How do we know a treatment is good enough? A survey of non-inferiority trials.

Background: Non-inferiority and equivalence trials aim to determine whether a new treatment is good enough (non-inferior) or as good as (equivalent to) another treatment. To inform the decision about non-inferiority or equivalence, a margin is used. We aimed to identify the current methods used to determine non-inferiority or equivalence margins, as well as the main challenges and suggestions from trialists.

Professional Development of Behavior Analysts in Europe: A Snapshot for 21 Countries.

Behavior analysts are not recognized or regulated as a distinct profession in Europe. For the most part, European behavior analysts adhered to the standards set by the U.S.

Risk prediction models for erosive wear in preschool-aged children: a prospective study.

Background: Despite increasing prevalence, age-specific risk predictive models for erosive tooth wear in preschool-age children have not been developed. Identification of at-risk groups and the timely introduction of behavioural change or treatment will stop the progression of erosive wear in the permanent dentition. This study aimed to identify age-specific risk factors for erosive wear.

Ulcerating nodules on a background of lower leg lymphoedema.

A patient presented with a 3-month history of a rapidly enlarging ulcerated tumour on his lower leg, occurring on a background of chronic idiopathic lymphoedema of approximately 10 years' duration. Histology revealed extensive infiltration of the dermis by a vascular tumour with pleomorphic and hyperchromatic endothelial cells, which stained positive for vascular markers CD31, CD34 and ERG. A diagnosis of lymphoedema-associated angiosarcoma was reached and our patient was treated with isolated limb perfusion with high-dose melphalan and tumour necrosis factor-alfa.

Dental Public Health in Action: Experiences and Responses of Oral Health Care Professionals during the First Wave of the COVID-19 Pandemic in Malta.

Initial impetus for action: Maltese Oral Health Care Professionals (OHCP) experienced changes to clinical practice and redeployment during the COVID-19 pandemic. In the early stages, there were few data on the resultant changes to the provision of dental services or their impact on the wellbeing of dental professionals. Solutions Suggested: Two questionnaires were designed to explore different domains in OHCP working on the frontline of the COVID-19 pandemic as well as in other areas/sectors.

Trueness, 3D Deviation, Time and Cost Comparisons Between Milled and 3D-Printed Resin Single Crowns.

The purpose of this in-vitro study was to compare trueness, 3D deviation, production time and costs of milled and 3D-printed resin single crowns. A total of 20 CAD-CAM resin single crowns were fabricated from 10 digital wax patterns designed on 10 tooth preparations available in a reference model. Standardized control linear measurements were performed with a CAD software.

Patient Reported Outcomes on Different Occlusal Schemes in Complete Denture Wearers.

Purpose: To compare patient-reported outcomes among balanced, lingualized, and monoplane occlusal schemes in relation to edentulous jaw classifications.

Materials And Methods: This randomized controlled trial was conducted in edentulous patients receiving new complete dentures using balanced, lingualized, or monoplane occlusal schemes. Demographic variables, bone ridge quantity, number of adjustments required after denture insertion, and satisfaction and quality of life (QoL) indices (ie, the Denture Satisfaction Questionnaire [DSQ] and General Oral Health Assessment Index [GOHAI], respectively) were assessed at 1, 2, 4, 8, 12, and 52 weeks.
