Dental cementum is a vital tissue which demonstrates continuous apposition throughout the life of the tooth. This study was conduct on 101 impacted and 106 erupted mandibular third molar teeth extracted from healthy patients, aged 18-30 years. The buccolingual ground sections were prepared. The distance between the edges of enamel and cementum were measured with micrometer attached with light m...

Although the mechanical management of impacted teeth is a routine task for most orthodontists, certain impactions can be frustrating, and the esthetic outcome can be unpredictable if the surgeon uncovers the impacted tooth improperly.

BACKGROUND The odontogenic cystic lesions happened in the angle and ramus region are frequently associated with impacted mandibular third molars. The treatment plan was difficult to work out for the huge cystic lesions with deeply impacted third molars, since the enucleation with simultaneously removing the deeply impacted teeth may cause serious complications. Therefore, the marsupialization o...

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...

An impacted left mandibular second molar (tooth 37) was extracted, but most of its dental follicle remained in the socket. The crown and dental papilla of an unerupted, left mandibular third molar (tooth 38) were then placed into the socket of tooth 37. Successful interaction between the dental follicle of tooth 37 and the crown and dental papilla of tooth 38 led to the formation of a new tooth...
