【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x~2检验。结果:下颌第二磨牙龋坏多始发于(牙合)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,(牙合)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(牙合)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]:Objective: to analyze the origin and severity of dental caries in mandibular second molars and its relationship with sex, age and eruption of mandibular third molars. Methods: 481 patients with dental caries of mandibular second molar were investigated by clinical and X-ray examination. The results were tested by SPSS 13.0 software package. Results: the dental caries of mandibular second molars were mostly found on the (occlusal) surface and the distal adjacent surface, followed by the buccal surface, with the incidence of 33.833.2 and 24.4cm; the dental pulp was the most involved, accounting for 49.7%; deep caries, shallow and moderate caries accounted for 31.7g / 18.6; male, There was no significant difference in the distribution of female dental caries in general, age had a significant correlation with the distribution and severity of dental caries in mandibular second molars, and with the increase of age, dental caries on the (occlusal) and distal adjacent surfaces increased and the degree of caries increased. The eruption of mandibular third molars had a significant effect on dental caries of mandibular second molars. Conclusion: the primary dental caries of the second mandibular molars are mostly on the (occlusal) and distal adjacent surfaces, the degree of caries is serious, the age, the eruption status of the third mandibular molars is closely related to the dental caries. Prophylaxis of abnormal eruption of mandibular third molars and regular examination are effective measures for prevention and early treatment of dental caries of mandibular second molars.
