유치와 영구치의 외상 양상 및 치료에 대한 후향적 연구 = A Retrospective Study of the Pattern and Treatment of Traumatic Dental Injury to Primary and Permanent Teeth

국문 초록 (Abstract)

본 연구는 치아 외상의 양상과 외상 후 초진 시기의 지연이 치료에 미치는 영향에 대해 알아보고자, 2009년 1월부터 2013년 12월까지 전남대학교 치과병원 소아치과에 치아 외상을 주소로 내원한 환자 378명(외상 치아 940개)을 대상으로 기록을조사하여 다음과 같은 결과를 얻었다.
외상의 빈도는 남자가 여자보다 2배 더 높았다. 전체 외상의 원인은 넘어짐(36.5%)이 가장 많았고, 상악 중절치(66.9%)가 가장 많이 영향을 받았다. 유치에서 가장 흔한 외상 유형은 아탈구(43.9%)였고, 영구치에서는 단순 치관파절(30.9%)이었다. 전체 환자의 10%만이 외상 후 1시간 이내에 치과에 내원하였다. 유치에서 가장 흔한 초진 시 처치는 경과관찰(53.2%)이었고, 영구치는 근관치료(27.3%)였다. 영구치에서 초진 시기의 경과에 따라 근관치료 비율은 증가하였다. 이는외상 후 초진 시기가 늦어질수록 치수가 생활력을 잃을 가능성이 높아진다는 것을 알려준다.

This study investigated the pattern and treatment of traumatic dental injury (TDI), with respect to the timeelapsed prior to the initial visit to the Department of Pediatric Dentistry, Chonnam National University DentalHospital for TDI, from January 2009 to December 2013. The dental trauma records of a total of 378 patients(940 traumatic teeth) were analyzed. The prevalence rate of dental trauma was twofold higher in males versusfemales. The principal cause of injury, among all participants, was falling (36.5%). The most commonly affectedteeth were the maxillary central incisors (66.9%). Subluxation (43.9%) represented the most common traumafor primary teeth, and uncomplicated crown fracture in permanent teeth (30.9%). Only 10% of patients visitedthe dental clinic within 1 hour of sustaining trauma. The principal treatment provided for primary teeth, duringthe initial clinical visit, was follow-up (53.2%); for permanent teeth it was root canal treatment (27.3%). Theprevalence of root canal treatment for permanent teeth increased commensurate with the time elapsed sinceinjury. These data suggest that delayed checkup following trauma may increase the risk of loss of pulp vitality.
