World Oral Health Day 2018 was celebrated by multiple events like poster and flex competition, Speech competition and Table Clinic Competition. College of Dental Surgery, BPKIHS in coordination with Nepal Dental Association, Sunsari, organized the program. Also, 4th year BDS students as a part of their social responsibility for public awareness acted out a play regarding health hazards of drinking, smoking and chewing areca nut. The winners of Poster competition were Shabnam Gurung and Pratima Rai of BDS 2014 batch and the winner of Table Clinic Presentation were Anumesh Dahal and Nitika Santhaliya.

The American Society for Testing and Materials (specification D 907) defines adhesion as “the state in which two surfaces are held together by interfacial forces which may consist of valence forces or interlocking forces or both.” (ref. 2) In dentistry, bonding of resin-based materials to tooth structure is a result of four possible mechanisms, as follows: (ref. 3) Mechanical Adsorption Diffusion Combination of above three For good adhesion, close contact must exist between the adhesive and the substrate (enamel or dentin). The surface tension of the adhesive must be lower than the surface energy of the substrate. ENAMEL Acid-etching transforms the smooth enamel into an irregular surface and increases its surface free energy. When a fluid resin-based material is applied to the irregular etched surface, the resin penetrates into the surface, aided by capillary action. Monomers in the material polymerize, and the material becomes interlocked with the enamel surface...

Cimetidine increases the plasma half life of circulating lidocaine. So this combination is relatively contraindicated in CHF patients. Esters such as procaine and tetracaine may inhibit the bacteriostatic action of sulfonamides. The administration of adrenaline in patients being treated with non-selective beta blockers (such as propranolol, tinolol, atenolol, increases the likelihood of serious elevation of the blood pressure. Tricyclic antidepressants (eg: Imipramine) and monoamine oxidase inhibitors (eg: Isocarbaxazid) potentially increase the cardiovascular actions of exogenously administered vasopressors.
