“…In previous clinical studies, several investigators have also used the VAS, because it is easily understood by patients, it is sensitive in discriminating among the effects of various types of treatments, and it thus is suitable for evaluating the pain response seen in studies of DH. 8,9,15 The results of the present clinical trial demonstrate that both the Nd:YAG and 685-nm diode lasers were effective in desensitizing hypersensitive teeth. The results particularly illustrate their effectiveness following cold air jet stimulation.…”

“…The use of lasers for the treatment of sensitive teeth may be divided into two groups: lasers with moderate power outputs, one of which is the Nd:YAG laser, and low-level lasers, one of which is the 685-nm diode laser. Both the Nd:YAG laser [8][9][10][11][12][13][14] and the 685-nm diode laser [15][16][17] have been tested for the treatment of DH by many investigators. Many of them, in spite of the wide variety of methods and types of lasers used, have proven to be successful.…”

“…[18][19][20][21] Previous results of treatment of DH with the diode laser have revealed that the laser's interaction with the dental pulp induces a photobiomodulating effect that increases cellular metabolic activity of odontoblasts, obliterates the dentinal tubules, and intensifies tertiary dentin production. 15,17 Because of the great variety of methods and types of lasers used, it is impossible to propose a definitive means of laser treatment of DH. Although lasers have often been suggested for this indication, prior to this study there have been no published data available comparing the clinical effectiveness of the Nd:YAG and the 685-nm diode laser for the treatment of DH.…”

Objectives: The aim of this study was to evaluate the effectiveness of two types of lasers, the Nd:YAG laser and the 685-nm diode laser, as dentin desensitizers as well as both the immediate and late therapeutic effects on teeth with gingival recession. Materials and Methods: The study was conducted on 56 teeth in 14 patients with Miller's class 1 and 2 gingival recession with clinically elicitable dentin hypersensitivity (DH). The patients were divided into two groups: a Nd:YAG-laser-treated group and a 685-nm diode laser-treated group. DH was assessed by means of an air stimulus, and a visual analog scale (VAS) was used to measure DH. The selected teeth in the two groups received laser therapy for three sessions. Teeth subjected to Nd:YAG-laser treatment were irradiated at 1 W and 10 Hz for 60 sec at 1064 nm, and those receiving 685-nm diode laser treatment were irradiated at 25 mW and 9 Hz for 100 sec. Results: Significant reductions in DH occurred at all time points measured during the three treatment sessions in both treatment groups. Comparing the means of the responses in the three treatment sessions for the two groups revealed that the Nd:YAG laser group had a higher degree of desensitization compared to the other group ( p < 0.01). The immediate and late therapeutic effects of the Nd:YAG laser were more evident than those of the 685-nm diode laser. Conclusions: Both of these lasers can be used to reduce DH without adverse effects. Desensitization of teeth with gingival recession with the Nd:YAG laser was more effective than with the diode laser. The Nd:YAG laser appears to be a promising new tool for successfully reducing DH.

“…Under normal conditions, dentin is covered by enamel or cement and does not suffer direct stimulation. However, the exposure of dentin tubules due to enamel loss by abrasion, erosion, abfraction or root surface exposure caused by gingival recession, periodontal treatment or a combination of both (2) may produce strong dentin sensitivity (3).…”

Dentin hypersensitivity after treatment with desensitizing agents: a randomized, double-blind, split-mouth clinical trial

The aim of this study was to evaluate the efficacy of two desensitizing agents in the reduction of dentin hypersensitivity in a randomized, double-blind, split-mouth clinical trial. Seventy-seven teeth from 13 patients that presented some degree of sensitivity to probing and/ or air stimulation were treated with one of the following desensitizing agents: Oxa-Gel (G1), Sensi Kill (G2) and placebo gel (G3 -control). According to paired t-test, all treatments, even the placebo gel, were capable of reducing sensitivity scores for both stimuli.Analysis of data by ANOVA and Tukey's test (α=0.05) showed that the sensitivity scores were significantly lower only for Sensi Kill in comparison to the other products (Oxa-Gel and placebo), when air stimulus was applied. It may be concluded that treatment with Sensi Kill presented a slightly better performance in reducing dentin hypersensitivity when compared to the other desensitizing agent.

“…[9] When comparing the efficacy of the two lasers (660 nm wavelength red, and 830 nm wavelength infrared), it was found that amongst the two, 660 nm red diode laser was more effective for dentine hypersensitivity and a higher level of reduction in sensitivity was observed at the 15 and 30 min postirradiation examinations. [10] Aranha et al also showed gradual reduction in dentine hypersensitivity using low-intensity laser (660 nm/3.8 J/cm²/15 mW). [8] After surgical removal of third molars LLLT has been shown to modulate the inflammatory process, by reducing pain and swelling and promoting the repair of damaged tissues without any harmful effects.…”

Lasers have gained an upper hand in almost every field of dentistry. Utilization of lowlevel laser therapy (LLLT) which uses a power of <500 mW have matured over time. Its advantages surpass its pitfalls and hardly have any contraindications. Low lasers interact photo-chemically leading to a change in the biochemical and molecular processes that normally occur in tissues such as healing or repair without the thermal effects, a process called bio-stimulation. It has been implied that low power lasers affects cellular metabolic processes and promotes beneficial biological effects such as analgesic, anti-inflammatory, and healing. Research suggests an analgesic effect, through the central release of serotonin and acetylcholine, and peripheral release of histamine and prostaglandins, with the use of LLLT. LLLT improve endorphin release and thereby impede nociceptive signals and control pain mediators. This article aims to review the interesting clinical applications of LLLT in different orofacial pain conditions in details so that we can help patients to live a pain-free life.
