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.
