A group of 248 randomly selected high school girls, aged 15-16 years, completed a questionnaire and were examined clinically with regard to various oral habits and signs and symptoms of temporomandibular disorders (TMD). Common habits reported in the literature, such as gum chewing, nail biting, biting foreign objects, clenching and bruxism, eating seeds and crushing ice, as well as two less reported habits, 'jaw play' and continuous arm leaning, were evaluated. The most outstanding finding was the high prevalence and intensity of gum chewing among our study group: 92% of the girls chewed daily and 48% chewed gum for more than 3 h a day (intensive gum chewing). Statistically significant associations were found between intensive gum chewing and muscle sensitivity (P<0.001) and joint noises (P<0. 05), and between crushing ice and muscle sensitivity to palpation (P<0.005). A positive association was found between 'jaw play' and joint disturbances: reported joint noises (P<0.01), catching of the joint (P<0.01) and joint tension (P<0.001). A positive association was also found between arm leaning and reported joint noises (P<0. 05), catching (P<0.05), and joint tension (P<0.005). There was no association between the presence of bruxism and muscle sensitivity to palpation or joint disturbances. The potential harmful effects of intensive gum chewing, 'jaw play', continuous arm leaning and ice crushing are presented in this study. In light of these findings, the professional community should address these habits with proper data gathering, examination and consultation.

“…Cross‐sectional and longitudinal studies have revealed that the prevalence of signs and symptoms of mandibular dysfunction occur in children as often as they do in adults. Some of these studies were based on interview on questionnaires for subjective symptoms, while others also included clinical examinations (Grosfeld & Czamecka, 1977; Williamson, 1977; Egermark‐Eriksson et al ., 1981; Nilner, 1981; Nilner & Lassing, 1981; Gazit et al ., 1984; Dibbet et al ., 1985; Grosfeld et al ., 1985; Heikinheimo et al ., 1989; Okeson, 1989; Morunishi et al ., 1991; Kristinelli & Shim, 1992). This investigation was conducted with a questionnaire in combination with a clinical examination.…”

“…These signs and symptoms may be observed singly or in combination (Morunishi et al ., 1991). TMJ dysfunction was generally presumed to be a condition affecting only adults; however, epidemiological studies on children have reported incidences of signs and symptoms as high as in adults (Grosfeld & Czarnecka, 1977; Williamson, 1977; Egermark‐Eriksson, Carlsson & Ingervall, 1981; Nilner, 1981; Nilner & Lassing, 1981; Gazit et al ., 1984; Dibbet, Van der Weele & Uildriks, 1985; Grosfeld, Jackowska & Czarnecka, 1985; Heikinheimo et al ., 1989; Okeson, 1989; Morunishi et al ., 1991; Kristinelli & Shim, 1992).…”

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

et al. 2001

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.

“…Although only slight variations by sex have been reported in random populations (Helkimo, 1979), a recent epidemiological study by Grosfeld, Jackowska & Czarnecka (1985) among adolescents and young adults reveals a significant over-representation of females in the groups with temporomandibular joint (TMJ) dysfunction.…”

Prevalence of signs and symptoms of mandibular dysfunction among adults aged 25, 35, 50 and 65 years in Ostrobothnia, Finland

1988

The prevalence of objective signs and subjectively perceived symptoms of mandibular dysfunction were studied in a sample comprising 1600 subjects, 400 each aged 25, 35, 50 and 65 years. Eighty per cent of the subjects were examined clinically. The prevalence figures were higher among the females than among the males, and a slight tendency for higher frequencies of clinical signs was observed with increasing age. In view of the severity of clinical signs preference should be given for a total of 27% of the subjects when considering the need of treatment. The number of remaining teeth in subjects with natural teeth and no additional removable dentures had no marked influence on the prevalence of mandibular dysfunction, but subjects with complete dentures had signs and symptoms of dysfunction more often than those with natural dentition. The sex and age differences can partly be explained by the higher frequency of complete dentures in females than in males and in the older age groups.
