A buccal pit is a prominent point-like depression that appears at the cervical end of mandibular molar developmental grooves. defective can be defined as in which continuity dentinoenamel junction broken and extends to dentinal level. This study aimed determine frequency pits un-erupted first second molars using cone-beam computed tomography (CBCT). The analysis was performed on CBCT images tak...

Background and Aim: The aim of this study is to determine antioxidants defense mechanism in dental follicles (DFs) of partially erupted third molars with pericoronitis evaluating levels of superoxide dismutase (SOD). Materials and Methods: Fifty-eight dental follicles of partially erupted third molars with pericoronitis as a test group and 58 healthy gingival tissues of the same patients were o...

Delayed eruption or impaction of permanent teeth is one of the severe problems that can occur during the mixed dentition period. These conditions can occur in any permanent tooth, but the incidence of delayed eruption of the permanent first molars, especially maxillary permanent first molars, is very low. Johnsen found only one case of delayed emergence of a maxillary first molar as a result of...

Odontomas are the commonest hamartomas as well as odontogenic tumor. They are a malformation in which dental tissues are represented in more or less disorderly pattern. They prevent the eruption of the teeth and mostly asymptomatic in nature. Usually they are discovered on routine radiographic examination. The odontomas which erupt in oral cavity are called as erupted odontomas and are rare in ...

1. The aim of this paper was to investigate the arthropod colonisation of a recently erupted volcano in the framework of a general model of colonisation kinetics. 2. We analysed the diversity of arthropod communities at three locations on Faial Island (Azores) using a well-defined disturbance gradient: (i) a site that is new land added by the eruption of Capelinhos Volcano of 1957; (ii) a site ...

OBJECTIVES If teeth are missing, super-eruption of teeth in the opposing arch can occur in the area and can change the occlusal plane. When missing teeth are replaced with implants, the oral surgeon must determine whether or not the super-erupted teeth need to be treated in order to normalize the occlusal plane. In this study, we evaluated the clinical prognosis of dentition after implant place...

the tumors in which odontogenic differentiation is fully expressed are the odontomas. odontomas are considered as hamartomas rather than a true neoplasm. these tumors are composed of enamel, dentine, cementum and pulp tissue. it is most commonly associated with the eruption of the teeth. they are usually discovered on routine radiographic examination. in exceptional cases, the odontoma erupts i...
