ABSTRACT
Aim: The current purpose of the survey is to completely evaluate parents' attitudes, knowledge, and perceptions of myofunctional appliances. Materials and Methods: Parents in Chennai participated in this cross-sectional web-based questionnaire survey. Pilot study was carried out to determine the sample size, and 500 individuals were the final sample size. The 10 organized, predesigned, and validated questions are on awareness of myofunctional appliance. Results: The result of the survey showed that in 500 subjects, 79.8% were aware of skeletal problems. The proportion of parents willing to recommend the use of such treatments is about 70%, while 69% believe that myofunctional appliances are important in correcting skeletal problems. Conclusion: The present study has established that most parents know about the functional appliance and have an understanding of how to distinguish between skeletal problems. In order to diagnose skeletal issues in an appropriate age range for the individual, more awareness about appliances is necessary and needs to be developed.
ABSTRACT
Although there is easy accessibility of infection control measures and recommendation regarding the PPE, most of the dentists failed to practice appropriate infection control measures. The aim of the current survey was conducted to assess the knowledge, perception, and attitude regarding the role of PPE among the dental care professionals in COVID-19. This is cross-sectional web-based questionnaire survey conducted among dental care professionals in Tamil Nadu. The self-administered questions related to the PPE infection control measures were collected from 500 subjects. The statistical analysis was done using Statistical Package for Social Sciences SPSS (V 22.0). The frequency distribution was computed. This survey revealed that all the 500 (100%) respondents had awareness about the role of PPE in COVID-19 pandemic. Among the 500 study subjects, 93.2% had well-known knowledge about PPE, 60.4% of dentist strictly adheres to the use of PPE in routine dental practice, 80.2% of dentist mentioned PPE is safe and effective against spread of infection, and 93.4% of dentist had awareness about donning and doffing. Conclusion: From the beginning of this COVID-19, information provided by the health organization like CDC and WHO regarding the role of PPE had positive impact among the dental care professionals.
ABSTRACT
Background Remineralizing agents demonstrate potential to reverse early carious lesions. Theobromine containing dentifrices claim to remineralize enamel lesions effectively. The aim of this in-vitro study was to evaluate and compare the remineralization potential of dentifrices containing theobromine, 0.21% sodium fluoride (NaF) with functionalized tricalcium phosphate (f-TCP) and amine fluoride on artificial enamel caries. Materials and methods Sound extracted human premolars were demineralized to produce deep artificial carious lesions. The teeth were sectioned longitudinally and allocated to three treatment groups with nine specimens in each group: Group A (NaF + f-TCP), Group B (amine fluoride), and Group C (theobromine). The specimens were then subjected to pH cycling for seven days. Confocal laser scanning microscopy (CLSM) was utilized to record the patterns of demineralization and remineralization. One-way ANOVA and paired t-test were used to analyze changes in lesion depth. The level of significance was set at p<0.05. Results All three dentifrices effectively remineralized artificial carious lesions (paired t-test, p<0.001). Of the groups, Group A (54.97%) reported the highest percentage change in lesion depth values followed closely by Group B (51.51%) and Group C (31.71%), respectively. Conclusion Within this in-vitro study, theobromine containing dentifrice was effective in remineralizing lesions of enamel. However, theobromine demonstrated less remineralization potential in comparison to dentifrices containing NaF + f-(TCP) and amine fluoride.
