Composite the ultimate material for minimally invasive dentistry(Hybrid Composites,Micro filled Composites,Nano filled composites)

Educational Objectives Upon completion of this course, participants should be able to achieve the following: • Understand what the three classification systems in composite materials and what their indications. • Learn clinical tips for Class I and Class II direct posterior restorations. • Learn layering techniques to build in dentinal lobes, incisal edge effects and incisal halos. • Learn simple polishing techniques to create the appropriate finish and luster. Introduction Used in Class I, II and IV restorations in the posterior and anterior regions, composite resins represent an attractive restorative option for patients who desire minimally invasive treatment or cannot afford more costly indirect alternatives. Among the most versatile materials, composites might be used in direct restorations, build-ups, cements, diagnostic mock-ups, gingival stabilization, provisionals and prototypes. Although previous direct composite generations have demonstrated polymerization shrinkage and the...

Atelectasis Partial lung collapse

Atelectasis is the collapse of part or (much less commonly) all of a lung.  Atelectasis may be an acute or chronic condition. In acute atelectasis, the lung has recently collapsed and is primarily notable only for airlessness. In chronic atelectasis, the affected area is often characterized by a complex mixture of airlessness, infection, widening of the bronchi Atelectasis Partial lung collapse Classification Atelectasis may be an acute or chronic condition. In acute atelectasis, the lung has recently collapsed and is primarily notable only for airlessness. In chronic atelectasis, the affected area is often characterized by a complex mixture of airlessness, infection, widening of the bronchi (bronchiectasis), destruction, and scarring (fibrosis). Chronic atelectasis may take one of two forms—middle lobe syndrome or rounded atelectasis. In right middle lobe syndrome (also known as Andy Wilson's Disease ), the middle lobe of the right lung contracts, usually because ...

NASAL TEETH - A RARE CASE

                                Eruption of the teeth into the nasal cavity is a rare phenomenon. Ectopic tooth eruption in a non-dental area is a rare entity,   whereas in oral cavity it is most common. The ectopic  development of teeth in non-dental localizations have been  reported in the nasal cavity, chin, maxillary sinus, mandibular  bone, palate and orbital cavity.

What should you wear ?

Medical professions often require their workers to wear uniforms or other special types of clothing due to the nature of the work. Dentists are one such profession and often wear such things as scrubs and lab coats. They may also choose to have a more standard professional appearance. Scrubs Standard scrubs are the typical attire for dentists. Scrubs consist of a pair of pants and a top. Tops may be either short or long sleeve depending on the individual's preference. Pants are always long. Scrubs come in a variety of colors and patterns. White and various shades of blue seem to be the most commonly worn, but these are by no means the only colors worn by dentists. Patterns range from cartoon and movie characters to seasonal prints. Women also have more choices when it comes to styles. They can choose from stereotypical scrub tops or ones that look more like everyday fashion tops made from scrub material. Lab Coats Dentists often wear lab coats over their scrubs. Lab...
