The burden of dental care in Amelogenesis Imperfecta paediatric patients in the UK NHS: a retrospective, multi-centred analysis.

PURPOSE: The burden of dental care in Amelogenesis Imperfecta (AI) has not been well described. This condition results in weak, discoloured and often sensitive teeth. Specialist paediatric care is available for AI patients in the UK, but treatment protocols and care provided are inconsistent. The aim of this study was therefore to analyse the provision of treatment and burden of care for children and families with AI across four Paediatric Dentistry centres in the UK. METHODS: A retrospective evaluation of AI patient clinical records across four UK consultant-led Paediatric Dentistry centres was completed. Frequency and duration of care were recorded along with treatment and experience of inhalation sedation, local and general anaesthetic. RESULTS: In total, 138 records were available for analysis. The average patient age at first referral was 7.7 years (range 1-16 years) and families travelled an average 21.8 miles per appointment (range 0.2-286 miles). Patients attended on average 4.5 appointments per year for 5.8 years. In total, 65.2% had experience of local anaesthetic, 27.5% inhalation sedation and 31.9% general anaesthetic. Dental treatment including restorations and extractions were commonly required on multiple teeth per patient. CONCLUSION: AI carries a high burden of specialist dental care to patients and families. Specialist centres are required to provide longitudinal, comprehensive care.

Genetic testing for amelogenesis imperfecta: knowledge and attitudes of paediatric dentists.

Introduction: Genetic testing is increasingly applied across healthcare reflecting the value to diagnosis, clinical decision-making, service organisation and advancement of the research-informed evidence base. Patient expectations are changing. Genetic testing has not been part of dental practice. Introduction of an NHS-targeted gene panel test for amelogenesis imperfecta (AI), a heterogeneous genetic disorder affecting enamel appearance and function, represents a paradigm shift. This impacts on specialists in paediatric dentistry and other members of the dental team delivering longitudinal care for individuals with AI. Aim: To evaluate the opinions of paediatric dentists on genetic testing for dental conditions using AI as the exemplar. Method: Two focus groups of nine UK NHS paediatric dentists each were audio recorded (September 2016) and transcribed verbatim. Qualitative analysis was undertaken using Interpretative Phenomenological Analysis (IPA). Results: A wide range of views reflected existing insight and understanding. Three core concepts of justification, ownership and challenges emerged. The clinicians were generally open to involvement with genetic testing in paediatric dentistry, but required more support. Conclusion: Areas for clarification and professional development were identified as important in ensuring that genetic testing in dentistry, which is currently in its infancy, reaches translational potential and enhances patient care as this area of healthcare continues to advance rapidly.

Molar incisor hypomineralisation: experience and perceived challenges among dentists specialising in paediatric dentistry and a group of general dental practitioners in the UK.

AIM: To assess the views and experience of the UK dentists specialising in paediatric dentistry (trainees) about molar incisor hypomineralisation (MIH) and compare the findings with the responses from a group of UK general dental practitioners. METHOD: A web-based questionnaire was sent to dentists undergoing specialist training in paediatric dentistry. The same questionnaire was completed by a group of general dentists who stated an interest in treating children, with various levels of experience. The questionnaire sought information on clinical experience and the views of the dentists on the impact of MIH on children and families. RESULTS: Specialty trainees (37) from different paediatric dental departments in the UK completed the online survey, giving a total response rate of 71%. The questionnaire was also completed by 31 general dental practitioners. There was difficulty in distinguishing MIH from other conditions for both groups. Increased sensitivity of affected teeth was the most frequently encountered problem with 51% of the trainees and 76% of the dentists saying this was often or always a challenge. The trainees were particularly concerned about the pain children experienced and about the appearance of the condition. Both groups felt that parental anxiety occurred in almost all cases. CONCLUSIONS: Both groups felt that MIH presents several clinical challenges and has a negative effect on the quality of life of the affected children and their families. There were significant differences in the views and perceptions between the two groups.

An evaluation of paediatric dental general anaesthesia in Yorkshire and the Humber.

BACKGROUND: Following major change in UK policy regarding dental general anaesthesia (DGA) in 2001, there appears to be little information available about paediatric DGA services, their organisation, availability and utilisation. AIMS: To establish the location, organisation and monitoring systems of paediatric DGA services in Yorkshire and the Humber Strategic Health Authority and to audit these services against existing standards of best practice. DESIGN: A postal survey of all potential paediatric DGA providers in Yorkshire and the Humber. RESULTS: Thirty-one possible DGA service providers were identified, 24 of which provided paediatric DGAs. Of 84 DGA lists identified, 75 regularly treated children, and nine were run on an ad hoc basis. The lists were held in 20 centres. The number of patients treated per list varied depending on treatment provided, ranging from 3.9 to 7.5 patients per list. Maximum waiting times varied from three to 84 weeks. Outcome data recording methods varied. Just over half of respondents used the Hospital Episode Statistics system; the remainder used other systems, or none. CONCLUSIONS: There was much variation in how DGA lists were organised. Most lists met some of the accepted standards, but very few met all. Waiting times were largely in accordance with national targets.

Prevalence of enamel defects and MIH in non-fluoridated and fluoridated communities.

AIM: This was to study the prevalence of enamel defects and molar incisor hypomineralisation (MIH) in children attending Leeds Dental Institute (UK) and Westmead Dental Hospital, Sydney (Australia). METHODS: Prospective dental examinations were carried out on 25 children referred to two orthodontic departments. A questionnaire was completed to obtain background information and about previous fluoride (F) exposure followed by an oral examination. First permanent molars and permanent incisors were examined for presence, type and severity of enamel defects using the modified DDE screening index. Chi square tests were used to compare results. RESULTS: Data for 24 children in Sydney and 20 in Leeds presented with at least one enamel defect. Of 300 teeth examined, 155 in Sydney and 82 in Leeds had a defect (p < 0.005). Severity of enamel defects was higher in Sydney. The children presenting with any type of enamel defect in at least one incisor or molar were 21 in Sydney and 10 in Leeds. However, if only demarcated defects were considered, the number in Sydney dropped to 11 and in Leeds remained at 10. CONCLUSIONS: There was a higher prevalence of enamel defects in those children living in F Sydney than in non-F Leeds, but the prevalence of MIH was the same supporting the view that F is not associated with the aetiology of MIH.
