OBJECTIVE: Epidemiological studies have great importance for oral health as they show the prevalence of various diseases in their respective environments, in addition to being able to characterize a given population. The objective of this work is to identify the prevalence of oral lesions in dental clinics of the Faculty of Agricultural Sciences and Health of the Metropolitan Union of Education and Culture (UNIME – Lauro de Freitas) in order to characterize the epidemiological profile of this population.METHODS: The sample was composed by 434 histopathological reports of oral lesions diagnosed from 2003 to 2014, correlating them with the following variables: sex, age, type of biopsy (incisional/excisional), histopathologic diagnosis, clinical suspicion and anatomical location.REULTS: The epidemiological profile of patients affected by oral diseases had high percentage of females (62.9%), with mean age of 39 years, and the most prevalent type of biopsy was the excisional (72.81%). The data showed non-neoplastic proliferative processes as the most prevalent group of lesions (24.2%), followed by odontogenic cysts (17.5%). Lesions were most often presented in the mandible (19.6%), followed by periapex (18.89%), gum (11.75%) and jugal mucosa (9.45%).CONCLUSION: The non-neoplastic proliferative processes can be prevented with simple measures of oral health.
目的：流行病学研究对口腔健康具有重要意义，因为它们除了能够描述特定人群的特征外，还可以显示各种疾病在各自环境中的流行率。这项工作的目的是确定大都会教育和文化联盟农业科学与健康学院（UNIME–Lauro de Freitas）牙科诊所口腔病变的流行率，以确定这一人群的流行病学特征。方法：样本由434份2003年至2014年诊断的口腔病变的组织病理学报告组成，并与以下变量相关：性别、年龄、活检类型（切口/切除）、组织病理学诊断、临床怀疑和解剖位置。结果：口腔疾病患者的流行病学特征中，女性比例较高（62.9%），平均年龄39岁，最常见的活检类型是切除活检（72.81%）。数据显示，非肿瘤性增生过程是最常见的病变组（24.2%），其次是牙源性囊肿（17.5%）。病变最常见于下颌骨（19.6%），其次是根尖周（18.89%）、牙龈（11.75%）和颈黏膜（9.45%）。结论：通过简单的口腔健康措施可以预防非肿瘤性增生过程。

OBJECTIVE: To describe the enamel microabrasion technique used to treat the patient with white stains due dental fluorosis, highlighting the importance of complete anamnesis and clinical examination to achieve the clinical success.CASE DESCRIPTION: patient’s complains, aesthetic self-perception, age, general health, history of excessive intake of fluoride and time of teeth development were considered to the diagnosis and treatment plan. Also, dental trans illumination was used to evaluate the white spots diffusion and estimate the lesion’s length. An abrasive paste mixture of equal parts 37% phosphoric acid and pumice was applied with a wooden spatula in order to perform enamel microabrasion. After the last application, the teeth were polished with finishing discs and a neutral sodium fluoride gel was applied to enamel remineralization. Satisfactory results in the aesthetic improvement were possible with a minimally invasive and cost-effective technique. The dental trans illumination after treatment showed the disappearance of the enamel opacities, preserved on the one-year follow-up.CONCLUSION: Cosmetic dentistry has been increasingly practiced today. However, a correct aesthetic planning should be based on current restorative dentistry concept. For any type of procedure, the dentist should opt for sound tooth structure preservation. This technique might be an efficient alternative to restorative treatments and can be considered a successful procedure. In cases of esthetic alterations due fluorosis, non-invasive methods such enamel microabrasion should be considered before invasive restorative treatments.

OBJECTIVE: This study evaluated in vitro the shear bond strength of experimentally fractured human tooth fragments reattached with different adhesive materials and retentive techniques.METHODS: Forty-eight sound mandibular incisors were randomly divided into 6 groups (n=8). Their incisal edges were cut off in 5 groups, representing an enamel-dentin fracture. Intact teeth were used as control (Group 1). The fragment edges were reattached with adhesive system (Scotch Bond Multipurpose – 3M ESPE) (Group 2), adhesive system and composite resin (ICE – SDI) (Group 3), adhesive system and composite resin with circumferential bevel (Group 4), adhesive system and composite resin with internal dentin groove (Group 5), and adhesive system and composite resin with the circumferential bevel and internal dentin groove (Group 6). Shear bond strength was determined in a universal testing machine. Fracture modes were identified by light microscope. Kruskal-Wallis was used to analysis resistance to fracture and fracture patterns.RESULTS: The results showed statistically significant differences (p<0.05) among groups. The intact teeth (Group 1) showed higher fracture resistance than the other groups. Groups 2 and 6 did not differ and were statistically superior to other techniques. Group 4 presented statistically higher than in Group 5, which in turn was more resistant than Group 3.CONCLUSIONS: None of the fragment reattachment techniques was able to achieve the strength of sound teeth. Fragments reattached only with adhesive system or with adhesive system and composite resin with the circumferential bevel and internal dentin groove showed the best performance for resistance to fracture.
目的：本研究在体外评估了不同粘接材料和固位技术对实验性断裂的人类牙齿碎片的剪切结合强度。方法：将48颗健康的下颌切牙随机分为6组（n=8）。他们的切缘被分为5组，代表牙釉质-牙本质骨折。使用完整的牙齿作为对照（第1组）。碎片边缘用粘合剂系统（Scotch Bond Multipurpose–3M ESPE）（第2组）、粘合剂系统和复合树脂（ICE–SDI）（第3组）、具有周向斜面的粘合剂系统和合成树脂（第4组）、粘合系统和具有内牙本质槽的复合树脂（第5组）重新连接，以及具有周向斜面和内部牙本质凹槽的粘合剂系统和复合树脂（第6组）。剪切结合强度在通用试验机中测定。通过光学显微镜鉴定断裂模式。Kruskal-Wallis用于分析断裂阻力和断裂模式。结果：各组间差异有统计学意义（p<0.05）。完整的牙齿（第1组）显示出比其他组更高的抗断裂性。第2组和第6组没有差异，并且在统计学上优于其他技术。第4组的表现在统计学上高于第5组，而第5组又比第3组更有抵抗力。结论：没有一种碎片再附着技术能够达到健全牙齿的强度。仅用粘接系统或用粘接系统和具有周向斜面和内牙本质凹槽的复合树脂粘接的碎片显示出最佳的抗断裂性能。

OBJECTIVE: to evaluated the influence of two types of low-fusing porcelain glaze application on the surface of a zirconia ceramics stabilized by yttrium (Y-TZP).METHODS: Y-TZP specimens were divided into five groups (n=5) according the surface treatments: control (CO), no treatment was performed; application of a thin low-fusing porcelain glass layer by the powder/liquid technique (GPL); GPL followed by 10% hydrofluoric acid (HF) etching (GPL-HF); glaze spray application (GS); GS followed by 10% HF etching (GS-HF). Roughness measurements contact angle, x-ray diffraction, energy-dispersive spectroscopy (EDS) and scanning electron microscope (SEM) analysis were performed.RESULTS: ANOVA and Tukey tests revealed that GPL had significantly lower contact angle values than the other groups (GPL:50.31º; GPL-HF: 72.73º; GS-HF: 81.73º; CO: 96.48º; GS:101.30º; p=0.001). GPL-HF presented a significant higher roughness (Ra/Rq: 2658.0/3367.0 ηm; p=0.001) than the other groups (GPL: 872.1/1162.0 ηm; GS-HF: 383.0/603.6 ηm; GS: 303.4/391.3 ηm; CO:263.4/339.1 ηm). The X-ray diffraction analysis just tetragonal phase in all groups. EDS and SEM analysis show a highest amount of silica on GPL and GPL-HF surface.CONCLUSION: the application of the low-fusing porcelain glaze by the powder/liquid technique followed by the HF etching promoted a better surface to micromechanical and chemical adhesion.

INTRODUCTION: Ensuring adequate occlusal contacts and anatomy shape and form is always a challenge when placing extensive direct posterior composite resin restorations. The use of a correct technique, such as, an occlusal matrix can reproduce occlusal morphology more precisely. Additionally, recently, silorane-based or bulk fill composite resin present low shrinkage and were specifically designed for restoring posterior teeth.CASE REPORT: This report presents the clinical application of a low shrinkage composite resin system with a preoperative occlusal matrix in extensive composite resin restoration of a molar with hypomineralization. Acrylic resin was applied over the waxed tooth to copy the anatomic details. Cavity was prepared and bonding system was applied. Definitive layer in the occlusal matrix was applied and stabilized in position. Once curing was complete, occlusal matrix and resin excess were removed using a surgical blade.CONCLUSION: The application of these materials with occlusal matrix can provide a simpler technical approach, saving time and improving esthetic results.

INTRODUCTION: Radiotherapy for head and neck tumors causes a series of adverse effects. Some effects are temporary, such as oral mucositis and taste disorders, and others are permanent, such as xerostomia and increased risk for dental caries and osteoradionecrosis. One way to diminish radiotherapy’s adverse effects is to decrease the radiation dose on healthy tissues outside the tumor area through more precise radiotherapy techniques, such as intensity-modulated radiation therapy (IMRT), which depends on positioners and stabilizers to the anatomic structures.CASE REPORT: This paper presents direct construction technique examples of mouth openers and positioning stents for tongue and mandible, which allow distance from the radiation field for healthy organs as well the precise stabilization required for the IMRT technique.CONCLUSION: The clinical cases shown in the present paper also illustrate that the intra-oral devices for stabilization of the dental arches and tongue are effective in reducing unnecessary radiation on healthy organs.

INTRODUCTION: The present study identified and described scientific production on primary and secondary prevention of oral cancer worldwide. This is an integrative review of the literature, focusing on the description of oral cancer prevention experiences.METHODS: The search was performed in the Virtual Health Library (VHL), using the descriptors: early diagnosis, oral neoplasms, primary prevention and secondary prevention. We found 225 articles and selected 22 after evaluation, divided into three themes.RESULTS: Four articles awareness-raising and population-tracking campaigns with the valorization of the role of the dental surgeon and the involvement of health teams. The non-invasive diagnostic methods, considered in fifteen articles, addressed the implementation of new strategies for the early detection of this pathology by different diagnostic methods. The reorganization of the health system (3 articles) encompassed the permanent education of oral health professionals, epidemiological surveillance and reorganization of health services with integration of health care levels. The great majority of the reviewed experiences showed positive results in the prevention of oral cancer. An exception was the active search for suspected cases in the population, since the cost benefit did not compensate the expenditure with human resources for this purpose. The non-invasive methods reported are useful for screening but do not substitute the biopsia for diagnosis.

The non-invasive diagnostic methods, considered in fifteen articles, addressed the implementation of new strategies for the early detection of this pathology by different diagnostic methods. The reorganization of the health system (3 articles) encompassed the permanent education of oral health professionals, epidemiological surveillance and reorganization of health services with integration of health care levels. The great majority of the reviewed experiences showed positive results in the prevention of oral cancer. An exception was the active search for suspected cases in the population, since the cost benefit did not compensate the expenditure with human resources for this purpose. The non-invasive methods reported are useful for screening but do not substitute the biopsia for diagnosis.","PeriodicalId":38878,"journal":{"name":"Revista Odonto Ciencia","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.15448/1980-6523.2017.4.28957","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44958134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

OBJECTIVE: This survey assessed the attitudes of dentists regarding dental treatment of children, the barriers reported, and knowledge about the recommended age for a child’s first dental visit.METHODS: A self-applied questionnaire was sent to all dentists in Pelotas/Brazil and 187 (67.8%) were returned. The chi-square test was used to analyze categorical or nominal variables; the chisquare test for linear trend was used for the ordinal variables and Fisher’s exact test was used when the cell frequencies were small. The level of significance was set at α=0.05.RESULTS: The majority of the dentists provide dental treatment for children (123; 71.9%). Regarding the barriers to treatment of children, behavior (55.9%) and interest of parents (48.2%) were the most cited. Only 65.9% reported that children should see a dentist no later than 12 months of age. Knowledge about the recommended age was higher among pediatric dentists (p=0.03) and lower among dentists in private practice (p=0.002) and with more years of practice (p=0.02).CONCLUSIONS: Although most of the dentists treat children, barriers have been pointed out. Many of the dentists are not aware of the recommended age for the first dental visit. Given the benefits of early treatment, this attitude should be stimulated among dental professionals.

This review elucidates the dental structure chemical degradation and saliva roles in the origin and progression of NCCLs. Dentin chemical degradation is a predominant factor that contributes to the origin and progression of noncarious cervical lesions, which includes the biocorrosive factors: chemical, biochemical, electrochemical and piezoelectric dentin effects. The biocorrosive process involves endogenous and exogenous agents. As regard to saliva roles, the flow rate, buffering capacity, pH and its protein composition are valid parameters to identify biocorrosive factors. Thus, the association of acids agents, altered salivary parameters and specifics proteases are important conditions to promote dental wear. It can be concluded that endogenous and exogenous acids agents, salivary parameters and specific oral biomarkers are important to support the diagnostic and management of dental wear and noncarious cervical lesions.
