Study regarding the erosive potential of water from
swimming pools on dental hard tissues

Abstract:

This research aimed to assess water pH from 8 swimming pools (sporting, recreation, individual) and to evaluate the erosive potential of pool chlorinated water on dental enamel as well as the protective effect of remineralisation GC Recaldent MI Paste to counteract erosion (cuantification of surface roughness by profilometry). The assessment of chlorinated water erosive potential was performed in vitro on 50 dental samples obtained by sectioning of teeth extracted from orthodontic purposes and randomly divided in five groups (four study groups, control group). The study groups (groups I, II, III, IV) were submitted to demineralisation cycles, respectively (groups II, IV) to remineralisation with GC Recaldent MI Paste. The determination of water pH was performed using pH-meter Checker (HANNA), and the wear of dental surfaces submitted to erosive cycles was determined by profilometry method using rugosimeter TAYLOR HOBSON Surtronic 25. The analysis of results shows acid pH values (under 7) for water in all 8 swimming pools, demonstrating an erosive acid potential. Accordingly to profilometry test, the erosive effect of chlorinated water from swimming pools, is direct related to exposure duration (higher for group I, corresponding to professional swimmers, lower for group III, corresponding to non-professional swimmers). Significant statistical differences were found between erosion values for groups I (professional swimmers) and group III (non-professional swimmers). In the study groups submitted to remineralization therapy (group II, IV), it was recorded a tendency to counteract the erosive effect, with significant statistical differences between groups. Keywords: dental erosion, remineralisation, enamel, profilometry, swimmers, pH
