[Microbiological investigation of supragingival dental plaque in patients treated with porcelain jacket and gold veneered resin crowns].
The majority of periodontologists agree that the primary aetiological factor of periodontal disease is dental plaque. The purpose of the study was to investigate the accumulation of dental plaque on the with porcelain jackets and gold veneered resin crowns, and to correlate these findings with the data obtained on the uncrowned control teeth in the same patients. The qualitative analysis of microorganisms in dental plaque did not show a great difference between porcelain jacket and gold veneered resin crowns. However, a high difference was found in the quantitative accumulation of microorganisms in the mature dental plaque (considerably less on porcelain jacket crowns). These findings indicate that dental porcelain is less susceptible to accumulation of bacterial plaque in comparation to resin and even to hard tooth structures.
