摘要/Abstract

摘要： 目的: 统计分析下颌第二磨牙龋坏始发部位及严重程度, 并分析其与性别、年龄及下颌第三磨牙萌出状况的关系。方法: 采用临床与X线检查对481例下颌第二磨牙龋坏患者进行统计调查, 应用SPSS 13.0软件包对结果进行χ2检验。结果: 下颌第二磨牙龋坏多始发于面和远中邻面, 其次为颊面, 发生率分别为33.8%、33.2%、24.4%;累及牙髓的龋坏最多, 占49.7%, 深龋、浅中龋分别占31.7%、18.6%;男、女性别在龋坏部位分布总体上无显著差异;年龄与下颌第二磨牙的龋坏部位分布及严重程度有显著的相关性, 随着年龄增大, 面和远中邻面龋坏增多, 程度加重;下颌第三磨牙萌出状况对下颌第二磨牙龋坏影响显著。结论: 下颌第二磨牙始发龋坏牙面以面及远中邻面最多, 龋损程度严重, 年龄、下颌第三磨牙萌出状况与龋坏状态关系密切。预防性拔除异常萌出的下颌第三磨牙及定期检查, 是预防和早期治疗下颌第二磨牙龋坏的有效措施。

Abstract: PURPOSE: To collect the cases which have caries on the mandibular second molar and analyze the caries status and correlative factors. METHODS: Patients treated in the Department of Endodontics in West China Hospital of Stomatology were randomly collected. The baseline information, primary sites and severity of dental caries on the mandibular second molar, and eruption pattern of the mandibular third molar were recorded. The data was analyzed with SPSS13.0 software package. RESULTS: Four hundred eighty-one patients including 227 males and 254 females were collected. Caries on the mandibular second molar starting from the occlusal, distal proximal and buccal surfaces accounted for 33.8%, 33.2% and 24.4%, respectively. Caries involving dental pulp (49.7%) were significantly more than deep and shallow to moderate caries (31.7% and 18.6%). Gender was not correlated with the site and severity of caries. However, impacted mandibular third molars and age were significantly related to both caries site and severity. CONCLUSIONS: Occlusal and distal proximal surfaces are the most predisposed sites to have caries on mandibular second molar. Impacted mandibular third molar and age are significantly related to caries of mandibular second molar.
