The use of artificially synthesized pharmaceutical drugs are not generally preferred as they may have adverse effects on the body. So natural alternatives are increasingly used for the treatment or prevention of various diseases. Olive oil obtained from olive (the fruit of Olea europea) has a variety of health benefits and it is a very effective naturally available alternative. In this article, the health benefits of olive oil with a special regards to the oral cavity are discussed. Olive oil is used to treat heart diseases, cancer, plaque formation and many more conditions. It has antimicrobial, antioxidant, antiviral and also anticancerous action to an extent.

... Research by Shaw et al., [5] displayed the impact, the dentofacial appearance had on the interpersonal relations of a person. The aesthetics of smile is dependent on a multitude of factors such as facial midline, smile line, smile arc, type of smile, any apparent discolouration, black triangles, buccal corridors and so on [6][7][8][9][10][11]. Garber and Salama suggested that these factors have a comprehensive effect on smile, and the esthetics mainly depend on three primary components: The teeth, gingival scaffold and the lips [12][13][14][15]. ...
... The clinical success and longevity of any prosthetic restoration is dependent on accurate recording of the surface that receives the restoration [1][2][3][4]. In terms of the dental crowns the relationship between the health of the periodontium and the restoration of the teeth is inseparable [5][6][7][8]. As much as it is necessary to record the prepped tooth surface and the finish lines; it is equally important to maintain the health of the periodontium [9][10][11]. ...
Background: Olive oil is a natural source of phytoestrogens and antioxidants similar to mammalian estrogen. The substance increases osteoblast differentiation and osteoprotegerin (OPG) expression. Objective of the study: To examine the effect of giving olive oil on OPG expression of gingival crevicular fluid in the orthodontic tooth movement among old and young guinea pigs. Methodology: The four groups of guinea pigs (n = 3) consisted of old guinea pigs given olive oil (OO), old controls (OC), the young given olive oil (YO), and young controls (YC). The teeth were movedreciprocally to distal by a 0.35 N open coil spring which was attached to the bracket of the lower incisors. The YO group was given olive oil at 0.7ml/day dosage and the OO group had 1.86ml olive oil administered per day until day 14. OPG expression was analyzed in gingival crevicular fluid (GCF) sample using the enzyme-linked immunosorbent assay (ELISA) on days 0, 7, and 14. Retrieved data was analyzed using Three-way ANOVA Statistic Test followed by Post Hoc LSD Test. Results: The statistical test showed that olive oil increased OPG expression in old and young guinea pigs (p<0.05), and OPG OO expression was comparable to that in YC day 7. OPG YO expression was higher than OO (p <0.05). Increasing duration of olive oil application led to higher OPG expression (p <0.05). There was a correlation between olive oil and age and duration of administration (p <0.05). Conclusion: Olive oil increased the OPG expression on GCF of old and young guinea pigs during orthodontic tooth movement, with the highest OPG expression in YO day 14.
Acne is the most common skin problem which can occur due to a bacterial infection. Cinnamon bark oil contains cinnamaldehyde and other active compounds which have antibacterial activity. Olive oil is also known to have antibacterial activity and can reduce skin irritation from cinnamon bark oil application. The nanogel system is known to be suitable for the delivery of active compounds to treat acne. This research aims to develop nanogel preparations containing cinnamon bark oil and olive oil and characterize the gels' physical properties and antibacterial activity against Propionibacterium acnes. The antibacterial activity test of cinnamon bark oil and preparations were carried out by the diffusion method using the perforation technique. Nanogels were prepared using tween 80 as a surfactant, PEG 400 as a co-surfactant, and Viscolam as a gelling agent. The nanogels were characterized by organoleptic, pH, viscosity, spreadability, percent transmittance, globule size diameter, and stability tests. The result showed that cinnamon bark oil has antibacterial activity against Propionibacterium acnes with a MIC value of 0.2%. Nanogel preparations containing cinnamon bark oil (2; 3; and 4%) and olive oil (2%) have good physical characteristics and stability with a clear appearance with an average globule size 129 ±17 nm; 132 ± 18 nm; and 135 ± 19 nm, respectively. Nanogel preparations have potent antibacterial activity against Propionibacterium acnes. The antibacterial activity of the gels depends on oil concentration.

The emergence of an unusual Corona virus (COVID-19) flu pandemic starting in China in December 2019, spreading all around the globe is a major threat to public health. The investigations have shown this virus originated from a seafood market in Wuhan. However, the unavailability of medicines for the new disease is a big challenge all around. An attempt has been made in the present article to familiarise about the morphology of the virus. The study of effect of pH, temperature and relative humidity is also depicted. Various preventive measures have also been discussed. The natural dietary measures suggested in the paper would be very beneficial to improve and boost the immunity of the mankind.
