“…The presence of occlusal interferences in the mouth has been noted to have an incidence of between 75-89% in Agerberg and Sandstrom's study. 5 This study's subject group consisted of teenagers and young adults. Unilateral tooth contacts in retruded position were found in 75% of both subject groups.…”

“…Comparing this with the whole mouth study of Agerberg and Sandstrom, 5 the incidence in this limited area of study would appear to be high. The high incidence of occlusal interferences involving unopposed teeth is of great clinical significance to the restorative dentist, not only when restoring the unopposed tooth, or replacing the missing opponent.…”

Objectives To determine the incidence and extent of overeruption in unopposed posterior teeth; to determine the incidence of occlusal interferences associated with unopposed posterior teeth; and to detect an association between the extent of overeruption and the presence of occlusal interference. Design The study was a single centre clinical retrospective analysis. Setting The setting was in the Combined Care Clinic of Leeds Dental Institute. The patients were undergoing routine restorative care by final year undergraduate dental students during 2000. Subjects and methods All patients over18 years of age with one or more unopposed posterior tooth, were invited to participate. A sample group of 120 subjects were recruited. A clinical occlusal examination was carried out and the presence of initial retruded contact position (RCP) contacts and excursive interferences were recorded. Study models were made and digitally scanned. Outcome measures Measurements of overeruption from the curve of Spee were made from the images obtained, by a single observer. Reliability of the measurements was assessed by means of a Bland Altman Plot. The presence and site of RCP contacts and excursive interferences were recorded by a single observer. Reliability of the measurements was assessed by means of Kappa scores. The association between overeruption and the presence of occlusal interference was examined using Spearmans Correlation Coefficient. Results A total of 120 subjects were recruited, with a total of 155 unopposed sites. Eighty-one of the sites belonged to male subjects, 74 to female subjects. The mean age of the group was 50.9 years, Standard deviation 13.9. Eighty-three per cent of sites displayed overeruption (95% CI 78-90), ranging from under 0.5 mm to 5.4 mm. The reliability of the observations was found to be good. A total of 51.6% (95% CI 44-60) of unopposed teeth were involved in RCP contacts or excursive interferences. Thirty-two sites were involved in more than one contact or interference. The intra-examiner agreement was found to be good, using Kappa. The findings of the Spearman's correlation, show that if an association exists between overeruption and occlusal interference, it is weak, and of no statistical significance. Conclusions Eighty-three per cent of unopposed teeth are likely to overerupt, and the extent of the overeruption may be marked. The incidence and extent of overeruption is of clinical significance, not only in terms of treatment planning to prevent undesirable vertical movement, but also in the restoration of the edentulous space. The reliability of observations made in the study was found to be good, justifying the methodology. Fifty-one point six per cent of unopposed teeth are likely to be involved in RCP contacts or excursive interferences. The incidence is of clinical significance when planning the restoration of unopposed teeth, or the associated edentulous space. Only a weak statistical association was demonstrated between the degree of overeruption and the presence of occlusal interferen...

ABSTRACT:The aim of this study was to evaluate the prevalence and severity of temporomandibular disorders (TMD) in Brazilian college students. A questionnaire was administered to 2,396 students. Seventy-three percent of women (mean age 21.94 ± 5 years) and 27% of men (mean age 22.41 ± 4.8 years) answered the questionnaire. The anamnestic index was used to classify the volunteers according to TMD severity degree. The results showed a higher percentage of men without TMD (43.74%) (p < 0.05, Chi-square test). The women exhibited some degree of severity (73.03%) at a higher frequency than men (56.26%). No significant differences were observed between sexes for a same TMD severity degree (p > 0.05). The results indicated TMD prevalence in Brazilian college students similar to that presented in other studies found in the literature reviewed. Longitudinal studies are recommended to follow the prevalence and health care needs in this population. DESCRIPTORS: Temporomandibular joint disorders; Epidemiology; Questionnaires; Prevalence. RESUMO:O objetivo deste estudo foi avaliar a prevalência e a severidade da disfunção temporomandibular (DTM) em universitários brasileiros. Participaram do estudo 2.396 estudantes. Responderam ao questionário 73% de mulheres (21,94 ± 5 anos) e 27% de homens (22,41 ± 4,8 anos). O índice anamnésico foi utilizado para classificar os voluntários por nível de severidade da DTM. Os resultados mostraram uma maior porcentagem de homens sem DTM (43,74%) (p < 0,05 teste Qui-quadrado). As mulheres mostraram algum nível de severidade (73,03%) com maior freqüência que os homens (56,26%). Não foram evidenciadas diferenças de freqüência entre os sexos classificados com DTM de mesma severidade. Os resultados indicam que a prevalência de DTM em universitários brasileiros é semelhante à de outros trabalhos presentes na literatura. Estudos longitudinais são necessários para acompanhar a prevalência e a necessidade de tratamento nessa população. DESCRITORES: Transtornos da articulação temporomandibular; Epidemiologia; Questionários; Prevalência. INTRODUCTIONThe expression Temporomandibular disorders (TMD) is a generic designation for a subgroup of orofacial pain disorders. This classification comprises the pain complaints in the temporomandibular joint (TMJ) region, muscle fatigue, especially of the masticatory muscles, impaired jaw movement, and articular sounds. The multifactorial TMD etiology is related to emotional tension, occlusal interferences, teeth loss, postural deviation, masticatory muscular dysfunction, internal and external changes in TMJ structure, and the various associations of these factors 6,17 .TMD prevalence studies have demonstrated a large amount of people with signs and symptoms in clinical and subclinical degrees. Thus, we have found a high TMD prevalence in non-patients, i.e., among those who do not seek for health care attention 22 . A non-patient prevalence study indicates closely 75% of subjects with just one TMD sign, and 33% with at least one symptom 7 . Another estimate related ...

“…Although TMD prevalence difference between the genders is yet to be thoroughly understood, some theories have tried to explain why women seem to be more affected than men, as Agerberg and Sandstrom 30 , believe that women are not so skilled to deal with pressure, causing a greater number of functional disorders. Abubaker et al 31 shows that estrogen receptors in women's TMJ are present in greater quantity.…”

The interaction between Temporomandibular disorders (TMD) and otalgia is, even nowadays, a reason for speculation and hypotheses raising. Several researchers suggest causes, consequences and alleged treatments. Study design: This is an epidemiological, sectional cohort study of prevalence. Aim: The study demonstrates the prevalence of patients harboring TMDs in an otorhinolaryngology department. Material and methodos: During a two-month period, 221 patients from the Otorhinolaryngology Department of the Hospital da Cidade de Passo Fundo, State of Rio Grande do Sul, Brazil were analyzed. A previously validated questionnaire was applied for data collection. Results: In the present study, the need for dental assessment was observed in 48 patients ( 21.72%). In this group there were 35 female (72.9%) and 13 males (27.1%). Only 15 patients (7.24%) were entirely free of TMD symptoms. The remaining patients reported the following TMD symptoms: headaches: 34.39%, neck and shoulder pain: 28.50%, pain on the ear region: 30.32% and joint noises in 23.98%. Conclusion: The prevalence of Temporomandibular disorders was 21.72%, being significantly higher among female subjects (p:0.0001). The prevalence regarding the indexes, was: TMD absent: 37.56%; mild TMD: 40.72%; moderate TMD 19% and severe TMD: 2.72%.
