Prevalence of temporomandibular dysfunction in Turkish children with mixed and permanent dentition

Abstract

This study was carried out to determine the prevalence of temporomandibular joint (TMJ) dysfunction in mixed and permanent dentition and to evaluate the sex distribution in Turkish children. One hundred and eighty-two children with mixed dentition and 212 with permanent dentition were selected for the study, which used a questionnaire and clinical examination. Children with one or more signs (TMJ sounds, TMJ tenderness, muscle tenderness, restricted mouth opening) and/or symptoms (TMJ pain during mastication and mouth opening, restriction of the jaw opening and TMJ sounds) met the criterion of TMJ dysfunction. The total prevalence of signs and symptoms of TMJ dysfunction in the studied population was 68% (68% in girls and 68% in boys) in mixed dentition and 58% (61% in girls and 56% in boys) in permanent dentition. The Z-test and analysis of variance (ANOVA) were used for statistical analysis of the difference between the results. The total prevalence of signs and symptoms of TMJ dysfunction in mixed dentition was found to be higher than in permanent dentition (P < 0.05). No statistically significant difference was found in the total prevalence of TMJ dysfunction between girls and boys.

Incidence of sleep bruxism among children in Itanhandu, Brazil

“…Some earlier studies found such a correlation [40,41], while a more recent study did not [8]. Epidemiological studies have reported signs and symptoms in children to be as frequent as in adults [41,42] and that the reduced prevalence in children could be partly related to the fact that most signs and symptoms in young children are characterized as mild and therefore hard to detect [43].…”

Temporomandibular disorders and oral parafunction in children living with their parents and children living in institutional protective care: a comparative study

“…The questionnaire used in this study was adapted from similar questionnaires used to examine TMD in children and adolescents and was implemented through interviews. Before conducting the survey, the questionnaire was administered to 40 children who were not included in the study and their responses were evaluated for clarity and comprehensibility.…”

“…While TMD generally affects adults, epidemiological studies have reported signs and symptoms of TMD in #bib11 #bib12 #bib13 #bib14 #bib15 % of children and adolescents. Given these prevalence rates, additional research is needed to evaluate TMD in younger individuals, since early diagnosis may prevent the disease from progressing to a stage where it causes irreversible destruction of the intra‐capsular structures of the TMJ and affect normal craniofacial growth.…”

Temporomandibular disorders and bruxism in childhood and adolescence: Review of the literature

“…The most prevalent clinical signs of TMD are TMJ sounds (upon palpation), limitation of mandibular movements, TMJ and muscle tenderness [2,3]. Symptoms, such as headache, TMJ sounds, bruxism, difficulty in opening the mouth, jaw pain and facial pain have been reported [2].…”

“…TMD have generally been presumed to be conditions affecting only adults; however, epidemiological studies have reported signs and symptoms in children and adolescents to be as frequent as in adults [2]. The most prevalent clinical signs of TMD are TMJ sounds (upon palpation), limitation of mandibular movements, TMJ and muscle tenderness [2,3].…”
