“…(51) However, SBS results of the three groups are considered acceptable and capable of withstanding masticatory forces, as they all exceed the minimum SBS (5.9-7.8) MPa suggested by Reynolds. (52) Similar results were reported by Mézquita-Rodrigo et al, in 2017 (53) who found the highest SBS with conventional acid etching when compared to self-etching adhesive and laser. There was significant difference between conventional acid etching and Er: YAG laser.…”

Objectives:The aim of the present study was to compare the effect of enamel pre-treatment with: 37% phosphoric acid-etching or self-etching adhesive and Er:YAG Laser (2940nm) on shear bond strength, microleakage and penetration depth of a fluoride-releasing resin-based pit and fissure sealant applied to sound premolars.Methods: Seventy-two sound premolars were allocated randomly into 3 groups according to enamel pretreatment protocol. The experimental groups included: Group I: 37% phosphoric acidetching, Group II: self-etching adhesive, Group III: Er:YAG Laser treatment. Each group was divided into two subgroups (A: shear bond strength, B: microleakage and penetration depth). Shear bond strength test was performed using Universal testing machine. Microleakage and penetration depth were tested after thermocycling (500×, 5-55°C, dwell time: 30s) and dye penetration method. Samples were assessed under Stereo-microscope with a magnification of ×40. One-way ANOVA followed by Tukey's post hoc test was used to analyze data.Results: Shear bond strength and microleakage results showed that there was statistically significant difference among different groups while penetration depth results showed there was no statistically significant difference among all groups.Conclusions: Conventional acid etching was the best pretreatment method prior to resin-based fissure sealants in terms of bond strength and microleakage.

“…Numerous ex vivo dentistry studies are conducted to assess the physical, chemical and biological features of various materials in order to implement the results in dental practice. [1][2][3][4][5] In order to obtain reliable results in such research, the tested materials or tooth samples should be properly prepared and stored.…”

Laboratory research in dentistry and dental education use extracted human teeth as a model for simulation for ex vivo procedures. Human-borne tissues are the first choice of material for bond strength assessment. To obtain comparable results in dental material tests and to ensure microbiological safety, specimens must be stored under specific, uniform conditions. The aim of this paper was to present the contemporary view and recommendations on preserving extracted human teeth. The antimicrobial properties of the storage medium are a crucial aspect, as extracted teeth pose a risk of cross-infection. A classification of different methods (using solutions and otherwise) is presented and their sterilizing efficiency is compared based on the literature. The emphasis is put on the interaction between the storage conditions and the substrate. Tooth specimens should be biologically safe and have normal mechanical properties. The sterilizing process must be neutral for the enamel and dentin microstructure, because even a minor change can affect the adhesive bonding. Autoclave sterilization and storage in 10% formalin solution are widespread and reliable methods, although they do have their disadvantages. There is a need for further investigation in order to establish uniform recommendations on preparing and preserving extracted human teeth used for research purposes.
