Glass Ionomer Restoration (glass + ionomer_restoration)
Selected AbstractsConnective tissue graft plus resin-modified glass ionomer restoration for the treatment of gingival recession associated with non-carious cervical lesion: a randomized-controlled clinical trialJOURNAL OF CLINICAL PERIODONTOLOGY, Issue 9 2009Mauro Pedrine Santamaria Abstract Background: The aim of this clinical study was to evaluate the treatment of gingival recession, associated with non-carious cervical lesions by a connective tissue graft (CTG) alone, or in combination with a resin-modified glass ionomer restoration (CTG+R). Materials and Methods: Forty patients presenting Miller Class I buccal gingival recessions, associated with non-carious cervical lesions, were selected. The defects were randomly assigned to receive either CTG or CTG+R. Bleeding on probing (BOP), probing depth (PD), relative gingival recession (RGR), clinical attachment level (CAL) and cervical lesion height (CLH) coverage were measured at baseline and 45 days, and 2, 3 and 6 months after treatment. Results: Both groups showed statistically significant gains in CAL and soft tissue coverage. The differences between groups were not statistically significant in BOP, PD, RGR and CAL, after 6 months. The percentages of CLH covered were 74.88 ± 8.66% for CTG and 70.76 ± 9.81% for CTG+R (p>0.05). The estimated root coverage was 91.91 ± 17.76% for CTG and 88.64 ± 11.9% for CTG+R (p>0.05). Conclusion: Within the limits of the present study, it can be concluded that both procedures provide comparable soft tissue coverage. The presence of the glass ionomer restoration may not prevent the root coverage achieved by CTG.

Material and Methods: Sixteen patients with bilateral Miller Class I buccal gingival recessions, associated with non-carious cervical lesions, were selected. The defects received either CAF or CAF+R. Bleeding on probing (BOP), probing depth (PD), relative gingival recession (RGR), clinical attachment level (CAL) and cervical lesion height (CLH) coverage were measured at the baseline and 6, 12 and 24 months after the treatment. Results: Both groups showed statistically significant gains in CAL and soft tissue coverage. The differences between groups were not statistically significant in BOP, PD, RGR and CAL, after 2 years. The percentages of CLH covered were 51.57 ± 17.2% for CAF+R and 53.87 ± 12.6% for CAF (p>0.05). The estimated root coverage was 80.37 ± 25.44% for CAF+R and 83.46 ± 20.79% for CAF (p>0.05). Conclusion: Within the limits of the present study, it can be concluded that both procedures provide acceptable soft tissue coverage after 2 years, with no significant differences between the two approaches. [source] Influence of local anaesthesia on the quality of class II glass ionomer restorationsINTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 4 2007NANDA VAN DE HOEF Objective., To investigate the influence of local anaesthesia on the quality of class II glass ionomer restorations with discomfort as cofactor. Material and methods., The study population consisted of 6- to 7-year-old schoolchildren in Paramaribo and its environs. To be included, each child needed to have a proximally situated cavity in a primary molar that was accessible to hand instruments and where no pulp exposure was expected. They were randomly divided into four treatment groups: conventional method with and without local anaesthesia and atraumatic restorative treatment method (ART) with and without local anaesthesia. The restoration quality was scored using the evaluation criteria for ART restorations (successful if restoration is correct or has a minor defect and fails if defects are larger than 0.5 mm, if secondary caries is observed, if the restoration is fractured, partly or totally lost or if the pulp is involved) at 6 and 30 months after treatment. The extent of discomfort was registered by assessing the behaviour (modified Venham score) and observing the heart rate during treatment. Results., For this study 153 children were treated with hand instruments (ART) and 146 children with rotary instruments (conventional method). A total of 198 restorations were evaluated during follow-up periods. There were no significant differences in patient discomfort between the ART and the conventional group and between the anaesthesia and the non-anaesthesia group. The conventional restorations demonstrated significantly higher success rates than ART restorations after 6 (P = 0.001) and 30 months (P = 0.032). There were no significant differences in success rate between the anaesthesia and the non-anaesthesia group. Conclusion., Local anaesthesia has no influence on discomfort during treatment. Furthermore, discomfort during treatment does not affect the success rate of restorations. [source] The post-amalgam era: a selection of materials and their longevity in the primary and young permanent dentitionsINTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 3 2003H. Forss Summary. Objectives. During the last decade there has been a rapid change in the selection of dental restorative materials as the use of amalgam has decreased. The aim of this study was to obtain information on children's restorative dental care in Finland and to analyse the longevity of failed restorations. Design. A random sample of public dental health care centres was drawn from the registers and the dentists working there were asked to record information for each restoration they placed during a three-day period. The survey data comprised a total of 2186 restorations in patients younger than 17 years. Results. Of the children in need of restorative treatment, only a few had previous amalgam restorations. Primary caries was the main reason for restorative treatment in both primary and permanent dentitions (80% and 83%, respectively). In primary teeth, the most common restorative material was resin-modified glass ionomer cement (57·4%), whereas in permanent teeth, composite resin dominated (58·7%). Amalgam was not used at all in the primary dentition and in only 0·6% of permanent teeth. Eighteen per cent of treatments in primary and 12% in permanent teeth were replacements of previous fillings. The mean age of failed glass ionomer restorations was 2·8 years (n = 101) in the primary dentition, and 3·5 years (n = 54) in the permanent dentition. Conclusions. Until better restorative materials are developed, more attention should be paid to the prevention of dental caries as well as to the proper handling of alternative materials. [source] | ||||||||||
