PURPOSE This study was performed to determine the relationship between the stage of tooth eruption (both vertical and mesio-angular) and chronological age. MATERIALS AND METHODS Indirect digital panoramic radiographs were used to measure the distances from the dentinoenamel junction (DEJ) of the second molars to the occlusal plane of the second molar teeth and of the adjacent third molars in ...

BACKGROUND AND AIM: The first permanent molar is the first permanent tooth that erupted in 6-7-year-old and is very high risk for caries. Parent’s awareness has very important role in oral and dental health of children. The aim of this study was to assess the awareness of parents of 7-8-year-old children in Kerman about presence of the first permanent molar and concepts of preventive dentistry ...

The aim of this study was to investigate the differences between two groups of patients with either erupted or impacted mandibular third molars before and after orthodontic treatment. All patients were treated with Begg appliances following extraction of the four first premolars. The erupted group consisted of 14 subjects and the impacted group 13 subjects. Lateral cephalometric films, peri-api...

Excessive intake of fluoride (F) by young children results in the formation of enamel subsurface porosities and pits, called enamel fluorosis. In this study, we used a single high dose of F administered to hamster pups to determine the stage of ameloblasts most affected by F and whether pit formation was related to F-related sub-ameloblastic cyst formation. Hamster pups received a single subcut...

Cementoblastoma is a rare benign lesion that represents less than 1% of all odontogenic tumours. It’s characterized by proliferation of cementum-like tissue and in almost all cases tends to be associated with an erupted permanent tooth, most often the first molar. We present an unusual case of a large cementoblastoma that affected the right mandibular body, extending from the first premolar to ...

A sample of 41 dentulous dry mandibles from adult domestic pigs were studied in order to compare both the right and left sides according to age. Samples were grouped according to dental status: “subadults” (erupting third molar, n=19) and “adults” (fully erupted third molar, n=22). Individual levels of asymmetry were analysed from the xand y-coordinates of 16 landmarks on the dorsal aspect of t...

In the past the benign cementoblastoma was recognized in the World Health Organization’s classification of odontogenic tumors as one of the cementoma neoplasias. Recently the benign cementoblastoma is included into ‘Mesenchyme and/or odontogenic ectomesenchyme, with or without odontogenic epithelium’ odontogenic tumors. Benign cementoblastoma has characteristic radiologic and microscopic featur...
