The Restorability Assessment and Endodontic Access Cavity Interface

Successful root canal treatment requires management of the bacterial infection within the root canal space and protection of residual tooth structure with direct/indirect restorations. Long-term success depends upon prevention of re-infection of the root canal space as well as ensuring favorable distribution of the occlusal forces throughout the residual tooth structure. Appropriate planning and design of the final restoration prior to initiating root canal treatment is paramount in achieving this objective. This article describes simultaneous restorability assessment and access cavity preparation to optimize outcome of both endodontic and prosthodontic treatment of the endodontically involved tooth.

Root caries development in older adults- a prospective cohort study

Objectives: To identify factors associated with root caries development during a two year period in a population of independently living older adults. Methods: A prospective cohort study was carried out with 334 independently living volunteers aged 65 and older. At baseline (t0), each participant completed a questionnaire which recorded age, gender, medical history, fluoride exposure, oral and denture hygiene practices, smoking and alcohol consumption, diet information, and socio economic information. Clinical examinations were performed and stimulated saliva samples were collected. Patients were reviewed 12(t1) and 24(t2) months later to determine the root caries increment. Results: 307 adults were assessed at t1 and 280 were assessed at t2 with 83.8% of participants examined at 24 months. Incidence of root caries in this cohort was 17.4% at t1 and 21.6% at t2. The mean root caries increment was 0.43 (SD 1.45) surfaces at t1 and 0.70 (SD 1.86) surfaces at t2. Age >70 years, completing education at primary level, poor oral hygiene, xerostomia, coronal decay at baseline, higher root caries index at baseline and number of exposed root surfaces showed a statistically significant association (P < 0.05) with root caries development. Conclusion: Root caries is a substantive dental health problem for our older population. Root caries prevention strategies should be targeted at older adults who have poor plaque control and high levels of caries experience. In particular patients with xerostomia should be targeted with preventive measures.

Specialty Registrars’ Experience of Managing Head and Neck Cancer Patients

Objective The aim of this study was to collate and compare data on the training of Specialty Registrars in Restorative Dentistry (StRs) in the management of head and neck cancer (HANC) patients across different training units within the UK and Ireland. Methods Current trainees were invited to complete an online questionnaire by the Specialty Registrars in Restorative Dentistry Group (SRRDG). Participants were asked to rate their confidence and experience of assessing and planning treatment for HANC patients, attending theatre alone and manufacturing surgical obturators, and providing implants for appropriate cases. Respondents were also asked to appraise clinical and didactic teaching at their unit, and to rate their confidence of passing a future Intercollegiate Specialty Fellowship Examination (ISFE)-station assessing knowledge of head and neck cancer. Results Responses were obtained from 21 StRs (n=21) training within all five countries of the British Isles. Most respondents were based in England (76%), with one StR in each of Scotland, Wales, Northern Ireland and the Republic of Ireland. A third (33%) were in their 5th year of training. Almost half of the StRs indicated that they were confident of independently assessing (48%) new patients with HANC, with fewer numbers reporting confidence in treatment planning (38%). The majority (52%) of respondents indicated that they were not confident of attending theatre alone and manufacturing a surgical obturator. A third (33%) rated their experience of treating HANC patients with implants as ‘poor’ or ‘very poor’, including three StRs in their 5th year of training. Less than one third (<33%) rated didactic teaching in maxillofacial prosthodontics at their unit as ‘good’ or ‘excellent’, and only 7 StRs indicated that they were confident of passing an ISFE-station focused on HANC. Conclusion Experience and training regarding patients with head and neck cancer is inconsistent for StRs across the UK and Ireland with a number of trainees reporting a lack of clinical exposure.

The prevalence of caries in patients referred for orthodontic assessment in Northern Ireland – A retrospective study

Objectives: To determine the prevalence of untreated carious lesions in permanent teeth in patients (under the age of 18) referred for an orthodontic assessment in specialist practice. In addition, the figures shall be compared with national data for Northern Ireland (as outlined in the recent Child Dental Health Survey 2013)
The Gold standard would be that 100% of patients would be caries free upon presentation.

Methods: The clinical records and radiographs (OPT of quality grading 1 or 2) of 337 patients were reviewed. This encompassed patients who had an orthodontic assessment carried out in specialist practice over a 6 month period (following referral from their general dental practitioner)

Results: A total of 337 patient records were examined. Of these, 149 were male (44.2%) and 188 were female (55.8%), with an age range of 7-17 years at the time of new patient assessment. It was found that 36 patients (10.7%) had evidence (clinical and/or radiographic) of active and untreated dental caries. Of those affected, 14 were male and 22 were female.
Breaking the data down in terms of age, we can also get some indication as to how this cohort compares with national data for Northern Ireland :⃰

7-10 years (Mean = 9.3) = 14.3% caries (versus NI average of 6% for 8 year olds)
11-13 years (Mean = 12.1) = 10.1% caries, (versus NI average of 16% for 12 year olds)
14-17 years (Mean = 15.2) = 9.1% caries (versus NI average of 15% for 15 year olds)

⃰using the diagnostic threshold “Decay into dentine (visual dentine caries excluded)”


Conclusion: In this sample group, a total of 10.7% of patients (9.4% of males, 11.7% of females) presented with evidence of undiagnosed caries upon being assessed as a new patient in specialist orthodontic practice. Hence, the gold standard was not met.

Evaluation of Restorative Dentistry Specialty Registrars’ Clinical Experience of Developmental Disorders: A Survey

Background

Specialty Registrars in Restorative Dentistry (StRs) should be competent in the independent restorative management of patients with developmental disorders including hypodontia and cleft lip/palate upon completion of their specialist training.1 Knowledge and management may be assessed via the Intercollegiate Specialty Fellowship Examination (ISFE) in Restorative Dentistry.2

Objective

The aim of this study was to collate and compare data on the training and experience of StRs in the management of patients with developmental disorders across different training units within the British Isles.

Methods

Questionnaires were distributed to all StRs attending the Annual General Meeting of the Specialty Registrars in Restorative Dentistry Group, Belfast, in October 2015. Participants were asked to rate their confidence and experience of assessing and planning treatment for patients with developmental disorders, construction of appropriate prostheses, and provision of dental implants. Respondents were also asked to record clinical supervision and didactic teaching at their unit, and to rate their confidence of passing a future ISFE station assessing knowledge of developmental disorders.

Results

Responses were obtained from 32 StRs (n=32) training within all five countries of the British Isles. The majority of respondents were based in England (72%) with three in Wales, and two in each of Scotland, Northern Ireland, and the Republic of Ireland. Approximately one third of respondents (34%) were in the final years of training (years 4-6). Almost half of the StRs reported that they were not confident of independently assessing (44%) new patients with a developmental disorder, with larger numbers (72%) indicating a lack of confidence in treatment planning. Six respondents rated their experience of treating obturator patients as ‘poor’ or ‘very poor’. The majority (56%) rated their experience of implant provision in these cases as ‘good’ or ‘excellent’ with three-quarters (75%) rating clinical supervision at their unit as ‘good’ or ‘excellent’. Less than half (41%) rated the didactic teaching at their unit as ‘good’ or ‘excellent’, and only 8 StRs indicated that they were confident of passing an ISFE station focused on developmental disorders.

Conclusion

Experience and training regarding patients with developmental disorders is inconsistent for StRs across the British Isles with a number of trainees reporting a lack of clinical exposure.

Current status of Gerodontology teaching in Europe: preliminary findings

Aim(s): The aim of this study was to explore the findings of a survey on the prevalence, contents and status of Gerodontology teaching amongst the European Dental Schools.
Materials and Methods: A first wave of emails, including an electronic questionnaire in English, and two weeks later a first reminder, were sent to the Deans or other contact persons in 185 dental schools in 40 European countries. The electronic questionnaire recorded the prevalence, contents and status of Gerodontology education at the undergraduate, postgraduate and continuing education levels.
Results: The first wave of responses included 70 dental schools from 28 countries. Gerodontology was included in the undergraduate curricula of 77% of the respondents and was compulsory in 61% of them. It was taught as an independent course in 39% of the respondents. When embedded in other courses, these were mainly the Prosthodontics lectures. Clinical training in Gerodontology was on the curriculum of 56% of the respondents. Sixteen percent of the schools had a Gerodontology Division, and 43% an assigned Programme Director. Gerodontology was taught in the postgraduate programmes of 33% of the schools, again mostly embedded in Prosthodontic programmes. Continuing education courses in Gerodontology were offered by 34% of the responding schools.
Discussion and Conclusions: When interpreting the results of this still ongoing study, a "worst case scenario" has to be born in mind, where dental schools, who failed to participate in the survey, may not be teaching in Gerodontology. Under this perspective, a moderate prevalence of Gerodontology is recorded in the undergraduate curricula of European dental schools. At a postgraduate level, it is less frequently offered, and mainly embedded in the Prosthodontic programmes. European guidelines on the dental curriculum might help to increase awareness and introduce Gerodontology to undergraduate, postgraduate and continuing education.

Embracing an integromic approach to tissue biomarker research in cancer: Perspectives and lessons learned

Modern approaches to biomedical research and diagnostics targeted towards precision medicine are generating ‘big data’ across a range of high-throughput experimental and analytical platforms. Integrative analysis of this rich clinical, pathological, molecular and imaging data represents one of the greatest bottlenecks in biomarker discovery research in cancer and other diseases. Following on from the publication of our successful framework for multimodal data amalgamation and integrative analysis, Pathology Integromics in Cancer (PICan), this article will explore the essential elements of assembling an integromics framework from a more detailed perspective. PICan, built around a relational database storing curated multimodal data, is the research tool sitting at the heart of our interdisciplinary efforts to streamline biomarker discovery and validation. While recognizing that every institution has a unique set of priorities and challenges, we will use our experiences with PICan as a case study and starting point, rationalizing the design choices we made within the context of our local infrastructure and specific needs, but also highlighting alternative approaches that may better suit other programmes of research and discovery. Along the way, we stress that integromics is not just a set of tools, but rather a cohesive paradigm for how modern bioinformatics can be enhanced. Successful implementation of an integromics framework is a collaborative team effort that is built with an eye to the future and greatly accelerates the processes of biomarker discovery, validation and translation into clinical practice.

Is it time for standards and a common data exchange format for digital image analysis?

Digital image analysis is at a crossroads. While the technology has made great strides over the past few decades, there is an urgent need for image analysis to inform the next wave of large scale tissue biomarker discovery studies in cancer. Drawing parallels from the growth of next generation sequencing, this presentation will consider the case for a common language or standard format for storing and communicating digital image analysis data. In this context, image analysis data comprises more than simply an image with markups and attached key-value pair metrics. The desire to objectively benchmark competing platforms or a push for data to be deposited to public repositories much like genomics data may drive the need for a standard that also encompasses granular, cell-by-cell data.

Risk indicators associated with root decay in independently living older adults

Objective: To determine the risk indicators associated with root caries experience in a cohort of independently living older adults in Ireland.
Methods: The data reported in the present study were obtained from a prospective longitudinal study conducted on the risk factors associated with root caries incidence in a cohort of independently living older adults (n=334). Each subject underwent an oral examination, performed by a single calibrated examiner, to determine the root caries index and other clinical variables. Questionnaires were used to collect data on oral hygiene habits, diet, smoking and alcohol habits and education level. A regression analysis with the outcome variable of root caries experience (no/yes) was conducted.
Results: A total of 334 older adults with a mean age of 69.1 years were examined. 53.3% had at least one filled or decayed root surface. The median root caries index was 3.13 (IQR 0.00, 13.92). The results from the multivariate regression analysis indicated that individuals with poor plaque control (OR 9.59, 95%CI 3.84-24.00), xerostomia (OR 18.49, 95%CI 2.00-172.80), two or more teeth with coronal decay (OR 4.50, 95% CI 2.02-10.02) and 37 or more exposed root surfaces (OR 5.48, 95% CI 2.49-12.01) were more likely to have been affected by root caries.
Conclusions: The prevalence of root caries was high in this cohort. This study suggests a correlation between root caries and the variables poor plaque control, xerostomia, coronal decay (≥2 teeth affected) and exposed root surfaces (≥37). The significance of these risk indicators and the resulting prediction model should be further evaluated in a prospective study of root caries incidence.
Clinical Significance: Identification of risk indicators for root caries in independently living older adults would facilitate dental practitioners to identify those who would benefit most from interventions aimed at prevention.

Nachrichtendienstpsychologie 3

Der Versuch, nachrichtendienstliche Fragestellungen unter psychologischen Aspekten zu betrachten, ist auf ein positives Interesse gestoßen. In den beiden Bänden Nachrichtendienstpsychologie 1 (Litzcke, 2003) und 2 (Schwan, 2004) der FH Bund erschienen eine Reihe von Aufsätzen, die ein breites Themenspektrum behandeln. Mit Band 1 wurde eine Struktur eingeführt, die sich bewährt hat, und die daher auch für Band 3 beibehalten wird. Die Beiträge des Bandes 3 lassen sich wie folgt zuordnen: 1) Anwendungen vorhandener Konzepte der Psychologie und aus Nachbardisziplinen in den Nachrichtendiensten. Siehe hierzu die Beiträge von Scherer zur Moderation von Qualitätszirkeln im Bundesnachrichtendienst, von Damm und Litzcke zur Akzeptanz des Sicherheitsakteurs „Europa“, von Schwan zur Bedeutung aggressiven Verhaltens für die Arbeit der Nachrichtendienste, von Löhr zum kognitiven Interview und von Wiesen zu den Möglichkeiten einer Gesprächssteuerung. 2) Übertragung psychologischer Methoden auf das Forschungsgebiet Nachrichtendienste zur Gewinnung neuer Ergebnisse / Konzepte. Siehe hierzu die Beiträge von Müller-Enbergs zu den Motiven für eine geheimdienstliche oder nachrichtendienstliche Kooperation bei den inoffiziellen Mitarbeitern der DDR-Staatssicherheit, von Horn zu den Einsatzmöglichkeiten der Operativen Fallanalyse und von Schmalzl zum Konstrukt Einsatzkompetenz. 3) Generierung eigenständiger psychologischer Erkenntnisse und Methoden im Bereich Nachrichtendienste. Dieser Rubrik ist kein Beitrag des Bandes 3 zuzuordnen. Der Abschlussbeitrag von Freitag zur Anwendbarkeit von Täuschungsprinzipien der Zauberkunst in der nachrichtendienstlichen Arbeit entzieht sich dieser Struktur. Der Beitrag ist mit Augenzwinkern geschrieben und soll auch so gelesen werden. Die Themen der Aufsätze sind nicht auf rein nachrichtendienstliche Aufgabenstellungen beschränkt. So werden beispielsweise auch Querschnittsproblematiken behandelt, die nicht nur einem Arbeitsbereich innerhalb der Nachrichtendienste zuzuordnen wären. Damit werden auch Themen behandelt, die ebenso in anderen Behörden und Institutionen von praktischer Relevanz sein können. So ist beispielsweise die Einrichtung von Qualitätszirkeln kein spezifisches Thema der Nachrichtendienste. Da sich aber auch Nachrichtendienste mit der Qualitätssteigerung ihrer Arbeit befassen, ist es angezeigt, entsprechende Ausarbeitungen in die Reihe Nachrichtendienstpsychologie zu integrieren. Auch in Band 3 werden interdisziplinäre Ansätze und Verknüpfungen mit der Polizeipsychologie vorgestellt, auch wenn die dort entwickelten Erkenntnisse und Methoden nicht ungeprüft auf nachrichtendienstliche Aufgabenstellungen übertragen werden können. Gleichwohl können sich aus dem Kontakt zur Polizeipsychologie Anregungen für die Nachrichtendienstpsychologie ergeben.
