[Anatomical and radiological studies on additional mandible teeth anesthesia considering innervation variability]

Area of Science:

• Anatomy
• Oral Surgery
• Anesthesiology

Background:

• The mandible contains numerous foramina that transmit vital neurovascular structures.
• Knowledge of specific foramina is essential for effective regional anesthesia in dentistry.
• Variations in mandibular foramina can impact anesthetic efficacy and surgical procedures.

Purpose of the Study:

• To investigate the location and characteristics of nutritional foramina in the mandible.
• To correlate these foramina with anesthetic techniques for mandibular procedures.
• To enhance the understanding of mandibular anatomy for improved surgical outcomes.

Main Methods:

• Anatomical dissection and observation of mandibular specimens.
• Radiographic analysis to identify intraosseous canals.
• Correlation of anatomical findings with clinical anesthetic practices.

Main Results:

• Nutritional foramina containing significant blood vessels and nerves were identified in the frontal mandibular lingual region.
• Intraosseous canals connecting to the inferior alveolar nerve canal were observed in the retromolar area, especially with third molars.
• These findings suggest implications for anesthesia techniques.

Conclusions:

• Specific mandibular foramina are important landmarks for regional anesthesia.
• Understanding retromolar anatomy enhances anesthesia for third molar extraction.
• Anatomical knowledge improves the safety and efficacy of dental anesthesia.
