Synergistic Potential Of Ivermectin And Doxorubicin In Oral Squamous Cell Carcinoma: An In Vitro Investigation, Dalia Ghalwash, Shereen Nader, Rana Tantawy

Dentistry

Background Doxorubicin (DOX) is widely used in cancer therapy, but its role in oral squamous cell carcinoma (OSCC)is limited by resistance and dose-related toxicities. Ivermectin (IVM), an antiparasitic agent with emerging anticancer properties, may enhance DOX efficacy. This study evaluated the effects of IVM alone and in combination with DOX on OSCC cell lines.

Methods In vitro assays, including MTT viability, apoptosis (Annexin V/PI), cell cycle analysis, RT-qPCR of apoptotic, proliferative, and inflammatory markers, and oxidative stress assays, were performed on HN9 and HEp-2 OSCC cell lines, with OEC as control.

Results IVM reduced cancer cell viability in a dose-dependent …

Effect Of Smoking And Finishing And Polishing Protocol On Color Stability And Surface Roughness Of Resin Composite, Fatma Makkeyah, Mohamed Samy Salama, Sara Adel Botros, Mohamed Shamel, Mahmoud Al Ankily

Dentistry

Purpose To investigate the influence of smoking and finishing and polishing protocol on color stability and surface roughness of resin composite. Materials and methods Seventy-two discs fabricated from supra-nanofilled composite were divided to 6 groups according to: Tobacco Product (Conventional Cigarette/CS and Heated Tobacco/HTP); and Finishing and Polishing Protocol (Control/C, Multi-step finishing system/FS, and Medium-grit abrasive bur + two-step polishing system/ PS). After finishing and polishing, specimens were exposed to a total of 600 cigarettes, divided into 20 each day, simulating 30 days of smoking. Color parameters were detected using a spectrophotometer. Surface roughness (Ra) was measured before and after …

Effect Of Resin Restorative Material Type And Layering Techniques On The Fracture Resistance Of Maxillary Premolars, Hend Sayed Ahmed, Mohamed Fouad Haridy, Radwa Nagy, Shimaa Elsayed Elhusseiny

Dentistry

Abstract

Objectives: This study aimed to evaluate the fracture resistance of premolar teeth with standardized mesio-

occluso-distal (MOD) cavities, restored using various techniques (layering techniques and composite-resin

restorations)

Materials and Methods: Seventy intact maxillary premolars with standardized MOD cavities were randomly

divided into seven groups (n=10): G1 control intact teeth; G2: MOD cavities left unrestored; G3: restored using an

incremental technique with nanohybrid resin composite (Neo Spectra TM ST, Dentsply Sirona); G4: restored in

bulk using a flowable composite (SDR Flow+, Dentsply Sirona); G5: bulk-filled with a multihybrid composite

(Tetric N Ceram, Ivoclar); G6: restored using an incremental technique with …

Fracture Resistance Of Maxillary Premolars Restored With Different Dentin Replacement Protocols, Hend Sayed Ahmed, Shadwa Hatem Kabil, Maha Elbaz

Dentistry

Aim: The aim of this research was to investigate the fracture resistance of premolar teeth with standardized

mesioocclusodistal (MOD) cavities restored with different dentin replacement protocols.

Subjects and methods: Sixty sound maxillary premolar teeth with standardized MOD cavities were assigned

to six groups (n=10): G1: sound teeth (positive control); G2: unrestored premolars with MOD cavities

(negative control); G3: restored incrementally with nanohybrid resin composite; G4: restored by bulk fill

flowable followed by nanohybrid resin composite; G5: restored with packable fiber-reinforced composite

followed by nanohybrid resin composite and G6: restored with flowable fiber-reinforced composite followed

by nanohybrid resin composite. After being …

Evaluation Of Marginal And Internal Fit In Cad/Cam-Fabricated Indirect Restorations, Mohamed Salama, Sara Adel Botros, Hend Sayed Ahmed

Dentistry

Objectives: This study investigated the effect of marginal adaptation and internal fit of premolar teeth restored with indirect overlays, fabricated from different CAD/CAM materials (lithium-disilicate and composite blocks). Materials and Methods: Twenty-two intact premolars with standardized concave chamfer overlay preparation were divided into two groups (n= 18) Group (A): lithium disilicate blocks and Group (B): composite blocks. All groups cemented with dual cured resin cement. After 24h of storage at 37°C followed by thermocycling. Marginal gap evaluation evaluated using a stereomicroscope at x50 magnification at 4 points at each surface. Specimens were then sectioned mesiodistally to assess internal fit. Statistical …

Validation Of Salivary Proteomic Biomarkers For Early Detection Of Oral Cancer In The Egyptian Population, Dalia Ghalwash, Ahmed M. Ammar, Ayman El-Gawish

Dentistry

Purpose: The present study evaluated the sensitivity and specificity of important proteomic salivary biomarkers; IL-6, IL-8, and sCD44 in the early detection of oral cancer, and any poss associations with risk factors of oral cancer in an Egyptian population Methods: The present investigation was conducted on 100 individuals; 25 healthy controls, 25 patients having oral potentially malignant disorders (OPMDs) with dysplasia; 25 patients having OPMDs without dysplasia, and 25 oral cancer patients. Demographic data modified gingival index, oral hygiene level, and salivary levels of the biomarkers were assessed. Results: Salivary levels of IL-6, IL-8, and sCD44 progressively increased with increased …
