A Patient’s Guide to Orthognathic Surgery
October 2011
Orthognathic surgery (jaw surgery) is a term and a process unfamiliar to most people.

Impacted Maxillary Central Incisor with Mesiodens – Treatment Protocol
October 2011
At your clinical examination, the alveolus in the right central incisor region appears fairly wide or perhaps a little bulky and it certainly feels as though there is a tooth underneath the mucosa. You prescribe a periapical radiograph which clearly shows a supernumerary conical tooth, with little or no root development, superimposed on the image of what appears to be a normal, but displaced, central incisor. The root of this incisor is well over 2/3 of its final root length, although its apex is still open and the tooth itself is quite high in the alveolus.
An in-vitro study to assess the biohostability of Orthodontic arch wires to Hepatitis B virus
October 2011
The risk of occupationally acquiring infection is significant among orthodontic professionals because orthodontic treatment procedures involves the use of arch wires, ligature wires, band material and other sharp cutting instruments constantly in contact with saliva and blood. Any percutaneous injuries by these sharp materials can be the principal source of transfer of Hepatitis B virus. The quantum of blood required to transmit Hepatitis B virus is 0.0004ml while for HIV it is only 0.1ml Hepatitis B virus is perhaps the most common blood-borne infection in the world.
