Mandibular third molar and inferior alveolar canal

Area of Science:

• Oral and Maxillofacial Surgery
• Neurology
• Dental Radiology

Background:

• Third molar extraction is a common dental procedure.
• Inferior Alveolar Nerve (IAN) injury is a potential complication.
• Assessing and predicting IAN damage is crucial for patient safety.

Purpose of the Study:

• Determine the incidence of Inferior Alveolar Nerve (IAN) damage post-lower third molar surgery.
• Identify etiological factors contributing to IAN injury.
• Develop a predictive model for IAN injury risk.

Main Methods:

• Prospective study of 50 patients undergoing mandibular third molar extraction.
• Clinical and radiological evaluation including nerve proximity assessment.
• Standardized data collection on patient demographics and surgical factors.

Main Results:

• 6% incidence of temporary labial sensory impairment observed.
• Most sensory disturbances resolved within six weeks post-surgery.
• No permanent nerve damage reported in this cohort.

Conclusions:

• Patient age, root development, impaction degree, and radiographic nerve canal position are significant predictors of sensory deficit.
• These factors can be utilized to construct a predictive model for IAN injury.
• Risk stratification can aid in surgical planning and patient counseling.
