Abstract:The management of third molars involves a range of clinical challenges, particularly in deciding whether to extract asymptomatic third molars or to adopt a wait-and-see approach. This research used the UPPAAL to model and evaluate different third molar management protocols, focusing on optimizing clinical outcomes, healthcare costs, and patient well-being. Our formal modelling approach compares a preventive protocol (based on KIMO guidelines) versus a symptomatic protocol. Results demonstrated that the preventive protocol leads to a slightly higher average number of extractions per patient (3.95 vs. 3.88; a 1.8% increase). However, it significantly reduces symptomatic extractions by 65% (from 3.02 to 1.07), indicating effective early intervention. The average incidence of complications per patient was marginally higher under the preventive protocol (1.64 vs. 1.63), but complication rates per extraction were comparable between the protocols. Notably, severe complications such as alveolitis trended lower under the preventive approach (33.9% vs. 44.4%). The preventive protocol also reduced average healthcare costs per patient by 24.6% ($424.044 vs. $562.748), primarily due to the additional extractions that occur in the same operation, and lower complication expenses due to extraction happening at a young age.
