Ai. Abdalla et al., CLINICAL-EVALUATION OF GLASS IONOMERS AND COMPOMERS IN CLASS-V CARIOUS LESIONS, American journal of dentistry, 10(1), 1997, pp. 18-20
Purpose: To evaluate the 2-year clinical performance of two polyacid-m
odified resin composites and two resin-modified glass ionomers in Clas
s V carious cavities. Materials and Methods: A total of 120 Class V ca
vities were selected and 30 cavities were restored with one of two res
in-modified glass ionomer materials (Fuji II LC Improved and Vitremer)
and two polyacid-modified resin composites (Dyract and Compoglass) in
Class V carious cavities after 2 years. The restorations were clinica
lly evaluated after 1 and 2 years using the USPHS criteria. Results: O
ne-year findings revealed a significant difference in color match betw
een Vitremer and other materials (P < 0.05) and no significant differe
nce was found for the other criteria. Two-year results indicated a sig
nificant difference between resin-modified glass ionomers and polyacid
-modified resin composite materials. The difference between Compoglass
and Dyract was not statistically significant whereas the difference b
etween Vitremer and Fuji II LC was statistically significant. Caries w
as not recorded at any evaluation period.
