Pattern of dental extraction in children in a Nigerian tertiary hospital.J Contemp Dent Pract. 2005 May 15; 6(2):80-90.JC
Changes that occurred in the pattern of tooth extraction in the last 13 years among a population of children in Nigerian were studied. The result of this study was then compared to that of a past study done in the same institution 13 years earlier. Information on age, gender, and indication of tooth extraction was collected prospectively from 379 consecutive patients who visited the outpatient Pediatric Dental Clinic for the first time during the year 2002. Results showed tooth extraction due to caries decreased, while there was an increase in tooth extraction from an apparent increase in orthodontic treatment needs. Acute necrotizing ulcerative gingivitis (ANUG), a significant cause of tooth loss in the last decade, decreased significantly. The pattern of deciduous tooth loss also changed as more anterior teeth were lost for orthodontic reasons in this present study. The pattern of tooth loss in the permanent dentition remains very similar to that of the past study, though more premolars were lost in the present study. There appears to be an increasing need for tooth extractions in orthodontic treatment for this population of children. The focus of planned dental health care provisions, treatment policies, and training emphasis in child dental care may need to shift to addressing orthodontic needs.
