Aim: The aim of this study was to compare push-out bond strength of root canal spaces filled with AH-Plus and BioRoot RCS after using different irrigants. Materials and Methods: Eighty single-rooted teeth were decoronated and endodontically treated by crown-down technique using ProTaper Universal rotary files progressively till F4 (40/0.06). Samples were divided into two groups according to the sealer ( n = 40): Group A = BioRoot RCS, Group B = AH Plus, further subdivided into four subgroups according to irrigation protocol ( n = 10): Group 1A, 1B – 0.9% saline, Group 2A, 2B – 5.25% NaOCl + 17% EDTA, Group 3A, 3B– 17% EDTA +2% chlorhexidine, and Group 4A, 4B – 17% EDTA + 3% green tea extract. Samples were obturated with sealers and prepared for push-out test with root slices of 2 mm thickness using universal testing machine. Data were statistically analyzed using two-way ANOVA, Bonferroni's post hoc analysis, and independent Student's t -test. Results: BioRoot RCS exhibited significantly higher push-out bond strength ( n < 0.001). The interaction between irrigants and sealer showed higher bond strength for BioRoot RCS when 17% EDTA+ green tea was used. Conclusion: Within the limitation of the study, it was concluded that bond strength of a sealer was influenced by the irrigants used.

Periodontally accelerated osteogenic orthodontics (PAOO), also known as Wilckodontics, is a clinical procedure that combines corticotomy (a surgical technique in which the bone is cut, perforated, or mechanically altered), particulate bone grafting, and orthodontic force application. By this procedure, the teeth can be made to move through the bone rapidly by means of harnessing and stimulating the innate potential of the bone and utilizing tissue engineering principles. Once the tooth movement gets completed, bone rebuilds around the tooth, thereby reducing the time of orthodontic treatment from years to months. This article aims to present a comprehensive review about PAOO or Wilckodontics.

On 11 March 2020, the World Health Organization (WHO) declared the novel coronavirus (COVID-19) outbreak a global pandemic. Knowledge about COVID-19 is an important determinant towards successful disease control. This study was designed to elucidate the knowledge, attitudes and practices (KAP) and mental health status regarding COVID-19 amongst trainees of two institutes in the state of Uttar Pradesh, India. The cross-sectional study was conducted from January to March 2021. A bilingual survey recorded the responses of 400 participants from the institutes. Variables, such as sex, age, marital status, occupation, level of education, number of family members and living place, were collected in a structured proforma. Unstandardised regression coefficients (95%) were used for evaluating the association among variables with KAP and mental health during COVID-19. The statistical significance level was determined at p<0.05.The mean correct answer score regarding knowledge about COVID-19 was 23.5 (SD=2.1), indicating an overall 87% correct rate. The mean correct answer score regarding attitude towards COVID-19was 18.4 (SD=2.3), indicating an overall 87.2% correct rate. The mean correct answer score regarding practice towards COVID-19 was 35 (SD=3.4), indicating an overall 89.7% correct rate. The mean correct answer score regarding mental health status during COVID-19 was 24 (SD=4.7), indicating an overall 80% correct rate. Thus, the results showed that being female; belonging to a higher age group; having a healthcare related occupation; being married; and having a higher level of education were significantly associated with higher KAP test scores. Furthermore, belonging to a higher age group; having a healthcare related occupation; being married; and having a higher level of education were significantly associated with poor mental health.
