OBJECTIVES Impacted teeth, if left untreated, have a potential to induce various complications. The aim of the current study was to determine the prevalence and pattern of impacted mandibular third molar in the Iranian population. STUDY DESIGN This cross-sectional study was performed in patients who were referred to the Department of Oral Radiology between July 2009 and October 2010 to obtain...

Impulses in 45 single mechanoreceptive afferents were recorded from the human inferior alveolar nerve with permucosally inserted tungsten microelectrodes. All afferents responded to mechanical stimulation of one or more premolar or molar teeth and most likely innervated their periodontal ligaments. For each afferent, isolated "ramp-and-hold" shaped force profiles of similar magnitudes (252 +/- ...

Introduction: Considering the importance of avoiding the outcomes of injury to the inferior alveolar nerve and its accessory branches, the present study was conducted with the purpose of determining the frequency of bifid mandibular canals using cone beam computed tomography images in an Iranian population. Materials and methods: In this cross sectional study, 221 CBCT images were evaluated ...

radicular cysts arising from deciduous teeth are rare. this report presents a case of radicular cyst associated with a primary molar following pulp therapy and discusses the relationship between pulp therapy and the rapid growth of the cyst. the treatment consisted of enucleation of the cyst sac and extraction of the involved primary teeth and 20 months follow up of the patient. early diagnosis...

The possibility of the shedding primary teeth aspirated into the bronchus is not taken into the consideration sofar as this matter could happen, particularly when it occurs without initial respiratory symptoms, or this episod may be forgotten. Tooth is a nonirritating foreign body and may produce few symptoms even after a prolonged time in the bronchus. Shedding primary teeth usually are only t...

During the formation of repetitive ectodermally derived organs such as mammary glands, lateral line and teeth, the tissue primordium iteratively initiates new structures. In the case of successional molar development, new teeth appear sequentially in the posterior region of the jaw from Sox2 cells in association with the posterior aspect of a pre-existing tooth. The sequence of molar developmen...

During the formation of repetitive ectodermally derived organs such as mammary glands, lateral line and teeth, the tissue primordium iteratively initiates new structures. In the case of successional molar development, new teeth appear sequentially in the posterior region of the jaw from Sox2(+) cells in association with the posterior aspect of a pre-existing tooth. The sequence of molar develop...
