Dentigerous cyst is the most prevalent type of odontogenic cyst and is associated with crown of an unerupted or a developing tooth and accounts more than 24% of jaw cysts. Here, we present an interesting case of dentigerous cyst in a 4-year-old boy, which developed around an unerupted maxillary first premolar. Histological examination revealed a cyst with(More)
The Gorlin-Goltz syndrome, also known as nevoid basal cell carcinoma syndrome (NBCCS), is an infrequent multisystemic disease inherited in a dominant autosomal way, which shows a high level of penetrance and variable expressiveness. It is characterized by odontogenic keratocysts in the jaw, multiple basal cell nevi carcinomas and skeletal abnormalities.(More)
BACKGROUND AND OBJECTIVES The most caries-susceptible period of a permanent first molar tooth is the eruption phase, during which the enamel is not fully matured and it is usually difficult for the child to clean the erupting tooth surfaces. Sealing occlusal pits and fissures with resin-based pit and fissure sealants is a proven method to prevent occlusal(More)
Composite restorations are popular because of their superior esthetics and acceptable clinical performance. But shrinkage is still a drawback. Polymerization shrinkage results in volumetric contraction, leading to deformation of the cusps, microleakage, decrease of marginal adaptation, enamel micro-cracks and postoperative sensitivity. A new class of ring(More)
Late congenital syphilis is a very rare clinical entity, and its early diagnosis and treatment is essential. Dental findings often provide valuable evidence for the diagnosis of late congenital syphilis. It occurs due to the transmission of the disease from an infected mother to her fetus through placenta. This long forgotten disease continues to effect(More)
AIM The aim of this study was to evaluate the carious dentin removal efficacy of new rotary polyamide burs capable of selectively removing infected dentin without removing sound dentin. METHODS AND MATERIALS This study included 40 subjects with bilateral occlusal carious lesions on mandibular first permanent molars. The lesions were randomly assigned to(More)
