Wilson曲线与颞下颌关节紊乱病的相关性研究进展

颞下颌关节紊乱病(TMD)的病因目前尚未完全阐明,病因主要来自牙合因素、社会心理因素、解剖因素、免疫因素以及关节负荷过重等多个方面。牙合因素作为颞下颌关节紊乱病中的影响因素,在颞下颌关节紊乱病的发生及发展过程中起到了推动性的作用。牙合曲线作为牙合因素中代表因素的一种,在TMD的发病机理中占有重要的地位。牙合、颞下颌关节与咀嚼肌共同构成口颌咀嚼系统的核心,三者相互联系,互相影响。     

上海市12岁青少年颞下颌关节紊乱与前牙咬合关系的流行病学研究

目的　调查上海市12岁青少年颞下颌关节紊乱的患病情况,分析其与前牙咬合的关系。方法　于2018年在上海市16个区随机抽取816名12岁青少年,通过触诊和听诊进行颞下颌关节检查及前牙咬合关系检查,建立 Logistic回归模型分析颞下颌关节紊乱与前牙咬合之间的关系。结果　最终808名12岁青少年完成检查,其中120名存在颞下颌关节紊乱症状,患病率为14.9%,症状以开口型偏斜为主（占90.8%）。Logistic回归分析显示,下牙列中线偏斜、前牙深覆牙合与颞下颌关节紊乱的发生相关,其中主要是与开口型偏斜相关。结论　上海市12岁青少年颞下颌关节紊乱主要表现为开口型异常,深覆牙合伴下牙列中线偏斜会增加开口型异常的风险,临床中应对该类人群进行密切观察并采取适当措施防止症状加重。

An orthodontic study of temporomandibular joint disorders. Part 1: Epidemiological research in Japanese 6-18 year olds.

Malocclusion is considered one of the etiological factors of temporomandibular joint disorder (TMD). The purpose of this study was to investigate the prevalence of TMD and the relationship between TMD and the type of occlusion. The sample consisted of 7337 Japanese children, 6-18 years old, 3219 boys and 4118 girls. TMD symptoms were recorded as well as the type of occlusion in children with TMD. The prevalence of TMD overall was 12.2%. The prevalence increased with age and was slightly higher in girls (13%) than in boys 11.1%. This difference was not statistically significant. Joint sound as the only symptom was more common in younger subjects. TMD symptoms seemed more complicated with age when pain and abnormal jaw movement combined with sound. Joint sound was the most common symptom (89.3%), followed by the combination of sound and pain (2.2%). The incidence of other symptoms was under 1%. In subjects with TMD, 24.9% exhibited crowding, 20.1% had excessive overjet, 6.8% deep bite, 6.3% edge-to-edge bite, 5.6% anterior crossbite, 5.4% open bite, and 3.8% posterior crossbite. Morphologically normal occlusion was observed in 27.1%. In this study, many subjects with TMD had malocclusions. Early treatment may be important in the prevention of severe TMD. Although those with morphologically normal occlusions were included, a more detailed study concerning other causes of TMD is needed also.     

A prospective investigation over two decades on signs and symptoms of temporomandibular disorders and associated variables. A final summary

The aim of this summary of a longitudinal investigation on temporomandibular disorders (TMD) was to present the prevalence figures of signs and symptoms of TMD and certain other examined variables, and the correlations between these variables, over a 20-year period. Originally, 402 randomly selected 7-, 11-, and 15-year-olds were examined clinically and by means of a questionnaire. The same examination procedure was repeated three times: after 4-5 years and after 10 and 20 years, respectively. Signs and symptoms of TMD were mainly mild, but common already in childhood. They increased up to young adulthood, after which they leveled out. Progression to severe pain and dysfunction was rare, and spontaneous recovery from more pronounced symptoms was also rare. Significant correlations between reported bruxism and TMD symptoms were found, and a baseline report of tooth-grinding was a predictor of TMD treatment during the 20 years covered by the investigation. Occlusal factors were only weakly associated with TMD signs and symptoms. However, a lateral forced bite between the retruded contact position (RCP) and the intercuspal contact position (ICP) and a unilateral crossbite deserve further consideration as possible local risk factors for development of TMD. In conclusion, a substantial fluctuation of TMD signs and symptoms was observed in this sample of Swedish subjects followed for 20 years from childhood to adult. The demand for TMD treatment was low at all examinations, while the estimated treatment need was larger. One-third of subjects who had some kind of orthodontic treatment did not run a higher risk of developing TMD later in life.     

Multivariate analysis of risk factors in relation to TMD symptoms

The epidemiological studies on risk factors for temporomandibular disorders (TMD) are still extremely lacking. Therefore, their aetiological significance has scarcely been documented. The aim of this study was to quantitatively investigate the relationship between hypothesized risk factors and the precipitation and perpetuation of TMD symptoms. The same 672 adults who participated in a previous study ( Matsuka et al., 1996 ) were selected for this study. All subjects had already answered a self‐administered questionnaire and the same questionnaire was sent to them 4 years after the first survey. The questionnaire failed to reach 58 subjects at the second survey. Of the remaining 614 subjects, 367 (166 males and 201 females with a mean age of 53·1 ± 14·2 years) returned the questionnaire, for a return rate of 59·8%. Information about three TMD symptoms [temporomandibular joint (TMJ) pain, limitation of mouth opening, TMJ noise] was obtained from the questionnaire, and fluctuation of these symptoms was assessed by comparing three pairs of answers between the first and second surveys. Information about 18 hypothesized risk factors for TMD (age, sex, trauma, bruxism, malocclusion, oral habit, etc.) were also obtained from the questionnaire at the first survey. To evaluate how strongly each risk factor was associated with precipitation and perpetuation of TMD symptoms, odds ratio of each risk factors for precipitating or perpetuating TMD symptoms was calculated by means of logistic regression analysis. Statistically significant risk factors for precipitating TMD symptoms were lip biting for TMJ pain (3·65) and trauma for limitation of mouth opening (3·20), and statistically significant risk factors for perpetuating TMD symptoms were female for TMJ pain (4·50) and TMJ noise (3·85) (odds ratio in parenthesis). The possible aetiological significance of these factors in TMD should be validated by future research.     

History factors associated with symptoms of temporomandibular disorders

Differences in prevalence of head or neck trauma, orthodontic treatment and molar oral surgery procedures reported by individuals were compared among patients with temporomandibular disorders (TMD) and with two comparison groups (a sample of asymptomatic individuals, and a sample with mild or early signs). Association to specific TMD symptoms was tested amongst the comparison groups. Trauma was the most significant factor characterizing TMD patients. History of trauma was also more common among those otherwise normal but symptomatic individuals in the non-patient comparison group. Specific TMD symptoms were significantly associated with history of trauma in the comparison group. Significantly more women TMD patients had a history of orthodontic and molar oral surgery treatment than the asymptomatic comparison group. History of orthodontics was also associated with the symptomatic sample of the comparison group in women, but it was not significantly related to any specific TMD symptoms. Symptomatic members of the comparison group could not be differentiated based upon history of molar oral surgery. Certain risk factors may have been delineated, but causal relationship of treatment requires study of co-existing and predisposing behavioural and structural factors.

Occurrence of clinical signs of temporomandibular disorders in adult Finns

AIMS: To study the age- and gender-related prevalence of signs of temporomandibular disorders (TMD) in the Finnish adult population. METHODS: A clinical health examination was performed as a part of a Health 2000 Health Examination Survey in 2000 and 2001. A nationally representative sample included 8,028 Finns at least 30 years of age, of whom 79% participated also in an oral health investigation, including examination of the stomatognathic system in order to assess the presence of certain TMD signs: maximum interincisal distance < 40 mm, pain in temporomandibular joints or masticatory muscles, and sounds in temporomandibular joints (crepitation, clicking). RESULTS: Thirty-eight percent of the subjects had at least 1 sign of TMD. All the signs studied were more common in women than men. Overall, signs of TMD were also associated with age; the older the subject, the higher the prevalence of the TMD signs. However, when stratified by gender, the association with age was not as clear, and gender differences were observed in the prevalence of the single TMD signs at different ages. CONCLUSION: Signs of TMD may be more common among the elderly than is usually reported.     

Temporomandibular disorders, otologic symptoms and depression levels in tinnitus patients

The aim of this study was to determine the prevalence of signs and symptoms of temporomandibular disorders (TMD) and otologic symptoms in patients with and without tinnitus. The influence of the level of depression was also addressed. The tinnitus group was comprised of 100 patients with tinnitus, and control group was comprised of 100 individuals without tinnitus. All subjects were evaluated using the research diagnostic criteria for temporomandibular disorders (RDC/TMD) to determine the presence of TMD and depression level. Chi-square, Spearman Correlation and Mann-Whitney tests were used in statistical analysis, with a 5% significance level. TMD signs and symptoms were detected in 85% of patients with tinnitus and in 55% of controls (P≤0·001). The severity of pain and higher depression levels were positively associated with tinnitus (P≤0·001). It was concluded that tinnitus is associated with TMD and with otalgia, dizziness/vertigo, stuffy sensations, hypoacusis sensation and hyperacusis, as well as with higher depression levels.
