High-frequency Ultrasound in the Assessment before and after Applying HArmonyCa™.

Aim: To describe a clinical case of ultrasound (US) used to evaluate, before, post-immediately, and after 4 months, the facial application of a volumizing and biostimulating substance.

Background: Detecting the behavior of injected filler materials with high-frequency US-guided application is the future of natural facial rejuvenation with more predictable and satisfactory results.

Technique: A patient indicated for orofacial harmonization (OFH) procedures through volumizing and biostimulating material application was invited to participate.

Choosing Juvéderm Volux™ to chin augmentation: Case report and flowchart for clinical evaluation.

Introduction: The development of filler biomaterials with high hyaluronic acid concentrations, cohesiveness, and elastic modulus has become an option for chin augmentation, as the balance of these rheological properties promotes high lifting capacity, providing minimally invasive perceptible improvements in patient appearance.

Presentation Of Case: The present study reviewed clinical and anatomical aspects of patients referred for chin augmentation and created a flowchart to assertively diagnose patients with an indication of Juvéderm® Volux™ for defining the lower third of the face.

Discussion: The chin is vital for facial proportions and attractiveness perception.

Mandibular metastasis of primary extrahepatic biliary carcinoma: Case report.

Introduction And Importance: Cholangiocarcinoma is a malignant neoplasm with a difficult diagnosis and unfavorable prognosis that can appear anywhere in the biliary tree. Anatomically, it can be classified as intra- or extrahepatic, the latter being the most common primary malignancy of the biliary tract. Although bone tissue is the third most common target for metastases in general, metastatic lesions from cholangiocarcinomas are uncommon in the head and neck.

Low-level Laser Therapy in the Management of Oral Mucositis Induced by Radiotherapy: A Randomized Double-blind Clinical Trial.

Aim: The present study evaluated the effect of LLLT at red and infrared wavelengths associated with therapeutic measures from the Mucositis Study Group of the Multinational Association of Supportive Care of Cancer and International Society of Oral Oncology (MASCC/ISOO) for preventing and treating RT-induced oral mucositis (OM).

Materials And Methods: For the study, 80 subjects diagnosed with head and neck cancer (HNC) undergoing treatment were randomized into three groups to apply different photobiomodulation protocols for 42 days, as follows: Group I-LLLT of 660 nm; Group II-LLLT of 810 nm; and Group III-association of wavelengths of 660 and 810 nm. The treatments were performed by properly trained professionals and with equipment calibrated for the intervention.

Orthognathic surgery and orthodontics associated with orofacial harmonization: Case report.

Introduction And Importance: Orthognathic surgery aims to restore the functional and esthetic standards of the face and non-surgical or minimally invasive procedures have been optimizing the results of facial orthosurgical treatments. This case report aimed to show the use of minimally invasive techniques that, associated with orthognathic surgery, represent a trend in current oral and maxillofacial rehabilitation.

Case Presentation: A female patient, 28 years old, white, sought care from the Dentistry team of the São Vicente de Paulo Hospital, in Passo Fundo, Brazil, complaining of mandibular prognathism, anteroposterior maxillary deficiency, dental crowding, malocclusion, functional and esthetic changes that negatively affected her psychosocial interactions and stomatognathic function.

The effect of laser and botulinum toxin in the treatment of myofascial pain and mouth opening: A randomized clinical trial.

This study conducted a randomized clinical trial in 15 patients, who sought care at the Dental Clinic of the University of Passo Fundo, in order to compare the use of low-level laser and botulinum toxin in the treatment of myofascial pain and whether they alter the mouth opening of patients with temporomandibular disorder. The patients were divided into two groups: the Laser group received low-level GaAlAs laser, 100mW of power at a wavelength of 830nm in continuous light emission; and the Toxin group received 30U of botulinum toxin type A (BTX-A) in the first session, and 15U after fifteen days. The assessments were performed by measuring pain with Visual Analogue Scale (VAS), and mouth opening with a digital caliper.

Effect of different photoactivation techniques on the bond strength of a dental composite.

Using the push-out test, this study evaluated the bond strength of the composite resin Z250 (3M/ESPE) photoactivated with the XL2500 (3M/ESPE) quartz-tungsten-halogen light-curing unit with different curing protocols: soft-start (150 mW/cm² for 2 s (S2), 3 s (S3), 5 s (S5), 10 s (S10) or 15 s (S15), followed by 700 mW/cm² for 15 s; pulse-delay (150 mW/cm² for 2 s (P2), 3 s (P3), 5 s (P5), 10 s (P10) or 15 s (P15), with a 1-min delay, followed by 700 mW/cm² for 15 s. After storage at 37°C ± 1 for 24 h ± 1, the specimens were ground, polished and subjected to a push-out test in a universal test machine (Instron) with a cell load of 500 N at a crosshead speed of 0.5 mm/min.

Effect of different initial light intensity by the soft-start photoactivation on the bond strength and Knoop hardness of a dental composite.

This study evaluated the bond strength (push-out method) and Knoop hardness of Z250 composite resin, photoactivated with XL 2500 curing unit, using different protocols: continuous mode (700 mW/cm(2) for 20s) (CO); soft-start (50 mW/cm(2) for 5 s, followed by 700 mW/cm(2) for 15 s) (SS1); soft-start (100 mW/cm(2) for 5 s, followed by 700 mW/cm(2) for 15 s) (SS2); soft-start (150 mW/cm(2) for 5 s, followed by 700 mW/cm(2) for 15s) (SS3); soft-start (200 mW/cm(2) for 5s, followed by 700 mW/cm(2) for 15s) (SS4); soft-start (250 mW/cm(2) for 5 s, followed by 700 mW/cm(2) for 15 s) (SS5); soft-start (300 mW/cm(2) for 5 s, followed by 700 mW/cm(2) for 15 s) (SS6). For the push-out test, the specimens were tested in a universal testing machine at a crosshead speed of 0.5 mm/min.
