Abstract

Introduction Factors that contribute to swelling and trismus are complex, and they are originated by surgical trauma. The aim of the present study was to determine whether clinical and radiographic factors could predict the level of swelling and trismus after lower third molar surgery, through longitudinal approach. Methodology A prospective longitudinal trial was carried out. Forty-five patients of both genders with clinical and radiographic diagnosis of asymptomatic mandibular impacted third molar and with no intake of analgesic or anti-inflammatory drugs 12 h prior to surgery were recruited and evaluated in a 72 h follow-up period. A mixed repeated measures model and backward and restricted maximal likelihood methods were used to analyze the data. Results Male gender, body mass index (BMI), the relation to the lingual and buccal walls, and age were determinants for predicting postoperative swelling and for exerting a significant influence (P < 0.05). Conclusions This study suggests the association of male gender, the relation to lingual and buccal walls, BMI, and age with measurement of swelling.

Highlights

Factors that contribute to swelling and trismus are complex, and they are originated by surgical trauma. e aim of the present study was to determine whether clinical and radiographic factors could predict the level of swelling and trismus after lower third molar surgery, through longitudinal approach
For the swelling and trismus variables, the multivariate Mixed Repeated Measures Model (MRMM), restricted maximal likelihood (REML), and backward-stepwise methods were used. e initial model included all of the variables in the fixed component described in Table 1, and, in the random component, all times were included and each patient was measured 3 times, for a total of 135 measurements
For the trismus variable in the MRMM, the same previous methods were used, and the variance structure utilized was “varPower” [16]; the fixed component included all variables presented in Table 1, and the random component included all trismus measures. e model was compared with the null model, and this comparison showed p value > 0.05. us, the variables included in

Summary

Introduction

Factors that contribute to swelling and trismus are complex, and they are originated by surgical trauma. e aim of the present study was to determine whether clinical and radiographic factors could predict the level of swelling and trismus after lower third molar surgery, through longitudinal approach. E effect of mandibular third molar surgery on the postoperative period in the majority of patients is marked by pain, swelling, and trismus, either alone or in combination [2]. Control of these conditions comprises an important factor for clinicians, because lower third molar surgery is one of the most common procedures carried out by oral and maxillofacial surgeons [3,4,5,6,7]. In transversal or punctual measurements, it is not possible to observe changes over time
