Abstract

Aim: A lot of herbal and medicated toothpastes having natural and antisensitivity properties are creating niches for themselves in the market. However, toothpaste containing high content of abrasives can be harmful to the teeth. The present in vitro study was conducted to assess the abrasiveness of three commercially available dentifrices on human-extracted anterior teeth on sound and demineralized enamel. Materials and methods: A total of 42 freshly extracted teeth were mounted on acrylic resin and randomly divided into three groups (group I, Colgate; II, Glister; and III, Dant Kanti). Each group consisted of one test tooth (partially) and one control tooth (completely) covered with nail varnish. The study had two phases. Phase 1—baseline average roughness (Ra) value was assessed with a profilometer of all the samples. Phase 2—further, teeth were immersed in the demineralizing solution for 4 days to allow the formation of an artificial carious lesion. Tooth brushing was performed by a customized automated toothbrushing model on all the teeth for 28 days. Ra value was again evaluated with Profilometer. Result: Data were analyzed, and a statistically significant result was observed with demineralized teeth in all three groups (p = 0.005). The intragroup comparison showed a significant difference with demineralized teeth of Colgate and Dant Kanti, (p =0.018) and (p =0.027), respectively. However, there was no significant difference in demineralized teeth of glister and sound teeth of all three groups. Conclusion: Glister was found to be the least abrasive of all three toothpastes, followed by Dant Kanti and Colgate. Clinical relevance: The particle size of the ingredients used in manufacturing toothpaste can lead to abrasion of the teeth. This, in combination with the hard bristles, can cause more harm to the teeth than good. The current study has compared the abrasive potential of three commercially available kinds of toothpaste. Hence daily use of these commercially available dental products should be used cautiously.
