Surgical experience and patient morbidity after third molar removal.

OBJECTIVES

The present study aimed to assess differences in patients' postoperative morbidity after third molar removal in relation to the surgeon's level of experience and other intraoperative factors.

MATERIAL AND

METHODS

Patients admitted for prophylactic removal of asymptomatic third molars were prospectively followed up on day 3 and 10 after surgery in the context of the M3BE-study. Uni- and multivariable logistic regression was performed to assess the associations between surgeon's (in)experience and postoperative discomfort. Other contributing factors were gender, age, extraction method (osteotomy or not), and number of extractions and involved jaws.

RESULTS

In total, 7 senior surgeons and 28 surgical residents operated 2560 patients (8672 third molars). Differences in postoperative morbidity on day 3 and 10 after surgery were small. The results showed no significant associations between surgeon's inexperience and postoperative discomfort (pain, trismus, swelling), except for persistent pain (day 10; OR 1.468; p = 0.0016). No effect was observed on the occurrence of postoperative nerve complications. It was shown that postoperative morbidity was more dependent on factors like age, gender, number of extractions and intraoperative osteotomy.

CONCLUSION

We may conclude that patient recovery following third molar removal is affected by other factors than surgical experience. However, surgical residents seemed to cause significantly more persisting pain problems 10 days after surgery.
