Glass ionomer cements and their role in the restoration of non-carious cervical lesions

Journal of Applied Oral Science — Fri, 20 Nov 2009 13:59:45 +0100

Glass ionomer based materials are clinically popular in several areas of restorative dentistry, but restoration of cervical lesions has proven particularly successful. Various etiologies, conformations, locations and structural characteristics make non-carious cervical lesions more challenging to adhesive restorative procedures and marginal seal in the long run. Due to their characteristics, glass ionomer cements (GICs) have precise indication for these cases. Moreover, the use of a GIC base underneath composite resin, the so-called "sandwich" or mixed technique, allows associating the good characteristics of composite resins and GICs, and has been considered quite useful in the restoration of non-carious cervical defects. The aim of this paper is to critically review the literature and di...

Is the tongue position influenced by the palatal vault dimensions?

Journal of Oral Rehabilitation — Wed, 18 Nov 2009 00:00:00 +0100

Summary The influence of the palatal vault dimensions on tongue position is here studied through evaluation of the in-mouth air cavity (IMAC) volume when the mandible is in maximal intercuspal position. A sample of 35 women (mean age 21·2 ± 1·0) and 15 men (mean age 22·1 ± 0·9) was selected. The sagittal cross-section area of the IMAC, which is modulated by the tongue position, was measured on lateral cephalograms. Dental casts were used to measure the palatal vault volume, which was defined by the occlusal plane, the hard palate and the posterior face of the second molars. Palatal vault volume allowed deduction of the IMAC volume through a rule of three procedure relating volume to area ratios. No IMAC could be calculated from cephalograms of 10 subjects who had the tongue stuck to ...

Widespread pain symptoms and psychological distress in southern Chinese with orofacial pain

Journal of Oral Rehabilitation — Tue, 17 Nov 2009 00:00:00 +0100

Summary The study investigated the experience of widespread pain (WP) symptoms and psychological distress in southern Chinese with orofacial pain (OFP). A community-based, cross-sectional case[ndash]control study involving people aged 35[ndash]70 registered with the Hospital Authority/University of Hong Kong Family Medicine Clinic served as the sampling frame. People with recent OFP symptoms and a group without OFP took part. Standard questions were asked about OFP conditions in the previous month. Psychological status was evaluated through depression, and non-specific physical symptoms (NPS) scores were measured with depression and somatization sub-scales of the Symptom Checklist-90. Widespread pain was determined using body outline drawings to identify painful sites prior to a standard c...

Removal of intracanal smear layer by doxycycline: SEM analysis

Australian Endodontic Journal — Tue, 17 Nov 2009 00:00:00 +0100

The aim of this study was to verify the efficacy of doxycycline used alone or in association with sodium hypochlorite on smear layer removal. The canals of extracted human teeth were instrumented using a stepback technique. At the end of preparation, they were irrigated with doxycycline (Group 1), ethylenediaminetetraacetic acid + sodium hypochlorite (Group 2), doxycycline + sodium hypochlorite (Group 3) and water (Group 4). The dentinal wall of the cervical, middle and apical thirds was graded according to the amount of remaining debris and smear layer. The results were analysed using the Kruskal[ndash]Wallis test (P < 0.05). In Groups 2 and 4, the dentine was completely free and covered with smear layer, respectively. The results from the cervical and middle thirds of Group 3 were worse ...

Emotional stress and orthodontic tooth movement: effects on apical root resorption, tooth movement, and dental tissue expression of interleukin-1 alpha and calcitonin gene-related peptide immunoreactive nerve fibres in rats.

European Journal of Orthodontics — Mon, 16 Nov 2009 00:00:00 +0100

Authors: Vandevska-Radunovic V, Murison R The aim of the study was to investigate the effect of emotional stress on apical root resorption (ARR) and tooth displacement during orthodontic tooth movement in rats. A further area of interest was to evaluate if the expression of interleukin-1 alpha (IL-1alpha) as well as the density and distribution of peptidergic nerve fibres immunoreactive to calcitonin gene-related peptide (CGRP) in the periodontal ligament (PDL) are associated with possible stress-induced changes in root resorption and tooth movement. A total of 52 male Wistar rats, aged 6 weeks, were divided in three experimental and one control group (n = 4). Group 1 had orthodontic tooth movement and received foot shocks (OTMS; n = 16), group 2 had orthodontic tooth movement but rece...

Which Evidence has an Impact on Dentists' Willingness to Change Their Behavior?

The Journal of Evidence-Based Dental Practice — Sat, 14 Nov 2009 14:00:56 +0100

There is some literature on how to find the best evidence for clinical practice but little is known about which evidence clinicians actually seek when they look for scientific support in changing behavior. The aim of this study was to explore which evidence has an impact on dentists' willingness to change their behavior by investigating the requirements for seeking and understanding new knowledge, as well as perceived barriers or motives for doing this.A postal questionnaire was analyzed according to demographic information, access to and use of a personal computer, postgraduate education activity, knowledge about evidence-based medicine and scientific terms, and seeking and grasping new and actual knowledge from 177 dentists. Fifteen of these dentists formed 3 focus groups that were inter...

Promoting Evidenced-based Dentistry through “The Dental Practice-Based Research Network”

The Journal of Evidence-Based Dental Practice — Sat, 14 Nov 2009 14:00:56 +0100

This article focuses on dental practice-based research networks (PBRNs) as one of the solutions to the oftentimes slow and inefficient process of translating research evidence into clinical practice. This article identifies two major issues that are faced when setting up a dental practice-based research network. Using a dental practice-based research network that the author is involved with as an example, this article then discusses what is involved in undertaking a research project in your office. Also discussed are the types of projects being done in this new setting and how this author believes these studies will be one of the bridges toward developing evidenced based dentistry in private practice.

Implementation of Clinical Practice Guidelines in Dental Settings

The Journal of Evidence-Based Dental Practice — Sat, 14 Nov 2009 14:00:55 +0100

Conclusion: Generally, dentists in the United Kingdom were more familiar with the current expert recommendations on AP than dentists in Iran; however, dentists in both countries tended to overprescribe. This could contribute to the problem of antimicrobial resistance. Educational initiatives aimed at implementing updated recommendations and continuous assessment of dental practice might reverse this trend. (Source: The Journal of Evidence-Based Dental Practice)

Translating Evidence-Based Decision Making into Practice: Appraising and Applying the Evidence

The Journal of Evidence-Based Dental Practice — Sat, 14 Nov 2009 14:00:55 +0100

This is the second of 2 articles that focus on strategies to integrate an evidence-based decision-making (EBDM) approach into your practice. The previous article provided an overview of EBDM concepts and identified strategies for finding evidence to answer clinical questions, the first 2 steps in the evidence-based process. The next steps are to determine the credibility and usefulness of the evidence and to apply the evidence to patient care. The purpose of this article is to discuss those steps by reviewing the critical appraisal criteria used to assess the methodological quality of a study. A case scenario will be used to demonstrate how appraising the evidence helps to answer questions and how to translate the evidence into everyday practice. Characteristics of an evidence-based practi...

JEBDP Requirements, Standards, and Procedures for Awarding Dental Continuing Education Credit for Analysis and Review of Manuscripts and Original Articles

The Journal of Evidence-Based Dental Practice — Sat, 14 Nov 2009 14:00:55 +0100

The Journal of Evidence-Based Dental Practice (JEBDP) is among the first dental journals in the United States and the first dental journal published by Elsevier to give continuing education credit to its reviewers. Peer reviewing is a newer form of continuing medical education (CME). JEBDP follows several medical journals awarding CME to reviewers, including the Journal of the American Medical Association (JAMA), New England Journal of Medicine (NEJM), Academic Emergency Medicine, Annals of Internal Medicine, Gastroenterology, and others. The straightforward rationale for this program is that by conducting a thorough analysis and review of a primary journal article or submitted manuscript, the reviewer engages in a clear and powerful learning activity. In all cases, JEBDP reviewers must ac...

The habits have harmful unbalanced pressures to be born by the immature highly malleable alveolar ridges. Sucking behaviors have long been recognized to affect occlusion and dental arch characteristics. As early as 1870s, Campbell and Chandler recognized that prolonged finger or thumb sucking habits had deleterious effects on certain occlusal traits including anterior open bite, increased over jet and class II canine and molar relationships.

Clinical manifestations of Ellis-van Creveld syndrome

Journal of Indian Society of Pedodontics and Preventive Dentistry — Sat, 14 Nov 2009 13:59:42 +0100

Vinay C, Reddy R Sudhakara, Uloopi K S, Sekhar R ChandraJournal of Indian Society of Pedodontics and Preventive Dentistry 2009 27(4):256-259Ellis-van Creveld syndrome (EVC) is a chondro-ectodermal dysplasia characterized by short ribs, polydactyly, growth retardation and ectodermal and heart defects. It is a rare disease complex and very few cases have been reported in dental literature. This condition is inherited as an autosomal recessive trait with variable expression. The present case report describes EVC in a 7-year-old girl, with all the tetrad of cardinal features. We found a rare dental aberration in form; appearance of single conical roots in primary molars. The management of children with EVC is multidisciplinary, with consideration for the high incidence of cardiac defects in th...

Management of temporomandibular disorder associated with bruxism

Journal of Indian Society of Pedodontics and Preventive Dentistry — Sat, 14 Nov 2009 13:59:42 +0100

Bedi S, Sharma AJournal of Indian Society of Pedodontics and Preventive Dentistry 2009 27(4):253-255Bruxism is the non-functional clenching or grinding of the teeth that may occur during sleep or, less commonly in the daytime in 5-20% of adults and about 30% of 56 year old children. Although research on bruxism is extensive, its etiology remains debatable. There is some literature to suggest that bruxism is correlated with temporomandibular disorders (TMDs) and malocclusion. The aim of this article is to present the course of this condition in a case of bruxism coupled with TMD with special emphasis on the importance of accurate diagnosis of maxillofacial pain. We also report an association between supernumerary teeth and TMDs that has not been reported earlier in the literat...

Cleidocranial dysplasia: A family report

Journal of Indian Society of Pedodontics and Preventive Dentistry — Sat, 14 Nov 2009 13:59:42 +0100

Chelvan H Thamizh, Malathi N, Kailasam Vignesh, Ponnudurai AJournal of Indian Society of Pedodontics and Preventive Dentistry 2009 27(4):249-252A 10-year-old girl presented with a chief complaint of many unerupted teeth. Complete clinical and radiological examination of this patient confirmed the diagnosis of cleidocranial dysplasia (CCD). Her father also presented similar features with a lesser clinical severity. CCD is an autosomal-dominant heritable skeletal disease caused by heterozygous mutations in the osteoblast-specific transcription factor RUNX2 gene. Failure of tooth eruption is probably mainly due to this mutated gene in CCD patients. Interdisciplinary treatment approach is obligatory for rehabilitation of these patients. In confirmed cases, genetic counseling for family plannin...

Why the carioprotective potential of luting cements crucial?

Journal of Indian Society of Pedodontics and Preventive Dentistry — Sat, 14 Nov 2009 13:59:42 +0100

In this study, 100 molars were taken, which were banded and stored in artificial saliva for 1 month after which the teeth were debanded. An area of 2 x 2 mm was spared and the teeth were coated with nail varnish. The coated teeth were dipped in artificial caries solution in one month followed by 1-day immersion in methylene blue dye, after which the samples were sectioned through the window. The depth of dye penetration was measured and the results were statistically analyzed. Minimum dye penetration was observed with glass ionomer, which could be due to the fluoride release from the cement, whereas the control group showed the maximum, probably due to direct contact with the artificial caries solution.

Factors influencing ridge alterations following immediate implant placement into extraction sockets

Clinical Oral Implants Research — Sat, 14 Nov 2009 00:00:00 +0100

To identify factors that may influence ridge alterations occurring at the buccal aspect of the extraction site following immediate implant placement. In 93 subjects, single-tooth implants were placed immediately into extraction sockets in the maxilla (tooth locations 15[ndash]25). A series of measurements describing the extraction site were made immediately after implant installation and at re-entry, 16 weeks later. The implant sites were stratified according to four factors: (i) implant location (anterior/posterior), (ii) cause of tooth extraction (periodontitis/non-periodontitis), (iii) thickness of the buccal bone walls ([le]1/>1 mm) and (iv) the dimension of the horizontal buccal gap ([le]1/>1 mm). (i) The location where the implant was placed (anterior/posterior) as well as (ii) the t...
