The influence of active reminders on oral hygiene compliance in orthodontic patients

Eppright, Matthew 22 April 2013 (has links)
Text message reminders have proven effective for positive behavioral changes in medicine, but their influence on oral hygiene compliance has never been tested. This study aimed to determine if text message reminders about oral hygiene have an influence on the level of compliance. In this prospective randomized controlled clinical trial, 42 orthodontic patients were assigned to a text message or control group. Parents of patients assigned to the text message group received a reminder text message one weekday each week. Oral hygiene compliance was measured using bleeding index, modified gingival index, plaque index, and visual examination of white spot lesion development at baseline (T0), two appointments after baseline (T1), and four appointments after baseline (T2). Bleeding index, modified gingival index, and plaque index scores were significantly lower in the text message group than the control group at T2. A text message reminder system is effective for improving oral hygiene compliance in orthodontic patients.

The Anti-Plaque Efficacy of Listerine® Used in Combination with Toothbrushing in Orthodontic Patients

Casagrande, Zachary A. 01 January 2006 (has links)
The bactericidal efficacy of Listerine®, the essential oil-containing mouthrinse, has long been recognized. The purpose of this study was to determine whether Listerine® mouthrinse, when added to the standard oral hygiene regimen, had an added benefit in reducing plaque and gingivitis development in orthodontic patients over a six-month period. 50 orthodontic patients from the Virginia Commonwealth University Department of Orthodontics were assigned either to the brushing + flossing (N= 25) or brushing + flossing + Listerine® (N = 25) group. At baseline (TI), measurements for the Ramfjord teeth were recorded for the gingival index, plaque index and bleeding index. Subsequent measurements were taken at 3 and 6 months (T2 and T3, respectively). The response profiles for the BI, MGI, and PI over time were significantly different (p<.001) between the two groups. Patients who had Listerine&174; mouthrinse added to their daily oral hygiene regimen exhibited significantly lower BI, MGI, and PI scores at 3 months and 6 months than the patients who only brushed and flossed.

Associação entre higiene oral e os cânceres de cabeça e pescoço / Association between oral hygiene and head and neck cancer

Pereira, Nayara Fernanda 20 February 2018 (has links)
Introdução: Com as demonstrações da relação entre inflamação, desregulação microbiológica e câncer, a higiene oral precária pode ser um fator risco. Objetivo: Verificar se a condição de higiene está associada com a ocorrência dos cânceres de cabeça e pescoço. Material e método: Foram analisadas variáveis de condição de higiene bucal, como frequência de escovação, dentes perdidos, necessidade e uso de prótese e visita regular ao dentista num estudo caso-controle, com pacientes de cinco hospitais do estado de São Paulo, pareados por sexo e idade, do projeto multicêntrico ,,Genoma do Câncer de Cabeça e Pescoço\" (GENCAPO). Resultados: As neoplasias malignas mais frequentes foram as de bordo de língua (11,41%) e base de língua (10,92%). A análise estatística bivariada encontrou valores de Odds ratio abaixo de 1 para as variáveis: ,,escova 1x\" (OR=0,33; IC0,25-0,44), ,,escova 2x\" (OR=0,42;IC0,35-0,52), ,,usa fio sempre\" (OR=0,19;IC0,13-0,27), ,,usa fio às vezes\" (OR=0,19;IC0,15-0,24), ,,dentista todo ano\" (OR=0,29;IC0,22-0,37), ,,higiene boa\" (OR=0,21;IC0,166-0,27) e ,,higiene regular\" (OR=0,19;IC0,16-0,25) e acima de 1 para ,,sangra sempre\" (OR=2,40;IC1,40-4,09), ,,usa total\" (OR=1,99;IC1,54-2,56), ,,6 ou mais dentes perdidos\" (OR=3,30;IC2,67-4,08). A regressão logística multivariada encontrou significância para ,,escovar os dentes pelo menos 2x ao dia\" (OR=0,53;IC0,37-0,75), ,,fio sempre\" (OR=0,16;IC0,80-0,33) e para variável ,,6 ou mais dentes perdidos\" (OR=3,86;IC2,67-5,57). Discussão: Os dados mostram a necessidade de cuidados orais e indicam que higiene precária pode ser um fator de risco. Conclusão: Bons hábitos de higiene bucal possuem relação inversa com ocorrência de câncer em cabeça e pescoço e esses pacientes tem mais comorbidades bucais. / Introduction: As demonstrations of the relationship between inflammation, microbiological dysregulation and cancer, poor oral hygiene can be adapted for cancers. Objective: To verify if the hygiene condition is associated with the occurrence of head and neck cancers. Material and method: The variables of oral hygiene condition, such as toothbrushing frequency, missing teeth, need and use of prosthesis and regular visit to the dentist in a case-control study were analyzed with patients from five hospitals in the state of São Paulo, paired by sex and age, of the multicenter project ,,Genoma do Câncer de Cabeça e Pescoço\" (GENCAPO). Results: The most frequent malignancies were those of the tongue border (11.41%) and tongue base (10.92%). The bivariate statistical analysis found odds ratio values below 1 for the variables\' 1x brush \'(OR = 0.33; IC0.253-0.44),\' 2x brush \'(OR = 0.42; IC0.34-0.52),\' floss (OR = 0.19, IC0.13-0.27), \'sometimes uses floss\' (OR = 0.19, IC0.15-0.24), \'dentist every year\' (OR = 0.29, IC0.22-0.37), (OR = 0.21, IC0.167-0.27) and \'regular hygiene\' (OR = 0.19, IC0.156-0.25) and above 1 for \'always bleeds\' (OR = 2.40, CI 1.40-4.09), \'total use\' (OR = 1,99, IC1,54-2,56), \'6 or more missing teeth\' (OR = 3,30, IC2,67-4,08). Multivariate logistic regression found significance for \'brushing the teeth at least 2x a day\' (OR = 0.53, IC0.37-0.75), \'always wire\' (OR = 0.16, IC0.80-0.32) and for variable \'6 or more lost teeth \'(OR = 3.86, IC2.67-5.57). Discussion: Data show the need for oral care and indicate that poor hygiene may be a risk factor. Conclusion: Good habits of oral hygiene have an inverse relation with the occurrence of head and neck cancer and these patients have more oral comorbidities.

Uso de enxaguatórios bucais em pacientes portadores de câncer de boca e orofaringe / Mouthrinse use in patients with oral and oropharyngeal cancer

José Narciso Rosa Assunção Junior 06 August 2014 (has links)
O câncer de boca é atualmente um grave problema de saúde mundial. A incidência varia amplamente todo o mundo. Vários fatores de risco têm sido associados com cânceres da cavidade oral, tais como o fumo, consumo de bebidas alcoólicas, pobre saúde bucal e infecção pelo papiloma vírus humano. O mecanismo pelo qual bebidas alcoólicas provocam câncer oral é desconhecido, mas provavelmente envolve exposição tópica. Diferentes estudos têm sido conduzidos por muitos anos, a fim de esclarecer a possível relação entre o uso crônico de enxaguatórios bucais com álcool e câncer oral. O objetivo desse estudo foi avaliar o uso de enxaguatórios bucais em pacientes com câncer de boca e orofaringe. Foram entrevistados 53 pacientes por meio de um questionário específico de dois centros de referência para o diagnóstico e tratamento do câncer. O grupo caso foi constituído por 33 pacientes, com diagnóstico final de carcinoma epidermóide de boca e orofaringe com sítios nas seguintes localizações anatômicas: face interna dos lábios, língua, gengiva, assoalho da boca, palato e úvula, mucosa oral, vestíbulo da boca, área retromolar, outras partes e partes não especificadas da boca, amígdala e orofaringe. O grupo controle foi constituído por 20 pacientes atendidos em outros ambulatórios dos mesmos hospitais e serviços não ligados a oncologia. Os resultados obtidos mostraram que 42,4% dos pacientes do grupo caso eram portadores de lesão na língua e 16 casos (30,3%) estavam classificados como Estádio clínico IV. O uso de prótese não mostrou associação com relação aos grupos (p>0,05). No grupo caso, 81,8% não fazem uso de fio dental e com diferença estatisticamente significativa ao grupo controle (p=0,036). Quanto à escovação dentaria, notamos comportamento contrário onde os casos escovam mais vezes no dia do que o controles. Com relação ao enxaguante bucal, o grupo controle fazia menos uso de enxaguatórios quando comparado ao grupo caso que utilizava mais vezes ao dia (p=0,028). Os pacientes do grupo caso fumavam mais que os do grupo controle, sendo tal diferença significativa (p=0,004), quando se quantificou o consumo de tabaco em maços/ano (quantidade de maços de cigarro e equivalente em outros tipos de cigarro consumidos diariamente por 1 ano) tal diferença também se mostrou maior no grupo caso (p=0,044). O mesmo comportamento foi observado no consumo de etanol (consumo em mililitros por dia durante o ano) (p=0,031). Concluímos com este estudo que, mesmo com uma pequena casuística, através de uma analise estratificada, o uso de enxaguatório foi quatro vezes maior em etilistas, porém não se observou aumento do risco em tabagistas, abstêmios alcoólicos e não tabagistas. / Oral cancer is a major problem worldwide nowadays. The incidence varies widely throughout the world. A great variety of risks have been associated with oral and oropharyngeal cancers,such as tobacco and alcohol consumption, poor oral health, and human papilloma virus infection. The mechanism through which alcohol contributes to oral cancer is unknown, but it probably involves topical and systemic exposition. Different studies aiming to clarify a possible association between alcoholic mouthwashes and oral cancer have been conducted for many years. The objective of this study was to evaluate oral hygiene habits and the use of mouthwashes in oral and oropharyngeal cancer patients. Fifty-three patients from two cancer centers were interviewed by means of a specific questionnaire. The case group comprised 33 patients diagnosed with squamous cell carcinoma located at the following anatomical sites: lips, tongue, gingiva, floor of the mouth, buccal mucosa, palate, uvula, pharyngeal tonsil, oropharynx, and other non-specified parts. The control group comprised 20 patients with non-neoplastic treatments. The results showed that 42.4% the of case group patients presented tongue lesions, 16 patients were classified at stageIV. The dental prosthesis used were not associated with either group (p>0.05). In the case group,81.8% of the patients do not use dental floss, with statistical significance forthe control group (p=0.036). Tooth brushing was more frequent in the case group compared with the control group. Oral mouthwash use was less common in the control group thanin the case group (p=0.028). Tobacco was widely used in the case group, with statistical significance (p=0.004); when the amount of tobacco in packs/yearwas quantified, the difference was higher in the case group (p=0.0044). The same pattern was observed for alcohol consumption (ml-day/year) (p=0.031). Despite the minor casuistic, using a stratified analysis, we conclude that the use of oral mouthwash was four times higher in alcoholic patients, but no increasedrisk was observed in tobacco users, alcohol abstainers, and non-smokers.

Oral hygiene in the control of occlusal caries in newly erupted first permanent molars.

Arrow, Peter G. January 1997 (has links)
Caries of the pits and fissures of permanent teeth continues to be a problem for children. Newly erupted permanent molars are particularly at risk. Oral hygiene measures have been shown to be able to reduce the incidence of caries. The aim of this study was to compare the caries preventive effects of a professional tooth cleaning and oral health education programme (test) with a standard preventive programme (comparison), comprising selective fissure sealing and application of topical fluorides on newly erupted first permanent molars. School Dental Service clinics of the Health Department of Western Australia, in Perth, were assigned to test (4)or comparison (4) clinics. Schoolchildren, mean age 6.3 plus or minus 0.3 (s) yr with, sound, newly erupted first permanent molars were included in the study (n=404; 207 test; 197 control).Children were examined after twelve and twenty-four months by an examiner who was 'blind' to the test or control status of the children. After twelve months, 186 test and 163 control children were examined, and after twenty-four months, 179 test and 156 control children were examined. Three hundred and twenty children were examined in both years. After twenty-four months, 32 children in test and 31 children in control developed caries of the first permanent molars, the estimated risk ratio was 0.90 (95% CI 0.58, 1.41); and children in the test group had an average DFT score of 0.30 plus or minus 0.75 compared with 0.30 plus or minus 0.70 DFT in the control group (t-test, p=0.96). The results suggest that, after two years, there was no statistically significant difference between the caries preventive effects of a professional tooth cleaning and oral health education programme and a programme based on selective fissure sealing and application of topical fluorides.Baseline deciduous caries experience, presence of hypomineralised first ++ / permanent molars and frequency of toothbrushing were statistically significant factors in predicting molar caries. Using baseline deciduous caries experience as a screening criterion to predict permanent molar caries, sensitivity of 0.67 and specificity 0.61 were obtained at a cutpoint of 1 dmfs. Sensitivity and specificity values were maximised at 0.72 by using a combined baseline dmfs and hypomineralisation as screening criteria. Cost-effectiveness analysis indicated an incremental cost-effectiveness ratio of $40/child/year. The test programme was more costly and produced similar outcomes and does not warrant adoption on economic grounds.

Patientens kunskap om parodontit före och efter icke kirurgisk parodontal behandling utförd av tandhygienist : En kvantitativ studie

Yousef Amed, Jwan, Ahmad, Trifa January 2010 (has links)
Parodontit är en kronisk inflammatorisk sjukdom, som orsakas av patogena bakterier som fäster på tändernas ytor, där de bildar plack. Sjukdomen kan förebyggas genom god munhygien. Syftet med studien var att beskriva och jämföra parodontit relateradkunskap och dess relation till munhygiensvanor hos patienter före och 1-år efter icke kirurgisk parodontal behandling utförd av tandhygienist samt jämföra om det föreligger någon skillnad i kunskap efter behandling mellan två olika munhälsoundervisningsprogram. Ett ytterligare syfte var att beskriva om det föreligger någon skillnad i kunskap om parodontit med avseende på ålder, kön och utbildningsnivå. Studien var en beskrivande, jämförande studie med kvantitativ ansats och en del av en experimentell tvågruppsstudie.Urvalet bestod av 113 individer, 60 kvinnor och 53 män, i åldern 20-65 år som var remitteras till en specialistklinik i parodontologi. Av de 113 studiedeltagarna randomiserades 57 personer till ett individuell skräddarsydd munhälsoundervisningsprogram och 56 personer till ett standardiserat munhälsoundervisningsprogram. Ett frågeformulär med 11 påståenden gällande kunskap om parodontit och ett påstående om tandborstfrekvens samt ett påstående om approximalrengörning användes.Resultatet visade att patienterna hade mer kunskap efter icke kirurgisk parodontal behandling, men det fanns ingen skillnad mellan undervisningsprogrammen. Inget samband påvisades mellan kunskap om parodontit och utbildningsnivå, kön och ålder. Studien visar att både individuellt skräddarsydd munhälsoundervisning och standard munhälsoundervisning ledar till en ökad kunskap om parodontit mellan deltagarna.

Comparison of an essential oil mouth rinse and chlorhexidine on 4-day interproximal plaque regrowth.

Jarrar, Ahmed Ali. January 2006 (has links)
<p>Dental plaque is the most important etiological factor of periodontal diseases. Mechanical plaque control is the most effective way in preventing periodontal diseases. Chemical plaque control methods (such as mouthrinses) have been recommended to be used because of some drawbacks in the mechanical methods in some areas of the dentition (such as interproximal areas). But are these mouthrinses really effective in those areas? The aim of this study was to compare the effectiveness of Essential Oils mouthrinse (Listerine) on plaque formation in interproximal areas with Chlorhexidine and Sterile water.</p>
