INTRODUCTION Migration of dislocated lower third molar into the condylar region is quite rare. Attention should be taken to avoid condyle fracture. METHODS 49-year-old patient had an ectopic lower left third molal in the condylar region, suffered from a submandibular and masseter space abscess. Removal of the molar via intraoral approach was chosen avoiding facial nerve branches and unnecessa...

Removal of an impacted superior third molar is usually a simple and uncomplicated procedure for an Oral and Maxillofacial Surgeon. Nevertheless, complications are possible and include infection, facial swallowing, trismus, wound dehiscence, root fracture or even orosinusal fistula. Iatrogenic displacement into the infratemporal fossa is frequently mentioned but rarely reported. This anatomical ...

OBJECTIVE The aim of this study was to identify the relative risk of damage to the inferior dental (ID) and lingual nerves in patients undergoing lower third molar removal. STUDY DESIGN A single surgeon reviewed 1,000 patients. RESULTS Temporary ID neurosensory deficit was highest (11%) when root apices were intimate to the ID nerve and lowest (0.9%) when close or distant from the nerve. Pe...

Previous studies have suggested methods for predicting third molar tooth eruption radiographically. Still, this prediction is associated with uncertainty. The aim of the present study was to elucidate the association between cephalometric measurements on profile and panoramic radiographs and to find a simple and reliable method for predicting the eruption of the mandibular third molar by measur...

Objective: Impacted tooth develops when the fails to erupt into its anatomical functional position. Theaim of this prospective study was find out common clinical effects impacted lower molar on adjacent tissuesand evaluate relationship between signs and symptoms as regards gender agerespectively. Material Methods: Data for were obtained using a well-structured questionnaireat Teem Dental Hospit...

Precise localization of the third molars in relation to the inferior alveolar nerve canal is critical from a clinical point of view and strongly affects the surgical treatment outcome. Recently, by using three-dimensional modeling software, the relationship of third molar root apices and inferior alveolar nerve canal can be better understood. In this study, the spatial relationship of two surgi...

Subcutaneous emphysema is a condition that results from introduction of air into soft tissues. In head and neck, it is commonly observed following fractures of paranasal sinuses. Less frequently, it may occur during surgical procedures for tooth removal, when air from dental hand-pieces is forced into surgical site. Depending on its extension, it may involve vital spaces such as mediastinum. Th...

Ectopic teeth have been rarely described in non-dental and non-oral localizations. Ectopic tooth eruption in maxillary sinus usually runs across incidentally during routine radiological or clinical evaluation because it is generally asymptomatic. If it occurs symptomaticaly; the findings like purulent rhinorrhoea, facial pain, headache, swelling, epistaxis and epiphora can be seen. It is often ...

OBJECTIVES Impacted teeth, if left untreated, have a potential to induce various complications. The aim of the current study was to determine the prevalence and pattern of impacted mandibular third molar in the Iranian population. STUDY DESIGN This cross-sectional study was performed in patients who were referred to the Department of Oral Radiology between July 2009 and October 2010 to obtain...

Ectopic eruption of teeth into regions other than the oral cavity is rare although there have been reports of teeth in the nasal septum, mandibular condyle, coronoid process, palate, chin, and maxillary sinus. Occasionally, a tooth may erupt in the maxillary sinus and present with local sinonasal symptoms attributed to chronic sinusitis. We present a case of an ectopic maxillary third molar too...
