Abstract
Bone regeneration is a critical area in regenerative medicine, particularly in orthopedics, demanding effective biomedical materials for treating bone defects. 45S5 bioactive glass (45S5 BG) is a promising material because of its osteoconductive and bioactive properties. As research in this field continues to advance, keeping up-to-date on the latest and most successful applications of this material is imperative. To achieve this, we conducted a comprehensive search on PubMed/MEDLINE, focusing on English articles published in the last decade. Our search used the keywords "bioglass 45S5 AND bone defect" in combination. We found 27 articles, and after applying the inclusion criteria, we selected 15 studies for detailed examination. Most of these studies compared 45S5 BG with other cement or scaffold materials. These comparisons demonstrate that the addition of various composites enhances cellular biocompatibility, as evidenced by the cells and their osteogenic potential. Moreover, the use of 45S5 BG is enhanced by its antimicrobial properties, opening avenues for additional investigations and applications of this biomaterial.

Abstract
Aim: This study aims to evaluate and validate the sensibility and the level of agreement between different gingival color measures obtained by a spectrophotometer (SPECTRO) and a photography (PHOTO) method. Methods: Among 40 patients, the color was measured 2 mm apical to the gingival margin by CIE L*, a*, b* system using a reflectance spectrophotometer and the photography’s plus software. The level of agreement between three different measures (m1, m2, m3) in parameters L*, a*, b*, and ΔE (color variation) was evaluated by random and systematic errors, as well as the limits and coefficient of concordance. A comparison between the methods was performed by the Bland-Altman test and the sensibility level was evaluated accordingly to the ΔE: 3.7 thresholds with p<0.05 as the level of significance for these comparisons. Results: The SPECTRO method has not presented the systematic error (p>0.05) and had reproducibly and agreement level in three variable measures L* (r: 0.6), a* (r: 0.3), and b* (r: 0.5) as to the PHOTO method L* (r: 0.6), a* (r: 0.5), and b* (r: 0.5), which presented systematic error in L* values (p<0.05). The means of ΔE between measurements were: 6.5 SPECTRO and 5.9 PHOTO. There was no good level of sensitivity ΔE> 3.7 and agreement between the methods, mainly for the a* values. On the other hand, for the L* and in for the most comparisons of b* values, the level of agreement was higher. Conclusion: Both methods could quantify the gingival color from the coordinates L *, a *, and b *, which has shown greater reliability between the measurements acquired by the SPECTRO method.

Abstract
Objective Gestational diabetes mellitus (GDM) causes maternal and infant morbidity. Periodontitis is associated with adverse pregnancy outcomes. The aim of this study was to evaluate periodontal status, prematurity and associated factors in pregnant women with and without GDM. Methods This observational cross-sectional study included 80 pregnant women with GDM (G1 = 40) and without GDM (G2 = 40). Demographic and socioeconomic status, systemic and periodontal health condition, prematurity and newborns' birth weight were analyzed. For bivariate analysis, Mann-Whitney U-test, t test and Chi-squared test were used. Binary logistic regression analyzed independent variables for periodontitis and prematurity (p < 0.05). Results Patients from G1 presented lower socioeconomic status, higher weight and body mass index (BMI). Prematurity (G1 = 27.5%; G2 = 2.5%; p < 0.05) and severe periodontitis percentages (G1 = 22.5%; G2 = 0; p = 0.001) were higher in G1 than in G2. Logistic regression analysis showed that household monthly income (OR = 0.65; 95% CI 0.48-0.86; p = 0.003) and maternal BMI (adjusted OR = 1.12; 95% CI 1.01-1.25; p = 0.028) were significant predictors of periodontitis during the third trimester of pregnancy. Presence of GDM remained in the final logistic model related to prematurity (adjusted OR = 14.79; 95% CI 1.80-121.13; p = 0.012). Conclusion Pregnant women with GDM presented higher severity of periodontitis, lower socioeconomic status, higher overweight/obesity and a 10-fold higher risk of prematurity. Socioeconomic-cultural status and BMI were significant predictors for periodontitis, and GDM was a predictor to prematurity.

Abstract
In this experimental protocol, the objective was to evaluate the biological behavior of two xenogenic scaffolds in alcohol-induced rats through histomorphometric and Picrosirius Red staining analysis of non-critical defects in the tibia of rats submitted or not to alcohol ingestion at 25% v/v. Eighty male rats were randomly divided into four groups (n = 20 each): CG/B (water diet + Bio-Oss® graft, Geistlich Pharma AG, Wolhusen, Switzerland), CG/O (water diet + OrthoGen® graft, Baumer, Mogi Mirim, Brazil), AG/B (25% v/v alcohol diet + Bio-Oss® graft), and AG/O (25% v/v alcohol diet + OrthoGen® graft). After 90 days of liquid diet, the rats were surgically obtained, with a defect in the tibia proximal epiphysis; filled in according to their respective groups; and euthanized at 10, 20, 40 and 60 days. In two initial periods (10 and 20 days), all groups presented biomaterial particles surrounded by disorganized collagen fibrils. Alcoholic animals (AG/B and AG/O) presented, in the cortical and medullary regions, a reactive tissue with inflammatory infiltrate. In 60 days, in the superficial area of the surgical cavities, particles of biomaterials were observed in all groups, with new compact bone tissue around them, without complete closure of the lesion, except in non-alcoholic animals treated with Bio-Oss® xenograft (CG/B), where the new cortical interconnected the edges of the defect. Birefringence transition was observed in the histochemical analysis of collagen fibers by Picrosirius Red, in which all groups in periods of 10 and 20 days showed red-orange birefringence, and from 40 days onwards greenish-yellow birefringence, which demonstrates the characteristic transition from the formation of thin and disorganized collagen fibers initially to more organized and thicker later. In histomorphometric analysis, at 60 days, CG/B had the highest volume density of new bone (32.9 ± 1.15) and AG/O the lowest volume density of new bone (15.32 ± 1.71). It can be concluded that the bone neoformation occurred in the defects that received the two biomaterials, in all periods, but the Bio-Oss® was superior in the results, with its groups CG/B and AG/B displaying greater bone formation (32.9 ± 1.15 and 22.74 ± 1.15, respectively) compared to the OrthoGen® CG/O and AG/O groups (20.66 ± 2.12 and 15.32 ± 1.71, respectively), and that the alcoholic diet interfered negatively in the repair process and in the percentage of new bone formed.

Abstract
AIMS Gingival recession has been associated with dentin hypersensitivity and aesthetic impairment. The impact of gingival recession and periodontal surgical procedures on adult patients' quality of life are scarce. The aim of this study was to evaluate the quality of life of patients submitted to root coverage procedures with subepithelial connective tissue grafts and coronally advanced flap. MATERIALS AND METHODS Patients were asked to use a numerical rating scale to classify their dentin hypersensitivity, aesthetics, pain/discomfort, chewing, and brushing abilities in gingival recession sites treated with subepithelial connective tissue grafts plus coronally advanced flap. The patients answered a self-administered questionnaire about quality of life-related to oral health (OHIP-14) after 7, 14, 30, 90, and 180 days. Descriptive statistics were used to synthesize the data recorded. RESULTS Mean percentage of root coverage was positively related to OHIP-14 (dimension 2- physical pain) in 90 days postoperatively. The quality of life (OHIP-14 total score) significantly improved from baseline to 90 and 180 days postoperatively. The numerical rating score analysis revealed significant improvement in the chewing and brushing abilities when period of 7 days was compared to 90 and 180 days and from 14 to 180 days. CONCLUSIONS Root coverage procedures with subepithelial connective tissue grafts plus coronally advanced flap result in a positive effect on adult patients' quality of life.

Abstract
Systemic lupus erythematosus (SLE) is a complex chronic autoimmune disease characterized by tissue damage and widespread inflammation in response to environmental challenges. Deposition of immune complexes in kidneys glomeruli are associated with lupus nephritis, determining SLE diagnosis. Periodontitis is a chronic inflammatory disease characterized by clinical attachment and bone loss, caused by a microbial challenge – host response interaction. Deposition of immune complex at gingival tissues is a common finding in the course of the disease. Considering that, the primary aim of this study is to investigate the deposition of immune complexes at gingival tissues of SLE patients compared to systemically healthy ones, correlating it to periodontal and systemic parameters. Twenty-five women diagnosed with SLE (SLE+) and 25 age-matched systemically healthy (SLE–) women were included in the study. Detailed information on overall patient's health were obtained from file records. Participants were screened for probing depth (PD), clinical attachment loss (CAL), gingival recession (REC), full-mouth bleeding score (FMBS) and plaque scores (FMPS). Bone loss was determined at panoramic X-ray images as the distance from cementenamel junction to alveolar crest (CEJ-AC). Gingival biopsies were obtained from the first 15 patients submitted to surgical periodontal therapy of each group, and were analyzed by optical microscopy and direct immunofluorescence to investigate the deposition of antigen-antibody complexes. Eleven (44%) patients were diagnosed with active SLE (SLE-A) and 14 (56%) with inactive SLE (LES-I). Mean PD, CAL and FMBS were significantly lower in SLE+ than SLE–(p < 0.05; Mann Whitney). The chronic use of low doses of immunosuppressants was associated with lower prevalence of CAL >3 mm. Immunofluorescence staining of markers of lupus nephritis and/or proteinuria was significantly increased in SLE+ compared to SLE–, even in the presence of periodontitis. These findings suggest that immunomodulatory drugs in SLE improves periodontal parameters. The greater deposition of antigen-antibody complexes in the gingival tissues of patients diagnosed with SLE may be a marker of disease activity, possibly complementing their diagnosis.

Abstract
Aim This case series demonstrated that phthalocyanine derivate mouthwash is a promising alternative for reducing the viral load of SARS-CoV-2 and for clinical improvement of infected patients who presented mild and moderate symptoms. Purpose The aim of this study was to report a case series of patients diagnosed with COVID-19 that used the phthalocyanine derivate mouthwash to reduce clinical symptoms. Patients and Methods Eight patients used 5mL of phthalocyanine derivate mouthwash gargling/rinsing for one minute, five times daily, over a fourteen day period. Two measurement scales were applied for each patient in different periods to verify sore throat – VAS – Visual Analogue Scale for Pain and the clinical conditions – PS – Performance Status. Results All patients presented a significant reduction in clinical symptoms with the use of the mouthwash for gargling/rinsing after few days of use, without hospitalization. Conclusion The phthalocyanine derivate mouthwash protocol appears as a potential alternative for clinical improvement of COVID-19 infected patients. Daily use of this mouthwash rapidly reduced clinical symptoms such as sore throats, cough and mouth ulcers. Large, high-quality randomized controlled trials with larger sample size are necessary to confirm the effectiveness of this mouthwash protocol against COVID-19.

Abstract
AIM This prospective cohort study evaluated late complications (LC) on recipient sites comparing two types of connective tissue grafts (CTG). MATERIALS AND METHODS Participants (n: 60) were treated with coronally advanced flap (CAF) plus CTG harvested by de-epithelialized technique (DE) (n:31) or two-parallel incision (PI) (n:29). Areas were evaluated to identify white discharge associated or not with gingival cul-de-sac. Patients were ordered in groups with (DE+and PI+) or without (DE- and PI-) LC. Biopsies for histopathological analysis in LC areas were proposed. RESULTS Six cases exhibited LC, 5 in DE graft (DE+) and 1 in PI graft (PI+) group; 2 were diagnosed at 3 months postoperatively, 3 at 6 months and one at 12 months. The relative risk for LC was 1.7 times greater for DE graft (p: 0.01; CI: 1.10 to 2.72; RR>1). Differences were not observed for clinical outcomes after both types of CTGs (p > 0.05). Biopsies showed deep invagination of the epithelial lining suggesting cyst-like area/ cavity with keratin content and consolidated in fibrous connective tissue. After 24 months biopsied areas presented no recurrence of LC, in non-biopsied patients the clinical condition remained unchanged. CONCLUSIONS Considering the limitations of this study, LC on recipient sites demonstrated no statistical difference between two types of CTG.

Abstract
BACKGROUND This split-mouth randomized clinical trial compared two different types of subepithelial connective tissue grafts (SCTG) considering clinical parameters and patient-centered outcomes in patients with bilateral recession type 1 multiple gingival recessions after 6 months postoperatively. METHODS A total of 21 patients were surgically treated with coronally advanced flap (CAF) associated with SCTG harvested by: double blade scalpel (DBS) and de-epithelialized (DE) SCTG. Periodontal clinical parameters and esthetics were evaluated by a calibrated periodontist at baseline and after 6 months. Patient-centered outcomes related to pain/discomfort and esthetics were assessed with visual analogue scale after 7 days and 6 months, respectively. RESULTS All clinical parameters, with the exception of probing depth, demonstrated differences in intragroup evaluation, comparing baseline to 6-month evaluation (P <0.05). Both groups presented reduction of recession depth and recession width and gain of keratinized tissue thickness, keratinized tissue width, and clinical attachment level (P <0.05). Intergroup comparison (DBS × DE) demonstrated no significant differences considering clinical parameters and periods. Both techniques improved esthetics evaluated by patients, without a difference between groups in patients and professional analysis. However, DBS group presented inferior pain/discomfort compared with DE (P <0.05). CONCLUSION DBS and DE associated with CAF presented satisfactory clinical outcomes. However, DBS presented inferior morbidity, an important fact for decision-making process.

Abstract
PURPOSE The aim of this study was to investigate the response of osteogenic cell lineage and gingival fibroblastic cells to different surface treatments of grade IV commercially pure Titanium (cpTi) disks. MATERIAL AND METHODS Grade IV cpTi disks with different surfaces were produced: machined (M), sandblasting (B), sandblasting and acid subtraction (NP), and hydrophilic treatment (ACQ). Surface microtopography characteristics and chemical composition were investigated by scanning electron microscopy (SEM) and energy dispersive x-ray spectrometry (EDS). Adhesion and proliferation of SC-EHAD (human surgically-created early healing alveolar defects) and HGF-1 (human gingival fibroblasts) on Ti disks were investigated at 24 and 48 h, and osteogenic differentiation and mineralization were evaluated by assessing alkaline phosphatase (ALP) activity and alizarin red staining, respectively. RESULTS No significant differences were found among the various surface treatments for all surface roughness parameters, except for skewness of the assessed profile (Rsk) favoring M (p = 0.035 ANOVA). M disks showed a slightly higher (p > 0.05; Kruskal-Wallis/Dunn) adhesion of HGF-1 (89.43 ± 9.13%) than SC-EHAD cells (57.11 ± 17.72%). ACQ showed a significantly higher percentage of SC-EHAD (100%) than HGF-1 (69.67 ± 13.97%) cells adhered at 24 h. SC-EHAD cells expressed increased ALP activity in osteogenic medium at M (213%) and NP (235.04%) surfaces, but higher mineralization activity on ACQ (54.94 ± 4.80%) at 14 days. CONCLUSION These findings suggest that surface treatment influences the chemical composition and the adhesion and differentiation of osteogenic cells in vitro. CLINICAL RELEVANCE Hydrophilic surface treatment of grade IV cpTi disks influences osteogenic cell adhesion and differentiation, which might enhance osseointegration.

Abstract
The purposes of this study are to evaluate the effects of photobiomodulation (PBM) with laser and LED on rat calvaria osteoblasts (rGO lineage), cultured in osteogenic (OST) or regular (REG) medium, after induction of a quiescent state and to test if PBM is capable of osteogenic induction and if there is a sum of effects when combining OST medium with PBM. Before irradiation, the cells were put in a quiescent state (1% FBS) 24 h, when red (AlGaInP-660 nm) and infrared laser (GaAlAs-808 nm) and LED (637 ± 15 nm) were applied. The groups were as follows: red laser (RL3-5 J/cm2, 3 s and RL5-8.3 J/cm2, 5 s, 1.66 W/cm2); infrared laser (IrL3-5 J/cm2, 3 s and IrL5-8.3 J/cm2, 5 s); LED (LED3-3 s and LED5-5 s, 0.02 J/cm2, 0.885 W/cm2); positive (C+, 10% FBS) and negative control (C-, 1% FBS). For alkaline phosphatase (ALP) and mineralization assays, the cells were cultured in REG (DMEM 10% FBS) and OST medium (DMEM 10% FBS, 50 μg/mL ascorbic acid, 10 mM β-glycerophosphate). Statistical analysis was performed using ANOVA and Tukey's tests (p < 0.05). RL5 and LED5 increased proliferation, in vitro wound closure, ALP, and mineralization in rGO cells (p < 0.05). PBM with red laser and LED induced mineralization by itself, without osteogenic medium, not observed for infrared laser (p < 0.05). A sum of effects was observed in osteogenic medium and PBM by infrared, red laser, and LED (5 s). Red laser and LED increased proliferation, migration, and secretory phases in rGO cells in a dose-dependent manner. PBM with red laser and LED promotes osteogenic induction by itself. PBM with infrared laser and osteogenic medium potentializes mineralization.

Abstract
The importance of surgical intervention for the maintenance of long-term results by root coverage of multiple gingival recessions in an esthetic area treated with a tissue substitute (acellular dermal matrix [ADM]-Alloderm®) is widely required. The present case report highlights the effectiveness of the ADM for the treatment of multiple recession defects in a female patient with Class I and II gingival recession in relation to maxillary anterior associated with esthetics and dentin hypersensitivity demands. The root coverage rate for the anterior area showed greater value with 70% of coverage; at 90 days and 2 and 12 years of follow-up, it showed 70.5%, 79%, and 77%, respectively. Conversely, for the posterior area, these rates were 68.5%, 63%, and 57% for the same follow-up periods. Results regarding gain of keratinized tissue demonstrated superior values for the anterior area, namely 3.92, 3.34 and 3.22 mm at 90 days and 2 and 12 years. These values for the posterior area were 0.54 mm, 2.41, and 1.87 mm, respectively. These findings suggest that the tissue substitute Alloderm® showed excellent long-term results for areas of multiple recessions, providing root coverage and stability of keratinized tissue gain. After this long period of evaluation, some local factors associated with recurrence of gingival recessions were detected, and a lack of proper periodontal maintenance care was observed. However, esthetic and functional outcomes achieved with surgical procedure were maintained.

Abstract
Background: The aim of this study was to evaluate the cytotoxicity of cyanoacrylate adhesives in an indirect contact assay in human gingival fibroblast (FGH) and oral osteoblasts (GO) lineages. Methods: Cover glasses were glued with adhesives following the ISO 10993-2012 protocol. The groups were: C (control with cells and regular Dulbecco Modified Eagle Medium; LC (liquid ethyl-cyanoacrylate); GC (ethyl-cyanoacrylate gel); EGC (easy gel [ethyl-cyanoacrylate]); and D (Dermabond [octyl-cyanoacrylate]). Each cell linage was plated in the sixth passage using 104 cells. Cell viability was measured by the MTT test at 24, 48, 72, and 96 hours. Data were analyzed by two-way analysis of variance complemented by the Tukey test, with p < 0.05 being significant. Results: Dermabond stimulated osteoblast viability at 72 h (p < 0.05). All other groups were similar to the control cells (p > 0.05). For the fibroblasts, there was no difference in the groups, including the control except that EGC was cytotoxic for these cells (p < 0.05). Conclusions: Ethyl-cyanoacrylate gel and liquid forms available on the general chemical market were not cytotoxic for oral osteoblasts and fibroblasts in most cases. However, the easy gel form was cytotoxic for fibroblasts.

Abstract
Subepithelial connective tissue graft (SCTG) presents favorable outcomes. However, the harvesting technique can influence the anatomical and histological composition of the SCTG. Within the limitations of a case report, the behavior of SCTGs removed by two techniques was evaluated bilaterally in one patient using double blade scalpel (DBS) and de-epithelialized graft (DE). Clinical parameters, laser Doppler flowmetry (LDF) and histological analysis were assessed. Complete root coverage was observed bilaterally, as well as improvement in width and thickness of keratinized tissue 2 years postoperatively. The LDF analysis demonstrated better revascularization in the DBS recipient area compared to DE. The histological evaluation showed differences in tissue composition and organization of collagen fibers. Similar clinical outcomes were observed bilaterally, nevertheless greater morbidity and aesthetic was reported in the DE harvesting area.

Abstract
OBJECTIVES This split-mouth controlled randomized clinical trial evaluated clinical and histological results of acellular dermal matrix allograft (ADM) compared to autogenous free gingival graft (FGG) for keratinized tissue augmentation. MATERIAL AND METHODS Twenty-five patients with the absence or deficiency of keratinized tissue (50 sites) were treated with FGG (control group) and ADM (test group). Clinical parameters included keratinized tissue width (KTW) (primary outcome), soft tissue thickness (TT), recession depth (RD), probing depth (PD), and clinical attachment level (CAL). Esthetic perception was evaluated by patients and by a calibrated periodontist using visual analog scale (VAS). Histological analysis included biopsies of five different patients from both test and control sites for each evaluation period (n = 25). The analysis included percentage of connective tissue components, epithelial luminal to basal surface ratio, tissue maturation, and presence of elastic fibers. Data were evaluated by ANOVA complemented by Tukey's tests (p < 0.05). RESULTS After 6 months, PD and CAL demonstrated no differences between groups. ADM presented higher RD compared to FGG in all periods. Mean tissue shrinkage for control and test groups was 12.41 versus 55.7%. TT was inferior for ADM group compared to FGG. Esthetics perception by professional evaluation showed superior results for ADM. Histomorphometric analysis demonstrated higher percentage of cellularity, blood vessels, and epithelial luminal to basal surface ratio for FGG group. ADM group presented higher percentage of collagen fibers and inflammatory infiltrate. CONCLUSIONS Both treatments resulted in improvement of clinical parameters, except for RD. ADM group presented more tissue shrinkage and delayed healing, confirmed histologically, but superior professional esthetic perception. CLINICAL RELEVANCE This study added important clinical and histological data to contribute in the decision-making process between indication of FGG or ADM.

Abstract
PURPOSE This animal study investigated vertical bone formation (VBF) around implants and used histomorphometric analysis to compare different bone-filling materials associated with a massive titanium dome as a tissue barrier. MATERIALS AND METHODS Seven dogs were submitted to surgical procedures with extraoral access to the lower edge of the mandible, and four implants were semi-inserted in each animal. Each implant received one treatment: autogenous bone with clot (AB), control clot (C), synthetic graft (Biogran [BG]), or xenograft (Bio-Oss [BO]). Massive titanium domes were stabilized over the implants. Histologic analysis was performed after 3 months, and quantitative aspects were evaluated in extraosseous and intraosseous threads on Image Pro-Plus software. RESULTS VBF around implants exhibited significant values in AB compared with other groups. BG and BO presented statistical equivalency to AB and C in the apposition and filling of extraosseous threads. There was no difference between groups for parameters evaluated in intraosseous threads. CONCLUSION The experimental model was valid for evaluation of VBF around implants placed in atrophic mandibles. Considering the limitations of this study, histomorphometric analysis evidenced better outcomes for group AB. Even though groups BG and BO presented worse outcomes than AB, they were slightly better compared with the control group.

Abstract
OBJECTIVE The aim of this study was to compare the effect of root biomodification by lasers, citric acid and antimicrobial photodynamic therapy (aPDT) on viability and proliferation of human gingival fibroblasts (FGH). DESIGN Groups were divided in control (CC - only cells), and root fragments treated by: scaling and root planing (positice control - SC), Er:YAG (ER-60mJ,10pps,10Hz,10s,2940nm), Nd:YAG (ND-0.5W,15Hz,10s,1640nm), antimicrobial photodynamic therapy (PDT-InGaAIP,30mW,45J/cm2,30s,660nm,toluidine blue O), citric acid plus tetracycline (CA). Fibroblasts (6th passage, 2×103) were cultivated in a 24-h conditioned medium by the treated root fragments. Cell viability was measured by MTT test at 24, 48, 72 and 96h. In a second experiment, FGH cells (104) were cultivated on root fragments which received the same treatments. After 24, 48, 72h the number of cells was counted in SEM pictures. In addition, chemical elements were analyzed by energy dispersive spectroscopy (EDS). Data was analyzed by two-way ANOVA (first experiment), repeated measures ANOVA (second experiment) and ANOVA (EDS experiment) tests complemented by Tukey's test (p<0.05). RESULTS ND, PDT and CA promoted higher cell viability (p<0.05). ND and ER groups presented higher number of cells on root surfaces (p<0.05). ER group presented higher calcium and CA group a higher carbon percentages (p<0.05). CONCLUSIONS All treatments but scaling and root planing stimulated fibroblast viability while Er:YAG and Nd:YAG treated root surfaces presented higher number of cells.

Abstract
The aim of this systematic literature review was to evaluate which type of periodontal preventive and therapeutic approaches presents superior outcomes in patients with Down syndrome (DS). Studies reporting different methods of periodontal care from DS patients were considered eligible. Included clinical studies should indicate at least two periodontal parameters in different periods of assessment. Screening of the articles, data extraction and quality assessment were conducted independently and in duplicate. Electronic search according to the PICO search, with both Key-words and MESH terms were conducted in MEDLINE, EMBASE and CENTRAL databases until March 2016. Manual search was conducted in four journals, namely Journal of Periodontology, Journal of Clinical Periodontology, Journal of Periodontal Research and Special Care in Dentistry and their electronic databases were searched. Electronic and manual search resulted in 763 papers, and of them 744 were excluded after title/abstract assessment. The full text of 19 potentially eligible publications was screened and 9 studies met inclusion criteria. The results demonstrated the importance to introduce youngest DS patients in preventive programs, as well as participation of parents, caregivers or institutional attendants in supervising/performing oral hygiene. In studies with higher frequency of attendance, all age groups presented superior preventive and therapeutic results, irrespective of the therapeutic approach used (surgical/nonsurgical/periodontal care program). The important factors for reducing periodontal parameters were the frequency of the appointments and association with chlorhexidine/plaque disclosing agents as adjuvant treatment. This systematic review demonstrated that early introduction in periodontal care, participation of parents/caregivers/institutional attendants, frequency of attendance and association with chemical adjuvants (independently of the periodontal treatment adopted) seems to improve periodontal outcomes in preventive and periodontal treatment of DS patients. Registration number (Prospero): CRD42016038433.

Abstract
BACKGROUND AND OBJECTIVE Many techniques and flap designs have been used to treat gingival recession by root coverage, but subepithelial connective tissue graft (SCTG) seems to be the gold standard procedure. In an attempt to improve the healing process and increase the success rate of root coverage, some authors have used root modifiers, including different root conditioners, lasers, EMD, recombinant human growth factors and platelet-rich plasma (PRP). The aim of this systematic review was to evaluate the effects of root biomodification in clinical outcomes of gingival recessions treated with SCTG. MATERIAL AND METHODS Studies reporting SCTG associated with any form of root surface biomodification for root coverage of gingival recessions (Miller Class I and Class II) were considered as eligible for inclusion. Studies needed to have data of clinical outcomes in a follow up of at least 6 months. Screening of the articles, data extraction and quality assessment were conducted independently and in duplicate. RESULTS None of the products evaluated (citric acid, EDTA, PRP, lasers and EMD) showed evident benefits in clinical outcomes. Test and control groups presented similar outcomes related to root coverage and periodontal parameters, with no statistical differences between them. The exception was root biomodification with the neodymium-doped yttrium aluminium garnet (Nd:YAG) laser, which impaired root coverage and had a detrimental effect on clinical outcomes. CONCLUSION Based on the present clinical data, the use of root surface modifiers to improve clinical outcomes in gingival recessions treated with SCTG is not justified. More in vivo studies, and randomized clinical trials with larger sample sizes and extended follow up, are necessary.

Abstract
Background This split-mouth, double-blind randomized controlled trial evaluated radiographic changes in infrabony defects treated with open flap debridement (OFD) or OFD associated with enamel matrix derivative (EMD) after a 24–month follow-up. The radiographic distance from the CEJ to the bottom of the defect (BD) was considered the primary outcome. CEJ-BC and defect angle were secondary outcomes. Methods Ten patients presenting 2 or more defects were selected. An individualized film holder was used to take standardized radiographs of the 43 defects, at baseline and after 24 months. Images were digitized and used to measure the distances from the cemento-enamel junction (CEJ) to the alveolar crest (AC), CEJ to the bottom of the defect (BD) and infrabony defect angle. Statistical analysis was performed in SPSS for Windows (version 5.2). Paired samples t test was used to compare test and control groups and to evaluate changes within each group. The level of significance was set at α = 0.05%. Results After 24 months, a significant crestal bone loss was observed for EMD (1.01 mm; p = 0.049) but not for OFD (0.14 mm; p = 0.622). However, no differences were detected between groups (p = 0.37). Reduction of the bone defect depth was significant for OFD (0.70 mm; p = 0.005) but not for EMD (0.04 mm; p = 0.86), while no differences were detected between them (p = 0.87). Both EMD (0.69°; p = 0.82) and OFD (5.71°; p = 0.24) showed an improvement in defect angle measurements but no significant differences were observed after 24 months or between the groups (p = 0.35). Conclusion Linear radiographic analysis was not able to demonstrate superiority of EMD treated infrabony defects when compared to ODF after 24 months. Trial registration ClinicalTrials.gov: NCT02195765. Registered 17 July 2014.
