Selected AbstractsPeriapical status and quality of endodontic treatment in an adult Irish populationINTERNATIONAL ENDODONTIC JOURNAL, Issue 2 2005J. J. Loftus Abstract Aim, To determine the prevalence of apical periodontitis and the quality of root fillings in an adult Irish population using a retrospective analysis of orthopantomograms (OPGs). Methodology, A systematic sample of clinical records and OPGs of 302 adult patients attending the Dublin Dental Hospital, Ireland, were screened by two examiners to determine the quality of root canal treatment and the prevalence of apical periodontitis. The operators who carried out the treatment were unknown. Two examiners inspected OPGs after inter-examiner correlation. European Society of Endodontology (ESE) guidelines were used to determine adequacy of root treatment. Results, Of the 7427 teeth examined 2% had root fillings. Apical periodontitis was evident in 1.6% of all nonroot filled teeth whilst 33.1% of the subjects had at least one tooth with apical periodontitis. Of the root filled teeth, 25% had apical periodontitis and 52.6% were considered technically inadequate by ESE guidelines. There was a statistically significant (P < 0.05) negative correlation between the quality of the root fillings and the prevalence of apical periodontitis. Posterior root filled teeth (premolars and molars) had a greater prevalence of apical periodontitis than anterior root filled teeth. Conclusions, The technical quality of root fillings in an adult Irish population was poor and was consistent with a high prevalence of apical periodontitis. [source] Morbidity following dental treatment of children under intubation general anaesthesia in a day-stay unitINTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 1 2004S. Atan Summary. Objectives., To determine which variables were best related to the overall morbidity of a child undergoing dental general anaesthetic (GA) and then to use these variables to determine those factors that might influence the extent and severity of morbidity experienced by healthy children following dental GA. Sample and methods., Data were collected on anxiety, pain and morbidity, GA procedure and dental procedure from 121 children attending a day stay GA unit for dental treatment. Patients were interviewed preoperatively, postoperatively before discharge then four further times over the next 148 h. Data were analysed using multivariate regression. Results., Thirty-one per cent of subjects had restorative work, 60% had at least one tooth extracted, 54% had a surgical procedure. Use of local analgesia reduced postoperative pain whilst an increase in the number of surgical procedures increased it. Increase in anaesthetic time was related to increased odds of feeling sleepy and nauseous, females were more likely to complain of sleepiness or weakness. Feelings of dizziness were increased if the patient was given local analgesia during the procedure. Conclusions., Pain following dental GA was the most prevalent and long lasting symptom of postoperative morbidity in this study. Reductions in operating time and improvement in pain control have the potential to reduce reported morbidity following dental GA. [source] Tooth loss during maintenance following periodontal treatment in a periodontal practice in NorwayJOURNAL OF CLINICAL PERIODONTOLOGY, Issue 7 2004Øystein Fardal Abstract Background: Periodontal therapy coupled with careful maintenance has been shown to be effective in maintaining periodontal health; however, a small number of teeth are still lost because of progressive periodontitis. Aim: To investigate factors associated with tooth loss due to periodontal reasons during maintenance following periodontal treatment in patients in a Norwegian specialist periodontal practice. The study also examined how initial prognosis related to actual outcome as measured by periodontal tooth loss. Methods: Hundred consecutive patients (68 females, 32 males) who had comprehensive periodontal treatment and attended for 9.8 (SD: 0.7), range: 9,11 years of maintenance care, were studied. All teeth classified as being lost due to periodontal disease over the period were identified. Results: Only 36 (1.5%) of the 2436 teeth present at baseline were subsequently lost due to periodontal disease. There were 26 patients who lost at least one tooth. Logistic regression analysis showed that tooth loss was significantly related to male gender (p=0.049; adjusted odds ratio: 2.8; confidence interval (c.i.): 1.0,8.1), older age, i.e.>60 years (p=0.012; adjusted odds ratio: 4.0; c.i.: 1.3,12.0) and smoking (p=0.019; adjusted odds ratio: 4.2; c.i.: 1.4,13.8). The majority 27 (75%) of the teeth lost due to periodontal disease had been assigned an uncertain, poor or hopeless initial prognosis; however, nine teeth (25%) lost had been assigned a good prognosis at baseline. The prognosis for 202 teeth was judged to have worsened over the period of the study. Conclusion: Compliance with maintenance following periodontal treatment was associated with very low levels of tooth loss in a referral practice in rural Norway. Male gender, older age (>60 years) and smoking were predictors of tooth loss due to progressive periodontitis. [source] Immediate and early non-occlusal loading of Straumann implants with a chemically modified surface (SLActive) in the posterior mandible and maxilla: interim results from a prospective multicenter randomized-controlled studyCLINICAL ORAL IMPLANTS RESEARCH, Issue 5 2008Axel Zöllner Abstract Objective: Immediate and early loading of dental implants can simplify treatment and increase overall patient satisfaction. The purpose of this 3-year prospective randomized-controlled multicenter study was to assess the differences in survival rates and bone level changes between immediately and early-loaded implants with a new chemically modified surface (SLActive). This investigation shows interim results obtained after 5 months. Material and methods: Patients ,18 years of age missing at least one tooth in the posterior maxilla or mandible were enrolled in the study. Following implant placement, patients received a temporary restoration either on the day of surgery (immediate loading) or 28,34 days after surgery (early loading); restorations consisted of single crowns or two to four unit fixed dental prostheses. Permanent restorations were placed 20,23 weeks following surgery. The primary efficacy variable was change in bone level (assessed by standardized radiographs) from baseline to 5 months; secondary variables included implant survival and success rates. Results: A total of 266 patients were enrolled (118 males and 148 females), and a total of 383 implants were placed (197 and 186 in the immediate and early loading groups, respectively). Mean patient age was 46.3±12.8 years. After 5 months, implant survival rates were 98% in the immediate group and 97% in the early group. Mean bone level change from baseline was 0.81±0.89 mm in the immediate group and 0.56±0.73 mm in the early group (P<0.05). Statistical analysis revealed a significant center effect (P<0.0001) and a significant treatment × center interaction (P=0.008). Conclusions: The results suggested that Straumann implants with an SLActive can be used predictably in time-critical (early or immediate) loading treatment protocols when appropriate patient selection criteria are observed. The mean bone level changes observed from baseline to 5 months (0.56 and 0.81 mm) corresponded to physiological observations from other studies, i.e., were not clinically significant. The presence of a significant center effect and treatment × center interaction indicated that the differences in bone level changes between the two groups were center dependent. [source] | ||||||||||
