Introduction And Aim:
Delayed-onset infection was defined as an infectious swelling and trismus accompained by pain or the presence of suppuration starting after the discharge of the patient, generally a week after surgery. Our aim was to describe incidence and possible risk factors of delayed-onset infection after lower wisdoom tooth removal.
Material And Methods:
Retrospective study of 851 lower third molar surgeries, performed between January 2013 and August 2017 at Semmelweis University Faculty of Dentistry, Department of Oro-Maxillofacial Surgery and Stomatology, has been done. The teeth were removed by 2 surgeons. Under age of 26, a case-control study comprising a total of 150 lower third molar surgeries were done to indentify possible risk factors.
Results:
10 delayed-onset wound infections were recorded after suture removal (1.17% of the patients). The mean time elapsing from surgery to delayed-onset infection was 30 days. Lower third molars with total soft tissue coverage, a bigger amount of bone coverage, a lack of distal space (Pell-Gregory class III), deeper impaction (Pell-Gregory classes B, C) or mesioangular tilt are associated with the development of this complication (p<0.05). Female sex and young age seem to be risk factors, too.
Conclusion:
Patients with risk factors should be warned that infection may still occur several weeks after surgery. The clinicians should observe these patients longer and emphasize keeping their wound clean for a prolonged period. Orv Hetil. 2018; 159(31): 1278-1283.
