Context:
Dentin desensitizers are used for in-office treatment of dentinal hypersensitivity. They block the open tubules and bring about a reduction in hypersensitivity.
Aim:
The aim was to evaluate and compare the clinical effectiveness of a dentin desensitizer, a combination of a dentin desensitizer + adhesive and one-bottle self-etching adhesive for in-office treatment of dentin hypersensitivity.
Settings And Design:
Institutional, prospective double-blind parallel clinical design.
Subjects And Methods:
A total of 54 teeth in 20 patients were randomly allocated to one of the three study groups, with 18 teeth in each group as follows: Group A-Gluma Desensitizer (GD), Group B-Gluma Comfort Bond + Desensitizer (GCBD), Group C-Single Bond Universal (SBU). The patients' dentinal hypersensitivity scores for tactile (hand-held scratch device), thermal (cold), and evaporative (dental unit air syringe) stimuli were recorded on a visual analog scale. The parameters were recorded at baseline, immediately after application of the agent, 3- and 6-week posttreatment.
Statistical Analysis Used:
The data were analyzed with Friedman's test, Wilcoxon signed ranks test, Kruskal-Wallis test, and Mann-Whitney-U-test (P < 0.05).
Results:
All three groups showed a significant reduction in dentinal hypersensitivity (P < 0.05) compared to baseline at all time intervals. Statistically, significant differences were noted between GD and SBU; between GCBD and SBU in all testing parameters. Between GD and GCBD no significant difference was noted.
Conclusions:
GD and GCBD showed a greater reduction in dentin hypersensitivity than SBU.

Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...

Local anesthetics are amphiphilic molecules consisting of a hydrophobic aromatic part linked to a hydrophilic group by an ester or amide linkage. They are weak bases and are usually available as salts, which increases their solubility and stability. Once administered, LAs exist in the body either...
