Frequency of alveolar osteitis (dry socket) at Kenyatta National Hospital Dental Outpatient Clinic--a retrospective study.

The objectives of this study were to determine the frequency of alveolar osteitis at Kenyatta National Hospital (KNH), most affected age group and the reasons for underlying extractions. Out of 8,393 extractions 273 (3.3%) developed alveolar osteitis. 98.5% of the teeth that developed alveolar osteitis were molars and premolars. 52% of the patients that developed alveolar osteitis were females and 48% were males. The mandible was more affected than the maxilla. The percentage distribution of alveolar osteitis according to age groups 10-19 year, 30-39 years, 40-49 years, 50-59 years and 60-69 years were 6.2%, 53.1%, 23.8%, 5.5%, 4.8% and 2.9% respectively. On the average, patients reported with alveolar osteitis 5.7 days following extraction. Out of 8,393 extractions, 72.5% were due to dental caries, 18% were due to periodontitis and the rest were due to other causes. It was concluded that the frequency and average, patients reported with alveolar osteitis 5.7 days following extraction. Out of 8,393 extractions, 72.5% were due to dental caries, 18% were due to periodontitis and the rest were due to other causes. It was concluded that the frequency and pattern of development of a alveolar osteitis at KNH was similar to that reported in developed countries.
