Aims: Condylar region of the mandible is the most vulnerable site to fracture due to its anatomical weakness. It has been noted that mandibular third molars may reduce the occurrence of condylar fractures. This study was conducted to verify this hypothesis. Materials and methods: This retrospective study of records of 147 mandibular fracture patients treated during 5 year period during 2008 to ...

The role of third molars in causing late mandibular incisor crowd ing is controversial. Various studies have been conducted to eva luate their relationshi p. The purpose of this article is to (a) rev iew the studies regarding the mandibular third molars and late mandibular arch crowd ing (b) fi nd out the cause and effect re lat ionship between them (c) eva luate the just ificat ion of prophyla...

BACKGROUND Scientific literature estimates that around 18 to 40 % of asymptomatic third molars are extracted. The aims of the present study were to determine the indications for extraction of asymptomatic lower third molars in a sample of Spanish and Portuguese dentists, and to relate these indications to the clinicians' training and professional experience. MATERIAL AND METHODS A survey cons...

This study was conducted on 72 American Society of Anesthesiologists class 1 patients scheduled for extraction of a mandibular third molar after inferior alveolar nerve block. Each patient was randomly administered one of the following ropivacaine concentrations: 0.75%, 0.5%, 0.375%, or 0.25% (18 patients per group). Onset of block (mean +/- SD) was rapid for both 0.75% (1.4 +/- 0.4 minutes) an...

Displacement of root fragments into adjacent anatomical areas is an uncommon complication of the removal of teeth. This paper describes the management of a mandibular third molar root fragment that was forced into the antero-inferior aspect of the pterygomandibular space. The importance of tomographical radiographs in the visualization of the displaced root is also discussed.

The removal of wisdom teeth is often associated with severe postoperative edema and pain, and operation on the third molar can cause local inflammation that impairs lymph transport. The objective of the study was to assess the efficacy of manual lymph drainage (MLD) in reducing swelling following bilateral wisdom tooth removal. Ten consecutive patients with bilateral impacted wisdom teeth that ...

OBJECTIVE This study investigated the effect of the fluorescent dye rhodamine B (RB) for interfacial micromorphology analysis of dental composite restorations on water sorption/solubility (WS/WSL) and microtensile bond strength to dentin (µTBS) of a 3-step total etch and a 2-step self-etch adhesive system. MATERIAL AND METHODS The adhesives Adper Scotchbond Multi-Purpose (MP) and Clearfil SE ...

The purpose of this study was to determine the personal utility of asymptomatic third molar removal in military patients. From 1 to 30 days (mean = 7.4) after the extraction of one or more third molars, 100 returning patients (all male, mean age = 20.1) were asked to respond to hypothetical questions concerning the extraction of asymptomatic third molars. If the likelihood of third molars ever ...

OBJECTIVE To determine the optimum surgical treatment for oral antral communications (OAC) and to understand the main post-operative complications. STUDY DESIGN Meta-analytical, observational and retrospective study of 1.072 cases of OAC obtained from a literature review of 15 articles. RESULTS OAC occur slightly more often in men and during the fourth decade of life. Its primary etiologica...

BACKGROUND Fractures of the mandibular angle are common and comprise 31% of all mandibular fractures. Multiple recent studies report a 2-3 fold increased risk for mandibular angle fractures when un-erupted mandibular third molars are present. The objective of this study was to assess the frequency of un-erupted mandibular third molar in mandibular angle fractures. METHODS This cross-sectional...
