    Objective: Objective: Pregnant women may be vulnerable to dental caries due to their inability to fully implement oral hygiene practices. Toothpastes are main component of oral hygiene and the most important tool for the primary prevention of caries. The study aimed to examine the knowledge and attitudes of pregnant women with children (PC) and without children (PNC) about fluoride and herbal toothpastes.Methods: A self-administered and validated 20-item questionnaire was completed by a total of 219 pregnant participants, 85 PC and 134 PNC. Statistical analyses were performed using the SciPy v1.2.3. program.Results: Most of the PC (57.65%; 69.41%) and PNC (72.39%; 47.76%) participants responded with "no idea" when asked about fluoride sources and the optimal amount of fluoride added to tap water by local health authorities (p= .006). The majority of the PC (62.4%) and the PNC (47.0%) had no preference for herbal toothpastes during pregnancy (p= .03). In addition, 86.6% of the PNC showed low knowledge about the nonfluoride content of herbal toothpastes (p= .023). While 51.5% of the PNC responded with "no idea" about a preference for herbal toothpastes for their children, 56.47% of the PC stated that they might not prefer using herbal toothpastes for their children's routine oral hygiene.Conclusion: The findings show that both PC and PNC participants had little knowledge of toothpastes and their contents. Considering that toothpastes are the most common self-applied oral hygiene tools, knowledge and awareness of fluoride and herbal toothpastes should be raised via antenatal programs.

    Effect of ozone on bond strength of different restorative materials to enamel and dentin
    (Taylor, 2022-08-25) Ata, Gül Dinç; Müjdeci, Arzu; DİNÇ ATA, GÜL; Bursa Uludağ Üniversitesi/Diş Hekimliği Fakültesi/Restoratif Diş Hekimliği Anabilim Dalı; 0000-0001-8272-5782; AAH-1497-2021
    The aim of this study is to examine the effects of ozone treatment applied at two different times, followed by the in vitro application of a reductant solution, on the shear bond strength of four different restorative materials to enamel and dentin. A total of 400 caries-free human molar teeth were randomly divided into enamel and dentin groups, and each was divided into five subgroups. The O20 group received 20-s ozone, O20 + R received 20-s ozone+reductant solution, O80 received 80-s ozone, O80 + R received 80-s ozone+reductant solution, and C was the control group. Each subgroup was then divided into four more subgroups based on restorative material (i.e., nanohybrid resin composite, silorane-based microhybrid resin composite, compomer, or conventional capsulated glass ionomer cement). After water storage for seven days, shear bond-strength data (MPa) were measured using a universal testing machine at a crosshead speed of 0.5 mm/min until fracture, and failure types were examined. The effects of ozone and ozone+reductant applications on enamel and dentin were examined via scanning electron microscopy (SEM). Bond strength data were statistically evaluated using a three-way analysis of variance and Tukey's honestly significant difference test (a= 0.05). The bond strength of the control group was like that of the O20 group (p > 0.05), but it was higher than all other groups regardless of the type of restorative material or tooth structure (p < 0.05). Adhesive-type failures were found in most groups. Via SEM examinations, it was observed that ozone applications did not change the enamel morphology, but they did cause narrowing of the dentinal tubule openings in O80 + R.
