Some authors have been proposing the use of cavity disinfectants in order to reduce, or even eliminate, the effect of the microorganisms present in a dental cavity before a restoration is placed. The aim of this study was to evaluate the effect of different cavity disinfectants on bond strength and clinical success of composite and glass ionomer restorations on primary teeth. The research was conducted using Cochrane Library, PubMed/MEDLINE, SCOPUS, and Web of Science for articles published up to February 2021. The search was performed according to the PICO strategy. The evaluation of the methodological quality of each in vitro study was assessed using the CONSORT checklist for reporting in vitro studies on dental materials. Sixteen in vitro studies and one in situ study fulfilled the inclusion criteria and were analyzed. Chlorhexidine was the most studied cavity disinfectant, and its use does not compromise dentin bonding. Sodium hypochlorite is a promising alternative, but more research on its use is required to clearly state that it can safely be used as a cavity disinfectant for primary teeth. Although other disinfectants were studied, there is a low-level evidence attesting their effects on adhesion, therefore their use should be avoided.

“…In our present study, the melting of the dentin was insignificant, however, we found a slight fusion of the ends of collagen fibers. That process caused a partial blockage of dentin canals that can disturb the adhesion of filling materials or interrupt the formation of new clinical attachment after the periodontal recession coverage [52,53]. In order to solve this problem as well as open dentinal tubules as well as to increase its adhesion, the application of sodium subchloride was recommended by many authors [53][54][55].…”

Furthermore, any residues left in the cavity will result in inefficient adhesion [29] of gingival tissue to the tooth's surface.…”

Background: Recently, the defects of the tooth surface in the cervical region are often restored using composite filling materials. It should meet the needs of the patients regarding esthetics and material stability. The aim of the study was to analyze the tooth root surface at the cervical region after the removal of the composite filling material by means of the Erbium-doped Yttrium Aluminium Garnet (Er: YAG) laser or drill using the scanning electron microscopy (SEM) and fluorescence microscopy. Materials and Methods: For the purposes of this study, 14 premolar teeth (n = 14) were removed due to orthodontic reasons. The rectangular shape cavities with 3 mm in width and 1.5 mm in height were prepared with a 0.8 mm bur on high-speed contra-angle in the tooth surface just below cemento-enamel junction (CEJ) and filled with the composite material. The composite material was removed with the Er: YAG laser at a power of 3.4 W, energy 170 mJ, frequency 20 Hz, pulse duration 300 μs, tip diameter 0.8 mm, air/fluid cooling 3 mL/s, and time of irradiation: 6 sec, at a distance from teeth of 2 mm (G1 group, n = 7) or a high-speed contra-angle bur (G2 group, n = 7). After the removal of composite material, the surfaces of teeth were examined using the scanning electron microscopy (SEM) and fluorescence microscopy. Results: The Er: YAG irradiation allowed to remove completely the composite material from the tooth cavity. The study confirmed, that the ends of collagen fibers were only partially denatured after the Er: YAG laser application. Conclusion: It has been proved that using the Er: YAG laser is an effective and safe method of composite removal for the dentin surface.

Objective: The aim of this study is to compare the shear bond strength of composite resin bonded to enamel of primary teeth after etching using Erbium chromium –YSGG laser and conventional phosphoric acid. Study design:Experimental in vitro study. Materials and Methods: A total of thirty extracted or exfoliated primary teeth were divided into three groups according to the type of etching techniques. Group I Er,Cr:YSGG Laser etching with power set at 1W, Group II Er,Cr:YSGG laser with power set at 1.5W and group III acid etching using phosphoric acid. Evaluation: The 30 specimens were assigned for shear bond strength (SBS) evaluation test using a universal testing machine. Mode of failure was evaluated using stereomicroscope and only six specimens were evaluated qualitatively to asses enamel surface topography using scanning electron microscopy. Results: Shear bond strength of acid etching group showed the highest followed by 1.5W laser-etching group, while 1W laser etching group demonstrated the least mean shear bond strength. The acid etched enamel was statistically significantly higher (P < <0.0001) than that other groups. Conclusions: The mean SBS of composite with acid etching is significantly higher in comparison to Er, Cr: YSGG (operated at 1W & 1.5W for 10 s) laser‑etched enamel.
