In Vitro Comparison of Surface Characteristics and Bacterial Adhesion in Composite Resin-Based Materials for Additive, Subtractive, and Conventional Manufacturing.

Purpose: This study aims to compare the surface roughness (SR), contact angle (CA), surface free energy (SFE), and bacterial adhesion of resin-based materials used in additive, subtractive, and conventional manufacturing techniques.

Materials And Methods: This study involved four groups of 23 specimens: Indirect conventional resin composite (ICRC), subtractively manufactured resin composite (SMRC), additively manufactured resin composite (AMRC), and soda-lime-silica glass (SLSG). One specimen per group was analyzed by Energy Dispersive X-ray Spectroscopy (EDS) before polishing.

Surface characteristics and wettability of novel gingival col designed 3-D printed dental sectional matrices.

Objective: 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, Shenzhen, China). The physical textures, thicknesses, water contact angles were compared to conventional stainless steel (SS) matrix.

Caries-related and Preventive Dental Care of 5-, 12-, and 15-year-old Syrians in Bursa, Türkiye.

Objectives: Türkiye has implemented an open-door policy for Syrians since the beginning of the Syrian crisis in 2011 and has been providing medical and dental services for Syrian asylum seekers. Bursa, being the 5th largest city in the Western region of the Turkish Republic, hosts 1,83,355 registered Syrians. The present study was designed to analyze the caries-related dental services and preventive applications among 5-, 12-, and 15-year-old Syrian patients admitted to a state-affiliated dental hospital in Bursa, Türkiye.

COVID-19 Reflections on Restorative Treatments of Permanent First Molars.

Background 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, Türkiye.

Quantification of Surface Relation Between Experimental Polylactic Acid Dental Matrix and Type II Glass Ionomers Using Peel Adhesion Test and Fourier Transform Infrared Spectroscopy.

Aim: 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.

Diagnostic Performance of ICDAS II, FluoreCam and Ultrasound for Flat Surface Caries with Different Depths.

The use of ultrasound for the diagnosis of natural caries lesions with different depths on flat surfaces of permanent molar teeth was studied. A total of 200 freshly extracted permanent molar teeth with natural caries lesions were included. After evaluation with International Caries and Detection Assessment System II (ICDAS II), mineral loss and lesions in the teeth were detected with a fluorescence device, FluoreCam and lesion depths were measured using ultrasound.
