements). The chi-squared exact test applied for the analysis of contingency tables revealed statistically significant associations between excursive interferences during lateral guidance and anterior guidance and the presence of gingival recession on the involved group of teeth. Conclusions: The results suggest that most gingival recessions might be associated with working-side interferences, the highest number of gingival recessions being associated with active interferences during lateral guidance.

Abstract
OBJECTIVES The aim of the study was the long-term assessment of the condition of periodontal tissues after corticotomy-assisted orthodontic expansion in patients with transverse maxillary deficiency. MATERIALS AND METHODS The study included a group of 18 adults (9 women, 9 men) aged between 24 and 40 years who were at least 5 years post treatment. The following parameters were assessed: the full mouth plaque index (FMPI), full mouth bleeding on probing (FMBOP), probing depth (PD), clinical attachment level (CAL), gingival recession height (GR), recession width (RW), papilla height (PH), papilla width (PW), bone sounding (BS), phenotype, and KT. RESULTS During examination performed at least 5 years after the completion of orthodontic treatment, the values of PD and CAL were found to be considerably decreased compared to the examination one year post treatment (PD: -0.23; 95% Cl: -0.29, -0.16) (CAL: -0.04; 95% Cl: -0.17, 0.10). The other parameters-FMPI, FMBOP, GR, RW, PH, PW, BS, phenotype, and KT-did not change significantly. CONCLUSIONS Corticotomy-assisted orthodontic arch expansion does not have a negative effect on the periodontium in long-term observations. CLINICAL RELEVANCE Orthodontic arch expansion can lead to bone dehiscence and gingival recession. Long-term observations revealed that corticotomy-assisted orthodontic expansion of the upper arch is not followed by negative changes in periodontal status.

Abstract
OBJECTIVES Gingival unit graft (GUG) is defined as the modified form of free gingival graft. The aim of this study is to compare the clinical efficacy of GUG with connective tissue graft (SCTG) with respect to clinical periodontal parameters and patient comfort scores in gingival recessions. MATERIALS AND METHODS Sixteen patients with bilateral recession type 1 (RT1) gingival recessions participated in this randomized and split-mouth study. Thirty-two defects received surgical treatment with SCTG or GUG. The recession defect coverage, periodontal measurements, and patient-reported outcomes (intra- and post-operative patient comfort, aesthetic satisfaction, and hypersensitivity) were evaluated at baseline and post-operative months 1, 3 and 6. RESULTS The favorable results were obtained in both study groups in gingival recession depth (RD), gingival recession width (RW), clinical attachment level (CAL), and keratinized tissue width (KTW). The average percentages of the recession defect coverage (RC) for GUG and SCTG group treatments after 6 months were 68.2 ± 33% and 76.4 ± 30.2%, respectively (p > 0.05). Although there was no significant difference between groups at post-operative 6 months (p > 0.05) in terms of RD, RW, CAL, RC, patient comfort, aesthetic satisfaction, and hypersensitivity parameters, the increase in KTW was significantly higher in GUG group (p < 0.05). CONCLUSIONS It was concluded that although both techniques were effective, GUG can be a convenient method for treatment of RT1 gingival recessions with inadequate KTW and (or) shallow vestibule depth. CLINICAL RELEVANCE According to the results of this study, GUG may be a preferred choice in localized gingival recessions with a lack of keratinized tissue. The trial registration number: NCT04637451.

Abstract
Introduction The purpose of this case report was to show the clinical long-term stability of a successful two-step root coverage procedure. A combination of two single techniques was used to treat an isolated deep-wide defect. Case Presentation. A 28-year-old female patient was referred in order to treat a single recession defect at #22. Due to her fear of dental procedures and a poor economic situation, the team developed an alternative solution. They used a modified apically repositioned flap (MARF) to increase the donor area and then a laterally positioned flap (LPF) to treat the root defect. Clinical evaluation at the three-year follow-up revealed complete resolution of the defect, a gain in clinical attachment, excellent esthetic results, and minor morbidity to the patient. Conclusion The combination of the MARF and the LPF procedures was able to successfully treat a single deep recession defect with some advantages over traditional techniques such as simplicity, ideal color match of tissues, and the absence of palatal donor tissue.

[PMID: 34229922 DOI: 10.1016/j.ijom.2021.06.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2020] [Revised: 06/07/2021] [Accepted: 06/22/2021] [Indexed: 11/25/2022]
Abstract
The purpose of this study was to report the outcomes of interpositional osteotomy with mineralized allograft in the treatment of alveolar vertical defects in preparation for implant placement. Thirteen defects (11 maxillary and two mandibular) were treated with osteotomy segments ranging in length from two to five missing teeth. The segments were positioned 5-7 mm coronally, with the gap space filled with allograft and then fixated with titanium hardware. Vertical bone augmentation was analyzed by superimposing pre- and post-surgical cone beam computed tomography images and stratified based on the length and number of missing teeth in each edentulous segment. The mean vertical bone gain was 3.7 ± 1.6 mm in the area of greatest vertical defect and the mean length of the transport segment was 20.5 ± 8.1 mm. These segments represented two-, three-, four-, or five-tooth edentulous sites; the mean vertical bone gain for these segments was 1.7 ± 0.5 mm, 3.8 ± 1.0 mm, 4.6 ± 0.9 mm, and 6.7 ± 0.0 mm, respectively. Stability of vertical height gain was found to be directly proportional to the span length of the osteotomy segment, with the largest five-tooth segment achieving the greatest gain. Vertical bone gain in two-tooth segments was minimal, indicating a moderate amount of resorption.

Alsalhi RH, Tabasum ST. Prevalence of gingival recession and its correlation with gingival phenotype in mandibular incisors region of orthodontically treated female patients: A cross-sectional study. J Indian Soc Periodontol 2021; 25:341-346. [PMID: 34393406 PMCID: PMC8336773 DOI: 10.4103/jisp.jisp_526_20] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2020] [Revised: 12/25/2020] [Accepted: 02/09/2021] [Indexed: 12/22/2022] Open
Abstract
Background: Gingival recession is associated with dentin hypersensitivity, unesthetic appearance, and carious or noncarious cervical lesions. Orthodontic treatment, gingival thickness (GT), and keratinized tissue width (KTW) play roles in gingival recession etiology. The study is aimed to compare the prevalence of gingival recession in the mandibular incisor region of orthodontically-treated females with untreated controls, and to identify if there is any correlation among the GT, KTW, and gingival recession. Subjects and Methods: A total of 150 Saudi females were enrolled in this study. They were categorized into the treatment group (n = 75) and control group (n = 75). Background characteristics and clinical periodontal parameters including the plaque index, gingival index, GT, KTW, gingival recession length (GRL), and gingival recession width (GRW) were recorded and compared between groups, and any associations were identified. Results: Among the orthodontically-treated females, 31 (41.33%) had at least one mandibular incisor with gingival recession, in contrast to 18 (24%) of the controls. Pearson's correlation analysis indicated a significant positive correlation between the GT and KTW and between the GRL and GRW (P < 0.001). In addition, a significant negative correlation was observed between the KTW and GRL and between the KTW and GRW (P < 0.001). However, no significant correlation was found between the GT and GRL or between the GT and GRW. Conclusions: Our findings indicated that orthodontic treatment is a predisposing factor for the development or progression of gingival recession, particularly in females with a narrow KTW.

Abstract
BACKGROUND Complications after free gingival graft (FGG) operations are generally related to the donor site. The titanium-prepared, platelet-rich fibrin (T-PRF) placement in the donor site accelerate the wound healing and prevent postoperative complications such as pain and hemorrhage. We aim to evaluate the effect of T-PRF regarding vascularization and tissue thickness and to report the advantages of the ultrasonography (US) in FGG. METHODS Ten individuals were divided into two groups as T-PRF and control. While the T-PRF membrane was placed at the donor site in the T-PRF group, a gelatin sponge was placed in the control group. All patients underwent US examination in terms of vascularization and tissue thickness of left and right donor sites. The correlation between the right and left donor sites was analyzed with the Pearson correlation test. Tissue thicknesses and pulsatility index (PI) were analyzed with independent samples t-test. The results were evaluated statistically at the P <0.05 significance level. RESULTS The T-PRF group showed increased vascularity which can be interpreted to improve healing in soft tissue. However, not a difference, but a positively very high correlation was observed between the right and left tissue thicknesses (P = 0,00; r = +0902). CONCLUSIONS Evaluation of tissue thickness and vascularization density of donor sites with US not only increases clinical success rate but also reduces the risk of complications during surgery and postoperative pain in FGG. Studies evaluating T-PRF membrane as palatal dressing after FGG are only clinical, however, the efficiency of T-PRF was evaluated radiologically in this study for the first time.

Abstract
Objective: Free gingival graft (FGG) procedure is accompanied with a considerable rate of graft shrinkage. This study was aimed to assess the dimensional changes of FGG after recipient site preparation with Er,Cr:YSGG laser and surgical scalpel. Materials and methods: This split-mouth randomized clinical trial evaluated 11 patients with bilateral lack of keratinized gingiva in mandibular premolars. The test side in each patient was prepared with Er,Cr:YSGG laser (3 W power, 300 mJ energy, 10 Hz frequency, long-pulsed mode), whereas the control side was prepared by surgical scalpel. All FGGs were harvested from the palate with standard dimensions of 14 × 9 mm. The graft width, length, surface area, and shrinkage and color match were measured after 1, 3, and 6 months. Postoperative complications, including pain and bleeding were also evaluated using a questionnaire. Results: In both groups, the surface area and width of graft significantly decreased at all time points compared with baseline but the difference in this respect was not significant between the two groups (p > 0.05). In both groups, maximum shrinkage occurred within the first 3 months. In control group, the surface shrinkage in 3 months was significantly greater than the first month (p = 0.025) without significant difference between groups (p = 0.79). The two groups were not significantly different regarding pain score and bleeding score either. On the day of surgery, the test group had slightly lower pain score and higher bleeding score in comparison to the control group without significant difference. The pain and bleeding scores reduced in both groups with no significant difference (p > 0.05). Conclusions: Er,Cr:YSGG laser has promising results for preparation of FGG recipient site and yields results comparable to those of surgical scalpel.

Abstract
OBJECTIVE The current cross-sectional study aimed to investigate the prevalence of gingival recession (REC) in a sample of young individuals. In addition, the association with several risk factors was examined. MATERIALS & METHODS A 104 subjects, aged 18-30 years old, were randomly enrolled in the study. Participants were requested to fill in a simple structured questionnaire in order to provide information on dental hygiene habits, educational level, smoking and history of orthodontic treatment. Afterwards, all the included individuals were subjected to a thorough clinical periodontal examination including gingival recession (REC), gingival biotype, plaque levels and gingival bleeding index (GBI) assessment. RESULTS The mean prevalence of REC in the studied population surpassed 50% with an equal distribution among females and males. The most common teeth associated with REC were the lower left canine and left 1st premolar. Among the examined variables, only the bleeding index was found to be associated with the presence of REC. CONCLUSIONS Gingival recession was a prevalent condition among young individuals. Gingival inflammation was found to be the most significant factor affecting the incidence of REC.

Abstract
Objectives Many acellular dermal matrices (ADMs) are available for use in periodontal surgical procedures. However, few studies exist evaluating their in vivo healing properties. The objectives of this study were to compare the wound healing and remodeling of two ADMs used for gingival augmentation procedures in the rat model. Materials and methods This was a nonrandomized controlled split‐mouth study. Envelope flaps were surgically created in the maxillary quadrants of 24 Sprague Dawley rats. Each received either (a) AlloDerm Regenerative Tissue Matrix, or (b) OrACELL. Gingival tissue from one mandibular quadrant served as the untreated control. Six male and six female rats were treated for 7 or 21 days. Biopsies were processed for histologic analysis (H&E, Picro‐sirius red, Verhoeff's solution) or RNA analysis (RT‐PCR) to analyze the expression of type I collagen (Col1a1), fibronectin (Fn‐1) and VEGF‐A (Vegf‐A). Results There was a greater density of fibroblasts in OrACELL compared to AlloDerm at both timepoints. There was a greater density of elastin present in AlloDerm compared to OrACELL at 7 days but no differences at 21 days. There were no differences between test groups in the percentage of birefringent collagen or in the expression of Vegf‐A or Fn‐1. At 7 days, there were significantly more fibroblasts for males in the OrACELL group compared to females. At 21 days, there was a significantly greater expression of Col1a1 for males in the OrACELL group compared to females. Conclusions Early wound healing and remodeling of OrACELL appeared to occur more rapidly than AlloDerm and was accelerated in male rats. Whether these results have clinical implications for soft tissue grafting procedures in humans remains to be determined.

Abstract
Background Protection of the palatal wound is an essential step following harvesting a palatal soft tissue graft. The aim of the current pilot randomized clinical study was to assess the efficacy of using propylene mesh as protective sheet when compared to conventional custom made acrylic stent after harvesting a palatal graft. The primary outcome of this study was bleeding postoperatively and secondary outcomes were pain, healing profile of the donor site as well as patient satisfaction.
Methods Between 2018 and 2019 we conducted a prospective randomized controlled trial of 24 patients with palatal defects. Two groups of 12 patients with 24 sites were included in this study and were treated with soft tissue grafting technique using free grafts harvested from the hard palate. The palatal wounds were protected with propylene mesh (test group) or custom-made acrylic palatal stent (control group). Participants were assessed for the amount and duration of bleeding, pain duration, and the risk of infection 2, 4, 6, 8, 14 days post-operatively. The trial had been registered in clinical trials.gov (NCT04348279). Results Four sites were excluded from the study as dropouts. The polypropylene mesh was more effective at reducing bleeding by (2.4 ± 1.075) and pain by (1.600 ± 0.516), while the custom-made acrylic stent reduced the bleeding (5.8 ± 1.22) and pain (7.100 ± 0.316). The decline in amount of bleeding amount (P value = 0.021) and its duration (P value = 0.001) achieved by the propylene mesh was statistically significant. There was no statistical significant difference in patient satisfaction and the duration of healing process between the 2 groups. However, the healing profile of the test group was statistically significant when compared with the control group (P value = 0.002). Conclusions Propylene mesh is a promising material for protection of the palatal wound due to its light weight, limited bacterial wicking, tissue compatibility. Further studies are required to adequally assess the benefits of this material in periodontal plastic surgeries.

Abstract
This research aims to evaluate the clinical and histological parametric differences concerning keratinized tissue that result from two regeneration techniques, the subepithelial autologous connective tissue graft (ACTG) and the acellular dermal matrix (MD) of porcine origin, performed on surgical beds on edentulous spaces in an animal model. The parameters of the MD and ACTG groups were compared with samples of the control group (CG) after 15, 45, and 90 days. Nine female white pigs (Sus scrofa domestica) were used, and each animal provided 20 study areas (12 MD and 8 ACTG). At 15 days, the keratin layer thickness in the MD group was greater than those of the ACTG (25.27 vs. 19.95 μm) and the CG (21.2 μm). After 45 days, the MD and ACTG thickness values decreased but were higher than the CG. At 90 days, MD (19.46 μm) obtained a value close to that of CG, and the ACTG decreased to CG (15.53 μm, p < 0.001). The use of an MD may be a viable alternative to the ACTG because of its ability to provide increased keratinized tissue in comparison to the ACTG.
