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

This paper discusses a method for assessing adult age based on the relationship between age and measurement of the pulp/tooth area ratio (RA) of the second molar teeth. The sample consisted of 312 Italian white Caucasian patients (135 men, 177 women) aged between 14 and 24 years. Orthopantomograph samples (OPGs) were analyzed by the same observer and calibrated by kappa statistics. Probabilitie...

Extraction of an impacted third molar is one of the most frequently performed techniques in oral and maxillofacial surgery. Surgeons can suffer numerous external injuries while extracting a tooth, with percutaneous injuries to the hand being the most commonly reported. In this article, we present a case involving a percutaneous injury of the surgeon's femoral region caused by breakage of the fi...

Clodronate, a non-N-containing bisphosphonate, strongly inhibits bone resorption and also has anti-inflammatory properties. The purpose of this study was to examine the effect of the local administration of clodronate on orthodontic tooth movement. Both the right and left upper first molars of 26 7-week-old male Wistar rats were moved buccally with a standardized expansion spring. Clodronate so...

The removal of impacted mandibular third molar is a common surgical procedure entailing some risk of complications, especially when the tooth and the inferior alveolar nerve and/or lingual cortical plate are in close proximity. A technique that can reduce the possibility of damage is the Ultra Sonic Bone Surgery. The aim of this report is to present a paradigmatic case of an impacted mandibular...

Ectopic third molar teeth are those that are impacted in unusual positions or that have been displaced and are at a distance from their normal anatomic location [1]. It is common have to ectopic eruption of a tooth within the oral cavity but rare in other sites of the jaw [2]. Reports are present with teeth eruption in the nasal septum, ascending ramus of mandible, mandibular condyle, and lower...

BACKGROUND/OBJECTIVE Panoramic and periapical radiographs are normally used in impacted third molar teeth surgeries. The aim of the present study was to evaluate and compare the distortion of the erupted third molar teeth on panoramic and periapical radiographs. PATIENTS AND METHODS A total of 44 radiographs were obtained of 22 patients (age range, 18-24 years) referred to the faculty of dent...
