A Novel Analysis via Micro-CT Imaging Indicates That Chemically Modified Tetracycline-3 (CMT-3) Inhibits Tooth Relapse after Orthodontic Movement: A Pilot Experimental Study.

OBJECTIVE: To evaluate the effect of chemically modified tetracycline-3 (CMT-3) and simvastatin on tooth relapse after orthodontic movement in rats using a novel analysis method employing high-resolution micro-CT (Micro-CT) images. In addition, the correlation between bone density and orthodontic relapse was also evaluated for each experimental group. METHODS: Forty adult male Wistar rats had stainless steel springs installed on their left upper first molars in order to generate tooth movement for 18 days. After this initial period, the animals were divided into three groups: (1) 30 mg/kg of CMT-3; (2) 5 mg/kg of simvastatin; and (3) 0.5% carboxymethylcellulose, and each group was treated for 20 days. Micro-CT images were analyzed (conventional method and 3D reconstruction) on the 7th and 18th days following spring fixation and finally, 20 days after treatment either with CMT-3 or simvastatin (38th day). Bone mineral density (BMD) of the mesial and distal roots of the upper first molar was also analyzed. RESULTS: The difference was statistically significant between the groups as to recurrence (p=0.048), and the post hoc test identified the value of p=0.007 between the control group and the CMT-3 group. Simvastatin was not able to inhibit tooth relapse. The bone mineral densities of both the mesial and distal roots were different between the three groups, after the 20th day of drug use (p=0001 and p < 0001). CONCLUSION: Our findings support the initial evidence that CMT-3 is able to prevent relapse after tooth movement. Future trials in humans should evaluate such treatment as a promising approach to preventing this common phenomenon. CLINICAL RELEVANCE: Considering the results obtained, CMT-3 can be used to avoid relapse after tooth movement.

Oral lichen planus and malignant transformation: The role of p16, Ki-67, Bub-3 and SOX4 in assessing precancerous potential.

The association of oral lichen planus (OLP) lesions with malignant transformation risk has remained a controversial topic and is of clinical importance. Therefore, the present study evaluated the expression levels of p16, Ki-67, budding uninhibited by benzimidazoles 3 (Bub-3) and sex-determining region Y-related high mobility group box 4 (SOX4), and their roles as precancerous biomarkers in OLP. A retrospective study was performed, in which tissue blocks of OLP, oral dysplasia (OD), cutaneous lichen planus (CLP) and oral fibrous hyperplasia (OFH) were used (n=120). A positivity index (PI) for p16, BUB3, Ki-67 and SOX4 expression was calculated in each group. The PI for p16 was 20.65% for OLP, 7.85% for OD, 86.59% for CLP and 11.8% for OFH, and the difference between these groups was statistically significant (P<0.001). PIs of Ki-67 were indicated as 11.6% for OLP, 14.4% for OD, 8.24% for CLP and 5.5% for OFH, and a statistically significant difference was observed between the groups (P<0.001). Notably, the expression levels of BUB3 were not statistically different among groups. The highest expression levels of SOX4 were identified in CLP (P<0.001 vs. OLP/CLP; P=0,001 vs. CLP/OD). The determined expression levels of p16 and Ki-67 suggest that specific OLP lesions may have an intermediate malignant potential and should be carefully followed up. The intense SOX4 staining in CLP indicated a different proliferation pattern of epithelium compared with oral mucosa cells. These findings suggest that SOX4 expression may also be associated with the different clinical courses of OLP and CLP.

Assessment of the accuracy of portable monitors for halitosis evaluation in subjects without malodor complaint. Are they reliable for clinical practice?

Halitosis is defined as a foul odor emanated from the oral cavity, with great impact in quality of life and social restraints. Recently, the use of Breath Alert™ in research increased significantly. Halimeter™, another portable device, is often used in clinical practice. Nevertheless, not many studies have verified the accuracy and compared the results of both devices simultaneously. OBJECTIVE: To verify the accuracy of Breath Alert™ and Halimeter™ in patients without chief complaint of halitosis, using the organoleptic test (OT) as "gold standard." The second aim was to verify whether their concomitant use could enhance the diagnostic accuracy of halitosis. MATERIAL AND METHODS: A cross-sectional analytical study was performed. The quality of expired air of 34 subjects without chief complaint of halitosis was assessed. Two experienced examiners carried out the OT. Afterward, a third blinded examiner performed Halimeter™ (HT) and Breath Alert™ (BA) tests. RESULTS: The OT identified halitosis in 21 subjects (62%). The area under the ROC curve (95% confidence interval) was 0.67 (0.48-0.85) and 0.54 (0.34-0.75) for HT and BA, respectively. The accuracy for HT and BA was 59% and 47%, respectively. The combined usage of HT and BA provided 11 positive results, being 9 subjects (43%) out of the total of 21 positive cases. CONCLUSIONS: Halimeter™ and Breath Alert™ were not able to diagnose halitosis in non-complainer subjects at the same level as the organoleptic examination, since their accuracy were low. Our results suggest that such portable devices are not reliable tools to assess halitosis and may neglect or misdiagnose a considerable number of patients in clinical practice.

Salivary proteomics: A new adjuvant approach to the early diagnosis of familial juvenile systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) is a chronic multisystemic disease characterized by autoimmune inflammatory disturbance. Pleomorphic manifestations are present and a potentially progressive and debilitating course can be detected. SLE rarely manifests before age 5, and its onset peaks is around puberty. Although clinical manifestations, immunological alterations and treatment do not differ between juvenile and adult SLE, children tend to present with a more aggressive disease course than adults. Hence, autoimmune rheumatic diseases are the most common cause of morbidity and mortality in pediatric populations. Blood serum analysis plays an especially important role in the detection and monitoring of autoantibodies in SLE. However, since blood sampling is an uncomfortable procedure, especially in children, novel less invasive techniques and approaches are of utmost importance to evaluate pediatric subjects. In this regard, saliva samples have several advantages, such as: easy access, fast collection, painless and riskless procedure. Saliva has antimicrobial, immunomodulatory and anti-inflammatory properties, as well as several other relevant features. The whole saliva is a complex mixture of major and minor salivary gland secretion, gingival crevicular fluid, transudates plasma protein, keratinocyte products and oral microbiota. This biological fluid reflects the physiological state of the body, including the emotional condition, and endocrine, nutritional and metabolic changes. Therefore, salivary proteomics is becoming increasingly used for the early diagnosis of several diseases such as breast cancer, oral cancer, Sjögren's syndrome, diffuse systemic sclerosis, rheumatoid arthritis, among others. Considering the detection of some potential markers related to SLE in serum and urine, this study aims to conduct an initial evaluation of the possible presence of such biomarkers in saliva. Furthermore, it is expected to track down new salivary proteins that could be correlated with the disease. As such, it is important to evaluate whether the analysis of the salivary proteome of children whose mothers have SLE may help identify biomarkers for the early detection and monitoring of the condition.

Salivary function impairment in type 2 Diabetes patients associated with concentration and genetic polymorphisms of chromogranin A.

OBJECTIVES: The purpose of this study was to evaluate the effect of type 2 diabetes mellitus (T2DM) on salivary function impairments according to glycemic control status and subsequently compare the concentration of chromogranin A (CHGA) with its genetic profile. MATERIALS AND METHODS: Thirty-six patients with controlled T2DM, 36 with poorly controlled T2DM, and 38 nondiabetic subjects underwent salivary flow rate measurements by means of unstimulated labial (ULS), unstimulated whole (UWS), and stimulated whole saliva (SWS) collections. CHGA concentrations were determined in saliva and plasma with ELISA, and two CHGA polymorphisms (T-415C and Glu264Asp) were analyzed by polymerase chain reaction-restriction fragment length polymorphism. RESULTS: T2DM patients presented significantly lower ULS and UWS flow rates regardless of glycemic control status compared to controls (P = 0.002 and P = 0.027, respectively). The SWS flow rate in the poorly controlled T2DM was the lowest among the groups (P = 0.026). Significantly higher plasma and salivary CHGA levels were found in T2DM groups (P = 0.019 and P < 0.001, respectively). CHGA gene variants (T-415C and Glu264Asp) revealed significant differences between diabetics and control subjects when associated with lower salivary flow and higher salivary CHGA production (P < 0.05). CONCLUSIONS: T2DM causes abnormalities in the function of salivary glands. However, poorly controlled T2DM has the most influence on SWS flow rates. Our findings indicate an association between plasma and salivary CHGA levels and T2DM patients. Furthermore, the results suggest that CGHA polymorphisms might be associated with salivary gland hypofunction and higher salivary CHGA production in T2DM patients. Nevertheless, further epidemiological studies are required to elucidate this clinical implication. CLINICAL RELEVANCE: Salivary impairments and high levels of CHGA are associated with T2DM patients. In addition, CGHA polymorphisms might be associated with salivary gland hypofunction and higher salivary CHGA production in T2DM patients. This could be a significant insight to establish a role for salivary CHGA as a potential clinical biomarker to T2DM.

Impact of glycemic control on oral health status in type 2 diabetes individuals and its association with salivary and plasma levels of chromogranin A.

OBJECTIVE: To evaluate the effect of glycemic control status in type 2 diabetes mellitus (T2DM) individuals on clinical oral health indicators and to compare the concentrations of plasma and salivary chromogranin A (CHGA) among nondiabetic subjects and T2DM patients, exploring their associations. DESIGN: In this cross-sectional study, 32 patients with controlled T2DM, 31 with poorly controlled T2DM and 37 nondiabetic subjects underwent a clinical and periodontal examination. CHGA concentrations were determined in saliva and plasma with ELISA. RESULTS: Poorly controlled T2DM group exhibited significantly higher mean buffering capacity, plaque index and bleeding on probing than other groups (P<0.05). No difference was found to DMFT (decayed, missed and filled teeth) index between groups. Sites with clinical attachment loss (CAL) of 4 and 5-6mm were significantly higher in both diabetic groups compared to control group (P<0.05). Poorly controlled T2DM group had significantly higher sites with CAL ≥ 7 mm than other groups (P=0.001). Significantly higher plasma and salivary CHGA levels were found in T2DM groups (P<0.05). In both diabetic groups, probing depths 5-6mm and CAL 5-6mm were associated with higher salivary CHGA concentration (P<0.05). CONCLUSIONS: The findings revealed that T2DM patients were more prone to periodontal tissue damage than to caries risk. The results also provide some evidence that the degree of attachment loss deteriorates significantly with poor glycemic control in T2DM (CAL ≥ 7 mm). Moreover, the results suggest that high concentrations of salivary CHGA are associated with worse periodontal parameters and T2DM, and this could be related to the pathogenesis of both diseases.

Percepções de pacientes sobre a relação entre diabetes mellitus e saúde oral: um estudo transversal / Patients perceptions towards diabetes mellitus and oral health: a cross-sectional study

Purpose: To evaluate the knowledge of diabetic patients towards the connection between diabetes mellitus (DM) and oral diseases. Oral status was also assessed in order to evaluate the correlation among patients' perception and their oral health. Material and Methods: A sample of 132 diabetic subjects answered a questionnaire containing 12 questions addressing their knowledge, attitudes and practices related to oral health. Oral examination accessed the presence of cavity carious lesions, residual roots, dental biofilm, calculus, gingivitis, tooth mobility and gingival recession. Results: Fifty-four percent of the sample had never been instructed by their health professionals that DM could cause oral diseases. However, 66% presumed being more vulnerable to develop oral illnesses and 57.5% answered that they assumed having no oral disturbances at that moment. In contrast, intraoral clinical examination showed that 99% presented at least one oral injury such as caries lesions, plaque/calculus, gingival inflammation, tooth mobility, residual root and xerostomia. Conclusions: Health care professionals usually neglect oral status in diabetic patients. Above all, there is a huge gap between patients' perceptions towards oral health and their real oral status. This study highlights the need of developing new models of prevention that properly address the important clinical relation between oral diseases and DM.(AU)

Sialometry of upper labial minor glands: a clinical approach by the use of weighing method Schirmer's test strips paper.

OBJECTIVES: To establish referential values ranges of hyposalivation and normosalivation for the salivary flow rate (SFR) of upper labial (LS) and palatal (PS) mucosa using Schirmer's test strips paper and as a second goal to determine the values ranges of the SFR of palatal (PS) and upper labial (LS) mucosa in subjects with and without xerostomia. METHODS: A cross-sectional study was conducted among subjects distributed in three groups according to their unstimulated and stimulated whole saliva. RESULTS: 144 subjects were enrolled in groups as follows: severe hyposalivation (n = 24), mild hyposalivation (n = 78), and normosalivation (n = 42). The mean and the 95% confidence interval for the LS flow rate ( µ L/cm(2)/min) were 3.2 (2.46 to 3.94), 5.86 (4.96 to 6.75), and 9.08 (7.63 to 10.53) (P < 0.001) for each group, respectively. The PS results were 1.01 (0.68 to 1.34), 1.72 (1.31 to 2.13), and 2.44 (1.66 to 3.22) (P = 0.014). Xerostomia complainers presented lower rates of LS (5.17 (4.06 to 6.23)) than non-complainers (7.33 (6.4 to 8.27)) (P = 0.003). CONCLUSIONS: The test was reliable to provide referential values ranges for LS flow rate measurement and was shown to be valid to distinguish normosalivation from severe and mild hyposalivation and also to predict xerostomia.

Salivary and serum cortisol levels, salivary alpha-amylase and unstimulated whole saliva flow rate in pregnant and non-pregnant.

PURPOSE: To compare salivary and serum cortisol levels, salivary alpha-amylase (sAA), and unstimulated whole saliva (UWS) flow rate in pregnant and non-pregnant women. METHOD: A longitudinal study was conducted at a health promotion center of a university hospital. Nine pregnant and 12 non-pregnant women participated in the study. Serum and UWS were collected and analyzed every trimester and twice a month during the menstrual cycle. The salivary and serum cortisol levels were determined by chemiluminescence assay and the sAA was processed in an automated biochemistry analyzer. RESULTS: Significant differences between the pregnant and non-pregnant groups were found in median [interquartile range] levels of serum cortisol (23.8 µL/dL [19.4-29.4] versus 12.3 [9.6-16.8], p<0.001) and sAA (56.7 U/L [30.9-82.2] versus 31.8 [18.1-53.2], p<0.001). Differences in salivary and serum cortisol (µL/dL) and sAA levels in the follicular versus luteal phase were observed (p<0.001). Median UWS flow rates were similar in pregnant (0.26 [0.15-0.30] mL/min) and non-pregnant subjects (0.23 [0.20-0.32] mL/min). Significant correlations were found between salivary and serum cortisol (p=0.02) and between salivary cortisol and sAA (p=0.01). CONCLUSIONS: Serum cortisol and sAA levels are increased during pregnancy. During the luteal phase of the ovarian cycle, salivary cortisol levels increase, whereas serum cortisol and sAA levels decline.

MÉTODOS: Trata-se de um estudo longitudinal realizado no centro de promoção da saúde de um hospital universitário. Nove gestantes e 12 não gestantes participaram do estudo. Foram coletados e analisados soro e UWS nos três trimestres gestacionais e duas vezes por mês durante o ciclo menstrual. A análise do cortisol salivar e sérico foi realizada com o uso de quimiluminescência e a atividade da sAA foi determinada por meio de analisador automático para bioquímica. RESULTADOS: Foi verificado que a mediana (intervalo interquartil) dos níveis de cortisol sérico no grupo de gestantes foi maior que 23,8 µL/dL (19,4-29,4) quando comparado ao grupo de não gestantes, que teve média de 12,3 (9,6-16,8; p<0,001). Os níveis de sAA seguiram o mesmo padrão, com médias de 56,7 U/L (30,9-82,2) e 31,8 (18,1-53,2; p<0,001), respectivamente. Foram observadas diferenças dos níveis de cortisol sérico e salivar (µL/dL) e de sAA entre a fase folicular versus a fase lútea (p<0,001). As medianas dos fluxos salivares (UWS) foram semelhantes em gestantes (0,26 [0,15-0,30] mL/min) e não gestantes (0,23 [0,20-0,32] mL/min). Foram encontradas correlações significativas entre o cortisol salivar e o sérico (p=0,02) e entre o cortisol salivar e a sAA (p=0,01). CONCLUSÕES: Os níveis de cortisol sérico de sAA durante a gestação elevam-se. Na fase lútea do ciclo ovariano, os níveis de cortisol salivar aumentam ao passo que os níveis de cortisol sérico e sAA diminuem. .

A importância da brinquedoteca hospitalar e da Terapia Ocupacional sob a óptica da equipe de enfermagem de um hospital público do Distrito Federal / The importance of hospital playroom and Occupational Therapy from the perspective of the nursing team of a public hospital in the Federal District

Introduction: The care provided to hospitalized children under the comprehensive perspective should not be limited simply to drug interventions and rehabilitation techniques. Children must be considered in their own singularities and they should have all known resources available to express themselves, and overcome hospitalization and the illness experience. In this sense, the playing duringthe period of illness and hospitalization represents a preferred means to keep contact with the world around them. Objective: To ascertain the views of the nursing team about the importance of a playroom in the hospital and the role of the occupational therapist in this context. Methods: A questionnaire was applied to the professional nursing staff of the pediatric unit of the third largest hospital in the Federal District. Results: Results demonstrated that the professional nursing team considers the playroom important and recognizes the occupational therapist's value, but they are not aware of the occupational therapist's role and the influence of the playing in the nursing routine. Conclusion: It is extremely necessary that playful activities increasingly gain ground in hospital settings through all subjects involved in the health-disease process in which children are inserted.(AU)

Introdução: O cuidado à criança hospitalizada sob a perspectiva de atenção integral não deve ser limitado às intervenções medicamentosas ou simplesmente às técnicas de reabilitação. A criança necessita ser considerada em sua singularidade e ter à sua disposição recursos que sejam de seu domínio para expressar-se, vivenciar e superar a experiência do adoecimento e da hospitalização. Nesse sentido, o brincar durante o período de adoecimento e internação hospitalar representa um meio privilegiado de ela entrar em contato com o mundo à sua volta. Objetivo: Verificar a opinião da equipe de enfermagem sobre a importância de uma brinquedoteca hospitalar e o modo como percebem o terapeuta ocupacional nesse contexto. Método: Aplicação de um questionário a profissionais da equipe de enfermagem da unidade de pediatria do terceiro maior hospital do Distrito Federal. Resultados: Percebeu-se a importância atribuída à brinquedoteca por parte da equipe de enfermagem, o reconhecimento do valor do terapeuta ocupacional e o desconhecimento acerca do seu papel e da influência do brincar na rotina da enfermagem. Conclusão: É extremamente necessário que o lúdico, cada vez mais, ganhe espaço no âmbito hospitalar, para todos os sujeitos envolvidos no processo saúde doença em que a criança está.(AU)

Sialometria: aspectos de interesse clínico / Sialometry: aspects of clinical interest

A saliva total é um complexo de secreções multiglandulares composto de fluido gengival, células epiteliais descamadas, microrganismos, produtos do metabolismo bacteriano, resíduos alimentares, leucócitos, muco da cavidade nasal e da faringe. A saliva possui diversas funções, incluindo reparação tecidual, tamponamento, proteção, digestão, gustação, ação antimicrobiana, manutenção da integridade do dente e sistema de defesa antioxidante. A redução do fluxo salivar (hipossalivação) é um distúrbio comum, e estima-se que cerca de 20% da população geral tenham esta alteração. A hipossalivação pode ser decorrente de diabetes mellitus, hipotireoidismo, desidratação, comprometimento do parênquima glandular por processos infecciosos, doenças granulomatosas ou condições autoimunes e inflamatórias (como a síndrome de Sjögren e a artrite reumatoide), radioterapia da região cefálica e/ou cervical, bem como pode estar associada a distúrbios do humor, efeitos adversos ocasionados pelo uso de algumas medicações ou, ainda, ser de causa idiopática. As terapias convencionais para o tratamento da redução do fluxo salivar, com o uso de sialogogos gustatórios e químicos, ainda apresentam restrições. Contudo, novas alternativas têm mostrado grande perspectiva no tratamento deste problema. Diagnosticar um paciente como hipossalivador crônico é um desafio na prática clínica, e os métodos de avaliação do fluxo salivar são pouco conhecidos pelos reumatologistas. A avaliação seriada do fluxo salivar é importante para o correto diagnóstico e prognóstico de determinadas condições bucais e sistêmicas. Esta revisão aborda alguns aspectos relacionados à função da saliva, às consequências da hipossalivação e aos métodos de medição da taxa de fluxo salivar, conceitos úteis na prática diária do reumatologista.

Whole saliva is a multiglandular secretion complex consisting of gingival fluid, desquamated epithelial cells, microorganisms, products of bacterial metabolism, food debris, leukocytes mucus from the nasal cavity and the pharynx. Saliva has many functions, including tissue repair, tamponage, protection, digestion, taste, antimicrobial action, maintaining tooth integrity and antioxidant defense system. A decrease in salivary flow (hyposalivation) is a common disorder and it is estimated that approximately 20% of the general population have this alteration. Hyposalivation may be due to diabetes mellitus, hypothyroidism, dehydration, impaired glandular parenchyma by infectious processes, granulomatous diseases or autoimmune and inflammatory conditions (such as Sjogren's syndrome and rheumatoid arthritis), radiotherapy of head and/or neck region, or it may be associated with mood disorders, adverse effects caused by the use of some medications or even be idiopathic. Conventional therapies for the treatment of reduced saliva flow with the use of chemical and gustatory secretagogues are still limited. However, new alternatives have shown great perspective in the treatment of this disorder. To diagnose a patient as having chronic hyposalivation is a challenge in clinical practice and methods of salivary flow assessment are little known by rheumatologists. The serial evaluation of salivary flow is important for the diagnosis and prognosis of certain oral and systemic conditions. This review addresses some aspects related to the role of saliva, the consequences of hyposalivation and methods of salivary flow rate measurement, useful concepts in the daily practice of rheumatology.

Sialometry: aspects of clinical interest.

Whole saliva is a multiglandular secretion complex consisting of gingival fluid, desquamated epithelial cells, microorganisms, products of bacterial metabolism, food debris, leukocytes mucus from the nasal cavity and the pharynx. Saliva has many functions, including tissue repair, tamponage, protection, digestion, taste, antimicrobial action, maintaining tooth integrity and antioxidant defense system. A decrease in salivary flow (hyposalivation) is a common disorder and it is estimated that approximately 20% of the general population have this alteration. Hyposalivation may be due to diabetes mellitus, hypothyroidism, dehydration, impaired glandular parenchyma by infectious processes, granulomatous diseases or autoimmune and inflammatory conditions (such as Sjogren's syndrome and rheumatoid arthritis), radiotherapy of head and/or neck region, or it may be associated with mood disorders, adverse effects caused by the use of some medications or even be idiopathic. Conventional therapies for the treatment of reduced saliva flow with the use of chemical and gustatory secretagogues are still limited.
