Materials and methods: An overall of 32 elevated carious index adult patients with at least one carious class V cavity on their posterior teeth had been split into 2 equal groups randomly based on the received restoration system. Two pairs of restorations were used, either; Equia Forte HT Fill (AGH) or Fuji II LC (RMGI), both materials were employed in accordance with the manufacturer's guidelines. Fillings have …

Bond Strength Of Thermally Aged Cad/Cam Hybrid Nanoceramic Repaired With Nanohybrid Resin Composite, Mostafa Aboushahba, Sara H. Younis

Future Dental Journal

Purpose. To assess shear bond strength (SBS) of nanohybrid resin composite used to repair CAD/CAM Hybrid Nanoceramic ceramic after various surface treatments.

Materials and Methods. SHOFU HC Hybrid Ceramic disks were sliced to obtain circular-shaped specimens (n= 30) were obtained. All specimens were thermocycled (5000 thermal cycles), then specimens were divided into three groups according to the surface treatment performed (sandblasting, HF acid etching, and laser irradiation) (n = 10). Repair procedure with nanohybrid resin composite was performed. SBS values were obtained, and failure modes were determined. Data were statistically analyzed (P ≤ 0.05). Results. The highest SBS …

Evaluation Of Blending Ability Of Single-Shade Composite Relating To Different Cavity Depths And Abrasive Wear From Toothbrushing, Nattaporn Verayangkura

Chulalongkorn University Theses and Dissertations (Chula ETD)

Materials and Method: Eighty extracted human premolars were used for the shade‑matching evaluation. The materials tested in this study were Omnichroma (OC), Vittra APS Unique (VU), Charisma Diamond One (CD), and Filtek Z350 XT (FZ, control). The initial tooth shade was determined using a dental spectrophotometer and the reference color parameters (L, C, and H) were recorded with a laboratory spectrophotometer. A 4‑mm‑diameter cylindrical cavity was prepared in each tooth at restoration depths of either 1 mm or 2 mm. The prepared teeth in each restoration depth group were further divided into four subgroups based on the resin composite material …

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 …
