Randomized trial of dentists' understanding: treatment benefit in absolute numbers vs relative risk reduction.

This study aimed to assess whether dentists correctly understand the benefit of a dental treatment when it is presented using absolute numbers or relative risk reduction (RRR). This parallel-group randomized controlled trial recruited dentists from 3 postgraduate courses in Rio de Janeiro, Brazil. Participants received, in sequentially numbered sealed opaque envelopes, the description of a hypothetical scenario of the benefit (avoidance of multiple tooth loss) of nonsurgical periodontal treatment without or with antibiotics. Treatment benefit was presented in 2 different formats: absolute numbers or RRR. Dentists were given 10 minutes to read the treatment scenario and answer 5 questions. The final sample for analysis included 101 dentists. When asked to estimate the number of patients out of 100 who would avoid multiple tooth loss without antibiotics, 17 dentists (33%) in the absolute numbers group and 12 (25%) in the RRR group provided the correct response (p = 0.39). Regarding treatment with antibiotics, 26 dentists (50%) in the absolute numbers group and 14 (29%) in the RRR group provided the correct response (p = 0.04). Only 16 dentists (31%) in the absolute numbers group and 12 (25%) in the RRR group gave correct answers for both questions (p = 0.51). Most dentists did not correctly understand the benefit of the treatment, irrespective of the format it was presented. Slightly more dentists correctly understood the benefit of the treatment when it was presented as absolute numbers than as RRR.

Análise comparativa das queixas disfágicas em idosos diabéticos e não diabéticos / Comparative analysis of dysphagic complaints in diabetic andnon-diabetic elderly

Distúrbios no processo de deglutição podem ocorrer em qualquer idade, no entanto o risco de disfagia aumenta com a idade avançada. Alterações na função de deglutição causadas pelo envelhecimento são denominadas presbifagia. A frequência da disfagia na população idosa é visivelmente alta. Cerca de 40% dos indivíduos com mais de 60 anos apresentam alguma queixa de disfagia. Apesar da alta prevalência entre idosos a disfagia é subdiagnosticada. Quanto maior o tempo de diagnóstico de Diabetes Mellitus (DM) em anos, maiores podem ser os sintomas de disfagia, devido às complicações micro e macro vasculares que o DM pode provocar. Objetiva Analisar as queixas disfágicas em idosos diabéticos e não diabéticos, usando o protocolo de rastreio RaDI-H. Metodologia: Trata-se de um estudo descritivo, transversal, quantitativo de corte analítico, desenvolvido em usuários internados no Hospital Estadual Alberto Rassi-HGG, com a aplicação do protocolo autorreferido RaDI-H. Neste estudo não foram encontradas associações significativas ao analisar as queixas disfágicas em idosos diabéticos e não diabéticos. O protocolo de rastreio de disfagia RaDI-H mostrou que a maioria dos participantes obteve pontuação negativa (98,04%) o que evidencia, possivelmente, baixa sensibilidade do instrumento para idosos diabéticos, sem alterações neurológicas. Este estudo não apontou correlações significativas nas queixas disfágicas em idosos e diabéticos e não diabéticos, usando o protocolo de rastreio RaDI-H, entretanto observou-se que os usuários fazem adaptações nas consistências da alimentação, devido às alterações estruturais e funcionais do sistema estomatognático advindas do processo natural do envelhecimento

Disorders in the swallowing process can occur at any age, however the risk of dysphagia increases with advanced age. Changes in swallowing function caused by aging are called presbyphagia. The frequency of dysphagia in the elderly population is visibly high. About 40% of individuals over 60 years of age have some complaint of dysphagia. Despite the high prevalence among the elderly, dysphagia is under diagnosed. The longer the time of Diabetes Mellitus (DM) diagnosis in years, the greater the dysphagia symptoms due to the micro and macrovascular complications that DM can cause. To analyze dysphagic complaints in diabetic and non-diabetic elderly using the RaDI-H screening protocol. This is a descriptive, cross-sectional, quantitative analytical study developed with users hospitalized at the Hospital Estadual Alberto Rassi - HGG. With the application of the self-reported RaDI-H protocol. In this study, no significant associations were found when analyzing dysphagic complaints in diabetic and non-diabetic elderly. The RaDI-H dysphagia screening protocol showed that most participants obtained a negative score (98.04%), which possibly shows the instrument's low sensitivity for diabetic elderly people without neurological disorders. This study did not indicate significant correlations in dysphagic complaints in the elderly and diabetics and non-diabetics. However, through the RaDI-H screening protocol, it was observed that users make adjustments in food consistencies due to structural and functional changes in the stomatognathic system arising from the natural aging process

The loss of molars in supportive periodontal care: A 10-year follow-up for tooth- and patient-related factors.

AIM: To determine the impact of the degree of furcation involvement (FI) on the longevity of molar teeth and assess the risk variables (tooth- and patient-related factors) associated with the loss of molars (LM) in individuals treated for periodontitis and monitored in a private programme of supportive periodontal care (SPC). MATERIALS AND METHODS: The present retrospective cohort study included 222 individuals with 1329 molars under a 10-year monitoring period in SPC. Periodontal clinical parameters, FI, the type of molar, pulp vitality, and other variables of interest were collected at approximately 50 days after active periodontal therapy and after 10 years. The association of tooth- and patient-related factors with LM was assessed using a multilevel Cox regression analysis. RESULTS: Two-hundred and thirty-five molars were extracted during the SPC period of 12.4 ± 1.9 years. Age >50 years, male gender, diabetes, smoking, and non-compliance were identified as relevant patient-related factors for LM during SPC (p < .05). Significant tooth-related factors for LM were bleeding on probing (BoP) and probing depth (PD) ≥5 mm, tooth non-vitality, and class II and III FI (p < .05). CONCLUSIONS: Class III FI, tooth non-vitality, higher mean PD and BoP, age, male gender, diabetes, and smoking all strongly influenced the prognosis of molars during SPC.

Smoking Cessation therapy is a cost-effective intervention to avoid tooth loss in Brazilian subjects with periodontitis: an economic evaluation.

BACKGROUND: Smokers present a higher prevalence and severity of periodontitis and, consequently, higher prevalence of tooth loss. Smoking cessation improves the response to periodontal treatment and reduces tooth loss. So, the aim of this study was to evaluate the efficiency in resources allocation when implementing smoking cessation therapy vs. its non-implementation in smokers with periodontitis. METHODS: We adopted the Brazilian public system perspective to determine the incremental cost-effectiveness (cost per tooth loss avoided) and cost-utility (cost per oral-related quality-adjusted life-year ([QALY] gained) of implementing smoking cessation therapy. Base-case was defined as a 48 years-old male subject and horizon of 30 years. Effects and costs were combined in a decision analytic modeling framework to permit a quantitative approach aiming to estimate the value of the consequences of smoking cessation therapy adjusted for their probability of occurrence. Markov models were carried over annual cycles. Sensitivity analysis tested methodological assumptions. RESULTS: Implementing the therapy saved approximately US$ 100 over the time horizon accompanied by a slightly better effect, both in CEA and CUA. Considering uncertainties, the therapy could be cost-effective in the most part of simulated cases, even being cheaper and more effective in 35% of cases in which the oral-health related outcome is used as effect. Considering a willingness-to-pay of US$100 per health effect, smoking cessation therapy was cost-effective, respectively, in 72% and 99% of cases in cost-utility and cost-effectiveness analyses. CONCLUSIONS: Implementation of smoking cessation therapy may be cost-effective, considering the avoidance of tooth loss and oral health-related consequences to patients.

Restauración post-endodoncia y condición social como factor de preservación dentaria: parte 1 / Post-endodontic restoration and social condition as afactor of tooth preservation. part 1

El objetivo de este estudio fue conocer el estado dental de piezas endodonciadas en correlación conlas variables de restauración coronaria, nivel de estudio, condición laboral y acceso a servicios odontológicos. Para ello, se analizó una población de individuos, compuesta por sujetos concurrentes a los cursos de posgrado de Endodoncia del Círculo Odontológico de Córdoba y al servicio de la Cátedra“B” de Endodoncia de la Facultad de Odontología de la Universidad Nacional de Córdoba. Se hicieron tratamientos controlados durante dieciocho meses. La muestra total la conformaron 144 pacientes y se trataron 174 casos. Sólo asistieron a control el 48,6 por ciento de los pacientes, de los cuales se evaluaron 89 dientes. El estudio mostró 37 casos con restauración coronaria definitiva sin fracturas, 52 dientes sinrestauración, 21 con fracturas y 1 se perdió. Se observó un incremento de fracturas en control a los 18 meses. La tasa de fracturas evidenció un mayor porcentaje en pacientes con nivel de estudio alto, menor en pacientes sin trabajo, y mayor en pacientes con trabajo estable y precario. El tipo de atención no se diferenció, pero los porcentajes observados sugieren que los atendidos en asistencia pública tendrían más probabilidad de fracturas. Se observó un mayor porcentaje de restauraciones definitivas enatención privada y menor en consultorios públicos. El elevado porcentaje de inasistencia a controlesmotivó un análisis específico, del cual se pudo concluir que a mayor estabilidad laboral, de estudios yde asistencia privada, mayor fue la asistencia a controles. Estos datos revelan información importantepara establecer políticas públicas de la atención posendodoncia.

The aim of this study was to know the dental state of endodontic pieces in correlation with different variables such as coronary restoration, level of study, employment status and access to dental services.To do so, we analyzed a population composed of subjects who participated in two different graduate courses at the Círculo Odontológico de Córdoba and the “Chair B” of Endodontics of the Faculty ofDentistry, National University of Córdoba. Treatments were clinically and radiographically controlled for eighteen months. The total sample included 144 patients and 174 treatments. Only 48.6% patients attended the control, 89 teeth of whom were evaluated. The study showed 37 cases with definitivecoronary restoration without fractures, 52 teeth without restoration, 21 with fractures, and 1 was lost.The fracture rate showed an increase in patients with high level of study, a decrease in unemployed patients, and an increase in both patients with stable and precarious work. The kind of attention didnot differ, but the observed percentages suggest that patients treated in public services would be morelikely to suffer from fractures. There was a higher percentage of definitive restorations in private services,and lower in public ones. The high percentage of non-attendance to controls motivated a specific analysis, from which it is possible to conclude that the more job stability, studies and private access todental services, the more the attendance to controls. These data reveal important evidence in order to establish public policies of post-endodontic services.

Restauración post-endodoncia y condición social como factor de preservación dentaria: parte 2 / Post-endodontic restoration and social condition asa factor of tooth preservation. Part 2

El objetivo de este estudio fue conocer el estado dental de piezas endodonciadas en correlación conlas variables de restauración coronaria, estado periodontal, nivel de estudio, condición laboral y acceso a servicios odontológicos. Para ello, se analizó una población de individuos compuesta por sujetos concurrentes a los cursos de posgrado de Endodoncia, del Círculo Odontológico de Córdoba, y al servicio de la Cátedra “B” de Endodoncia de la Facultad de Odontología, Universidad Nacional de Córdoba. Se hicieron tratamientos controlados durante dieciocho meses. La muestra total la conformaron 144 pacientes y se trataron 174 casos. El estudio mostró 37 casos con restauración coronaria definitiva sin fracturas, 52 dientes sin restauración, 21 con fracturas y 1 se perdió. De los dientes restaurados, el55,6 por ciento mostraron periodonto normal; 22,2 por ciento gingivitis, y 22 por ciento periodontitis leve. De los dientes sin restauración, el 3,9 por ciento mostraron periodonto normal; 7,8 por ciento gingivitis; 31,4 por ciento periodontitis leve; 35,3 por ciento periodontitis grave y 21,6 por ciento periodontitis complicada. De los dientes fracturados, el 16,7 por ciento mostraron periodonto normal o gingivitis; 35,3 por ciento periodontitis leve y grave, y un 72,7 por ciento periodontitis complicada. No se demostró asociación entre nivel de estudios, condición laboral y tipo de atención con fracturas de los pacientes, pero los porcentajes sugieren más probabilidad de sufrir fractura en los pacientes de la asistencia pública. El elevado porcentaje de inasistencia a control motivó un análisis específico, del cual se pudo concluir que cuanto más grave la patología periodontal, mayor el porcentaje de inasistencia. El estudio permitió observar desigualdad en el acceso a los servicios odontológicos, dientes no rehabilitados y con compromiso periodontal.

The aim of this study was to know the dental state of endodontic pieces in correlation with different variables such as coronary restoration, periodontic condition, level of study, employment status and access to dental services. A population composed of patients treated in two different postgraduate courses at the Círculo Odontológico de Córdoba and Chair “B” of Endodontics, Faculty of Dentistry,National University of Córdoba were analyzed. Treatments were clinically and radiographicallycontrolled for eighteen months. The total sample included 144 patients and 174 treatments. The studyshowed 37 cases with definitive coronary restoration without fractures, 52 teeth without restoration,21 with fractures, and 1 was lost. From restored teeth, 55.6% showed normal periodontium, 22.2%gingivitis, and 22% mild periodontitis. From teeth without restoration, 3.9% showed normalperiodontitis, 7.8% gingivitis, 31.4% mild periodontitis, 35.3% severe periodontitis and 21.6%complicated periodontitis. From fractured teeth, 16.7% showed normal periodontitis or gingivitis, 35.3% had mild and severe periodontitis, and 72.7% had complicated periodontitis. There has beenno correlation between level of education, work status, and kind of service on patient with fractures,but the percentage suggest that patients in public assistance are more likely to suffer fracture. The highpercentage of non-attendance to control led to a specific analysis, from which it is possible to concludedthat the more severe the periodontal disease, the greater the percentage of non-attendance. The study showed inequality in access to dental services, un rehabilitated teeth and with periodontal compromise.

Terapia de manutenção periodontal: perfil microbiológico e efeito do tabagismo na perda dental / Periodontal maintenance therapy: microbial profile and effects of smoking on tooth loss

Esta Tese reporta dois estudos distintos relacionados à terapia de manutenção periodontal (TMP): achados microbiológicos longitudinais de 6 anos relacionados à cooperação dos indivíduos e efeito do tabagismo na perda dental. A justificativa para estes estudos é baseada em dois aspectos pontuais: (1) Embora a associação do tabagismo como fator de risco para a periodontite e pior resposta à TMP tenha sido demonstrada em muitos estudos, o efeito isolado deste sobre a perda dental em indivíduos submetidos a TMP ainda não foi reportado em revisões sistemáticas; (2) Poucos estudos têm sido conduzidos avaliando mudanças longitudinais na microbiota subgengival de indivíduos em TMP e, até o momento, nenhum estudo relacionou níveis de bactérias associadas à periodontite com o grau de cooperação dos indivíduos em TMP. Neste sentido, os objetivos deste estudo são apresentados em dois artigos científicos: (1) realizar uma revisão sistemática e meta-análise do efeito do tabagismo na perda dental em indivíduos em TMP, com a seguinte questão focal: ¿Qual é o efeito do tabagismo na perda dental em indivíduos em terapia de manutenção periodontal?¿; (2) avaliar longitudinalmente, durante 6 anos, o efeito da cooperação em TMP na frequência das bactérias Actinomyces naeslundii, Porphyromonas gingivalis, Tanerella forsythia e Treponema dentícola. Na revisão sistemática as bases de dados MEDLINE, WEB OF SCIENCE, COCHRANE LIBRARY e SCOPUS foram pesquisadas, incluindo artigos até fevereiro de 2017. A estratégia de busca identificou 728 referências. Após a remoção das duplicatas, restaram 591 para a seleção baseada nos títulos e resumos, e desses, foram selecionados 36 para leitura completa do texto. Após a leitura, foram incluídos 10 artigos para revisão sistemática e 3 artigos para meta-análise. A qualidade da evidência científica foi moderada para indivíduos tabagistas em TMP apresentarem maior chance de perda dental que indivíduos não tabagistas. A metodologia do estudo microbiológico englobou um total de 56 indivíduos, todos recrutados de um coorte prospectivo com 212 participantes de um programa de TMP. Estes indivíduos foram acompanhados durante 6 anos, em 5 tempos de avaliações: T1 (anterior à terapia periodontal ativa), T2 (após a terapia periodontal ativa), T3 (última visita à TMP em 2 anos), T4 (última visita à TMP em 4 anos) e T5 (última visita à TMP em 6 anos). Assim, 28 indivíduos cooperadores regulares (CR) foram randomizados e pareados, pelo gênero e idade, a 28 indivíduos cooperadores irregulares (CI). Durante a TMP, os exames periodontais avaliaram os parâmetros clínicos: índice de placa (IP), profundidade de sondagem (PS), nível clínico de inserção (NCI) e sangramento à sondagem (SS). A quantificação de bactérias em carga total e dos níveis de A. naeslundii, P. gingivalis, T. forsythia e T. dentícola foi executada pela reação em cadeia da polimerase quantitativa (qPCR). Este estudo concluiu que CI apresentaram piores parâmetros clínicos periodontais e maiores níveis de carga bacteriana total que CR, refletindo o papel benéfico da cooperação na TMP em manter a estabilidade da condição periodontal

This Thesis report two distinct issues related to periodontal maintenance therapy (PMT): microbiological findings of 6 years related to compliance of individuas and effect of smoking on tooth loss. The rattionale for these studies is based on two specific aspects: (1) Although the association of smoking as a risk factor for periodontitis and worse response to PMT has been demonstrated in many studies, the isolated effect of smoking on tooth loss in patients undergiong PMT has not been reported in systematic reviews; (2) Few studies have been conducted on longitudinal changes in the subgingival microbiota of individuals in PMT and to date, no study related levels of bacteria to the degree of cooperation of individuls in PMT...

Change in Quality of Life and Its Association with Oral Health and Other Factors in Community-Dwelling Elderly Adults-A Prospective Cohort Study.

OBJECTIVES: To determine whether changes in oral health status were associated with decline in quality of life (QoL). DESIGN: Prospective cohort study. SETTING: Carlos Barbosa, southern Brazil. PARTICIPANTS: A random sample of 872 community-dwelling individuals aged 60 and older was evaluated in 2004. The current study population consisted of 389 participants available for follow-up in 2012. MEASURES: Change in QoL was assessed through the use of the short version of the World Health Organization QoL Assessment tool (WHOQOL-BREF) at baseline and follow-up. Each WHOQOL domain generates a score, with changes being calculated for each domain. Individuals with the same or higher scores at follow-up were categorized as having improved QoL, and those with lower scores were categorized as having a decline in QoL. Sociodemographic and health variables were assessed in an interview, and tooth loss, use of dental prostheses, and satisfaction with chewing ability and oral appearance were verified through oral examinations. Interviews and examinations were repeated. Risk ratios (RRs) relative to the outcome and independent variables were estimated using Poisson regression with a robust variance estimator. RESULTS: Tooth loss was a risk factor for decline in the psychological domain of QoL (RR = 1.04, 95% confidence interval (CI) = 1.02-1.06). Improvement in satisfaction with chewing ability was a protective factor for decline in this same domain (RR = 0.69, 95% CI = 0.50-0.97). Greater satisfaction with oral appearance was a protective factor against decline in social (RR = 0.84, 95% CI = 0.72-0.98) and environmental (RR = 0.77, 95% CI = 0.61-0.97) domain scores. CONCLUSION: Preventing tooth loss and recognizing and properly addressing concerns about chewing and dental appearance can affect the general well-being of community-dwelling elderly adults.

Relationship between premature loss of primary teeth with oral hygiene, consumption of soft drinks, dental care, and previous caries experience.

We determine the relationship between premature loss of primary teeth and oral hygiene, consumption of soft drinks, dental care and previous caries experience. This study focused on 833 Mexican schoolchildren aged 6-7. We performed an oral examination to determine caries experience and the simplified oral hygiene index. The dependent variable was the prevalence of at least one missing tooth (or indicated for extraction) of the primary dentition; this variable was coded as 0 = no loss of teeth and 1 = at least one lost primary tooth. The prevalence of at least one missing tooth was 24.7% (n = 206) (95% CI = 21.8-27.7). The variables that were associated with the prevalence of tooth loss (p < 0.05) included: the largest number of decayed teeth (OR = 1.11), the largest number of filled teeth (OR = 1.23), the worst oral hygiene (OR = 3.24), a lower frequency of brushing (OR = 1.60), an increased consumption of soda (OR = 1.89) and use of dental care (curative: OR = 2.83, preventive: OR = 1.93). This study suggests that the premature loss of teeth in the primary dentition is associated with oral hygiene, consumption of soft drinks, dental care and previous caries experience in Mexican schoolchildren. These data provide relevant information for the design of preventive dentistry programs.

Importancia del primer molar permanente y consecuencias clínicas de su pérdida en edades tempranas del desarrollo / Importance of the first permanent molar and clinical consequences of its loss at early developmental stages

El primer molar permanente es la undiad más importante de la masticación y es esencial en el desarrollo de una oclusión funcionalmente deseable. La pérdida de este molar en un niño puede conducir a cambios en las arcadas dentarias que se perpetúan a lo largo del tiempo. Si no se toman medidas preventivas o correctivas apropiadas, podrán encontrarse: disminución en la función local, desviaciones de las piezas dentarias, extrusión de la pieza antagonista y trastornos de las articulaciones temporomandibulares, entre otras alteraciones. El presente artículo pretende evidenciar el protagonismo del primer molar permanente en la cavidad bucal y las consecuencias negativas que derivan de su ausencia. Además, deja entrever las necesidades de conocimiento por parte del odontólogo en los cuidados preventivos de dichas piezas dentarias y sobre la existencia de posibles tratamientos al momento de una pérdida inminente.

Extreme root resorption associated with induced tooth movement: A protocol for clinical management

Cases in which teeth have only the cervical third remaining from orthodontically induced external root resorption, cast the following doubts: 1) What care should be taken to keep these teeth in mouth with the least risk possible? 2) What care should be taken with regards to reading of imaging exams, particularly in terms of accurately determining cervical root and bone loss? 3) Why is not endodontic treatment recommended in these cases? The present study aims at shedding light on the aforementioned topics so as to induce new insights into the theme.

Nos casos em que os dentes têm apenas o terço cervical remanescente de uma reabsorção radicular externa induzida ortodonticamente: 1) Quais seriam os cuidados para que permaneçam na boca, com o menor risco possível de perda? 2) Quais seriam os cuidados na interpretação imaginológica desses casos, quanto à determinação precisa da perda radicular e óssea cervical? 3) Por que o tratamento endodôntico não estaria indicado? No presente trabalho, procura-se esclarecer esses pontos e respondendo os questionamentos, para induzir novos insights sobre o assunto.

[Access to information on oral hygiene and tooth loss due to caries among adults]. / O acesso à informação sobre higiene bucal e as perdas dentárias por cárie entre adultos.

This study sought to establish the association between tooth loss due to dental caries and variables related to access to information on oral health in adults aged 35-44 years (n = 780) who participated in a large epidemiological study. The dependent variable was total tooth loss due to caries. The independent variables were grouped into blocks: demographic and socio-economic characteristics, use of dental service, access to oral health information (about how to prevent oral problems; oral hygiene; and diet), and behaviors. The analysis was conducted using hierarchical multiple linear regression. The mean number of lost teeth due to caries was 7.03. High numbers of lost teeth were higher among females and older adults; low levels of education; adults who rarely/never received oral hygiene information; those who brushed their teeth once a day or less; and those adults who did not use dental floss (p < 0.05). Adults who rarely/never received oral hygiene information from dental services lost 2.15 more teeth due to caries than those who always/often received such information (p = 0,000). Thus, it is suggested that access to information should be encouraged to contribute to greater equity in oral health.

O acesso a informacao sobre higiene bucal e as perdas dentarias por carie entre adultos / Access to information on oral hygiene and tooth loss due to caries among adults

Objetivou-se testar a associação entre perdas dentárias por cárie (PDC) e variáveis relativas ao acesso a informações em saúde bucal. Foram analisados dados de 780 adultos (35-44 anos) participantes de um estudo epidemiológico. A variável dependente foi o total de PDC e as independentes foram reunidas em blocos de variáveis: demográficas e socioeconômicas; utilização dos serviços odontológicos; acesso a informações em saúde bucal (informações sobre como evitar problemas bucais, sobre higiene bucal e sobre dieta) e; comportamentais. Conduziu-se regressão linear múltipla hierarquizada. O número médio de PDC foi de 7,03 (EP= 0,31) e 83% dos adultos haviam perdido algum dente por cárie. As PDC foram maiores entre os mais velhos, os com menor escolaridade, as mulheres, os que raramente ou nunca receberam informações sobre higiene bucal, os que escovavam os dentes uma vez ou menos ao dia e entre os que não usavam fio dental. Adultos que raramente/nunca receberam informações dos serviços odontológicos sobre higiene bucal perderam 2,15 dentes a mais por cárie que aqueles que sempre/frequentemente receberam tais informações (p = 0,000). Assim, sugere-se que a garantia do acesso à informação deva ser incentivada a fim de contribuir com maior equidade em saúde bucal. .

Incorporating severity and risk as factors to the Fardal cost-effectiveness model to create a cost-benefit model for periodontal treatment.

BACKGROUND: A previously described economic model was based on average values for patients diagnosed with chronic periodontitis (CP). However, tooth loss varies among treated patients and factors for tooth loss include CP severity and risk. The model was refined to incorporate CP severity and risk to determine the cost of treating a specific level of CP severity and risk that is associated with the benefit of tooth preservation. METHODS: A population that received and another that did not receive periodontal treatment were used to determine treatment costs and tooth loss. The number of teeth preserved was the difference of the number of teeth lost between the two populations. The cost of periodontal treatment was divided by the number of teeth preserved for combinations of CP severity and risk. RESULTS: The cost of periodontal treatment divided by the number of teeth preserved ranged from (US) $1,405 to $4,895 for high or moderate risk combined with any severity of CP and was more than $8,639 for low risk combined with mild CP. The cost of a three-unit bridge was $3,416, and the cost of a single-tooth replacement was $4,787. CONCLUSION: Periodontal treatment could be justified on the sole basis of tooth preservation when CP risk is moderate or high regardless of disease severity.

Qué medidas preventivas aplicamos en nuestra práctica diaria ante un paciente con riesgo de padecer enfermedad gingivo-periodontal? / What preventive measures do we apply in our daily practice for a patient at risk of gingivo-periodontal disease?

Las manifestaciones clínicas de la enfermedad periodontal son producto de una compleja interacción entre el agente causal (bacterias específicas de la placa dental) y los tejidos del huésped, en el particular ambiente de la interfaz diente-tejido. La periodontitis es una enfermedad infecciosa, originada por BACTERIAS, predominantemente Gram negativas, que son NECESARIAS para el desarrollo de la misma, pero NO suficientes, ya que requieren un HUESPED SUSCEPTIBLE.2 La susceptibilidad del huésped permite comprender las diferencias en el establecimiento, historia natural y la progresión de la periodontitis como también la respuesta al tratamiento.Un gran número de factores genéticos y/o adquiridos o ambientales ponen al huésped en RIESGO para la periodontitis, por eso hablamos de una etiología MULTIFACTORIAL para la misma, en la que se da la concurrencia simultánea de varios elementos que se modifican entre si a lo largo del tiempo.Page y Korman proponen un nuevo paradigma para la patogénesis de la periodontitis, basado en los avances en tres áreas especificas del conocimiento:1. Las bacterias son necesarias pero NO suficientes. 2. La flora bacteriana subgingival con características de BIOFILM. 3. Los avances a nivel celular, molecular y genético que permiten conocer a las bacterias presentes en el biofilm que INICIAN y PERPETUAN la respuesta inmunoinflamatoria.
