Selected AbstractsOral hygiene of elderly people in long-term care institutions , a cross-sectional studyGERODONTOLOGY, Issue 4 2006Luc M. De Visschere Objective:, The aim of this cross-sectional study was to assess the level of oral hygiene in elderly people living in long-term care institutions and to investigate the relationship between institutional and individual characteristics, and the observed oral cleanliness. Materials and methods:, Clinical outcome variables, denture plaque and dental plaque were gathered from 359 older people (14%) living in 19 nursing homes. Additional data were collected by a questionnaire filled out by all health care workers employed in the nursing homes. Results:, Only 128 (36%) residents had teeth present in one or both dental arches. About half of the residents (47%) wore complete dentures. The mean dental plaque score was 2.17 (maximum possible score = 3) and the mean denture plaque score was 2.13 (maximum possible score = 4). Significantly more plaque was observed on the mucosal surface of the denture with a mean plaque score of 2.33 vs. 1.93 on the buccal surface (p < 0.001). In the multiple analyses only the degree of dependency on an individual level was found to be significantly correlated with the outcome dental plaque (odds ratio: 3.09) and only the management of the institution with denture plaque (odds ratio: 0.43). Conclusion:, Oral hygiene was poor, both for dentures and remaining teeth in residents in long-term care institutions and only the degree of dependency of the residents and the management of the institutions was associated with the presence of dental plaque and denture plaque respectively.

KOYAMA summary, The aim of this study was to investigate the correlation between the masticatory function and the maxillary defect configuration, size, and remaining teeth in post-maxillectomy patients restored with an obturator prosthesis. Fifty consecutive post-maxillectomy patients (mean age 67·0) participated in this study. The subjects consisted of 26 dentate and 24 edentulous patients. Data were collected from the patients' clinical records, diagnostic casts, and a questionnaire on masticatory function to evaluate the defect configuration, size, and the masticatory function scores associated with wearing obturator prostheses. The defect size was evaluated by the ratio of defect area to the horizontal impression area. The defect configuration was assessed according to Aramany's classification and separated into unilateral and bilateral defects. The multiple regression analysis and the Mann,Whitney U -test (P < 0·05) were used to assess statistical significance. The Spearman's correlation coefficient by rank test was also used to detect correlation. The following conclusions were made: (i) The presence of teeth in the maxillary dentition and the different type of the defect configuration had significant correlation with the masticatory function score (r = 0·616). (ii) The masticatory function scores of the subjects differed significantly with the presence of teeth in the maxillary dentition and the different types of defect configurations (P = 0·005, P = 0·002, respectively). (iii) There was significant correlation between the masticatory function score and the size of the defect area in the edentulous group (r = ,0·648, P = 0·001). The presence of teeth, the size and configuration of the defect influenced the masticatory function of post-maxillectomy patients with obturator prostheses. [source] Outcome of Oral Implant Treatment in Partially Edentulous Jaws Followed 20 Years in Clinical FunctionCLINICAL IMPLANT DENTISTRY AND RELATED RESEARCH, Issue 4 2006Odont Dr/PhD, Ulf Lekholm DDS ABSTRACT Background:, Most long-term follow-up studies of implants in partially edentulous jaws present their outcomes as mean values of implant survival and follow-up time, and few address the fate of the remaining teeth. Purpose:, The aim of this study was to investigate the results of oral implant treatment in partially edentulous jaws after 20 years, and simultaneously to assess what happens to teeth present at the time of implant placement. Materials and Methods:, Seventeen partially edentulous patients, of 27 originally treated individuals, were retrospectively reviewed after receiving implants from 1983 to 1985. The parameters studied were implant survival, prosthesis stability, marginal bone loss at teeth and implants, treatment complications, need for dental treatment, and patient's satisfaction with the outcome. Results:, The cumulative survival rate was 91%, when all 27 patients were assessed, that is, including the 10 dropouts. Of the 69 inserted and followed implants (Brånemark system®; Nobel Biocare AB, Göteborg, Sweden), six failed (8.7%) during the 20-year period, four during the first decade, and the remaining two during the second. A majority (n=4) of the losses were due to implant fractures, two after 8 years, and two after 17 years. In all, 10 of the original fixed bridges being followed (n=24) remained in function during the entire investigation period, whereas 12 were exchanged for new constructions after an average of 7 years. The mean marginal bone loss at teeth was 0.7 mm, and at implants it was 1.0 mm. The major complication observed during the second decade was veneer material fractures, which occurred 14 times in six patients. Component loosening and abutment- and bridge-locking screw fractures were the second most common problems seen, indicating material/component fatigue. Most patients were satisfied with their treatment and many mentioned that they did not think of the constructions as anything but a part of their own body. Conclusion:, Over the decades, treatment of partially edentulous jaws with turned titanium implants seems to function well and to provide patients with good support for fixed short-span bridge constructions. [source] Attrition, occlusion, (dys)function, and intervention: a systematic reviewCLINICAL ORAL IMPLANTS RESEARCH, Issue 2007Arie Van 't Spijker Abstract Objectives: Attrition and occlusal factors and masticatory function or dysfunction are thought to be related. This study aims to systematically review the literature on this topic with the emphasis to find evidence for occlusion-based treatment protocols for attrition. Materials and methods: Literature was searched using PubMed (1980 to 2/2006) and the Cochrane Library of Clinical Trials with the keywords ,tooth' and ,wear'. Five steps were followed. Exclusion was based on the following: (1) reviews, case-reports, studies on non-human tooth material, and studies not published in English and (2) historical or forensic studies. Included were (3) in vivo studies. Next, studies on (4) occlusal factors, function or dysfunction [temporomandibular disorders (TMD), bruxism], or intervention, and (5) attrition were included. Two investigators independently assessed the abstracts; measure of agreement was calculated using Cohen's ,; disagreement was resolved by discussion. Full-text articles were obtained and correlation between outcomes on occlusal factors, (dys)function, treatment, and attrition were retrieved. References in the papers included in the final analysis were cross-matched with the original list of references to add references that met the inclusion criteria. Results: The search procedure revealed 1289 references on tooth wear. The numbers of included studies after each step were (1) 345 (,=0.8), (2) 287 (,=0.87), (3) 174 (,=0.99), (4) 81 (,=0.71), and (5) 27 (,=0.68). Hand searches through the reference lists revealed six additional papers to be included. Analysis of the 33 included papers failed to find sound evidence for recommending a certain occlusion-based treatment protocol above another in the management of attrition. Conclusion: Some studies reported correlations between attrition and anterior spatial relationships. No studies were found suggesting that absent posterior support necessarily leads to increased attrition, though one study found that fewer number of teeth resulted in higher tooth wear index (on the remaining teeth). Attrition seems to be co-existent with self-reported bruxism. Reports on attrition and TMD signs and symptoms provide little understanding of the relationship between the two. [source] Bonding of fractured permanent central incisor crown following radiographic localization of the tooth fragment in the lower lip: a case reportDENTAL TRAUMATOLOGY, Issue 5 2010Gabriela Ferrari Da Silva Schwengber The trauma also resulted in a cut on his mentum. Radiographic examination revealed the fractured tooth fragment embedded in the lower lip. The fractured tooth, with incomplete root formation, was treated endodontically and received a temporary restoration. After 15 days, the temporary restoration was removed and the fractured tooth fragment was etched with 37% phosphoric acid. A bonding system was then applied to the etched-fractured tooth surface without polymerization. The same bonding procedure was carried out on the tooth fragment. A layer of flowable resin composite was applied to the fragment, which was positioned on the remaining tooth. The resin composite was then polymerized, finished, and polished. [source] Longitudinal study on the relationship between serum albumin and periodontal diseaseJOURNAL OF CLINICAL PERIODONTOLOGY, Issue 4 2008Masanori Iwasaki Abstract Aim: The purpose of this study was to evaluate the relationship between periodontal disease and the general health status in community-dwelling elderly using the serum albumin concentration as a criterion index of the severity of underlying disease and nutrition. Material and Methods: Six hundred subjects aged 70 years underwent a baseline examination. Dental examinations were carried out at baseline and once a year for 4 years. Periodontal conditions were estimated for subjects with at least one remaining tooth. Clinical attachment levels at six sites of all teeth present were measured. A change in loss of attachment of 3 mm or greater in 1 year at each site was defined as periodontal disease progression. Data were analysed in subjects for whom data were available for 4 years. Results: Serum albumin concentration at baseline ranged from 3.4 to 5.0 g/dl with a mean of 4.3±0.2. When the analysis was stratified by smoking status, we found that serum albumin concentration had a significant effect on periodontal disease progression among non-smokers (standardized regression coefficient=,0.16; p=0.017), using multiple regression analysis. Conclusions: The findings of the present study suggest that serum albumin concentration is a significant risk predictor of periodontal disease progression among elderly non-smokers.
