Objectives This cross-sectional study assessed the oral health status of attendees and residents in United Arab Emirates (UAE) care homes. Materials and Methods All care homes identified from the UAE Ministry of Health website were selected and all attendees or residents included. Medical conditions were classified according to World Health Organization (WHO) criteria. Oral and dental status was recorded on the WHO Oral Health Assessment form for adults and demographic details were recorded separately. The three examiners had training and calibration exercises before conducting the dental examinations with an overall mean inter-examiner κ of 0.67. Results A total of 107 patients participated in the study with a mean age of 67.5 years (standard deviation [SD] = 15.65 years). The mean age of men (n = 57) (69.2 years, SD = 16.3) was not significantly different to the mean age of women (65.5 years, SD = 14.8, P > 0.05). The American Society of Anaesthesiologists (ASA) classification of mild disease was present inre home residents/attendees. Carers require training in oral health as dental care is a priority for this group.

TMJ conditions have many different etiologies, appearances, and relevant clinical significance. Objective The objective of this study was to evaluate the concordance of the diagnosis of degenerative changes in the TMJ in panoramic radiographs. Materials and Methods Cone beam computed tomography (CBCT) was used as a reference standard. Images of 84 patients (168 TMJs), 61 females (72.6%) and 23 males (27.4%) with an average age of 47.4 years, were evaluated by three radiologists who established the presence or absence of degenerative changes in the jaw heads. The data were collected and organized in a spreadsheet. Concordance between evaluators was analyzed using agreement percentages, statistical κ, and confidence intervals. see more In the analysis of compliance with CBCT, sensitivity, specificity, predictive positive and negative values, and probabilities of false positives and negatives were also calculated. All inferential tests were performed with a 5% significance level. Results The percentage of agreement among raters in panoramic radiographs ranged from 66.7% to 82.9%, considered mild to moderate. Correlation between radiographic and tomographic images ranged from 45.5% to 64.9% in the inter-evaluator reviews, representing a very mild agreement. Sensitivity ranged from 28.6% to 58.7% and specificity from 66.7% to 100.0%. Positive predictive value ranged from 77.1% to 100.0%; the negative predictive value was lower, ranging from 32.2% to 54.8%. The probability of false negatives was higher than that of false positives, ranging from 45.2% to 67.8%. Conclusion The rater did not reach acceptable diagnosis levels.

Materials and Methods Ten photographs were digitally manipulated involving three facial, two smile, four dental, and one gingival components. Fifty images were randomized and rated according to attractiveness by two groups dental students which subdivided into preclinical students and clinical students, and laypersons. The participants evaluated the original and manipulated images using a visual analog scale. The responses were then analyzed using Mann-Whitney U test. Results The results showed threshold levels of noticeable differences between varying levels of discrepancy. The overall perception of aesthetics was high among dental clinical students with the highest perception toward facial profile and the lowest toward gingival margin height. Of the respondents, no differences were found in the perception between male and female participants. Dental students perceived aesthetic components more accurately than laypersons. Conclusion Dental students group had a better perception of dentofacial aesthetics than included laypersons. Unlike gender, clinical training has a substantial positive effect on the assessment of beauty. Dental students sub divided into dental preclinical students and dental clinical students (clinical training is a variable of all subgroups).

Dental anxiety (being the fear of unknown in a dental setting) would definitely have a substantial effect on the children with visual impairment. Assessment of the dental anxiety makes it possible to design intervention programs aimed at reducing the anxiety levels in children with visual impairment. Thus, the aim of this study was to assess the dental anxiety levels before and after dental visit in children with visual impairment using Modified Dental Anxiety Scale (MDAS) printed in braille. Materials and Methods A total of 144 institutionalized children with visual impairment in the age group of 6-13 years, residing at an institutionalized blind school, participated in the study. Dental anxiety was assessed pre- and post-dental-screening visit using MDAS printed in braille. Statistical analysis was performed using the Wilcoxon matched-pairs signed rank test. Results Of 144 children, just before dental screening visit, 78 (54.1%) had severe dental anxiety, 52 (36.11%) had mild anxiety, and 14(9.72%) reported no anxiety, whereas after dental education, only 28 (19.44%) had severe anxiety, 22 (16.66%) had mild anxiety, and 94 (63.88%) reported no anxiety. Conclusion In our study, there was a significant decrease in dental anxiety after dental screening and education. Therefore, proper behavior management techniques and dental health education programs would decrease dental anxiety in children with visual impairment.
