When educators adopt flipped learning in their courses, online sources are assigned for students to study prior to class, and then the class period is devoted to face‐to‐face (F2F) interactions. The aims of this systematic review were to evaluate published research on the effectiveness of flipped learning for dental students' learning and on dental students' perceptions of the model and to report the results based on the first two phases of Kirkpatrick's model: reaction and learning. A systematic review based on the Preferred Reporting Items for Systematic Reviews and Meta‐Analysis Protocols (PRISMA‐P) was performed. Articles in which the objective was to determine the effectiveness of students' learning or students' perceptions of flipped learning in both dental and advanced dental education were collected. The Risk of Bias of the included studies was assessed using the MINORS Grading of Recommendations Assessment, Development, and Evaluation (GRADE) Summary of Findings table. The authors screened the title and abstract of 650 studies; after application of inclusion criteria, eight articles remained for analysis. In those studies, a total of 572 dental students were participants. The effectiveness of flipped learning and conventional lectures was compared in five of the eight studies; three of the studies compared students' perceptions of flipped learning and the conventional format; and four of the studies assessed students' perceptions of flipped learning without comparison to another methodology. The findings suggest that flipped learning was an effective way to deliver knowledge in these eight studies. Time flexibility was a particular asset found in this review since flipped learning allowed each student to assimilate the educational material at her or his own pace.

Introduction: Patients presenting Temporomandibular Disorders (TMD) are common in our daily clinical practice. One of the possible conditions that lead to TMD is the habitual chewing side syndrome. Methods: In this case report a clinical approach is presented to manage the TMD related to unilateral vicious mastication. A 42 years old woman presented reporting headaches, difficulty to open mouth, presence of sensitivity in the left ear and TMJ region, soreness on the left side temporal region and sensitivity in the anterior inferior teeth. It was noted that the patient habitually clenched and ground teeth. Patient mentioned chew more on the left side. Results: After confirming the unilateral mastication, a modified therapy based on the Neuro occlusal Rehabilitation was applied through the use of a splint. After 60 days the patient described absence of the previous symptoms and pain relief. Conclusion: The evaluation of the masticatory pattern is often neglected; however, it is of great importance since it can lead to several conditions such as condyle wear, pain, alteration of the occlusal plane, deviation of the medial line, deviation of the mandible at mouth opening, bone alterations, Temporomandibular joint (TMJ) hypofunction, headache, among others.

Objective: Although dentists have an important role related to sleep disorders, there is a concern about how far dentists can go when screening or treating these patients. The objective of this systematic review is to present guidelines, recommendations, and studies designed with the intention to describe and guide the role of dentists in sleep-disordered breathing (SDB)-related issues. 1 Methods: The eligibility criteria were guidelines, protocols, and recommendations focused on determining the role of dentists in the sleep disorders topic. The search was conducted through the databases Cochrane, EMBASE, Medline, LILACS, PubMed, and Web of Science. This systematic review was reported according to the preferred reporting items for systematic review and meta-analysis protocols (PRISMA). 1 Results: Overall, a total of 1,432 studies were found in the 6 databases searched. After removing duplicates, the studies were evaluated by title and abstract. In the second phase, 231 studies were evaluated by reading their full text. Twenty-two studies matched the inclusion criteria. Conclusions: Through this systematic review it is possible to conclude that the guidelines describe the role of dentists in screening patients for SDB/obstructive sleep apnea (OSA) as follows: refer the patients suspected of SDB/OSA to sleep physicians; apply, manage, and follow up the use of oral appliances. Clinical significance: All dentists should screen for SDB/OSA; however, only well-trained dentists with good knowledge of dental sleep medicine should be part of the multidisciplinary team to treat patients with SBD/OSA.

The purpose of this study was to evaluate and compare dental and skeletal changes associated with the Damon and Rapid Maxillary Expander (RME) expansion using Cone-Beam Computed Tomography (CBCT). Eighty-two patients, from The University of Alberta Orthodontic Clinic, were randomly allocated to either Group A or B. Patients in Group A received orthodontic treatment using the Damon brackets. Patients in Group B received treatment using the Hyrax (a type of RME) appliance. CBCT images were taken two times (baseline and after expansion). The AVIZO software was used to locate 18 landmarks (dental and skeletal) on sagittal, axial, and coronal slices of CBCT images. Comparison between two groups showed that transverse movement of maxillary first molars and premolars was much greater in the Hyrax group. The lateral movements of posterior teeth were associated with buccal tipping of crowns. No clinically significant difference in the vertical or anteroposterior direction between the two groups was noted. Alveolar bone next to root apex of maxillary first premolar and molar teeth showed clinically significant lateral movement in the Hyrax group only. The comparison between two groups showed significantly greater transverse expansion of the first molar and first premolars with buccal tipping in the RME group.
