Ectopic eruption of teeth into regions other than the oral cavity is rare although there have been reports of teeth in the nasal septum, mandibular condyle, coronoid process, palate, chin, and maxillary sinus. Occasionally, a tooth may erupt in the maxillary sinus and present with local sinonasal symptoms attributed to chronic sinusitis. We present a case of an ectopic maxillary third molar too...

Benign cementoblastoma is a rare lesion representing less than 1% of all odontogenic tumours. It usually affects young people and is located in the posterior jaw. In almost all cases the tumour tends to be associated with an erupted permanent tooth, most often the first molar: only rarely has an association with an impacted or deciduous tooth been reported. The authors present a case of a cemen...

Tooth renewal is initiated from epithelium associated with existing teeth. The development of new teeth requires dental epithelial cells that have competence for tooth formation, but specific marker genes for these cells have not been identified. Here, we analyzed expression patterns of the transcription factor Sox2 in two different modes of successional tooth formation: tooth replacement and s...

OBJECTIVE To determine the tooth brushing, tongue cleaning and snacking behaviour of dental technology and therapist students. METHODS A descriptive cross-sectional study of students of Federal School of Dental Therapy and Technology Enugu, Nigeria. Self-administered questionnaire was used to obtain information on demography, frequency, duration and technique of tooth brushing and tongue clea...

precise localization of the third molars in relation to the inferior alveolar nerve canal is critical from a clinical point of view and strongly affects the surgical treatment outcome. recently, by using three-dimensional modeling software, the relationship of third molar root apices and inferior alveolar nerve canal can be better understood. in this study, the spatial relationship of two surgi...

OBJECTIVE The objective of this study was to evaluate the load-fatigue performance of posterior ceramic onlay restorations relative to two variables: preparation design (with or without buccal veneers); and the existing amount of tooth structure (non-worn tooth, worn tooth). METHODS Sixty extracted third molars were divided into five groups. One group received a mesial-occlusal-distal (MOD) g...

Introdouction: Impacted and partially erupted third molars can cause various symptoms and pathologies. The aim of this study was to determine the association between commonly observed pathological conditions and the impaction depth of lower third molar teeth. Materials and methods: In this retrospective study, 370 panoramic radiographs including 724 lower third molars were evaluated to asses...

Introduction Based on previous researches, dental pulp stem cells (DPSCs) are easily accessible with limited morbidity after collection. Their embryonic origin, from neural crests, explains their multipotency. DPSCs are primarily derived from the pulp tissues of the teeth.Objective: This study was undertaken to isolate, culture, and characterize two different third molar and first premolar hum...
