This study assessed the efficacy of five denture cleansers on the microbial adherence and surface topography of conventional and CAD/CAM denture base resins. Acrylic resin discs were fabricated using conventional, milling, and 3D printing methods (N = 180). The discs were contaminated with dual species of Candida albicans and Streptococcus mutans biofilm for 72 h and then disinfected with either of the denture cleansers (Fittydent cleansing tablets, 2% Chlorhexidine gluconate, 0.2% Chlorhexidine gluconate, 0.5% sodium hypochlorite, and 1% sodium hypochlorite (n = 10). Distilled water served as the control group. The colony-forming units of the microorganisms were calculated, followed by post-treatment surface roughness. Data were statistically analyzed using one-way ANOVA, paired t-test, and post hoc Tukey HSD test (α = 0.05). Among the denture cleansers, 2% Chlorhexidine gluconate, 0.5% sodium hypochlorite, and 1% sodium hypochlorite had the best cleansing effect on the resin discs and demonstrated zero growth of colonies for both the species. Comparing the material groups, the 3D-processed discs showed higher colony-forming units followed by the conventional and CAD/CAM milled group. The highest surface roughness was demonstrated by the 3D-printed discs (0.690 ± 0.08 μm), followed by the conventional (0.493 ± 0.11 μm) and the milled groups (0.301 ± 0.08 μm). The tested chemical denture cleansers affected the Candida albicans and Streptococcus mutans adhesion compared to control discs immersed in distilled water. The clinician may recommend to their patient to use 2% chlorhexidine gluconate for the disinfection of CAD/CAM PMMA denture base materials.

Objective The aim of this study is to investigate the public’s attitudes and knowledge toward chairside dental screening and laboratory investigations based on demographic data. Methods A self-administered structured questionnaire regarding chairside screening was designed employing a 5-point Likert-type scale. The questionnaire was distributed to among sample of adults. Data were collected and statistically analyzed using descriptive statistics, t -tests, ANOVA, and P values. Results A total of 573 questionnaires were completed. Most respondents were willing to have a dentist conduct screening for diseases, in particular blood measurement (89%), hypertension (85.7%) and lab result discussion (83.1%), having medical condition did not affect the willingness. The lowest reported willingness was to undergo biopsy (54%) and hepatitis screening (67.6%) Age, education, hospital, and prior chairside screening were found to be significant factors for willingness. Conclusion The population’s willingness to undergo chairside medical screenings in the dental office is crucial for the implementation of this strategy and to deliver a holistic approach to treating patients’ medical conditions.

Background: Controversy exists in the literature regarding the most optimal repair procedure for improving the adhesion between the repair resin and the existing resin composite materials. Hence the aim of the present study was to do a systematic review and to analyze the adhesion potential of resin-based composites to similar and dissimilar composites and aimed to determine the possible dominant factors affecting the bond strength results. Materials & Methods: Randomized clinical trials (RCTs) and prospective cohort design were searched through electronic databases including MEDLINE, PubMed, Web of Science, and the Cochrane Central Register of Controlled Trials for randomized clinical trials (RCTs) until July 2020 that compared different methods of composite restoration repair and a minimum mean follow-up time of 1 year. There were no restrictions on a particular treatment indication or outcome measures. Two authors independently conducted screening, risk of bias assessment, and data extraction of eligible trials in duplicate. We applied the Cochrane risk of bias assessment tool to consider the risk of bias. Results: We identified 10 articles; two of them were RCTs, and eight prospective cohort studies. There were 530 participants, with 990 teeth, dealing with resin-based composite (RBC) restorations. The intervention of defective restorations ranged from minimal intervention to total restoration replacement. The evaluation criteria were also varied with different evaluation protocols. The low number and heterogeneity of RCTs did not allow for meta-analyses. Conclusions: Although different repair protocols are mentioned in the literature according to the included studies, an appropriate and definitive conclusion can't be drawn. However, it seems repairs versus replacements should be considered as the first line of treatment when all factors lead to repair rather than replacement. Further randomized controlled trials with high methodological quality need to be conducted in order to establish evidence-based recommendations, particularly for RBC repair.

Objective To evaluate the patient’s willingness to declare their medical history to their dentists against demographic and medical information. Methods A self-administered structured questionnaire regarding common chronic condition and pregnancy awareness and attitude toward medical information disclosure to their dentists was designed employing a five-point Likert-type scale. The questionnaire was distributed to among sample of adults. Data were collected and statistically analyzed using descriptive statistics, t -tests, ANOVA, and P values. Results A total of 573 questionnaires were completed. Only 61.3% were willing to share their medical history with the dentist and 76.1% will disclose previous complications of their condition in the dental office. Two third 71.9%of the sample will disclose about medications and 76.1% will disclose pregnancy month. There was lack of education regarding health conditions, 73.3% did not receive any information about their medications. While 72.8% did not receive any information regarding complications of their disease and 76.3% were not told what to do if complication arises. Conclusion The population’s willingness to reveal their medical information in the dental office is crucial. Though was within acceptable limit but still deficient. Age, education, occupation and marital status have a significant effect on disclosing and awareness. Educating patients and raising their awareness may aid in reducing emergencies, errors, and legal issues in the dental office.
