Loss of permanent dentition is often of great concern to patients, apart from the aesthetic consequences in the anterior region of the mouth, such loss has no natural form of replacement.
To determine the pattern of tooth loss among patients attending the Dental Clinic at a Nigerian teaching hospital.
The case files of patients who attended the Dental Clinic of Aminu Kano Teaching Hospital, Kano between January and December 2012 with one or more missing tooth were retrospectively analyzed. The information collected included age, gender, educational level, residential area, missing tooth/teeth and reasons for the loss. The data were analyzed using SPSS version 13.0 (Chicago, Illinois). A p-value of less than 0.05 was considered significant.
A total of 1100 missing teeth were recorded involving 960 patients within the period of one year. Males comprises 520(54.2%) and females 440(45.8%). The most predominant age group was the 21-30 years with a mean of 29.53 +12.41 years and this comprised 48.2% of the cases. Caries related extractions (65.6%) were the most common cause of tooth loss followed by periodontal disease in 13.1% of cases and symptomatic impacted tooth in 9.8%. Gender affects the etiology of tooth loss was significant with males having more tooth loss (X=52.93, df=6, P=0.001). There was a significant association between age and the pattern of tooth loss with tooth loss due to periodontal diseases occurring in the older age groups (X=1071.67, p=0.001).
Dental caries and periodontal diseases still remain the main causative factors for tooth loss in this environment, more common in men and rural dwellers.
恒牙缺失常常让患者极为担忧，除了口腔前部的美学影响外，这种缺失没有自然的替代方式。
确定一家尼日利亚教学医院牙科诊所患者的牙齿缺失模式。
回顾性分析2012年1月至12月期间在卡诺阿明努·卡诺教学医院牙科诊所就诊的有一颗或多颗牙齿缺失患者的病历。收集的信息包括年龄、性别、教育程度、居住地区、缺失牙齿及缺失原因。使用SPSS 13.0版（伊利诺伊州芝加哥）对数据进行分析。p值小于0.05被认为具有统计学意义。
在一年时间内共记录到1100颗缺失牙，涉及960名患者。男性520名（54.2%），女性440名（45.8%）。最主要的年龄组为21 - 30岁，平均年龄29.53 ± 12.41岁，占病例的48.2%。与龋齿相关的拔牙（65.6%）是最常见的牙齿缺失原因，其次是牙周病，占13.1%，有症状的阻生牙占9.8%。性别对牙齿缺失病因有显著影响，男性牙齿缺失更多（X = 52.93，自由度 = 6，P = 0.001）。年龄与牙齿缺失模式之间存在显著关联，牙周病导致的牙齿缺失发生在年龄较大的组（X = 1071.67，p = 0.001）。
在这种环境下，龋齿和牙周病仍然是牙齿缺失的主要致病因素，在男性和农村居民中更为常见。
