Etetafia MO, Okoro S

Abstract


Introduction: The study was carried out to determine the pattern of loss of teeth in Delta State, a region in the Niger Delta. The design was a retrospective review of medical records of patients who visited the hospitals and had dental extractions. The setting is the four dental centres located in the four
largest state government hospitals namely, Warri, Ughelli, Sapele and Agbor. All patients that had dental extractions between January 2003 and December 2005 were selected and included in the study.

Materials and methods: A three year retrospective review of patients' records from four dental centres in Delta State was conducted. Data were entered into SPSS statistical software and results presented as simple tables and proportions.
Results: From the four dental centres in the State a total of 8,066 teeth were extracted from 6,053 patients aged 3 to 100 years giving a mean tooth loss of 1.4. The age group 21-30 constituted 1,880(31.1%) of the patients followed by age group 31-40 with 1,069(17.7%) and then age group 11-20 with 908(15.0%) patients. Lower molar teeth (42.4%) were lost most often followed by upper molars (22.7%), upper anteriors (11.1%) and upper premolars (6.4%).

Conclusion: Molar teeth were lost more often than any other teeth in the mouth. Patients in the third decade of life had more dental extractions than other age groups. The pattern of tooth loss in this study is in line with other similar studies within and outside the country.
