Rubber dam usage for endodontic treatment: a review

INTERNATIONAL ENDODONTIC JOURNAL, Issue 11 2009
I. A. Ahmad
Abstract Rubber dam has been available to the dental profession for over 140 years. During this time, the use of rubber dam has been perfected, universally taught and recommended by professional organizations. Unfortunately, its consistent use has been rejected by many in the profession. The literature suggests that rubber dam is not used routinely by dental practitioners for root canal treatment. Many unfounded reasons have been cited for its lack of use, including concerns over patient acceptance, time required for application, cost of equipment and materials, insufficient training, difficulty in use and low treatment fees. Failure to use rubber dam has been shown to influence the choice of root canal irrigant, has a negative impact on treatment outcome and places the patient at risk of swallowing or aspirating materials and instruments. Methods to popularize rubber dam amongst general practitioners are discussed. [source]

Attitudes and use of rubber dam by Irish general dental practitioners

INTERNATIONAL ENDODONTIC JOURNAL, Issue 6 2007
C. D. Lynch
Abstract Aim, To investigate the attitudes towards and use of rubber dam by Irish general dental practitioners. Methodology, A pre-piloted questionnaire was distributed amongst a group of 600 dentists randomly selected from the Irish Register of Dentists. Replies from dentists working in specialist practice or the hospital dental service were excluded. Dentists were surveyed in relation to their use of rubber dam during a variety of operative and root canal treatments, as well as their attitudes to the use of rubber dam in dental practice. Results, A total of 300 replies were considered from a total of 324 that were received. Seventy-seven per cent of respondents (n = 231) worked in general dental practice and 23% (n = 69) worked in the Irish Health Board/Community Dental Service. Rubber dam was ,never' used by 77% of respondents (n = 228) when placing amalgam restorations in posterior teeth, 52% (n = 147) when placing composite restorations in posterior teeth, and 59% (n = 177) when placing composite restorations in anterior teeth. Rubber dam was ,never' used by 39% of respondents (n = 114) when performing root canal treatment on anterior teeth; 32% (n = 84) when performing root canal treatment on premolar teeth; and 26% (n = 51) when performing root canal treatment on molar teeth. Fifty-seven per cent (n = 171) considered rubber dam ,cumbersome and difficult to apply', and 41% (n = 123) considered throat pack ,as good a prevention against inhalation of endodontic instruments as rubber dam'. Conclusions, Whilst rubber dam is used more frequently for root canal treatment than operative treatment, its use is limited. This presents quality issues, as well as medico-legal and safety concerns for both the profession and patients. [source]

A cost-effective simulation curriculum for preclinical endodontics

EUROPEAN JOURNAL OF DENTAL EDUCATION, Issue 1 2004
Roberta Pileggi
A challenge in contemporary dental education is to achieve a smooth transition from preclinical teaching environments to patient-care clinics in a cost-effective manner. The preclinical endodontic courses at The University of Texas, Dental Branch at Houston provide a unique learning environment that enables the student to perform endodontic treatment on extracted teeth in a typodont, and be involved in diagnosis and treatment-planning discussions. The specially designed stone typodont used has built-in radiographic capability, and is mounted at each chair in the clinic. During each preclinical session, students are assigned clinical cubicles and proper aseptic protocol is followed. Students are required to wear gloves, masks and eyewear, and place a rubber dam during treatment. Written self-assessment evaluations based upon prescribed criteria are utilised; feedback is given by faculty composed of both full-time endodontists and graduate students who periodically rotate and are calibrated on a regular basis. In the lecture phase, clinical case scenarios are presented to reinforce concepts of diagnosis and emergency care and to help integrate endodontics with other disciplines; a Socratic-like teaching style is established by the faculty facilitator to create an environment for developing critical-thinking and problem-solving skills. The overall feedback from graduating students has been very positive. Advantages of this format are an easier transition to patient management, a more keen interest in specialsation and a perceived increase in levels of confidence. [source]

A study of endodontic treatment carried out in dental practice within the UK

INTERNATIONAL ENDODONTIC JOURNAL, Issue 1 2001
S. M. Jenkins
Abstract Aim The purpose of this study was to gather both qualitative and quantitative information on the nature of root canal treatment carried out by a group of dentists working within the United Kingdom. Methodology A two-part questionnaire was posted to 720 dentists who graduated from the Dental School, Cardiff, Wales, UK. The first part requested basic information regarding age, year of qualification, field of practice, etc. The second part consisted of 15 questions on endodontic practice and root canal treatment. Results The response rate was 41.5%. Two hundred and ninety-nine questionnaires contained useful information. The majority of practitioners did not use rubber dam during root canal treatment. The vast majority (89%) exposed a radiograph with an instrument of known length in situ to gauge the ,working length', a small number relied upon tactile sensation. Most practitioners used local anaesthetic solution as an irrigant during instrumentation of the root canal. A wide variety of instruments were used for root canal treatment; a stepback technique was preferred by almost half the practitioners. Antiseptic solution was preferred as an interappointment dressing. More than half of the respondents used laterally condensed gutta-percha to obturate root canals in anterior teeth but only one-third used the same technique in posterior teeth. Less than half the respondents exposed a radiograph to check the fit of the master point prior to obturation. Two-thirds of practitioners used a zinc oxide based material as their root canal sealer. Three-quarters of the practitioners exposed a post obturation radiograph. Conclusions The results of this study suggest that although some dentists are using the techniques taught during their undergraduate careers, a large percentage now use techniques with no evidence of clinical effectiveness.

Root canal treatment in general practice in Sudan

INTERNATIONAL ENDODONTIC JOURNAL, Issue 4 2000
M. F. Ahmed
Abstract Aim The aim of this study was to evaluate the practice and depth of knowledge of root canal treatment by dental practitioners in Khartoum, the capital city of Sudan, in order to improve the current status of endodontic therapy. Methodology A questionnaire was posted to 55 registered dental practitioners. Completed questionnaires were analysed in term of simple summary statistics. Results A total of fifty-two (95%) practitioners responded. Eighty-five per cent of the respondents indicated that they performed root canal treatment for their patients. Of these, 84% included molars in their activity. Amongst those who carried out root canal treatment, only one practitioner used rubber dam for isolation, whilst the remainder used cotton wool rolls. The majority of respondents (80%) used hydrogen peroxide to irrigate canals during treatment. Three-quarters of practitioners used formocresol as an interappointment medicament. The stepback preparation technique was the method of choice for 98% of respondents. All practitioners used hand instruments to prepare root canals and all used gutta-percha for obturation; three-quarters of them used cold lateral condensation for all or some cases. The average number of radiographs routinely taken for root canal treatment was three. Only 73% used radiographs for measuring the working length. Ninety-five per cent of respondents indicated that they usually completed a root filling in three or more visits. Three-quarters of practitioners restored the teeth permanently immediately after the obturation and one-quarter preferred waiting for 1 or 2 weeks. Conclusions In Sudan, there are no dental practices limited to endodontics and no postgraduate training programmes. This survey shows the importance of establishing higher specialist training or continuing dental education for practitioners to update their knowledge. [source]

A Prospective Ten-Year Clinical Trial of Porcelain Veneers

JOURNAL OF ESTHETIC AND RESTORATIVE DENTISTRY, Issue 2 2006
Article first published online: 25 APR 200
abstract Objective:, The purpose of this prospective clinical study was to evaluate the performance of porcelain veneers after 5 and 10 years of clinical service. Materials and Methods:, A single experienced clinician placed 87 porcelain veneers in 25 patients in 1990 and 1991. The teeth included maxillary central incisors to first premolars. As described in the 5-year report of this study, preparations included a chamfer margin, 0.3 to 0.7 mm labial enamel reduction, and incisal edge coverage. A single laboratory technician fabricated the veneers using feldspathic porcelain on refractory dies. Internal surfaces were etched with 5% hydrofluoric acid and silanated. Teeth were isolated with a rubber dam prior to veneer placement. All veneers were bonded with a light-activated resin cement. Patients were recalled at 5 to 6 years and at 10 years after initial veneer placement. Two evaluators examined each veneer for retention, fractures, color match, surface roughness, marginal adaptation, leakage, recurrent caries, pulp vitality, and patient satisfaction. Marginal adaptation was assessed further using scanning electron microscopy to examine epoxy replicas. Results:, Five years after placement, all 87 veneers remained in place and had "perfect" color match and surface smoothness. Four veneers had fractures, but only one of those required repair. Ninety-nine percent of the veneers had clinically acceptable marginal adaptation, although just 14% of the veneers had "perfect" marginal adaptation at all margins. One had clinically unacceptable staining from leakage. Recurrent caries was present at the proximal margin of two veneers. At the 10-year evaluation, which had a 93% recall rate, color match and surface roughness remained optimal. Thirteen of 22 patients were very satisfied with the esthetic result, whereas 7 complained of minor esthetic problems. The fracture rate increased substantially, to 34% at the 10-year recall. However, only 11% of the fractures were clinically unacceptable. None of the veneers had debonded, but the percentage of veneers with "perfect" marginal adaptation had declined to only 4%. Leakage was now evident around two-thirds of the veneers, and eight restorations had recurrent caries. Conclusion:, Porcelain veneers are a reliable and effective means for conservative esthetic treatment of anterior teeth in the long term. After 10 years of clinical service, esthetic results remained good, patient satisfaction was high, and the retention rate was excellent. The number of irreparable fractures was low. Appropriate preparation design, occlusion, and use of adhesive materials contribute to the ultimate outcome. [source]

Retention of resin-based pit and fissure sealants: a systematic review

COMMUNITY DENTISTRY AND ORAL EPIDEMIOLOGY, Issue 5 2006
Michèle Muller-Bolla
Abstract,,, The aim of the present study was to perform a systematic review on the retention of resin-based sealants (RBSs) according to the material used and the clinical procedure. An electronic search in MEDLINE, EMBASE, Cochrane library and SCOPUS was completed by a hand search in conference proceedings. One hundred and twenty-four studies were identified, 31 of which were included. The retention rate of auto-polymerized and light-cured RBSs did not differ significantly. Light-cured RBSs had a significantly higher retention rate than fluoride-containing light-cured RBSs at 48 months (RR = 0.80, 95% CI: 0.72,0.89) and more. Concerning the clinical procedure, the scarcity of well-conducted studies made judgement difficult, except for the isolation stage. If using a rubber dam did not affect retention of auto-polymerized RBSs, it did for fluoride-containing light-cured RBSs (RR = 2.03, 95% CI: 1.51,2.73). [source]
