“…In vitro study the mean SEM was significant among Control group compared to Group A (Fluoride Varnish) and Group B (Dentin Bonding Agent) which was significant than Group C (Laser). A study conducted by Corneli R et al 18 showed similar result as in this study in which laser showed 100% occluded tubules followed by fluoride varnish while the control group showed completely open tubules. In a study comparing laser and fluoride, Tosun S et al 19 found that laser application improved tubular occlusion capacity.…”

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.

“…These clinical studies showed that the sensitivity score decreased rapidly and lasted for a long period following the regular use of SnF 2containing dentifrice [26,27]. NaF is present in desensitizing varnishes at concentrations as high as 2-5% [28][29][30]. If dentifrices contain a minimal amount of NaF (0.15-0.32%), the tubule occlusion effect is insufficient and it may be improved when combined with different agents such as potassium salts [31].…”

Purpose: This study examined the occlusion effect of a dentifrice containing stannous fluoride (SnF 2 ) and sodium fluoride (NaF) on periodontally involved teeth in comparison with healthy teeth using scanning electron microscopy (SEM) in comparison with a dentifrice containing NaF alone. Methods: Sixty dentine samples obtained from single-rooted premolars, 15 of them extracted for orthodontic reasons (Group H) and 15 because of periodontal destruction (Group P), were included in the study. Each group of specimens was further divided into subgroups: HC and PC (control), H1 and P1 (treated with SnF 2 and NaF), and H2 and P2 (treated with NaF). The samples were brushed twice a day for 7 days, kept in artificial saliva, and examined by SEM. The diameters of open tubules and the numbers of tubules were assessed at ×2,000 magnification. Results: The H and P groups showed similar diameters of open tubules.The numbers of open tubules in Groups H1, P1, H2, and P2 were significantly lower than in Groups HC and PC (P < 0.001), and consistent with the percentages of occluded tubules. Group P1 had the highest percentage of occluded tubules. Conclusions: Although both dentifrices were found to successfully occlude dentinal tubules, the dentifrice containing SnF 2 and NaF provided the highest degree of occlusion in periodontally involved teeth.

Context: Over the years, numerous treatment modalities have been researched for the management of dentinal hypersensitivity. A recent remineralizing agent containing a phase of amorphous calcium phosphate combined with fluoride has shown the ability to rapidly convert into biomimetic hydroxyapatite. This potential can be utilized in occluding the dentinal tubules for the treatment of hypersensitivity. Aims: The present study aims to compare the effectiveness of biomimetic hydroxyapatite-based tooth mousse and casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) tooth mousse as desensitizing agents on dentinal tubule occlusion. Materials and Methods: The in vitro study design involved 30 prepared dentin specimens that were divided into three groups: Group A: negative control, Group B: CPP-ACP tooth mousse (GC tooth mousse™), and Group C: fluoride-doped amorphous calcium phosphate (F-ACP) tooth mousse (Curasept Biosmalto Denti Sensibili Tooth Mousse). The specimens were observed under a scanning electron microscope (SEM) and an attached energy-dispersive X-ray (EDX) spectroscopy apparatus after 1 week. Statistical Analysis: The data were analyzed using Kruskal–Wallis test and post hoc Mann–Whitney test for intragroup and intergroup analysis, respectively. Results: The SEM analysis of the F-ACP group showed statistically greater percentage of tubule occlusion (40.21%) compared to the CPP-ACP group (38.15%). EDX analysis of both F-ACP and CPP-ACP groups revealed calcium, phosphorus, carbon, oxygen, and silica with an additional fluoride element in the F-ACP group. Conclusions: In the present study, both remineralizing agents were able to occlude the dentinal tubules. Among the two, the F-ACP tooth mousse showed greater tubule occlusion, and therefore, appears promising as an upcoming remineralizing agent in the management of dentinal hypersensitivity.
