ABSTRACT
OBJECTIVE: The purpose of this study was to analyze the occurrence of symptoms in patients with unerupted mandibular third molars and to investigate the associated pathoses. STUDY DESIGN: Through a review of clinical records and periapical radiographs of completely unerupted and partially erupted mandibular third molars, a retrospective study was carried out. For each axial inclination, symptoms and pathoses associated with these teeth were analyzed. Statistical differences were tested by chi square analysis. RESULTS: Most of the patients were between 16 and 30 years of age. In 83% of cases, the mandibular third molars were partially erupted; in the other 17% of cases, the mandibular third molars were completely unerupted. Pain was the most frequent symptom in both groups. Pericoronitis was found mostly in third molar teeth with vertical and distal inclinations (P< .05), whereas caries was found mainly in mesially tipped third molars (P < .05). CONCLUSIONS: Most of the patients were in the third decade of life. Partially erupted mandibular third molars had more symptoms than completely unerupted teeth. Pain and pericoronitis were the most common problems in patients with unerupted third molars.

The incidence of clinically significant oroantral communications (OACs) after simple tooth extraction during the period 1980-9, at the Faculty of Dentistry, Mahidol University, Bangkok, Thailand, was studied retrospectively. The total number of OACs was 87. The tooth most frequently involved was the upper first molar, followed by the second and third molars. The difference, however, was not statistically significant (P > 0.05). The sockets of the palatal roots of the first and the second molars were most frequently involved. There was no statistically significant difference between the incidence of OACs on the right and the left sides (P > 0.05).

Currently, the inferior alveolar nerve block is sometimes ineffective for a number of reasons. The extra-intraoral landmark technique (EIL technique) was modified and compared in effectiveness with the direct technique in patients undergoing inferior alveolar nerve block. The results showed that the success rates of the EIL technique based on both subjective and objective responses were significantly greater than those of the direct technique. The EIL technique also resulted in significantly less pain from the injection than the direct technique.

Thirty-six patients underwent endodontic surgery involving 66 teeth, with each root canal being retrofilled with either gold leaf or amalgam. A follow-up of most patients was conducted for 6 to 24 months. There was no significant difference in bone healing between the gold leaf-filled and amalgam-filled root cavities (p greater than 0.05). Gold leaf appeared to be a good alternative retrograde filling material and had a number of benefits over amalgam.

Gold leaf, made of fine and pure gold, is considered to be an alternative retrograde filling material. Apical surgery was performed in three cases with the use of gold leaves as filling material. The radiographs showed the excellent bone healing in the apical region. The operative procedure was easy with the use of gold leaf as filling material.
