This study shows that it is possible to use 3D imaging to store dental study models for treatment monitoring and research with a satisfactory degree of accuracy.

Within the limits of this laboratory investigation it is concluded that severely damaged and root filled maxillary premolars, restored with direct resin composite complete crowns without posts have similar fracture resistances and failure modes compared to those with various posts, which suggest that posts are not necessarily required.

Introduction The outbreak of COVID‐19 necessitated a move to online teaching and assessment. The objective structured clinical examination (OSCE) has been an integral part of dental examinations for several decades. The COVID‐19 pandemic stopped face to face examinations around the world. An Online Virtual OSCE (VOSCE) was developed and piloted for dental undergraduate assessment. Materials and Methods This initial report outlines the steps required to run an OSCE online. Planning and preparation required in adaptation of an OSCE for the online environment is dreported. The necessity for familiarisation sessions is addressed, and VOSCE logistics described. Results With careful planning, the VOSCE is a useful assessment method in difficult times. Feedback from staff and students was favourable. Conclusion Although significant organisation was required, the examination process worked well for both students and examiners. Despite limitations in relation to technical dental procedures, the VOSCE could be a viable alternative to face to face clinical examination.

Objective : Objective measure of scarring and three-dimensional (3D) facial asymmetry after surgical correction of unilateral cleft lip (UCL) and unilateral cleft lip (UCLP). It was hypothesized that the degree of scarring or asymmetry would be correlated with poorer psychological function. Design : In a cross-sectional design, children underwent 3D imaging of the face and completed standardized assessments of self-esteem, depression, and state and trait anxiety. Parents rated children's adjustment with a standard scale. Setting : Glasgow Dental School, School of Medicine, College of Medical, Veterinary and Life Sciences. Patients : Fifty-one children aged 10 years with UCLP and 43 with UCL were recruited from the cohort treated with the surgical protocol of the CLEFTSIS managed clinical network in Scotland. Methods : Objective assessment to determine the luminance and redness of the scar and facial asymmetry. Depression, anxiety, and a self-esteem assessment battery were used for the psychological analysis. Results : Cleft cases showed superior psychological adjustment when compared with normative data. Prevalence of depression matched the population norm. The visibility of the scar (luminance ratio) was significantly correlated with lower self-esteem and higher trait anxiety in UCLP children (P  =  .004). Similar but nonsignificant trends were seen in the UCL group. Parental ratings of poorer adjustment also correlated with greater luminance of the scar. Conclusions : The objectively defined degree of postoperative cleft scarring was associated with subclinical symptoms of anxiety, depression, and low self-esteem.

Introduction: COVID-19 has profoundly affected dental undergraduate teaching and assessment. The pandemic resulted in cessation of face-to face teaching and assessment in many countries, with an associated move online. Objective structured Clinical Examination (OSCE), an important modality for clinical assessment in dentistry and medicine, is not possible with pandemic restrictions in place. As a result, interest in virtual objective structured clinical examination (VOSCE) has been revived. Student and staff evaluation of any assessment process is important, where the views of all involved are required in establishment of authenticity. This papers aims to explore and describe the views of undergraduate dental students and staff in relation to VOSCE Materials and Method: Qualitative methods utilising online focus groups and video recording were used in this study. Five focus groups, involving 24 participants were undertaken.Results: Thematic analysis following a deductive semantic approach was carried out resulting in the identification of six themes relating to the VOSCE: VOSCE preconceptions, examination preparation, examination process, fairness, comparison with OSCE and possible improvements. Consideration of these themes, and their interaction, is likely to prove important for optimisation of this assessment modality.Conclusions: Overall, both staff and students considered the VOSCE a useful and fair examination and a suitable alternative to OSCE. The potential for a number of improvements in the assessment process was identified.

Despite surgical intervention at an early age, asymmetry remains significant in cleft patients at 10 years of age. Three-dimensional imaging is a noninvasive objective assessment tool that identifies specific areas of the face responsible for asymmetry. Facial curve analysis describes the face more comprehensively and characterizes soft tissue contours.
