The incidence and composition of salivary stones (sialolithiasis) in Iran: analysis of 95 cases--a short report.

In a 3 year period 95 patients with sialolithiasis were studied, giving an annual incidence of 7.3 per 1000 admissions. The male to female ratio was 2.5:1. Salivary gland stones comprised 73.68 per cent (N = 70 patients). Chemical analysis of calculi taken from 88 patients, showed that 89.77 per cent (N = 79 patients) were with phosphate salts stones, 7.98 per cent (N = 7 patients) were with oxalate salts, and 2.27 per cent (N = 2 patients) were with urate salts. Salivary gland infection was present in 91.57 per cent (N = 87 patients) of whom 75.86 per cent (N = 66 patients) and 24.14 per cent (N = 21 patients) were females. A high ambient temperature and dehydration with poor oral hygiene are probable causative factors.
