Root Canal Therapy (root + canal_therapy)
Selected AbstractsIMPLANT OR ROOT CANAL THERAPY: AN ENDODONTIST'S VIEWJOURNAL OF ESTHETIC AND RESTORATIVE DENTISTRY, Issue 3 2005Martin Trope DMD [source] Quality of root canal fillings performed by undergraduate dental students on single-rooted teeth,EUROPEAN JOURNAL OF DENTAL EDUCATION, Issue 2 2006C. D. Lynch Introduction:, Root canal therapy is an accepted and successful form of tooth conservation. Educational guidelines require dental schools to ensure that their graduates are competent on graduation at performing root canal therapy. The aim of this investigation was to assess the technical quality of root canal fillings placed by undergraduate students in single-rooted teeth. Materials and methods:, A total of 100 radiographs of root canal fillings placed by undergraduate students in single-rooted teeth were examined under even illumination in a darkened room using ×2 magnification. These were graded as ,adequate', where the root canal filling was within 2 mm of the radiographic apex, ,under-filled', where the root canal filling was >2 mm from the radiographic apex, and ,over-filled', where the root canal filling was extruded beyond the radiographic apex. The presence of voids, fractured instruments, and root perforations were also noted. Results:, All teeth were obturated with gutta-percha and sealer (Roth Cement), using a cold lateral condensation technique. Of 100 teeth, 10% (n = 10) had voids. Of the remainder, 70% (n = 63) were judged to be ,acceptable', 21% (n = 19) were ,under-filled', and 9% (n = 8) were ,over-filled'. There was no evidence of fractured instruments or root perforations in any root filling examined. Conclusions:, The quality of root canal fillings placed in single-rooted teeth by undergraduate dental students at the University Dental School and Hospital, Cork was acceptable (63% of root fillings placed in single rooted teeth were graded as ,adequate'). The probable reasons for this are multi-factorial, but may be linked to the amount of pre-clinical and clinical teaching in endodontics at the University Dental School and Hospital, Cork. It should be remembered that factors other than radiographic quality/evidence must be considered when determining the outcome of root canal therapy. [source] Surgical repositioning of a traumatically intruded permanent incisor in a patient with rheumatic fever: case reportDENTAL TRAUMATOLOGY, Issue 1 2009Rosana Sales Dias However, it is one of the most severe types of dentoalveolar trauma. By definition, intrusive luxation consists of the axial displacement of the tooth into the alveolar bone, accompanied by comminution or fracture of the alveolar bone. Here we report the treatment management of a traumatically intruded immature permanent central incisor by surgical repositioning undertaken in a 10-year-old child with rheumatic fever 10 days after sustaining a severe dentoalveolar trauma. The intraoral examination showed the complete intrusion of the permanent maxillary right central incisor and the radiographic examination revealed incomplete root formation. Prophylactic antibiotic therapy was prescribed and the intruded tooth was surgically repositioned and endodontically treated thereafter. The postoperative course was uneventful, with both clinically and radiographically sound conditions of the repositioned tooth up to 3 years and 2 months of follow-up. These outcomes suggest that surgical repositioning combined with proper antibiotic prophylaxis and adequate root canal therapy may be an effective treatment option in cases of severe intrusive luxations of permanent teeth with systemic involvement. [source] Anatomy of an overfill: a reflection on the processENDODONTIC TOPICS, Issue 1 2007ALAN H. GLUSKIN The design and implementation of shaping, cleaning and sealing objectives in root canal therapy are fraught with real and potential pitfalls when the anatomic complexity of the space and technical considerations for its instrumentation, disinfection and obturation are contemplated. This review will focus on the genesis of results that lead to endodontic overfills. We will look at how the literature defines overfill and overextension; attempt to address the consensus opinion on the definition of working length; and determine the effects of shaping geometry on overfill as well as the biological impact of obturation materials that go beyond the root canal space. In addition, this manuscript will highlight evidence for the prevention of overfills as well as focus on the local factors that affect repair and healing. [source] Epidemiologic issues in studies of association between apical periodontitis and systemic healthENDODONTIC TOPICS, Issue 1 2004Daniel J. Caplan Perhaps the most exciting issue currently facing the dental research community centers around a hypothesized connection between chronic inflammatory oral infections, most notably periodontal disease, and the development of adverse systemic health conditions. To date, inflammation of endodontic origin (i.e., apical periodontitis (AP)) has not been extensively studied in this regard despite being a commonly found sequel to bacterial infection of the dental pulp space. Although numerous differences exist between chronic inflammatory disease of periodontal and endodontic origins, there are some notable similarities, primarily that: (1) both often are associated with Gram-negative anaerobic bacteria, and (2) elevated cytokine levels may be released systemically from acute and chronic manifestations of both disease processes. This article provides a brief review of several important concepts concerning adverse general health outcomes as they relate to periodontal disease, summarizes recent epidemiologic studies of AP and root canal therapy, and reviews some general issues involved in the conduct of epidemiologic studies as well as how these issues apply to investigations that address potential links between endodontic inflammatory disease and adverse systemic health outcomes.

[source] Propofol intravenous conscious sedation for anxious children in a specialist paediatric dentistry unitINTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 1 2004M. T. Hosey Summary. Objectives., To report on both the use and dosage of propofol, as a new intravenous (IV) conscious sedative agent, for anxious children referred to a specialist paediatric dentistry service. Setting., Paediatric Dentistry Unit, Glasgow Dental Hospital and School. Sample., Thirty-four children, 25 females and 9 males, mean age 12 years 10 months, with a mean weight of 54·6 kg (range 30,110 kg). Methods., Report from 34 patients receiving intravenous sedation for the first time in respect of weight dose and amount of treatment completed. Results., Thirty-two children successfully accepted operative dental care on their first visit, they received a mean total dose of 146·25 mg of propofol (range 10 mg to 356 mg); in relation to body weight, the mean was 2·5 mg/kg (range 0·2,5·4 mg/kg). The treatment that they received included fissure sealants, amalgam and adhesive restorations, root canal therapy and single and multiple extractions. Their sedation and recovery were uneventful. Conclusions., Sub-anaesthetic doses of propofol used for IV conscious sedation infusion facilitated operative dental treatment in anxious children. [source] The management of severe dental phobia in an adolescent boy: a case reportINTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 4 2000J. Levitt Dental fear is a widespread problem that represents one of the major barriers to dental care. This report describes a case study of a 12-year-old boy who presented with dental phobia characterized as ,fear of catastrophe', ,generalized dental fear' and ,fear of specific stimuli'. The referral came from his general dental practitioner who had been unable to carry out even the simplest dental procedure on him. The patient required prevention, conservation and root canal therapy. The case illustrates the use of physical strategies, including muscle relaxation and relaxation breathing; practice strategies, including graded exposure and cognitive strategies, combined with individual control methods and inhalation sedation to successfully complete the dental treatment plan. [source] Postoperative pain and associated factors in adolescent patients undergoing two-visit root canal therapyAUSTRALIAN ENDODONTIC JOURNAL, Issue 2 2009Patrícia De Andrade Risso dds Abstract This prospective study investigated the frequency and intensity of postoperative pain and identified associated factors in adolescents undergoing two-visit root canal therapy. Sixty-four patients aged 11 to 18 years old presenting with molars with pulp necrosis were assigned consecutively to two visits (plus an interappointment dressing using calcium-hydroxide paste). Pain intensity was recorded on a visual analogue scale (VAS) of 0,5. Data were analysed using multivariate logistic regression. The frequency of postoperative pain was 32.8% (21/64), with intensities of VAS 1 and VAS 2 in 81%, VAS 3 in 14.3% and VAS 4 in 4.7% of the 21 cases in which it was experienced. Spontaneous preoperative pain (odds ratio (OR) = 6.60; 95% confidence interval (CI) = 1.61,26.97; P = 0.009) and absence of apical perodontitis (OR = 5.65; 95% CI = 1.34,23.87; P = 0.01) were associated with postoperative pain. The frequency of postoperative pain was high, but the intensity, in general, was low, including flare-ups. The presence of spontaneous preoperative pain and absence of apical periodontitis increase the probability of suffering from postoperative pain. [source] Conservative treatment of patients with periapical lesions associated with extraoral sinus tractsAUSTRALIAN ENDODONTIC JOURNAL, Issue 3 2007Janir Alves Soares phd Abstract This paper describes the clinical courses of three cases with extra-oral sinus tract formation, from diagnosis and treatment to short-term follow-up and evaluation. All teeth involved had periradicular radiolucent areas noted on radiographic examination and extra-oral sinus tracts appearing on the chin with exudation and unpleasant aesthetic appearance. The adopted treatment protocol included treating the sinus tract surface simultaneously with the root canal therapy. After root canal shaping using 5.25% sodium hypochlorite solution, calcium hydroxide-based pastes associated with different vehicles were inserted into the root canal for 4 months, and were changed monthly. All the sinus tracts healed in 7 to 10 days. The apical lesions were completely repaired in a maximum period of 24 months. The treatment adopted provided a complete healing of the periapical lesions in a short follow-up period. Surgical repair of the cutaneous sinus tract was therefore unnecessary. [source] | ||||||||||
