Abstract

Chlorine levels and pH - receive much attention in the swimming world as they determine whether the pool water will be people - friendly that are safe, comfortable and enjoyable for swimmers or causing irritation and negative effects on the body. Restorative material samples were prepared for testing microhardness and surface roughness. A total of 160 specimens were prepared for this study. They were divided into two main groups ( Composite and compomer ) each group 80 specimens. Each group was divided into four subgroups according to pH of chlorinated water ( 7.5, 6.5, 5.5 and 4.5 ) ( Slightly alkaline, slightly acidic, medium and highly acidic ) each group 20 specimens. Each group was further classified into two classes according to the frequency of immersion ( Regular = 2hours/day and intensive = 4hours/day ). Each class was divided according to the testing procedure ( Microhardness or surface roughness ) into two equal subclasses. The subgroup placed in pH 7.5 was used as a control as recommended by many investigators.
Microhardness and surface roughness of each specimen were tested before and one month after immersion in chlorinated water. From the results, it was found that there is a linear direct correlation between PH value and microhardness of the tested hybrid resin composite and compomer sample. A reverse linear correlation exists between PH values of chlorinated water and surface roughnssof hybrid composite and compomer; the lower the PH value the greater the surface roughness. The effect of PH of chlorinated water on surface roughness is more significant with hybrid composite than of compomer.
