International Arab Journal of Dentistry

ABSTRACT

Objectives: The aim of this study was to investigate the anatomy of the maxillary and mandibular premolars among a sample of the Lebanese population and to explore their incidence by sex and the symmetry between the left and right sides. Materials and Methods: This retrospective analysis of 250 cone-beam computed tomography (CBCT) scans consisted of 960 maxillary and 972 mandibular premolars. Roots, canals, and morphology types were recorded. Vertucci’s classification was used to categorize the canal morphologies. Fisher’s exact and chi-square tests (P≤.05) were applied.

Results: The majority of maxillary first premolars had two roots (85.3%) with two …

Effect Of Chlorhexidine On Nanoleakage And Bond Durability Of Two Adhesives To Dentin: An In Vitro Study, Rowayda Anwar Eltarawy, Essam Naguib, Ahmed Z. Elhoshy, Sara H. Younis

Future Dental Journal

Abstract

Aim: This study aimed to investigate the effect of chlorhexidine (CHX) on nanoleakage (NL) and dentin bond durability of two adhesives after water storage.

Materials and Methods: Thirty-six extracted molars were divided into three groups and their buccal surfaces were reduced to expose flat dentin surfaces. In group 1 Single Bond Universal Adhesive (SBU) was used, in group 2 Peak universal Bond (PUB) was applied while in group 3 Chlorhexidine Gluconate Disinfecting Solution followed by Single Bond Universal Adhesive (CHX+SBU) was used. Application of resin composite restorations was performed in all three groups. For each bonding procedure, …

Future Dental Journal

Background: The aim of the present study was to measure the clinical and pain score in these patients and to measure the level of IL-17 in saliva of patients having different forms of Oral lichen planus lesions (OLP).

Subjects and methods: According to sample size calculation, the present study was done on a total of 40 subjects divided into 3 groups Group (I) Twenty patients having erosive/atrophic OLP. Group (II) Ten patients having reticular OLP and Group (III) Ten healthy control patients. Salivary samples were collected from the subjects of the three groups to evaluate the levels of IL-17 using …

Accuracy Of Diffusion Weighted Magnetic Resonance Imaging In Differentiation Between Malignant And Non-Malignant Maxillofacial Lesions, Rana M. Ashraf, Mostafa S. Ashmawy, Mena E. Y. Ekladious, Gihan A. Omar, Mona Abu El Fotouh

Future Dental Journal

Objectives: to evaluate the signal characteristics of Diffusion Weighted Magnetic Resonance Imaging (DWMRI) of maxillofacial intraosseous lesions and their corresponding apparent diffusion coefficient (ADC) values and assess their ability to differentiate between malignant and non-malignant lesions.

Methods: This study included 17 patients (10 males and 7 females) selected from the outpatients’ clinic of Oral Surgery Department, Faculty of Dentistry, Ain-shams University. They were examined by MRI machine; Philips 1.5 Tesla Achieva, Netherlands using DWMRI, T1 and T2 sequences and ADC values were measured.

Results: There was a statistically significant difference between T1 signal distributions among patients with …

Comparative Evaluation For The Effect Of Green Tea, Aloe Vera And Chlorhexidine On Dentin Erosion, Nourhan Moustafa Moustafa, Rasha Afifi, Maha Ahmed Niazy, Essam Naguib

Future Dental Journal

ABSTRACT:

Purpose: This study aimed to compare the anti-collagenolytic effect of Green tea, Aloe vera and chlorhexidine on artificial erosion in human dentin using microhardness test and environmental scanning electron microscope (ESEM). Materials and Methods: For this study, 60 extracted sound human maxillary premolars were subjected to artificial erosion and randomly divided into three equal groups (20 premolars each) according to immersion in the tested anti-collagenolytic agents; group (A₁) Green tea, (A₂) Aloe vera and group (A₃) Chlorhexidine (CHX). The microhardness analysis and (ESEM) photomicrographs were taken for the surface of dentin specimens three …

Fluoride Release Of Conventional Glass Ionomer Modified With Flax Fibers And Ethanolic Extract Of Propolis, Bassma Reda Abdelhafeez, Maha Ahmed Niazy, Essam Abdel Hafez Naguib, Sara Hany Younis

Future Dental Journal

Purpose: This study aimed to evaluate the fluoride release of conventional glass ionomer (GI) modified with flax fibers and/or ethanolic extract of propolis (EEP) with and without thermo-cycling. Materials and Methods: 80 total discs of GI were prepared, 20 discs per group: Group (GI) conventional glass ionomer (control), Group (F) glass ionomer incorporated with 5% flax fibers, Group (P) glass ionomer incorporated with 1% ethanolic extract of propolis (EEP), Group (FP) glass ionomer incorporated with 5% flax fibers and 1% ethanolic extract of propolis (EEP). Fluoride release testing was performed after the first day and after 7 days. Results: …
