[Ab] Resumo:Data sourcesRelevant databases were searched for the review such as the Cochrane Oral Health Group Trials Register, Medline, EMBASE, clinical trials.gov, WHO International Clinical Trials Registry Platform.Study selectionRandomised controlled trials comparing adhesively bonded versus non-bonded class I and II amalgam restorations in permanent molars and premolars.Data extraction and synthesisTwo reviewers independently screened papers and extracted data.ResultsOne trial with 31 patients who received 113 restorations was included. At two years, 50 out of 53 restorations in the non-bonded group survived and 55 of 60 restorations survived with five unaccounted for at follow-up. Post insertion sensitivity was not statistically significant at baseline and for the two-year follow-up. No fractures or differences in the marginal adaptation were reported.ConclusionsThere is no evidence either to claim or to refute a difference in survival between bonded and non-bonded amalgam restorations. In view of the lack of evidence on the additional benefit of adhesively bonding amalgam in comparison with non-bonded amalgam, it is important that clinicians be mindful of the additional costs that may be incurred.

[Ab] Resumo:The aim of this study was to carry out a representative survey on the implementation of and experience with repairs of single-tooth restorations among dentists in the Canton of Zurich, Switzerland. An anonymous questionnaire was sent to all 1,411 dentists registered in the Canton of Zurich; 38.9% of the delivered questionnaires were returned and 35.3% could be evaluated. The statistical analysis comprised Kendall’s rank correlation coefficient (tau), Wilcoxon signed-rank tests, and Kruskal-Wallis tests. The level of significance was set at p≤0.05. Repair restorations are frequently made (composite: 98.5%, ceramic: 88.9%, crowns: 86.5%, metal: 54.6%, amalgam: 51.5%). Main indications for repairs were the partial loss of an existing restoration or of the adjacent dental hard substance, while restoration failures due to secondary caries were repaired to a lesser extent. The decision to repair is largely dependent on the size of the defect (90%), the size of the original restoration (63%), and the material of the failed restoration (84%). Repair restorations are most frequently made with composite following adequate conditioning of the repair surface. A majority of the dentists rate the lifespan of repair restorations as reduced in comparison with newly made restorations. In summary, repairs of defective single-tooth restorations are frequently performed by dentists in the Canton of Zurich, Switzerland, and constitute a well-established treatment procedure.

[Ti] Título:Relationship between mercury in kidney, blood, and urine in environmentally exposed individuals, and implications for biomonitoring.

[Ab] Resumo:BACKGROUND: Individuals without occupational exposure are exposed to mercury (Hg) from diet and dental amalgam. The kidney is a critical organ, but there is limited information regarding the relationship between Hg in kidney (K-Hg), urine (U-Hg), blood (B-Hg), and plasma (P-Hg). OBJECTIVES: The aim was to determine the relationship between K-Hg, U-Hg, B-Hg, and P-Hg among environmentally exposed individuals, estimate the biological half-time of K-Hg, and provide information useful for biomonitoring of Hg. METHODS: Kidney cortex biopsies and urine and blood samples were collected from 109 living kidney donors. Total Hg concentrations were determined and the relationships between K-Hg, U-Hg, P-Hg, and B-Hg were investigated in regression models. The half-time of K-Hg was estimated from the elimination constant. RESULTS: There were strong associations between K-Hg and all measures of U-Hg and P-Hg (r =0.65-0.84, p<0.001), while the association with B-Hg was weaker (r =0.29, p=0.002). Mean ratios between K-Hg (in µg/g) and U-Hg/24h (in µg) and B-Hg (in µg/L) were 0.22 and 0.19 respectively. Estimates of the biological half-time varied between 30 and 92days, with significantly slower elimination in women. Adjusting overnight urine samples for dilution using urinary creatinine resulted in less bias in relation to K-Hg or U-Hg/24h, compared with other adjustment techniques. CONCLUSIONS: The relationship between K-Hg and U-Hg is approximately linear. K-Hg can be estimated using U-Hg and gender. Women have longer half-time of Hg in kidney compared to men. Adjusting overnight urine samples for creatinine concentration resulted in less bias.

[Ab] Resumo:Allergen-triggered lichenoid oral mucosa lesions may occur both in oral lichen planus (OLP) and oral lichenoid lesions (OLL). Clinically, OLP and OLL are difficult to distinguish from each other. An OLP should be checked by histological examination. Therefore all patients with OLP should be included into a close control interval due to the the potential malignant transformation, whereas in the literature a higher risk of malignancy is attributed to OLL in comparison with OLP. Based on a clinical case, it is demonstrated that an interdisciplinary approach in allergy and mucous diagnosis is necessary to verify the correaltion between a contact allergy to amalgam and the lichenoid mucosal lesions. The subsequent treatment exemplifies the steps of dental therapies with multiple contact allergies to dental materials.

[Ab] Resumo:OBJECTIVES: The aim of this study was to investigate the influence of artifacts produced by different restorative materials on the detection of approximal caries in cone-beam computed tomography (CBCT) scans with and without the application of an artifact-reduction (AR) option. STUDY DESIGN: Ninety-eight noncavitated premolar and molar teeth were placed with approximal contacts consisting of 2 sound or carious teeth and 1 mesial-occlusal-distal restored tooth with resin-modified glass-ionomer cement (RMGIC), amalgam, composite, ceramic-based composite (CBC), or computer-aided design-computer-aided manufacturing (CAD-CAM) zirconia materials in between. The teeth were scanned with a CBCT system with and without the AR option. Images were evaluated by 2 observers. The teeth were histologically evaluated, and sensitivity, specificity, and areas under the receiver operating characteristic (ROC) curve were calculated according to the appropriate threshold. RESULTS: Specificity and sensitivity values for contact surfaces ranged from 0-48.39 and 82.93-98.40, respectively. The AR option affected (P < .05) approximal caries detection of the amalgam, composite, CAD-CAM, and CBC groups in contact surfaces and composite and RMGIC groups in noncontact surfaces. CONCLUSION: Artifacts produced by different restorative materials could affect approximal caries detection in CBCT scans. Use of the AR option with CBCT scans increases the accuracy of approximal caries detection.

[Ti] Título:Long term changes in health complaints after removal of amalgam restorations.

[Ab] Resumo:OBJECTIVE: Concerns over adverse effects of mercury released from dental amalgam sometimes lead patients to request removal of their amalgam restorations. Several studies report improvement of subjective health after removal of amalgam restorations, but the mechanisms are unclear. The aim of this paper is to present data on long term changes in intensity of health complaints after amalgam removal in a group of patients with health complaints self-attributed to dental amalgam. Data from the five years follow-up in a clinical trial are presented and related to potential determinants of change. MATERIALS AND METHODS: Patients previously referred to a specialty unit for health complaints attributed to amalgam restorations were included in the study. The 20 participants who were allocated to the treatment group had all amalgam restorations removed and replaced with other dental restorative materials. Intensity of health complaints was calculated from questionnaire data and personality variables were measured by MMPI-2. RESULTS: At the follow-up five years after the amalgam removal was completed, intensity of general health complaints was significantly reduced (p=.001), but the symptom load was still high. The reduction was significantly correlated with concentration of mercury in urine at pre-treatment. There were no significant correlations with personality variables. CONCLUSIONS: Removal of amalgam restorations was followed by a long term reduction of general health complaints, which was associated with mercury concentration in urine before amalgam removal. Additional studies are needed to confirm the potential mechanisms for the observed reduction.

[Ab] Resumo:Mercury (Hg) is toxic and hazardous metal that causes natural disasters in the earth's crust. Exposure to Hg occurs via various routes; like oral (fish), inhalation, dental amalgams, and skin from cosmetics. In this review, we have discussed the sources of Hg and its potential for causing toxicity in humans. In addition, we also review its bio-chemical cycling in the environment; its systemic, immunotoxic, genotoxic/carcinogenic, and teratogenic health effects; and the dietary influences; as well as the important considerations in risk assessment and management of Hg poisoning have been discussed in detail. Many harmful outcomes have been reported, which will provide more awareness.
