“…The agents work by occluding the tubule, which restricts fluid passage, or by altering the neurological response to pain stimuli. 5 Fluoride varnish seem to work by decreasing dentinal permeability by formation of calcium fluoride crystals inside the tubules of the dentinal tubules. Saliva dissolves these crystals to some extent.…”

One of the most commonly faced clinical problems is dentinal hypersensitivity (DH).It's a "enigma" that's "often met yet seldom comprehended." It is defined as a sensation of discomfort caused by exposed dentine in response to heat, chemical, tactile, or osmotic stimulation. It appears to be a common ailment, with estimates ranging from 4% to 74 percent of the population.The study aimed in evaluating the efficacy of sodium fluoride varnish, dentine bonding agent and diode laser in treating dentine hypersensitivity in vitro and in vivo.The research was split into two parts: in vitro and in vivo. In the in vitro study, 40 anterior teeth were extracted and separated into four groups: control, group A (fluoride varnish), group B (dentine bonding agent), and group C (laser), all of which were studied under a scanning electron microscope. For the in vivo part 30 patients aged 20-50 years with the chief complaint of sensitivity to hot and cold were selected from the outpatient department (OPD) of Seema Dental college and Hospital. The patients were divided into 3 groups, group A(fluoride varnish), group B (dentine bonding agent) group C (laser).At the end of 3 months, there was a statistically significant difference seen in mean VAS and VRS scores between Group A, Group B, and Group C; additionally, the mean of dentinal tubules in the SEM study (In vitro) was seen to be significantly higher in the Control group compared to Group A and Group B, and significantly higher than Group C.According to the findings of this study, all three treatment methods, sodium fluoride varnish, dentine bonding agent and laser are efficient in reducing dentine hypersensitivity in both in vivo and vitro studies, with laser showing better outcomes.

The aim of this study is to evaluate intratubular crystal formation from the experimental material consisting of dicalcium silicate (C2S) and tricalcium silicate (C3S) with nano-scaled particle size. A total of twenty-four specimens were made by isolating 8 mm of the cervical part centered at the cementoenamel junction of extracted premolars. Twelve specimens were not treated and considered as control. The experimental material was applied to the other twelve specimens by brushing for 10,000 strokes. Each group was randomly divided into four subgroups according to the period of immersion in phosphate buffer saline (PBS) for 1, 30, 60, and 90 days each. The specimens were sectioned longitudinally and examined with scanning electron microscopy and energy dispersion X-ray spectroscopy. The intratubular crystal were formed in PBS and densely filled the dentinal tubules over time. The crystal formation occurred at a depth of more than 50 μm from the dentin surface. The Ca/P ratio of formed intratubular crystals was 1.68 after 3 months. The experimental material consisting of C2S and C3S with a nanoscale particle size can form hydroxyapatite-like crystals in dentinal tubules in PBS, and there is a possibility of reducing dentin hypersensitivity by blocking the dentinal fluid flow.

Objectives This study aimed to evaluate intratubular crystal formation from the experimental material consisting of dicalcium silicate and tricalcium silicate (C2S/C3S). Materials and Methods A total of twenty-four specimens were made by isolating 8 mm of the cervical part centered at the cementoenamel junction of extracted premolars. Twelve samples of the exposed upper dentin surface were treated with ethylenediaminetetraacetic acid followed by sodium hypochlorite to simulate sensitive dentin. The other twelve specimens were not treated and considered as controls. The experimental material consisting of C2S/C3S with a nano-scaled particle size was applied to the other twelve specimens by brushing for 10,000 strokes. Each group was randomly divided into four subgroups according to the period of immersion in phosphate-buffered saline (PBS) for 1, 30, 60, and 90 days. The specimens were sectioned longitudinally and examined via scanning electron microscopy and energy dispersion X-ray spectroscopy. Results The intratubular crystal was formed in PBS and densely filled the dentinal tubules over time. Crystal formation occurred at a depth of more than 50 µm from the dentin surface. The Ca/P ratio of formed intratubular crystals was 1.68 after three months. Conclusion Intratubular crystals were formed and grown in the dentin from nano-sized C2S/C3S particles under PBS, and the Ca/P ratio of the crystals was similar to that of hydroxyapatite. Clinical Relevance C2S/C3S with a nanoscale particle size can form intratubular crystals in PBS, and there is a possibility of reducing dentin hypersensitivity by blocking the dentinal fluid flow.
