Desensitizing effects of an Er:YAG laser on hypersensitive dentine

AIM: The aim of the present study was to evaluate and compare the desensitizing effects of an Er:YAG laser (KEY II(R), KaVo, Germany) and Dentin Protector (Vivadent, Germany) on cervically exposed hypersensitive dentine. METHOD: A group of 30 patients showing a total of 104 contralateral pairs of hypersensitive and caries-free teeth was selected and randomly allocated in a split-mouth design to either (1) Er:YAG laser (80 mJ/pulse, 3 Hz), or (2) the application of Dentin Protector (polyurethane-isocyanate 22.5%; methylenechloride 77.5%) whereat one pair served as an untreated control in each patient. The degree of sensitivity to a thermal stimulus was determined qualitatively with an evaporative stimulus defined as a 3-s air blast at a distance of 2 mm from each site to be tested. A qualitative registration of the degree of discomfort was determined according to an arbitrary pain scale in 4 degrees. Recordings were assessed before treatment, immediately after, 1 week, 2 and 6 months after treatment by 1 blinded examiner. RESULTS: Both treatment forms resulted in significant improvements of discomfort immediately after and 1 week post treatment. After 2 months, the discomfort in the Dentin Protector(R) group increased up to 65% of the baseline score and even up to 90% after 6 months, whereas the effect of the laser remained at the same level that was achieved immediately after treatment. The differences immediately after, 1 week, 2 and 6 months post treatment between both groups were statistically high significant (p< or =0.001; respectively). Compared to the untreated control group, both treatment forms resulted in a significant reduction of discomfort at each follow-up examination. CONCLUSION: It was concluded that desensitizing of hypersensitive dentine with an Er:YAG laser is effective and the maintenance of the positive result was more prolonged than with Dentin Protector.

Comparative Evaluation of Nd:YAG Laser and Fluoride Varnish for the Treatment of Dentinal Hypersensitivity

IntroductionVarious methods and materials are used in the treatment of dentin hypersensitivity. The aim of this randomized prospective controlled clinical trial was to evaluate and compare the desensitizing effects of the neodymium-doped yttrium aluminium garnet (Nd:YAG) laser and fluoride varnish by considering the degree of pre- and posttreatment pain, discomfort, and functional complications.MethodsTwenty patients with clinically diagnosed cervical dentin hypersensitive teeth were included and randomly allocated to either the application of fluoride varnish (group fluoride) or Nd:YAG laser (100 mJ, 20 Hz; group Nd:YAG). The assessment of pain and discomfort was performed by a visual analog scale after an air blast at baseline, immediately after treatment, and at patient visits on weeks 1, 2, 3, and 4.ResultsLaser treatment resulted in significant improvements of discomfort immediately after treatment and after 1 week. At the 2-, 3-, and 4-week examination, the discomfort in group fluoride decreased up to nearly 75% to 85% of baseline scores, whereas the effect of the laser stayed nearly unchanged. The visual analog scale scores for pain at 4 weeks examination were significantly lower in the fluoride group compared with those in the laser group (p < 0.05).ConclusionsNd:YAG laser is a suitable tool for the immediately successful reduction of dentinal hypersensitivity and has better patient satisfaction and shorter treatment time.     

Comparative study in desensitizing efficacy using the GaAlAs laser and dentin bonding agent

OBJECTIVE: To compare the clinical efficacy of the GaAlAs laser and dentin bonding agent in treating dentin hypersensitivity. METHODS: One hundred and forty teeth from 70 patients diagnosed with dentin hypersensitivity, were divided into two groups: In group I, teeth were irradiated with 30 mW GaAlAs laser for 1 min and in group II, teeth were applied with dentin bonding agent. Sensitivity was assessed by tactile and thermal tests, measured with the criteria proposed by Uchida at baseline and after treatment; immediately, at 15 and at 30 days. RESULTS: The reduction of dentin hypersensitivity was observed in both treatments using the GaAlAs laser and dentin bonding agent. However, a greater reduction was observed over time up to day 15 and no significant change was observed between days 15 and 30. Statistically significant differences in the level of dentin hypersensitivity between bonding agent and the GaAlAs laser were found at each observation period (p < 0.05). CONCLUSION: The GaAlAs laser had less desensitizing efficacy compared with dentin bonding agent. However, the desensitizing effect of the GaAlAs laser still could be considered an effective therapy for treating dentin hypersensitivity.     

The clinical effect of amorphous calcium phosphate (ACP) on root surface hypersensitivity

Dentin hypersensitivity is a transient condition that often resolves with the natural sclerotic obturation of dentin tubules. A method of rapidly forming calcium phosphate compounds within these tubules can mimic sclerosis and lead to rapid reduction in hypersensitivity. Amorphous calcium phosphates (ACP) can be formed in situ by the sequential application of calcium and phosphate solutions. In this clinical study, 30 patients with reported dentin hypersensitivity were randomly assigned to parallel treatment or placebo groups. In the experimental treatment group, ACP was formed by topical application of a 1.5 mol/L aqueous solution of CaCl2 followed by topical application of 1.0 mol/L aqueous K3PO4. The placebo group was treated with a topical application of 1.0 mol/L aqueous solution of KCl followed by topical application of distilled water. Treatments were repeated at the 7-day and 28-day recall appointments. Response to air and tactile stimuli were measured immediately before treatment using a visual analog scale initially on day 1, then on days 7, 28 and 180. The results showed that both the experimental and placebo treatments resulted in a reduction in hypersensitivity at 180 days. However, the ACP treatment group showed a much more rapid reduction in hypersensitivity over time. The change in sensitivity was much more apparent using the air stimulus than the tactile stimulus. These results show that topical placement of ACP can rapidly reduce dentin hypersensitivity.
