ABSTRACT Numerous pathogens, including SARS-CoV-2, can remain viable on surfaces over days, which favors cross-contamination. Preventive measures are essential to prevent infections and control the spread of COVID-19. Fox ruler is an essential device in the clinical planning of complete dentures and the contact with the patient’s oral fluids during handling is unavoidable. Despite its importance, the conventional polycarbonate Fox ruler is easily damaged in the sterilization process. Therefore, the purpose of this article is to propose the use of a disposable Fox ruler. The confection is carried out in a simple way with wooden toothpicks joined by cyanoacrylate glue, following the same shape as the conventional one, but with the additional advantage of being made in an individual size according to the upper edge. The proposed disposable Fox ruler makes it possible to obtain the parallelism of the upper wax roller with the bipupillary line and with the Camper plane. Therefore, the disposable device described in this article was able to perform the same functions as the conventional one, in a practical way, without risks of cross contamination and with low cost.

ABSTRACT Objective: The study and enactment of dental preventive measures, in response to the COVID-19 pandemic, are necessary to prevent cross-infections between professionals and patients. The objective of this integrative review was to identify the COVID-19 preventive practices in dentistry. Methods: The electronic search was conducted on these databases: Pubmed / Medline, Web of Science, Cochrane Library, Scopus, LILACS and Scielo, using the following descriptors and / or words: “Coronavirus disease 2019”; “Coronavirus 2019”; “Covid-19”; “2019-ncov”; “Sars-cov2”; “Dental practice”; “Dental care”; “Dentistry”; “Dental medicine” and “Oral medicine”. PRISMA was used as a reference for designing it. Results: A total of 11 articles were included and the preventive measures against COVID-19 were based on guidelines from health agencies and consisted of: perform only emergency treatments; reschedule patients with suspected disease; hand washing; disinfection of surfaces with 70% alcohol; testing dental professionals for the disease; use the N95 mask; disposable lab coats, and face shields. Children, in addition to the measures mentioned above, should routinely drink a lot of water and be provided with healthy diets. No study has evaluated the efficacy and effectiveness of these measures. There is a lack of scientific evidence on the preventive protocols adopted against COVID-19 in dentistry since preventive measures are recommended by health agencies. Conclusion: Consequently, professionals are recommended to follow the guidelines by these organizations until effective and efficient preventive protocols tailored to dentistry are established.
摘要目的:研究和制定应对新冠肺炎大流行的口腔预防措施，防止医护人员与患者之间的交叉感染。本综合综述的目的是确定牙科中的COVID-19预防措施。方法:在Pubmed / Medline、Web of Science、Cochrane Library、Scopus、LILACS和Scielo数据库中进行电子检索，使用以下描述词和/或词:“冠状病毒病2019”;“冠状病毒2019”;“Covid-19”;“2019 - ncov”;“Sars-cov2”;“牙科实践”;“牙科保健”;“牙医”;“牙科医学”和“口腔医学”。采用PRISMA作为设计参考。结果:共纳入11篇文章，针对COVID-19的预防措施基于卫生机构的指南，包括:只进行紧急治疗;重新安排疑似病人的就诊时间;洗手;用70%酒精消毒表面;对牙科专业人员进行疾病检测;使用N95口罩;一次性实验服和面罩。儿童除了采取上述措施外，还应经常大量饮水，并提供健康的饮食。没有研究评估过这些措施的功效和效果。由于预防措施是卫生机构建议的，因此缺乏关于牙科采用的COVID-19预防方案的科学证据。结论:因此，建议专业人员遵循这些组织的指导方针，直到针对牙科建立有效和高效的预防方案。

ABSTRACT The diagnosis and treatment of supernumerary teeth pose a challenge for dental clinicians and pediatric dentists. These teeth are asymptomatic and may cause the delayed eruption of the permanent dentition, altered bone growth and ectopic positioning. This paper reports a case of the surgical removal of supernumerary teeth in the anterior region of the maxilla of a child under general anesthesia in a hospital setting. A six-year-old female patient visited a private dental office in the city of Garanhuns, Brazil, accompanied by her mother, who reported a tooth with a “strange shape” in the anterior region as the main complaint and also reported that her daughter’s first dental experience was negative. The clinical examination and imaging tests were performed under general anesthesia to confirm the diagnosis. In view of the patient’s dental and behavioral history, surgical treatment was performed in a hospital setting and assisted by a multidisciplinary team. Care in the hospital setting was found to be feasible, providing greater comfort for uncooperative patients.

ABSTRACT Objective: To analyze the dental equipment microbial contamination and to test different disinfectants, collaborating with the protocols control of cross infection in dental care. Methods: Samples were collected from dental equipment (syringes; auxiliary table; reflector), cultured in Petri plates with Brain Heart Agar (for bacteria) and Sabourad Agar (for fungi) culture medium. After collection of the initial samples, the surfaces were randomly divided and disinfected with the following products: ethanol 70% (A70); 5% chlorhexidine (CHX5) and, glucoprotamina 0.5% (GLP0,5). New sample collections were made from the same locations described above (final samples). Results: No disinfectant product tested was able to eliminate all microbial forms (bacteria and fungi) surfaces. For bacteria, the antimicrobial activity was higher with the ethanol 70%, followed by 5% chlorhexidine and glucoprotamina 0.5%. For fungi, the 5% chlorhexidine had the best effect, followed by ethanol 70% and glucoprotamina 0.5%. Conclusion: The study confirmed the contamination of surfaces of dental equipment and the importance of disinfection for infection control in the dental clinic. Through this study, no antimicrobial agent tested was 100% effective in eliminating microorganisms present in the dental clinic surfaces.

ABSTRACT Objective: The objective of our study was to investigate the relationship between social network and social support with early childhood caries in preschool children. Methods: A transversal study with 100 children aging at most 5 years and 11 months was performed. The children underwent a clinical dental evaluation and their parents answered a structured questionnaire. Results: Dental caries was associated with time of bottle feeding (p=0.031) (RP=5.203) and number of dental appointment (p=0,010) (RP=6,293). Moreover, dental caries was also directly associated with the number of siblings living together in the same house (p=0.002) (r=0.372), while inverse correlation was found between dental caries and social support (p=0.028) (r= - 0.219). Conclusion: Preschool children whose supervisors had a better social support presented superior oral health, suggesting that social support from caregivers is associated with improved pediatric oral health.

ABSTRACT Objective: To evaluate the knowledge of orthodontic professionals regarding the prescription of dentifrices and antiseptics during orthodontic treatment. Methods: An observational and descriptive exploratory study of national scope was conducted with 440 Brazilian orthodontists, based on previous sample calculations, to evaluate the clinical practice of orthodontists in prescribing dentifrices and antiseptics. Self-managed electronic questionnaires were sent to orthodontic professionals. The data were analyzed by means of absolute and relative frequency distribution tables. Results: It was verified that the most indicated mouthwash (39.8%) was Colgate Periogard® and 421 of the participants (95.7%) know its active ingredient (chlorhexidine digluconate). Besides Colgate Periogard® antiseptic, the participants were also questioned about which active ingredient present on the following antiseptics, whose assertive answers were in the following order of %, Cepacol® (Sanofi-Aventis®) with 60.7%, Colgate Plax® (Colgate®) with 54.5% and Listerine® (Jhonson&Jhonson®) with 51.6%. As for the chlorhexidine therapeutic regime, 63.9% have stated assertively its use, being this one of 2 times a day during 7 to 10 days. The most indicated tooth was Colgate Total 12®, and 60.18% of these individuals correctly indicated its active compound. Conclusion: According to the methodology employed, it could be concluded that orthodontic professionals know and prescribe methods of chemical control to patients during orthodontic treatment and most identify the active chemical compounds present in antiseptic and tooth formulas.

ABSTRACT The aim of this study was to report a rare case of an asymptomatic calcification of unusual size and shape, inside the maxillary sinus identified on a cone beam computed tomography exam and to discuss the importance of knowledge of the anatomy of maxillary sinus and its changes carefully evaluating the entire volume of the images, regardless of the region of interest. An 83-year-old female patient underwent a cone beam computed tomography exam for other diagnostic purposes in the maxillofacial region. When analyzing the entire volume, an image of unusual limits, hyperdense and calcified was found in the right maxillary sinus, close to the anterior and medial wall, with a rounded and homogeneous shape, occupying approximately one third of the maxillary sinus. There was no lytic or erosive lesions on the maxillary sinus wall. The main diagnostic hypotheses raised were giant anthrolith, mucous retention phenomenon and osteoma. Due to the anatomical complexity of the maxillary sinus, diagnosis in this region becomes a challenge. Considering the limitations of 2D exams, the cone beam computed tomography exam can be used to evaluate these structures. Knowledge of differential hypotheses is extremely important for the case to be conducted correctly, but it does not replace biopsy and histopathological examination.

ABSTRACT Guided bone regeneration aims to gain vertical and horizontal bone volume in atrophic ridges, using different regenerative techniques associated with biomaterials, with occasional post-surgical complications. The objective of the case report was to describe the successive approaches to minimize and eliminate the complications presented in the postoperative period of a patient submitted to the guided bone regeneration technique. In the first surgery, the dense expanded polytetrafluoroethylene membrane (d-PTFE), supported by the tent technique and autogenous platelet graft, was used to perform the guided bone regeneration technique. After three months, the membrane was exposed, with the membrane and the retaining screws removed in the seventh month, with the installation of three Internal Hexagon implants in the areas of teeth 13, 14 and 15. The exposed threads were covered with hydroxyapatites resorbable and covered with d-PTFE membrane. A four-month postoperative panoramic radiograph suggested implant osseointegration. The guided bone regeneration technique associated with the d-PTFE membrane enabled bone neoformation, enabling the installation of osseointegrated implants in an aesthetic and functional position. The exposure of the edges of the membrane allowed the penetration of fluids and contamination, suggesting the worsening of the signs of infection and purulent secretion. On the contrary, the exposure of central areas did not cause inflammatory and infectious signs.

The objective of the case report was to describe the successive approaches to minimize and eliminate the complications presented in the postoperative period of a patient submitted to the guided bone regeneration technique. In the first surgery, the dense expanded polytetrafluoroethylene membrane (d-PTFE), supported by the tent technique and autogenous platelet graft, was used to perform the guided bone regeneration technique. After three months, the membrane was exposed, with the membrane and the retaining screws removed in the seventh month, with the installation of three Internal Hexagon implants in the areas of teeth 13, 14 and 15. The exposed threads were covered with hydroxyapatites resorbable and covered with d-PTFE membrane. A four-month postoperative panoramic radiograph suggested implant osseointegration. The guided bone regeneration technique associated with the d-PTFE membrane enabled bone neoformation, enabling the installation of osseointegrated implants in an aesthetic and functional position. The exposure of the edges of the membrane allowed the penetration of fluids and contamination, suggesting the worsening of the signs of infection and purulent secretion. On the contrary, the exposure of central areas did not cause inflammatory and infectious signs.","PeriodicalId":30069,"journal":{"name":"RGO Revista Gaucha de Odontologia","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76401458","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}

ABSTRACT Oral amyloidosis is a disease characterized by extracellular and irreversible deposition of amorphous and fibrillar proteins in the oral cavity, being strongly associated with Multiple Myeloma. The objective of this study is to report a case of a 62-year-old woman diagnosed with Multiple Myeloma who, approximately 2 years after starting treatment for the underlying disease, presented a lesion on the lateral border of the tongue with exophytic growth, pinkish color, vascularized, painless, measuring 3cm in its largest diameter. After histopathological analysis through incisional biopsy, a final diagnosis of amyloidosis was obtained. As a local treatment, we opted for complete excision of the lesion. The patient evolved to death due to Multiple Myeloma influenced by the diagnosis of systemic amyloidosis. Oral amyloidosis is usually associated with the systemic presentation of the disease, making it necessary to conduct a thorough investigation of other organs. Its diagnosis is important since the prognosis is directly related and can negatively influence survival rates and treatment of the underlying disease.
