利用Vitapex作為乳臼齒根管治療封填劑之探討
Utilizing Vitapex as a Filling Material for Primary Molars: A Retrospective Study
摘要
研究目的：本研究的目的在於探討利用Vitapex作為乳牙根管封填劑臨床上所遭遇的影響變數。 方法：以病歷回溯的方式，審視自2002年1月至2008年12月止，於兩個兒童牙科治療中心，由五位兒童牙科醫師進行看診與治療之案例。共計498名病患，其中有75名病患，94顆乳臼齒符合條件。一切臨床治療步驟遵照共同的標準作業程序治療方針。調查影響乳牙Vitapex牙髓切除術成功的因子包括性別、年齡、牙齒部位、軟組織的發炎情形、疼痛史、牙齒動搖程度、術前X光片上病理症狀、術前X光片上牙根吸收、術後Vitapex根管治療封填劑之流失、不同術者、患者行為、填充程度、以及乳臼齒種類（第一或第二乳臼齒）。 結果：在為期6至48個月的觀察時間（平均16.5個月），整體治療成功率為87.3%。在多項因素中對於成功率有顯著影響的包括有:牙齒動搖程度、術前X光片上牙根吸收、術前X光片上根尖病變、術後Vitapex根管治療封填劑之流失。對於成功率不具影響的因素包括有：性別、年齡、牙齒部位、軟組織的發炎情形、疼痛史、不同術者、患者行為、填充程度、乳臼齒種類。 結論：利用Vitapex進行乳牙根管充填可達到合理的成功率(87.3%)，並無不當反應發生，顯示出Vitapex可作為臨床上乳牙根管充填的適當材料。

Purpose: To determine the variables that influence upon the success rates of teeth treated with a Vitapex pulpectomy. Methods: Seventy-five retrospective charts (94 teeth) of pulpecomies on primary molars were reviewed at two pedodontic dental centers from Jan 2002 to Dec 2008. The influencing variables on the success rates of Vitapex pulpectomy including gender, patient age, tooth type, soft tissue condition, pain history, tooth mobility, preoperative radiolucent lesion, preoperative root resorption, wash-out, operators, patient’s behavior, root canal filling quality and molar type were assessed. Results: Ninety-four teeth had a follow-up time ranging from 6 to 48 months with a mean being 16.5 months. The success rate was 87.3%. The following factors were demonstrated to be significantly related to the success rates: preoperative root resorption, preoperative radiolucent lesion, and wash-out. The influencing factors not related to the success rates included gender, tooth type, soft tissue condition, pain history, operators, patient's behavior, and molar types. Conclusions: Vitapex pulpectomy demonstrated a high success rate of 87.3%. It can be used as a good canal filling material for primary teeth.
