    Ectopic teeth in maxillary sinus is rare and are usually removed via sub-labial trans-canine fossa approach (SLCFA). The aim of our study was to present our experience with extraction of ectopic teeth in the maxillary sinus via transnasal endoscopic approach (TEA).

    Rhinologists were asked to share their experience in the management of ectopic teeth in the maxillary sinus. Data were reviewed retrospectively.

    Eleven cases were reported in 10 patients from 2010 to 2019, six males and four females with a mean age of 33.5 +/-17 years (range 16 to 61). Seven patients complained of sinonasal symptoms, two were diagnosed incidentally during routine dental work-up, and one had oro-antral fistula. In eight patients, a cyst coexisted within the maxillary sinus. Teeth were located arbitrarily within the sinus. All cases were operated by TEA. One patient had self-limited periorbital emphysema, one had transient cheek numbness, and one had early post-operative bleeding that stopped after endoscopic cauterization. Long-term follow-up revealed good clinical outcomes.

    Transnasal endoscopic removal of ectopic teeth from the maxillary sinus is a feasible and rational approach when SLCFA is contraindicated.

    There are several brands of fluoride varnishes in the market, but the dynamics of fluoride release from each one might be different. The purpose of this study was to evaluate in vitro the release of fluorides by fluoride varnishes and to determine the correlation with viscosity and wettability.

    Forty four enamel blocks 5×5 mm were randomly divided into 4 groups (n=11) ((Duraphat®, Clinpro™ White Varnish, Flúor Protector® and control). We applied 30 milligrams of fluoride varnish to each specimen. The specimens were immersed in a Calcium Phosphate solution at a pH= 6.0. We evaluated the release of fluoride, by using a selective fluoride electrode, during 6 weeks. Viscosity was measured using an Oswald Viscosimeter and the wettability was determined by measuring the contact angle between the varnish and the enamel slab. The statistical analysis was performed using Analysis of variance.

    Duraphat showed the highest fluoride release from the second weekend beyond (

    <0.001) and Clinpro the greatest rate of release. Duraphat release was the steadiest throughout the experiment. Duraphat showed the highest viscosity and the lowest wettability (

    <0.001) and Fluor Protector showed the highest wettability (

    <0.001). There was a positive correlation between the release of fluoride and the viscosity and a negative correlation between fluoride release and wettability (r>0.7).

    Viscosity and wettability influence the release of fluoride from fluoride varnishes.

    Zygomatic complex fracture is second most common mid face fracture and frequent amongst the maxillofacial trauma. Fracture pattern ranges from simple to comminuted and from minimally displaced to severely displaced depending on various factors.

    98 patients with zygomaticomaxillary complex fracture reporting during December 2017 to January 2020 were included in the study. On the basis of radiographic evaluation and computerized tomography scan (CT scan) with 3D reconstruction severity of fracture was assessed and different treatment options were selected.

    Road traffic accident accounted as the leading cause of fracture (57.1%) followed by self-fall (16.3%), interpersonal violence (12.3%). Reduction and semi rigid fixation was done in (83.7%), in which 1-point fixation in (22.9%), 2-point fixation in (42.4%) and 3-point fixation in (18.4%). Rest 16.3 % of the cases were managed conservatively since they had minimal displacement.

    Road traffic incident was the main etiology in our study and younger age group patients were more involved. Occipitomental radiograph and computerized tomography scan (CT scan) were used to confirm the diagnosis and to determine the severity of displacement of zygomatic fracture on the basis of which treatment options were decided.

    Closed-loop communication (CLC) is associated with decreased medical errors and improved time-to-task completion during resuscitations. Zongertinib in vivo Depriving team leaders of sight during training may accelerate the acquisition of favorable communication skills; however, its effect on the frequency of CLC is unclear, especially with trainees.

    We assessed the effect of depriving interns of sight during advanced cardiovascular life support (ACLS) on verbal communication patterns and resuscitation confidence.

    All interns undergoing ACLS training in June 2019 at a single center were eligible. Interns were randomized to blindfolded training (BT) or standard training (ST). BT team leaders were blindfolded during practice sessions and permitted to use sight during testing. Testing scenarios were video- and audio-recorded. Recordings were assessed for teams’ performance and communication patterns. Participants were surveyed for confidence with resuscitation skills before and after ACLS training.

    All 87 eligible interns participated in the study (100% participation).
