Tooth extractions are one of the most common procedures in oral surgery. The objective of this study was to identify the reasons for tooth extraction in adult patients seeking care at teaching dental clinics.
A cross-sectional study was carried out in 331 subjects between 18 and 85 (45.37 +/- 13.85) years of age seeking dental care in dental clinics of the Universidad Autónoma del Estado de Hidalgo, from January 2009 to December, 2009. Data pertaining to age, sex, tooth number and the reason for extraction according to Kay & Blinkhorn were analyzed with non-parametric tests.
779 extractions were undertaken. The main reason for extraction was dental caries (43.1%), periodontal disease (PD) (27.9%), and prosthetic reasons (21.5%). There was no significant difference across sex for reasons of extraction (p > 0.05). Significant differences (p < 0.001) were found for age (extraction due to periodontal disease increased with age); in patients attending in a single visit vs. patients attending a series of dental appointments (caries reasons were more common in patients having a single appointment vs. PD in those attending a series of appointments); for type of teeth (upper, posterior, and molars were extracted primarily because of caries, while lower, anterior and incisors were more often extracted because of PD).
Dental caries was the most common reason for tooth extraction, followed by periodontal disease. Differences in the reasons for extraction were observed across patient characteristics and type of tooth.
拔牙是口腔外科最常见的手术之一。本研究的目的是确定在教学牙科诊所就诊的成年患者拔牙的原因。
2009年1月至12月，对331名年龄在18至85岁（45.37±13.85）之间、在伊达尔戈州自治大学牙科诊所寻求牙科治疗的受试者进行了一项横断面研究。使用非参数检验分析了与年龄、性别、牙齿数量以及根据凯和布林克霍恩提出的拔牙原因相关的数据。
共进行了779次拔牙。拔牙的主要原因是龋齿（43.1%）、牙周病（27.9%）和修复原因（21.5%）。拔牙原因在性别上无显著差异（p>0.05）。在年龄方面发现了显著差异（p<0.001）（因牙周病拔牙的比例随年龄增加）；在单次就诊患者与多次就诊患者之间（龋齿原因在单次就诊患者中更常见，而牙周病在多次就诊患者中更常见）；在牙齿类型方面（上颌牙、后牙和磨牙主要因龋齿拔除，而下颌牙、前牙和切牙因牙周病拔除的情况更常见）。
龋齿是拔牙最常见的原因，其次是牙周病。在患者特征和牙齿类型方面观察到了拔牙原因的差异。
