Combined remembered Qs 2020 December 6&7 RQ’s: 1. Best cement for temporary crowns- -Polycarboxylate temporary luting cements present low postoperative sensitivity, adequate retention, and ​ ​ easy cleanup. Examples of this category are: Cling2 (CLINICIAN'S CHOICE) and Hy-Bond (Shofu Dental). ​ ​ -ZOE temporary luting cements are commonly used because of their sedative effect on sensitive teeth. It is well ​ ​ documented that eugenol is able to penetrate and diffuse throughout the dentin and can affect the bond strengths provided by resin materials used for definitive restorations. It presents an excellent antibacterial effect. -ZONE temporary luting cements are designed to replace eugenol with various types of carboxylic acids that do ​ ​ not interfere with definitive cementation. They have the characteristics of being compatible with resin provisional materials, are compatible with permanent resin cements, and show greater retention compared to ZOE cements but have no sedative effect on the pulp. -Resin temporary luting cements present high strength, excellent retention, better aesthetics, and easy cleanup. However, these temporary cements have a higher incidence of microleakage, discoloration, and odor associated with their use. 2.

  • Natural History of Odontogenic Infection
    Natural History of Odontogenic Infection The usual cause of odontogenic infections is necrosis of the pulp of the tooth, which is followed by bacterial invasion through the pulp chamber and into the deeper tissues. Necrosis of the pulp is the result of deep caries in the tooth, to which the pulp responds with a typical inflammatory reaction. Vasodilation and edema cause pressure in the tooth and severe pain as the rigid walls of the tooth prevent swelling. If left untreated the pressure leads to strangulation of the blood supply to the tooth through the apex and consequent necrosis. The necrotic pulp then provides a perfect setting for bacterial invasion into the bone tissue. Once the bacteria have invaded the bone, the infection spreads equally in all directions until a cortical plate is encountered. During the time of intrabony spread, the patient usually experiences sufficient pain to seek treatment. Extraction of the tooth (or removal of the necrotic pulp by an endodontic procedure) results in resolution of the infection. Direction of Spread of Infection The direction of the infection's spread from the tooth apex depends on the thickness of the overlying bone and the relationship of the bone's perforation site to the muscle attachments of the jaws. If no treatment is provided for it, the infection erodes through the thinnest, nearest cortical plate of bone and into the overlying soft tissue. If the root apex is centrally located, the infection erodes through the thinnest bone first. In the maxilla the thinner bone is the labial-buccal side; the palatal cortex is thicker.

  • Optimum Ortho with Removable & Fixed Appliances
    1 #39 Ortho-Tain, Inc. 1-800-541-6612 OPTIMUM ORTHODONTICS FOR THE 5 TO 12 YEAR-OLD BY COMBINING REMOVABLE AND FIXED APPLIANCES WITH THE USE OF THE NITE-GUIDE AND OCCLUS-O-GUIDE APPLIANCES INTRODUCTION: Early intervention of common orthodontic problems seen developing in the late deciduous dentition as the mandibular incisors begin to erupt is frequently made more efficient by a combination of appliances. For example, the Nite-Guide technique is an efficient means of preventing overbite, increasing arch development and correcting overjet. There often develops, however, a shortage of arch size for cases where, (a) the maxillary canines erupt in a mesial direction, (b) there is a bi-lateral constriction of the upper arch, (c) where the upper permanent molars are positioned too far mesially or have been rotated mesio-lingually; due to loss of arch length from deciduous molar loss or decay, (d) where there is insufficient arch development for the incoming (upper and/or lower) incisors, (e) where persistent thumb or finger sucking is preventing the full eruption of permanent incisors, and (f) incomplete eruption, rotation and torque corrections of the permanent teeth. These six examples of problems can be associated with the use of the Nite-Guide technique and can also occur in the mixed dentition when the Occlus-o-Guide would be used. These six problems are usually easily rectified by various forms of limited fixed appliance methods and associated appliances such as the quad-helix, cervical head-gear, and maxillary and/or mandibular bumpers, rapid palatal expanders, anti-thumb sucking appliances as well as various other removable appliances.

Nagda1, Dr. Uma B. Dixit2 1Post-graduate student, Department of Pedodontics and Preventive Dentistry, DY Patil University – School of Dentistry, Navi Mumbai, India 2Professor and Head,Department of Pedodontics and Preventive Dentistry, DY Patil University – School of Dentistry, Navi Mumbai, India Corresponding Author: Dr. Shreya C. Nagda Abstract:Malocclusion poses a great burden worldwide. Persistent oral habits bring about alteration in the activity of orofacial muscles. Non-nutritive sucking habits are shown to cause anterior open bite and posterior crossbite. Abnormal tongue posture and tongue thrust swallow result in proclination of maxillary anterior teeth and openbite. Mouth breathing causes incompetence of lips, lowered position of tongue and clockwise rotation of the mandible. Early diagnosis and treatment of the orofacial myofunctional disorders render great benefits by minimizing related malocclusion and reducing possibility of relapse after orthodontic treatment. Myofunctional appliances or pre orthodontic trainers are new types of prefabricated removable functional appliances claimed to train the orofacial musculature; thereby correcting malocclusion. This review aimed to search literature for studies and case reports on effectiveness of pre-orthodontic trainers on early correction of developing malocclusion. Current literature renders sufficient evidence that these appliances are successful in treating Class II malocclusions especially those due to mandibular retrusion. Case reports on Class I malocclusion have reported alleviation of anterior crowding, alignment of incisors and correction of deep bite with pre-orthodontic trainers.

Parmar, Govt. medical college, Nahan Abstract Molar scissor-bite is a common finding in orthodontics and many times, it can be found as a sole malocclusion in a patient. Alignment of such buccally erupted molars is a challenging task. This article describes a modified use of conventional quad helix appliance to correct scissor bite in a growing child. Keywords: Scissor bite, malocclusion, quad helix, early treatment. Introduction techniques.[1,5] Scissors bite, also known as buccal crossbite is Cross elastics have a disadvantage of extrusion of the buccal occlusion of the maxillary teeth with the molars and also require patient compliance. Many palatal mandibular teeth and can be classified as complete cantilever arches are designed which are activated with or incomplete, unilateral or bilateral.[1] In the young e-chains. These are difficult to manage clinically and patient scissor bite may not be urgent, but it can hide a require frequent activations due to e-chain’s faster force problem with the temporomandibular joint (TMJ) that decay. Pulling the upper molar palatally with elastic can become manifested with growth.[2] This abnormality traction from a single palatal implant causes the crown may not resolve by itself and if left untreated would of the tooth to tilt lingually, burying its lingual cusps affect chewing and muscle function and may impair into the mucosa, posing problems in banding the molar normal growth and development of the mandible.

E-mail: [email protected] Summary Objectives: Insufficient attention is given in the literature to the early treatment of anterior open bite (AOB) subjects receiving orofacial myofunctional therapy (OMT), which aims to harmonize the orofacial functions. This prospective pilot study investigates the effects of OMT on tongue behaviour in children with AOB and a visceral swallowing pattern. Materials and methods: The study comprised of 22 children (11 boys, 11 girls; age range: 7.1– 10.6 years). They were randomly assigned into OMT and non-OMT subjects. The randomization was stratified on the presence of a transversal crossbite. At baseline (T0), at the end of treatment (T1) and at 6 months after T1 (T2) maximum tongue elevation strength was measured with the IOPI system (IOPI MEDICAL LLC, Redmond, Washington, USA). Functional characteristics such as tongue posture at rest, swallowing pattern and articulation and the presence of an AOB were observed.
