OBJECTIVE To compare the efficacy of gutta-percha removal achieved with simple mechanical technique using two different solvents. MATERIALS AND METHODS It was an in vitro experimental study conducted at the Aga Khan University Hospital, Karachi, Pakistan on 27 extracted human molars divided into two groups by alternate sampling technique. The teeth were prepared by manual filing and obturated...
BACKGROUND Labor is a stressful situation that may have an adverse impact. Aromatherapy is a method to control anxiety and stress of women. This study was conducted to investigate the effect of aromatherapy using essential oil of orange on women's anxiety during labor. MATERIALS AND METHODS In this clinical trial study, 100 women during labor were randomly assigned to two groups: intervention...
INTRODUCTION The aim of this in vitro study was to evaluate the dissolving efficacy of eucalyptol and orange oil solvents associated with passive ultrasonic activation (PUA) in zinc oxide-eugenol (ZOE) based and epoxy resin-based root canal sealers. METHODS AND MATERIALS Seventy samples of each sealer were prepared and then randomized according to the solvent and the time of the ultrasonic ac...
In this study, the effect of glycerol (0.5, 1 and 1.5% w/w) and vegetable oil (2, 3 and 4% w/w) on the equilibrium headspace concentration of target volatile flavor compounds released from the orange beverage emulsions during storage was investigated by using the headspace solid phase microextraction (HS-SPME). The peak areas of 13 target orange flavor compounds (i.e. ethyl acetate, α-pinene, e...
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Majority of the cosmetic products available in market are synthetic origin and causes numerous side effects when used for longer period time. One solutions this problem is use herbal cosmetics. Herbal cosmetics considered safe routine with minimal effects. Acne, redness, wrinkles, dark circles, pimples, dry dead skin some major issues. All these problems can be minimized by using such as face p...
This study evaluated the removal of filling material with ProTaper Universal Rotary Retreatment system (PTR) combined with solvents and the influence of solvents on the bond strength (PBS) of sealer to intraradicular dentin after canal reobturation. Roots were endodontically treated and distributed to five groups (n = 12). The control group was not retreated. In the four experimental groups, ca...
This work aimed to study the effect of emulsion properties on the microencapsulation of orange essential oil by spray drying. The study was performed using a 2 central composite design, where the independent variables were the total solid content (0-30%), the ratio of oil/total solids (0-30%) and the homogenization pressure used for emulsification (0-1000 bar). Whey protein concentrate and 20 D...
Fragrances are widely used in topical formulations and can cause photoallergic or phototoxic reactions. To identify phototoxic effects, 43 fragrances were evaluated in vitro with a photohaemolysis test using suspensions of human erythrocytes exposed to radiation sources rich in ultraviolet (UV) A or B in the presence of the test compounds. Haemolysis was measured by reading the absorbance value...
