RESUMO
Context: In the mixed dentition period, malocclusion is in dormant stage, any interception should be preceded by a mixed dentition space analysis. Aims: To derive new regression equation in sample subjects (indigenous group) with no intermaxillary tooth size discrepancy (Bolton's ratio) residing in Davangere and to evaluate its accuracy. To assess the difference of tooth dimensions between males and females and difference between right and left of dental arches. Setting and Design: Descriptive study. Subjects and Methods: One hundred and fifty children (11–15 years) were included and dental casts were made. A digital Vernier caliper was used for the measurement of teeth. Bolton's ratio was calculated. Group A: Casts without Bolton's discrepancy and Group B: Casts with Bolton's discrepancy. Statistical Analysis Used: The data were analyzed with the SPSS software version 22.0. New regression equations were derived using correlation and regression analysis. Results: No statistically significant difference was recorded between the actual and predicted mesiodistal widths (MDWs) of permanent canine and premolars in maxilla and mandible, with/without Bolton's discrepancy. Males had statistically significant higher mean in maxillary and mandibular canine dimensions than female and no statistically significant difference between right and left side of dental arches was found. Conclusion: New regression equation was formulated for Davangere population, in which actual and predicted widths of permanent canines and premolars were found to be almost similar when established from sample with/without Bolton's discrepancy. In MDWs, the canine showed significant sexual dimorphism and no clinically significant variations were seen in the right and left sides of both the arches.
RESUMO
Background: Early assessment of the oral health status of children has the potential to reduce or even eliminate oral diseases. Paediatricians are considered a perfect and reliable source for oral health control and prevention. In dentistry, clinical practice is directed towards attitudes that promote oral health and the paediatricians occupy a privileged position in this process. The purpose of this study was to evaluate the knowledge, attitude and awareness of paediatricians in the prevention of dental caries in 3 district quarters, India. Methods: A cross-sectional survey was undertaken among 123 registered paediatricians in Indian Academy of Paediatrics (IAP) Karnataka directory and digest 2011-2013, Karnataka society. Out of which, 42 did not participate as their email address were not available. 29 sets of questions were mailed to all 81 paediatricians. Results: The response rate of the survey was 90% (70 out of 81), a total of 59% felt that the frequency of Early Childhood Caries (ECC) in their O.P.D was at least once a week. 51% responded that bacteria causing dental caries cannot be transmitted between mother and child. 53% felt that 1 year would be ideal for first dental visit. 64% of pediatricians were not aware that fluoride dentifrices and dental sealants will prevent dental caries. Conclusions: In general, pediatricians’ knowledge, attitudes and awareness regarding oral health and prevention of dental caries was not satisfactory. It is essential to develop oral health information programs to pediatricians.
