The evaluation of the mandibular bone structure changes related to lactation with fractal analysis

Hatice Cansu KIŞ

Objectives Lactation-induced bone loss of lumbar spine, hip, femur and distal radius are well documented in the literature. The aim of this article is to investigate whether lactation afects the trabecular and cortical bone structure of human mandible. Methods 120 dental panoramic radiographs (DPR) of the lactating women who were breastfeeding for 3–6 months (study group) and 120 DPRs of the nulliparous women (control group) were evaluated. Regions of interest (ROI) were chosen from the geometric center of ramus, the geometric center of angulus and the cortical bone. ROIs were examined with fr ...Daha fazlası

Monomer release from nanohybrid composite after bleaching

Özcan KARATAŞ

The evaluation of the effect of bleaching on monomer release from two composite resins was performed by bleaching two nanohybrid composite resins Filtek Z550 and Tetric N-Ceram using two bleaching products Whiteness HP Maxx and Vivastyle. In total, 20 samples were made from each composite resin from which four groups were fabricated (two for each bleaching product). The samples were stored in a 75% ethanol solution, and the solutions were renewed after 1, 7, and 28 days. The monomer release was analyzed using high performance liquid chromatography. The data were analyzed using repeated measure ...Daha fazlası

An evaluation of surface roughness after staining of different composite resins using atomic force microscopy and a profilometer

Özcan KARATAŞ

Aim: The aim of this study was to compare the surface roughness of different composite resins using atomic force microscope (AFM) and a profilometer after storage in different solutions. Materials and methods: Eight different composite resins were used in this study. Twenty specimens of each composite resin material were prepared using a 2-mm thick and 8-mm diameter stainless steel mold. After the composites had been placed in the mold, they were polymerized with a LED curing unit. The surfaces of all specimens were polished using aluminum oxide discs, and the specimens were then divided into ...Daha fazlası

Evaluation of the peri-implant bone trabecular microstructure changes in short implants with fractal analysis

Hatice Cansu KIŞ

Backgrounds: This study aimed to evaluate the microstructural changes in the peri-implant bone in patients with short implants in terms of implant survival status by using fractal analysis measurements. Results: Dental panoramic radiographs (DPRs) of 67 patients were examined and included in this study. Fractal analysis and measurement of the crown-implant ratio were performed with ImageJ. The fractal analysis measurement was performed on the DPRs obtained at preoperative (FD0) and in the follow-up periods (after 2 ± 2 weeks (FD1), 2 months ± 2 weeks (FD2), 6 months ± 2 weeks (FD3), and 12 mon ...Daha fazlası

The effect of two different irrigation needles on post-operative pain after pulpectomy in primary molar teeth: A randomized clinical study

Ebru DELİKAN

Background: Post-operative pain (PP) following pulpectomy is of concern for endodontic patients and dentists. Aim: This study evaluated the intensity of PP following pulpectomy in primary maxillary molars, using two irrigation needles. Design: One hundred patients in ages ranging from 6-9 years requiring pulpectomy for asymptomatic primary teeth with non-vital pulp were included in the study. The participants were randomly assigned to two groups of 50 patients each, according to the type of irrigation needle used, that is, a conventional open-ended needle and a double side-vented needle. The t ...Daha fazlası

The effect of periodontal disease treatment in patients with continuous ambulatory peritoneal dialysis

Cem Abdülkadir GÜRGAN

Purpose Chronic inflammation is an obvious risk factor of atherosclerotic diseases, and the presence of periodontal disease is one of the important sources of chronic inflammation in patients with chronic kidney disease (CKD) and diabetes mellitus (DM). Thus, we aimed to investigate the effects of non-surgical periodontal therapy of the patients undergoing CAPD due to diabetic nephropathy, diabetic patients without CKD, and healthy controls on inflammation exponents. Methods Thirty-two CAPD patients due to diabetic nephropathy (group III), 31 diabetic patients without nephropathy (group II), a ...Daha fazlası
