ABSTRACT
BACKGROUND: Papacarie pre-treatment of dentin surface has been reported to exhibit good bond strength values between dentin and composites. Its desirable properties like high pH, sites specify and anti-inflammatory response makes it a future material in place acid etching pre-treatment. Acid etching may cause sensitivity and collapse of dentinal matrix. METHODS: This in-vitro study involved, 60 caries free extracted premolars, randomly divided into three groups. Control Group (Group A) No pre-treatment of dentin prior adhesive application. Experimental Group B acid etchant was applied before adhesive application. Experimental Group C Papacarie was used as a pre-treatment agent. All these specimens were tested for shear bond strength with the help of Universal Testing Machine. All the collected data was entered in SPSS version 20.0. ANOVA was used to determine the mean SBS (Shear Bond strength) values of control and experimental groups. RESULTS: The mean shear bond strength of material was 7.74±0.47 in group A, 17.80±1.43 in group B and 15.11±0.70 in group C. Group B showing better strength than other two groups. CONCLUSIONS: The study provides information about longevity of composite restorations and may help in extending the clinical usage of papacarie to avoid harmful effects of acid etching on dentin and pulpal tissue.

OBJECTIVES: To assess knowledge, awareness, and practice of health care workers about the role of teledentistry in coronavirus disease 2019 (COVID-19). MATERIALS AND METHODS: A prevalidated structured questionnaire was used to evaluate awareness of general dentists, postgraduate dental students, dental educators, and consultants with postgraduation degrees toward teledentistry. The acceptability, reliability, and language clarity were also pretested. A total of 510 dental professionals contributed to this study. STATISTICAL ANALYSIS: A statistical analysis using SPSS (version 20.0) was performed. Responses were noted as yes or no. A p-value of ≤ 0.05 was considered to be significant. Frequencies described data. Chi-square test was performed for intergroup comparison to evaluate if the knowledge and attitude diverge with the increase in the level of seniority in the profession. RESULTS: Awareness regarding teledentistry is high among general dentists with bachelor of dental surgery qualification in comparison to final-year students and postgraduate dental students. The majority of participants agreed with improvement in health care (88.20%), access to rural areas (82.90%), and general practicing dentist agreed with statistically significant difference (0.00) on saving time by teledentistry. CONCLUSION: General practicing dentist was observed with high awareness of teledentistry as compared with postgraduate and undergraduate dental students.
