Abstract
The purpose of this study was to compare the tooth wear in function of the use of different commercial herbal toothpastes through the analysis of Optical Coherence Tomography (OCT). Twenty bovine teeth were obtained and distributed in 4 groups (n = 5) according to the dentifrice used: G1: Captive Nature (Chamomile, Xylitol, Juá and Salvia); G2: Suavetex Content (Turmeric); G3: Colgate Triple Action (positive control); G4: distilled water (negative control). The samples were painted in the half of the fragment with nail polish so that only half of the fragment was brushed. The simulated brushing (20,000 cycles) was performed with linear movements, under static axial load of 200g and speed of 4.5 cycles per second. After this step, an analysis was performed through OCT and and the images obtained were evaluated to identify possible changes in the specimen surface. According to the qualitative analysis of the OCT images, enamel wear was not observed, since all measurements were null. Regarding the evaluation of dentin, surface wear was observed in all groups except G4, but G3 had the highest number of samples with surface wear around 21.32%. All dentifrices had abrasive wear on the dentin surface to a greater or lesser extent, but there was no wear on the enamel surface.
Highlights
The expansion of consumption of products developed with natural bases is associated with the values of contemporary society which are related to quality of life in general, beauty, well-being and pleasure, aesthetics, youth and healthy appearance
Dentifrices are used to reducing caries, gum and periodontal diseases, dental calculus, dentin hypersensitivity and halitosis (Jardim; Alves; Maltz, 2009; Sanz et al, 2013)
Knowing that the indiscriminate use of toothpaste associated with the mechanical action of the toothbrush has been associated with an increased prevalence of abrasion of the teeth’s hard tissues (Wiegand; Schlueter, 2014; Savage et al, 2019), this study aims to comparatively assess the tooth wear due to use of different toothpastes through Optical Coherence Tomography (OCT) analysis
Summary
The expansion of consumption of products developed with natural bases is associated with the values of contemporary society which are related to quality of life in general, beauty, well-being and pleasure, aesthetics, youth and healthy appearance These values, among other factors, could be obtained from the use of ingredients and formulations from nature (Vecino et al, 2017; Mellou; Varvaresou; Papageorgiou, 2019). Dentifrices are associations of substances that, used in daily brushing, remove exogenous deposits adhered to teeth, making them more resistant to microbial attack as they have the function of enhancing toothbrush’s mechanical action They are commercially presented in several physical forms, such as paste, powder and gel, highlighting the paste as the most popular formulation, followed by gel (Sanz et al, 2013; Shetty et al, 2017; Resende et al, 2019). Dentifrices are used to reducing caries, gum and periodontal diseases, dental calculus, dentin hypersensitivity and halitosis (Jardim; Alves; Maltz, 2009; Sanz et al, 2013)
