Influence of examiner calibration on clinical and mri diagnosis of temporomandibular joint disc displacement: a systematic review and meta-analysis.

OBJECTIVES: This study aimed to verify the accuracy of clinical protocols for the diagnosis of disc displacement (DD) compared with magnetic resonance imaging (MRI), considering examiners' calibration. METHODS: PubMed, Cochrane (Central), Scopus, Web of Science, LILACS, Embase, Science Direct, Google Scholar, and DANS EASY Archive databases were searched. Two reviewers independently screened and selected the studies. A meta-analysis was conducted using the R Statistical software. Results are shown using sensitivity and specificity, and 95% confidence intervals. RESULTS: Of the 20 studies included in the systematic review, only 3 were classified as low risk of bias. Seventeen studies were included in the meta-analysis. Compared to MRI, clinical protocols showed overall sensitivity and specificity of 0.75 (0.63-0.83) and 0.73 (0.59-0.84) for DD diagnosis, respectively. For DD with reduction, sensitivity was 0.64 (0.48-0.77) and specificity was 0.72 (0.48-0.87). For DD without reduction, sensitivity was 0.58 (0.39-0.74) and specificity 0.93 (0.83-0.97). Only 8 studies reported examiner calibration when performing clinical and/or MRI evaluation; nevertheless, calibration showed a tendency to improve the diagnosis of DD. CONCLUSION: The sensitivity and specificity of clinical protocols in the diagnosis of DD are slightly below the recommended values, as well as the studies lack calibration of clinical and MRI examiners. Examiner calibration seems to improve the diagnosis of DD.

Autistic individuals have worse oral status than neurotypical controls: a systematic review and meta-analysis of observational studies.

OBJECTIVE: To compare dental caries, oral hygiene, periodontal status, bruxism, malocclusion, tooth loss, and salivary alterations between autistic and typical developing individuals. MATERIAL AND METHODS: Observational studies presenting clinical measures of oral outcomes between autism spectrum disorder (ASD) individuals and controls. EMBASE, LILACS, PubMed, PsycINFO, Scopus, Web of Science, Google Scholar, and ProQuest were searched up to June 26, 2023. Pairs of reviewers independently conducted study selection, data extraction, and assessments of methodological quality and certainty of evidence. Meta-analyses of standardized mean differences (SMD) and risk ratio (RR) were performed. RESULTS: A total of 47 studies comprising 6885 autistic individuals were included in the review. Autistic individuals had significantly higher severity of dental-caries experience in primary teeth (SMD 0.29, 95%CI 0.02, 0.56), of dental plaque presence (SMD 0.59, 95%CI 0.24, 0.94), and of gingivitis (SMD 0.45, 95%CI 0.02, 0.88). Autistic individuals showed higher probability of occurrence of gingivitis (RR 1.34, 95%CI 1.08, 1.66,), bruxism (RR 4.23, 95%CI 2.32, 7.74), overjet (RR 2.16, 95%CI 1.28, 3.64), overbite (RR 1.62, 95%CI 1.02, 2.59), crossbite (RR 1.48, 95%CI 1.02, 2.13), and openbite (RR 2.37, 95%CI 1.46, 3.85), when compared to neurotypical individuals. Most estimates showed a small effect size with very low certainty of evidence. CONCLUSION: Autistic individuals show worse oral health status than controls. CLINICAL RELEVANCE: The findings reported herein can help to build health policies to better serve autistic individuals including prevention actions and access to specialized dental care.

Clinical and sociodemographic factors associated with oral health-related quality of life in survivors of head and neck cancer.

BACKGROUND: Factors related to head and neck cancer and the treatment of the disease can affect quality of life. The aim of this study was to determine factors associated with the severity of impact on oral health-related quality of life (OHRQoL) in survivors of head and neck cancer using a multivariate analysis. METHODS: This cross-sectional study evaluated 90 volunteers who had completed radiotherapy at least 3 months earlier. OHRQoL was assessed using oral health impact profile (OHIP-14) and the data were analyzed using robust variance poisson regression models. RESULTS: The mean total OHIP-14 score was 23.98 ± 12.55. Patients with hyposalivation had 56% higher (worse) mean OHIP-14 total scores (CI:1.11-2.18) and patients with advanced stage tumors had 31% higher mean OHIP-14 total scores (CI:1.03-1.66) in multivariate analyses. CONCLUSION: OHRQoL of survivors of head and neck cancer experienced a negative impact following radiotherapy. The impact was associated with hyposalivation and advanced stage tumors.

Periodontitis is associated with oral health-related quality of life in individuals with end-stage renal disease.

AIM: The aim of the present study was to evaluate whether periodontitis is independently associated with oral health-related quality of life (OHRQoL) in individuals with end-stage renal disease (ESRD). MATERIALS AND METHODS: Calibrated examiners assessed 180 adults with ESRD. A full-mouth periodontal examination was performed at six sites on each tooth. Periodontitis was considered a categorical variable (absent, mild/moderate or severe). OHRQoL was assessed using the simplified version of the Oral Health Impact Profile (OHIP14 ) questionnaire. Adjusted multivariate Poisson regression analysis was used with a conceptual hierarchical approach to calculate the rate ratio (RR) of OHIP14 scores for periodontitis according to the severity categories. RESULTS: In the adjusted model, mild/moderate and severe periodontitis were significantly associated with poorer OHRQoL compared to the absence of periodontitis [RR = 1.49 (95% confidence interval: 1.16-1.91) and RR 1.77 (95% CI: 1.36-2.30), respectively]. The adjusted domain-specific analysis revealed that mild/moderate periodontitis significantly impacted the psychological disability domain and severe periodontitis significantly impacted the physical pain, psychological discomfort, physical disability and psychological disability domains. CONCLUSIONS: Periodontitis exerts an influence on OHRQoL in individuals with ESRD, with a more severe condition impacting different domains.

Impact of excessive gingival display on oral health-related quality of life in a Southern Brazilian young population.

AIM: To compare oral health-related quality of life (OHRQoL) between individuals with and without excessive gingival display (EGD). MATERIALS AND METHODS: A cross-sectional study was conducted in 53 individuals with EGD and 53 controls matched for sex and age. The outcome was OHRQoL, determined using the Oral Health Impact Profile (OHIP-14) and self-perceptions of satisfaction with smile aesthetics. A clinical examination was conducted to evaluate the smile line, colour of the teeth, tooth wear and malocclusion. Poisson regression was used to model the association between excessive gingival display and OHRQoL. RESULTS: Participants with EGD had higher total OHIP-14 score (4.81 ± 4.76) in comparison with the controls (1.85 ± 3.77; p < .001). The percentage of satisfied with smile individuals without and with EGD was 78.9% and 21.1%, respectively (p = .005). In the multivariate analysis, total OHIP-14 scores were 2.10-fold higher individuals with EGD, independently of the other variables analysed. Impacts were evident on the functional limitation, psychological discomfort, psychological disability and social handicap. CONCLUSIONS: The occurrence of EGD exerted a negative impact on OHRQoL independently of confounding variables in this specific population. The present findings justify the planning of treatment for individuals with EGD that impacts quality of life.

Association Among Periodontitis and the Use of Crack Cocaine and Other Illicit Drugs.

BACKGROUND: Crack cocaine can alter functions related to the immune system and exert a negative influence on progression and severity of periodontitis. The aim of this study is to compare periodontal status between crack cocaine users and crack cocaine non-users and investigate the association between crack cocaine and periodontitis after adjustments for confounding variables. METHODS: This cross-sectional study evaluated 106 individuals exposed to crack cocaine and 106 never exposed, matched for age, sex, and tobacco use. An examiner determined visible plaque index (VPI), marginal bleeding index, supragingival dental calculus, probing depth (PD), clinical attachment level (CAL), and bleeding on probing (BOP). Logistic regression was used to model associations between crack cocaine and periodontitis (at least three sites with CAL >4 mm and at least two sites with PD >3 mm, not in the same site or tooth). RESULTS: Prevalence of periodontitis among crack non-users and crack users was 20.8% and 43.4%, respectively. Crack users had greater VPI, BOP, PD ≥3 mm, and CAL ≥4 mm than crack non-users. Periodontitis was associated with age >24 years, schooling ≤8 years, smoking, moderate/heavy alcohol use, and plaque rate ≥41%. Crack users had an approximately three-fold greater chance (odds ratio: 3.44; 95% confidence interval: 1.51 to 7.86) of periodontitis than non-users. CONCLUSION: Occurrence of periodontitis, visible plaque, and gingival bleeding was significantly higher among crack users, and crack use was associated with occurrence of periodontitis.

Supragingival plaque removal with and without dentifrice: a randomized controlled clinical trial.

The aim of this study was to compare the efficacy of dental plaque removal by brushing with and without conventional dentifrice. Twenty-four students aged 17 to 28 years participated in this randomized controlled clinical trial. Quadrants 1-3 or 2-4 were randomly allocated to the test group (brushing without dentifrice) or control group (brushing with dentifrice). After 72 h of cessation of oral hygiene, Quigley & Hein (Turesky) plaque index was assessed before and after brushing by a calibrated and blind examiner. Overtime and intergroup comparisons were performed by Student's paired sample t-test at 5% significance level. The results showed that both groups after toothbrushing presented statistically significant reductions in plaque, with no differences between them (from 3.06 ± 0.54 to 1.27 ± 0.26 versus from 3.07 ± 0.52 to 1.31 ± 0.23). A separate analysis of the buccal and lingual aspects also showed no significant differences between groups. It may be concluded that the use of a conventional dentifrice during toothbrushing does not seem to enhance plaque removal capacity.

O objetivo deste estudo foi comparar a eficácia de remoção mecânica da placa dental através da escovação com e sem dentifrício. Vinte e quatro estudantes com idade de 17 a 28 anos participaram deste ensaio clínico randomizado. Os quadrantes 1-3 ou 2-4 foram randomizados para alocação no grupo teste (escovação sem dentifrício) ou grupo controle (escovação com dentifrício). Após 72 h de cessação de higiene bucal, o índice de placa de Quigley & Hein (Turesky) foi avaliado antes e após a escovação por um examinador cego e calibrado. Comparações intra e intergrupo foram realizadas pelo teste t pareado, a um nível de significância de 5%. Os resultados demonstraram que, após a escovação, ambos os grupos apresentaram redução significativa de placa, porém sem diferenças intergrupos (3,06 ± 0,54 a 1,27 ± 0,26 versus 3,07 ± 0,52 a 1,31 ± 0,23). Uma análise separada das faces vestibulares e linguais também não revelou diferenças entre os grupos. Conclui-se que a utilização de dentifrícios associado ao controle mecânico parece não contribuir para a remoção da placa dental.

The effect of 0.12% chlorhexidine gluconate rinsing on previously plaque-free and plaque-covered surfaces: a randomized, controlled clinical trial.

BACKGROUND: Previous in vitro studies showed little bactericidal effect on structured oral biofilm after exposure to chlorhexidine (CHX). In vivo evidence of a CHX effect against structured biofilm is scarce. The purpose of this study was to compare the efficacy of 0.12% CHX gluconate on previously plaque-free and plaque-covered surfaces. METHODS: This study had a single-masked, randomized split-mouth, 21-day experimental gingivitis design including 20 individuals who refrained from all mechanical plaque control methods for 25 days. On day 4 of plaque accumulation, the individuals had two randomized quadrants cleaned; the other two quadrants served as the plaque-covered surfaces. Also, on day 4, the individuals started rinsing with 0.12% CHX gluconate for 21 days. The Quigley and Hein plaque index (PI), gingival index (GI), and gingival crevicular fluid (GCF) volume were assessed at baseline and days 21 and 25. The PI also was assessed at days 4, 11, and 18. RESULTS: Intergroup comparisons showed statistically higher PI throughout the study on the plaque-covered surfaces compared to the plaque-free surfaces. When the inflammatory response over time was analyzed, a statistically greater increase in GI (from 0.21+/-0.02 to 0.93+/-0.03 versus from 0.18+/-0.01 to 0.52+/-0.03 on plaque-covered and plaque-free surfaces, respectively) and GCF volumes (from 48.09 to 94.28 microl versus from 46.94 to 64.99 microl on plaque-covered and plaque-free surfaces, respectively) occurred on plaque-covered surfaces after 21 days of plaque accumulation. CONCLUSIONS: A 0.12% CHX gluconate mouthrinse had little antiplaque and antigingivitis effect on previously plaque-covered surfaces. These results confirm the diminished effect of CHX on structured biofilm and reinforce the necessity of biofilm disruption before the initiation of CHX mouthrinse.
