Influence of azathioprine on healing of exposed dogs' dental pulp capped with three different materials.

Background: Azathioprine is one of the earliest immunosuppressants prescribed for several autoimmune diseases. Yet there is a lack of research on the impact of azathioprine on pulp healing following the pulp capping procedure.

Aim: This study aimed to investigate the effect of azathioprine on the healing ability of mechanically exposed dogs' dental pulps following direct pulp capping with mineral trioxide aggregate (MTA), bio-aggregates (BA), and Calcium hydroxide (Ca(OH)).

The impact of membrane perforation and L-PRF for vertical ridge augmentation with a xenogeneic block graft: an experimental study in a canine model.

Objectives: This study evaluated clinically and histologically the efficacy of modified perforated collagen membrane (PCM) and/or leukocyte- and platelet-rich fibrin (L-PRF) in combination with xenogeneic block bone graft in the vertical alveolar ridge augmentation.

Materials And Methods: Six adult mongrel dogs were enrolled in this randomized blinded study. After defect preparation, xenogeneic screw-fixed block graft was covered by an occlusive collagen membrane in group 1 that represented the control group (Block + CM).

The influence of self-inflating soft tissue expander on the outcomes of horizontal alveolar ridge augmentation: A randomized controlled clinical and histological study.

Objective: The present study was conducted to evaluate the effect of soft tissue augmentation using a self-inflating soft tissue expander when performed before horizontal alveolar ridge augmentation on the outcomes of the bone augmentation procedure. The primary outcome is the bucco-palatal radiographical changes in alveolar ridge width, while the secondary outcome is the quality of the augmented bone assessed histomorphometrically.

Materials And Methods: Sixteen patients underwent horizontal alveolar ridge augmentation using autogenous bone.

Influence of insulin on the healing of exposed dental pulp after pulp capping: An experimental study in a dog model.

Background: This study investigates the influence of insulin on pulp tissue healing after pulp capping in diabetic dogs.

Methods: Diabetes mellitus was induced in four dogs, and their blood glucose levels were adjusted by insulin to normoglycemic level in two dogs (normoglycemic group) and to hyperglycemic level in two dogs (hyperglycemic group). Class V buccal cavities were performed in 15 teeth in each diabetic dog and two normal dogs (control group).

Image cytometric analysis of p53 and mdm-2 expression in primary and recurrent mucoepidermoid carcinoma of parotid gland: immunohistochemical study.

Aims And Objectives: This study aims to analyze immunocytochemically p53 aberrant expression and mdm-2 expression in primary and recurrent mucoepidermoid carcinoma (MEC) of parotid gland and to ascertain if expression of these markers correlates with tumor behavior, clinical outcome, histological grade and local recurrence.

Methods: 20 cases histologically diagnosed as primary MEC with different grades were included in the study. Out of 20 cases, 7 were classified as grade I, 8 as grade II and 5 as grade III.

Immunohistochemical localization of mdm-2, p27Kip1 and bcl-2 in Warthin's tumor of the parotid gland.

Background: Warthin's tumor is a benign monomorphic adenoma with unclear origin that almost occur exclusively in the parotid gland. Etiology of Warthin's tumor as well as its malignant potential are still unclear. Therefore immunohistochemical assessment of Warthin's tumor may be useful to detect its origin or its malignant transformation potential.
