This book was released on 2016 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-carious cervical lesions (NCCLs) can be defined as the loss of dental hard tissue near the cemento-enamel junction without bacterial involvement. Abrasion, erosion and abfraction have been mentioned as common etiological factors of NCCLs. Abrasion is the loss of tooth structure due to friction by materials such as toothbrushes or abrasives in toothpaste. In contrast, dental erosion is the loss of tooth structure driven by acids. Abfraction, on the other hand, starts due to the weakening of the tooth structure in areas of concentrated stress as a result of cuspal flexure from heavy and repeated occlusal loading, which progresses to dental hard-tissue loss. Purpose: The present study focused on the abrasion aspect of NCCLs. Specifically, it aimed to investigate the influence of dentifrice abrasivity and toothbrush stiffness on the development of NCCLs in vitro Hypothesis: NCCL development is affected by both the abrasive level of the dentifrice and the stiffness of the toothbrush, as well as their interaction. Materials and Methods: A total of 288 extracted human upper first premolars, free of any dental caries and root defects, were selected. The teeth were be cleaned with a hand periodontal scaler and randomly assigned into twelve groups (total of 24 teeth/group). Specimens were brushed in an automated toothbrushing machine, using simulated toothpaste slurries of varying abrasivity and toothbrushes of varying stiffness. This study examined three experimental factors: 1. Toothpaste abrasivity, at four levels: high, medium, low, and non-abrasive slurry (as negative control); 2. Toothbrush stiffness, at three levels: soft, medium, and hard; 3. Toothbrushing cycles at three levels: baseline, 35k, and 65k strokes. Specimens were analyzed by optical profilometry at baseline and after each brushing level. The response variable was the dentin volumetric loss, in mm3. All toothbrushes caused significantly higher tooth wear when associated to the high abrasive slurry, compared to medium- and low-abrasive slurries. Medium- caused more tooth wear than low-abrasive slurry, which in turn led to more tooth wear than the control. Hard and medium toothbrushes were not significantly different, but both caused significantly higher volumetric loss than Soft toothbrushes. There were no differences among toothbrushes, when used with the non-abrasive (control) and low- abrasive slurries. Overall, 35k strokes resulted in significantly less tooth volumetric loss than 65k.

Download or read book Toothpastes written by C. van Loveren and published by Karger Medical and Scientific Publishers. This book was released on 2013-06-19 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the mass-marketed introduction of fluoride in toothpaste in the 1950s, toothbrushing with paste became indispensable for good oral health. Both the industry and the dental profession had a shared interest in advocating the widespread correct use of good quality toothpaste. This publication starts with a general introduction on the purpose, history and composition of toothpaste. The following chapters deal with the clinical evidence of its effectiveness in caries prevention, reducing and preventing plaque, gin-givitis, halitosis, and calculus formation, facilitating removal and prevention of extrinsic stain, and preventing dentine hypersensitivity and erosion. Later chapters provide valuable information on the abrasiveness of the pastes, the substantivity of active ingredients in the oral cavity and the possible models to study the effectiveness of the pastes when full-scale clinical trials are not possible. The final chapter focuses on the frequency of toothbrushing and post-brushing rinsing behavior. The book provides indispensable information for dentists, dental students and community dental programs on whether toothpastes can be recommended to patients for specific aims and how to use them to obtain the best effect.

Download or read book Relative Dentrifrice Abrasivity on Dentin and Enamel written by Laura Marchetti and published by . This book was released on 1997 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The abrasive characteristics of six (6) brands of toothpastes on Enamel and Dentin material were assessed. Human teeth were sliced to expose the dentin surface and then polished using 3 æm and 0.25 æm diamond paste. The outside surface of the tooth (after slicing) was used "as is" for the enamel surface testing. The surface smoothness was evaluated prior to testing using a surface profiler and averaging four (4) to five (5) readings across the surface for each sample. The tooth slices were then embedded into the acrylic plate surface by routing out an area with a dental drill and using polymethylmethacrylate (PMMA) to adhere the teeth to the plate. An acrylic abrasion machine was used to brush each sample for 3000 strokes with each of the toothpastes being tested. At least three (3) samples of each material were used for each paste. The same type of medium stiffness brush was used for each test. The surface smoothness was then re-assessed using the surface profiler again averaging four (4) to five (5) readings across the surface. The data was statistically analyzed and ranked by abrasiveness.

Available in PDF, EPUB and Kindle. Book excerpt: Les dentifrices solides connaissent un succès de plus en plus important auprès des acheteurs cependant il n'existe que très peu d'études concernant leur interaction avec les tissus dentaires. L'objectif de ce travail est d'évaluer le pouvoir abrasif de 3 dentifrices solides sur la dentine. Pour cela une étude in vitro a été réalisée. Cinq groupes de dents ont été brossés soit avec un dentifrice solide, soit un dentifrice classique du commerce, soit sans dentifrice ; simulant un brossage de 6 mois. Une mesure par profilométrie avant et après brossage de différents paramètres de rugosité a été effectué pour évaluer le pouvoir abrasif. Aucune différence significative n'a été montré dans cette expérience. Les dentifrices solides testés dans cette étude ne seraient pas plus abrasifs par rapport au dentifrice témoin ni même sans l'utilisation de dentifrice.
