The purpose of this report was to describe the clinical, radiological, and histopathological features of a case of regional odontodysplasia (RA) in a seven-year-old boy who was followed for approximately two years. The case is unusual in that the dysplasia occurred in the mandible, and there was a normal-appearing tooth within the lesion, suggesting that there may be local factors that determine susceptibility of individual teeth in RA. The diagnosis of RA was based on the typical features of "ghost" teeth and evidence of disrupted calcification characterized by psammomatous bodies, hypomineralizotion of enamel, and the presence of interglobular dentin. Seguential orthopantomograms provide evidence of delayed dental development. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study was to assess and compare the clinical and radiographic success rates of low-level laser therapy (LLLT) and formocresol (FC) for pulpotomy in primary teeth. Methods: Utilizing a split-mouth technique, 106 primary molars of 36 five- to eight-year-olds were included. The teeth were selected according to specific clinical and radiographic inclusion criteria and randomly assigned to the LLLT group and FC group. A pulpotomy was performed on each molar; 53 teeth were treated with LLLT, and 53 teeth were treated using FC. Children were followed at six and 12 months for clinical and radiographic evaluation. Results: At six months, the clinical success rate was 98 percent for each group. Radiographic success was 100 percent for the LLLT group and 98 percent for the FC group. At 12 months, both groups showed a clinical success of 96.1 percent Radiographic success at 12 months was 100 percent and 98 percent for LLLT and FC, respectively Conclusions: Both low-level loser therapy and formocresol pulpotomy techniques showed favorable clinical and radiographic outcomes in human primary molar teeth over 12 months. Further longitudinal studies with longer follow-up periods and larger sample sizes are encouraged. [ABSTRACT FROM AUTHOR]
