ABSTRACT
The aim of this study was to investigate the relationship between several parameters of saliva and erosive wear in adolescents. (Un-)stimulated saliva was collected from 88 adolescents with erosion and 49 controls (age 16 ± 1 years). Flow rate, pH and buffer capacity were determined immediately. Total protein content, carbonic anhydrase VI, amylase, albumin, calcium, phosphate, urea, sodium, chloride and potassium were measured at a later time. Unstimulated flow rate was found to be significantly lower in subjects with erosive wear (p = 0.016). The chloride concentration in unstimulated saliva was found to be significantly higher in the erosion group (p = 0.019).

A 29-year-old woman consulted her dentist about a localgingival swelling which bled during tooth-brushing and had been present for 1 year. In the differential diagnosis, epulis gravidarum, a peripheral giant cell lesion, and peripheral ossifying granuloma were considered. After surgical removal, histopathological examination revealed a peripheral giant cell lesion. The presence of a peripheral giant cell lesion requires thorough excochleation of the underlying bone. If the bone is cleaned thoroughly, recurrence is rare.
