Clinical and radiographic outcomes of a two-piece ceramic implant: one year results from a prospective clinical trial.

OBJECTIVE: To describe the clinical and radiographic performance and survival rate of a new two-piece ceramic implant system after at least 12 months of follow-up. MATERIALS AND METHODS: Sixty-five implants were placed and followed up for at least 12 months (12.3 ± 1.5), in 50 patients. The implants were installed both in fresh extraction sockets and in healed sites and received provisional restoration when the clinical insertion torque was greater than 35Ncm. The primary results describe the survival rate of these implants. Clinical performance was evaluated through the evaluation of the Pink Esthetic Score (PES) and the degree of satisfaction of the patients. Bone loss was measured through radiographic measurements of the marginal bone loss in the mesial (MBLM) and distal (MBLD) sites. RESULTS: The survival rate was 98.5%. The average MBLM was 0.24 mm (± 0.53) and the MBLD was 0.27 mm (± 0.57). A statistical difference was observed only when comparing immediate implants with delayed ones (MBLM - p = 0.046 and MBLD - p = 0.028) and when they received immediate provisionalization or not (MBLM - p = 0.009 and MBLD - p = 0.040). The PES before the intervention (T0) was 13.4 (± 0.8) and the PES at T2 (12-month follow-up) was 12.9 (± 1.5) (p = 1.14). CONCLUSION: The new two-piece ceramic implant used in the present study showed predictable and reliable results, similar to those found with titanium implants after one year of follow-up. CLINICAL RELEVANCE: These implants can be used as an alternative to titanium implants in terms of the marginal bone loss and the degree of patient satisfaction.

Deciduous Molars Complexity Anatomy Reveled by Computed Microtomography.

OBJECTIVE: The aim of this study was to analyze the internal morphology of deciduous molars through the use of computed microtomography in a sample from Rio de Janeiro. MATERIAL AND METHODS: Thirty maxillary and 30 mandibular deciduous molars (n = 60), divided in first and second primary molars, were scanned by computed microtomography. The teeth were evaluated for root number, root canals, Vertucci classification, root curvature, presence of lateral canals, furcation dentin thickness, structure model index (SMI), volume, and canal surface area. RESULTS: The results showed 100% of maxillary molars had three roots and Vertucci type I canal was more prevalent in this group. In the mandibular ones, type IV was more frequent in the mesial root and class I in the distal root and the cavo-interradicular canal occurred in 2 specimens. Dentin thickness in the furcation region measured 1.53 and 1.59 mm in the maxillary and mandibular, respectively. Volume and area parameters varied according to the evaluated canals and SMI demonstrated that all canals had a cylindrical shape. CONCLUSION: More detailed information about the internal anatomy of the primary molars has been described, which may help strategies in the preparation of these root canals.

Aging as a Risk Factor on the Immunoexpression of Pro-Inflammatory IL-1ß, IL-6 and TNF-α Cytokines in Chronic Apical Periodontitis Lesions.

Persistent inflammatory responses in the elderly may act as modifiers on the progression and repair of chronic apical periodontitis lesions (CAPLs). While the involvement of IL-1ß, IL-6 and TNF-α in inflammatory responses and, particularly, in CAPL has been documented, their expression in elderly patients needs to be further characterized. Therefore, the purpose of this study was to evaluate and compare the expressions of pro-inflammatory cytokines in CAPL from elderly individuals with young/middle-aged individuals. Thirty CAPL (15 cysts and 15 granulomas) from elderly patients (>60 years) and 30 CAPL (15 cysts and 15 granuloma) from young/middle-aged individuals (20-56 years) were selected. Immunohistochemical reactions were performed against IL-1ß, IL-6 and TNF-α. The slides were subdivided into five high-magnification fields and analyzed. The number of positive stains was evaluated for each antibody. There was no significant difference between the cytokines when the cysts and granuloma were compared in the two groups. In the young/middle-aged, only IL-1ß showed a difference and was significantly higher in granulomas (p = 0.019). CAPL pro-inflammatory cytokine levels in the elderly were significantly higher than in young/middle-aged individuals (p < 0.05). The pro-inflammatory cytokines IL-1ß, IL-6 and TNF-α were significantly higher in CAPL in the elderly compared with the young/middle-aged group. Further elaborate research studies/analyses to elucidate the reasons for and consequences of inflammation in the elderly are recommended.

High-throughput nucleotide sequencing for bacteriome studies in oral squamous cell carcinoma: a systematic review.

PURPOSE: Dysbiosis has been identified in oral squamous cell carcinoma (OSCC). The aim of this study was to carry out a systematic review of an electronic research that was carried out on articles published between January 2008 and September 2018. METHODS: Eight studies were selected after applying the inclusion and exclusion criteria. RESULTS: All articles targeted the hypervariable regions of the 16S rRNA gene. At the phylum level, it was found reduction of Bacteroidetes (2/8 studies) and increase of Firmicutes (2/8 studies). At the genus level, Rothia increased (1/8 studies) and decreased (2/8 studies) in tumor samples, and Streptococcus also was found increased (3/8 studies) and reduced (3/8 studies). Fusobacterium only increased in OSCC samples (3/8 studies). At species level, an increase in F. nucleatum subsp. polymorphum was more associated to OSCC (2/8 studies) than with controls, as was P. aeruginosa (3/8 studies). CONCLUSION: In summary, the results corroborated dysbiosis in OSCC patients, with enrichment of microbial taxa that are associated with inflammation and production of acetaldehyde. However, variations of study design and sample size were observed among the studies, as well as a shortage of more detailed analyses of possible correlations between risk habits and OSCC. This lack of more detailed analysis may be the cause of the inconsistencies in regard of the alterations reported for certain genera and species. In conclusion, there is an association between OSCC and oral microbiota dysbiosis, but its role in oral carcinogenesis needs to be clarified in more detail.

High incidence of acquiring methicillin-resistant Staphylococcus aureus in Brazilian children with Atopic Dermatitis and associated risk factors.

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) colonization in Atopic Dermatitis (AD) patients can contribute to worsening their clinical condition. OBJECTIVE: A cohort study was carried out to determine the incidence of MRSA acquisition and its risk factors in AD children. METHODS: Patients with AD (2 months-14 years old) were followed up for about 1 year at a reference center for AD treatment in Rio de Janeiro, Brazil, from September 2011 to February 2014. Nasal swabs from patients and contacts were collected every 2 months. The SCORAD system assessed the severity of the AD. S. aureus isolates were evaluated to determine the methicillin resistance and the clonal lineages. RESULTS: Among 117 AD patients, 97 (82.9%) were already colonized with S. aureus and 26 (22.2%) had MRSA at the first evaluation. The incidence of MRSA acquisition in the cohort study was 27.47% (n = 25). The SCORAD assessments were: mild (46.15%), moderate (37.36%) or severe (16.48%). Risk factors were: colonized MRSA contacts (HR = 2.27; 95% CI: 1.16-7.54), use of cyclosporine (HR = 5.84; 95% CI: 1.70-19.98), moderate or severe AD (HR = 3.26; 95% CI: 1.13-9.37). Protective factors were: availability of running water (HR = 0.21; 95% CI: 0.049-0.96) and use of antihistamines (HR = 0.21; 95% IC: 0.64-0.75). MRSA isolates carried the SCCmec type IV and most of them were typed as USA800/ST5. CONCLUSIONS: The high incidence of MRSA acquisition found among AD patients and the risk factors associated show that an effective surveillance of MRSA colonization in these patients is needed.

CONHECIMENTO SOBRE BEIJO NA BOCA DE ADOLESCENTES DE UM GRUPO DE ESCOLAS PRIVADAS DE NOVA IGUAÇU/RIO DE JANEIRO ­ ESTUDO PILOTO / KNOWLEDGE ABOUT KISSING IN THE MOUTH OF ADOLESCENTS FROM A GROUP OF PRIVATE SCHOOLS IN NOVA IGUAÇU / RIO DE JANEIRO - PILOT STUDY

Objetivo: Descrever os conhecimentos sobre o beijo na boca e sua possibilidade de transmissão de doenças infecciosas em um grupo de adolescentes de escolas privadas de Nova Iguaçu/Rio de Janeiro, através deste estudo piloto. Metodologia: Estudo seccional em que foi aplicado um roteiro de perguntas semi-estruturado autoaplicável em adolescentes (de 18 e 19 anos) de ambos os gêneros, pertencentes a três escolas da rede de ensino privado do município de Nova Iguaçu no Estado do Rio de Janeiro. Resultados: De um total de 100 adolescentes que participaram deste estudo, mais da metade eram solteiros e do gênero feminino (61%), apenas estudantes como ocupação (88% do total) e 96% já haviam beijado na boca. A amostra selecionada demonstrou características próprias, com a alta frequência do conhecimento da possibilidade de transmissão de doenças infecciosas pelo beijo na boca e saliva (71%), que possivelmente se confirmou pela baixa ocorrência de lesões após o ato do beijo e pela observação da boca do parceiro antes de beijar. Conclusão: A pratica do beijo na boca e o sexo oral devem ser temáticas consideradas na assistência fornecida a adolescentes. O uso de estratégias preventivas e o acesso às redes sociais podem contribuir para a redução de situações de risco advindos de situações de vulnerabilidade.

Aim: To describe the knowledge about the kiss on the mouth and its possibility of transmission of infectious diseases in a group of adolescents from private schools in Nova Iguaçu / Rio de Janeiro, through this pilot study. Methodology: Cross-sectional study in which a self-administered semi-structured question script was applied to adolescents (18 and 19 years) of both genders, belonging to three schools of the private school system of Nova Iguaçu, Rio de Janeiro State. Results: Of a total of 100 adolescents who participated in this study, more than half were single and female (61%), only students as occupation (88% of the total) and 96% had already kissed the mouth. The selected sample demonstrated its own characteristics, with the high frequency of the knowledge of the possibility of transmission of infectious diseases by kissing in the mouth and saliva (71%), which was possibly confirmed by the low occurrence of lesions after the kiss and the observation of the mouth. of the partner before kissing. Conclusion: The practice of kissing on the mouth and oral sex should be thematic considered in the care provided to adolescents. The use of preventive strategies and access to social networks can contribute to the reduction of risk situations arising from vulnerability situations. Keywords: mouth, infectious diseases, adolescent (s), health education, strategies and oral health

Recall Rates of Patients in Endodontic Treatments: A Critical Review.

The number of patients that return for recall appointments has great importance to validate endodontic treatment outcomes. The purpose of this review was to investigate the rate of return on recall and the main factors that influence this rate of return. A literature review was performed in the PubMed database for the years from 1978 to 2017, using the following keywords: recall rate, endodontic treatment, endodontic retreatment, apical surgery. The inclusion criteria were: prospective studies in English, and in vivo research with humans, which included patient return rates. A total of 35 studies that fulfilled the established criteria were selected. The percentage of patients who returned on recall was 56%. More female patients (60%) attended the recall appointments than male (40%). The three main reasons for not returning were: patients did not observe the follow-up appointment (490), not returning due to a lack of interest (99) and changing their address (222). The age of the patients attending the appointments varied from 28.6 to 62 years old, with the highest percentage of patients that returned ranging from 40 to 52.5 years old. According to the literature the optimal rate of return for follow-up treatment should be greater than 80%, for the validity of the research. However, the reality presented in the studies is far from ideal. Many studies do not even mention these rates of return in their methodologies or in their results, which may mask the true treatment success rates.
