RESUMO

OBJECTIVE: Some patients with Down syndrome experience premature edentulism, which can lead to severe alveolar atrophy. This may cause retention problems with purely mucosa-supported dentures and ill-fitting total dentures. The intellectual disability associated with Down syndrome, with an (implied) inadequate ability for compliance, may pose a further challenge to dental treatment. The aim of this case report was to demonstrate that a combined implant-prosthetic denture with bar constructions can, nevertheless, be implemented in elderly Down syndrome patients with limited cooperation ability. METHOD AND MATERIALS: This report is the first to describe the procedure for an implant-supported total prosthetic restoration with bar joint in a 52-year-old edentulous patient with Down syndrome and limited ability to cooperate. Previous dental solutions had severely curtailed the patient's quality of life. By combining various forms of treatment, including behavior management, the course of therapy could be adapted to the patient's cooperation capability. RESULTS: The implant-supported total prosthetic restoration with bar joint was well accepted by the patient. Moreover, the patient's relatives reported that his life quality had improved distinctly (eg, considerable weight-gain, more positive mood). No impairments of the prostheses were observed during the 24-month follow-up period, and both implants remained clinically inconspicuous. CONCLUSION: The lack, or inadequacy, of dental prostheses can impair the life quality of individuals in need of such restorations. Implant-supported dentures in combination with a bar construction improve the retention of prostheses in atrophied jaws. This form of restoration is also proving to be a successful therapy option for elderly persons with Down syndrome.

RESUMO

A 2-day workshop of ORCA and the IADR Cariology Research Group was organized to discuss and reach consensus on definitions of the most commonly used terms in cariology. The aims were to identify and to select the most commonly used terms of dental caries and dental caries management and to define them based on current concepts. Terms related to definition, diagnosis, risk assessment, and monitoring of dental caries were included. The Delphi process was used to establish terms to be considered using the nominal group method favored by consensus. Of 222 terms originally suggested by six cariologists from different countries, a total of 59 terms were reviewed after removing duplicates and unnecessary words. Sixteen experts in cariology took part in the process of reaching consensus about the definitions of the selected caries terms. Decisions were made following thorough "round table" discussions of each term and confirmed by secret electronic voting. Full agreement (100%) was reached on 17 terms, while the definitions of 6 terms were below the agreed 80% threshold of consensus. The suggested terminology is recommended for use in research, in public health, as well as in clinical practice.

RESUMO

Caries is the most prevalent chronic condition worldwide and the association between high-level intake of sugars and dental decay is strong and well established. Interestingly, to combat caries, dental practitioners and public health dentists in many countries have focused mainly on the application of different kinds of fluorides and fissure sealants but not on the reduction of sugar intake. Furthermore, for many years, sugars have not been the focus of dental research activities presented at the annual conferences of the European Organisation for Caries Research (ORCA) and the European Association of Dental Public Health (EADPH). In 2015, following the publication of the new WHO guidelines on the intake of sugars, the boards of ORCA and EADPH agreed to organize a common symposium entitled "Joint ORCA-ADPH Symposium on Sugar: The Oral Health Perspective". This symposium was organized by a scientific committee and took place on July 6, 2016, in association with the 63rd ORCA Congress in Athens, Greece. It included 9 lectures highlighting different aspects of sugar consumption, contribution of sugar to dental caries, measuring sugar consumption, and fighting against sugar on a patient and public health basis. The purpose of this commentary is to give background information about the rationale of the above-mentioned symposium.

RESUMO

Periodontal diseases and dental caries are the most common diseases of humans and the main cause of tooth loss. Both diseases can lead to nutritional compromise and negative impacts upon self-esteem and quality of life. As complex chronic diseases, they share common risk factors, such as a requirement for a pathogenic plaque biofilm, yet they exhibit distinct pathophysiologies. Multiple exposures contribute to their causal pathways, and susceptibility involves risk factors that are inherited (e.g. genetic variants), and those that are acquired (e.g. socio-economic factors, biofilm load or composition, smoking, carbohydrate intake). Identification of these factors is crucial in the prevention of both diseases as well as in their management. AIM: To systematically appraise the scientific literature to identify potential risk factors for caries and periodontal diseases. METHODS: One systematic review (genetic risk factors), one narrative review (role of diet and nutrition) and reference documentation for modifiable acquired risk factors common to both disease groups, formed the basis of the report. RESULTS & CONCLUSIONS: There is moderately strong evidence for a genetic contribution to periodontal diseases and caries susceptibility, with an attributable risk estimated to be up to 50%. The genetics literature for periodontal disease is more substantial than for caries and genes associated with chronic periodontitis are the vitamin D receptor (VDR), Fc gamma receptor IIA (Fc-γRIIA) and Interleukin 10 (IL10) genes. For caries, genes involved in enamel formation (AMELX, AMBN, ENAM, TUFT, MMP20, and KLK4), salivary characteristics (AQP5), immune regulation and dietary preferences had the largest impact. No common genetic variants were found. Fermentable carbohydrates (sugars and starches) were the most relevant common dietary risk factor for both diseases, but associated mechanisms differed. In caries, the fermentation process leads to acid production and the generation of biofilm components such as Glucans. In periodontitis, glycaemia drives oxidative stress and advanced glycation end-products may also trigger a hyper inflammatory state. Micronutrient deficiencies, such as for vitamin C, vitamin D or vitamin B12, may be related to the onset and progression of both diseases. Functional foods or probiotics could be helpful in caries prevention and periodontal disease management, although evidence is limited and biological mechanisms not fully elucidated. Hyposalivation, rheumatoid arthritis, smoking/tobacco use, undiagnosed or sub-optimally controlled diabetes and obesity are common acquired risk factors for both caries and periodontal diseases.

RESUMO

BACKGROUND: A wide range for the prevalence of Molar-Incisor-Hypomineralisation (MIH) has been found in regional studies. AIM: The aim of this study was to determine the prevalence of MIH in Germany and to compare the findings with other studies. DESIGN: In the compulsory dental school examination, the first permanent molars, permanent incisors, and second primary molars were examined according to EAPD criteria in 2395 children (8.1 ± 0.8 years) in four regions in Germany for the presence of MIH. Examinations were performed by five calibrated examiners (κ = 0.9) on clean teeth after toothbrushing. RESULTS: The prevalence of MIH at the four regions differed considerably (4.3-14.6%) with a mean prevalence of 10.1%. The DMFT/dmft was generally low, but children with MIH exhibited statistically significant higher caries values. A total of 12.0% of the children with MIH also had at least one affected primary molar, which resulted in a statistically significant correlation between primary and permanent teeth. Most of the affected teeth had demarcated opacities, but more than half of the affected children showed at least one tooth with severe MIH. CONCLUSIONS: Molar-Incisor-Hypomineralisation is a prevalent finding in German school children. The prevalence varies highly in different regions, and the high rate of severe forms has clinically relevant implications.

RESUMO

BACKGROUND: Dietary fluoride supplements were first introduced to provide systemic fluoride in areas where water fluoridation is not available. Since 1990, the use of fluoride supplements in caries prevention has been re-evaluated in several countries. OBJECTIVES: To evaluate the efficacy of fluoride supplements for preventing dental caries in children. SEARCH METHODS: We searched the Cochrane Oral Health Group's Trials Register (to 12 October 2011), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 3), MEDLINE via OVID (1950 to 12 October 2011), EMBASE via OVID (1980 to 12 October 2011), WHOLIS/PAHO/MEDCARIB/LILACS/BBO via BIREME (1982 to 12 October 2011), and Current Controlled Trials (to 12 October 2011). We handsearched reference lists of articles and contacted selected authors. SELECTION CRITERIA: We included randomised or quasi-randomised controlled trials comparing, with minimum follow-up of 2 years, fluoride supplements (tablets, drops, lozenges) with no fluoride supplement or with other preventive measures such as topical fluorides in children less than 16 years of age at the start. The main outcome was caries increment measured by the change in decayed, missing and filled tooth surfaces (DMFS). DATA COLLECTION AND ANALYSIS: Two review authors, independently and in duplicate, assessed the eligibility of studies for inclusion, and carried out risk of bias assessment and data extraction. In the event of disagreement, we sought consensus and consulted a third review author. We contacted trial authors for missing information. We used the prevented fraction (PF) as a metric for evaluating the efficacy of the intervention. The PF is defined as the mean caries increment in controls minus mean caries increment in the treated group divided by mean caries increment in controls. We conducted random-effects meta-analyses when data could be pooled. We assessed heterogeneity in the results of the studies by examining forest plots and by using formal tests for homogeneity. We recorded adverse effects (fluorosis) when the studies provided relevant data. MAIN RESULTS: We included 11 studies in the review involving 7196 children.In permanent teeth, when fluoride supplements were compared with no fluoride supplement (three studies), the use of fluoride supplements was associated with a 24% (95% confidence interval (CI) 16 to 33%) reduction in decayed, missing and filled surfaces (D(M)FS). The effect of fluoride supplements was unclear on deciduous or primary teeth. In one study, no caries-inhibiting effect was observed on deciduous teeth while in another study, the use of fluoride supplements was associated with a substantial reduction in caries increment.When fluoride supplements were compared with topical fluorides or with other preventive measures, there was no differential effect on permanent or deciduous teeth.The review found limited information on the adverse effects associated with the use of fluoride supplements. AUTHORS' CONCLUSIONS: This review suggests that the use of fluoride supplements is associated with a reduction in caries increment when compared with no fluoride supplement in permanent teeth. The effect of fluoride supplements was unclear on deciduous teeth. When compared with the administration of topical fluorides, no differential effect was observed. We rated 10 trials as being at unclear risk of bias and one at high risk of bias, and therefore the trials provide weak evidence about the efficacy of fluoride supplements.

RESUMO

PURPOSE: To determine the ability of digital sensors (CMOS and CCD sensors) and D and F-speed films to detect cavitated and non-cavitated enamel caries lesions at different exposure conditions compared to a gold standard. METHODS: 100 extracted human molars and premolars were selected and mounted in a block between two neighboring teeth. Sensors or films were exposed with voltages of 60 or 70 kVp at varying times. Three observers assessed each approximal site independently. Lesion depth was rated according to an anatomical five-point scale (0 = no lesion to 4 = lesion reaching inner half of dentin). Serial sections of resin-embedded teeth were prepared. Gold-standard scores were established by consensus based on histological sectioning. A carious lesion was present at scores of 1 and higher. Statistical evaluation (sensitivity, specificity and receiver-operating curves) was based on caries-free surfaces and those presenting enamel caries (n=116). RESULTS: The ROC curves had "area under the curve" values (Az) from 0.50 (F-speed, 70 kVp, 0.20 seconds) to 0.58 (CCD 60 kVp, 0.08 seconds). The detection percentage of cavitated lesions was generally higher (0-52%, depending on technique and observer) than that of non-cavitated lesions (3-32%). The CMOS sensor showed Az values comparable to the CCD sensors but required higher exposure times. There was no significant difference between 60 and 70 kVp.

RESUMO

OBJECTIVE: To determine the prevalence of dental caries in 12-year-old children in all 16 German Federal States in 2004 as part of a longitudinal observation project. DESIGN: A cross-sectional oral health survey of children 12 years of age was performed in 2004. SUBJECTS: After random selection 43,950 children were examined in schools. METHOD: DMFT and fissure sealants were recorded following WHO criteria. Caries was diagnosed at the caries into dentine threshold (D3) using the visual method without radiography or fibre-optic transillumination. RESULTS: The proportion of children with caries experience was 39.3% throughout Germany. The mean DMFT score was 0.98 and the average Significant Caries Index (SiC) was 2.72. Compared to the results obtained in 2000, caries prevalence and caries experience decreased in this age group. As in 2000, all these specific results showed a wide variation among the different federal states, i.e., mean regional DMFT values between 0.71 and 1.42 were found and the mean number of fissure sealed teeth ranged between 1.9 and 3.4. CONCLUSION: The decrease in caries prevalence observed between 1994 and 2000 continued between 2000 and 2004, although once again considerable inequalities in oral health between the various federal states were observed.

RESUMO

Since 1991, fluoridated salt has been on sale in household-size packages in Germany. Potassium or sodium fluoride is added to iodized salt until the fluoride concentration reaches 250 mg/kg. The use of fluoridated salt to prevent caries is officially recommended by the Deutsche Gesellschaft für Zahn-, Mund- und Kieferheilkunde (DGZMK) and several other associations and groups interested in public health. In the course of the past thirteen years, the market share of fluoridated and iodized domestic salt rose to 63.1% in Germany. However, this positive development must not obscure the fact that fluoridated and iodized salt is still not allowed to be used in restaurant or cafeteria kitchens. This restriction now needs to be revoked in view of the fact that many children, adolescents and adults take their main meals in cafeterias or restaurants. Scientific studies have demonstrated beyond doubt that using fluoridated and iodized salt in cafeteria kitchens poses no problem whatever.

RESUMO

This paper reviews problems associated with urinary collection for the estimation of fluoride exposure and recent findings in this context. After intake of a salted meal at noon, children aged 9 to 14 excreted on average 45 microgF/h. Morning and nocturnal excretions were only 16 microgF/h with the exception of those children who ate bread made with fluoridated salt (25 microF/h). Fluoride excretions in children consuming drinking water with 0.6 to 0.8 ppmF were similar, but the variations within the 24 h period were smaller. When it is not feasible to obtain reliable 24 h urinary collections, fairly precise extrapolations of 24 h excretions can be obtained from three separate collections lasting about 16 hours, which should cover morning, early afternoon and the whole night. Three- to six-year-old children benefitting from optimal fluoride supply through water or milk excreted approximately 0.35 to 0.40 mgF/24 h; this range seems to correspond to an optimal usage of fluorides. Studies on urinary fluoride excretion, like those on total fluoride intake, cannot be carried out on random samples. Due to the necessity of close cooperation of parents and children, such studies were done with "convenience" samples. In westernized countries with now low caries prevalence, intermittent high urinary excretions occur frequently. Possible sources are fluoride intake from concentrated oral care products (fluoride gels, fluoride chewing gums) or from dentifrices (containing 1000 to 1500 ppmF), mineral waters, industrial tea preparation or fluoride tablets (or other supplements). These problems do not affect the amount of fluoride in fingernail clippings which appear to be suitable for the routine monitoring of fluoride exposure.

RESUMO

OBJECTIVES: To determine the longevity of heat-pressed glass ceramic inlays and onlays luted with solely light-curing composite resin. METHODS: The records of patients who had received a ceramic inlay or onlay at the Heidelberg University Department of Conservative Dentistry from 1993 to 2002 were evaluated. The mean observation time and the survival probability of the ceramic inlays and onlays was calculated with the aid of the Kaplan-Meier algorithm. This was done for the total number of all restorations as well as for various subgroups (number of surfaces, tooth type, endodontic condition at the time that the ceramic restoration was incorporated, experience of operator). The log-rank test was used to compare groups and look for significant differences, and p<0.05 was set to be statistically significant. In addition, 95% confidence intervals of the survival probability values were computed. RESULTS: At the time of the last observation, 783 (96.7%) of these restorations were still in place. The mean observation period for all ceramic restorations was 17.3 months (SD 20.2), with an observation interval of between 0 and 116 months. The last loss of a ceramic restoration was observed 45 months after it had been placed, so that the survival probability of all ceramic restorations amounted to p=0.90 (95% confidence interval 0.86-0.94) from this time onward. Factors such as endodontic condition of tooth, type of tooth, position of tooth, extent of restoration, experience of operator or gender of patient had no significant influence on the survival probability of the ceramic restorations. CONCLUSIONS: Heat-pressed glass ceramic inlays and onlays can be used successfully in routine clinical therapy. In addition, this type of inlays and onlays can be placed successfully with solely light-curing composite resin.

RESUMO

OBJECTIVE: To determine the prevalence of dental caries in 12-year-old-children in 11 of the 16 German Federal States over time following the introduction of intensive preventive measures. DESIGN: Cross sectional oral health surveys of children aged 12 years were performed in 1994-1995, 1997 and 2000. SUBJECTS: After random selection 18,459 (1994-1995), 22,908 (1997) and 24,679 (2000) children were examined in schools. METHOD: DMFT and fissure sealants were recorded following WHO criteria. Caries was diagnosed at the caries into dentine (D3) threshold using visual method without radiography or fiber-optic transillumination. RESULTS: The mean DMFT scores for Germany decreased from 2.44 in 1994-1995 to 1.81 in 1997 and 1.24 in 2000. In 1994-1995 31.1% of 12-year-olds had no caries experience (DMFT = 0). The corresponding figures were 42.5% in 1997 and 55.3% in 2000. The average Significant Caries Index (SiC index) dropped from 5.25 in 1994-1995 to 4.29 in 1997 and to 3.30 in 2000. The results in different federal states showed a wide variation in caries prevalence. In the first examination, mean DMFT scores between 2.10 and 3.54 were found, while after the third evaluation corresponding values between 1.03 and 1.95 were observed. In 1997 on average between 0.20 and 2.00 teeth with fissure sealants per child were found, the corresponding values in 2000 were between 2.13 and 2.83. CONCLUSION: The results of our study show considerable inequalities in oral health in the various federal states. Nevertheless, oral health in Germany improved considerably between the years 1994 and 2000.
