Quality of Life and Temporomandibular Disorders in Patients With Skeletal Class III Malocclusion With Cleft Lip and Palate

Abstract

Objective The aim of the study was to assess the quality of life (QOL), oral health-related QOL (OHRQOL), temporomandibular disorders (TMDs), and psychological factors in patients with skeletal Class III malocclusion with cleft lip and palate (CLP) and without CLP. Design Case–control. Setting Primary care, institutional practice. Patients One hundred thirty-six patients with skeletal Class III malocclusion with CLP (n = 68) and without CLP (n = 68). Main outcome measures QOL and OHRQOL were assessed using the World Health Organization Quality of Life-BREF (WHOQOL-BREF) questionnaire and the Oral Health Impact Profile-14 questionnaire, respectively. TMDs and psychological factors were assessed using the Research Diagnostic Criteria for TMD (RDC/TMD). Results No differences in QOL were found between the groups ( P > 0.05). Patients with CLP reported a better OHRQOL ( P = 0.025) in the physical pain, physical disability, and psychological disability domains ( P < 0.05). Patients with CLP presented with less myofascial pain (OR, 0.28; 95% CI, 0.11-0.71] and other articular conditions (OR 0.24; 95% CI 0.06-0.90]. More patients with CLP reported no chronic pain ( P = 0.012). The QOL of patients with CLP with no depression or with no nonspecific physical symptoms including pain (NSPSIP) was better than that of patients without CLP. The OHRQOL of patients with CLP without TMDs or no psychological factors was better than that of patients without CLP. Conclusions Patients with skeletal Class III malocclusion who require orthognathic surgery with CLP have better OHRQOL and present with fewer TMDs than those patients without CLP.

Successful orthodontic and surgical treatment of a patient with Class III malocclusion: a clinical case report

“…In the scenario of orthognathic surgeries, malocclusion has a prevalence of 6% in the ages of 7 and 15 years in Brazil [1]. The highest number of traumatic injuries to deciduous teeth occur between one and a half and three years of age and to permanent teeth between 7 and 10 years of age, with boys being more subject to dental trauma than girls.…”

“…The highest number of traumatic injuries to deciduous teeth occur between one and a half and three years of age and to permanent teeth between 7 and 10 years of age, with boys being more subject to dental trauma than girls. Class III malocclusion affects between 5% and 15% of the entire Brazilian population [1].…”

“…In this sense, orthodontics enables aesthetic treatment and a good prognosis. It is suggested that most cases of Class III malocclusion have retrusion or maxillary hypoplasia, which may or may not be associated with mandibular prognathism [1][2][3][4][5]. Treatment of Class III malocclusion before late mixed dentition appears to induce more favorable craniofacial changes, with a significant increase in maxillary sagittal growth.…”
