Effect of treatment of transverse maxillary deficiency using rapid palatal expansion on oral health-related quality of life in children: complementary results for a controlled clinical trial.

Objective: To evaluate the effect of rapid palatal expansion (RPE) using Haas-type expanders on children's oral health-related quality of life (OHRQOL) and compare said effect with that previously reported for the use of Hyrax-type expanders.

Materials And Methods: Forty participants aged 8-10 years with transverse maxillary deficiency were treated using Haas appliances. OHRQOL was measured using the CPQ before RPE, during RPE (T), at the end of RPE (T), and 1 month after appliance removal (T).

Peeling with retinoic acid in microemulsion for treatment of melasma: A double-blind randomized controlled clinical study.

Objective: To evaluate the clinical efficacy of peeling with a microemulsion formulation containing 1% retinoic acid.

Materials And Methods: After development of the product, 60 patients with melasma were randomly divided into three groups (n = 20): Group 1-application of conventional 1% retinoic acid peeling (RA 1%). Group 2-application of 1% retinoic acid peeling in microemulsion (RA 1%M).

Does dental trauma and its consequences influence the professional hiring process? Development, validation and application of an assessment tool.

Objectives: To develop and validate a questionnaire concerning the aspects evaluated during the hiring process by human resources professionals (HRPs); to apply the validated questionnaire; and to evaluate the perceptions and judgment of HRPs regarding different traumatic dental injuries (TDIs) and their consequences (TDI-Cs).

Materials And Methods: The acceptability, discriminative properties, internal consistency and test-retest reliability of the developed questionnaire were evaluated, using the same methodology as the main study and adopting a pilot sample. For both the validation process and the application phase, images of one male and one female were manipulated, or not (control), to create different types of TDI (enamel fracture, enamel and dentin fracture, avulsion) and TDI-Cs (crown discoloration, tooth loss due to avulsion).

Impact of Orthognathic Correction of Class II Malocclusion on the Perception of Social Characteristics.

Objective: To evaluate the influence on the perception of social characteristics after orthognathic treatment for the correction of Class II malocclusion.

Methods: A cross-sectional study was conducted with the participation of 240 observers who evaluated images of individuals before and after orthognathic surgery for the correction of malocclusion. Based on the images, two different questionnaires were applied containing 44 questions each for evaluating social competence, intellectual ability, psychological adjustment, and attractiveness.

Do you know this syndrome? Leopard syndrome.

Hypertrophic cardiomyopathy is known as Leopard syndrome, which is a mnemonic rule for multiple lentigines (L), electrocardiographic conduction abnormalities (E), ocular hypertelorism (O), pulmonary stenosis (P), abnormalities of genitalia (A), retardation of growth (R), and deafness (D). We report the case of a 12-year-old patient with some of the abovementioned characteristics: hypertelorism, macroglossia, lentigines, hypospadias, cryptorchidism, subaortic stenosis, growth retardation, and hearing impairment. Due to this set of symptoms, we diagnosed Leopard syndrome.

Clouston syndrome associated with eccrine syringofibroadenoma.

Eccrine syringofibroadenoma is a rare benign neoplasia derived from acrosyryngium cells of the eccrine sudoriferous glands. It affects the extremities of elderly individuals as solitary tumors, or may also present as multiple lesions. There are controversies about the pathogenesis and differentiation of the tumor.

Craniofacial features of patients with sickle cell anemia and sickle cell trait.

Objective: To identify the craniofacial characteristics of patients with sickle cell trait (SCT) and sickle cell anemia (SCA) and to compare these measurements with those of nonaffected subjects.

Materials And Methods: Clinically normal patients and those with SCT and SCA were evaluated in this study. The patients were divided into three groups: normal (control), SCA, and SCT (n  =  with 15 in each group).

Pityrosporum folliculitis in an immunocompetent patient: clinical case description.

The present report concerns Malassezia-related pityrosporum folliculitis in a patient without any predisposing factor. Once the diagnosis had been confirmed by histopathologic exam, the patient was treated with oral ketoconazole and selenium sulfide shampoo; complete remission of the clinical condition was obtained. Thus it could be concluded that in spite of being routinely associated with immunosuppression, this condition may be present in an immunocompetent patient.

Perception of the esthetic impact of gingival smile on laypersons, dental professionals, and dental students.

Objective: The aim of this study was to evaluate perceptions regarding esthetic appearance of the smile in cases of orthognathic surgery for correction of maxillary gingival display.

Study Design: Alterations were made to an extraoral front-view photograph of a gingival smile in normal occlusion by repositioning the maxilla to simulate bone tissue removal and gingival exposure. Images were printed on photographic paper attached to questionnaires distributed among laypersons, professionals, and dental students to evaluate degree of esthetics (n = 150).

Facial lipodystrophy in an HIV-positive patient using an orthodontic appliance.

The aim of this article was to relate the clinical case of an HIV-positive orthodontic patient who reported that her cheeks had been hurting since treatment began. We started with the data collected in anamnesis and by contact with the patient's physician, and a diagnosis of facial lipodystrophy as a result of the use of retroviral drugs was reached. The patient was referred to a dermatologist for treatment of the facial lipodystrophy.

Sturge-Weber syndrome in an orthodontic patient.

The aim of this article was to describe the Sturge-Weber syndrome in a patient with orthodontic requirements. Pathologies involved in this syndrome affect facial cranial growth.

IINFLUENCE OF THE IMMUNOSUPPRESSANT TACROLIMUS (FK-506) ON THE FLEXURAL STRENGTH OF FEMUR: A STUDY IN RATS.

Objective: To evaluate the resistance to femoral fractures among rats treated with the immunosuppressant tacrolimus FK-506 and compare these to untreated rats and rats treated with placebo.

Methods: Ninety male Wistar rats were used. The animals were nine weeks old and weighed between 220 g and 280 g.
