“…Certain crystals composed of calcium from the dentin tubules, and some ions (e.g., fluoride and phosphate), are precipitated into the dentin tubules. Numerous active principles of tubular occlusion have been described, including chemical: fluorides [ 2 ], oxalates [ 3 ], or arginine [ 4 ], and physical: adhesives [ 5 , 6 ] or laser therapies [ 7 ]. In addition, certain dental materials (resin composites, glass ionomer cements, and bonding agents) cover the root surface and seal the open dentin tubules.…”

This study aimed to use an in-air micro-particle-induced X-ray/gamma emission (in-air µPIXE/PIGE) system to evaluate tooth-bound fluoride (T-F) in dentin following the application of fluoride-containing tooth-coating materials. Three fluoride-containing coating materials (PRG Barrier Coat, Clinpro XT varnish, and Fuji IX EXTRA) and a control were applied to the root dentin surface of human molars (n = 6, total 48 samples). Samples were stored in a remineralizing solution (pH 7.0) for 7 or 28 days and then sectioned into two adjacent slices. One slice of each sample was immersed in 1M potassium hydroxide (KOH) solution for 24 h and rinsed with water for 5 min for the T-F analysis. The other slice did not undergo KOH treatment and was used to analyze the total fluoride content (W-F). The fluoride and calcium distributions were measured in all the slices using an in-air µPIXE/PIGE. Additionally, the amount of fluoride released from each material was measured. Clinpro XT varnish demonstrated the highest fluoride release among all the materials and tended to show high W-F and T-F and lower T-F/W-F ratios. Our study demonstrates that a high fluoride-releasing material shows high fluoride distribution into the tooth structure and low conversion from fluoride uptake by tooth-bound fluoride.

Objective This trial evaluated the influence of polishing on enamel color change after in-office bleaching treatment. In addition, it evaluated the influence of polishing on tooth morphology and sensitivity. Materials and methods Fifty volunteers were randomized into two groups (n = 25): In-office bleaching with 35% hydrogen peroxide gel for 45 min without polishing (GSEM) or with polishing (GP). The color analysis was performed four times, at baseline, and immediately after the 1st, 2nd, and 3rd session of bleaching with Easyshade spectrophotometer (Vita-Zahnfabrik), using the CIELAB (ΔE) and CIEDE2000 (ΔE00) formulas, and whiteness index (ΔWID). A qualitative analysis of enamel morphology was performed using replicas obtained with epoxy resin observed in a scanning electron microscope (277× and 554× magnification). The tooth sensitivity was assessed daily using the visual analog scale (α = 0.05). Results There was no statistically significant difference (p > 0.05) in tooth color change when comparing ΔE, ΔE00, and ΔWID between groups. The enamel surface showed greater areas of irregularities and depressions in the GP group than in the GSEM group. There was no difference in tooth sensitivity (p > 0.05) between groups. Conclusions Polishing after in-office tooth whitening does not change the tooth color and sensitivity and promotes greater changes in enamel surface morphology. Clinical relevance: Polishing immediately after tooth whitening causes greater changes in enamel surface morphology.

Dentin hypersensitivity (DH) is prevalent among the global population, affecting between 8% and 57%, with an average of 33.5%, thereby reducing the quality of life due to discomfort and pain. Despite DH being a widespread issue, there are no universally accepted guidelines for choosing reliable treatment methods. As the number of products designed to reduce dentin sensitivity increases, it becomes more challenging for dentists to make the informed choice. This literature review aims to explain the mechanisms of action and the sequence of use of contemporary dentin desensitization agents available on the market. Purpose. To provide the overview and discuss current principles and technical approaches to the treatment of DH in dental practice, with particular emphasis on hygiene products aimed at reducing nerve ending sensitivity and occluding dentin tubules. Materials and Methods. The literature search on DH treatment was conducted using PubMed and Google Scholar databases. Keywords used in the search included “dentin hypersensitivity”, “dentin hypersensitivity treatment” and “dentin hypersensitivity prevention”. The articles included in this review were published between 2019 and 2024, with full-text availability in English. Some references published earlier were also cited based on their relevance to DH treatment. Conclusions. There are various potential causes of DH and available treatment options. Each patient should be provided with an individualized plan, beginning with non-invasive treatment options. Therefore, communication between the doctor and the patient regarding rational hygiene practices, behavior modification, and the effectiveness of individual hygiene products is crucial for the successful treatment of this condition. Prospects for further research. The clinical significance of this review lies in the necessity of uncovering the dental and medical history of the patient, as well as identifying active etiological factors of DH, if possible, at the beginning of treatment. The results obtained will contribute to the correct choice of individual hygiene products and the provision of quality dental care to patients.
