Effectiveness of Carisolv compared with sodium hypochlorite and calcium hydroxide

Abstract

The aim of this study was to compare the effectiveness of Carisolv with that of two other alkaline substances: NaOCl and Ca(OH)2. Sixty extracted teeth were randomly divided into three groups and split down the center of a carious lesion. In group I, one half of the cavity was excavated with NaOCl (0.5%, pH 11.7), the corresponding half with Ca(OH)2 (pH 12.4); in group II with NaOCl and Carisolv; and in group III with Ca(OH)2 and Carisolv (n = 20 in each case). Carisolv hand instruments were used. Histological specimens were subsequently produced from all cavities and analyzed with a light-microscope following Mallory-Azan staining. The thickness of the remaining caries was measured (< 1 mm or > 1 mm) and the locations were recorded. The data were statistically evaluated using the chi-square test. In group I, 50.5% of the specimens treated with NaOCI and 48.7% treated with Ca(OH)2 were evaluated to be caries-free. The results in group II were NaOCl 61.5% and Carisolv 75.4% caries-free, and in group III Ca(OH)2 61.2% and Carisolv 73.9%. No statistically significant differences were found between NaOCl and Ca(OH)2 excavation (group I: p = 0.89). Compared to NaOCl and Ca(OH)2, Carisolv produced significantly better results for chemo-mechanical caries removal (groups II + III: p < 0.05). In the NaOCl and Ca(OH)2 treated specimens, carious layers with a thickness >1 mm were found significantly more often than in the Carisolv-treated specimens (groups II + III: p < 0.05), whereas there were no differences between NaOCl and Ca(OH)2 excavation (p = 0.06). There were no statistically significant differences in the location of the remaining caries in any of the groups (p > 0.05).

Examination of caries‐affected dentin and composite‐resin interface after different caries removal methods: A scanning electron microscope study

“…Banerjee et al stated that the use of natural dentin carious lesions should be considered instead of the artificially induced carious lesions when evaluating clinical operative techniques in in vitro studies (Banerjee et al, 2000). Variables such as the size, shape, depth, and localization of natural carious lesions may have an impact on the excavation results, thus, this effect should be minimized (Bannerjee & Watson, 2000; Dammaschke et al, 2005). In this study teeth with extensive approximal caries lesions which did not reach the pulp tissue were chosen (Dablanca‐Blanco et al, 2017).…”

Microindentation hardness and calcium/phosphorus ratio of dentin following excavation of dental caries lesions with different techniques

“…When evaluating clinical operative techniques in in vitro studies, it has been stated that the use of natural dentin carious lesions should be considered instead of artificially-induced carious lesions (Banerjee et al 2000 ). However, the influence of the variables such as the size, shape, depth and localization of natural carious lesions on the excavation results should be minimised (Banerjee et al 2000 ; Dammaschke et al 2005 ). In order to standardize these variables, only the permanent teeth with occlusal carious lesions into the middle third of the dentin detected on the radiograph were included in this study.…”
