Purpose: This prospective clinical trial compared the retention rate and caries-preventive efficacy of two types of sealant modalities over a 3-year period. Materials and Methods: Using a split-mouth randomised design, 1280 sealants were randomly applied on sound permanent second molars of 320 young patients aged between 12 and 16 years. Half of the teeth (n = 640) were sealed with a resin-modified glass ionomer cement (RMGIC) (Vitremer (TM), 3M ESPE) and the other half (n = 640) with a conventional light-cure, resin-based fissure sealant (LCRB) (Fluoroshield (R), Dentsply Caulk). Teeth were evaluated at baseline, 6-, 12-, 18-, 24-, 30- and 36-month intervals with regard to retention and new caries development. Results: On the sealed occlusal surfaces after 3 years, 5.10% of RMGIC and 91.08% of LCRB sealants were totally intact and 6.37% of RMGIC and 7.65% of LCRB sealants were partially intact. New caries lesions were found in 20.06% of RMGIC sealed occlusal surfaces, compared to 8.91% for LCRB sealants. Conclusions: The findings of the present clinical study suggest that RMGIC should be used only as a transitional sealant that can be applied to newly erupting teeth throughout the eruptive process, whereas LCRB sealants are used to successfully prevent occlusal caries lesions once an effective rubber dam can be achieved. It can be concluded that there are differences between the RMGIC and LCRB sealants over a 3-year period in terms of the retention rate and caries-preventive efficacy. RMGIC can serve as a simple and economic sealing solution...

A xerostomia é um efeito adverso comum e frequentemente irreversível decorrente da radioterapia de neoplasias malignas da região de cabeça e pescoço, afetando, sobremaneira, a qualidade de vida dos pacientes. Diferentes métodos para solucionar tal problema são propostos, de resultados, todavia questionáveis. Este estudo avaliou a eficácia clínica da acupuntura como método de tratamento preventivo e curativo de tais condições. Os pacientes foram distribuídos, aleatoriamente, em três grupos: grupo preventivo, constituído de 12 indivíduos, sem queixa de secura bucal, tratados com 12 a 16 sessões de acupuntura, antes e durante a radioterapia; grupo curativo, constituído de 12 indivíduos, diagnosticados, clinicamente, com xerostomia severa, tratados com 12 aplicações de acupuntura após concluído o tratamento oncológico, e grupo controle, formado pelos mesmos indivíduos do grupo curativo no momento da primeira consulta, precedente à terapêutica com acupuntura. O tratamento foi conduzido de acordo com os princípios da medicina tradicional chinesa e medicina ocidental ortodoxa, realizado de forma padronizada para todos os pacientes, duas vezes por semana, por um período de 20 minutos cada sessão. A avaliação da eficácia terapêutica fundamentou-se na mensuração da xerostomia...

Com o objetivo de investigar o efeito do conhecimento e atitudes pessoais, hábitos de higiene oral e uso de fluoretos sobre a total ausência de cáries, realizou-se um estudo do tipo caso-controle entre estudantes universitários da região sul do Brasil. A análise bruta por regressão logística condicional não demonstrou efeito para as variáveis relacionadas ao uso de fluoretos e hábitos de higiene oral (p > 0,20). Já o uso de fio dental apareceu como um fator de risco: os que afirmaram não usá-lo apresentaram “odds ratio” (OR) bruto de 0,70, e de 0,73 quando ajustado para visitas regulares ao dentista. O efeito para as visitas regulares ao dentista foi de risco. Pessoas com história de cárie visitavam mais os profissionais. Aqueles com história de cárie apresentaram um “odds ratio” bruto de 1,55; após o ajuste para uso de fio dental o risco foi levemente superior (OR = 1,67). Hábitos de higiene oral não demonstraram efeito protetor esperado. O uso de fluoretos não esteve significativamente associado à ausência de cáries. Permanece intrigando o fato de que algumas pessoas não desenvolvam cáries, mesmo não relatando cuidados considerados ideais à saúde bucal.; The purpose of this article was to investigate the effect of personal awareness and attitudes...

A odontologia ao longo da história pautou-se na evolução do processo saúde/doença e, nas últimas décadas, vem assistindo o declínio da atividade da principal doença bucal, a cárie, surgindo assim à necessidade de mudança de sua filosofia, onde novas especialidades foram criadas para inserir o profissional da odontologia na esfera de Promoção de Saúde. Desta forma o Conselho Federal de Odontologia criou a especialidade ?Odontologia do Trabalho? e definiu esta como sendo especialidade que tem como objetivo a busca permanente da compatibilidade entre atividade laboral e a preservação da saúde bucal do trabalhador. O presente trabalho teve como objetivo avaliar a percepção e o conhecimento através de avaliação quali-quantitativa por questionário, relacionado a esta em dois grupos: 1)Formandos do curso de Odontologia do estado do Paraná de Instituições Públicas e Instituições Privadas; 2) Cirurgiões-dentista do estado do Paraná Clínico-geral e Especialistas. Os resultados nos permitiram avaliar que 88,55% dos profissionais e 89,51% dos formandos concordaram com a criação da especialidade. Na questão sobre argumentação para avaliar o conhecimento sobre a especialidade a porcentagem de abstenção da amostra dos profissionais foi de 58...

A analgesia preemptiva consiste na instituição de um regime analgésico previamente ao estímulo nociceptivo, com o objetivo de prevenir a hiperalgesia e a subsequente amplificação da dor. O objetivo deste trabalho foi avaliar a analgesia preemptiva com o lumiracoxibe, inibidor seletivo da cicloxigenase-2 (COX-2), em exodontias bilaterais de terceiros molares mandibulares retidos, comparando-a à analgesia preventiva. Foram selecionados 16 voluntários com bom estado de saúde geral, com indicação para a remoção dos dois terceiros molares mandibulares retidos, em posições simétricas e assintomáticos. O estudo foi delineado de forma duplo-cego e cruzado. Em uma das cirurgias os voluntários foram tratados com lumiracoxibe 400 mg, via oral, em dose única, administrada uma hora antes da cirurgia, seguido da administração de placebo, logo após o término do procedimento. Na cirurgia contralateral, de modo inverso, o tratamento consistiu do uso do placebo antes da intervenção, seguido da administração de lumiracoxibe 400 mg após o término do ato cirúrgico. A eficácia dos regimes analgésicos foi avaliada pelos seguintes parâmetros: tempo decorrido para a tomada do primeiro comprimido de analgésico a partir do final da intervenção; quantidade de comprimidos de analgésico tomada nas primeiras 24 h do pósoperatório; escala visual analógica nos tempos de 4...

PURPOSE: To evaluate an educative and oral health promotion program for children from three public daycare facilities in the city of João Pessoa (PB), in the Northeastern region of Brazil. METHODS: Sample was composed of 219 children who were divided into four age groups: 0 to 12, 13 to 24, 25 to 36 and 37 to 48 months. All children were submitted to clinical exams and preventive procedures of hygiene and topical application of fluoride at 3-month intervals during 12 months. Mothers were given instructions of oral hygiene of their children. The dmft index and the presence of active white spots (AWS) were recorded. RESULTS: Mean (SD) values of the initial and final dmft were 0.65 (1.3) and 0.72 (1.5), respectively (P

This study examined the effects of reinforcement on compliance with an oral hygiene education program. Patients 18 years of age or older who enrolled in an ongoing program at a periodontal practice received 3-5 sessions of instruction in preventive dental care. Using a between-subjects design, patients who entered the program during alternating months also had a portion of their fees refunded contingent upon improvements in their dental plaque scores. Pre- and posttreatment data showed that all subjects exhibited lower plaque levels following the program, but that greater improvements were seen in patients who were exposed to the fee reduction contingency. Plaque scores taken at a 6-month follow-up revealed some relapse for the Fee Reduction subjects. However, their scores were still substantially better than pretreatment, and better than those of the Education only subjects, whose data differed little from untreated Controls. Methodological and practical issues related to behavioral research in preventive dentistry are discussed.

The National Preventive Dentistry Demonstration Program assessed the cost and effectiveness of various types and combinations of school-based preventive dental care procedures. The program involved 20,052 first, second, and fifth graders from five fluoridated and five nonfluoridated communities. These children were examined at baseline and assigned to one of six treatment regimens. Four years later, 9,566 members of this group were examined again. Analyses of their dental examination data showed that dental health lessons, brushing and flossing, fluoride tablets and mouthrinsing, and professionally applied topical fluorides were not effective in reducing a substantial amount of dental decay, even when all of these procedures were used together. Occlusal sealants prevented one to two carious surfaces in four years. Children who were especially susceptible to decay did not benefit appreciably more from any of the preventive measures than did children in general. Annual direct per capita costs were $23 for sealant or fluoride prophy/gel applications and $3.29 for fluoride mouthrinsing. Communal water fluoridation was reaffirmed as the most cost-effective means of reducing tooth decay in children.

Prevention reduces tooth loss, but little evidence supports biannual preventive care for all adults. We used risk-based approaches to test tooth loss association with 1 vs. 2 annual preventive visits in high-risk (HiR) and low-risk (LoR) patients. Insurance claims for 16 years for 5,117 adults were evaluated retrospectively for tooth extraction events. Patients were classified as HiR for progressive periodontitis if they had ? 1 of the risk factors (RFs) smoking, diabetes, interleukin-1 genotype; or as LoR if no RFs. LoR event rates were 13.8% and 16.4% for 2 or 1 annual preventive visits (absolute risk reduction, 2.6%; 95%CI, 0.5% to 5.8%; p = .092). HiR event rates were 16.9% and 22.1% for 2 and 1 preventive visits (absolute risk reduction, 5.2%; 95%CI, 1.8% to 8.4%; p = .002). Increasing RFs increased events (p < .001). Oral health care costs were not increased by any single RF, regardless of prevention frequency (p > .41), but multiple RFs increased costs vs. no (p < .001) or 1 RF (p = .001). For LoR individuals, the association between preventive dental visits and tooth loss was not significantly different whether the frequency was once or twice annually. A personalized medicine approach combining gene biomarkers with conventional risk factors to stratify populations may be useful in resource allocation for preventive dentistry (ClinicalTrials.gov...

Ozone has been successfully used in medical field since many years owing to its oxidizing property making it an excellent antimicrobial agent. Moreover its potent anti-inflammatory property along with favorable cellular and humoral immune response made ozone an effective therapeutic agent. Also its ability to arrest and reverse carious lesions in a predictable way opened up a new chapter in minimal intervention dentistry. Furthermore its efficacy in curbing resistant poly microbial root canal flora appears very promising. This article is based on information through valid textbooks, peer reviews, journals and medline/pubmed search.

Large periapical lesions, regardless of whether they are granulomas, abscesses or cysts, are primarily caused by root canal infection. Thus the treatment protocol should be elimination of etiological factors in the root canal system rather than their product, apical true cyst. A 10 year old female patient reported to the Department of Pedodontics and Preventive Dentistry, Dr R Ahmed Dental College & Hospital, Kolkata, with the chief complaint of pain and swelling in relation to upper front fractured teeth. Clinical and radiological findings were suggestive of periapical radicular cyst. Non-surgical endodontic therapy was performed using 1% sodium hypochlorite solution irrigant and Calcium hydroxide intra canal medicament. A 12 months follow-up radiographic examination revealed progressive involution of periapical radiolucency without any clinical symptoms. Periapical cysts respond favorably to non-surgical endodontic treatment and should be considered as primary treatment modality.

Background: Malocclusion should be identified at its earliest before it produces any detrimental effects. The objective of this study is to evaluate the orthodontic status and treatment need of school children in Telangana region, Andhra Pradesh, using Dental Aesthetic Index. Materials & Methods: One thousand children in the age group of 12 - 14 years who fulfilled the inclusion and exclusion criteria were considered. The demographic details of the students along with the information on the orthodontic status were collected using a predesigned questionnaire by a single orthodontist. The information on orthodontic status was obtained using Dentofacial Anomalies with the criteria of Dental Aesthetic Index (W H O Oral Health Assessment form 1997). Results: Results were subjected to ANOVA, Tukeys test and chi square test using SPSS, version 16. 86.1% of the subjects had DAI score of less than 25, suggesting ‘no treatment’; 10% had DAI score of 26-30, suggesting ‘elective treatment’; 3% had DAI score of 31-35, suggesting ‘highly desirable treatment’; 0.9% had DAI score of >36, indicating ‘mandatory treatment’; Higher prevalence of malocclusion among females than males. Conclusion: It is necessary to identify this abnormality at its earliest before it produces detrimental effects. It is also essential to know the prevalence of malocclusion in any society...

Background: Alloys with high nickel content have been increasingly used in dentistry. Alloys have high corrosion rates when exposed to chemical or physical forces that are common intra orally. Titanium is the most biocompatible materials for crowns, fixed partial dentures and implants in the present use, but paradoxically the self-protective oxide film on the titanium can be affected by excessive use of the most common preventive agents in dentistry. Therefore, this study is undertaken in order to draw attention toward the potential effect of prophylactic brushing in a saline medium. Materials and Methods: Forty-five wax patterns in equal dimensions of 10 mm × 10 mm × 2 mm were cast in titanium (Grade II) and nickel-chromium. Of the 45 wax patterns, 15 wax patterns were used for preparing cast titanium samples and 30 wax patterns were used for preparing cast nickel-chromium samples and polished. These samples were divided into three groups of 15 samples each. They are brushed for 48 h each clinically simulating 2 years of brushing in a saline tooth paste medium. The surface roughnesses of the samples were evaluated using profilometer, scanning electron microscopes and energy dispersive spectroscopy. Results were subjected to statistical analysis. Results: The statistical analysis of the Rz and Ra surface roughness values were calculated. Significant difference of surface roughness was present in the titanium samples compared to that of the machine-readable cataloguing and Wirolloy (nickel-chromium) samples after the study. To know the difference in the values of all samples before and after...

This study aims to critically summarize the literature about nano-hydroxyapatite. The purpose of this work is to analyze the benefits of using nano-hydroxyapatite in dentistry, especially for its preventive, restorative and regenerative applications. We also provide an overview of new dental materials, still experimental, which contain the nano-hydroxyapatite in its nano-crystalline form. Hydroxyapatite is one of the most studied biomaterials in the medical field for its proven biocompatibility and for being the main constituent of the mineral part of bone and teeth. In terms of restorative and preventive dentistry, nano-hydroxyapatite has significant remineralizing effects on initial enamel lesions, certainly superior to conventional fluoride, and good results on the sensitivity of the teeth. The nano-HA has also been used as an additive material, in order to improve already existing and widely used dental materials, in the restorative field (experimental addition to conventional glass ionomer cements, that has led to significant improvements in their mechanical properties). Because of its unique properties, such as the ability to chemically bond to bone, to not induce toxicity or inflammation and to stimulate bone growth through a direct action on osteoblasts...
