Introduction: Pathogens, such as cytomegalovirus, hepatitis B virus, hepatitis C virus, herpes simplex virus types 1 and 2, and human immunodeficiency virus are transmitted, threatening the health of dental laboratory workers, especially as a result of saliva and blood contact of patients. To prevent cross-infection, impression materials should be disinfected at the end of the impression process in the mouth. Aim: To study the effect of application time of sodium hypochlorite and quaternary ammonium-based disinfectant solution on the surface roughness of an elastomeric impression material. Materials and Methods: In this in-vitro study done during March 2020, 10 disc-shaped samples were used in each group, with a total of 110 samples obtained from a light body elastomeric impression material with dimensions of 15×3 mm. The samples were kept in a sodium hypochlorite solution (Wizard; Rehber Kimya, Istanbul, Turkey) at concentrations of 1% and 5% for 1, 5, 10, and 30 minutes and in a quaternary ammonium-based disinfectant (Zeta 7 Solution, Zhermack SpA, Italy) for 10 and 30 minutes. Surface roughness measurements were taken with a profilometer device. The data obtained were statistically analysed by Kolmogorov-Smirnov test and Wilcoxon signed rank test for dependent/paired groups for the continuous data. The significance level was set to α=0.05. Results: A statistically significant difference was found between the control group and the 1% sodium hypochlorite (30 min p-value 0.037), and 5% sodium hypochlorite (30 min p-value 0.017). The statistical evaluation of the surface roughness of the samples with different concentrations of sodium hypochlorite and the same times was done and found statistically significant at 30 mins, p-value 0.021. Conclusion: The prolonged application of the sodium hypochlorite disinfectant at 1% and 5% concentrations caused a significant increase in the light body elastomeric impression material’s surface roughness

Acrylic resin dentures are a type of denture that is often used. At present the use of disinfectants to clean dentures from microorganisms, such as sodium hypochlorite and green betle leaves. Sodium hypochlorite contains chlorine, and green betle leaf extract contains tannins that containable to provide color changes in artificial teeth. The purpose of this study was to study the change in color on the hot polymerization acrylic plate after soaking with sodium hypochlorite solution and green betle leaf extract (Piper betle Linn). This study was a pre-post test control group design, the sample was heat-cured resin acrylic base plate and divided into 3 treatment groups: a group immersed in sodium hypochlorite, extract of green betel leaf and control group with aquades. The discoloration measurement was using Spectrophotometer. The sample was immersed for 15 days. Data were analyzed by paired T-test, followed by One way Anova and LSD. The results showed that there were significant color changes in the 2 treatment groups, while the control group was not significant. The mean of discoloration after immersion with Sodium Hypochlorite was 0.668 + 0.018, green betle leaf extract 30% was 0.625 + 0.024, and aquades was 0.534 + 0.0224. Color changes on heat-cured resin acrylic base plate occur by the presence of chlorine in sodium hypochlorite and tannin contained in the green betel leaf extract. This research concluded that immersion of heat-cured resin acrylic plate in sodium hypochlorite solution and 30% betle leaf extract may cause discoloration.

The effectiveness of sodium dodecyl sulphate (SDS), sodium hypochlorite solution and levulinic acid in reducing the survival of heat adapted and chlorine adapted <em>Listeria monocytogenes</em> ATCC 7644 was evaluated. The results against heat adapted <em>L. monocytognes</em> revealed that sodium hypochlorite solution was the least effective, achieving log reduction of 2.75, 2.94 and 3.97 log CFU/mL for 1, 3 and 5 minutes, respectively. SDS was able to achieve 8 log reduction for both heat adapted and chlorine adapted bacteria. When used against chlorine adapted <em>L. monocytogenes</em> sodium hypochlorite solution achieved log reduction of 2.76, 2.93 and 3.65 log CFU/mL for 1, 3 and 5 minutes, respectively. Using levulinic acid on heat adapted bacteria achieved log reduction of 3.07, 2.78 and 4.97 log CFU/mL for 1, 3, 5 minutes, respectively. On chlorine adapted bacteria levulinic acid achieved log reduction of 2.77, 3.07 and 5.21 log CFU/mL for 1, 3 and 5 minutes, respectively. Using a mixture of 0.05% SDS and 0.5% levulinic acid on heat adapted bacteria achieved log reduction of 3.13, 3.32 and 4.79 log CFU/mL for 1, 3 and 5 minutes while on chlorine adapted bacteria it achieved 3.20, 3.33 and 5.66 log CFU/mL, respectively. Increasing contact time also increased log reduction for both test pathogens. A storage period of up to 72 hours resulted in progressive log reduction for both test pathogens. Results also revealed that there was a significant difference (P ≤ 0.05) between contact times, storage times and sanitizers. Findings from this study can be used to select suitable sanitizers and contact times for heat adapted and chlorine adapted <em>L. monocytogenes</em> in the fresh produce industry.

The effect of ‘Vitosept’ drug, based on sodium hypochlorite solution with high purity, obtained in a specially developed membraneless flow electrolyzer, on the embryotoxic and teratogenic properties in rats was investigated. To determine the embryotoxic effect of ‘Vitosept’ on the development of white rats offspring of the 1st generation, control and three experimental groups (G1, G2, G3) were formed from pregnant females. The females of the control group with a blunt probe were injected daily for 30 days with 5 ml of isotonic sodium chloride solution, and experimental ones with 5 ml of ‘Vitosept’ drug with different concentration of high purity sodium hypochlorite: Group I (G1) — 50 mg/l; Group II (G2) — 100 mg/l; Group III (G3) — 500 mg/l. The animals were observed. During the observation the condition and behavior of the females, the dynamics of body weight change, duration of pregnancy, and the course of birth were monitored. The results of the experiment were recorded after the slaughter of pregnant females (20th day of pregnancy) and in the postnatal period of development of the offspring. Studies have shown that the use of different concentrations of the drug ‘Vitosept’ in rats for 30 days before and during pregnancy has no embryotoxic and teratogenic effects. According to the indicators of the total, pre- and postimplantation lethality of embryos, there were no reliable changes in the structure and morphometry of internal organs and tissues in 20-day-old fetuses, and their development corresponded to the terms of pregnancy. There was no significant difference between the fertility of female rats in the test and control groups. The average number of fetuses per female was within 9 animals. The rats obtained from the females of the experimental groups were viable and did not lag behind in growth and development compared with the control animals, which generally characterizes the studied drug ‘Vitosept’ as non-toxic, lacking embryotoxic and teratogenic action

DIAGNOdent is a laser fluorescence device used for dental caries diagnosis in occlusal and smooth surfaces. Despite the promising preliminary results, the molecules involved in the increase of fluorescence in carious lesions remain unclear. The aim of this study was to compare the laser fluorescence readings before and after changes in the organic material of occlusal carious lesions in primary teeth. Twenty-four primary molars stored in saline solution with at least one site with occlusal caries were divided into two groups. The control group had 17 sites with caries and the experimental one had 16 sites. The carious lesions were measured with laser fluorescence. The experimental samples were then removed from the storage solution and immersed in a 2% sodium hypochlorite solution for 24 hours. After washing with water, the teeth were measured again with the laser fluorescence device. The teeth of the control group were submitted to the same procedures, but saline solution was used instead of the sodium hypochlorite solution. A statistically significant reduction in the mean of the readings after immersion in the two tested solutions compared with the initial readings was observed in both groups, but the decrease was statistically higher in the experimental group (p < 0.0001). In this study, the data indicate that changes in the fluorescence of carious lesions measured by the laser fluorescence are mainly due to the organic content alterations rather than to the mineral loss.

OBJECTIVES: The aim of this study was to determine the effect of Er:YAG laser irradiation used to clean dentinal walls on the apical sealing of root canals filled with different types of sealers. Background Data: Laser application to the dentinal walls removed debris, rendering the root canals free of smear layers and leaving the dentinal canaliculi open. METHODS: Sixty-four maxillary canines obtained from laboratory files were instrumented with K-files (Dentsply, Maillefer, Ballaigues, Switzerland) using the crown-down technique, and irrigated with a 0.5% sodium hypochlorite solution. The specimens were divided into two groups of 32 teeth each. In group I, the teeth were instrumented and irrigated with sodium hypochlorite solution, and divided into four subgroups to be sealed with the different materials (Endofill, N-Rickert, Sealapex and Sealer 26). In group II, the root canals were subjected to Er:YAG laser irradiation (200 mJ, 7 Hz and 60 J total energy), followed by root canal sealing as in group I. RESULTS: The data showed lower levels of apical microleakage in the teeth filled with N-Rickert, Sealapex and Sealer 26 cements than in those sealed with Endofill (p < 0.01). No significant difference in microleakage was observed between teeth irrigated only with 0.5% sodium hypochlorite and those submitted to Er:YAG laser application (p > 0.05). CONCLUSIONS: The Er:YAG laser irradiation applied to the root canal walls was not able to prevent apical microleakage.
