To evaluate the frequency of common causes of permanent tooth extraction and severity of dental condition at the time of tooth extraction.
The cross-sectional study was conducted at the Department of Oral and Maxillofacial Surgery, Punjab Dental Hospital, Lahore, Pakistan, from February to June 2010, and involved 1026 patients who were referred for the extraction of permanent teeth. The inclusion criteria comprised caries, periodontitis, restoration failure, trauma, and local pathologies, while 3rd Molar impactions, supernumerary tooth extraction and extractions done as part of orthodontic or prosthodontic treatment were excluded. Oral hygiene was recorded using the Simplified Oral Hygiene Index. SPSS version 17 was used for statistical analysis.
The mean age of the study population was 46.60 +/- 11.321 years, and there were 611 (59.6%) males. A total of 1178 teeth were extracted. Advanced dental caries was the leading cause of tooth extraction (n = 743; 63.1%), followed by periodontitis (n = 309; 26.2%) restoration failure (n = 54; 4.6%), trauma (n = 38; 3.2%) and miscellaneous local pathologies (n = 34; 2.9%). More than half of the patients (n = 540; 52.6%) had poor oral hygiene.
Advanced dental caries is the most common cause behind tooth extraction.
评估恒牙拔除常见原因的发生频率以及拔牙时牙齿状况的严重程度。
2010年2月至6月，在巴基斯坦拉合尔旁遮普牙科医院口腔颌面外科进行了一项横断面研究，纳入了1026例因恒牙拔除前来就诊的患者。纳入标准包括龋齿、牙周炎、修复失败、创伤和局部病变，排除第三磨牙阻生、多生牙拔除以及作为正畸或修复治疗一部分而进行的拔牙。使用简化口腔卫生指数记录口腔卫生情况。采用SPSS 17版进行统计分析。
研究人群的平均年龄为46.60±11.321岁，男性611例（59.6%）。共拔除1178颗牙齿。重度龋齿是拔牙的主要原因（n = 743；63.1%），其次是牙周炎（n = 309；26.2%）、修复失败（n = 54；4.6%）、创伤（n = 38；3.2%）和其他局部病变（n = 34；2.9%）。超过半数患者（n = 540；52.6%）口腔卫生较差。
重度龋齿是拔牙最常见的原因。
