Abstract
Background: Tooth extraction is one of the dental treatments which should be considered the last option; extraction of tooth is the removal of teeth from the dental alveolus (socket) in the alveolar bone. Extraction of permanent teeth in adult and children should be performed for several reasons including dental caries, periodontal and gingivitis disease, crowded, perapical lesion, trauma, impacted wisdom teeth, failed root canal treatment, and orthodontic reasons. The oral health requires the permanent teeth retention as long as possible because the teeth are important not only for functional reasons but also esthetics. Objectives: The aim of this survey was to investigate the primary reason for extraction of the permanent teeth and its correlations with age, gender, and education level, as well as, identify the important predictors for dental caries in general dental centers in Mosul, Iraq. Subjects and Methods: The study was conducted over a period of 15 months; the sample consisted of (1254) patients, aged 9–70 years, who underwent tooth extraction. There were male and female patients. The frequency distribution was calculated using the 2 test, ANOVA and t test for differences in mean number of extracted teeth and the logistic regression model to evaluate the variables associated with reasons for tooth extraction. Results: A total of teeth were extracted from the patients. The highest rate (23.4%) of extraction occurred for those 51–60 years old. Males comprised (41.1%) of patients and had more teeth (48.1%) extracted than females (41.9%). Significant differences are found between teeth extraction and the levels of education. Tooth loss due to caries is (35.4%); periodontal gingivitis (24.4%); peri-apical lesion (16.7%); crowded (6.8%); root canal failure (7.4%), wisdom (6.1%), and trauma (3.2%). Tooth loss is an easily identifiable outcome that summarizes a complex suite of factors in an individual's history of dental disease and its treatment by dental services over a lifetime. Conclusion: The results of this survey indicated that dental caries and periodontal disease were the main reasons for tooth extraction in Mosul, Iraq. The majority of patients had incomplete secondary education or lower and had even more teeth extracted than patients having higher levels of education. The best predictors for tooth loss due to caries were age, gender, marital status, tooth type, and having had a previous extraction. However, the smoking status shows insignificant association with tooth loss.
