This review paper aimed to evaluate the effect of oxidative stress in the prevalence of some dental diseases and the role of antioxidants in dentistry. Oxidative stress is a normal phenomenon, present in healthy human body help them to produce energy that they need for their life. During that, the formation of free radicals begins, including both reactive oxygen species "ROS" & also reactive nitrogen species "RNS". These radicals have a role in a many types of signalling pathways that regulate inflammation. Antioxidants constrain the formation of free radicals. Mitochondria, a small cell organelle acts to generate energy in the form of adenosine triphosphate "ATP". It combines oxygen & glucose to form carbon dioxide, water, & ATP. Free radicals result as by-products of this metabolic process & when natural defence apparatuses be unsuccessful, the level of free radicals begins to increase to levels where the capacity of the body is unable to neutralize them entering the body into the state of high oxidative stress, which means greater risk of numerous oral & systemic diseases. Oral tissues are liable to free radical damage in a unique manner due to the presence of mucus membranes that allow rapid absorption of constituents throughout their surfaces. In oral environment, infection of gingiva can produce oxidative stress. The rise in formation of free radicals by oxidative stress results in further destruction of cellular walls and oral tissues. The study results suggested that the use of antioxidants is an adjunct approach to dental therapy may be helpful in controlling the oral health status.

Aims: The study aimed to evaluate the effect of smear layer on the push-out bond strength of silicone-based root canal sealers. Materials and methods : Sixty extracted, single-rooted, sound human mandibular first premolar teeth were selected for this study. The Crown portion of each tooth was decoronated to the level of cement-enamel junction to standardize the root length to 16 mm. The working length was measured by subtracting 1mm from the visually determined canal length and the canals were instrumented using ProTaper universal rotary system up to size F3. The canals were divided into two groups according to the irrigating solutions used. Group.1 was rinsed with 2.5% sodium hypochlorite followed by 17% EDTA to ensure complete smear layer removal. Group.2 was rinsed using 0.9% normal saline to keep the smear layer. Then the samples were subdivided into three subgroups according to the sealer used with gutta-percha. These include AH Plus, GuttaFlow 2, and GuttaFlow Bioseal groups. The push-out bond strength test was performed using the universal testing machine and the data were analyzed using independent sample T-test at (p ≤ 0.05) to compare the results of each sealer group in the presence and absence of the smear layer. Results: For all sealers’ groups the results has shown a statistically significant difference in the bond strength at (p ≤ 0.05) between group 1 (without smear layer) and

Aims: To study the effect of metal oxide nanoparticles (MgO, ZrO2, ZnO) on acrylic based soft liner surface properties and FTIR. Materials and Methods: Acrylic-based soft-liner specimens were prepared by adding three different concentrations (0.5, 1, and 2) %wt of metal oxide nanoparticles (MgO, ZrO2, ZnO). A disk-shaped specimens with 30mm diameter and 3mm thickness were prepared for shore (A) hardness test to evaluate the surface hardness of modified soft liner. The surface roughness of soft-liner samples (10X10X2mm) was tested by a profilometer. FTIR analysis was conducted to evaluate chemical reaction that may occur between acrylic-based soft liner and nanoparticles. Results : there were no chemical reaction carried out between soft liner and metal oxide nanoparticles at different concentration- surface hardness (shore A) was increased as nanoparticles concentration increased in modified resin. Nanoparticles with 1 and 2% concentration incorporated in soft liner had lower surface roughness value. Conclusions : Metal oxide nanoparticles have improved the surface texture of acrylic-based soft liner, while the hardness of modified soft liner was increased with nanoparticles concentration increases.
