Apically Extruded Debris and Irrigant Using the Revo-S System

Chemomechanical preparation, by endodontic instrumentation and the use of intracanal irrigants, is an integral part of root canal therapy. During these procedures, there is always a possibility of pulp tissue fragments, dentine chips, necrotic tissue,microorganisms and intracanal irrigants being extruded beyond the apical foramen even when the working length is controlled. 


The extrusion of debris apically may have the potential to disrupt the balance between microbial assault and host defense leading to the development of acute inflammation and flare-ups. Studies have shown that instrumentation techniques utilizing a push-pull motion tend to extrude more debris than those incorporating rotational motions. This has lead to the hypothesis that engine driven rotary instruments extrude less debris than hand filing techniques. Read more>>>>>>>>>

Harvesting Free Palatal Masticatory Mucosal Graft Using 3a Mucotome

Image
The technique of free autogenous gingival grafting (FGG) has undergone little modification since its introduction by Bjorn in Scandinavia in 1963 and by King and Pennel inthe United States in 1964. The technique is widely used to treat a variety of mucogingival problems such as insufficient or lack of attached gingiva, the presence of high frenum attachments, shallow fornix and denuded roots following gingival recession.  FGG can be procured from donor site using scalpels, gingivectomy knife or palatal shaving knife (Paquette knife). The donor site is frequently the palate, although the use of edentulous ridge areas, tuberosity and attached gingiva has also been described. Scalpel is most commonly used and conventional method for procuring gingival auto grafts. Gingivectomy knife, although not commonly used, also works on similar principle. Since the scalpel blade is straight and stiff and the palate is curved, repeated incisions to release the graft from underlying conn...

Indications for Orthognathic Surgery

Image
Orthognathic surgery (OS) is a surgical intervention that alters relationships of the jaws and dental arches. The treatment involves a combination of orthodontics and maxillofacial surgery.  Orthognathic Surgery It is used to correct dentofacial deformities that cannot be treated with acceptable results by conventional orthodontics. The first description of a surgical intervention to correct a malocclusion was by Hullihen in 1849. The most frequently used surgical procedures for correcting the relationship of the jaws are Le Fort I osteotomy and sagittal ramus split osteotomy. Also often used are vertical ramus osteotomy, inverted L osteotomy, and variations and combinations of the above. Read More>>>>>>

Micro-Implant Anchorage for Orthodontic Treatment of Bialveolar Protrusion

Image
Conventional methods of reinforcing orthodontic anchorage have several disadvantages, including complicated appliance design and the need for exceptional patient cooperation. Kanomi and Costa et al.   introduced the use of titanium microscrews and miniscrews for orthodontic anchorage. Microscrews are small enough to place in any area of the alveolar bone, easy to implant and remove, and inexpensive.    In addition, orthodontic force application can begin almost immediately after implantation. In particular, microscrews have been shown to produce en masse retraction of the six anterior teeth. So it was decided to use micro-implants to treat a patient having Class 1 bialveolar protrusion where anchorage demands are critical. The patient, a 15-year-old female, had a convex profile and a Class I skeletal pattern with bialveolar protrusion Cephalometric analysis showed an ANB angle of 4°, a mandibular plane angle (FMA) of 20° and facial angle of 88°.
