Objectives: This study was carried out to investigate the caries resistant effect of fluoride by dental polishing
prior to fluoride application in vitro.
Methods: Artificial caries lesion was made on the surface of specimen enamel taken from cow’s permanent cuspid on the part of labial surface after resin embedding and polishing. Artificial dental plaque was formed on the 72 dental specimen with 25~45 VHN(Vickers Hardness Number) which were divided into three groups(fluoride varnish, APF gel, control) with dental polishing and without polishing respectively. Fluoride varnish and APF gel group with 20 second polishing or without polishing were immersed in the artificial saliva respectively. Control group with or without polishing were immersed in the artificial saliva.
Results: 1. Significant difference was not found by fluoride varnish between polishing group and non polishing
group (p>0.01). 1) polishing group. The changes of Vickers Hardness Number(VHN) were 14.49±13.73. 2) non-polishin group. The changes of VHN were 11.67±5.39. 2. Significant difference was not found by APF gel between polishing group and non polishing group (p>0.01). 1) polishing group. The changes of VHN were 8.48±8.37. 2) non-polishing group. The changes of VHN were 5.32±2.59.
Conclusion: Showed no significant difference between polishing group and non-polishing group regardless of
fluoride materials (fluoride varnish, APF gel).
