Objetivo: Evaluar la frecuencia de manifestaciones orales asociadas a COVID-19 en un segmento de la población paraguaya y determinar cuáles son las más prevalentes. Metodología: Estudio descriptivo de corte transversal. Fue realizada una encuesta electrónica de enero a marzo del 2022. Los datos fueron presentados como frecuencias y porcentajes y analizados mediante la prueba de chi-cuadrado. El análisis estadístico se realizó con el software R versión 4.0.3. Resultados: La muestra estuvo compuesta por 478 personas. El 79,50 % correspondió al sexo femenino y el 45,19 % tenía entre 25 y 34 años. El 65,48 % informó haber experimentado al menos 1 síntoma o signo oral durante el curso de COVID-19. La pérdida de la sensación de sabores amargos, seguida de la alteración del sabor de los alimentos y la pérdida de la percepción dulce, fueron los síntomas más comunes. Se encontró una proporción significativamente mayor de manifestaciones orales en el rango de 18-24 años (χ²; p= 0,003). Entre las personas que desarrollaron COVID-19 de forma moderada a severa hubo mayor número de manifestaciones de síntomas orales (χ²; p= 0,044). Discusión: Se identificó una alta frecuencia de manifestaciones orales en pacientes con casos de moderados a severos de COVID-19, destacándose los trastornos del gusto como los más predominantes. Los individuos más jóvenes fueron los más afectados.


Introduction: Previous studies have reported that patients infected with the COVID-19 virus could manifest symptoms in the oral cavity. Objective: To evaluate the frequency of oral manifestations associated with COVID-19 in a segment of the Paraguayan population and determine the most prevalent ones. Methods: Descriptive cross-sectional study. An electronic survey was conducted from January to March 2022. The data were presented as frequencies and percentages and analyzed using the chi-square test. Statistical analysis was performed with R software version 4.0.3. Results: The sample consisted of 478 individuals. 79.50% were female, and 45.19% were between 25 and 34 years old. 65.48% reported having experienced at least 1 oral symptom or sign during the course of COVID-19. The loss of the sensation of bitter tastes, followed by the alteration of the taste of foods and the loss of sweetness perception, were the most common symptoms. A significantly higher proportion of oral manifestations was found in the 18-24 age range (χ²; p= 0.003). Among people who developed COVID-19 in a moderate to severe form, a greater number of oral symptom manifestations were observed (χ²; p= 0.044). Discussion: A high frequency of oral manifestations was identified in patients with moderate to severe cases of COVID-19, with taste disorders standing out as the most predominant. Younger individuals were the most affected.

ABSTRACT

ABSTRACT Xerostomia emerges as a consequence of salivary gland hypofunction, and seriously compromises the integrity of hard and soft oral tissues, whileperiodontitis is an infectious disease characterized by biofilm accumulation, inflammation and alveolar bone resorption. Aim The aim this study was to compare the deleterious effects caused by experimental hyposalivation, periodontitis, and the combination of both on periodontal tissues and mandibular biomechanics in rats. Materials and Method Hyposalivation (group H) was induced through bilateral submandibulectomy. Periodontitis (group EP) was induced by injecting LPS (1 mg/ml) into the gingiva of the first lower molars. A third group was subjected to both conditions (group H+EP). Alveolar bone loss was evaluated by micro-computed tomography and histomorphometric analysis, and gingival inflammatory mediators were assessed by specific techniques. Biomechanical properties were evaluated in mandible. Results Alveolar bone loss increased similarly in groups H, EP and H+EP compared to control. Metalloproteinase (MMP2 and MMP9) activity was similar in H and control, but higher in groups EP and H+EP (MMP2: C 9644+2214, EP 34441+3336, H 5818+1532, H+EP 42673+3184; MMP9: C 5792+961, EP 14807+861, H 9295+520, H+EP 4838+1531). The rest of the inflammatory mediators evaluated increased in groups H, EP and H+EP to a greater or lesser extent with respect to the control, although in most cases, they were higher in groups EP and H+EP than in group H. The biomechanical properties of the mandible increased in group H compared to the other three groups. Conclusions Both hyposalivation and periodontitis cause periodontal damage, but hyposalivation also produces biomechanical alterations, causing more extensive deleterious effects than periodontitis.


RESUMEN La xerostomía surge como consecuencia de la hipofunción de las glándulas salivales y compromete seriamente la integridad de los tejidos orales duros y blandos, mientras que la periodontitis es una enfermedad infecciosa caracterizada por la acumulación de biofilm, inflamación y reabsorción ósea alveolar. Objetivo El objetivo del presente estudio fue comparar los efectos deletéreos causados por la hiposalivación y la periodontitis experimental, y la combinación de ambas sobre los tejidos periodontales y la biomecánica mandibular en ratas. Materiales y Método La hiposalivación (H) se indujo mediante una submandibulectomía bilateral. Por otra parte, la periodontitis (PE) se indujo mediante la inyección de LPS (1 mg/ml) en la encía de los primeros molares inferiores. Otro grupo se sometió a ambas condiciones (H+PE). La pérdida ósea alveolar se evaluó mediante tomografia microcomputarizada y análisis histomorfométrico, mientras que los mediadores inflamatorios gingivales fueron determinados mediante técnicas específicas. Se evaluaron las propiedades biomecánicas en la mandíbula. Resultados La hiposalivación aumentó la pérdida ósea alveolar en comparación con el control de forma similar a la PE y H+PE. La actividad de las metaloproteinasas (MMP2 y MMP9) fue similar en los grupos H y control, pero resultó mayor en los grupos PE y H+PE (MMP2: C 9644+2214, PE 34441+3336, H 5818+1532, H+PE 42673+3184; MMP9: C 5792+961, PE 14807+861, H 9295+520, H+PE 24838+1531). El resto de los mediadores inflamatorios evaluados aumentaron en mayor o menor medida en los grupos H, PE y H+PE respecto al control, aunque en la mayoría de los casos fueron superiores en los grupos PE y H+PE respecto al grupo H. Sin embargo, las propiedades biomecánicas de la mandíbula aumentaron en el grupo H con respecto a los otros grupos. Conclusiones Tanto la hiposalivación como la periodontitis causan daño periodontal, pero la hiposalivación también produce alteraciones biomecánicas, provocando efectos deletéreos más extensos que la periodontitis.

ABSTRACT

ABSTRACT Objective: To determine the unstimulated salivary flow, pH, and buffering capacity and their associations with systemic conditions and medication use in independently living aged. Material and Methods: This cross-sectional study included 72 participants with a minimum of 60 years recruited in Belo Horizonte, Brazil. A questionnaire was used to collect age, sex, presence of systemic diseases, and medications in continuous use. Salivary data collection was performed to determine unstimulated salivary flow, pH, and buffering capacity. Descriptive, bivariate, and multivariate analyses were performed (p<0.05). Results: Most of the sample had at least one systemic disease (81.9%) and used at least one medication (79.2%). Female participants (p=0.01), those with five or more systemic diseases (p<0.01), and hypertension (p=0.04) had reduced salivary flow. Participants with systemic diseases (p=0.02), taking any medication (p=0.04), in a polypharmacy regimen, and presenting hypertension (p=0.02) had more acidic salivary pH. Participants with diabetes had average salivary buffering capacity (p=0.02). In the adjusted multiple regression models, no explanatory variable was significantly associated with the salivary outcomes. Conclusion: Systemic alterations and medication use appear to be related to salivary changes in older adults. Integrative assessment of older adults is fundamental to identifying and controlling the factors that may modify their salivary characteristics.

ABSTRACT

Aim: To carry out a retrospective analysis of the frequency and severity of clinical signs of radioiodine (131I)-induced damage to the salivary glands in the early and long-term post-radiation periods, and identify risk factors for their occurrence in patients with differentiated thyroid carcinomas. Methods: A total of 330 patients underwent thyroidectomy with dissection of lymphatic nodes. One month after surgery, all the patients received radioiodine therapy. The dose and number of courses varied depending on the stage and morphological type of the tumor. In the late post-radiation period, the patients were surveyed with the use of a standard questionnaire, which allowed retrospective assessment of the nature and severity of symptoms of radiationinduced damage, as well as the time of their onset/subsidence. Results: Radiation-induced sialoadenitis of the salivary glands was observed in 51.2% of patients treated with 131I. The main symptoms included pain and discomfort in the salivary glands (51.2% of patients), swelling (48.8%), transient or permanent dry mouth (38%), and distortion of taste (38%). There were statistically significant correlations between the presence and severity of the main clinical symptoms of salivary gland irradiation. A significant relationship (r = 0.91, p < 0.001) was found between swelling of the salivary glands and the feeling of pain or discomfort, which was indicative of inflammation and retention of saliva. Conclusion: The main factors influencing the formation of chronic radiation-induced sialoadenitis and the severity of the inflammatory process included the tumor stage, the total dose of radiopharmaceuticals, and the duration following radioiodine therapy

ABSTRACT

RESUMO Objetivo Verificar os efeitos imediatos da fotobiomodulação na produção do fluxo salivar e a correlação dos dados demográficos, antropométricos e de uso de medicamentos. Método Participaram do estudo 100 indivíduos saudáveis, com idade entre 18 e 76 anos (média 27,2 anos), divididos de forma randomizada em grupo experimental e grupo placebo. Foram realizadas as avaliações das medidas antropométricas, autopercepção da produção de saliva e a sialometria. Na sequência, realizou-se a irradiação do LASER no comprimento de onda infravermelho (808 nanômetros) com 100 miliwatts (mw) de potência em cinco pontos intraorais: nas glândulas sublingual e bilateralmente nas submandibulares e parótidas, nas doses 9, 18 e 24 joules (J). A sialometria foi repetida após cada aplicação. O grupo controle recebeu os mesmos procedimentos com equipamento placebo. Resultados Houve associação estatística na autopercepção de redução da saliva no grupo experimental para a dose de 24J e na sialometria e na redução do fluxo salivar para as doses 18J e 24J e aumento para 9J, em ambos os grupos. Não houve associação quando comparado entre os grupos experimental e placebo. A análise de regressão multinomial múltipla revelou que a redução ou o aumento do fluxo salivar independe das variáveis demográficas, antropométricas e uso de medicamentos. Conclusão A ação bioinibitória da fotobiomodulação sobre as glândulas salivares saudáveis ocorreu em dose de 18J e 24J, já ação bioestimulante na dose 9J, independe das variáveis demográficas, antropométricas e uso de medicamentos. A autopercepção da redução do fluxo salivar ocorreu em 24J.


ABSTRACT Purpose To verify the immediate effects of photobiomodulation on the production of salivary flow and the correlation of demographic, anthropometric and medication use data. Methods The study included 100 healthy individuals, aged between 18 and 76 years (mean 27.2 years), randomly split into an experimental group and a placebo group. Assessments of anthropometric measurements, self-perception of saliva production and sialometry were performed. Next, LASER irradiation was carried out at an infrared wavelength (808 nanometers) with 100 milliwatts (mw) of power at five intraoral points: on the sublingual glands and bilaterally on the submandibular and parotid glands, at doses of 9, 18 and 24 joules (J). Sialometry was repeated after each application. The control group received the same procedures with placebo equipment. Results There was a statistical association in the self-perception of reduced saliva in the experimental group for the 24J dose and in sialometry and in the reduction in salivary flow for the 18J and 24J doses and an increase to 9J, in both groups. There was no association when comparing the experimental and placebo groups. Multiple multinomial regression analysis revealed that the reduction or increase in salivary flow is independent of demographic, anthropometric and medication use variables. Conclusion The bioinhibitory action of photobiomodulation on healthy salivary glands occurred at a dose of 18J and 24J, while the biostimulant action happened at a dose of 9J, regardless of demographic, anthropometric variables and medication use. The self-perception of reduced salivary flow occurred at 24J.

ABSTRACT

ABSTRACT Objective: To determine the occurrence of hyposalivation in Brazilian adults and its association with individual determinants, such as the use of medications, systemic conditions, smoking, and alcohol consumption. Material and Methods: A cross-sectional study with 402 adults was developed. Information was collected on sociodemographic and general health characteristics, and sialometry was performed with stimulated salivary flow. It indicated low salivary flow when ≤ 0.7 mL/min. Bivariate and multivariate analyses were conducted using a decision tree (p<0.05). Results: The sample was comprised predominantly of women (68.2%) aged ≤ 29 years (25.4%). Most participants did not use medication (56.7%). Among systemic diseases, the most cited was hypertension (25.1%). More than a third of the participants presented hyposalivation (40.3%), being associated with the following variables: age between 50 to 59 years (p=0.011), female sex (p<0.001), menopause (p=0.001), use of alcohol (p=0.033), systemic disease (p=0.002) and medication use (p<0.001). In multivariate analysis, in addition to sex (p<0.001) and hypertension (p=0.005), an association was also found between hyposalivation and diabetes (p=0.014). Conclusion: Factors associated with hyposalivation in adults were sex and the presence of hypertension or diabetes.

ABSTRACT

Introduction: COVID-19 continues to drive research aimed at elucidating the disease's behavior and clinical aspects for improved diagnosis. Objective: To describe oral manifestations reported through a survey by dentate and denture-wearing Cuban individuals hospitalized due to confirmed COVID-19 infection. Methods: A cross-sectional descriptive study was conducted through a survey, involving Cuban individuals aged 18 years and above, confirmed COVID-19 positive by PCR. Exclusions encompassed smokers, alcoholics, regular medication users, those with poor oral hygiene, and individuals with pre-existing oral manifestations. A questionnaire was administered to over a thousand individuals, of which 264 met the criteria. Variables related to COVID-19 infection and oral hygiene were assessed. Data were processed using SPSS, adhering to ethical principles. Results: The study comprised 264 participants with an average age of 39.96 years. Xerostomia emerged as the most prevalent oral manifestation (40.2 por ciento), followed by mandibular pain, TMJ, or bone pain (18.9 por ciento), and non-dental mouth pain (12.5 por ciento). Xerostomia was more prevalent in the 35 to 39 age group, while mandibular pain predominated in the 50 to 54 age group. No statistically significant evidence was found for dentate individuals or denture wearers, but significance was observed for those requiring hospitalization, exhibiting painless tongue lesions, single ulcers, and painful tongue lesions. Conclusions: Xerostomia was the most prevalent oral manifestation, followed by mandibular pain, TMJ or bone pain, and non-dental mouth pain. A statistically significant association was noted between the need for hospitalization and certain oral manifestations. The use of dentures was not significantly related to the studied manifestations(AU)

ABSTRACT

Xerostomia, a term used to characterize the sensation of dry mouth, it is one of the most common symptoms after radiotherapy treatment of the head and neck region, being also the most expensive, impacting the oral health and quality of life of these patients. We performed a systematic review to identify topical treatments of natural composition in patients with radiation induced xerostomia. Searches were carried out in electronic databases such as the databases consulted were Cochrane library, PubMed (MEDLINE) and Latin American and Caribbean Literature in Health Sciences ­ LILACS. The research was carried out from June to July 2022 the period admitted for the results were from 1990 to 2022. We included trials of topical interventions with natural composition such, medicinal mucilage, sprays, oils and chewing gums for the management of dry mouth symptom. Results: 6 studies fully met the desired criteria, totalizing 336 patients. The therapies based on natural products were compared with placebo or other treatments and the forms of presentation were spray, oil, medicinal mucilage, and gel. In general, there was an improvement in some signs and symptoms of xerostomia and the most described adverse effect was nausea. Natural composition products seem to be a good alternative therapy for the relief of xerostomia symptoms and their consistency and form of application seem to exert influence, as evidence is still scarce, more randomized and placebo-controlled clinical studies are needed.


A xerostomia é o termo utilizado para caracterizar a sensação de boca seca, sendo um dos sintomas mais comuns após o tratamento radioterápico da região de cabeça e pescoço e também o mais oneroso, impactando na saúde bucal e na qualidade de vida desses pacientes. Realizamos uma revisão sistemática para identificar tratamentos tópicos de composição natural em pacientes com xerostomia induzida por radiação. As buscas foram realizadas em bases de dados eletrônicas, sendo que as bases de dados consultadas foram a biblioteca Cochrane, PubMed (MEDLINE) e Literatura Latino-Americana e do Caribe em Ciências da Saúde ­ LILACS. A pesquisa foi realizada de junho a julho de 2022, o período admitido para os resultados foi de 1990 a 2022. Incluímos ensaios de intervenções tópicas com composição natural como mucilagem medicinal, sprays, óleos e gomas de mascar para o manejo do sintoma de boca seca. Nos resultados 6 estudos preencheram totalmente os critérios desejados, totalizando 336 pacientes. As terapias baseadas em produtos naturais foram comparadas com placebo ou outros tratamentos e as formas de apresentação foram spray, óleo, mucilagem e gel. Em geral, houve melhora de alguns sinais e sintomas da xerostomia e o efeito adverso mais descrito foi a náusea. Os produtos de composição natural parecem ser uma boa alternativa terapêutica para o alívio dos sintomas da xerostomia e sua consistência e forma de aplicação parecem exercer influência, como as evidências ainda são escassas, são necessários mais estudos clínicos randomizados e controlados por placebo.

ABSTRACT

Objective:To understand the cognition and practice of nurses in anesthesia and resuscitation room on patients with xerostomia after general anesthesia, and to provide reference for improving xerostomia.Methods:This was a phenomenological research methods in qualitative research. From January to March 2021, the purpose of sampling method was used to select 10 nurses in anesthesia and recovery rooms from 3 grade A tertiary hospitals in Jinan City, Shandong Province as the research objects. The 7-step Colaizzi analysis method was used to analyze the data and refines the themes.Results:A total of 2 themes and 8 sub-themes were extracted: cognition of the practice process of patients with xerostomia (high recognition and affirmation, support for patients to participate in xerostomia management, focus on children with xerostomia), obstructive factors during practice of patients(intensive nursing human resources, lack of practice atmosphere, lack of standardized assessment tools, incomplete management measures, insufficient nurses′ self-efficacy).Conclusions:Nurses in anesthesia and resuscitation room play a guiding role in the management of patients with xerostomia after general anesthesia. It is necessary to understand nurses′ cognition of xerostomia and the factors that affect their practical behavior in order to supply reference to formulate scientific and systematic management system for xerostomia patients.

ABSTRACT

Objective:To analyze the dosimetric differences between 3D printed oral stents and corked oral stents in the target area and perioral organ at risk (OAR) in radiotherapy for head and neck cancer, and the effectiveness in reducing acute adverse reactions associated with radiotherapy.Methods:A total of 58 patients with head and neck cancer admitted to Department of Oncology of Affiliated Hospital of North Sichuan Medical College were selected and divided into experimental group (Group A, n=28, wearing 3D printed oral stents during radiotherapy) and control group (Group B, n=30, wearing corked oral stents during radiotherapy) in this retrospective cohort study. The incidence of radiotherapy - induced oral mucositis (RTOM), xerostomia and oropharyngeal mucosal pain was compared between two groups. Meanwhile, informed consent was obtained from 21 patients in Group A. Using the self control method, each patient wore a 3D printed oral stent (Group C) and a corked oral stent (Group D) to make two radiotherapy plans. The differences in the conformity index (CI), homogeneity index (HI) and exposure dose of OAR (D max, D mean) in the target area were analyzed between two groups. SPSS 25.0 statistical software was used for statistical analysis. Measurement data were expressed as Mean±SD. Comparison between two groups was conducted by paired t-test or repeated measurement analysis. Count data were expressed as ratio. Comparison between two groups was performed by Chi - square test or Fisher's exact test. P<0.05 was considered as statistically significant difference. Results:The severity of RTOM ( P<0.05), oropharyngeal mucosal pain ( P=0.004) and xerostomia score ( P<0.001) in Group A were significantly lower than those in Group B. There was no significant difference in the HI and CI of the target area between Group C and Group D (both P>0.05). The D max ( P=0.014, 0.009) and D mean ( P<0.001, P=0.033) of the upper lip and the affected buccal mucosa in Group C were significantly lower than those in Group D. Conclusion:3D printed oral stents obtain favorable HI and CI in radiotherapy for head and neck cancer, significantly reduce the irradiated dose to perioral OAR, and effectively lower the incidence and mitigate the severity of acute RTOM, xerostomia and oropharyngeal mucosal pain associated with radiotherapy.

ABSTRACT

Objective:To explore the effect of clinical target volume (CTV) optimization on long-term survival and late xerostomia of patients with nasopharyngeal carcinoma (NPC).Methods:Clinical data of 763 patients with NPC treated with intensity-modulated radiotherapy (IMRT) in the Jiangsu Cancer Hospital from January 2015 to November 2018 were retrospectively analyzed. All patients were divided into the modified and conventional CTV groups. Propensity score matching (PSM) was applied to balance the distribution of baseline features. The degree of xerostomia was evaluated by Radiation Therapy Oncology Group (RTOG) / European Organisation for Research and Treatment of Cancer (EORTC) standard and Jiangsu Cancer Hospital Multi-dimensional Radiotherapy-Induced Xerostomia scale. Survival analysis was performed by Kaplan-Meier method. The difference of xerostomia between two groups was compared by rank-sum test. The dose parameters of salivary glands were compared by independent sample t-test. Prognostic factors of survival and xerostomia were assessed by univariate / multivariate regression analyses. Results:There were no significant differences in overall survival, local recurrence-free survival, distant metastasis-free survival and progression-free survival between conventional and modified CTV groups before and after PSM. There were no significant differences in the incidence of late xerostomia above grade 2 of RTOG/EORTC standard between two groups. Using multi-dimensional scale criteria, NPC patients in the modified CTV group developed less late xerostomia than those in the conventional CTV group ( P<0.05). D mean and V 26 Gy of bilateral parotid glands, D mean and V 39 Gy of bilateral submandibular glands, and D mean of sublingual glands and mouths were reduced after optimization of CTV (all P<0.001). Univariate analysis showed that clinical staging, T staging and N staging were the independent prognostic factors of overall survival. Multivariate analysis demonstrated that clinical staging was the independent prognostic factor of overall survival. The risk factor for xerostomia during night sleep was the D mean of sublingual glands. Conclusion:The optimization of CTV in IIb region in NPC treated with IMRT can better protect salivary glands and reduce the incidence of late radiation-induced xerostomia on the premise of ensuring long-term survival.

ABSTRACT

Xerostomia is defined as the perception of dry mouth, and dysgeusia, as a change in taste. Both are common complaints in the elderly, especially among those making use of polypharmacy drug combinations. Aim: This study aimed to determine the prevalence of xerostomia and dysgeusia and to investigate their association with polypharmacy in the elderly. Methods: older people under follow-up at the Multidisciplinary Elderly Center of the University Hospital of Brasília were interviewed and asked about health problems, medications used, presence of xerostomia and dysgeusia. Descriptive statistics were used to determine the prevalence of the symptoms surveyed. The chi-square test was used to investigate the relationship between xerostomia and dysgeusia and polypharmacy. Secondary associations were performed using binomial logistic regression. Results: Ninety-six older people were evaluated and of these, 62.5% had xerostomia and 21.1%, had dysgeusia. The average number of medications used was 4±3 medications per individual. Polypharmacy was associated with xerostomia but not dysgeusia. It was possible to associate xerostomia with the use of antihypertensive drugs. Conclusion: Xerostomia was a frequent complaint among elderly people making use of polypharmacy, especially those using antihypertensives. Antihypertensives and antidepressants were used most drugs by the elderly and exhibited interactions with drugs most prescribed in Dentistry. Two contraindications were found between fluconazole and mirtazapine; and between erythromycin and simvastatin

ABSTRACT

Aim: To evaluate the impact of xerostomia, edentulism, use of dental prosthesis, and presence of chronic diseases on quality of life in relation to oral health in institutionalized elderly individuals. Methods: This is a cross-sectional study. A questionnaire was administered containing the following instruments: Oral Health Impact Profile (OHIP-14), which measures the quality of life related to oral health; the Summated Xerostomia Inventory questionnaire (SXI-PL) for evaluation of xerostomia, sociodemographic data, clinical description, and patient-reported factors was assessed (edentulism, use of dental prostheses, and chronic diseases). Results: Most elderly individuals did not have any teeth in their mouths and used dental prosthesis. The impact on quality of life, considering the mean of the OHIP-14 scores, was positive in 58.3% of the elderly. Those who used a dental prosthesis were three times more likely to have their oral health negatively impacted (OR=3.09; 95%CI =1.17 8.11), compared to those who did not use, and individuals with xerostomia were more likely to have their oral health negatively impacted (OR=1.57; 95%CI=1.25-1.98) compared to those without xerostomia. There was no difference in the quality of life of individuals with and without chronic diseases. Conclusions: The feeling of dry mouth and use of dental prostheses negatively impacted the quality of life in relation to oral health of the elderly

ABSTRACT

ABSTRACT Objective: This two-centre cross-sectional study aimed to evaluate whether xerostomia occurrence is associated with oral health-related quality of life (OHRQoL) in patients with end-stage renal disease (ESRD) after the adjustment for potential confounders. Methods: Oral examinations were performed by calibrated examiners for untreated dental caries, periodontitis and tooth loss in 180 adults with ESRD. The presence of xerostomia was determined using the global question "How often does your mouth feel dry?". OHRQoL was evaluated by the simplified version of the Oral Health Impact Profile (OHIP14) questionnaire. Multivariate zero-inflated negative binomial regression analysis was used to calculate the incidence rate ratios (IRR) for the nonzero scores and odds ratios (OR) of having no impact in OHIP14 scores according to the presence of exposure. Results: In the adjusted model, xerostomia (IRR = 1.57; 95% CI: 1.12 to 2.20) was associated with poorer OHRQoL. The adjusted domain-specific analysis revealed that xerostomia occurrence significantly impacted the psychological disability and social disability, and the chance of having no impact was lower for the psychological discomfort domain (OR = 0.84; 95% CI: 0.12 to 0.98). Conclusion: Xerostomia exert an impact on OHRQoL in patients with ESRD, mainly in the psychological and social disabilities constructs.


RESUMO Objetivo: Este estudo transversal realizado em dois centros teve como objetivo avaliar se a ocorrência de xerostomia está associada à qualidade de vida relacionada à saúde bucal (QVRSB) em pacientes com doença renal crônica em estágio final (DRCEF) após o ajuste para potenciais fatores de confusão. Métodos: Exames bucais foram realizados por examinadores calibrados para cárie dentária não tratada, periodontite e perda dentária em 180 adultos com DRCEF. A presença de xerostomia foi determinada por meio da pergunta global "Com que frequência você fica com a boca seca?". A QVRSB foi avaliada pela versão simplificada do questionário Oral Health Impact Profile (OHIP-14). A análise multivariada de regressão binomial negativa inflacionada por zero foi usada para calcular as taxas de incidência (IRR) para os escores diferentes de zero e os razões de chance (OR) de não haver impacto nos escores do OHIP-14 de acordo com a presença dA exposição. Resultados: No modelo ajustado, a xerostomia (IRR = 1,57; IC 95%: 1,12 a 2,20) foi associada a pior QVRSB. A análise específica por domínio revelou que a ocorrência de xerostomia impactou significativamente a incapacidade psicológica e a incapacidade social, e a chance de não haver impacto foi menor para o domínio desconforto psicológico (OR = 0,84; IC95%: 0,12 a 0,98). Conclusão: A xerostomia exerce impacto sobre a QVRSB em pacientes com DRCEF, principalmente nos construtos de deficiência psicológica e social.

ABSTRACT

The objective of this study was to evaluate whether individuals with chronic renal failure (CRF) undergoing hemodialysis treatment have more salivary and oral mucosa alterations when compared to healthy individuals, through a systematic review followed by meta-analysis. A systematic literature review was performed, evaluating randomized clinical trials found in the Proquest, Embase, Scopus, Cochrane Library, Web of Science, Lilacs and Pubmed databases, using MeSH terms and other keywords. Initially, 40 articles were included in the study and, after reading the complete articles, only 15 clinical trials that analyzed oral lesions and salivary changes in patients with CRF undergoing hemodialysis treatment were eligible. Most of the clinical studies included were cross-sectional and composed of a study group and a control group. The mean age of participants in the study group was 50.19 years and in the control group, 48.95 years. The most common oral alterations found in the CRF group in relation to the control group were xerostomia, uremic breath, dysgeusia, coated tongue, gingival bleeding and pale mucosa. The salivary flow of patients with CRF was 46.6% lower than the control group. The salivary pH in the study group was also more alkaline when compared to the control group. Greater amounts of urea, phosphate, C-reactive protein and total proteins were found in the saliva of individuals with CRF. Individuals with CRF undergoing hemodialysis are more prone to changes in both the quantity and quality of saliva, as well as having a greater amount of oral changes.

ABSTRACT

El síndrome de Sjögren es la segunda enfermedad autoinmune crónica más prevalente; factores hereditarios y medioambientales interactúan provocando una "epitelitis autoinmune" que daña el tejido glandular exocrino principalmente, pero también a otros órganos; debido a esta heterogeneidad clínica, el diagnóstico y tratamiento constituyen un desafío. Estudios demuestran que afecta al 0,1-0,6 % de la población, con predilección por el sexo femenino (9:1). En Colombia existen pocos estudios epidemiológicos descriptivos y de caracterización en este síndrome. Caracterizar los parámetros clínicos y epidemiológicos de pacientes con síndrome de Sjögren. Se realizó un estudio observacional descriptivo de corte transversal, se revisaron historias clínicas de 409 pacientes con el síndrome que asistieron al Hospital Universitario San Ignacio entre 2012 y 2019. Los datos se analizaron usando estadística descriptiva. La edad promedio de diagnóstico fue 59 años, la relación mujer: hombre 9:1, (91,7 % y 8,3 % respectivamente). Hubo mayor prevalencia en pacientes de 51 a 60 años (131) seguido por los de 61-70 años (114). La manifestación clínica más común fue la xerostomía (90 %); la biopsia de glándula salival menor fue el examen complementario más solicitado (65 %). El compromiso óseo-articular, fue la enfermedad concomitante más asociada. La etiología de la enfermedad es poco conocida, sin embargo, su caracterización, así como la identificación de medios diagnósticos y terapéuticos ayuda en la comprensión de la clínica; dicha información permitirá el desarrollo de tratamientos cada vez más efectivos y específicos.


Sjögren syndrome is the second most common chronic autoimmune disease, environmental and hereditary mechanisms causes an autoimmune epithelitis that affect the exocrine glandular tissue mainly, but also other organs; because this broad spectrum of clinical characteristics, the diagnostic and treatment become a challenge. Studies has shown that 0.1-0.6 % of the population is affected, with predominance of females over males (9:1). In Colombia there are few descriptive epidemiological studies and characterization of the affected population. Clinical and epidemiological characterization of Sjögren syndrome patients. A descriptive cross-sectional observational study was conducted, 409 clinical histories of patients with the syndrome at San Ignacio University Hospital from 2012 to 2019 were analized. The data collected were subjected to a descriptive statistic. The average age of diagnosis was 59 years, the ratio female: male 9:1 (91.7 % and 8.3 % respectively), the highest frequency of the syndrome was found in the 51 to 60 years old group (131) followed by the 61 to 70 years old group (114). The most common clinical manifestation was xerostomia (90 %), minor salivary gland biopsy was the most frequent test requested (65 %). The osseoarticular involvement was the most frecuent concomitant disease. Although the etiology of Sjögren syndrome is little known, its characterization, as well as the identification of the diagnostic and therapeutic means used, is of great help in understanding the disease; this information will allow the development of increasingly effective and specific treatments. More studies are required, in different locations, which will highlight the differences between populations.

ABSTRACT

Sjögren's syndrome is an entity of rheumatic origin, with complex autoimmune characteristics, in which the salivary and lacrimal glands are mainly compromised. It has two forms of presentation, one primary and the other secondary, and in both forms there is evidence of exocrine glands involvement. The clinical spectrum of Sjögren's syndrome is very heterogeneous and is classified into glandular and extra-glandular manifestations, but not mutually exclusive. It is recommended that all patients with parotid inflammation, purpura, hypergammaglobulinaemia, anti-SSa, and anti-SSb should be seen to have a greater risk of presenting with a severe systemic presentation, and it is recommended to carry out a more strict medical control. Population studies that have attempted to describe the incidence and prevalence of Sjögren's syndrome in various countries throughout the world are to some extent discordant between one registry and another. Although Sjögren's syndrome is more common in women, ocular involvement predominates in men, and it can occur in all ages, mainly between the third and fifth decades of life. In children it is rare. It is also considered as a common connective tissue disease, where the data on the global incidence rate and prevalence are underestimated.


El síndrome de Sjögren es una entidad de origen reumático, con características autoinmune complejas, en la que se ven comprometidas principalmente las glándulas salivales y las lagrimales. Tiene 2 formas de presentación, una primaria y otra secundaria, y en ambas se observa una afección de las glándulas exocrinas. El espectro clínico del síndrome de Sjögren es muy heterogéneo y se clasifica en manifestaciones glandulares y extraglandulares, no excluyentes entre sí. Se recomienda que se haga un control médico más estricto a todo paciente que curse con una inflamación parotídea, púrpura, hipergammaglobulinemia y anticuerpos anti-SSa, anti-SSb, puesto que presenta mayor riesgo de cursar con una presentación sistémica grave. Los estudios poblacionales que han intentado describir la incidencia y la prevalencia del síndrome de Sjögren en diferentes países son hasta cierto punto discordantes entre un registro y otro. El síndrome de Sjögren es más frecuente en mujeres, pero en hombres predomina más la afectación ocular; puede presentarse en todas las edades, principalmente entre la tercera y la quinta décadas de la vida; en niños es raro. Se considera además como una conectivopatía frecuente, en la cual los datos de la tasa de incidencia global y de prevalencia se encuentran subestimados.

ABSTRACT

Introdução: O manejo de pacientes com ardor bucal é um desafio no cotidiano clínico da odontologia. Objetivo: Comparar o efeito da Terapia a Laser de Baixa Intensidade (LLLT) e da Estimulação Elétrica Nervosa Transcutânea (TENS) no tratamento do ardor bucal. Metodologia: Ensaio clínico randomizado constituído por 25 pacientes com ardor bucal que foram tratados por TENS (n=12) e por LLLT (n=13). Os protocolos de tratamento foram aplicados semanalmente por 8 semanas. O teste análise de variância (ANOVA) dois fatores foi usado para verificar se existia diferença significativa entre os tempos T0 (antes de iniciar o tratamento), T1 (após a 4ª sessão de tratamento), T2 (após a 8ª sessão de tratamento) e T3 (30 dias após o término do tratamento) em relação aos sintomas, analisados por meio da Escala Visual Analógica (EVA), fluxo salivar não estimulado, xerostomia e disgeusia com as intervenções de TENS e LLLT. Resultados: A maioria dos pacientes foi do sexo feminino no período pós-menopausa com média de idade no grupo TENS de 59,25 anos e no grupo LLLT de 62,08. Hipertensão e dislipidemia foram as alterações sistêmicas mais frequentes. Ansiedade e depressão foram os únicos transtornos psiquiátricos relados. A maioria dos pacientes fazia uso de medicamentos como anti-hipertensivos e antidepressivos. Não foram observadas variações expressivas no que se refere a xerostomia e a disgeusia nos dois grupos analisados. A TENS e a LLLT foram eficazes na redução dos sintomas relatados pelos pacientes (p˂0,001), entretanto, observou-se entre os tempos T2 e T3 que o grupo LLLT apresentou uma melhor resposta quando comparado ao TENS (p=0,003). Os pacientes do grupo TENS apresentaram aumento do fluxo salivar entre os tempos T1 e T2, enquanto o grupo LLLT apresentou uma diminuição (p=0,052). Conclusão: A TENS e a LLLT foram eficazes na redução dos sintomas do ardor bucal durante o tratamento e 30 dias após o término do tratamento, sendo que o grupo LLLT apresentou uma melhor resposta na sessão de acompanhamento pós-tratamento quando comparado ao grupo TENS (AU).


Introduction: The management of patients with burning mouth is a challenge in the clinical routine of dentistry. Objective: To compare the effect of Low Intensity Laser Therapy (LLLT) and Transcutaneous Electrical Nerve Stimulation (TENS) in the treatment of burning mouth. Methodology: Randomized clinical trial consisting of 25 patients with burning mouth who were treated with TENS (n=12) and LLLT (n=13). Treatment protocols were applied weekly for 8 weeks. The two-way analysis of variance (ANOVA) test was used to verify whether there was a significant difference between the times T0 (before starting treatment), T1 (after the 4th treatment session), T2 (after the 8th treatment session) and T3 (30 days after the end of treatment) in relation to symptoms, analyzed using the Visual Analogue Scale (VAS), unstimulated salivary flow, xerostomia and dysgeusia with TENS and LLLT interventions. Results: Most patients were female in the postmenopausal period, with a mean age of 59.25 years in the TENS group and 62.08 in the LLLT group. Hypertension and dyslipidemia were the most frequent systemic alterations. Anxiety and depression were the only psychiatric disorders reported. Most patients used drugs such as antihypertensives and antidepressants. Significant variations were not observed with regard to xerostomia and dysgeusia in the two groups analyzed. TENS and LLLT were effective in reducing the symptoms reported by patients (p˂0.001), however, it was observed between times T2 and T3 that the LLLT group showed a better response when compared to TENS (p=0.003). Patients in the TENS group showed an increase in salivary flow between times T1 and T2, while the LLLT group showed a decrease (p=0.052). Conclusion: TENS and LLLT were effective in reducing the symptoms of burning mouth during treatment and 30 days after the end of treatment, and the LLLT group showed a better response in the posttreatment follow-up session when compared to the TENS group (AU).
