RESUMO
Background:Background and objective: One of the unfavourable outcomes of endodontic treatment is furcal perforation. Materials such as MTA-Angelus, Biodentine and Zirconomer have been recommended for the repair of furcal perforations.In this study we compared the sealing ability of MTA-Angelus, Biodentine and Zirconia-reinforced GIC in furcal perforations using dye penetration method. Material And Methods:Access cavities were prepared in extracted mandibular molars (n= 40) using round bur in a high speed hand pieceunder water coolant. Perforations were made in the centre of furcation region using 2mm round bur.The teeth were randomly divided into 4 groups based on the material used to seal the perforation: Group I(n= 12) = MTA –Angelus , Group II (n=12)= Biodentine, Group III(n=12) = Zirconomer , Group IV (n= 4) = left unsealed (negative control group).Leakage at the repaired site was then evaluated using methylene blue dye penetration technique under stereomicroscope and data was statistically analyzed.Result:Minimum dye penetration was observed in biodentine followed by MTA, Zirconomer and control group. The results was not statistically significant (p= .08). Conclusion:According to this study, biodentine showed best of the three materials used for furcation repair.
RESUMO
Background:The World Health Organization (WHO) had declared the Novel Coronavirus as a Pandemic in March, 2020. As dentists are at an increased risk due to the aerosol transmission, it is extremely important for them to understand the virus spread.Objectives: To assess the knowledge and attitude of the dentists ofnorth Gujarat population towards the novel Coronavirus and their knowledge regarding the spread of their infections. Material And Methods:A descriptive, cross-sectional study was conducted among 274 dentists including post graduate and undergraduate dental students, faculty members and private practitioners of North Gujarat. A Questionnaire was circulated using the Google forms, consisting of two parts: first –consisted of demographic details and the second part consisted of 25 questions regarding knowledge of dentists towards the COVID-19 and its impact on their dental practice. The level of significance was set at ?0.05. Result:The study participants were well aware about the COVID-19 prevention protocols. Majority of the participants 59.5% agreed thatelective dental procedures needed to be postponed for at least 3 weeks. Also 73% stated that 90GSM of PPE kit was considered appropriate to protect from cross-infection. The results were statistically significant. Conclusion:The study concluded that dentists had sufficient knowledge regarding COVID-19 protocols but same was not implemented in their practices. Dentists should have proper knowledge regarding the transmission and prevention of infection from the virus as they are at high of developing an infection.
