Oral health status and alveolar bone loss in treated leprosy patients of central India.

A descriptive cross sectional study was carried out, in a group of 160 leprosy patients treated with multi drug therapy. The patients with age group of 25 to 60 year were considered. Out of 160 patients 50 patients were selected by simple random sampling technique for radiological assessments. Intra-oral periapical radiographs (6 for each patient) were taken. The paralleling long cone technique was used and radiographs were attached with grids so as to enable measuring the bone height. The grid was spaced in 1 mm marking and placed directly over the film. Clinical examination revealed that Prevalence of dental caries was 76.25% and periodontal disease was 78.75%. Mean DMFT score was 2.26. Mean OHI-S score was 3.50. Score for Gingival index was 1.60 and average loss of gingival attachment was 1.2 mm. Radiographic findings showed mean alveolar bone loss in maxillary anterior region to be 5.05 mm and in maxillary posterior region it was 4.92 mm. Alveolar bone loss in mandibular anterior region was 4.35 mm and in mandibular posterior region was 5.14 mm. Overall Dental Health Status of the leprosy patients was poor and needed more attention for dental care. There was also an increase in the alveolar bone loss, which was generalized. This bone loss could be due to advance stage of the disease or late approach to rehabilitation center, these patients also had peripheral neuropathy leading to hand and feet deformity in the form of claw hand or ulcer on hand, making maintenance of oral hygiene difficult.
