Effect of cavity form on the durability of glass ionomer cement restorations in primary teeth: a three-year clinical evaluation.
The effect of cavity form on the durability of  glass ionomer cement restorations in primary molars was studied in a clinical , intraindividual , three-year longitudinal study . Proximal restorations were placed in either a microcavity or a modified Black 's Class II cavity with rounded internal and external angles . A total of twenty-eight pairs were assessed . After two years the cumulative failure rate was 16 percent for each of the cavity types and after three years 25 percent for the microcavity and 32 percent for the modified Black 's Class II cavity . No statistical difference was found in the longevity of the restorations placed in the two different types of cavities
