초록

본 연구에서는 치아교모도에 의한 연령감정법을 이용하여 측두하악장애환자의 치아연령을 일반 정상인과 비교하고, 측두 하악장애환자의 구강습관이 치아교모에 미치는 영향을 조사하고자 하였다. 단국대학교 치과병원 구강내과에 측두하악장애를 주소로 내원한 환자 65명을 실험군으로 하고, 측두하악장애증상이 없는 정상인 22명을 대조군으로 하였다. 문진 및 설문조사를 통해 대상자의 구강습관을 조사하였으며, 임상 및 방사선검사후 치아교모도를 조사하여 치아연령을 산출하였다. 실험군과 대조군의 치아교모도의 차이 및 각각의 구강습관이 치아교모에 미치는 정도를 분석하기 위해 t-test 및 one-way ANOVA, multiple comparison t-test를 이용하였다. 연구 결과 대조군에 비해 실험군의 치아교모도가 유의성 있게 증가했으며, 조사된 구강습관중 이갈이, 이악물기, 식사습관(단단하고 질긴 음식)순으로 치아교모도에 영향을 주었다. 따라서, 측두하악장애환자의 연령감정시 증가된 치아교모도에 의해 나타날 수 있는 실제 연령과의 차이를 고려해야 한다. 특히, 20-30대의 연령감정시에 측두하악장애환자의 경우 약 3.5세, 이중 특히 이갈이의 습관이 있는 경우에는 약 5.3세의 감정연령의 증가가 있을 수 있음을 감안해야 한다. 또한, 측두하악장애환자는 일반 정상인보다 치아 교모가 심한 경향이 있고 이는 치아와 턱관절에 더 많은 하중이 가해지고 있음을 의미하므로 측두하악장애환자의 치료시에는 반드시 이러한 요인을 제거하는 치료술식을 병행해야 할 것으로 사료된다.

This study was performed to investigate the dental ages of the patients with temporomandibular disorders(TMD), using a method of age estimation by dental attrition, and to compare the differences of dental ages between control and experimental groups. In addition, they were compared according to oral habit. Clinical evaluations for the tooth attrition were to examine the study models of 65 TMD patients (mean age of 26.6 years, aged 18 to 40) had visited to the Department of Oral Medicine and Orofacial Pain Clinic, Dental Hospital, Dankook University as a experimental group and 22 volunteers (mean age of 25.4 years, aged 23 to 36) without TMD as a control group. Age differences were calculated subtracting real age from estimated age. Age differences between experimental and control groups were compared statistically between groups classified according to oral habit. As a results, dental age was increased significantly in TMD patients compared with normal subjects. Oral parafunctions which increased dental age were bruxism, clenching and heavy chewing in order. Conclusively, it should be consider that there can be much discrepancy between real age and age estimated by dental attrition in patients with TMD. In addition, it is suggested that dentists should try to protect the tooth from attrition by various parafunction on treating the patients with TMD.
