Does the Tooth Sectioning Method Impact Surgical Removal of the Distoangular Impacted Mandibular Third Molar?

Area of Science:

• Oral and Maxillofacial Surgery
• Dental Research
• Surgical Techniques

Background:

• Distoangular impacted mandibular third molars present surgical challenges due to their anatomical position.
• Effective tooth sectioning is crucial for minimizing bone removal during extraction.
• Comparing different sectioning methods can optimize surgical outcomes.

Purpose of the Study:

• To compare the clinical outcomes of two distinct tooth sectioning methods for distoangular impacted mandibular third molars.
• To evaluate operative time, postoperative pain, trismus, and facial edema associated with each technique.

Main Methods:

• A single-blinded randomized controlled trial involving patients with distoangular-impacted mandibular third molars.
• Group A: Conventional sectioning at the cementoenamel junction. Group B: Modified sectioning of only the distal portion of the crown.
• Primary outcome: operative time. Secondary outcomes: pain, trismus, and edema assessed on postoperative days 3 and 7.

Main Results:

• Operative time was significantly shorter in the modified sectioning group (22.72 ± 10.79 min) compared to the conventional group (31.61 ± 14.13 min) (P < .05).
• No significant differences were found in postoperative pain (P = .95), facial edema (P = .88), or trismus (P = .54 on day 3, P = .36 on day 7).
• The need for rescue analgesia was significantly lower in the modified sectioning group (P < .01).

Conclusions:

• Both tooth sectioning methods are acceptable, but the modified technique offers a faster operative time.
• The modified sectioning method resulted in a reduced need for rescue analgesia, suggesting its superiority.
• This modified approach may be a preferred technique for extracting distoangular-impacted mandibular third molars.
