Purpose: To investigate and compare the clinical application of flap or flapless buccal surgery on the extractions of mesially/horizontally impacted 3rd molar with high or medium position impact in terms of the average surgery duration, number of root fracture, postoperative pain degree and duration, postoperative swelling degree and duration, degree of limitation of mouth opening.
Materials and methods: The present study was conducted of 28 patients who were examined and underwent bilateral extraction of impacted mandibular 3rd molar. One molar was randomly extracted with flap buccal surgery (Control Group, CG) and the other one with flapless buccal surgery (Experimental Group, EG) in the same patient.
Results: Gender distribution, average age, average surgery duration and number of root fracture between the two groups were not statistically significant (P>0.05). The postoperative pain degree, swelling degree and degree of limitation of mouth opening were all significantly greater in CG than EG. Moreover, the duration of postoperative pain and swelling were all were all significantly longer in CG than EG (0.01<P<0.05).
Conclusion: Compared with the flap buccal surgery on the extractions of mesially/horizontally impacted 3rd molar with high or medium position impact, the clinical use of the flapless buccal surgery is a safe and effective method with less swelling, pain and degree of limitation of mouth opening. However, we need further study based on the broader indications, a much larger number of patients included and a follow-up in the longer term to confirm our point.
