Publication Surface characteristics and wettability of novel gingival col designed 3-d printed dental sectional matrices(Walter De Gruyter Gmbh, 2023-07-28) Çelik, Halil; Çelik, Zeynep Ceren; ÇELİK, ZEYNEP CEREN; Elbek Çubukçu, Çiğdem; ELBEK ÇUBUKÇU, ÇİĞDEM; Bursa Uludağ Üniversitesi/Diş Hekimliği Fakültesi/Periondontoloji Anabilim Dalı.; 0000-0002-6900-2632Objective: The physical properties and wettability of 3-D printed Polyethylene terephthalate - glycol (PET-G) and Poly(lactic) acid (PLA) dental sectional matrices were investigated.Methods: Experimental matrices was designed in a rectangular shape one-side depression corresponds to gingival col and without sharp edges and printed on FDM machine Ender Pro 3 (Creality((R)), Shenzhen, China). The physical textures, thicknesses, water contact angles were compared to conventional stainless steel (SS) matrix.Results: PETG and PLA sample matrices were clinically single-side smooth compared to SS matrix. PETG specimens had uniformly 0.055 mm whereas PLAs were non-uniformly similar to 0.065-0.075 mm in thickness. The mean +/- standard deviation (SS) of contact angle for SS was 78.29 +/- 0.18, for PETG was 72.09 +/- 0.94, for PLA was 73.03 +/- 1.17.Conclusion: PETG and PLA dental matrices might have desirable properties: being hydrophobic, non-charged, easy to manufacture and mimicking the gingival col depression in the dental interproximal contact area.Publication Knowledge and attitudes of pregnant women with and without children about fluoride and herbal toothpastes(Marmara Üniversitesi, 2023-03-01) Çelik, Zeynep Ceren; Çubukcu, Çiğdem Elbek; Çelik, Halil; Ata, Gül Dinç; ÇELİK, ZEYNEP CEREN; ELBEK ÇUBUKÇU, ÇİĞDEM; DİNÇ ATA, GÜL; Bursa Uludağ Üniversitesi/Diş Hekimliği Fakültesi/Restoratif Diş Hekimliği Anabilim Dalı.; Bursa Uludağ Üniversitesi/Diş Hekimliği Fakültesi/Pedodonti Anabilim Dalı.; 0000-0002-6900-2632; AAW-9821-2021; AAH-2726-2021; AAH-1497-2021Objective: 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.Publication Covid-19 reflections on restorative treatments of permanent first molars(Springernature, 2023-03-20) Çelik, Zeynep Ceren; ELBEK ÇUBUKÇU, ÇİĞDEM; ÇELİK, ZEYNEP CEREN; Çubukçu, Çigdem Elbek; Bursa Uludağ Üniversitesi/Diş Hekimliği Fakültesi.; 0000-0002-6900-2632; AAW-9821-2021Background and Aim: It is important to provide appropriate dental care for newly erupted permanent first molars (PFMs) since they are susceptible to caries. As the coronavirus disease 2019 (COVID-19) pandemic has led to significant changes in the way dental services are provided to patients, the purpose of this study is to examine the procedure records assigned to PFMs of 6-15 year-olds during the pandemic and analyze the restorative material preferences of the residents of public dental hospitals. Materials and Methods: Procedure records of patients aged between 6-15 years were extracted from the Public Oral and Dental Health Center, Bursa, Turkiye. All teeth groups except PFMs were excluded, while extracted, survived (restorative/endodontic/prosthetic procedures), and prevented (fissure sealant application) PFMs were analyzed retrospectively. Furthermore, restorative material preferences were analyzed by arch location, cavity surfaces, and dentition types. Results: Strong positive correlation was seen between age and PFM extraction (r=0.973; p<0.001) and age and PFM restorative treatments (r= 0.966; p<0.001); a negative correlation was detected between age and fissure sealants (r=-0.984; p<0,001) performed on PFMs of 8-15-year-olds. Amalgam was most often preferred as the restorative material (p<0.05). Conclusion: The distribution of treatments and dental restorations can vary based on many factors, and the pandemic conditions may have changed treatment preferences to favor preventive dentistry. The excess of multi-surface restorations may be related to the delay of treatment applications during COVID-19.Publication Quantification of surface relation between experimental polylactic acid dental matrix and type ii glass ionomers using peel adhesion test and fourier transform infrared spectroscopy(Springernature, 2023-02-28) Çelik, Zeynep Ceren; ÇELİK, ZEYNEP CEREN; Çubukcu, Çiğdem Elbek; ELBEK ÇUBUKÇU, ÇİĞDEM; Bursa Uludağ Üniversitesi/Diş Hekimliği Fakültesi.; 0000-0002-6900-2632; AAW-9821-2021Aim: Type II glass ionomer cement (GIC) is a posterior restorative material that is generally not recommended for interaction with stainless steel due to chemical ion exchange. The purpose of this study is to quantify the surface relation of experimental three-dimensional (3D)-printed polylactic acid (PLA) and type II GIC using the peel adhesion test and Fourier transform infrared spectroscopy (FT-IR).Materials and methods: Experimental PLA dental matrix specimens were 3D printed in the form of an open circumferential dental matrix (75x6x0.0055 mm) using a fused deposition modeling (FDM) machine. The peel resistance test (ASTM D1876) was applied to determine the relative peel resistance of the adhesive bonds between the PLA dental matrix, traditional circumferential stainless steel (SS) matrix, and GIC. The PLA bands were characterized using an FT-IR spectrophotometer (Spectrum 100, PerkinElmer Inc., Waltham, MA, USA) for the simultaneous determination of the chemical relationships of the surfaces before and after the GIC was set in a simulated class II cavity model.Results: The mean peel strengths (P/b) +/- standard deviations of the PLA and SS dental matrix bands were 0.0017 +/- 0.0003 N/mm and 0.3122 +/- 0.0042 N/mm, respectively. The-C H stretching was observed at 3383 cm(-1) after adhesion, which corresponded to vibrational movements on the surface.Conclusion: It required similar to 184 times less force to separate the GIC from the PLA surface compared to the traditional SS matrix. Additionally, there was no evidence of a new chemical bond or strong chemical interaction occurring between the GIC and the experimental PLA dental matrix.
