“…Irradiated deciduous surfaces showed an increase in roughness when energy density did augment similar to our previous report (Teutle‐Coyotecatl et al, ). This phenomena may be associated to the appearance of accentuated morphologic changes, such as the detachment of material and more extended and numerous craters observed by Zamudio‐Ortega et al () at higher energies, which are produced by thermal degeneration (Hossain et al, ).…”

“…The untreated enamel samples showed homogeneity roughness values similar to a previous study carried out on permanent teeth (Teutle‐Coyotecatl et al, ), which demonstrated that there is no significant difference among roughness values when comparing natural deciduous versus permanent enamel.…”

“…For each sample and for each group, average values were calculated. Finally, the following roughness parameters were assessed: Ra (the average distance from the profile to the mean line over the length of assessment) and Rz (the peak‐to‐valley values of five equal measures within the profile) under ISO 4287‐1997 (Teutle‐Coyotecatl et al, ).…”

“…Two reference strains were tested separately on tested surfaces; S. mutans ATCC 25175 and S. sanguinis ATCC 10556. Lyophilized bacteria stocks (American Type Culture Collection, Rockville, MD) were grown on HK enriched agar plates at 37° C under anaerobic conditions (80% N 2 , 10% CO 2 , and 10% H 2 ) to obtain pure cultures (Teutle‐Coyotecatl et al, ).…”

Effect of Er:YAG laser irradiation on deciduous enamel roughness and bacterial adhesion: An in vitro study

et al. 2019

Laser irradiation has been proposed as a preventive method against dental caries since it is capable to inhibit enamel demineralization by reducing carbonate and modifying organic matter, yet it can produce significant morphological changes. The purpose of this study was to evaluate the influence of Er:YAG laser irradiation on superficial roughness of deciduous dental enamel and bacterial adhesion. Fifty‐four samples of deciduous enamel were divided into three groups (n = 18 each). G1_control (nonirradiated); G2_100 (7.5 J/cm2) and G3_100 (12.7 J/cm2) were irradiated with Er:YAG laser at 7.5 and 12.7 J/cm2, respectively, under water irrigation. Surface roughness was measured before and after irradiation using a profilometer. Afterwards, six samples per group were used to measure bacterial growth by XTT cell viability assay. Adhered bacteria were observed using confocal laser scanning microscopy (CLSM) and a scanning electron microscopy (SEM). Paired t‐, one‐way analysis of variance (ANOVA), Kruskal‐Wallis and pairwise Mann–Whitney U tests were performed to analyze statistical differences (p < .05). Before treatment, samples showed homogenous surface roughness, and after Er:YAG laser irradiation, the surfaces showed a significant increase in roughness values (p < .05). G3_100 (12.7 J/cm2) showed the highest amount of Streptococcus mutans adhered (p < .05). The increase in the roughness of the tooth enamel surfaces was proportional to the energy density used; the increase in surface roughness caused by laser irradiation did not augment the adhesion of Streptococcus sanguinis; only the use of the energy density of 12.7 J/cm2 favored significantly the adhesion of S. mutans.

The purpose of this study is to compare the effect of a demineralization model on the microhardness, surface roughness, and topography of giomers.Seventy‐two discs of six different dental materials in three different presentations (pit and fissure sealant (PFS), flowable and restorative materials) were divided into six groups (n = 12 p/g). Three experimental groups (giomers) consisted of BeautiSealant, Beautifil Flow Plus, and Beautifil II, and three control groups (resin‐based materials) were formed using ClinproTM, FiltekTM Z350 XT Flow, and Filtek™ Bulk Fill materials. Vickers microhardness, surface roughness, and topographic analysis with atomic force microscopy were measured at the beginning (0) after four (1) and 7 days (2) of immersion in a demineralizing model. Statistical analysis was performed using One‐way and Repeated Measures ANOVA and Pearson's correlation coefficient (p ≤ .05). The microhardness values showed significant variations, except for the G_RM group. All the groups presented significant increases in roughness through the experiment stages, except for RB_PFS in the Ra parameter. The topographic analysis showed variations in the micromorphology, especially in the experimental group at the end of the demineralization model. Finally, there was no correlation between microhardness and surface roughness. The demineralization model decreased the microhardness, with the lowest reductions in the giomers groups. The effect of the demineralizing model on the surface roughness and topography showed an increase in specific patterns for the experimental and control groups. Therefore, their clinical use is recommended.Research Highlights The demineralization model decreased the microhardness property of the evaluated materials, with better performance for the giomer groups. The effect of the demineralizing model on surface roughness showed an increase with specific patterns for the experimental and control groups. Although the materials presented changes in their microhardness, roughness, and topography, their clinical use is recommended.
