Formulation and evaluation of a face serum containing fenugreek extract

Background: Wrinkles on the face and aging of the skin are an undesirable effect of photodamage and ultraviolet radiation. Serum has a quick absorption and ability to penetrate deep layers of the skin, as well as a non-oily finish and a deep formula with a very high amount of active ingredients. Methods: In this study, we have formulated and evaluated a face serum containing combination of aqueous extract of fenugreek seed and lemon oil. Results: Facial serum was tested for its pH, physical appearance, viscosity, microbial testing, cyclic temperature test, etc. The results of the stability study show that there was no change in visual acuity, homogeneity. Conclusions: Serum containing Fenugreek extract have been able to cure bacterial infections and inflammations of facial skin, and other signs also moistens the skin without any side effects making skin soft, smooth and supple.

Evaluating the effect on tensile bond strength between commonly used acrylic denture base material lined with two variety of soft liners after using three varieties of denture cleansers-an in vitro study

Background: Long-term use of denture causes significant changes in its supporting structures and can lead to constant pain and discomfort. Soft lining material extensively used in field of prosthodontics to improve fit of conventional acrylic resin denture for restoring optimal health of abused oral tissue showing degenerative change. Method: Specially designed metal mould used for fabrication of 80 acrylic resin blocks. Applying soft liner between 2 acrylic sample using metal mould and grouping these samples for immersion in solution of denture cleansers. These acrylic samples were then divided into 2 groups of 40 samples each for applying 2 variety of soft liner for each group (L1 and L2). Keeping specimen in solution of denture cleanser per day for 8 h keeping each specimen 3 times a day=equals to 3 days treatment. Thus, keeping the specimen for 30 days×3 exposure=amount to 90 days (3 months) exposure and then tensile bond strength measured using universal testing machine (Instron). ANOVA test is applied. Results: Tensile bond strength of Viscogel soft liner with acrylic based is decreased with more Polident denture cleanser followed by Efferdent, Clinsodent and least affected by water which is statistically significant. Conclusions: The clinician should choose denture cleanser by considering the microbiologic properties of cleansers and material aspects such as the compatibility of denture cleanser with soft liners.
