Oral Health Practices and Oral Cancer Knowledge Attitudes and Behaviors among College Students

[Year:2010] [Month:October-December] [Volume:1] [Number:3] [Pages:8] [Pages No:141 - 148]

   DOI: 10.5005/jp-journals-10015-1030  |  Open Access |  How to cite  | 

Abstract

Objective

This study examines the knowledge about the risk factors and symptoms of oral cancer, attitudes toward oral cancer and associated behaviors of college students using constructs of the Health Belief Model and the predictors of oral screening of college students.

Participants

College of Health Science students (N = 300) at a State university located in the Northeastern US were surveyed.

Methods

A 25-item questionnaire was administered during the Fall 2009 semester, which measured knowledge and behaviors related to oral cancer risk factors.

Results

Participants perceived their oral health to be good (63.6%), were unaware of dental diseases (95.5%), visited a dentist (60.5%), had a dental visit (62.2%) within the last 6 months, and scheduled one (66.3%) in the next 6 months. There was a significant correlation between the behavior of use of tobacco and the perceived susceptibility to oral cancer (t = 8.10, p < 0.05) and perceived severity (t = 2.22, p < 0.05) if a person got oral cancer. There were no significant variables which predicted oral cancer screening. Having a dental visit best predicted the scheduling of a future dental visit.

Conclusions

Findings from this study may further assist in future health education and dental screening programs for this population group across the US.

Comparison of Various Root Planing Instruments: Hand and Ultrasonic—Standard Smooth and Diamond Coated: An in vivo Study

[Year:2010] [Month:October-December] [Volume:1] [Number:3] [Pages:9] [Pages No:149 - 157]

   DOI: 10.5005/jp-journals-10015-1031  |  Open Access |  How to cite  | 

Abstract

Aim and objective

This study was conducted to evaluate and compare the effectiveness of various root planing instruments, namely the curette, standard smooth ultrasonic tip and diamond coated ultrasonic tip under conditions of nonsurgical root debridement.

Materials and methods

A total of 20 incisors from 14 patients, with a pocket depth of 5 to 10 mm, indicated for extraction were selected for the study. Teeth selected were randomly assigned to one of the two groups, experimental group A and experimental group B. The proximal surfaces of teeth in experimental group A was instrumented with either Gracey curette or standard smooth ultrasonic tip and in experimental group B with either Gracey curette or diamond coated ultrasonic tip, randomly. Teeth were extracted without injuring the experimental area. The surface area under treatment was photographed at 10X and the percentage of residual calculus was evaluated. Teeth were processed for viewing under scanning electron microscope. Photomicrographs were graded for degree of cleanliness, Remaining Calculus Index (RCI) and Roughness and Loss of Tooth Substance Index (RLTSI) by an independent examiner.

Results

Percentage of residual calculus as evaluated using stereomicroscope did not show any statistical significance within the groups and among all the three instruments. Scanning electron microscopic assessment for the degree of cleanliness showed better cleanliness for curette compared to standard smooth ultrasonic tip. Remaining calculus was significantly higher for standard smooth ultrasonic tip compared to curette. Diamond coated ultrasonic tip showed greater roughness and loss of tooth substance.

Conclusion

Within the limits of this in vivo study, diamond coated ultrasonic tip removed a greater amount of root surface and created a rougher surface compared to the curette and standard smooth ultrasonic tip. The amount of root surface removed with diamond coated ultrasonic inserts suggests that they should be used with caution.

Orthodontic Force Distribution: A Three-dimensional Finite Element Analysis

[Year:2010] [Month:October-December] [Volume:1] [Number:3] [Pages:4] [Pages No:159 - 162]

   DOI: 10.5005/jp-journals-10015-1032  |  Open Access |  How to cite  | 

Abstract

This study was designed to investigate the stress pattern and magnitude in periodontal ligament of maxillary central incisor for tipping and bodily tooth movement using finite element method and to determine the optimal orthodontic force required for bodily tooth movements compared to previous clinical, histologic, and laboratory studies. The three-dimensional FEM consisting of 27000 isoparametric elements of maxillary central incisor was constructed based on the average anatomic morphology given by Wheeler. Principal stresses in PDL were determined for tipping and bodily tooth movement. On application of optimal forces for tipping and bodily tooth movement, stress value seen in PDL was less, however the distribution of stress pattern coincided with the previous studies.

Fibroblast Proliferation due to Exposure to a Platelet Concentrate: An in vitro Study

[Year:2010] [Month:October-December] [Volume:1] [Number:3] [Pages:4] [Pages No:163 - 166]

   DOI: 10.5005/jp-journals-10015-1033  |  Open Access |  How to cite  | 

Abstract

Introduction

The major cellular events in the tissue repair are mitogenesis, migration and metabolism. The proteins responsible for coordination of these events are called “growth factors”. The activated platelets at the wound margins release several growth factors, such as PDGF, TGF-β and EGF, etc., and plasma exudates also provide an important source of TGF-β factors.

Materials and methods

Periodontal ligament fibroblast obtained from third molar impaction surgery, periodontal ligaments were cultured under standard conditions and spread on 96 well tissue culture plates. Platelet concentrate was obtained after centrifugation of 350-400 ml of blood at 1000 and 5000 rpm. 15 μl of platelet concentrate was added to each well. The proliferation rate of test and control group was determined by Redox indicator (Alamar blue® assay). The number of cells were counted by neu bar counting chamber after 24, 48 and 72 hours.

Results

The proliferation activity of cells was considerably higher in the platelet concentrate group (test group) than the control group. The difference was highly significant upto 72 hours after addition of platelet concentrates (Mann-Whitney U test p < 0.001).

Conclusion

A cellular effect of the platelet concentrate is clearly discernible. It was concluded that the use of platelet concentrate is an effective modality of regeneration.

Clinical Evaluation of Type I Bovine Collagen in the Treatment of Localized Gingival Recession

[Year:2010] [Month:October-December] [Volume:1] [Number:3] [Pages:7] [Pages No:167 - 173]

   DOI: 10.5005/jp-journals-10015-1034  |  Open Access |  How to cite  | 

Abstract

Background

Over the years, coronally advanced flap and the use of guided tissue regeneration have been among the more successful techniques in treating gingival recession. The present study compared the relative efficacies of these two techniques in treating gingival recession.

Methods

Twelve patients presenting with localized identical anterior recessions were taken up in a split mouth design for the study. One site was randomly assigned to be treated with coronally advanced flap supported by membrane while the other was treated with coronally advanced flap alone. Changes in clinical parameters, such as recession width, recession depth, surface area of the recession defect, width of keratinized tissue, gingival status, probing pocket depth and clinical attachment level were measured at baseline and at 3 and 6 months postoperatively.

Results

In the 10 patients that were followed up, both treatments resulted in a significant gain in root coverage amounting to a mean gain of 66.49% in the membrane group and 65.56% in the CAF group. The differences in root coverage and the clinical attachment level gains between the groups were not significant. However, significant gain in the width of keratinized tissue was seen in the membrane group after treatment.

Conclusion

This study suggests that coronally advanced flap procedure provides a predictable, simple and convenient technique in the treatment of localized class I gingival recession. Combining this technique with the placement of a bioabsorbable membrane does not seem to improve the results. The addition of a membrane, however, increases the width of keratinized tissue.

Natural Tooth Pontic using Fiber-reinforced Composite for Immediate Tooth Replacement

[Year:2010] [Month:October-December] [Volume:1] [Number:3] [Pages:5] [Pages No:175 - 179]

   DOI: 10.5005/jp-journals-10015-1035  |  Open Access |  How to cite  | 

Abstract

For patients who require removal of anterior teeth due to periodontal problems there are a multitude of treatment considerations. Using the natural tooth as a pontic offers the benefits of being the right size, shape and color. This paper describes the immediate replacement of an anterior tooth using a preimpregnated fiber-reinforced composite with the natural tooth as the pontic. The abutment teeth can be preserved with minimal or no preparation, thus keeping the technique reversible, and can be completed at the chair side thereby avoiding laboratory costs. It can be used as an interim measure or as a definitive prosthesis.

   DOI: 10.5005/jp-journals-10015-1036  |  Open Access |  How to cite  | 

Abstract

All-ceramic restorations have been used for long as restorative material in dentistry. However, the recent advances in both the material and technology of all-ceramic have made them a more viable treatment option. Several practitioners hesitate in giving this option to patient for fear of failure. This article describes all the failures of all-ceramic material and how to prevent them. In particular, the article highlights various errors that clinicians make while preparing tooth to receive all-ceramic restorations and how to rectify them.

Diagnostic Perils in Jaw Pain

[Year:2010] [Month:October-December] [Volume:1] [Number:3] [Pages:6] [Pages No:187 - 192]

   DOI: 10.5005/jp-journals-10015-1037  |  Open Access |  How to cite  | 

Abstract

Chronic pain in the orofacial region is a common complaint faced by clinicians. It is important for the dentists to have a thorough knowledge of various causes of jaw pain. Most common type reported is toothache. Since toothache is so common, it is important to determine if pain is from odontogenic or nonodontogenic origin. The need for careful diagnosis before undertaking any invasive treatment is the key to prevent misdiagnosis and mismanagement in patients with chronic orofacial pain. Emphasis in this article is on the differential diagnosis of jaw pain originating from muscular, neuropathic, cardiac, sinus and psychogenic origin.

Ramon's Syndrome: A Rare Entity

[Year:2010] [Month:October-December] [Volume:1] [Number:3] [Pages:6] [Pages No:199 - 204]

   DOI: 10.5005/jp-journals-10015-1039  |  Open Access |  How to cite  | 

Abstract

Introduction

Ramon et al in 1967 described a condition, which included mental retardation, fibrous dysplasia of the maxilla and stunted growth. De Pino et al described a Brazilian family of four who had the same features as that of Ramon's syndrome in association with juvenile arthritis. Cherubism was first described in 1933 by Jones as ‘familial multilocular cystic lesion of the jaws’, a rare benign fibroosseous disease of the jaws, which is transmitted as an autosomal dominant trait. Affected children usually present before five years of age with painless progressive swelling of the cheeks, frequently associated with dental malformations. It progresses until puberty, and shows partial or complete spontaneous involution in adulthood; therefore, management is mostly conservative. The condition was initially characterized as familial, particularly as a form of craniofacial fibrous dysplasia. The children affected with cherubism do not usually show mental or physical deformities, but when cherubism is associated with other syndromes like Noonan-like syndrome, Ramon syndrome, and Fragile X syndrome, mental and physical deformities may be seen.

Case Report

This is a case report of a 12-year-old boy who reported with a massive painless bilateral swelling of the face, which has been increasing since the age of 2 years. The patient had multiple unerupted teeth, gingival hyperplasia, hearing loss and mental retardation. A detailed case report, including the histopathology, radiographic features (extraoral, CT and MDCT), and management of the case will be discussed in detail.

Chronic Odontogenic Sinus Tracts associated with an Impacted Tooth: Report of Two Cases

[Year:2010] [Month:October-December] [Volume:1] [Number:3] [Pages:4] [Pages No:205 - 208]

   DOI: 10.5005/jp-journals-10015-1040  |  Open Access |  How to cite  | 

Abstract

Odontogenic sinus tracts in the face and neck region are relatively uncommon and may present a diagnostic problem. As specific dental symptoms usually are absent in these cases, patients generally visit physician first for the evaluation and treatment because of the absence of dental symptoms. These cutaneous sinus tracts are most commonly located on the chin, cheek or in the submandibular area and rarely in the nasal region. Diagnostic errors can result in multiple surgical excisions and biopsies, long-term antibiotic therapy and even radiation therapy or electrodessication.1 The primary odontogenic disorder that results in such cutaneous lesions is typically a chronic periapical abscess or an impacted tooth or a root piece. We report two cases of extraoral sinus tracts, which were diagnosed as cutaneous sinus tracts of dental origin only after the failure of initial misdirected therapy.

Papillon-Lefevre Syndrome: A Novel Familial Presentation

[Year:2010] [Month:October-December] [Volume:1] [Number:3] [Pages:4] [Pages No:209 - 212]

   DOI: 10.5005/jp-journals-10015-1041  |  Open Access |  How to cite  | 

Abstract

Papillon-Lefevre syndrome (PLS) is a condition characterized by dermatological manifestations and early onset periodontitis. The pathogenesis of PLS is secondary to mutation of the cathepsin C gene. Hence, the manifestations are expressed on the areas of the body covered by epithelium, such as palms, soles, knees and keratinized oral gingiva. Various immune cells, including polymorphonuclear leukocytes, macrophages, and their precursors are also affected leading to functional disability. PLS is an autosomal recessive condition and can occur in siblings born of consanguineous marriages. This report highlights a rare instance of two siblings of a family affected with Papillon-Lefevre syndrome.

The Weak Link in Endodontics: Gutta-Percha—A Need for Change

[Year:2010] [Month:October-December] [Volume:1] [Number:3] [Pages:8] [Pages No:217 - 224]

   DOI: 10.5005/jp-journals-10015-1043  |  Open Access |  How to cite  | 

Abstract

The use of gutta-percha as a standard obturation material over more than 100 years has made little changes in the obturation technique. With the advent of bonding and composite resins as a routine restorative material, the concept of bonded obturation has come into picture. The Resilon-Epiphany system has brought about a paradigm shift in the conventional obturation technique. This article explores the possibilities of the material as a replacement for gutta-percha. It also discusses the currently available forms of the material and a clinical case depicting its use.

The Influence of Infectious Diseases on Dentistry

[Year:2010] [Month:October-December] [Volume:1] [Number:3] [Pages:7] [Pages No:225 - 231]

   DOI: 10.5005/jp-journals-10015-1044  |  Open Access |  How to cite  | 

Abstract

Dentistry, predominantly a surgical field with frequent exposure to blood and body fluids, is a high-risk occupation with respect to occupationally acquiring infectious diseases. On the same note, patients are also at risk of being infected, if adequate infection control measures are not strictly followed. Traditionally, based on the routes of disease transmission, we can categorize diseases that are bloodborne, airborne and also through fomites. Within these traditional categories also fall the new and emerging diseases that have had serious public health consequences of morbidity and mortality. As a health care provider, dentists must understand the impact of these diseases, and strictly implement practical disease control measures during provision of dental care and reduce the spread within the clinical arena. Common diseases of public health concern that need to be addressed are bloodborne diseases, such as hepatitis A, E, B, C, D and G, HIV; respiratory diseases such as tuberculosis, influenza, severe acute respiratory syndrome (SARS), AH1N1 influenza and immunizable childhood diseases. Apart from infection control measures, we must implement public health policy measures, such as immunization of current and prospective health care personnel (students in the dental profession) against immunizable diseases, utilize disease screening measures, postexposure disease control measures and utilize standard and additional precautions, the latter as required in certain instances.
