The Practice of Third Molar Extraction in Taiwan
台灣第三大臼齒拔除之執行情形
摘要
Aims: This study aimed to estimate how the third molar extraction differs by sex, age, tooth position, hospital level, payment code, and the number of teeth extracted at the same appointment in Taiwan. Methods: Two longitudinal health insurance databases for 2005 and 2010 were used. The rate of the third molar extracted with a 95% confidence interval (CI) was computed. A chi-square test and analysis of variance were made. Results: Most patients received third molar removal between 18 and 30 years old, and the highest rate was in 21-23 years old. Females tended to have more third molar extraction at a younger age (before 38 years old) than males. The upper third molars were predominantly removed by nonsurgical extraction, and the lower third molars were equally removed by nonsurgical extraction and surgical odontectomy. The medical center tended to extract two or more third molars at the same appointment. Most third molar extraction (upper and lower) was performed in dental clinics, followed by a regional hospital, medical center, and local hospital. Conclusions: This study has demonstrated the third molar extraction practice pattern reimbursed by the National Health Insurance (NHI) Program in Taiwan. The practice rate of third molar extraction was a statistically significant difference between hospital levels. In addition, within higher-level medical care institutions, the dentists or surgeons tended to extract two or more third molars at the same time.

目的：評估拔除第三大臼齒於性別、年齡、牙齒位置、醫院層級、健保給付之間的差異。方法：對全民健保資料庫作二手資料分析計算95％信賴區間及執行卡方檢定及變異數分析。結果：大部分患者於18至30歲之間拔除第三大臼齒。相較男性，女性較年輕時（38歲之前）拔除第三大臼齒。上顎第三大臼齒主要以非手術拔除，下顎則非手術和手術拔除比例相當。醫學中心有較高的比例於同時拔除兩個或更多的第三大臼齒。上下第三大臼齒拔除數量最多於診所進行，其次是區域醫院，醫學中心和地區醫院。結論：報告台灣第三大臼齒拔除於全民健康保險給付下之執行狀況。第三大臼齒拔除情形於不同醫院層級間，有統計差異。較高層級醫療機構中，較傾向於同時拔除兩顆或更多的第三臼齒。
