[PMID: 37118334 DOI: 10.1007/s00784-023-05029-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2022] [Accepted: 04/17/2023] [Indexed: 04/30/2023]
Abstract
OBJECTIVE The aim of this clinical study was to compare the partially de-epithelialized free gingival grafts (d-FGGs) with the conventional free gingival grafts (FGGs) aesthetically using photographic analysis and Visual Analogue Scale (VAS). MATERIALS AND METHODS A total of 30 defects were treated in 15 patients with attached gingiva insufficiency. In the split-mouth study, d-FGGs were applied on one side (test group), while FGGs were applied on the contralateral side (control group). Results of clinical periodontal parameters were evaluated in 6-month follow-up, and aesthetic evaluation results were evaluated in 1-, 3-, and 6-month follow-ups. RESULTS Among the periodontal clinical parameters examined, only the keratinized tissue (KT) width was found to be statistically significantly higher in the test group compared to the control group. In the photo analysis evaluation, the ΔE value at the 3rd month was statistically significantly higher in the test group. In VAS evaluation, there was no significant difference between the two groups in the time periods examined. CONCLUSION Photo analysis is an objective, sensitive, reproducible, and safe method that can be used in dentistry and medicine by detecting the slightest changes and giving more detailed and superior results than visual evaluation. The d-FGG application could provide acceptable aesthetic results by providing an appearance compatible with the gingival contour and gingiva in the adjacent region in creating keratinized gingiva. CLINICAL RELEVANCE While the free gingival graft has color differences with the recipient area, the deep-thelialized gingival graft has a compatible appearance with the recipient area. Partially, de-epithelialized free gingival graft is a method with acceptable aesthetic results. TRIAL REGISTRATION U.S. National Institutes of Health Clinical Trials: NCT04970524.

Abstract
Background Despite many advances in dentistry, no objective and quantitative method is available to evaluate gingival shape. The surface curvature of the optical scans represents an unexploited possibility. The present study aimed to test surface curvature estimation of intraoral scans for objective evaluation of gingival shape. Methods The method consists of four main steps, i.e., optical scanning, surface curvature estimation, region of interest (ROI) definition, and gingival shape analysis. Six different curvature measures and three different diameters were tested for surface curvature estimation on central (n = 78) and interdental ROI (n = 88) of patients with advanced periodontitis to quantify gingiva with a novel gingival shape parameter (GS). The reproducibility was evaluated by repeating the method on two consecutive intraoral scans obtained with a scan-rescan process of the same patient at the same time point (n = 8). Results Minimum and mean curvature measures computed at 2 mm diameter seem optimal GS to quantify shape at central and interdental ROI, respectively. The mean (and standard deviation) of the GS was 0.33 ± 0.07 and 0.19 ± 0.09 for central ROI using minimum, and interdental ROI using mean curvature measure, respectively, computed at a diameter of 2 mm. The method’s reproducibility evaluated on scan-rescan models for the above-mentioned ROI and curvature measures was 0.02 and 0.01, respectively. Conclusions Surface curvature estimation of the intraoral optical scans presents a precise and highly reproducible method for the objective gingival shape quantification enabling the detection of subtle changes. A careful selection of parameters for surface curvature estimation and curvature measures is required.

Abstract
Objective To investigate and compare the various restorative and prosthetic parameters affecting peri-implant tissues’ health following dental implant placement and functional loading. Methods A total of 484 dental implants (length>6mm, non-turned, 2–3 piece, titanium – Straumann) were evaluated for patients (male=271; female=213). Study variables such as patient’s age, gender, implant restoration/crown type, crown retention, and implant crown status were assessed against various periodontal parameters (periodontal pocket depth (PPD), plaque index (PI), bleeding on probing (BOP), gingival color, and crestal bone level). All the data were analyzed using the SPSS software. Results Out of all the investigated dental implants, 201 (42%) of the implants investigated presented with BOP > one-site of the peri-implant mucosa (peri-implant mucositis), 115 (23.76%) presented with peri-implant marginal bone loss. PPD value was significantly lower in good crown status (p<0.0001). Majority of the patients with good crown status had no plaque accumulation based on the PI scores (52.7%). Only 35% of the patients whose crown status was good were having BOP when compared with 65% who did not have any BOP recorded. Gingival color (pale pink and red) showed statistically significant association with crown type (porcelain fused to metal v/s all ceramic) (p=0.005). Most of patients with crown status good had no change in their radiographic findings (94%) compared to only 6% who had implant threads exposed (p<0.0001). Conclusion Optimal design of Implant prosthetic factors are vital for avoiding the development of peri-implant mucositis/peri-implantitis and must be considered during treatment planning while restoring dental implants.

Quantitative Assessment of Gingival Inflammation in Patients Undergoing Nonsurgical Periodontal Therapy Using Photometric CIELab Analysis. BIOMED RESEARCH INTERNATIONAL 2021. [DOI: 10.1155/2021/6615603] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 02/05/2023]
Abstract
Visual inspection and gingival indices have been traditionally used for diagnosis of gingival inflammation. These methods are prone for subjective variability. Thus, the study is aimed at evaluating gingival inflammation quantitatively by using CIELab colour space value obtained from digital photographs. An experimental study was conducted with 27 patients each in group A (gingivitis) and group B (chronic periodontitis, CP). Preoperative and postoperative (1 month) photographs of maxillary anterior sextant were recorded to evaluate CIELab coordinate values. Simultaneously, clinical parameters such as bleeding on probing (BOP) and periodontal probing depth (PPD) along with indices such as plaque index (PI), gingival index (GI), and sulcus bleeding index (SBI) were evaluated before and after the nonsurgical periodontal therapy. Data was presented as the
, and a paired
-test was used for the testing hypothesis with
considered as significant. Data analysis was carried out with Statistical Package for the Social Sciences (SPSS) version 21. A significant reduction (
) is seen in all the clinical parameters and indices before and after the intervention in chronic periodontitis patients. Similar results were seen in gingivitis patients (
) except for PPD. A significant (
) reduction in postoperative values of the
and
coordinates was seen in CP patients; whereas, only the
coordinate value reported a significant (
) reduction in the gingivitis group of patients. The
of the gingivitis and chronic periodontitis groups was 2.25 and 2.96, respectively. Within the confinements of the study, estimating the gingival colour with the help of CIELab values taken via digital photographs can be an excellent valuable tool to assess the gingival colour as a sign of gingival inflammation.

Abstract
Background In the dentistry field, the analysis of dental plaque is vital because it is the main etiological factor in the 2 most prevalent oral diseases: caries and periodontitis. In most of the papers published in the dental literature, the quantification of dental plaque is carried out using traditional, non-automated, and time-consuming indices. Therefore, the development of an automated plaque quantification tool would be of great value to clinicians and researchers. Objective This study aimed to develop a web-based tool called DenTiUS and various clinical indices to evaluate dental plaque levels using image analysis techniques. Methods The tool was executed as a web-based application to facilitate its use by researchers. Expert users are free to define experiments, including images from either a single patient (to observe an individual plaque growth pattern) or several patients (to perform a group characterization) at a particular moment or over time. A novel approach for detecting visible plaque has been developed as well as a new concept known as nonvisible plaque. This new term implies the classification of the remaining dental area into 3 subregions according to the risk of accumulating plaque in the near future. New metrics have also been created to describe visible and nonvisible plaque levels. Results The system generates results tables of the quantitative analysis with absolute averages obtained in each image (indices about visible plaque) and relative measurements (indices about visible and nonvisible plaque) relating to the reference moment. The clinical indices that can be calculated are the following: plaque index of an area per intensity (API index, a value between 0 and 100), area growth index (growth rate of plaque per unit of time in hours; percentage area/hour), and area time index (the time in days needed to achieve a plaque area of 100% concerning the initial area at the same moment). Images and graphics can be obtained for a moment from a patient in addition to a full report presenting all the processing data. Dentistry experts evaluated the DenTiUS Plaque software through a usability test, with the best-scoring questions those related to the workflow efficiency, value of the online help, attractiveness of the user interface, and overall satisfaction. Conclusions The DenTiUS Plaque software allows automatic, reliable, and repeatable quantification of dental plaque levels, providing information about area, intensity, and growth pattern. Dentistry experts recognized that this software is suitable for quantification of dental plaque levels. Consequently, its application in the analysis of plaque evolution patterns associated with different oral conditions, as well as to evaluate the effectiveness of various oral hygiene measures, can represent an improvement in the clinical setting and the methodological quality of research studies.

Effects of stabilized stannous fluoride dentifrice on dental calculus, dental plaque, gingivitis, halitosis and stain: A systematic review. Heliyon 2019; 5:e02850. [PMID: 31872105 PMCID: PMC6909063 DOI: 10.1016/j.heliyon.2019.e02850] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2019] [Revised: 07/23/2019] [Accepted: 11/08/2019] [Indexed: 01/08/2023] Open
Abstract
Objectives The aim of the present systematic review was to examine the scientific evidence for the efficacy of stabilized stannous fluoride (SnF2) dentifrice in relation to dental calculus, dental plaque, gingivitis, halitosis and staining. Data and sources Medline OVID, Embase.com, and the Cochrane Library were searched from database inception until June 2017. Six researchers independently selected studies, extracted data, and assessed methodological quality. A meta-analysis of the 6-month gingivitis studies was done. Risk of bias was estimated using a checklist from the Swedish Agency for Health Technology Assessment (SBU, 2018). Study selection Two studies on dental calculus, 21 on dental plaque and gingivitis, 4 on halitosis, and 5 on stain met the inclusion criteria. Risk of bias was high for the studies on dental calculus, halitosis, and stain, and varied for the dental plaque and gingivitis studies. Significant reductions in dental calculus and in halitosis were reported for the SnF2 dentifrice; no differences in stain reduction were noted. A meta-analysis on gingivitis found better results for the SnF2 dentifrice compared to other dentifrices, though the results of the individual trials in the meta-analyses showed a substantial heterogeneity. Conclusions The present review found that stabilized SnF2 toothpaste had a positive effect on the reduction of dental calculus build-up, dental plaque, gingivitis, stain and halitosis. A tendency towards a more pronounced effect than using toothpastes not containing SnF2 was found. However, a new generation of well conducted randomized trials are needed to further support these findings. Clinical relevance Adding a SnF2 toothpaste to the daily oral care routine is an easy strategy that may have multiple oral health benefits.

Abstract
OBJECTIVE Clinical gingival inflammation is a well-defined site-specific condition for which several measurement systems have been proposed and validated, and epidemiological studies consistently indicate its high prevalence globally. However, it is clear that defining and grading a gingival inflammatory condition at a site level (i.e. a "gingivitis site") is completely different from defining and grading a "gingivitis case" (GC) (i.e. a patient affected by gingivitis), and that a "gingivitis site" does not necessarily mean a "GC". The purpose of the present review is to summarize the evidence on clinical, biochemical, microbiologic, genetic markers as well as symptoms associated with plaque-induced gingivitis and to propose a set of criteria to define GC. IMPORTANCE A universally accepted case definition for gingivitis would provide the necessary information to enable oral health professionals to assess the effectiveness of their prevention strategies and treatment regimens; help set priorities for therapeutic actions/programs by health care providers; and undertake surveillance. FINDINGS Based on available methods to assess gingival inflammation, GC could be simply, objectively and accurately identified and graded using bleeding on probing score (BOP%) CONCLUSIONS: A patient with intact periodontium would be diagnosed as a GC according to a BOP score ≥ 10%, further classified as localized (BOP score ≥ 10% and ≤30%) or generalized (BOP score > 30%). The proposed classification may also apply to patients with a reduced periodontium, where a GC would characterize a patient with attachment loss and BOP score ≥ 10%, but without BOP in any site probing ≥4 mm in depth.

Abstract
AIM The aim of this study was to compare the translucency parameter (TP) of ultratranslucent multilayered (UTML) zirconia according to thickness and layer level. MATERIALS AND METHODS Rectangles of UTML zirconia with four layers [dentin layer (DEL), first transitional layer (FTL), second transitional layer (STL), and enamel layer (ENL)] and four different thicknesses (0.4, 0.6, 0.8, and 1 mm) were milled from blanks. Digital images were taken in a dark studio against white and black backgrounds under simulated daylight illumination and international commission on illumination (CIE) Lab* color values recorded using Photoshop Creative Cloud software. The TP was computed and compared according to thickness and layer level using analysis of variance (ANOVA) followed by Bonferroni post hoc analysis for multiple comparisons. Significance was set at p < 0.05. RESULTS In each thickness, TP values were similar between any two layers. The significant effect of thickness on the TP was observed only in the first two layers. In the DEL, translucency was significantly greater at 0.4 mm than all other thicknesses. In the FTL, differences were significant between 0.4 and 0.8 mm and between 0.4 and 1 mm. CONCLUSION The investigated zirconia does not seem to show gradational changes in relative translucency from dentin to enamel levels regardless of the thickness used. Thickness affected the TP only in the first two layers with better translu-cency at 0.4 mm. CLINICAL SIGNIFICANCE Since relative translucency does not seem to be significantly different between layers, clinicians can modify the apicocoronal positioning of the UTML layers within the restoration according to the desired Chroma without any implications on the clinically perceived translucency. While the thickness of 0.4 mm may be suggested for anterior esthetic veneers because of its higher translucency, the other thicknesses of 0.6 to 1 mm can be used to mask colored abutments in full contour restorations.

Abstract
OBJECTIVES The hypothesis to be tested was that using the SOPROCARE system in fluorescence perio-mode allows scoring of microbial plaque that is comparable to the Turesky modification of the Quigley Hein plaque index (T-QH) and scoring of gingival inflammation comparable to the Silness and Löe gingival inflammation index (GI). MATERIALS AND METHODS Fifty-five subjects with various amounts of microbial plaque were recruited. The T-QH and GI index were recorded. SOPROCARE pictures were recorded in fluorescence perio-mode and in daylight mode. Finally, conventional digital photographs were taken. All pictures were assessed using the same criteria as described for the clinical indices. RESULTS The average T-QH was 1.1 ± 1.2 (mean ± SD). Scoring with SOPROCARE perio-mode led to a slightly higher average than the T-QH scores. SOPROCARE daylight mode and digital photography showed the highest plaque scores. The average GI index was 0.7 ± 0.9. SOPROCARE in perio-mode scored slightly lower. Linear regression fits between the different clinical indices and SOPROCARE scores were significantly different from zero demonstrating high goodness of fit. CONCLUSIONS The study demonstrated that the SOPROCARE fluorescence assessment tool in perio-mode allows reliable judgment of microbial plaque and gingival inflammation levels similar to the established Turesky-modified Quigley Hein index and the Silness and Löe gingival inflammation index. Training on plaque-free teeth will actually reduce scoring errors. CLINICAL RELEVANCE The SOPROCARE fluorescence tool in perio-mode provides reliable evaluation of microbial plaque and gingival inflammation for the dental clinician.

Abstract
Background: Gingival inflammation may be caused by injury or plaque-related disease and reduction in inflammation can be a useful indicator of gingival recovery. There has been little research on development of non-index method to measure gingival condition. The study aimed to investigate the quantitative analysis of gingival swelling and color characteristics of gingiva by digital images before and after treatment of individual patients. Material and Methods: Twenty volunteers with gingival inflammation were recruited and digital images were taken. Duplicate measurements were made on the first visit by the same examiner. At a subsequent visit (1 month) following scaling and root planing, second images were taken. Gingival changes were determined by assessing redness and tooth surface area visible between the level of the inter-proximal papillae and the gingival margin. Results: Significant difference was found between the pre-operative and post-operative photographs with regard to swelling and gingival redness. Conclusion: Thus this method aids in quantitative analysis of swelling and color characteristics of gingiva by digital images may become a valuable, objective, practicable non-index and inexpensive evaluation procedure of gingival inflammation.

[PMID: 21724067 DOI: 10.1016/j.ajodo.2010.12.016] [Citation(s) in RCA: 119] [Impact Index Per Article: 9.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2010] [Revised: 12/01/2010] [Accepted: 12/01/2010] [Indexed: 10/14/2022]
Abstract
INTRODUCTION White-spot lesions (WSL) are one of the most undesired side effects of multibracket appliance treatment (MB). The aim of this study was to investigate the incidence and further course of WSL during and after MB. METHODS Four hundred patients (168 boys, 232 girls) meeting the inclusion criteria--all maxillary front teeth fully erupted and visible before treatment, no fillings or structural abnormalities, MB duration of at least 1 year, and retention period of at least 1 year--were selected. The patients' average age was 13.7 years (SD, 3.5), and the average MB time was 1.9 years (SD, 3.6). All patients received standardized general prophylactic instructions. A modification of the WSL index was used to evaluate the 4 maxillary front teeth on introral photos before and after treatment, and after retention. RESULTS Before treatment, 32.3% of the patients had WSL. After MB, 73.5% of the patients presented WSL. The incidence of WSL during MB was 60.9% of the patients. After treatment, most patients (63.3%) had mild lesions, but the remaining were affected severely with (26.9%) and without (9.9%) cavitations. Only 26% of the patients were free of WSL all the time. After the retention phase, most (57.1%) of the WSL patients after treatment showed improvement, 26% remained unchanged, and 16.7% deteriorated. Male WSL patients tended to show more severe WSL than did the girls. There was a tendency for increased WSL development during the adolescent years compared with the preadolescent and postadolescent age groups. CONCLUSIONS With only standardized general prophylactic measures, new WSL developing on the maxillary front teeth during MB remain a frequent undesired side effect, affecting 60.9% of patients and counteracting our efforts for clinical excellence.
