Objectives: To assess the 3-year cumulative survival rate of atraumatic restorative treatment (ART) and conventional resin composite restorations (CRT) placed in persons with disability. Materials and methods: Patients referred for restorative care to the Haemophilia Foundation special care service were treated by one of two specialists. Patients and/or caregivers were provided with written and verbal information regarding treatment options and selected the alternative they preferred. Treatment was provided as selected unless this option proved clinically unfeasible when an alternative technique was proposed. The treatment protocols were ART (hand instruments/high-viscosity glass-ionomer) in the clinic or CRT (rotary instrumentation/resin composite) in the clinic or under general anaesthesia (GA). After 6, 12, 24 and 36 months, two independent, trained and calibrated examiners evaluated restoration survival using established ART codes. The proportional hazard model with frailty corrections gave survival estimates over 3 years. Results: Sixty-six patients (13.6 ± 7.8 years) with 16 different disability profiles participated. CRT in the clinic proved feasible for five patients (13%), and 14 patients received CRT under GA (21%). ART was used for 47 patients (71.2%). Altogether, 298 dentine carious lesions were restored in primary and permanent teeth (182 ART; 116 CRT). The 3-year cumulative survival rates and jackknife standard errors for the 182 ART and 116 CRT restorations were 94.8 ± 2.1 and 82.8 ± 5.3%, respectively ( p = 0.01). Conclusions: The 3-year follow-up results confirm that ART is an effective treatment protocol. Clinical relevance: Patients with disability, many of whom have difficulty coping with CRT, may benefit from the ART approach. [ABSTRACT FROM AUTHOR]

Objectives: The aims of this study were to compare 2-year cumulative survival rates of amalgam and atraumatic restorative treatment (ART) restorations in primary molars and to investigate the determinants of the survival rate of restorations. Materials and methods: A controlled clinical trial using a parallel group design was carried out on 258 children aged 6-7 years old, allocated to two treatment groups: conventional restorative treatment using amalgam and ART using high-viscosity glass ionomer. A total of 364 amalgam restorations and 386 ART restorations were placed by three pedodontists in 126 and 158 children, respectively, and were evaluated after 0.5, 1, and 2 years. Restorations were placed in vital primary molars with neither pain nor signs of pulp involvement. The survival analysis was conducted using the proportional hazard rate regression model with frailty correction. Results: The 2-year cumulative survival rates for all amalgam (77.3 %) and ART (73.5 %) restorations were not statistically significantly different, but there was an effect of 'type of surface' (single/multiple) and 'cavity filling time' on the survival rates. Both amalgam and ART single-surface restorations had higher survival rates than multiple-surface restorations of the same material. Secondary caries was responsible for 36 and 38 % of failures in amalgam and ART restorations, respectively. Mean time for restoring all type of cavities with amalgam and ART restorations was 13.6 and 13.7 min, respectively. Conclusions: Amalgam and ART restorations presented similar survival rates over a 2-year period for all, single-surface, and multiple-surface restorations. Clinical relevance: In the cause of finding alternatives to amalgam, ART restorations using high-viscosity glass ionomer might be a suitable option for managing cavitated dentine carious lesions in vital primary molars.

Objectives: The objective of this study was to assess the effectiveness of a supervised implementation of the 'Oral health care Guideline for Older people in Long-term care Institutions' (OGOLI) in The Netherlands. Materials and methods: A sample of 12 care homes in the Netherlands was allocated randomly to an intervention or control group. While the residents in the control group received oral health care as before, the intervention consisted of a supervised implementation of the OGOLI. Results: At baseline, the overall random sample comprised 342 residents, 52 % in the intervention group and 48 % in the control group. At 6 months, significant differences were observed between the intervention and the control group for mean dental as well as denture plaque, with a beneficial effect for the intervention group. The multilevel mixed-model analyses conducted with the plaque scores at 6 months as outcome variables showed that the reduction by the intervention was only significant for denture plaque. Conclusions: Supervised implementation of the OGOLI was more effective than non-supervised implementation in terms of reducing mean plaque scores at 6 months. However, the multilevel mixed-model analysis could not exclusively explain the reduction of mean dental plaque scores by the intervention. Clinical relevance: A supervised implementation of an oral health care guideline improves oral health of care home residents. [ABSTRACT FROM AUTHOR]

The aim of the present study was to assess the caries experience of children aged 6 to 7 years old in a socially deprived suburban area of Brazil's Federal District, using the ICDAS II system and to investigate determinants of dental caries. The survey was carried out in six public schools by three calibrated examiners, on a sample of 835 children. ICDAS II codes had to be converted into dmf/DMF components at surface and tooth levels, resulting in unfamiliar caries variables, to enable some meaningful reporting of the findings. The prevalence of dental caries, including enamel and dentinal carious lesions, in primary teeth was 95.6% and in permanent teeth it was 63.7%. Mean values of dmf-t (enamel and dentinal lesions), dmf-t (dentine lesions), DMF-T and DMF-T indices were 6.9 ± 3.8, 3.2 ± 3.4, 1.7 ± 1.6 and 0.2 ± 0.5, respectively. Enamel carious lesions predominated in the dmf-t/s and DMF-T/S indices. Seven-year-old children had statistically significantly more enamel and dentine carious lesions in permanent teeth than 6-year-old children had. Using ICDAS II, the prevalence of dental caries in both dentitions was very high. In both dentitions, the decay component predominated, with hardly any restorations or extractions observed. The new ICDAS II system leads to overvaluation of the seriousness of dental caries experience and made reporting of outcomes cumbersome. Guidelines on analysing data and reporting results should be agreed upon before this system can be used in epidemiological surveys globally. [ABSTRACT FROM AUTHOR]

Mw. M. Mijan will defend her PhD thesis on 15th September 2017. Whilst reviewing her work in preparation to the event, we discovered a few irregularities that prompted a recheck of the database and ditto analyses. These activities have lead to a few textual changes in the publication. [ABSTRACT FROM AUTHOR]
