Abstract

Background: Chewing gum has been proven to have benefits towards reducing plaque accumulation in oral cavity by mechanical action. The newer sugar- free chewing gums claim additional chemical action towards plaque control. Hence this study was conducted to find out the efficiency of two commercially available xylitol/mannitol containing sugarfree chewing gums in plaque control. Methodology: A single blind randomized control trial was done among twenty patients between 20 to 40 years of age. Two sugar free chewing gums, Protex- Happy Dent and Orbit were used in the study. Quigley-Hein plaque index (QHPI) was used to record plaque score before and after chewing the gums. Post-hoc test and one-way ANOVA was done to find out the statistical significance (p<0.05) in plaque reduction within and between the groups. Result: The mean QHPT prior to chewing for Group 1 (Protex) was 2.9 and for Group 2 (Orbit) was 2.99. After twenty minutes of chewing the gums the QHPI for Group 1 (Protex) were 2.4 and for Group 2 (Orbit) were 2.6. The mean QHPI prior to chewing for two control groups were 2.29 and 2.32. After twenty minutes of chewing mean QHPT was 2.32 and 2.23 respectively. The mean reduction in plaque score between and within the group were statistically significant based on post hoc and one way AN OVA test. Conclusion: The efficiency of plaque reduction in Protex and orbit sugar free chewing gums is 2 to 4 times more when compared to sugared chewing gums. Sugar free chewing gum containing xylitol is more efficient in reducing plaque accumulation when compared to sugared chewing gums.

Abstract

Background: Resin based composite materials, in spite of their numerous advantages are still limited in usage due to lack of certain mechanical properties. Lack of flexural strength is one such weakness. Reinforcing the resin composites with fibres have been shown to improve the strength. This study was conducted to assess the flexural strength of resin composite material reinforced with commercially available polyethylene woven fiber (Ribbond, U.S.A). Methodology: Two groups were made. Group 1 consisted of 30 resin based composite rectangular bar specimens of dimension 25×2×2 mm of length, width and height respectively. Group 2 consisted of 30 resin based composite bar specimens of similar dimension, but reinforced with polyethylene fibers at the middle of the specimen (neutral zone). All the specimens were subjected to three-point bend test and the maximum load at which fracture occurred were recorded and flexural strength were calculated. Results: The mean flexural strength with standard deviation of the group 1 and group 2 were 81.55 ±7.2 MPa and 95.04 ±2.6 MPa respectively. Conclusion: The study concluded that reinforcement of resin based composites with polyethylene, woven fibers significantly increased the flexural strength by 17%.

Root Resorption -A Review

[Year:2012] [Month:January-June] [Volume:2] [Number:1] [Pages:11] [Pages No:12 - 22]

Abstract

A thorough knowledge of the aetiological factors and complex dynamics of the mechanisms involved in root resorption are critical for effective management. Poorly diagnosed and treated cases not only have a debilitating physical impact, but also causes psychological trauma to patients. This further stresses on the need for dentists, and cndodontists in particular, to be able to recognise cases of established resorption or potential to develop into one. Careful case selection and complete inactivation of resorptive tissues are two critical steps in successful management of root resorption. This review will focus on the pathological process ofresorption from a clinician's perspective, and will discuss the various entities ofrcsorption, its features, diagnosis, differential diagnosis, prognosis and treatment. It will also attempt to correlate the actiopathogcncsis to the above mentioned features in order to make the understanding of this obscure pathology clear.

Mini Implants -A Review

[Year:2012] [Month:January-June] [Volume:2] [Number:1] [Pages:5] [Pages No:23 - 27]

Abstract

A common condition in elderly patients is edentulism, which can be the result of many factors such as systemic disorders, poor oral hygiene, dental caries and periodontal disease. The edentulous condition has been shown to have a negative impact on the oral-health related quality oflife. Over the past 2 decades, oral implants which are widely used in the replacement of missing teeth (partial/complete) provide optimum satisfaction and improved quality of life for the patients. However, the determinant factors in the success rate of implants are the quality and quantity of available bone. Mini-implants are nowadays used as an alternative to conventional implants in areas with compromised bone. This review focuses on the role of mini-implants in the rehabilitation of edentulous patients.

Gunning Splint for Intermaxillary Fixation in an Edentulous Patient - A Case Report

[Year:2012] [Month:January-June] [Volume:2] [Number:1] [Pages:3] [Pages No:28 - 30]

GET ACCESS    DOI: 10.5005/jsd-2-1-28  |  Restricted |  How to cite  | 

Abstract

Management of most of the facial fractures especially those of maxilla and mandible rely on proper intennaxillary fixation. Intermaxillary fixation allows immobilization of the reduced and fixed fragments of bone during the healing period. Intermaxillary fixation with or without osteosynthesis can be carried out by using various techniques. The procedure for an edentulous patient demands special considerations since the absence of teeth makes the stabilization much more difficult. This case report explains the steps in fabrication of a gunning splint used for intermaxillary fixation in an edentulous patient.

Ridge Augmentation Technique Using Connective Tissue Graft for the Correction Of Class III Ridge Defects for Esthetic Fixed Partial Denture Construction -A Case Report

[Year:2012] [Month:January-June] [Volume:2] [Number:1] [Pages:5] [Pages No:31 - 35]

Abstract

The structural loss of the residual alveolar ridge can occur as a result of congenital defects, periodontal disease, tooth extraction or surgical procedures. During healing, the overlying soft tissue collapses into the bone defects, creating contours that make it difficult or impossible to make esthetic functional prostheses. The height and width of residual ridge allow placement of pantie that appears to emerge from the ridge and mimics the appearance of the neighboring teeth. Such residual ridge contour may lead to uncsthctic open gingival surfaces (“black triangle”), food impaction and percolation of saliva during speech. There arc high incidences of residual ridge deformity following anterior tooth loss; a majority of these are class 3 defects. This clinical report describes, the soft-tissue ridge augmentation to correct alveolar ridge defect combined with fixed prosthodontics to achieve maximum esthetics and health.

Abstract

Patients with restricted mouth opening after maxillcctomy procedure, often complain of difficulty in placement and removal of the dental prosthesis. Such a problem can be overcome by fabrication of a sectional removable prosthesis. This article presents a fabrication procedure of prosthesis for a patient with restricted mouth opening after partial maxillectomy, where the two sections, namely, the hollow bulb and the conventional complete denture, were retained to each other by incorporation of magnets and magnet keepers in both the sections.

Reattachment of a Vertical Subgingival Crown Root Fracture -A Case Report

[Year:2012] [Month:January-June] [Volume:2] [Number:1] [Pages:5] [Pages No:50 - 54]

GET ACCESS    DOI: 10.5005/jsd-2-1-50  |  Restricted |  How to cite  | 

Abstract

Functional, csthetic and biologic restoration of a fractured tooth is often a clinical challenge. In particular, the treatment and prognosis of teeth with crown-root fracture are dictated solely by the extent of the fracture line. Among many conventional therapies, re attachment of the fractured segment by adhesives is now considered as a viable treatment option to quickly obtain both morphology and esthetics. The treatment strategy for complicated subgingival crown-root fracture includes periodontal surgical exposure, endodontic management and finally the fragment reattachment. This paper reports the management of a complicated crown-root fracture in a young adult, by reattaching the fractured fragments using adhesive technology.
