University Teachers Group
Join me for this year’s University Teachers Group session at the BOC, which entails presentations of research from trainees / residents in the UK.
This year there were 8 presentations covering the topics of; an RCT on bonding rates of tooth surface preparation Vs no preparation, evidence from adverts in orthodontic journals, reporting in RCTs, appropriate sample sizes in orthodontic RCTs, extraction decision making, shared decision making in orthodontics, student perception of face to face Vs virtual learning, gender as a barrier to a career in orthodontics
Randomised Control Trial to compare preparation of molars for orthodontic bonding with and without a tungsten Carbide Bur Miesha K Virdi
Hypothesis
- Preparation of a molar with a Carbide bur had no effect on failure rate
Method
- Prospective RCT
- Split mouth technique – Battenburg design
- 12 month follow up
Results
- Without bur = 12.8%
- With bur 7.9% – 5% reduction
- Maxillary molar fails greater than Mandibular molar – statistically significant ()due to parotid gland)
- Mainly reduce upper molar debonds, by 10%
- Gender – no difference in male and female
Conclusion
- Clinical reduction in Carbide bur, but not statistical difference
Othman Hameed Advertisement in Orthodontic Journals. Are they evidence-based
Aim
- Assess evidence of claims of clinical superiority
Methods
- Cross sectional study
- Validated criteria
Results
- 35% supported by evidence
- 65% unsupported by evidence
- Majority of evidence presented
- Anecdotal
- No difference in journals
Conclusion
- Majority of adverts of clinical superiority of product are not supported
- 2% support with high level of evidence
Correct Labelling of Orthodontics Randomised Control Trials
Georgina Kane
Aims
- Access whether labels are true RCTs (allocation and randomisation described)
Methods
- Systematic review of orthodontic RCTs
Results
- N = 173 trials
- 170 have randomised, 109 described RCTs 64%
- 30% 51 = unclear
- 6% not RCTs
Predictors of correct labelling
- Journal type, country, involvement of statisticition
Outcome
- 1 in 3 trials inadequate labelling
Are treatment effect assumptions in orthodontic studies overoptimistic? Daniel Stonehouse-Smith
Background
Sample size – effect size – assumptions can be exaggerated in medicine
A prior statement of clinical significance / sample of convenience
Method
Systematic review
Results
- A sample size described in 31.7%
- Significant difference between the assumed and observed treatment effects suggesting greater values for the assumed effect sizes.
Recommendation
Avoid A priori effect size in sample size calculation
A qualitative evaluation of attitudes towards extractions amongst primary care in orthodontics
Aims
Evaluate factors affecting extraction choses among orthodontists in extraction
Method
- Qualitative analysis 1:1
- Topic guide
- Themes
- Patient related factors
- Poor dental health = extractions
- 3RD Molars greater extractions
- Patient related factors
- Adults – avoid extractions due to space closure
- Operator related factors
- Observing treatment long term = tend to result in more extraction treatment
- Setting
- Poorer socio-economic factors = greater extractions
- Private Vs NHS small factor
- Mechanical approaches
- Less use of headgear = greater extractions
- IPR concerns of use in adolescence, more use in adults
- Self directed learning
- Peer learning
Shared Decision Making in Adult Orthodontic Patients: A cross sectional study
Farnaz Motamedi-Azari
Aims
Adult preferred roles in healthcare decision making
Adult perceived roles in healthcare decision making
Method
- Cross sectional study
- Control preference scale CPS – validated questionnaire
Results
- Perceived roles more passive then preferred
- Genders males preferred more passive, females preferred more active roles
- 45% perceived and preferred roles matched, 55% perceived and preferred roles not matched
- 35% wanted more active role
- 16% wanted more passive role
Conclusion
- Patients vary in there preferred role in HDM
- Gender, females prefer active roles, males prefer passive
- We may need to educate patients on benefits on shared decision making as it enhances patient outcomes to treatment
Postgraduate student perception of face to face and distance education in orthodontics Oliver Johnson King
Aims
Compare and contrast face to face Vs distance learning education
Method
- UCL students
- Focus groups – online, with topic guide
- Transcribed by professional company
- 25 students = 83% of students
Thematic analysis
- Social support Network
- Distance learning resulted in lack of bonding
- Technology
- Quality of the internet connection effected quality of learning
- Cost of new technology
- Experience
- Education
- Interaction
- Effective teaching and learning
- Difficulty learning practical skills
- Theory, preferred online than face to face
Conclusions
- Face to face
- Social peer learning, practice learning
- Virtual learning
- Accessibility of resources, convenient, theoretical learning
Investigating the barriers and facilitator to an orthodontic career, does gender have an effect Jennifer Jopson
Background
- Majority of dentists, orthodontists and academic are female
- Occluational feminisation
Method
- Qualitative
- Purposive sampling, focus group, inductive thematic analysis
Results
- Motivation
- Career longevity
- Financial renumeration
- Facilitators
- Mentors – key to Post CCST training
- Support
- Barriers
- National retirement
- Inflexible training, buy a house, have family, children
- Finance
- Fatigue
- Gender difference
- Difference in females Vs males
- Females
- Balance work with children difficult
- Career = Guilt at not being able to ‘do it all’ family and job
- Males – balance with work and other opportunities
- Easier to start family
- Career = based on right place
- Discussion
- Significant effect of guilt on working mothers
- Attitutes of ‘good mothers’ remains present in society
- Significant effect of guilt on working mothers
- Females
- Difference in females Vs males
Conclusion
- Pressure points in a career
- Male and Female have difference career experience
