Not everyone is born with a  perfect teeth , some are lucky to be born with perfect teeth.Orthodontic treatment has now marked a revolutionary change in Dentistry, it helped to restore the smile with the help of Dental braces .Using this modern Dental technology it is now possible to bring back healthy and beautiful smile quicker. TYPES OF DENTAL BRACES Old-fashioned braces use elastic ties – which can cause painful friction – to hold the straightening wire in place.  They are made from a high-grade stainless steel and have metal brackets that are attached to each tooth using a type of cement. The brackets are linked to each other with a thin archwire, which puts pressure on the teeth to cause them to move slowly into the correct position.The ties are also prone to collecting plaque, which can be unpleasant. They are durable and strong. Ceramic Braces  : Made of Ceramics instead of Metal, they have clear or tooth colored brackets so they are less noticeable th...

DENTAL RADIOGRAPHY- A Short Note

By -

Radio graphs (X-rays) are necessary for the evaluation and diagnosis of many oral conditions and diseases. Dentists use radiographs for many reasons: to find hidden dental structures, malignant or benign masses, bone loss, and cavities. They are diagnostic, but they can also be preventative, by helping a dentist diagnose potential oral care issues in a patient’s mouth before they become a major problem. An x-ray is a type of energy that passes through soft tissues and is absorbed by dense tissue. Teeth and bone are very dense, so they absorb X-rays, while X-rays pass more easily through gums and cheeks.X-rays are divided into two main categories, intraoral and extraoral. Intraoral is an X-ray that is taken inside the mouth. An extraoral X-ray is taken outside of the mouth. Intraoral X-rays are the most common type of radiograph taken in dentistry. The benefits of X-rays are well known: They help dentists diagnose common problems, such as cavities, gum dise...

Titanium as a Bio-Material

By -

Titanium is a strong and lightweight refractory metal. It is a lustrous  transition metal  with a silver color, low density, and high strength. Titanium is also formidable in its resistance to corrosion by both water and chemical media.It does this by forming a thin layer of titanium dioxide (TiO2) on its surface that is extremely difficult for these materials to penetrate.Having a low modulus of elasticity means that titanium is not also very flexible, but returns to its original shape after bending, resulting in its importance to shape memory alloys. Titanium is non-magnetic and biocompatible (non-toxic, non-allergenic), which has led to its increasing use in the medical field. An ideal biomaterial is expected to exhibit properties such as a very high biocompatibility, that is, no adverse tissue response. Also, it must have a density as low as that of bone, high mechanical strength and fatigue resistance, low elastic modulus and good wear resistance. It is...
