ABSTRACT
A panoramic radiograph is more likely utilized in children with high caries risk and mixed dentition, and it can be complemented by other X-rays (such as periapical and/or bitewings). This study analyzed 1359 panoramic radiographs taken over 33 years at the Pedodontics Clinic of the State University of Rio de Janeiro in order to determine the prevalence of dental anomalies in mixed dentition children. The population evaluated had 670 (49.3%) boys and 689 (50.7%) girls, ranging in age from 5-12 years, with a median age of 8 years. The total prevalence of anomalies detected was 11.72%; anodontia and supernumerary teeth were the most reported (4.63% and 3.31%, respectively). Statistical differences noted were in the presence of supernumary teeth in males (4.9%, P <.001) and the presence of anodontia in females (6.1%, P = .009). Based on these findings, a panoramic radiograph can help to analyze transitional dentition, as well as complement the clinical examination at the first dental visit of a pediatric patient with a high risk for caries.

The aim of this study was to evaluate clinically a bonded space maintainer, which would reduce chair-side time and cost. Sixty appliances were fabricated from 0.7mm stainless steel round wire and bonded using light-cured composite to the two teeth adjacent to the site of extraction of a posterior primary tooth. Twenty males and sixteen females (age range 5-9-years-old) were selected from the Pedodontic clinic of the State University of Rio de Janeiro. The sixty space maintainers were divided into two groups according to the site in which they were placed: a) absent first primary molar and b) absent second primary molar. Impressions and study models were obtained prior to and 6 months after bonding the appliances. During this period only 8.3 per cent of failures were observed, most of them from occlusal or facial trauma. Student t-test did not show statistically significant alterations in the sizes of the maintained spaces during the trial period
