In mixed-dentition patients, what is the short-term effectiveness of functional appliances (FAs) compared to untreated controls on mandibular dimensions?
This Systematic Review Summary is adapted from the article published on the ADA Center for Evidence-Based Dentistry website: The effects of functional appliances on mandibular growth during mixed dentition are unlikely to be of clinical importance Read the full commentary Clinical Question In mixed-dentition patients, what is the short-term effectiveness of functional appliances (FAs) compared to untreated controls on mandibular dimensions? Main Results Four RCTs met the inclusion criteria (338 participants, of which 168 were in the treatment group and 170 in the control group). Heterogeneity in age, interventions, and outcomes were observed, and follow-up times ranged from 15 to 18 months. Two ...Read More »

This question was submitted by a general dentist: Why do I have to wash my hands, if I am wearing gloves? Dr. Nita Mazurat, representing the Organization for Safety, Asepsis, and Prevention (OSAP) has provided this quick initial response Hand hygiene is performed because hands are a potential source of contamination to the patient, when placing gloves or during treatment. Microorganisms grow exponentially in the warm moist environment of the glove. If a glove becomes compromised during treatment, there is more protection to the patient, if the hands have been washed and perhaps even more if they were washed using an antimicrobial ...Read More »
