Halitosis can be described as unpleasant odors emanating from the oral cavity. It is usually associated with decomposition action of bacteria present mainly on the back of the tongue and periodontal pockets, and able to produce volatile sulfur compounds. We conducted a study at the Faculty of Dentistry, Federal University of Juiz de Fora and evaluated the therapeutic effect of two natural extracts, Camellia sinensis (green tea) and resveratrol in the form of oral polymer films, to control halitosis.

Background: Resveratrol is a polyphenol that has gained momentum in therapeutics in the last few years.

Objective: In this study, we hypothesised that resveratrol could act prophylactically and/or treat inflammatory lesions of the oral cavity after being delivered by two different formulations of buccal mucoadhesive tablets (F1 and F2, which differed in terms of viscosity agents used).

Methods: This hypothesis was assessed through permeation studies, to verify diffusion of the drug through the buccal mucosa using a porcine model to predict human in vivo behaviour.

This case report describes the surgical removal of cementoblastoma associated with apicoectomy and endodontic therapy. The patient, an 18-year-old man, presented pain in the region of the mandibular body on the right side. On clinical exam, bone expansion was observed in the region at the bottom of the vestibular sulcus, pain on palpation, slight extrusion of tooth 46 with presence of pulp vitality.

The pseudoxanthoma elasticum is a multisystemic heritable disease that primarily affects the connective tissue. It has been characterized by fragmentation and calcification of elastic fibers that can lead to complications of skin and cardiovascular system and changes in retina. Involvement of the oral mucosa has been described like white patches striated especially in the mucosa of both upper and lower lips.

This study evaluated the effectiveness of the essential oil of Pimenta pseudocaryophyllus in inhibiting the growth of the main bacteria responsible for bad perspiration odor (Staphylococcus epidermidis, Proteus hauseri, Micrococcus yunnanensis and Corynebacterium xerosis). The chemical profile of the essential oil was evaluated by high-resolution gas chromatography (HR-GC) and four constituents were identified, eugenol being the major component (88.6%).

Objective: This research aimed at comparing the qualitative chemical compositions and the surface morphology of fracture regions of eight types of Nickel/Titanium (NiTi) conventional wires, superelastic and heat-activated (GAC, TP, Ormco, Masel, Morelli and Unitek), to the wires with addition of copper (CuNiTi 27ºC and 35ºC, Ormco) after traction test.

Methods: The analyses were performed in a scanning electronic microscope (JEOL, model JSM-5800 LV) with EDS system of microanalysis (energy dispersive spectroscopy).

Results: The results showed that NiTi wires presented Ni and Ti as the main elements of the alloy with minimum differences in their composition.

Oral lichen planus (OLP) is considered a chronic autoimmune inflammatory disease and its presence may be related to increased emotional stress. The clinical relevance of OLP is the possibility of developing a squamous cell carcinoma, the etiology of which is still unknown. The aim of this study is to treat OLP lesions resistant to conventional treatment with corticosteroids, using topical tacrolimus 0.

This paper describes the autologous transplantation of a mandibular right third molar to replace the residual roots of the second molar in the same quadrant, preserving function and aesthetics. A 5-year clinical and radiographic follow-up was undertaken. After transplantation, the donor tooth received endodontic treatment and placement of calcium hydroxide, which was periodically replaced every 3 months until the filling of the root canals, totalizing a period of 1-year, when apical closure was confirmed.

Objective: To evaluate and compare "in vitro" the maximum friction force generated by three types of esthetic brackets, two types of polycrystalline conventional ceramic brackets (20/40 and InVu) and one type of sapphire monocrystalline bracket (Radiance) in dry and artificial saliva wet settings. Also, to evaluate the influence exerted by artificial saliva on the friction forces of those brackets.

Methods: Tests were performed in dry and artificial saliva wet setting (Oral Balance) by using an EMIC DL 10000 testing machine, simulating a 2 mm slide of 0.

Purpose: To assess the long-term behavior of wedge-shaped implants and evaluate the influence of the associated risk factors on implant survival rates.

Materials And Methods: A retrospective review of clinical records of patients treated with wedge-shaped implants between 1992 and 2011 was conducted. Data on patient sex, age, smoking habits, and history of periodontitis; details of implant length, diameter, angle, and location; and data on surgical, reconstructive, and prosthetic procedures, and systemic disease were selected for analysis.

Objective: To identify the overall survival and prognostic factors of malignant lymphoma of the oral cavity and the maxillofacial region.

Study Design: Clinical records data were obtained in order to determine overall survival at 2 and 5 years, the individual survival percentage of each possible prognostic factor with the actuarial technique, and the survival regarding the possible prognostic factors with the actuarial technique and the Log-rank and Cox's regression tests.

Results: Of 151 subjects, an overall survival was 60% at 2 years, and 45% at 5 years.

Introduction: Recent studies have identified periodontal disease (PD) as a risk factor for chronic kidney disease (CKD). The aim of this study was to assess the general knowledge about, attitudes toward, and behaviors/practices concerning PD among physicians and nurses who work with CKD patients.

Methods: An 8-question questionnaire was distributed to participants of the XXV Brazilian Congress of Nephrology (2010) and the Minas Gerais Nephrology Congress (2011).

Patients with Down syndrome may not be cooperative during dental treatment and, in cases of complex treatment, it is necessary to use oral or inhaled sedation and/or general anesthesia, which represent safe and efficient treatment resources. There are few reports about oral rehabilitation with dental implants in patients with Down syndrome in the literature. This paper presents the case of a patient with Down syndrome and moderate mental retardation who suffered avulsion of the maxillary left central incisor after a fall, and was treated by means of a single dental implant with immediate load carried out under general anesthesia.

Ankylosis of the temporomandibular joint (TMJ) can be a result of several causes such as trauma, degenerative changes, infection, and space-occupying lesion. When occurring during early childhood, it can result in severe functional disability and facial deformity. Septic arthritis is an uncommon disease associated with systemic and local factors being most commonly caused by Staphylococcus aureus, Neisseria gonorrhoeae, and Haemophilus influenzae.
