Description

<p>It has been pointed out that the granule components in toothpaste penetrate and remain in the peri-implant sulcus, where they may cause inflammation of the peri-implant tissue. The aim of this clinical study was to evaluate the effect of penetration of granule components on inflammation of peri-implant tissue in patients visiting for maintenance after implant treatment, by investigating the condition of peri-implant tissue and performing the tooth-brushing test using toothpaste mixed with a granule component.</p><p>Fifty-five patients and 145 implants for supporting 78 screw-retained superstructures of the molar sites were investigated. The adhesion of dental plaque around the superstructure and the presence of inflammation of peri-implant tissue were evaluated. Additionally, the morphology of peri-implant tissue was measured. In the users of toothpaste with a granule component, residual granules of peri-implant sulcus were observed. After performing the tooth-brushing test using a toothpaste with granule component, the penetration of granules into the peri-implant sulcus was investigated. From the observation survey and the tooth-brushing test, the relationship among the presence of inflammation of peri-implant tissue, the morphology of the peri-implant tissue and the invasion of granule components was evaluated.</p><p>In 19 patients who used the toothpaste with granule components daily, granule components remained in 14 implants of 6 patients. There was no correlation with the presence of inflammation and the remnants of granule components. In the tooth brushing test, 22 implants in 13 patients showed penetration of granule components. No correlation was found with the presence of inflammation and the penetration of granule components.</p><p>From the results of this study, it was inferred that there was little relation between the penetration of the granule components of toothpaste and the inflammation of the peri-implant tissue.</p>
