Background
Few related surveys about reasons for tooth extraction was shown in mainland China. Our aim was to investigate the primary reasons and main pattern for extractions among patients presenting at a hospital of stomatology in Guangzhou, China.
Methods
This descriptive cross-sectional study was conducted over a period of 3 months, 2000 patients who underwent tooth extraction were recorded and analyzed by age, gender, the tooth type and the extraction reasons. Chi-square test was used to examine the differences in the extraction reasons between different genders, age groups and tooth types.
Results
A total of 3106 teeth were removed from 2000 patients, with an age ranging from 6 to 91. This study revealed details of extraction reasons and suggested that dental caries (25.42%) was the main reasons for tooth extraction and pointed out preventive extraction of third molar (19.89%) had displaced periodontal diseases (12.89%) as the dominant reason for extractions. Overall, third molar was the most frequently extracted tooth (1567). Significant statistical differences were found among different age groups, genders and tooth types for tooth extraction reasons (p༜0.05). For example, caries was the main reason for tooth extraction in 30–59 years old patients, while 20–29 years old patients asked for preventive extraction of third molar teeth mostly. Posterior teeth were mostly removed because of caries and periodontal disease was the leading cause for anterior teeth extraction.
Conclusions
We found the primary reasons and the new patterns for tooth extraction among patients in Guangzhou. It was proposed for the first time that the dominant reason for extractions was preventive extraction of third molar. Our finding could help to put forward some predictors and adjust the preventive strategies in oral disorders.
