Filter by:Enamel abrasion and stain removal efficacy of two whitening toothpastes
Aim of the Study: This study will compare between injectable flowable composite (Beautifil flow plus x) and high viscosity glass ionomer (Equia Fil) by ART caries preventive protocol in high caries risk patients receiving chemotherapy and/or radiotherapy
The aim of this study is to investigate the stain removal efficacy of 2 experimental anti-dentin hypersensitivity (DH) dentifrices with four and eight weeks twice daily use. A daily use, regular fluoride dentifrice will be included as a reference dentifrice.
Dental staining may interfere with compliance with chlorhexidine mouth rinse use Thus, developing strategies to control tooth staining associated with chlorhexidine use may be relevant for improving compliance. Thus, a new anti-staining toothpaste formulation (Dentaid, Barcelona, Spain) has been recently developed, aiming to interfere with the development of extrinsic staining associated with chlorhexidine use (preventive action), but also with the capacity of removing staining already formed. For that, the proposed formulation includes hexametaphosphate, tripolyphosphate and polyvinylpyrrolidone (PVP), within its ingredients. Thus, it may be relevant to test the efficacy of this new anti-staining toothpaste formulation in two consecutive randomized clinical trials (RCTs). Objectives The primary objective of these RCTs will be to evaluate the capacity of preventing tooth staining, associated with the use of a chlorhexidine mouth rinse, adjunctive to subgingival instrumentation (step 2 of periodontal therapy) (RCT #1). As secondary objective, the capacity of eliminating or reducing tooth staining already present will be assessed (RCT #2).
Aim of this study will be conducted to compare the shade matching and clinical performance of shade blocker versus chameleon effect of two single-shade of universal resin composite in class IV restorations over 1 year evaluation period
The aim of the present study was to investigate the relationship between the presence of black tooth stain (BS) and dental caries incidence, dental plaque scores and to examine the colonization of Streptococcus mutans, Lactobacillus spp., Actinomyces spp. and Capnocytophaga spp. in dental plaque samples with or without BS. The socioeconomic status of the family, the oral hygiene and dietary habits of the children, medical and dental history of the children were also compared between two groups.
The objective of the present study was to compare the effects of reduction of extrinsic stains between a commercially available Oclean electric toothbrush and Oral B manual toothbrush.
The aim of the study is to assess the efficacy of Blanx Black Toothpaste against extrinsic stains of teeth. Patients who sign the informed consent will participate to the study. At the baseline, the collection of Plaque Index, modified Lobene index and Bleeding Index will be performed, giving the instruction for a proper home oral hygiene. Professional supragingival and subgingival dental hygiene with piezoelectric will be performed. Then, patients will be randomly divided into two groups: - Trial Group will use Blanx Black Toothpaste (2 minutes brushing) twice a day for the all the study duration; - Control Group will use Colgate Sensation White Toothpaste (2 minutes brushing) twice a day. Patients will be reevaluated after 10 days, after 1 month and after 3 months, collecting again the indices and improving home oral care.
The aim of the present study is to evaluate the clinical outcomes (marginal discoloration, marginal adaptation, gingival health, debonding and patient satisfaction) of translucent zirconia crowns bonded by TheraCem (MDP, calcium and fluoride releasing) self-adhesive resin cement compared to multilink self-adhesive resin cement.
Conservatism is considered the main concern in any treatment plan, the feather edge preparation design of laminate veneers have been introduced yet clinical studies are lacking to evaluate their clinical performance.The aim of this study is to evaluate the effect of the two different preparation designs on the functional and esthetic outcome of laminate veneers in terms of marginal adaptation, retention, fracture, marginal discoloration and patient satisfaction
