The presence of asymptomatic third molars can represent a potential problem in the mandible when these teeth are retained and the patient has lost all normally erupted teeth. Once the mandibular first and second molars are removed, the mandibular body becomes weaker with time, increasing the complexity, morbidity and incidence of complication in the surgical procedure to remove the retained thi...

The authors undertook a prospective study to evaluate the influence that the anatomical dimensions of the ramus of the mandible and the presence of lower third molar teeth may have on the sagittal split ramus osteotomy. The anatomical dimensions measured included the width of the anterior mandibular ramus, the height of the corpus posterior to the second mandibular molar and the antero-posterio...

Four patients attending for the extraction of an impacted lower third molar are reported. The aim of this paper is was to describe a technical approach, which facilitates impacted lower third molar extraction, minimizing the ostectomy, thus reducing secondary postoperative manifestations and avoiding possible periodontal defects on the distal side of the second mandibular molar. To facilitate t...

On a chemically defined growth medium the degree of substitution of thymidine with 5-bromodeoxyuridine (BUdR) in DNA of Tetrahymena pyriformis was controlled by the concentration of tetrahydrofiolic acid, BUdR and thymidine in the medium. A correlation between the degree of BUdR substitution in DNA and the reduction in rate of total RNA synthesis has been established. It was found that the redu...

BACKGROUND AND OBJECTIVES Surgical removal of a mandibular impacted third molar is one among the most common oral surgical procedures. The objective of this study was to assess and identify risk indicators influencing extended operation time in relation to the surgical removal of mesioangular impacted mandibular third molar, position A, Class I and to evaluate the incidence of postoperative swe...

Damage to the inferior alveolar nerve (IAN) during third molar extraction is a major concern for patients and clinicians. A wide range of the incidence of temporary and permanent neurologic disturbances of the IAN as a consequence of mandibular impacted third molar extraction has been reported in the literature. The incidence of IAN injury reported in the literature ranges from 1.3% to 5.3%. Th...

An unusual odontogenic cyst, which was originally believed to be a clinical dentigerous cyst associated with an impacted mandibular third molar, was found histologically to demonstrate the characteristics of a glandular odontogenic cyst with para- and orthokeratinization. These histologic diversities were interpreted as a reflection of the pluripotentiality of the epithelial remnants of the man...

BACKGROUND Successful extraction of third molars depends on preoperative diagnosis and planning. Gold standard preoperative examinations are performed through computed tomography, decreasing risks and avoiding potential accidents. The present report highlights the value of preoperative examinations in face of accidentally displaced third molars. METHODS An 18-years-old female patient underwen...

Third molar extraction is a common procedure frequently accompanied by moderate or severe pain, and involves sufficient numbers of patients to make studies relatively easy to perform. The aim of the present study was to determine the efficacy and safety of the therapeutic combination of 10 mg piroxicam, 1 mg dexamethasone, 35 mg orphenadrine citrate, and 2.5 mg cyanocobalamin (Rheumazin) when c...
