VELscope : An Oral Assesment System

Image
  The VELscope System is a revolutionary hand-held device that provides dentists, hygienists, and other oral health care professionals with an easy-to-use adjunctive mucosal examination system for the early detection of abnormal tissue. It is a brand new oral cancer screening system which helps in early detection of oral cancer. The  VELscope  is a blue excitation lamp, which highlights precancerous and cancerous cell changes. Clinical trials demonstrated that sensitivity of  VELscope  in detecting malignancy ranged from 22 % to 100 % and specificity ranged from 16 % to 100%. Most studies concluded that  VELscope  can help the experienced clinician to find oral precursor malignant lesions.   Developed by BRITISH COLUMBIA CANCER AGENCY about 10 years ago and is approved by FDA and recognized by WORLD HEALTH ORGANISATION .   The VELSCOPE Vx enhanced oral assessment system centers on a handheld scope and a 12 MP high resolution digital camera that is being used by dentists t

BONE GRAFTS

What are bone grafts? Bone grafts are the materials used for replacement or augmentation of the bone. ·          Enhances regenerative capacity of bone ·          Achieve new attachment apparatus Biologic concept of using bone graft: 1.       Osteoconduction 2.       Osteoinduction 3.       Osteogenesis OSTEOCONDUCTION (Trelli’s effect): “ Physical effect” by which the matrix of the graft forms a scaffold that favors outside cells to penetrate the graft and form new bone . E.g: Alloplast, FDBA OSTEOINDUCTION: Chemical process by which molecules contained in the graft (e.g., bone morphogenetic proteins) convert the neighboring cells into osteoblasts, which in turn form bone . E.g: DFDBA OSTEOGENESIS: Osteoblasts in the transplanted bone    having adequate blood supply & cellular viability forms new     centers of ossification within the graft. E.g: Autogenous graft   INDICATIONS FOR GRAFTS 1.       Deep Intraosseous Defects 2.       Tooth Retent

PERI- IMPLANTITS

Image
  INTRODUCTION   D ental implants have become a critical necessity for replacement of lost natural teeth in modern times. Although implants are considered to be a predictable treatment option, peri‑implant diseases do occur, posing significant challenges for both – the clinician and patient.Implant success is only defined as a short‑term effect that is, whether the implant has osseointegrated or not and whether it is able to support a restoration following its placement. There are no proper guidelines that define implant success or maintenance over a long‑term, except for implant survival. In the last decades increasing evidence raised on the presence of peri-implant inflammations representing one of the most frequent complications affecting both the surrounding soft and hard tissues which can lead to the loss of the implant.   The term “peri‑implantitis” was introduced to describe an inflammatory process caused by microorganisms affecting the supporting tissues around an osse
