OBJECTIVE: To establish the implementation of nursing diagnoses and care for the spiritual dimension of people with cancer. METHOD: Action research in a university hospital in the north-east of Brazil. Nine nurses and thirteen nursing technicians from the Onco-hematology and Bone Marrow Transplant Unit of this hospital took part. Data collection took place in four phases and involved the talking map technique, pedagogical workshops and a logbook. The groups' speeches were coded using Maxqda software, subjected to Braun and Clarke's thematic analysis and interpreted in the light of Paulo Freire's constructs. RESULTS: Phase 1 sought to apprehend the participants' prior knowledge on the subject; in phase 2, proposals emerged for spiritual care organized in the Nursing Process; in phase 3, the diagnoses and care plan for the spiritual dimension for clinical practice were contemplated; and in phase 4, through the final evaluation, it was possible to see the transformations that occurred in the nursing team's practice with the proposed implementation. CONCLUSION: The educational actions provided significant learning for the nursing team and the implementation of diagnoses and nursing care for the spiritual dimension of people with cancer.

Gene variations related to the hepatocellular carcinoma: Results from a field synopsis and Bayesian revaluation.

Hepatocellular carcinoma (HCC) is considered as the second cause of cancer-related deaths worldwide. Genetic variations are associated with HCC risk, an issue that has been the subject of several meta-analyses. However, meta-analyses have an important limitation on the likelihood of false positive data. Henceforth, this study aimed to assess the level of noteworthiness in the meta-analyses by means of a Bayesian approach. A systematic search was performed for meta-analyses with associations between gene polymorphisms and HCC. The calculations for the False-Positive Rate Probability (FPRP) and the Bayesian False Discovery Probability (BFDP) were performed to assess the noteworthiness with a statistical power of 1.2 and 1.5 of Odds Ratio at a prior probability of 10-3 and 10-5. The quality of studies was evaluated by the Venice criteria. As additional analyses, the gene-gene and protein-protein networks were designed for these genes and products. As results, we found 33 meta-analytic studies on 45 polymorphisms occurring in 35 genes. A total of 1,280 values for FPRP and BFDP were obtained. Seventy-five for FPRP (5.86%) and 95 for BFDP (14.79%) were noteworthy. In conclusion, the polymorphisms in CCND1, CTLA4, EGF, IL6, IL12A, KIF1B, MDM2, MICA, miR-499, MTHFR, PNPLA3, STAT4, TM6SF2, and XPD genes were considered as noteworthy biomarkers for HCC risk.

Food restriction reduces hepatic alterations associated with experimental periodontitis.

BACKGROUND: Periodontitis is a chronic inflammatory and multifactorial disease that affects the periodontal structures and can cause alterations in the hepatic tissue. The aim of the present study was to evaluate whether a diet with food restriction can decrease oral and liver alterations associated with ligature-induced periodontitis. METHODS: Twenty-four female Wistar rats were used in this study, randomized into three groups (n = 8 for each group): control (regular food); periodontitis (regular food + periodontitis induced with ligatures); and food restriction (diet with food restriction and periodontitis induction). The following periodontium parameters were analyzed tooth mobility (TM), probing pocket depth (PPD), gingival bleeding index (GBI), and alveolar bone height (ABH). In the liver, the levels of oxidative stress markers-malondialdehyde (MDA), glutathione (GSH), total cholesterol, and levels of myeloperoxidase (MPO) activity were measured. Liver samples were analyzed for histopathological score. In the blood tissue, the levels of enzymes alanine aminotransferase (ALT), aspartate aminotransferase (AST), glucose, total cholesterol, and the high-density lipoprotein (HDL) were also evaluated. RESULTS: The animals that received a diet with food restriction + periodontitis showed a decrease in hepatic histopathological score (P < 0.05) when compared with the periodontitis group, the same for glucose, total cholesterol, ALT, AST, and ABH data. The group with food restriction + periodontitis showed a decrease in the histopathological liver score (P < 0.05) compared with the group with periodontitis. CONCLUSION: This study revealed that food restriction reduced oral damages, as well as hepatic, blood and alveolar bone alterations associated with ligature-induced periodontitis in rats.

Abstract Objective to identify the behavioral responses presented by elderly people at home after hospitalization at the intensive care unit and hospital discharge. Method a qualitative study was conducted with people aged 80 years or older. The data collection setting was the intensive care unit and the homes of the elderly people hospitalized in the unit using open interviews. Data analysis consisted of Bardin's method of content analysis based on the Callista Roy adaptation model. All ethical aspects were respected. Results two categories emerged: changes in the pattern of response to physiological needs and loss of autonomy and psychosocial changes and impairment in performing daily leisure and work activities. Conclusion and implications for practice behavioral responses were related to physiological and psychosocial factors, culminating in dependence and loss of autonomy to perform basic life activities. Difficulties experienced in returning home were also noticed, which caused significant changes in daily activities, thereby evidencing the need for multidisciplinary teams to begin preparing for the return home during hospitalization. Strategies seeking to improve critical care outcomes are highly suggested to be implemented in this population.

Deposition of Immune Complexes in Gingival Tissues in the Presence of Periodontitis and Systemic Lupus Erythematosus.

Systemic lupus erythematosus (SLE) is a complex chronic autoimmune disease characterized by tissue damage and widespread inflammation in response to environmental challenges. Deposition of immune complexes in kidneys glomeruli are associated with lupus nephritis, determining SLE diagnosis. Periodontitis is a chronic inflammatory disease characterized by clinical attachment and bone loss, caused by a microbial challenge - host response interaction. Deposition of immune complex at gingival tissues is a common finding in the course of the disease. Considering that, the primary aim of this study is to investigate the deposition of immune complexes at gingival tissues of SLE patients compared to systemically healthy ones, correlating it to periodontal and systemic parameters. Twenty-five women diagnosed with SLE (SLE+) and 25 age-matched systemically healthy (SLE-) women were included in the study. Detailed information on overall patient's health were obtained from file records. Participants were screened for probing depth (PD), clinical attachment loss (CAL), gingival recession (REC), full-mouth bleeding score (FMBS) and plaque scores (FMPS). Bone loss was determined at panoramic X-ray images as the distance from cementenamel junction to alveolar crest (CEJ-AC). Gingival biopsies were obtained from the first 15 patients submitted to surgical periodontal therapy of each group, and were analyzed by optical microscopy and direct immunofluorescence to investigate the deposition of antigen-antibody complexes. Eleven (44%) patients were diagnosed with active SLE (SLE-A) and 14 (56%) with inactive SLE (LES-I). Mean PD, CAL and FMBS were significantly lower in SLE+ than SLE-(p < 0.05; Mann Whitney). The chronic use of low doses of immunosuppressants was associated with lower prevalence of CAL >3 mm. Immunofluorescence staining of markers of lupus nephritis and/or proteinuria was significantly increased in SLE+ compared to SLE-, even in the presence of periodontitis. These findings suggest that immunomodulatory drugs in SLE improves periodontal parameters. The greater deposition of antigen-antibody complexes in the gingival tissues of patients diagnosed with SLE may be a marker of disease activity, possibly complementing their diagnosis.

Polymorphisms in the interleukin genes and chronic periodontitis: A field synopsis and revaluation by Bayesian approaches.

Periodontitis is a high prevalent disease into the clinical dentistry. Genetic variations in interleukins (IL) genes were associated with chronic periodontitis (CP) and were focus of several meta-analyses. This study aimed to assess the noteworthiness in the meta-analyses by means of a Bayesian approach to determinate possible false report associations. A systematic search was performed for meta-analyses with associations between gene polymorphisms in interleukins and CP. The calculations for the False-Positive Rate Probability (FPRP) and the Bayesian False Discovery Probability (BFDP) were performed to assess the noteworthiness with a statistical power of 1.2 and 1.5 of Odds Ratio at a prior probability of 10-3 and 10-6. As results, eight meta-analyses approaching the IL1A/rs1800587, IL1B/rs1143634, IL1RN/rs2234663, IL4/rs2243250, IL6/rs1800795/rs1800796, IL17A/rs2275913 and IL18/rs1946518/rs187238 polymorphisms have been identified. Twenty-two from 270 calculations (8.15%) were noteworthy. Herein, we have identified the IL1A and IL1B polymorphisms as noteworthy biomarkers for CP susceptibility.

Considering that, the primary aim of this study is to investigate the deposition of immune complexes at gingival tissues of SLE patients compared to systemically healthy ones, correlating it to periodontal and systemic parameters. Twenty-five women diagnosed with SLE (SLE+) and 25 age-matched systemically healthy (SLE­) women were included in the study. Detailed information on overall patient's health were obtained from file records. Participants were screened for probing depth (PD), clinical attachment loss (CAL), gingival recession (REC), full-mouth bleeding score (FMBS) and plaque scores (FMPS). Bone loss was determined at panoramic X-ray images as the distance from cementenamel junction to alveolar crest (CEJ-AC).

Alpha-terpineol complexed with beta-cyclodextrin reduces damages caused by periodontitis in rats.

BACKGROUND AND OBJECTIVE: This study aimed to assess the effectiveness of the treatment with alpha-terpineol (αTPN) complexed with beta-cyclodextrin (ßCD) on oral, blood, and hepatic parameters in ligature-induced periodontitis. MATERIAL AND METHODS: Forty female rats were distributed among the following groups: control (vehicle solution), periodontitis (ligature + vehicle solution), 5 mg/kg of αTPN-ßCD (ligature), and 25 mg/kg of αTPN-ßCD (ligature). Compounds were administered daily via intraperitoneal injection over a 20-day period. Periodontitis was induced with the bilateral insertion of ligatures around the first lower molars of each rat. Oral parameters, as well as blood biomarkers, were measured: histopathological assessment of the hepatic tissue was carried out using light and transmission electron microscopy. RESULTS: The treatment with αTPN-ßCD significantly improved several oral parameters and blood biomarkers in comparison with rats with periodontitis. In addition, the treatment with αTPN-ßCD significantly ameliorated the steatosis score and reduced the number of lipid droplets and the amount of foamy cytoplasm in the hepatocytes of rats with periodontitis. CONCLUSION: The results obtained suggest that the treatment with αTPN-ßCD improves several oral and blood parameters in rats with experimental periodontitis. In addition, hepatic alterations caused by periodontitis were ameliorated in the rats treated with αTPN-ßCD.

Host-Microbial Interactions in Systemic Lupus Erythematosus and Periodontitis.

Background: Systemic lupus erythematosus (SLE) is a potentially fatal complex autoimmune disease, that is characterized by widespread inflammation manifesting tissue damage and comorbidities across the human body including heart, blood vessels, joints, skin, liver, kidneys, and periodontal tissues. The etiology of SLE is partially attributed to a deregulated inflammatory response to microbial dysbiosis and environmental changes. In the mouth, periodontal environment provides an optimal niche for local and systemic inflammation. Our aim was to evaluate the reciprocal impact of periodontal subgingival microbiome on SLE systemic inflammation. Methods: Ninety-one female subjects were recruited, including healthy (n = 31), SLE-inactive (n = 29), and SLE-active (n = 31). Patients were screened for probing depth, bleeding on probing, clinical attachment level, and classified according to CDC/AAP criteria with or without periodontal dysbiosis. Serum inflammatory cytokines were measured by human cytokine panel and a targeted pathogenic subgingival biofilm panel was examined by DNA-DNA checkerboard from subgingival plaque samples. Results: The results showed significant upregulation of serum proinflammatory cytokines in individuals with SLE when compared to controls. Stratification of subject's into SLE-inactive (I) and SLE-active (A) phenotypes or periodontitis and non-periodontitis groups provided new insights into SLE pathophysiology. Ten proinflammatory cytokines were upregulated in serum of SLE-I only and one in SLE-A only. Four molecules overlapped in SLE-A and SLE-I. Anti-inflammatory cytokines included IL-4 IL-10, which were upregulated in SLE-I sera (but not SLE-A), controlling clinical phenotypes. Out of 24 significant differential oral microbial abundances found in SLE, 14 unique subgingival bacteria profiles were found to be elevated in SLE. The most severe oral pathogens (Treponema denticola and Tannerella forsythia) showed increase abundances on SLE-A periodontal sites when compared to SLE-I and healthy controls. Inflammation as measured by cytokine-microbial correlations showed that periodontal pathogens dominating the environment increased proinflammatory cytokines systemically. Conclusions: Altogether, low-grade systemic inflammation that influenced SLE disease activity and severity was correlated to dysbiotic changes of the oral microbiota present in periodontal diseases.

High-fat diet aggravates the liver disease caused by periodontitis in rats.

BACKGROUND: Periodontitis is an inflammatory disease that causes periodontium and hepatic alterations. Liver disease is related to the intake of foods rich in fat and sugars (high-fat). The objective of this study was to evaluate whether a high-fat diet can aggravate the liver disease caused by ligature-induced periodontitis in rats. METHODS: Twenty-one female rats were divided into three groups (n = 7 in each group): control; periodontitis (periodontitis induced with ligature) and high-fat + periodontitis (received hypercaloric diet and induction of periodontitis). The rats were submitted to the analyses of the following periodontal parameters: gingival bleeding index (GBI), probing pocket depth (PPD), tooth mobility (TM), and alveolar bone height. In the hepatic tissue, the levels of malondialdehyde (MDA), glutathione (GSH), total cholesterol, and myeloperoxidase activity (MPO) were measured. Liver samples were also histopathologically evaluated. Finally, blood levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), glucose, total cholesterol, cholesterol high-density lipoprotein (HDL), and uric acid were measured. RESULTS: The high-fat + periodontitis group presented an increase in the steatosis score (P < 0.05) for the histopathologic evaluation, when compared with the periodontitis group. MDA, uric acid and ALT levels also increased, whereas GSH and HDL levels showed lower values. CONCLUSION: A high-fat diet aggravates the liver disease caused by ligature-induced periodontitis in rats.

Periodontitis causes abnormalities in the liver of rats.

BACKGROUND: Periodontitis not only causes injury to the periodontium, but also damages other tissues such as: articulate, renal, cardiac, and hepatic. The objective of this study was to investigate periodontitis induced alterations in liver function and structure using an experimental model. METHODS: Twenty female rats (Rattus norvegicus) were allocated into two groups: control and periodontitis. Gingival bleeding index and oxidative stress parameters and specific circulating biomarkers were measured. Immunohistochemistry was carried out using alkaline phosphatase (AlkP) staining of the liver. Hepatic tissues, cytokines, and lipid contents were measured. Histopathologic evaluation of the liver was carried out using light and electron microscopy. RESULTS: Liver histopathologic and immunohistochemistry assessment showed increase in steatosis score, and presence of binucleate hepatocytes and positive cells for AlkP in periodontitis versus control group. Ultrastructural evaluation showed significant increase in size and number of lipid droplets (LD), distance between the cisterns of rough endoplasmic reticulum (RER), mitochondria size, foamy cytoplasm, and glycogen accumulation in the liver of the periodontitis group compared with the control group. In addition, plasma levels of AlkP, high-density lipoprotein (HDL), triglycerides, and total cholesterol were also changed. CONCLUSION: Experimental periodontitis caused immunohistochemistry, histopathologic, ultrastructural, oxidative, and biochemical changes in the liver of rats.

Polymorphisms in interleukins 17A and 17F genes and periodontitis: results from a meta-analysis.

Polymorphisms in inflammatory genes such as interleukins 17A and 17F are associated with the risk of development of periodontitis, although the results remain contradictory. Hence, the aim of this study was perform a meta-analysis focusing on two polymorphisms (rs2275913 and rs763780) in interleukins 17A and 17F genes, respectively, in both chronic (CP) and aggressive periodontitis (AgP). A review in literature was performed in several databases for studies published before 25, September 2016. The meta-analysis was obtained through the review manager statistical software (version 5.2) with odds ratio (OR) calculation and funnel plot (P < 0.05) for heterogeneity, as well as the comprehensive meta-analysis software (version 3.3.070) for the assessment of publication bias. Seven articles with 1540 participants composed the results in which the mutant allele in the rs2275913 polymorphism did not present significant association with the risk of CP or AgP (OR 1.56, 95% CI 0.77, 3.15, P = 0.21; OR 1.12, 95% CI 0.05, 23.44, P = 0.94, respectively) nor was the mutant allele in rs763780 associated with the risk of CP (OR 1.19, 95% CI 0.80, 1.76, P = 0.39) or AgP (OR 1.07, 95% CI 0.63, 1.84, P = 0.79). No bias of publication was observed by Egger's and Begg's tests in any allelic evaluation. This meta-analysis showed a non-significant association between the polymorphisms rs2275913 and rs763780 in interleukins 17A and 17F genes and chronic and aggressive periodontitis in the allelic evaluation.

Genetic Factors and the Risk of Periodontitis Development: Findings from a Systematic Review Composed of 13 Studies of Meta-Analysis with 71,531 Participants.

Purpose. This work aimed to synthesize the results of recent meta-analysis focusing on polymorphism in inflammatory mediators and its relation with the risk of periodontitis development. Materials and Methods. A systematic search was conducted using databases for publications prior to October 2016. Three examiners extracted data from articles with a clear association between polymorphisms in the inflammatory mediator gene and the development of periodontitis through meta-analysis using the fixed or randomized statistical models to calculate the Odds Ratio with values of P < 0.05 considered significant. Results. A total of 13 meta-analysis articles with 25 polymorphisms in seven interleukins (IL-1A, IL-1B, IL-4, IL-6, IL-8, IL-10, and IL-18), three cellular receptors (Fcγ receptors: FCGR2A, FCGR3A, and FCGR3B), and five inflammatory mediators (COX-2, MMP-2, MMP-3, MMP-8, and MMP-9), with a total of 71,531 participants, approaching different classifications of the disease. Conclusion. The study demonstrated that polymorphisms in the IL-1A, IL-1B, IL-6, IL-10, MMP-3 (chronic form), and MMP-9 (chronic form) polymorphisms were significantly associated with the risk of developing periodontitis, whereas other polymorphisms in the IL-4, IL-8, IL-18, Fcγ, COX-2, MMP-2, MMP-3 (aggressive), MMP-8, and MMP-9 (aggressive) polymorphisms had no significant association with risk of developing periodontitis.

Avaliação clínica e microbiológica relacionada à doença periodontal em pacientes com lúpus eritematoso sistêmico / Clinical and microbiological analysis of parameters related to periodontal disease in systemic lupus erythematous patients

O lúpus eritematoso sistêmico (LES) é uma doença autoimune caracterizada por hiperatividade imunológica crônica pela ação de autoanticorpos que afetam diversos órgãos. Embora o uso crônico de imunossupressores predisponha o paciente a infecções, poucas pesquisas avaliaram uma possível associação entre doença periodontal e LES. Os objetivos deste trabalho foram investigar, por meio de estudo caso-controle, a prevalência e a gravidade da doença periodontal em pacientes com LES, e identificar e quantificar as principais bactérias periodontais presentes no biofilme subgengival. Foram incluídas 60 mulheres em atendimento no Setor de Reumatologia do Hospital Universitário de Brasília, de 20 a 65 anos de idade, sendo subdivididas em LES-A (ativo; n= 31) e LES-I (inativo; n=29). O grupo controle foi composto por 31 mulheres com os mesmos critérios de inclusão, porém sem doenças sistêmicas. As pacientes foram avaliadas quanto às medidas de profundidade de sondagem (P.S), perda de inserção clínica (PIC), índice de sangramento do sulco (ISS) e índice de placa (IPl) no exame inicial. Foram coletados biofilmes subgengivais dos quatro sítios mais profundos para identificação e quantificação de periodontopatógenos por meio de hibridação DNA-DNA checkerboard. Não houve diferenças estatisticamente entre os grupos relativamente aos parâmetros clínicos periodontais, exceto para o ISS, que foi menor no LESA (11,19% ± 14,62%) comparativamente ao grupo controle (17,30% ± 14,88%), porém sem diferenças quando comparado com o grupo LES-I (11,34% ± 11,59%). Houve baixa prevalência de bolsas periodontais, de PIC ≥ 4 mm e de espécies de Actinomyces em todos os grupos. Verificou-se aumento na contagem de bactérias do complexo vermelho no grupo LES-I (4,07 x 105; 95% CI: 0,16-0,79) em relação ao grupo controle (2,50 x 105; 95% CI: 1,23-3,77), com diferenças estatisticamente significante apenas referente ao grupo LES-A (p< 0,05; Kruskal Wallis pós-teste Dunn; 0,45 x 105; 95% CI: 0,16-0,79). Os resultados desse estudo demonstraram que os parâmetros periodontais são semelhantes entre pacientes com LES e grupo controle. O grupo de LES-I apresentou maior tempo dessa doença; aumento da contagem de microorganismos (especialmente dos complexos vermelho e verde em amostras de biofilme subgengival) e pior condição periodontal.(AU)

Systemic lupus erythematous (SLE) is an autoimmune disorder characterized by chronic immunological hyperactivity resultant from the action of autoantibodies, affecting many organs. Although the use of immune suppressors may predispose infections, few studies have investigated the prevalence and severity of periodontal disease in SLE patients. The aim of this study is to investigate the prevalence and severity of periodontal disease in SLE patients and the sub gingival levels of different pathogens. A total of 60 women attending of Brasília University Hospital, aged 18-65 years, were invited to participate in the study. SLE patients were allocated in two subgroups according with disease activity: SLE-A (active disease; n= 31) and SLE-I (inactive disease; n= 29). A number of 31 systemically healthy women at the same age range composed control group. Patients were clinically examined according to probing depth (PD), clinical attachment level (CAL), sulcular bleeding index (SBI) and plaque index (PLI) at baseline examination. Sub gingival biofilm samples were collected from the deepest four sites before periodontal treatment in order to identify and quantify the level of periodontopathogens by checkerboard DNA-DNA hybridization. No significant differences were found between groups in PD, CAL and PLI. Significant differences were observed in GBI between SLE-A (11,19% ± 14,62%) compared to controls (17,30% ± 14.88%), although with no differences when compared to SLE-I (11,34% ± 11,59%). There was a low prevalence of PD and attachment loss ≥ 4 mm at all groups. A low prevalence of Actinomyces was observed at all groups, with an increase in red complex species at LES-I (4,07 x 105; 95% CI: 0,16-0,79) compared to control (2,50 x 105; 95% CI: 1,23-3,77), although with significant differences (p< 0,05; Kruskal Wallis post hoc Dunn) only when compared to SLE-A (0,45 x 105; 95% CI: 0,16-0,79). These findings show no differences in the periodontal conditions of SLE compared to systemically healthy patients, except for a decrease in gingival bleeding index, especially at SLE-A. Reductions in microorganisms' count were observed at SLE-A, while an increase in bacterial count, especially at red and green complex, were observed at subgingival biofilm of SLE-I patients.(AU)

Removal of black stains from teeth by photodynamic therapy: clinical and microbiological analysis.

Black-pigmented bacteria (BPB) are Gram-negative anaerobic, non-motile, proteolytic rods strongly implicated in the pathogenesis of periodontal disease. Although pigments are produced in vitro, black pigmentation is rarely found clinically. However, it may compromise aesthetics and contribute to gingival inflammation. The aim of this report is to describe a clinical case of a 10-year-old boy showing black pigmentation covering all teeth and to propose an alternative therapy for removal of black pigmentation, based on photodynamic therapy (PDT). In order to perform microbiological analysis, plaque samples were collected before and after PDT, and analysed by real-time-PCR (RT-PCR). The results showed a significant reduction in BPB levels after therapy, along with clinical evidence of absence of black pigmentation and reduction in gingival bleeding, although the plaque index remained unaltered. This case showed that PDT is effective for eliminating black pigmentation caused by BPB, without recurrence during a follow-up period of 7 months.

Shells and Bones: A Forensic Medicine Study of the Association of Terrestrial Snail Allopeas micra with Buried Human Remains in Brazil.

Little is known regarding the scavenger fauna associated with buried human corpses, particularly in clandestine burials. We report the presence of 20 shells of the terrestrial snail Allopeas micra, within hollow bones of human remains buried for 5 years, during the process of collecting DNA material. The fact that a large number of shells of A. micra had been found in the corpse and in the crime scene supports the assumption that there was no attempt to remove the corpse from the area where the crime occurred. Despite this, our observations cannot be used to estimate the postmortem interval because there is no precise knowledge about the development of this species. This is the first record of a terrestrial snail associated with a human corpse and its role in this forensic medicine case.

Oral manifestations associated with systemic complications of prune belly syndrome.

Prune belly syndrome (PBS) is a rare congenital malformation of unknown etiology characterized by congenital abnormalities including abdominal wall flaccidity, urinary tract alterations, and bilateral cryptorchidism. The incidence of the syndrome is between 1/35000 and 1/50000 live births and there is little information about the oral findings. The present case describes the oral manifestations of a 15-year-old boy diagnosed with PBS. The findings include enamel hypoplasia associated with generalized hypocalcemic dental lines. In the radiographic exam, pronounced demineralization of the trabecular bone of the jaws, loss of lamina dura in all the teeth, and discontinuity of the mandibular cortical bone were observed. Prune belly syndrome is a rare disease, whose clinical dental aspects are not pathognomonic of the syndrome. The comprehension of the systemic mechanism of PBS and its comorbidities enable an understanding of the systemic etiologic factors associated with oral manifestations.

Biomodificação química das superfícies radiculares dentárias e seus aspectos biológicos / Chemical root surfaces biomodification and biological aspects

A doença periodontal produz mudanças substanciais na superfície radicular. A inflamação mediada pela placa dentobacteriana destrói as fibras de Sharpey e permite a migração apical do epitélio juncional ou do epitélio da bolsa periodontal. Assim, a superfície radicular se torna exposta ao ambiente bucal, tendo perda de colágeno, superfície hipermineralizada, além de túbulos dentinários e cemento contaminados. Desta forma, a superfície da raiz se torna inadequada à inserção de fibras de tecido conjuntivo, necessárias à regeneração periodontal. O objetivo deste trabalho foi realizar uma revisão de literatura acerca da biomodificação radicular, abordando as atuais controvérsias quanto ao benefício do uso do ácido na regeneração periodontal, protocolos de aplicação na superfície radicular contaminada, assim como do efeito biológico proporcionado por esses agentes.
