Qualitative and Semi-Quantitative Assessment of Processing-Related Surface Contamination of One- and Two-Piece CAD/CAM Abutments before and after Ultrasonic Cleaning. MATERIALS 2020; 13:ma13143225. [PMID: 32698443 PMCID: PMC7412481 DOI: 10.3390/ma13143225] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/11/2020] [Revised: 07/13/2020] [Accepted: 07/14/2020] [Indexed: 11/21/2022]
Abstract
Manufacturing processes of custom implant abutments may contaminate their surfaces with micro wear deposits and generic pollutants. Such particulate debris, if not removed, might be detrimental and provoke inflammatory reactions in peri-implant tissues. Although regulatory guidelines for adequate cleaning, disinfection, or sterilization exist, there does not appear to be a consistent application and data on the amount and extent of such contaminants is lacking. The aim of the present in vitro study was to evaluate the quality and quantity of processing-related surface contamination of computer-aided design/computer-aided manufacturing (CAD/CAM) abutments in the state of delivery and after ultrasonic cleaning. A total of 28 CAD/CAM monotype and hybrid abutments were cleaned and disinfected applying a three-stage ultrasonic protocol (Finevo protocol). Before and after cleaning, the chemical composition and the contamination of the abutments were assessed using scanning electron microscopy (SEM), dispersive X-ray spectroscopy (EDX), and computer-aided planimetric measurement (CAPM). In the delivery condition, monotype abutments showed a significantly higher amount of debris compared to hybrid abutments (4.86 ± 6.10% vs. 0.03 ± 0.03%, p < 0.001). The polishing process applied in the laboratory after bonding the hybrid abutment components reduces the surface roughness and thus contributes substantially to their purity. The extent of contamination caused by computer-aided manufacturing of custom abutments can be substantially minimized using a three-stage ultrasonic protocol.

The effectiveness of behavioral interventions to improve oral health in adolescents at different periods of follow-up: A systematic review and meta-analysis. PATIENT EDUCATION AND COUNSELING 2020; 103:725-733. [PMID: 31813713 DOI: 10.1016/j.pec.2019.11.030] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/04/2019] [Revised: 11/19/2019] [Accepted: 11/29/2019] [Indexed: 06/10/2023]
Abstract
BACKGROUND The aim of this review was to examine the effectiveness of behavioral interventions at different follow-up periods to improve adolescents' oral health. METHODS CENTRAL, MEDLINE, EMBASE and other databases were systematically searched. Inclusion criteria were as follows: participants aged 10-19 years old, randomized controlled trials using behavioral interventions, outcome measurements including oral health knowledge, attitudes, practices, and oral health status. For each included study, behavior change techniques (BCT) were identified and the quality and risk of bias assessments obtained. PROSPERO reference: CRD42018090341. RESULTS After searching and screening, 17 clinical trials were included in the systematic review. The most commonly used BCTs were behavior health link, information on consequences, and social comparisons. A significant reduction of plaque index was detected (SMD:-0.46; 95 % CI:-0.82∼-0.10) for 3 months and (SMD:-0.71; 95 % CI:-1.08∼-0.33) for 6 months. The reduction of gingival index after 6 months was also significant (SMD:-0.90; 95 % CI:-1.33∼-0.47). Oral health knowledge and oral health-related behavior were also improved after behavioral interventions. CONCLUSION There is moderate evidence that behavioral interventions are effective in promoting oral health in adolescents. To establish more evidence-based conclusions, further research should focus on: quality control of interventions, full descriptions regarding the BCT, long-term follow-ups, and behavior change reinforcements. PRACTICAL VALUE Given the need of early prevention of oral diseases, well-designed oral health promotion programme are needed to improve behavior and outcome of adolescents' oral health.

Abstract
Background
A new NHS dental practice contract is being tested using a traffic light (TL) system that categorises patients as being at red (high), amber (medium) or green (low) risk of poor oral health. This is intended to increase the emphasis on preventative dentistry, including giving advice on ways patients can improve their oral health. Quantitative Light-Induced Fluorescence (QLF™) cameras (Inspektor Research Systems BV, Amsterdam, the Netherlands) also potentially offer a vivid portrayal of information on patients’ oral health.
Methods
Systematic review – objective: to investigate how patients value and respond to different forms of information on health risks. Methods: electronic searches of nine databases, hand-searching of eight specialist journals and backwards and forwards citation-chasing followed by duplicate title, abstract- and paper-screening and data-extraction. Inclusion criteria limited studies to personalised information on risk given to patients as part of their health care. Randomised controlled trial (RCT) – setting: NHS dental practice. Objective: to investigate patients’ preferences for and response to different forms of information about risk given at check-ups. Design: a pragmatic, multicentred, three-arm, parallel-group, patient RCT. Participants: adults with a high/medium risk of poor oral health attending NHS dental practices. Interventions: (1) information given verbally supported by a card showing the patient’s TL risk category; (2) information given verbally supported by a QLF photograph of the patient’s mouth. The control was verbal information only (usual care). Main outcome measures: primary outcome – median valuation for the three forms of information measured by willingness to pay (WTP). Secondary outcomes included toothbrushing frequency and duration, dietary sugar intake, smoking status, self-rated oral health, a basic periodontal examination, Plaque Percentage Index and the number of tooth surfaces affected by caries (as measured by QLF). Qualitative study – an ethnography involving observations of 368 dental appointments and interviews with patients and dental teams.
Results
Systematic review – the review identified 12 papers (nine of which were RCTs). Eight studies involved the use of computerised risk assessments in primary care. Intervention effects were generally modest, even with respect to modifying risk perceptions rather than altering behaviour or clinical outcomes. RCT – the trial found that 51% of patients identified verbal information as their most preferred form, 35% identified QLF as most preferred and 14% identified TL information as most preferred. The median WTP for TL was about half that for verbal information alone. Although at 6 and 12 months patients reported taking less sugar in drinks, and at 12 months patients reported longer toothbrushing, there was no difference by information group. Qualitative study – there was very little explicit risk talk. Lifestyle discussions were often cursory to avoid causing shame or embarrassment to patients.
Limitations
Only 45% of patients were retained in the trial at 6 months and 31% were retained at 12 months. The trial was conducted in four dental practices, and five dental practices were involved in the qualitative work.
Conclusions
Patients prefer personal, detailed verbal advice on oral health at their check-up. A new NHS dental practice contract using TL categorisation might make this less likely.
Future work
Research on how to deliver, within time constraints, effective advice to patients on preventing poor oral health. More research on ‘risk work’ in wider clinical settings is also needed.

Abstract
Aim. To test the efficiency and acceptance of school-based dental education for improving oral self-care in Mexican elementary school-aged children. Method. A total of 408 students from 4 schools were examined at the baseline, 3 months (follow-up rate was 94%) and 6 months observations (follow-up rate 91%). Group 1 served as a control, Group 2 received a lecture-based education, and Group 3 consisted of trained peer-leaders who educated their peers. Oral self-care practice and oral self-care skills were assessed at the baseline and both follow-ups. A number of sociodemographic and oral health behavior/knowledge characteristics were tested as predictors of oral self-care outcomes at different observation periods. Results. Oral self-care outcomes improved in Groups 2 and 3, but not in the control group. The selected child population, their caregivers and teachers perceived the school-based educational strategy as important and necessary. There was no consistent pattern of predictors explaining variations in oral self-care outcomes at any of the observation periods. Oral self-care improvement observed at the 6 months observation was mainly predicted by the baseline oral self-care levels, dental education, and age. Conclusions. The school-based dental education was easy to implement, and it was effective for improving children's oral self-care practice and skills.

Abstract
Introduction A new dental contract being tested in England places patients into traffic light categories according to risk (Red = High risk). This reflects health policy which emphasises patients' shared responsibility for their health, and a growing expectation that clinicians discuss health risk in consultations. Alongside this, there are technological developments such as scans and photographs which have generated new, vivid imagery which may be used to communicate risk information to patients. However, there is little evidence as to whether the form in which risk information is given is important. Methods The PREFER study is a pragmatic, multi-centre, three-arm, patient-level randomised controlled trial, based in four NHS dental practices, from which 400 high/medium risk patients will be recruited. The study compares three ways of communicating risk information at dental check-ups: 1) verbal only (usual care); 2) a Traffic Light graphic with verbal explanation; 3) a Quantitative Light-Induced Fluorescence (QLF) photograph showing, for example, patches of red fluorescence where dental plaque has been present for two days or more (with a verbal explanation). The study assesses patient preferences using the economic preference-based valuation methodology Willingness-to-Pay (WTP). Any changes in oral self-care (for example in tooth-brushing), will be measured by self-report, and clinical outcome data collected by clinicians and extracted from QLF photographs. Predictors and moderators of any behaviour change will be explored using demographic characteristics and psychological variables from the Extended Parallel Process Model. A cost-benefit framework will explore the financial implications for NHS dentistry of the three risk presentation methods.

Abstract
AIM To evaluate the efficiency of social-cognitive theory-guided oral hygiene interventions in adolescents and to identify predictors of adolescents' self-care practice. DESIGN A cluster randomized trial included 197 15- to 16-year-olds from two secondary schools. The intervention group received three face-to-face educational hands-on sessions facilitated by a dentist and adolescents worked in pairs. Individual dental plaque levels were measured at baseline, after intervention, at six and at 12 months. The structured questionnaire inquired about gender, family socio-economic status (baseline), and different social-cognitive domain variables (baseline, six, and 12 months). RESULTS At baseline, there were no statistically significant differences in dental plaque scores between the intervention and control groups (P = 0.183). At the 6-month follow-up, the intervention group had significantly less dental plaque than the control group (P = 0.047), but the intergroup difference in dental plaque levels was not significant at the 12-month follow-up (P = 0.400). Variations in dental plaque levels at different time periods were explained by the following predictors: family's socio-economic status, social-cognitive domain variables, group affiliation, and baseline plaque levels. CONCLUSIONS Social-cognitive theory-guided interventions improved oral self-care of adolescents in the short term. After the intervention was discontinued, the improvement in oral self-care of adolescents lasted for another 5 months.

Abstract
The koala is one of Australia's most highly specialized folivores with a diet exclusively of eucalyptus leaves to provide all nutritive needs and therefore requires to be free of oral disease as they are dependent on good dentition for optimal health and quality of life. We developed an oral examination methodology based on protocols for companion animals and human dentistry to chart the oral health of koalas. Thirty free-ranging koalas from South-East Queensland, Australia were examined for general body and oral health. Inspection of the oral cavity was conducted for the presence or absence of the indicators of oral disease such as caries or periodontal disease. Univariate and multivariate analyses were performed on the examination data and a prototype oral health chart developed. The prototype was then trialled and the methodology validated by the Kappa statistic using ten additional koalas examined by four multidisciplinary personnel involved in koala care. Trauma associated fractures, tooth displacement, abnormal occlusion and tooth wear, compacted vegetation, extrinsic stain deposits, periodontal bone loss, gingivitis, tooth mobility, and calculus were present in the oral cavities of the examined koalas. A system of scoring between 0 and 3 was constructed in accordance with current koala general health charting formats. Validation of the charting method using Kappa coefficients of agreement statistics indicated that there was a good agreement among observers on recorded results except for inflammation and calculus scoring. Modifications were made and visual aids and index scales produced to further assist observers. Oral health surveillance has been proven in other species to be significant in diagnosing physiological disturbances derived from environmental, genetic, and developmental causes. Veterinarians, dental researchers, and koala husbandry personnel will benefit in using this charting method and reporting the oral health of koala populations in their future findings. This unique form of oral health monitoring would be adaptable to other mammals.

Abstract
This study examined whether the authoritative parenting model (APM) is more effective than conventional approaches for changing adolescent oral hygiene behavior. A total of 247 adolescents were recruited using a cluster random-sampling method. Subject groups were randomly allocated into an intervention group (APM-based interventions), a Control Group 1 (conventional dental education and behavior modification) or a Control Group 2 (conventional behavior modification). The results were assessed after 3 and 12 months. Oral hygiene level was assessed as percent dental plaque and the ratio of plaque percent change (RPC). At the 3-month follow-up, there were significant differences among the groups; the APM group had the largest decrease in plaque levels (24.5%), Control Group 1 showed a decrease in plaque levels of 15.4% and Control Group 2 showed an increase in plaque levels of 2.8%. At the 12-month follow-up, an improvement was observed in all groups, but there were no statistically significant differences among the groups. In the short term, the intervention based on the APM was more effective in changing adolescent oral hygiene behavior compared with the conventional approaches. The reasons for long-term positive change after discontinued interventions in control groups need to be explored in future studies.

Abstract
The goal of this study was to examine salivary factors and formation of dental plaque in elderly subjects who were institutionalized and to relate these factors to general health and medication use. This cross-sectional study consisted of 50 elderly individuals who were institutionalized and 25 healthy young volunteers who served as a reference group. For each subject, salivary flow rates, salivary pH, and buffering capacity were assessed. Baseline Plaque Index and Plaque Formation Rate Index were used as a measure of oral hygiene. Information on each patient's general health and medication use was acquired from the institution. An evaluation of the results of this study suggests that salivary protective qualities and dental plaque levels in the elderly subjects who were institutionalized were worse than in healthy young individuals. An association between the general health of the elderly and salivary flow rate was found.

Abstract
OBJECTIVE The aim of this study was to overview the effectiveness of different strategies used to promote oral health in adolescents. METHODS A search of the MEDLINE via OVID database was performed through September 2007. The studies aiming to modify oral health-related lifestyle in adolescents with experimental pre- to post-test controlled study design were targeted. Oral health-related knowledge, attitudes, oral hygiene status, gingival health, and caries status were used as outcome measures for the evaluation of changes in adolescent oral health-related behaviour. RESULTS All studies evaluating knowledge showed cognitive gains. Only slight or no improvement in attitude was reported. The average improvement in oral hygiene was 30-50%. A wide range 0-50% of the effects on gingival health was presented. However, the relapse in oral hygiene status towards baseline values was also observed. Only studies employing professionally applied preventive measures in conjunction with educational activities reported significantly lower caries incidence. CONCLUSION The limited success of the behavioural interventions and the lack of diversity in methods used do not allow identification of the best ways to promote oral health towards adolescents. Therefore, alternative approaches for oral health promotion in adolescents should be explored.
