Background And Aim: Dentinal hypersensitivity is a relatively common problem experienced in clinical dental practice and is characterized by short, sharp pain in response to stimuli such as tactile, thermal, evaporative, osmotic, or chemical. Several agents and treatment modalities have been used in the treatment of this condition. This study was conducted to compare the efficacy of four commercially available toothpastes in the reduction of dentinal hypersensitivity (DH), based on the hypothesis that calcium sodium phosphosilicate (CSPS) group had a better efficacy of the four.
Settings And Design: This study design was a prospective, single-blind, randomized, parallel clinical design.
Subjects And Methods: A total of 160 cases (93 males and 67 females; aged 20-60 years) were randomly divided into four groups: Group 1 - toothpaste containing 5% potassium nitrate; Group 2 - toothpaste containing 5% CSPS (NovaMin); Group 3 - toothpaste containing 10% strontium chloride; and Group 4 - a herbal formulation. The patients' DH scores for tactile, thermal, and evaporative stimuli were recorded on a visual analog scale at baseline, 2 weeks, 1 month, and 2 months.
Statistical Analysis Used: The data were analyzed with Wilcoxon signed-rank test, Kruskal-Wallis test, and Mann-Whitney U-test (P < 0.05).
Results: The four desensitizing kinds of toothpaste containing different active agents were effective in relieving dentinal hypersensitivity. However, CSPS group showed a better clinical response at the end of 2 months.
Conclusions: The CSPS group showed a better reduction in the symptoms of DH.

Dentin hypersensitivity (DH), marked by exposed dentinal tubules, presents as a sharp toothache triggered by stimuli and subsides when the stimuli are removed. To address the limitations of current commercial desensitizers in terms of acid resistance, friction resistance, and stability, a black phosphorus nanosheet-composited methacrylate gelatin hydrogel (GelMA/BP) is developed for DH treatment, leveraging the synergistic effects of photothermal therapy and biomineralization. Incorporating the BP nanosheet provided GelMA/BP with a stable photothermal response and the continuous release of phosphate anions, which blocked dentinal tubules by converting light energy into heat and initiating biomineralization.

Background: For a periodontist, treating recession is always a proud moment and a challenging task. The current trial aimed at comparing and clinically evaluating semilunar coronally repositioned flap (SCRF) and coronally advanced flap (CAF) procedures combined with platelet-rich fibrin (PRF) in the management of Miller's Class I recession defects.
Materials And Methods: Thirty-six recession sites were randomly divided into the CAF or SCRF groups.

Teeth undergo continuous demineralization and remineralization influenced by dietary acid and saliva. Excessive dietary acid attack disrupts this balance, exposing dentin tubules and causing dental hypersensitivity (DH). Due to low acid resistance, traditional anti-DH regents such as calcium phosphate minerals fail in long-term occlusion of dentin tubules, resulting in recurrent attacks of DH.

Background: Dentin hypersensitivity (DH) is a common condition caused by exposed dentinal tubules, often requiring treatment with desensitizing agents. This in vitro study conducted at Narayana Dental College and Hospital (Nellore, AP, IND) between January 2022 and March 2022, aimed to evaluate the effectiveness of two desensitizing agents, SDI Riva Star (SDI Ltd., Bayswater, VIC, AUS) and Gluma Desensitizer (Kulzer, Hanau, DEU) in occluding dentinal tubules and their long-term durability following simulated brushing.

Molar-incisor hypomineralization (MIH) is an enamel defect affecting molars and incisors, often leading to hypersensitivity, enamel breakdown, and increased caries risk. Non-invasive treatments, such as casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) and fluoride varnish, show potential in remineralizing affected enamel and reducing sensitivity, but their efficacy is still debated. This study systematically reviews and analyzes the effectiveness of CPP-ACP and other non-invasive agents in improving remineralization and reducing hypersensitivity in MIH-affected teeth.
