Ill-fitting prosthesis is associated with an increased risk of elevated blood pressures.

OBJECTIVE: Previous studies focused on the benefits of adequate prosthodontic treatment, while few studies have investigated the prosthodontic-related risks to health. As a modifiable oral health indicator, the association of ill-fitting prosthesis (IFP) with hypertension has not been fully explored. METHODS: This cross-sectional study involved 158,659 adults in Beijing (2009-2017) receiving intra-oral examinations and blood pressure measurements. Logistic regression models were applied to assess the association of IFP with the prevalence of hypertension, systolic blood pressure (SBP) ≧ 140 mmHg and diastolic blood pressure (DBP) ≧ 90 mmHg, as well as subgroup analyses by different fixed IFP subgroups (according to involved teeth number) and removable IFP subgroup. We further investigated effect modifications among stratified populations. RESULTS: 158,659 individuals were included for analysis, 346 (26.86%) in IFP group and 27,380 (17.40%) in non-IFP group (p < 0.001) were hypertensive. After adjustment of sex, age, obesity, dyslipidaemia, diabetes, hsCRP, family history of CVD, self-reported smoking, self-reported drinking and WC, ORs of hypertension, SBP ≧ 140 mmHg and DBP ≧ 90 mmHg were 1.330 (95% CI: 1.162-1.522), 1.277 (95% CI: 1.098-1.486) and 1.376 (95% CI: 1.186-1.596), respectively (p < 0.05). Furthermore, after full adjustment, the number of involved teeth showed a significant incremental trend with hypertension risk in the population with and without IFP (p for trend <0.001). The IFP-blood pressure associations were more pronounced in females, 18-60 years, non-obese and diabetic participants. CONCLUSION: As a modifiable oral indicator, IFP was significantly associated with a higher risk of hypertension.

A Rare Laryngeal Foreign Body Case: Postcricoid Total Dental Prosthesis.

In this case report, 60-year-old patient who aspirated total dental prosthesis into the postcricoid region was presented with patient's history, clinical findings, radiologic examinations and surgical treatment with comparison of literature data. To our literature knowledge, this is the first total dental prosthesis detected in postcricoid region. This was unusual because it did not cause any respiratory disorders such as laryngospasm and asphyxia, although it led to mucosal abrasions in a wide area of esophageus.

Dental prosthesis use is associated with higher protein intake among older adults with tooth loss.

BACKGROUND: Tooth loss is associated with reduced protein intake, which leads to sarcopenia and frailty in older adults. OBJECTIVE: To evaluate the protective effect of dental prostheses on decreased protein intake in older adults with tooth loss. METHODS: This cross-sectional study was based on a self-reported questionnaire targeting older adults. Data were obtained from the Iwanuma Survey of the Japan Gerontological Evaluation Study. We used % energy intake (%E) of total protein as the outcome and the use of dental prostheses and number of remaining teeth as explanatory variables. We estimated the controlled direct effects of tooth loss by fixing the use/non-use of dental prostheses based on a causal mediation analysis, including possible confounders. RESULTS: Among 2095 participants, the mean age was 81.1 years (1SD = 5.1), and 43.9% were men. The average protein intake was 17.4%E (1SD = 3.4) of the total energy intake. Among participants with ≥20, 10-19 and 0-9 remaining teeth, the average protein intake was 17.7%E, 17.2%E/17.4%E and 17.0%E/15.4%E (with/without a dental prosthesis), respectively. Compared to participants with ≥20 remaining teeth, those with 10-19 remaining teeth without a dental prosthesis did not have a significantly different total protein intake (p > .05). Among those with 0-9 remaining teeth without a dental prosthesis, total protein intake was significantly low (-2.31%, p < .001); however, the use of dental prostheses mitigated the association by 79.4% (p < .001). CONCLUSION: Our results suggest that prosthodontic treatment could contribute to maintaining protein intake in older adults with severe tooth loss.

Chronic mechanical irritation and oral squamous cell carcinoma: A systematic review and meta-analysis.

The objective of the present article was to qualitatively and quantitatively review the association between chronic mechanical irritation and oral squamous cell carcinoma (OSCC). PubMed, SCOPUS, and Web of Science databases were searched using the keyword combinations "chronic trauma and oral squamous cell carcinoma; chronic irritation and oral squamous cell carcinoma; chronic irritation and oral cancer; and chronic trauma and oral cancer." Duplicates and irrelevant articles were excluded after the title and abstract screening. The full texts of the remaining articles were assessed using selection criteria. A total of 375 (PubMed-126; SCOPUS-152; WOS-97) articles were screened, and 343 duplicates and irrelevant articles were excluded from the study. Only 9 of the remaining 32 articles met the selection criteria and were included in the qualitative analysis. Buccal mucosa and tongue, being highly prone to chronic irritation through the dental prosthesis, were the common sites for OSCC. Edentulous subjects with ill-fitting dentures were at a high risk of developing chronic irritation associated-OSCC. According to the Joanna Briggs Institute of risk assessment, eight of the nine included studies had a low risk of bias. The quantitative analysis showed a significant association (p < 0.00001) between the chronic oral mucosal irritation and OSCC with an overall risk ratio of 2.56 at a confidence interval of 1.96-3.35. Chronic oral mucosa irritation has a significant association with OSCC, and the nature of association could be that of a potential co-factor (dependent risk factor) rather than an independent risk factor.

Presencia de bacterias en prótesis dentales durante el proceso de elaboración / Presence of bacteria in dental prostheses during the elaboration process

Existe una creciente preocupación sobre el tema de la infección cruzada en clínicas y laboratorios dentales. El laboratorio odontológico debe seguir normas de bioseguridad que garanticen a todo el equipo de salud la prevención de estas infecciones. Los técnicos que allí laboran corren el riesgo de exponer su cara a salpicaduras, así como a rocíos de sangre y saliva. Este estudio fue diseñado para saber si los laboratorios a los que recurrimos cumplen con estas normas de bioseguridad, y qué tan confiados podemos estar de la desinfección por parte de ellos, ya que las prótesis deberían estar desinfectadas correctamente antes de colocarlas en boca (AU)

There is growing concern about the issue of cross infection in dental clinics and laboratories. The dental laboratory must follow biosafety standards that guarantee the prevention of these infections to the entire health team. The technicians who work there run the risk of exposing their face to splashes and spray of blood and saliva. This study was designed to find out if the laboratories we use comply with these biosafety standards, and how confident we can be of their disinfection by them, since the prostheses should be properly disinfected before placing them in the mouth (AU)

Factores de riesgo relacionados con las lesiones paraprotésicas en pacientes portadores de prótesis removibles / Risk factors related to the paraprosthetic lesions in patients with removable prosthesis

Introducción: Las lesiones paraprotésicas son alteraciones de la mucosa bucal asociadas al uso de prótesis dental, las cuales pueden provocar complicaciones graves. Objetivo: Identificar los factores de riesgo relacionados con las lesiones paraprotésicas en pacientes portadores de prótesis removibles. Métodos: Se realizó un estudio observacional y descriptivo de 180 pacientes con lesiones paraprotésicas, atendidos en la Clínica Estomatológica Provincial Docente Mártires del Moncada de Santiago de Cuba, desde febrero del 2019 hasta mayo del 2020. Se seleccionaron las siguientes variables: edad, sexo, factor de riesgo y tipo de lesión paraprotésica. Resultados: Predominaron los pacientes de 60 años y más, la estomatitis subprótesis (52,7 %) y factores de riesgo, tales como prótesis mucosoportada, mayor tiempo de uso, así como hábito de dormir con la prótesis. Conclusiones: La lesión paraprotésica más frecuente fue la estomatitis subprótesis debido a la persistencia de los mismos factores de riesgo, que incidieron en la población a través del tiempo.

Introduction: Paraprosthetic lesions are alterations of the oral mucosa associated with the use of dental prosthesis, which can cause serious complications. Objective: To identify the risk factors related to the paraprosthetic lesions in patients with removable prosthesis. Method: An observational and descriptive study of 180 patients with paraprosthetic lesions was carried out; they were assisted in Mártires del Moncada Teaching Provincial Stomatological Clinic in Santiago de Cuba, from February, 2019 to May, 2020. The following variables were selected: age, sex, risk factor and type of paraprosthetic lesion. Results: There was a prevalence of the 60 years and over patients, sub prosthesis stomatitis (52.7 %) and risk factors, such as mucosoported prosthesis, longer time using it, as well the habit of sleeping with the prosthesis. Conclusions: The most frequent paraprosthetic lesion was the sub prosthesis stomatitis due to the persistence of the same risk factors that impacted in the population through the time.

Cytomorphometric Analysis of Inflammation Dynamics in the Periodontium Following the Use of Fixed Dental Prostheses.

Cytomorphometry is used in the sampling of biological materials and diagnostic procedures. The use of cytological studies in periodontal diseases is not well described in the literature. Our study aimed to quantitatively assess the inflammation dynamics using cytomorphometric analysis of the periodontium before and after the use of fixed dental prostheses. Following ethics approval, a total of 105 subjects were divided in 3 groups as gingivitis (n = 23), periodontitis (n = 58), and healthy periodontium (control) (n = 24). The fixed dental prostheses (crowns and fixed partial dentures) were fabricated from cobalt-chrome metal-ceramic prostheses using the conventional method (C/M-CoCr), cobalt-chrome metal-ceramic prostheses by the computer-aided design and computer-aided manufacturing (CAD/CAM) technique (C/C-CoCr), and zirconia-based ceramic prostheses by the CAD/CAM technique (C/C-Zr) among subjects with gingivitis and periodontitis. The gingival crevicular fluid (GCF) was obtained from subjects before and after the use of the prostheses. The total count of epithelial cells and the connective tissue cells or polymorphonuclear neutrophils (PMNs) in GCF were studied using cytomorphometric analysis. The Statistical Package Tor the Social Sciences (SPSS), Version 20 (IBM Company, Chicago, IL, USA) was used to analyze the results and the significance level was set at p = 0.05. The data for before and after the use of the prostheses were compared using independent t-Tests. Similarly, the results after the use of prostheses in gingivitis, periodontitis, and control in each type of prostheses were compared using One-way ANOVA with post hoc using Scheffe. The total epithelial cells and the PMNs were determined along with the epithelium/leukocyte index. Regardless of the prostheses type used, no significant change in the parameters was identified among patients with a healthy periodontium, before and after prosthetic treatment. In all study groups, a statistically increase (p value < 0.05) was observed in the oral epithelial cell counts and a statistically decrease (p < 0.05) in the PMNs count following the use of the fixed prostheses. Data on cytomorphometric analysis could enable the selection of the most appropriate prostheses for use in patients with periodontal pathologies. When choosing prostheses, changes in the composition of GCF could be considered as a useful criterion for their use.

Efficacy of silicone soft reliner on the obturator prosthesis after maxillectomy for oral malignant tumors: A single-arm prospective interventional study.

BACKGROUND: There is insufficient evidence for the efficacy of silicone soft reliner on the obturator prosthesis after maxillectomy for oral malignant tumors. OBJECTIVE: To verify the efficacy of silicone soft reliner on the obturator prosthesis after maxillectomy, by evaluating masticatory performance and quality of life (QoL). METHODS: This was a single-arm prospective interventional study, verifying the efficacy of silicone soft reliner (GC RELINE II®) on the maxillary obturator prosthesis. Data were obtained from a comparison of the endpoints after 14 days of continuous use of acrylic and silicone soft-lined prostheses. The primary endpoint was masticatory performance. The secondary endpoints were occlusal performance and oral health-related QoL (OHRQoL). The masticatory performance, occlusal performance, and OHRQoL were assessed by glucose concentration, maximum bite force, and the Japanese version of Oral Health Impact Profile (OHIP-J49), respectively. RESULTS: This study included five patients (two males, three females), aged between 71 and 88 years, with a median of 74 years. The median of glucose concentration indicated a statistically significant improvement between the acrylic resin (99.6 mg/dL) and silicone soft reliner (126.0 mg/dL) obturator prosthesis (p = .043). There was no significant difference in the median of maximum bite force between the acrylic resin (302.0 N) and silicone soft reliner (250.0 N) obturator prosthesis (p = .893). Functional limitations domain of the OHIP-J49 indicated a statistically significant improvement between the acrylic resin and silicone soft reliner obturator prosthesis (p = .043). CONCLUSIONS: This study indicated that an obturator relined with soft silicone improved masticatory performance and the OHRQoL post-maxillectomy.

Denture stomatitis associated with small-colony variants of Staphylococcus aureus: a case report.

BACKGROUND: The small-colony variants (SCVs) of Staphylococcus aureus were isolated from persistent and recurrent infections, especially after placement of medical devices having direct contact with human tissues. The emergence of SCVs is a survival strategy of S. aureus which enables them to hide inside host's cells and induces a less severe immune response than to wild-type S. aureus. However, contrary to other medical devices, dental prosthesis as a surface potentially colonized by SCVs of S. aureus has not been examined thus far. We reported the first case of SCVs - S. aureus infection in denture wearer. CASE PRESENTATION: A 62-year-old woman with a complete removable acrylic denture presented extensive elevated erythematous lesions on the palate, compatible with denture stomatitis. The patient had a history of arterial hypertension, cigarette smoking and wearing denture at night. The fungal colonies, identified as Candida albicans, were cultured on Sabouraud agar. From three swabs (from hard palate mucosa, denture surface and angular cheilitis lesions) were cultured of pinpoint, clear, non-pigmented, and non-haemolytic colonies on Columbia agar. The small colonies turned out to be Gram-positive cocci, catalase-, Pastorex Staph Plus -, and clumping factor-positive, and oxidase-negative. Suspected phenotypically SCVs forms were definitively identified as S. aureus based on PCR amplification of species specific nuc and coa genes. Methicillin-resistance was verified by mecA gene detection. The isolates turned out to be susceptible to methicillin (MSSA) and resistant to gentamicin. The isolate was identified as menadione-auxotrophic variant. CONCLUSIONS: This case demonstrated that oral cavity in denture wearers may be a reservoir of small-colony variants of S. aureus, besides C. albicans. The prevalence of these bacteria and their role in the pathogenesis of oral diseases are not understood. Due to problems with their detection and identification, the true prevalence of oral SCVs may be underestimated.

La prótesis estomatológica como factor de riesgo de lesiones premalignas y malignas en la cavidad bucal / The dental prosthesis as a risk factor for premalignant and malignant lesions in the oral cavity

Fundamento: la ubicación de cualquier tipo de prótesis dental en la boca provoca inevitables variaciones en el medio bucal, que obliga a los tejidos a reaccionar para adaptarse ante nuevas situaciones donde puede llegar a originarse lesiones consideradas como malignas o premalignas. Objetivo: describir la influencia de las prótesis estomatológicas como factor de riesgo para la aparición de lesiones premalignas y malignas en la cavidad bucal. Métodos: se realizó un estudio descriptivo transversal en el Policlínico Docente Manuel Antonio de Varona Miranda del municipio Sibanicú, provincia Camagüey en el periodo de enero 2016 hasta abril 2018. El universo de estudio estuvo constituido por 88 pacientes portadores de prótesis totales y parciales acrílicas remitidos con sospechas de lesiones premalignas o malignas. Resultados: el 57,9 porciento de las lesiones premalignas o malignas se desarrollaron en el reborde alveolar residual. De las prótesis en uso el 77,2 porciento se encontraban desajustadas y el 23,8 porciento presentó algún tipo de fractura. Solo el 18,7 porciento de los aparatos protésicos se estaban higienizados y el 43,7 porciento de los pacientes de la muestra usaban sus prótesis durante 24 horas. Conclusiones: la mayoría de las lesiones se desarrollaron en el reborde alveolar residual. Una gran parte de los aparatos protésicos en uso no se higienizaban bien, se usaban durante 24 horas y presentaban un estado técnico inadecuado (AU)

Background: the location of any type of dental prosthesis in the mouth causes unavoidable variations in the oral environment, which forces the tissues to react to adapt to new situations and it may cause lesions considered malignant or premalignant. Objective: to describe the influence of dental prostheses as a risk factor for the appearance of premalignant and malignant lesions in the oral cavity.Methods: a cross-sectional descriptive study was carried out in the Manuel Antonio de Varona Miranda Teaching Polyclinic of the Sibanicú municipality, in Camagüey province, from January 2016 to April 2018. The universe of study consisted of 88 patients with total and partial acrylic prostheses, referred with suspicion of premalignant or malignant lesions.Results: 57.9 percent of premalignant or malignant lesions developed in the residual alveolar ridge. Of the prostheses in use, 77.2 percet were out of adjustment and 23.8 percent had some type of fracture. Only 18.7 percent of the prosthetic devices were properly sanitized and 43.7 percent of the patients in the sample used their prostheses for 24 hours. Conclusions: the majority of the lesions were developed in the residual alveolar ridge. A large part of the prosthetic devices in use were not sanitized well, they were used for 24 hours and had an inadequate technical condition (AU)

Autoperception of food conditions of elderly dental prosthetic users. / Autopercepção das condições alimentares de idosos usuários de prótese dentária.

PURPOSE: To evaluate the self-perception of the food conditions of elderly users of dental prosthesis, in order to verify the interference that dental prosthesis has in their feeding. METHODS: The present study counted with 60 elderly, participants of the Centro de Convivência Nair Ventorin Gurgacz (Community Center), aged between 60 and 88 years old. All participants answered to a questionnaire elaborated by the researchers and the Geriatric Oral Health Assessment Index (GOHAI). RESULTS: The elderly who participated in this study, mostly women, used a bimaxillary removable prosthesis for over 30 years; although they classified their nutrition as "good" and did not present preference for specific food consistency, they frequently felt pain while chewing. The average score of the GOHAI was 29.73, considered "low", the index dimension with worst score was physical function, that includes eating, speaking and swallowing. No relation was observed between time of use of dental prosthesis, age and the GOHAI scores. CONCLUSION: The elderly rarely complaint about discomfort or embarrassment on feeding, however, they present an average lower than expected in the GOHAI index, which indicates that, although they do not report it, many deteriorations, that seem to be natural may be happening and may be the cause of worst quality of life.

OBJETIVO: Avaliar a autopercepção das condições alimentares de idosos usuários de prótese dentária, verificando sua interferência na alimentação. MÉTODO: Participaram 60 idosos com idade entre 60 e 88 anos, usuários de prótese dentária total ou parcial, que frequentam assiduamente o Centro de Convivência Nair Ventorin Gurgacz ­ FAG em Cascavel, Paraná. Todos os indivíduos responderam a um questionário de identificação e ao protocolo Índice de Determinação da Saúde Bucal Geriátrica (GOHAI). RESULTADOS: Os idosos do estudo, maioria mulheres e usuários de prótese removível bimaxilar com mais de 30 anos, classificam sua alimentação como "boa" e não possuem preferência por consistência alimentar, embora frequentemente sintam dor ao mastigar os alimentos. A média pontuada no protocolo GOHAI foi classificada como "ruim" e o maior prejuízo dos idosos ocorreu no domínio físico, que engloba questões relacionadas à mastigação, deglutição e fala. Não foram constatadas relações entre o tempo de utilização da prótese dentária com a idade e os escores do GOHAI. CONCLUSÃO: Embora os idosos raramente tenham queixa sobre o modo de se alimentar, referindo desconforto ou constrangimento, apresentam uma média abaixo do esperado no protocolo, indicando que, ainda que não relatem, muitas modificações podem estar acontecendo, gradativamente, e que soam como naturais, gerando prejuízos à qualidade de vida em alimentação do idoso.

Predictive Factors of Swallowing Disorders and Bronchopneumonia in Acute Ischemic Stroke.

BACKGROUND: In stroke patients, early complications such as swallowing disorders (SD) and bronchopneumonia (BP) are frequent and may worsen outcome. The aim of this study was to evaluate the prevalence of SD in acute ischemic stroke (AIS) and the risk of BP, as well as to identify factors associated with these conditions. METHODS: We retrospectively studied all AISs over a 12-month period in a single-center registry. We determined the frequency of SD in the first 7 days and of BP over the entire hospital stay. Associations of SD and BP with patient characteristics, stroke features, dental status, and presence of a feeding tube were analyzed in multivariate analyses. RESULTS: In the 340 consecutive patients, the overall frequency of SD and BP was 23.8% and 11.5%, respectively. The multivariate analyses showed significant associations of SD with NIHSS scores >4, involvement of the medulla oblongata and wearing a dental prosthesis (area under the receiver-operator curve (AUC) of 76%). BP was significantly associated with NIHSS scores >4, male sex, bilateral cerebral lesions, the presence of SD, and the use of an enteral feeding tube (AUC 84%). In unadjusted analysis, unfavorable 12-month outcome and mortality were increased in the presence of SD. CONCLUSION: In AIS, SD and BP are associated with stroke severity and localization and wearing a dental prosthesis increases the risk of SD. Given that patients with SD have an increased risk of poor outcome and mortality, high-risk patients warrant early interventions, including more randomized trials.

Longitudinal study on risk indicators for peri-implantitis using survival-time analysis.

PURPOSE: The purpose of this study was to evaluate the incidence of peri-implantitis and to identify potential associated risk indicators. METHODS: This longitudinal study included 477 patients treated with 1420 implants. Medical and dental histories were evaluated in all patients. The location, size, connection type, surgical protocol, use of prosthesis splinting and fixation type were evaluated for each implant. In peri-implant evaluation, minimum keratinized tissue width around implants, peri-implant probing depths, peri-implant bleeding and peri-implant suppuration were assessed. Bone resorption around implants was evaluated with intraoral radiographs at baseline and at follow-up examinations. The study endpoint was peri-implantitis, which was defined as the presence of bleeding on probing and/or suppuration with bone resorption >1mm, in accordance with previous studies. Data were analyzed with mixed-effects Cox models. RESULTS: Peri-implantitis occurred in 15.3% of patients and 9.2% of implants. The overall 5- and 10-year cumulative implant survival rates were 0.95 (95% confidence interval [CI]: 0.93-0.96) and 0.83 (95% CI: 0.8-0.87), respectively. Age (hazard ratio [HR]=0.94, 95% CI: 0.90-0.98, p<0.01), plaque control record >20% (HR=2.61, 95% CI: 1.02-6.67, p=0.04), maxillary placement (HR=1.90, 95% CI: 1.11-3.23, p=0.02) and number of occlusal supports (HR=0.87, 95% CI: 0.77-0.99, p=0.03) were significantly correlated with peri-implantitis development. CONCLUSIONS: Within the limitations of this longitudinal study on risk indicators for peri-implantitis, age, inadequate plaque control, insertion in the maxilla and less occlusal support of natural teeth correlated with peri-implantitis development.
