Many studies about tooth loss have been reported, but until recent years, no great effects in the prevention of tooth loss has been achieved. We hoped this study served as data to help prevent the loss of tooth and to design the future dental treatment plan. We studied the 14,953 cases of tooth extractions except deciduous and supernumerary teeth, of the 7,782 patients (3,846 males and 3,936 females), over 10 years old, during 1987 to 1989, at the department of oral surgery, Seoul National University Hospital. We analysed the cases according to tooth type, age, sex and reason for extraction and obtained the data about to the tooth mortality and the cause of tooth loss. The categories selected as reasons for extraction were dental caries, periodontal disease, impaction, prosthetic reason and other reasons, and the results of comparisons were as follows :
1. The average of tooth loss in male patients were ranged from 31.8 to 56.3 years and the mean age was 40.0 years, and in female patients, ranged from 29.6 to 59.7 years and the mean age was 38.2 years. Thus, the tooth loss in females was earlier than in males (P<0.01).
2. The average ages of tooth loss in maxillae were ranged from 31.8 to 49.3 years and the mean age was 41.6 years, and in mandibles, ranged from 30.7 to 56.9 years and the mean age was 38.2 years. Thus, the tooth loss in mandible was earlier than in maxilla (P<0.01).
3. The percentage of tooth loss by dental caries was 26.9% in male patients and 32.5% in female patients therefore, the tooth loss by dental caries were more common in female (P<0.01). And 37.6% in maxilla, and 24.1% in mandible, therefore, the tooth loss by dental caries were more common in maxilla than in mandible (P<0.01).
4. The percentage of tooth loss by periodontal disease was 37.8% in male patients and 31.0% in female patients, therefore, the tooth loss by periodontal disease were more common in male (P<0.01). And 32.0% in maxillae, and 36.0% in mandibles, therefore, the tooth loss by periodontal disease were more common in mandible than in maxilla (P<0.01).
5. The percentage of tooth loss by impaction or malposition was 23.6% in male patients and 25.0% in female patients, therefore, the tooth loss by impaction or malposition were more common in female (P<0.05). And 11.4% in maxillae, and 33.6% in mandibles, therefore, the tooth loss by impaction or malposition were more common in mandible than in maxilla (P<0.01).
6. The percentage of tooth loss by prosthetic reason was 4.2% in male patients and 5.0% in female patients, therefore, the tooth loss by prosthetic reason were more common in female (P<0.05). And 5.2% in maxillae, and 4.2% in mandibles, therefore, the tooth loss by prosthetic reason were more common in maxilla than in mandible (P<0.01).
