根管充填後疼痛因素之探討

Factors Associated with Post-obturation Pain

本研究的目的是要探討根管充填後疼痛的發生與其他因素如根尖病灶(apical lesion)之大小、年齡、性別、牙齒部位、及根管充填的緻密程度等的相關性。收集自西元2000年10月至2001年4月間（約半年），根管充填後約三至四星期至台大牙髓病科之回診病患共計260位329顆牙齒，紀錄上述因素並用Chi-square方法加以統計、分析。本研究發現疼痛與年齡、性別、牙齒部位、及根管充填的緻密程度等較無相關性，不具有統計上的意義(P>0.05)。而根管充填後疼痛與牙齒有根尖病灶有顯著的相關性，且具有統計上的意義(P<0.05)。同時也發現當瘻管存在時，或在下顎前牙區域、疼痛極少發生。年齡小於20歲，根管充填後發生疼痛的情形最少，而在41歲至50歲的年齡層佔最多，隨著回診時間越長疼痛的情形則逐漸減少。

The aim of this study was to investigate whether certain factors, namely patient age and sex, size of apical lesion, tooth arch, tooth position, tooth number and quality of root canal filling, could be associated with post-obturation pain. A follow-up study of patients who had undergone obturation procedures was done over a half-year period from October 2000 to March 2001. In this study, each patient was returned to NTUH endodontic department for follow-up study after root canal filling. This study included a total of 260 patients involving 329 teeth. These factors, including size of apical lesion, age, sex, tooth arch tooth position, tooth number, quality of root canal filling and post-obturation pain were statistically analyzed by Chi-square (P<0.05). It was found that the size of the apical lesion and post-obturation pain were significantly correlated. It was also found that post-obturation pain was rare when procedures were done on mandibular anterior teeth and when fistula was present. Patients below the age of twenty were reported to have less pain than those between the ages of forty and fifty. Finally, but not surprisingly, the longer the follow-up period, the fewer the clinical symptoms that may be found in the patients.
