Oral Biology Seminar BPKIHS BDS 2014

Every year second year BDS students of B.P. Koirala Institute of Health Sciences, Dharan  are given an opportunity to present on specified topics related to Oral Anatomy and Histology with a goal of honing their presentation skills and boosting their confidence. The Seminar topics were provided by the Department of Oral Pathology, College of Dental Surgery. The presentation files of the Seminar can be downloaded by clicking on the respective topics.

Toothpastes or Dentrifices : Composition and properties

Imagine a single day when you had forgotten to brush after two consecutive meals. Remember that feel of rough texture of your own tongue over your teeth and that sensation of your own bad breath. How would our life become if we did not have this magical product formulated till today? Could we enjoy the close-up breathy talks or make our beloved ones feel special by kissing them? Let’s forget kissing! I doubt whether we will be comfortable even to talk face to face.

Why should we study about dental materials ?

Dentistry is a science which requires a great knowledge required for diagnosing the clinical problems accurately and framing a treatment plan which best fits the requirement of patient. The dentist should be well aware about the physical and chemical properties of the material that is being used in the intraoral as well as extra oral environment of the patient. Many tools and materials are needed in dental practice which seem too vast to learn about and use them appropriately.

 As a first year or a second year dental student, you might be disinclined to study about the dental materials. “Why on earth do we have to study about these compositions of cements and the amalgam when we even don’t know their use?”

Tips to Study Faster and Effectively

Every one of us might have experienced time and again that we are too close to the upcoming exam to prepare well for it. When there is plenty of time, we often keep on procrastinating. Even the things which we are not interested about start becoming more interesting and we lose our time simply doing nothing.

This time pressure is especially seen in medical and dental students who have to take hours long lectures daily along with the laboratory exercises and case studies to complete.
The assignments and seminars on the top of that makes everybody feel like it is never possible to prepare thoroughly for the exams. But that is not always the case. Those academic achievers are also like us and they also feel the same way about the time constraint. What makes the difference is that they study effectively as compared to others that makes them “The Outliers”.

The future of amalgam in dentistry : Mercury toxicity

Few decades after its development in France in the 1800s, the controversy regarding the safety of dental amalgam instigated because mercury is the key element in dental amalgam. Considering the toxic effects of mercury to the human health as well as to the environment, its use as a dental restorative material has declined over years.

 Mercury toxicity is a concern in dentistry because mercury and its chemical compounds are toxic to the kidneys and the central nervous system. The most significant danger is from mercury vapor.

Adverse effects on health and teeth due to carbonated soda drinks / soft drinks

Whether it’s a short respite from your work on a hot summer afternoon or a meeting with your college friend after many years, carbonated soda drinks are essentially one of the drinks you consume. Some of the few to name are: Cocacola, Fanta, Sprite, Pepsi, Mountain Dew , Mirinda, etc.
These go harmoniously with any casual fast foods like mo:mo: , chowmein, pizza, burger, etc. So, it’s not absurd if you find yourself drinking 2-3 drinks daily on a regular basis.

But, you might want to know few things about these so called soft drinks, because they are necessarily not as soft as you might have assumed
