Knowledge of the size, morphology, and variation of the root canals of a primary tooth is useful in visualizing the pulp cavity during treatment. The roots of the primary teeth are formed completely approximately 16 to 20 months following eruption.1 In approximately three years the roots begin to resorb at the apex or on a lateral surface near the apex.2 The form and shape of the root canals ro...

PURPOSE The aim of the study was to report the long-term clinical performance of esthetic primary molar crowns and compare them to that of stainless steel crowns (SSC). METHODS Twenty crowns (10 conventional and 10 esthetic) placed in 10 children who had participated in a previously reported study, were assessed again after 4 years. The crowns were evaluated clinically and radiographically ac...

A case is presented of a nine-year-old male having a supernumerary maxillary right first primary molar together with a supernumerary maxillary right first premolar. The implications of early diagnosis and orthodontic management are discussed. The occurrence of supernumerary teeth in both the primary and permanent dentitions in the same patient seems to be rare. A review of the literature (inclu...

A thorough knowledge of root canal anatomy and its variation is necessary for successful completion of root canal procedures. Morphological variations such as additional root canals in human deciduous dentition are rare. A mandibular second primary molar with more than four canals is an interesting example of anatomic variations, especially when three of these canals are located in the distal r...
