Background: The recent outbreak of coronavirus (COVID-19) caused a significant impact on dentistry. It is imperative to have sufficient knowledge of COVID-19 to manage patients in the dental operatory. Aim: To assess the knowledge and perceptions of dentists from different specialities about COVID-19 disease. Settings and Design: Cross-sectional online survey. Materials and Methods: This study used a descriptive cross-sectional study design with a self-administered questionnaire. The questionnaire included three sets of 23 questions [Demographic-4; Source of information-1; Knowledge-10 and Perceptions-8]. The comparison of mean scores of knowledge and perceptions were interpreted based on the occupation of dental specialists. Statistical Analysis Used: The association between demographic variables and dental specialists' knowledge and perception scores was carried out using SPSS (Version IBM 21.0, NY, USA). Results: A total of 429 dentists from various specialties participated in the present study. The study had obtained a overall good knowledge score (92.7%) with a mean value of 8.86 + 0.22, and a perception score (70.7%) with a mean value of 5.4+0.3. The present study reports a statistically significant difference between age (p=0.03) and knowledge source (p<0.05). The multi variate regression analysis showed that dentists' specialty had no significant effect on knowledge and perception. Conclusion: The study reports sufficient knowledge and perception scores. Oral maxillofacial surgeons showed higher knowledge scores, while prosthodontics and periodontics achieved good mean scores for perception on COVID-19. Social media and health authorities played an equally important role in the overall knowledge of the source of information related to COVID-19.

Background. Conventional mechanical debridement alone cannot eliminate bacteria and their products from periodontal pockets. Adjunctive therapies improve tissue healing through detoxification and bactericidal effects. Photodynamic therapy (PDT) is a non-invasive treatment procedure that involves the use of a dye as a photosensitizer to attach to the target cell and be activated by a photon of an appropriate wavelength. This study aimed to assess the effectiveness of PDT in treating periodontitis as an adjunct to scaling and root planing. Methods. Fifteen subjects with chronic periodontitis were treated randomly with scaling and root planing (SRP), followed by a single PDT (test) or SRP (control) episode alone. Full-mouth plaque index (PI), sulcus bleeding index (SBI), probing depth (PD), and clinical attachment level (CAL) were assessed at baseline and 1-month and 3-month intervals. Microbiological evaluation of Porphyromonas gingivalis (Pg) in subgingival plaque samples was performed using a commercially available real-time polymerase chain reaction. Results. The results revealed a significant difference in PI, SBI, PD, CAL, and microbiological parameters between the groups one and three months after treatment. Conclusion. A combination of PDT and SRP gave rise to a significant improvement in clinical and microbiological parameters in patients with chronic periodontitis.
