In this technique, maxillary and mandibular anterior teeth were simultaneously prepared and restored first. This was followed by simultaneous preparation of maxillary and mandibular posterior teeth that were restored in canine guided occlusion. The technique and sequence followed here is unique and is not available in dental literature. This technique reduces number of appointments while fulfilling all objectives. Periodontal followup over 3 years was satisfactory. A restorative treatment protocol has been devised for fluorosis which will act as a guide for the dental practitioners.展开更多

The purpose of this study was to examine the prevalence of dental anomalies and investigate their possible association with gender and dental occlusion. Methods: Panoramic radiographs and study models of 500, 12-year-old school children (273 girls, 227 boys) were analyzed for the presence of dental anomalies including agenesis, taurodontism, pulp stones, microdontia, macrodontia, impaction, short roots, supernumerary teeth, ectopic eruption and transposition. The subjects were divided into three groups according to the Angle classification (Class Ι, n = 252. Class ΙΙ, n = 227. Class ΙΙΙ, n = 21). Percentages and chi-square test were used for evaluation of the data. Results: In this population 28.2% of the subjects showed at least one dental anomaly. Statistically significant associations were observed between agenesis and Angle Class II dental occlusion (P = 0.03), and between agenesis and gender (P = 0.004). Conclusions: Agenesis was a predominant dental anomaly in girls and was found twice as often in subjects with Class ΙΙ, than with Class Ι dental occlusion.展开更多
