“…Thus they concluded that Er:YAG laser can be an alternative method before sealant application. 28 Our findings contrast with those of Nahvi and colleagues. 29 They reported significant reduction in micro-leakage with the use of a pre-sealant bonding agent.…”

Background Considerable evidence shows that sealing dental pits and fissures contributes to caries prevention in children and adolescents. Various approaches are available for pit and fissure sealing. Sealants can be inserted with or without mechanical preparation; etching can be applied, with or without bonding. Lasers can be used as an alternative for mechanical preparation. In this study, we systematically evaluated the retention and micro-leakage of pit and fissure sealants, comparing mechanical preparation and Er:Yag laser enamel preparation. For each of these preparations we compared sealants without etching to those with etching, with and without bonding.Methods Sixty extracted sound third molars were classified into 6 groups: A. bur mechanical preparation and sealant application; B. bur mechanical preparation, etching and sealant; C. bur mechanical preparation, etching, bonding and sealant; D. laser mechanical preparation and sealant; E. laser mechanical preparation, etching and sealant application; F. laser mechanical preparation, etching, bonding and sealant. Pit and fissure sealing were evaluated by assessing the retention and micro-leakage of the sealant.Results All the groups showed dye micro-leakage beneath the sealants. Less micro-leakage was observed for the groups that used bur (groups A, B, C) than laser (groups D, E, F): 41 versus 44 specimens. The number of specimens without micro-leakage decreased as follows: group E (24), group A (18), groups B and F (17), group C (14) and group D (5). The difference in penetration between group D and the other groups was statistically significant, p<0.001, chi square.Conclusion Mechanical preparation is important and increases the retention of sealants, especially when using etching material; bonding can help the retention. We recommend preparing sealant with laser, without etching and bonding before its application.

“…The study by Dumurs et al [22] used Er: YAG laser at a wavelength of 2.94 μm, 2 W power, 120 mJ energy output and 10 Hz frequency. Mahtab et al [45] found no difference in the proportion of microleakage between conventional acid etching and Er: YAG laser surface pretreatment before sealant resin was applied to teeth with fluorosis, where the parameters were 30 mJ, 20 Hz, 6 W initially and 120 mJ, 10 Hz, and 1 W on the enamel margins. Unal et al [46] evaluated the Er:YAG laser as an alternative to acid etching for the application of fissure sealants in pediatric dentistry and found that the Er: YAG laser with 4 W power and 200 mJ energy output resulted in higher microtensile bond strength than the 2 W, 100 mJ Er: YAG laser in permanent teeth.…”

Background This systematic review aimed to assess the clinical effects of laser preparation compared to other types of chemical or mechanical preparation of tooth surfaces used in fissure sealant placement. Methods A systematic literature search was conducted up to January 2019, through Pubmed, Scopus, Medline/EMBASE via OVID and the Cochrane library. Only randomized clinical trials were included. Results Five studies were included in the systematic review and three were included in the meta-analysis. All the studies used acid-etching as a comparator to lasers. All the included studies were rated as having an overall high risk of bias introduced by performance bias. Three studies assessed the clinical effects of fissure sealants placed by acid or laser etching, one compared acid etching versus laser combined with acid etching and one investigated the influence of lasers on the objective and subjective parameters of stress during sealant application in children. The meta-analysis showed no significant difference between laser preparation and conventional acid-etching preparation at 3- ( P = 0.08), 6- ( P = 0.49), and 12-month ( P = 0.87) follow-ups. One study reported that laser preparation as an adjunct to acid-etching enhanced the retention rate. No significant difference in the incidence of caries was reported. And no significant differences were found in heart rates, oxygen saturation or degree of the patient dental anxiety between acid-etching and laser preparation. Conclusion The present limited evidence suggests that lasers could be an effective pretreatment method. The retention rate was similar to that of conventional acid etching. However, the included studies had an overall high risk of bias and more rigorously designed research is needed.

“…Some studies recommend preparing cavities with laser treatment to increase resin adhesion to the tooth structure (Yazici et al, 2013;Memarpour et al 2014), or even as an alternative to surface etching (Hossain et al, 2012;Walsh, 2003). However, the effectiveness of this method is controversial (Oznurhan and Olmez, 2013;Tarçin et al, 2009).…”

The aim of the study was to evaluate the adhesion of a self-adhering flowable composite resin to primary tooth enamel and dentin after silicon carbide paper (SiC) and laser pretreatment. Adhesive properties were evaluated as shear bond strength (SBS) and scanning electron microscopic (SEM) characteristics. A total 120 primary canine teeth were randomly divided into two groups to study enamel and dentin. Each group was divided into 6 subgroups (n = 10) according to type of surface preparation (SiC or Er:YAG laser) of enamel or dentin. Three methods were used to build cylinders of restoration on tooth surface: OptiBond All-In-One + Premise Flowable composite, OptiBond All-In-One + Vertise Flow and Vertise flow. After restoration, samples were tested for SBS and failure mode. Twenty eight samples were examined by SEM. The results of the study showed SBS of Vertise Flow was lower than others in enamel and dentin samples pretreated with SiC and in dentin samples pretreated with laser (P < 0.001). Compared to SiC pretreatment, laser pretreatment led to a significantly higher SBS with Vertise Flow on enamel (P < 0.001). Vertise Flow associated with the adhesive led to a higher SBS in enamel and dentin compared to Vertise Flow alone. Adhesive and mixed failure modes were observed more frequently in Vertise Flow groups. SEM images showed that Vertise Flow led to more irregularities on enamel and more open dentinal tubules after laser ablation compared SiC pretreatment.
