dentigerous cysts, commonly encountered in the practice of dentistry, are benign odontogenic cysts associated with crowns of unerupted and/or impacted permanent teeth. they frequently occur during the second and third decades of life. treatment modalities range from enucleation to marsupialization, which may be influenced by the age of the patient, severity of impaction, and root form of associ...

The purpose of this study was to find out the types of pathologies that can arise in association with impacted wisdom teeth. Two hundred consecutive patients scheduled for extraction of one or more of their impacted wisdom teeth were evaluated clinically and radiographically. Orthopantogram (OPG) was the standard radiograph. 194 (97 %) of the teeth were associated with pathologies. Pericoroniti...

This study was conducted on 48 impacted and 51 erupted maxillary permanent canine teeth extracted from healthy patients aged 13-73 years. Longitudinal buccolingual ground sections were prepared. The distance between the edges of cementum and enamel in each specimen was measured with an eyepiece micrometer. A correlation test was applied between age and the distance between enamel and cementum m...

A supernumerary tooth is that which is present additionally to the normal series and can be found in any region of the dental arch. An impacted tooth is defined as the one which is embedded in the alveolus, so that its eruption is prevented, or the tooth is locked in position by bone or the adjacent teeth. The occurrence of multiple supernumerary teeth in only one patient in the absence of an a...

BACKGROUND AND AIM: Supernumerary tooth (ST) is considered as a developmental tooth abnormality in number that most often occurs in the anterior region of the maxilla. They may erupt or remain impacted in the alveolar bone. The impacted teeth can cause eruptional disturbances for the adjacent developing teeth. CASE REPORT: A case of bilateral supplemental maxillary lateral incisors in a nonsynd...

PURPOSE The purpose of the present study was to retrospectively evaluate the clinical findings and treatment results for impacted permanent teeth associated with odontomas. MATERIALS AND METHODS We retrospectively investigated 73 odontomas in 72 patients who visited Kyungpook National University Dental Hospital from April 2004 through November 2011. The study was performed using medical recor...

One of the most performed procedures in the specialty of oral and maxillofacial surgery is removal of impacted teeth, especially third molars. Impaction is defined as failure of teeth to erupt into the dental arch within the expected time [1,2]. The reasons for tooth impaction include several factors subdivided into a local and general factors such as position and size of adjacent teeth, dense ...

The object of the study was to assess the incidence of lingual nerve sensory loss during removal of impacted mandibular third molar teeth, and the effect of retention of the lingual plate on the incidence. The subjects were 395 patients, of whom 362 completed the study. Removal of 504 impacted wisdom teeth with retention of the lingual plate was performed. Results showed that 381 (76%) of the t...

Objective The aim of this retrospective study was to evaluate the long-term effects of orthodontic traction on root length and alveolar bone level in impacted canines and adjacent teeth. Material and Methods Sample consisted of 16 patients (nine males and seven females), mean initial age 11 years and 8 months presenting with unilaterally maxillary impacted canines, palatally displaced, treate...
