Effect of a novel bioceramic root canal sealer on the angiogenesis-enhancing potential of assorted human odontogenic stem cells compared with principal tricalcium silicate-based cements.

Objective: This study evaluated the angiogenesis-enhancing potential of a tricalcium silicate-based mineral trioxide aggregate (ProRoot MTA), Biodentine, and a novel bioceramic root canal sealer (Well-Root ST) in human dental pulp stem cells (hDPSCs), human periodontal ligament stem cells (hPLSCs), and human tooth germ stem cells (hTGSCs).

Paraneoplastic diseases and collagen vascular diseases may also occur with many different acral skin findings.

Number and size of acquired melanocytic nevi and affecting risk factors in cases admitted to the dermatology clinic.

Introduction: The size and number of acquired melanocytic nevi (AMN) and presence of dysplastic nevi are the leading risk factors that should be recognized in the development of malignant melanoma.

Aim: To evaluate AMN and risk factors in the development of AMN in all age groups admitted to a dermatology outpatient clinic.

Material And Methods: Four hundred and twelve patients who were admitted to the dermatology outpatient clinic for any dermatological symptom and who accepted to participate in the study were randomly included in the study.

Investigation of Enthesopathy with Ultrasonography and Comparison with Skin Findings in Asymptomatic Psoriatic Patients.

Background: Joint involvement associated with psoriasis is referred to as psoriatic arthritis. A late diagnosis of psoriatic arthritis may cause a variety of morbidities; therefore, an early diagnosis and treatment of psoriatic arthritis are required. Asymptomatic psoriatic arthritis has been found in 8-70% of patients with psoriasis using imaging techniques.
