İmplant üstü sabit restorasyonlarda kron sökümünün implant osseointegrasyonuna etkisinin incelenmesi: Tavşan modeli

Turan Emre KUZU | Hasan Murat AYDOĞDU

Amaç: Diş eksikliklerinin giderilmesinde implant uygulamalarının popülaritesi gün geçtikçe artmaktadır. Osseointegrasyonu tamamlamış implantların üzerine kuron-köprü protezleri yapılarak hastaların tedavileri tamamlanır. Ancak kimi zaman protetik ve cerrahi komplikasyonlar kimi zamansa implant çevresi dokuların enfeksiyonları sebebiyle simante edilen protezler tekrar çıkarılmak zorunda kalır ve bu geri çıkarma işlemi sırasında uygulanan kuvvetlerin implant osseointegrasyonuna ve kemik implant arayüzüne etkisi incelenmemiştir. Gereç ve Yöntem: Bu çalışmada implant üstü sabit protezlere uygulana ...Daha fazlası

Evaluation of early bone recovery in grafted jaw with anterior iliac bone: a retrospective study

Kübra ÖZTÜRK

ims Atrophic jaws make implant planning difficult due to the lack of bone, and this situation directs the surgeon to advanced surgical methods. Today, autogenous grafts are still the gold standard. The aim of this study was to evaluate the bone stability of horizontal bone grafts taken from the iliac crest. Materials and metods Twenty patients receiving horizontal bone grafts were included in this retrospective cohort study. All patients were treated with bone harvested from the anterior iliac crest. The measurements were made by means of a caliper. Screw heads reference point taken. Resorptio ...Daha fazlası

Evaluation of methods for determining working length in root canal treatment for primary molars: An ın-vivo study

Ebru DELİKAN

BACKGROUND/AIMS The aim of this study was to evaluate the effectiveness of tactile sensation, digital periapical radiography, and two varieties of electronic apex locators (EALs) as methods of determining working length in root canal treatment for primary molars. MATERIAL and METHODS In this study, 30 infected mandibular primary second molar teeth in 12 children aged 5-8 years were analyzed. The working length was determined for each tooth using the tactile sensation, digital radiography, the ProPex PixiVR, and IpexVR apex locators separately. RESULTS The mean root canal measurements taken usi ...Daha fazlası

Approaches of general and specialist dentists to deep caries management: a cross-sectional study from turkey

Ebru DELİKAN

Objective:To determine the differences in treatment strategies and material preferences for deep dentine carious lesions (DDCLs) management among general and specialist dentists. Methods:Dentists working in universities, oral and dental health centers, or private practice were administered a 14-item web-based questionnaire regarding demographic and occupational characteristics, approaches to DDLCs, pulp capping methods, and preferences for restorative materials. The data were examined using descriptive statistical analysis and Pearson’s chi-square tests.

The effects of different antioxidant agents on the microtensile bond strength of composite resin to bleached enamel

Özcan KARATAŞ

The objective of this in vitro study is to examine the effect of antioxidants on the bonding strength of composite resin to bleached enamel. One hundred twenty non decay teeth were used in this study. Specimens were cut from the enamel cement junction. Then the specimens were randomly assigned into two groups-office bleaching and home bleaching. Bleaching antioxidants were applied to the first 12 subgroups. The specimens in the remaining 12 groups were kept in artificial saliva for 14 days and antioxidants were applied. Composite resin restoration was applied to all specimens. A cutting device ...Daha fazlası

Evaluation of color stabilization of peri-implant mucosa in different restorative material, abutment and tissue thickness combinations: an in vitro study

Turan Emre KUZU | Kübra ÖZTÜRK | Damla Güneş ÜNLÜ

Aim The aim of this in vitro study is to determine the level of color change of the peri-implant mucosa in several combinations of parameters, including different experimentally-created peri-implant tissue thicknesses, and different prosthetic crown and abutment materials, by spectrophotometric measurements. Materials and methods In this in vitro study, a sheep’s head was used because it resembles human mucosa in terms of color and texture. Different experimentally-created peri-implant tissue thicknesses were determined, i.e. 1, 1.5, 2 and 3 mm, and to provide these thicknesses 0.5, 1 and 2 mm ...Daha fazlası

Does childhood chemotherapy affect mandibular bone structues in a life time?

Hatice Cansu KIŞ | Ebru DELİKAN

Background: Chemotherapy, one of the most important treatment modalities for treating childhood cancers, is a major cause of bone loss in patients and survivors. Objectives: This study aimed to evaluate mandibular bone structures in childhood cancer survivors (CCSs) by means of fractal dimension (FD) analysis and the Klemetti index (KI), and to compare them with regard to the control group. Material and methods: In this retrospective study, the panoramic radiographs of 49 CCSs were included as the study group and the panoramic radiographs of 49 cancer-free volunteers were included as the contr ...Daha fazlası

The effect of prophylaxis paste and air‑powder polishing on color stability and surface roughness of different composite resins

Özcan KARATAŞ | Turan Emre KUZU

Aim: This study examined the impact of periodontal prophylaxis paste and air‑powder treatment on nano‑ and microhybrid composite resin surface roughness and color change. Materials and Methods: Thirty specimens were prepared from a nanohybrid and a microhybrid composite resin. The specimens were distinct into three subgroups, and the first color measurements were done. Then, a periodontal prophylaxis paste was applied to one of the subgroups prepared from each composite, and air‑powder polishing was applied to the second subgroups, and specimens in the third subgroup were kept in distilled wat ...Daha fazlası

A novel homozygous frameshift mutation in the PLCB4 gene associated with auriculocondylar syndrome 2 and accompanied by mild intellectual disability

Kübra ÖZTÜRK

Auriculocondylar syndrome is a rare autosomal dominant or recessive disorder characterized by question-mark ears, a small mandibular condyle, and micrognathia. From a molecular perspective, auriculocondylar syndrome arises due to mutations in the PLCB4, GNAI3, and EDN1 genes that play roles in the endothelin signaling pathway. Here, we report a patient with findings of auriculocondylar syndrome and an additional mild intellectual disability. The patient’s whole exome sequencing analyses revealed a novel homozygous frameshift mutation in the PLCB4 gene related to auriculocondylar syndrome Type ...Daha fazlası
