The present study results link the systemic effects of induced periodontitis with changes in hepatic tissues such as microvesicular steatosis, likely caused by an increase in oxidative stress and lipid peroxidation. The findings from the present study implicate an association between a decrease of pericytes and liver disease caused by ligature-induced periodontitis in rats.

Objective. The aim of this systematic review was to investigate the advances in the study of medicinal plants and their biologic effects on periodontitis in animal models. Study Design. A systematic search was conducted by three independent researchers, who screened articles published up to March/2016, to identify the studies that contained sufficient and clear information on the association of the medicinal plants and periodontitis in murine models. The searches were performed using PubMed, Cochrane, and Science Direct databases. Results. After a critical analysis of titles and abstracts, 30 studies were finally eligible for analysis. The studies presented a great diversity of the experiment designed regarding the methods of induced periodontitis and the evaluation of the medicinal plants efficacy. None of the studies described the possible toxic effects associated with the administration of the plant material to animals and whether they could prevent damage to organs caused by systemic effect of induced periodontitis. Gel-based formulations containing plant substances are seen as an interesting strategy to treat periodontitis. Conclusions. In this systematic review, the state-of-the-art knowledge on the medicinal plants and the induced periodontitis was critically evaluated and discussed from the experiment designed to the possible clinical application.

Ectodermal dysplasia (ED) is a genetically heterogeneous condition resulting from clinical anomalies of structures derived from the ectoderm, such as the hair, nails, sweat glands, and teeth. This clinical report presents the case of a child diagnosed with hypohidrotic ED at 2 years of age; clinical and imaging evaluation was performed with 6-year follow-up, and we present details of the prosthetic dental care, with a 12-month follow-up. The patient's masticatory capacity had improved, leading to the child gaining 4 kg. In conclusion, prosthetic management was noninvasive and appeared to lead to developmental benefits for the patient.

<p><strong>Objective: </strong>The aim of the study was to evaluate the frequency of distal caries in the second molar influenced by the angulation of the third molar adjacent on panoramic radiographs in a clinical dental radiology. <strong>Material and</strong><strong> Methods: </strong>A descriptive and quantitative study that examined 750 panoramic radiographs, of this total, 120 were in accordance with the inclusion criteria of the study was conducted.<strong> Results: </strong>157 seconds and third molars analyzed the prevalence of caries in the distal of the second molar was 25.5%. The most prevalent angle position of the third molar was 57.3% with the vertical, but the position with the highest percentage of decayed molar second distal mesioangular was 50% of the cases. The elements listed, males obtained 40% of second molar distal caries versus 17% for females. People aged 35 or older had the highest incidence with 50% distal caries while other bands obtained 16.21% in the group 18-24 years, and 23.52% in 25-34 years. <strong> Conclusion: </strong>It was possible to establish a sliding scale on the indication for prophylactic removal of mandibular third molar according to the angulation of Winter: horizontal, mesioangular, vertical and distoangular. One can also see a greater relevance to the indication of prophylactic removal of male individuals aged over 35 years.</p>

<p>Magnetic resonance imaging (MRI) is a type of imaging study considered the gold standard in the analysis of the internal structure and content of intraosseous lesions, allowing for their inherent characteristics of acquisition, determine the nature and differential diagnosis between changes that have aspects Similar to other imaging modalities, such as on radiographs and computed tomography (CT) and also has the great advantage of not being an invasive method, since it does not use ionizing radiation.The ultrasound (U.S.) and MRI provides images without showing deleterious effects to living organisms, enabling the differentiation between solid and cystic lesions, however, lacks the ability of MRI to provide an anatomical detailing determined, nor information about the chemical composition of the lesions, which would be crucial in determining the diagnosis of the same. The dentigerous cyst is among the most frequent odontogenic lesions that affect the maxillomandibular complex, requiring a thorough assessment of its extent and proximity to anatomical structures as well as the differential diagnosis with other lesions. This study aimed to emphasize the use of MRI and U.S. in the diagnosis of lesions dentomaxilofaciais, describing a clinical case of dentigerous cyst in these imaging modalities were used as complementary tests.<strong></strong></p>

Objective: To conduct a retrospective study through epidemiological survey of the biopsies of oral cavity performed at the Center of Pathology, Cytology, and Cytopathology– CEPACC in Parnaíba-PI, from 1998 to 2011. Material and Methods: One hundred and thirty-nine referrals and reports were analyzed by evaluating the group and prevalence of oral lesions, anatomical location, and distribution in relation to type, gender, and age. Results: Females (52%) showed the greatest prevalence, observing more cases in the age range of 41 to 60 years. The lip was the preferable location of the analyzed lesions. The groups of the lesions in salivary glands (17%), malignant tumors of epithelial origin, benign tumors of conjunctive origin, premalignant lesions of epithelial origin, and odontogenic cysts were the most common lesions. Considering the isolated lesions, squamous cell carcinoma was the most frequent. We observed a greater preference for salivary gland lesions, although great diversity of clinical cases was found. Conclusion: The reported lesions occurred mostly in adult females and in groups with salivary gland diseases. KeywordsEpidemiology; Oral lesions; Biopsy; Oral Pathology; Diagnosis.
