Abstract
The aim of this study was to determine the relationship of malocclusion with the presence and severity of temporomandibular disorders (TMDs) in children. A clinical examination was performed in 87 patients (from 4 to 14 years of age) who attended the dentistry clinics of Universidad del Valle. The 77 patients studied had malocclusions; 55 patients had TMD and 67.3% were female. The most frequent symptom of TMD was articular unilateral noise with 33.8%, followed by pain in at least one masticatory muscle with 26%. TMJ pain was observed in 24.7% of the patients. There was a statistically significant relationship between the presence and severity of TMD with type of dentition and transverse malocclusion, respectively. The presence of TMD in children with malocclusion presented in a high frequency. TMD depends on the type of dentition and its severity is dependent on transverse malocclusion.
Highlights
The temporomandibular joint (TMJ) is a ginglymoarthrodial synovial joint that along with its groups of muscles can perform backward, forward, and bilateral mandibular movements.[1]

The present study found a high frequency of TMD in patients with posterior crossbite, followed by anterior crossbite and open bite, but the most severe sagittal malocclusion was Class II division 1 malocclusion
Summary
The temporomandibular joint (TMJ) is a ginglymoarthrodial synovial joint that along with its groups of muscles can perform backward, forward, and bilateral mandibular movements.[1]. Its prevalence ranges from 20 to 50% in adults and 16 to 68% in children and adolescents.[4,7]
