Objectives: To investigate the prevalence and factors associated with dentin hypersensitivity (DH) and non-carious cervical lesions (NCCLs).
Methods: The analytical cross-sectional study included 157 participants aged between 18 and 45 years, who were clinically examined and answered a questionnaire related to their lifestyle and daily habits (diet, parafunctional habits, temporomandibular disorders, general and oral health) and the Beck Anxiety Inventory. A descriptive analysis of the prevalence of DH and NCCL was performed, both at the individual level and considering the distribution among the teeth.
Article Synopsis
- The study investigates the role of immediate dentin sealing (IDS) in indirect restorations, aiming to determine if it should be a standard practice based on evidence from randomized clinical trials (RCT).
- A literature review identified data from four RCTs, indicating that IDS can reduce hypersensitivity one week after restoration cementation but shows no difference in longevity of the restorations.
- The conclusion suggests that while IDS can be beneficial, especially for patients at risk of sensitivity, it should be viewed as an optional step rather than a mandatory one.
Objectives: The present study aimed to evaluate the desensitizing effect of toothpaste for sensitive teeth on patient tooth sensitivity and on bleaching efficacy of the 38% hydrogen peroxide bleaching agent used for in-office bleaching compared to a regular toothpaste in a randomized clinical trial.
Methods And Materials: Forty-eight patients having maxillary right central incisors with darkness greater than A1 were selected for the present double-blind randomized clinical trial. Patients were randomly allocated into two groups: the placebo group, which used regular toothpaste, and the experimental group, which used sensitivity toothpaste.
Article Synopsis
- Antimicrobial photodynamic therapy (A-PDT) is an adjunctive method to enhance root canal disinfection by targeting intracanal biofilm.
- A systematic review included 27 studies that were analyzed for the effectiveness of PDT when combined with traditional endodontic procedures.
- While PDT generally decreased bacterial viability in most studies, the lack of precise quantification and biases in the research limited the robustness of the conclusions.
The aim of this study was to evaluate the degree of conversion, cytotoxicity, solubility and pH of photopolymerizable calciumbased cements submitted to preheating. The degree of conversion was analyzed by Fourier transform infrared, cytotoxicity by the MTT test and solubility through loss of mass. The data were subjected to statistical tests (ANOVA / Tukey's, p<0.
