“…After 2 weeks, only stable blocked tubules were observed in the toothpaste group and Er,Cr:YSGG laser group, and finally, after 1 month, only in Er,Cr:YSGG laser group, the dentinal tubules were completely blocked or at least narrowed. Therefore, a stable treatment of dentine hypersensitivity, during a month, is obtained with Er,Cr:YSGG laser, which confirms our results that the effect of sensitivity reducing by using laser continues for up to 1 week and 1 month without significant change, and then gradually decreased its effectiveness [42].…”

Dentinal hypersensitivity (DH) is a common clinical condition usually associated with exposed dentinal surfaces. The aim of this study was to study the effect of sodium fluoride varnish, Gluma, and Er,Cr:YSGG laser, in the dentin hypersensitivity treatment. One hundred sixty-five teeth with dentin hypersensitivity in 55 patients were involved in this study. Teeth are divided into five groups based on the received treatment (n = 33): G group: Gluma; F group: sodium fluoride varnish (5%); L group: Er,Cr:YSGG laser (wavelength 2780 nm, frequency 20 Hz, power 0.25 W, energy density 44.3 J/cm 2 , and pulse width of 150 µs at distance of 1 mm for 30 s) which was followed by Er,Cr:YSGG laser; GL group: Gluma + laser; VL group: both sodium fluoride varnish and Gluma, which are common treatments for hypersensitivity, were selected as control groups. The treatment was performed in one session, and the sensitivity to air spray conditioning was recorded after the treatment, at 15 min, 1 week, 1 month, and 6 months as the VAS. Statistical analysis was performed using SPSS Ver. 21 software. One-way ANOVA was used to compare the VAS between all treatment groups at each time-point. One-way repeated measurements ANOVA (RM-ANOVA) and two-way-repeated measurements ANOVA (RM-ANOVA) were used to compare the hypersensitivity of each group and sensitivity of all treatment groups, respectively. Tukey post hoc test was used to compare the groups pairwise. The hypersensitivity between different groups at before and 15 min after the treatment was not significantly different (P = 0.063). The hypersensitivity of all studied groups was decreased after the treatment. The Er,Cr:YSGG laser, alone or in combination with Gluma, in 1 week, 1 month, and 6 month follow-ups, had significantly reduced the hypersensitivity instead of sodium fluoride varnish. All treatments significantly reduced the dentin hypersensitivity up to 6 months. Er,Cr:YSGG laser alone or in combination with Gluma was more effective than sodium fluoride varnish; however, it was not significantly different from other treatments. In a 6-month follow-up of dentine hypersensitivity treatment, Gluma had a significantly higher effect than sodium fluoride. Trial registration: IRCT20190422043343N1. Registered 19 July 2019.

“…assessed the outcome of Er, Cr: YSGG laser on the occlusion of dentinal tubules with other agents (such as desensitizing toothpaste, desensitizing varnish, and desensitizing paste) used on exposed dentin surface at varying intervals of time with the help of SEM and they observed that the Er, Cr: YSGG laser (Waterlase) caused the opening of dentinal tubules to various degrees over different periods. [ 20 ] Gholami et al . evaluated the outcome of Er, Cr: YSGG laser, Nd: YAG, and 810 nm diode lasers on the occlusion of dentinal tubules and they concluded that the lasers have the capability to melt peritubular dentin, can partially or completely cause occlusion of dentinal tubules, and therefore, reduces hypersensitivity.…”

Context: Regeneration of periodontal tissues depend on the adhesion and development of fibrin clots to the root surface. Demineralization of the root surface ensures removal of smear layer uncovering dentin tubules and collagen matrix. Root conditioning agents were introduced to remove the smear layer and enhance the adhesion of blood components. Aims: The aim of the study was to determine the effect of erbium, chromium-doped yttrium, scandium, gallium and garnet (Er, Cr: YSGG) laser on smear layer removal (SLR) and fibrin network formation when compared to tetracycline, and ethylene-diamine-tetra-acetic acid (EDTA) for periodontal regeneration. Settings and Design: The study was conducted at Amrita school of dentistry and the study design involves in vitro comparative study. Subjects and Methods: Forty dentinal sections were prepared from freshly extracted teeth that were periodontally affected. The samples were divided into four groups: Scaling and root planing (SRP), tetracycline, EDTA, and Er, Cr: YSGG laser. The samples were assessed using a scanning electron microscope and photomicrographs were taken and analyzed for removal of smear layer, blood component adhesion (BCA), and fibrin network formation. Statistical Analysis Used: Analysis of variance test and Kruskal–Wallis test with P < 0.05 considered to be statistically significant. Results: There was a significant difference between Er, Cr: YSGG laser, tetracycline hydrochloride, and EDTA categories when compared with SRP categories. There was no significant difference between Er, Cr: YSGG laser, tetracycline, and EDTA according to SLR scoring and BCA scoring. Conclusions: It can be concluded that Er, Cr: YSGG laser-treated samples presented complete elimination of smear layer, formation of fibrin network, and BCA along with desensitizing effect for a better reduction in dentin hypersensitivity.
