Lesão Cervical não cariosa: uma abordagem clínica e terapêutica / Non-carious cervical injury: a clinical and therapeutic approach

As lesões cervicais não-cariosas (LCNCs) são problemas frequentes nos consultórios odontológicos. Possuem etiologia multifatorial e se caracterizam pela perda de esmalte na região cervical dos dentes, causando deficiência tanto funcional, quanto estética. Como consequência dessas lesões, existe a hipersensibilidade dentária, causada pela presença de fluídos no interior dos túbulos dentinários que atingem as terminações nervosas. Nesse sentido, o objetivo desta revisão de literatura foi realizar uma abordagem acerca das LCNCs, evidenciando os fatores etiológicos, suas consequências e a importância do correto diagnóstico e remoção do agente causador para a realização dos diferentes métodos de tratamentos. Diante dessa realidade, o tratamento varia de acordo com o diagnóstico do aparecimento dessas lesões, sejam elas causadas por fatores intrínsecos ou extrínsecos ou a união de ambos. Sendo de fundamental importância o controle dos mesmos para o sucesso do tratamento e uma maior longevidade das estruturas dentárias.

Non-Carious Cervical Injuries (NCCIs) are frequent problems in dental offices. They have a multifactorial etiology and are characterized by the loss of enamel in the cervical region of the teeth, causing both functional and aesthetic deficiencies. Because of these injuries, there is tooth hypersensitivity, caused by the presence of fluids inside the dentinal tubules that reach nerve endings. In this sense, the objective of this literature review was to conduct an approach about NCCI, highlighting the etiological factors, their consequences and the importance of the correct diagnosis and removal of the causative agent for the realization of the different treatment methods. In view of this reality, treatment varies according to the diagnosis of the appearance of these lesions, whether they are caused by intrinsic or extrinsic factors or the union of both. Being of fundamental importance the control of the same for the success of the treatment and a greater longevity of the dental structures.

Methods: After approval by the Ethics Committee on Research with Human Beings, the assessment was conducted through a questionnaire composed of 10 questions about the appearance of the Dental Surgeons. The interviewee assessed the degree of importance of the items, assigning a score from 0 to 10, 0 being considered terrible, and 10 excellent. Descriptive statistics procedures were used to express the results such as mean, median, standard deviation (SD), interquartile range (AIQ), and frequencies (relative and absolute). The significance level adopted was 5% (p-value 0,5) Results: According to the students' perception, the time since graduation and the professional profile in the social media influence in the choice of the professional while using piercings is an aspect that contributes to a more negative perception of the professional. Conclusion: The appearance of the Dental Surgeon is a very important aspect used by undergraduate students to choose a professional.

Molecular detection of Hepatozoon felis in cats from Maio Island, Republic of Cape Verde and global distribution of feline hepatozoonosis.

BACKGROUND: Vector-borne diseases are emerging worldwide and have an important zoonotic relevance. In the last few years, the interest in vector-borne pathogens in cats has increased. However, studies on feline vector-borne pathogens on tropical islands are lacking. Islands differ from continental countries because they have an enclosed population of animals, with all year presence of the vectors and, most often, without vector control measures. This study focused on the molecular identification and phylogenetic analysis of vector-borne pathogens in autochthonous cats with a mixed indoor-outdoor lifestyle from Maio Island, Cape Verde archipelago. METHODS: Blood samples were collected from 80 asymptomatic cats, representing almost a quarter of the total cat population of the island. The presence of DNA of protozoa of the genus Hepatozoon and bacteria belonging to family Anaplasmataceae and to genus Bartonella was assessed by PCR and phylogenetic analysis was conducted. Statistical analysis was performed to identify risk factors associated with infection. For feline hepatozoonosis, a worldwide dataset of Hepatozoon felis sequences retrieved from mammal species and vectors along with Hepatozoon spp. sequences retrieved from felids was generated, phylogenetically analyzed and the geographical and host distribution was assessed. RESULTS: Hepatozoon felis genotype I was identified in 12 (15%) cats from Maio Island whereas none of the cats were PCR positive for the other pathogens tested. No significant association of H. felis infection with age, sex, location or presence of vectors was observed by statistical analysis in Cape Verde's cats. Phylogenetic analysis on the worldwide dataset of feline Hepatozoon sequences showed two significant distinct clades for H. felis genotype I and II. Different geographical distributions were assessed: H. felis genotype I was the only genotype found in Africa and has been reported worldwide, with the exception of Japan and Brazil where only H. felis genotype II has been reported. CONCLUSIONS: The identification of H. felis genotype I in cats in Maio Island highlights the need to further investigate the significance of H. felis genotypes and to clarify the epidemiological aspects of this infection.

The importance of immunological findings in the identification of head and neck pathological changes: A literature review

Introduction: Radiography serve as an aid for professional and is a primary factor in obtaining more accurate diagnoses, as well as immunological findings diagnosing diseases early. Objective: Given the importance of these tests, this paper aims to analyze the importance of imaging findings in the identification of pathological changes of the head and neck. Methodology: For this, a literature review based on literature by consulting the scientific articles selected by searching the PubMed database was performed, Lilacs and Bireme, besides the assets of the College Northeast Independent Library. Being selected 26 articles, of the last 15 years that had relation with the subject approached. Discussion: Dentists should have an overview of the maxillofacial structures, and to identify changes not directly related to dentistry, which further enhances its utility and indication for other operating areas. Conclusion: This professional has the ability to identify changes to the head-neck complex views on radiographs and the duty to refer these patients to a specific medical treatment preventing possible complications.

Prevalence and diversity of Hepatozoon in native and exotic geckos from Brazil.

Hepatozoon is a genus of hemogregarines constituting the most widespread and common reptile hemoparasite. Although various molecular assessments of these parasites have been conducted in lizards from Africa and Europe, similar studies are needed for South American lizards. Through amplification and sequencing of fragments of the 18S rRNA gene, we assess the prevalence of Hepatozoon parasites in 230 geckos from South America, including the endemic species Hemidactylus agrius, Hemidactylus brasilianus, Lygodactylus klugei, Phyllopezus pollicaris, Phyllopezus periosus, and an exotic species, Hemidactylus mabouia . We found an overall low prevalence of Hepatozoon infection (7/230, 3%) with only 3 of the 6 host species infected with Hepatozoon ( Hemidactylus mabouia , P. pollicaris, and P. periosus). Within the 7 infected host samples, 5 genetically distinct lineages of Hepatozoon parasites were identified, only 1 of which was similar to previously published haplotypes. Thus, although prevalence is low, genetically based diversity of Hepatozoon in geckos from South America is very high. Three of these lineages appear basal to 1 of the major clades of Hepatozoon, suggesting that this clade might have originated in South America, and thereby indicating a potential phylogeographic pattern that had not been previously identified. Future studies should assess the distribution and competence of invertebrate hosts in the regions analyzed, and Hepatozoon diversity in other less well-known regions of the world.
