Dentofacial deformities (DFD) presenting mainly as Class III malocclusions that require orthognathic surgery as a part of definitive treatment. Class III patients can have obvious signs such as increasing the chin projection and chin throat length, nasolabial folds, reverse overjet, and lack of upper lip support. However, Class III patients can present different facial patterns depending on the angulation of occlusal plane (OP), and only bite correction does not always lead to the improvement of the facial esthetic. We described two Class III patients with different clinical features and inclination of OP and had undergone different treatment planning based on 6 clinical features: (I) facial type; (II) upper incisor display at rest; (III) dental and gingival display on smile; (IV) soft tissue support; (V) chin projection; and (VI) lower lip projection. These patients were submitted to orthognathic surgery with different treatment plannings: a clockwise rotation and counterclockwise rotation of OP according to their facial features. The clinical features and OP inclination helped to define treatment planning by clockwise and counterclockwise rotations of the maxillomandibular complex, and two patients undergone to bimaxillary orthognathic surgery showed harmonic outcomes and stables after 2 years of follow-up.

Objective: This present study assessed the knowledge and clinical behaviors of dentists on antiresorptive medications (AM) and osteonecrosis of the jaws (ONJ). Methods: A cross-sectional study was performed by a questionnaire applied to a sample of 101 dentists. It inquired about general information, knowledge on AM and ONJ, behaviors regarding clinical cases of patients, and knowledge acquisition sources. Kappa coefficient (ƙ) checked the questionnaire’s reliability. Descriptive statistics were computed, Fisher’s test assessed the association between behaviors and knowledge. Logistic regression analysis to estimate propensity score. Statistical significance was set at p ≤ 0.05. Results: The reliability showed good agreement (ƙ = 0.8). 59% of the dentists reporting to know AM, 83% believing it is important to know whether patients took AM during anamnesis and 53% indicating that they knew that ONJ was a side effect of AM. However, 5% of the dentists informed that they could fully recognize brand name of AM, and that 50% would not perform any dental invasive treatment, with 73% acquiring knowledge on AM and ONJ from scientific articles. Conclusion: dentists recognized AM, but they would not be comfortable treating patients who had taken AM or developed ONJ. Educational efforts might be made to promote the knowledge of dentists.

To report one case of bleeding episodes after impacted teeth extractions had been performed in a patient with undiagnosed clotting disorder, describing a sequence of approaches for hemostasis up to the appropriated diagnosis and effective resolution. A male 16-year old patient with surgical indication to remove eight impacted teeth. After the surgery, there were bleeding episodes, being needed for hospital admission to keep on his physiological functions, blood pressure and heartbeat frequency regularly, to carry out laboratory blood tests, and to achieve hemostasis by using antifibrinolytics and blood products. After 24 hours, 11% of IX clotting factor was verified into bloodstream by specific blood test, being diagnosed with mild Hemophilia B. From the diagnosis, infusions of IX clotting factor were performed to the adequate resolution and recovery of the patient. The clinical conducts were efficient to keep on stable vital signs and achieving appropriate diagnosis. However, preventive behaviors should be applied in hemophilic patients in pre- or intra-operative, avoiding circumstances that can compromise health condition of the patient.
