OBJECTIVE The aims of this study were to investigate the frequency and characteristics of dental transpositions and to evaluate associated dental anomalies in a large sample of Turkish Anatolian population. STUDY DESIGN A retrospective study was performed using panoramic radiographs of 6983 patients (4092 females and 2891 males) ranging in age from 12 to 27 subjected to Faculty of Dentistry a...

JADA 142(6) http://jada.ada.org June 2011 651 A45-year-old woman visited her general dentist because of severe pain in the right mandibular posterior region. Her first molar contained a large mesialocclusal-distal amalgam restoration, and the patient experienced symptoms consistent with irreversible pulpitis. In addition, radiographs showed changes associated with the mesial root. The second mo...

The maxillary tuberosity can fracture during extraction of a molar tooth. If a small bony fragment is affected, the extraction of the tooth and tuberosity continues; however, a conservative approach is advised if the bony fragment is large. In a modified blind surgical technique, the tooth is removed without the fractured bone.

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...

In order to clarify the peripheral mechanisms of ectopic persistent pain in a tooth pulp following pulpal inflammation of an adjacent tooth, masseter muscle activity, phosphorylated extracellular signal-regulated protein kinase (pERK) and TRPV1 immunohistochemistries and satellite cell activation using glial fibrillary acidic protein (GFAP) immunohistochemistry in the trigeminal ganglion (TG) w...

Background The mechanisms underlying tooth pulp hypersensitivity associated with masseter muscle hyperalgesia remain largely underinvestigated. In the present study, we aimed to determine whether masseter muscle contraction induced by daily electrical stimulation influences the mechanical head-withdrawal threshold and genioglossus electromyography activity caused by the application of capsaicin...

The aim of this study was to describe the replantation of a maxillary second right molar, which had been removed for surgical reasons in order to remove a dentigerous cyst associated with the adjacent third molar, and the case's 12-month follow-up. A 51-year-old man presented swelling in the right maxillary area. Radiographic examination showed a large radiolucency in close proximity to the thi...

The primary objective of this in vitro study was to compare the absolute marginal discrepancy (AMD) of CAD/CAM produced Procera AllCeram crown copings, fabricated on die stone master models of two different tooth groups, incisor and molar. Two maxillary central incisors and two first molars typodont teeth were prepared with 0.8 mm of circumferential chamfer, duplicated 9 times to obtain 36 die ...
