RESUMEN
PURPOSE: This study aimed to evaluate reports of patents for oral care formulations, based on Camellia sinensis (C. sinensis), deposited and granted in intellectual property banks. METHODS: A survey was conducted through collection, treatment, and analysis of extracted information from patent reports selected. The documentary research was conducted in January 2021 on formulations with C. sinensis for dental applications, including since the first patent deposits until the current time. The risk of bias of clinical trials with these formulations was analyzed to verify the scientific evidence. The data extracted represent the distribution of the number of patents by banks, annual evolution of patent deposits, applicant of patents by country, distribution of patents according to International Patent Classification codes, and the types of patented products. RESULTS: Data and information from 20 selected patents were extracted. The United States Patent and Trademark Office (USPTO) and World Intellectual Property Organization (WIPO) were the banks with the largest number of patents for products/formulations with C. sinensis for oral care applications with 7 (35%) and 6 (30%) patent registrations, respectively. Other banks did not provide patents related to the search. Patents of compositions were the largest with 14 filings, and the remainder of formulations are represented specially by mouthwashes and toothpastes. As for clinical application, 18 patents were filed as products with antimicrobial and antibiofilm action, while 2 patents are directed to the treatment of xerostomia. In general, the aspects of the studies of clinical efficacy pointed to a low risk of bias. CONCLUSION: The study pointed out a small number of products protected by patents for Camellia sinensis for oral care indication, highlighting mainly mouthwash compositions and formulations. In the methodological parameters of clinical trials carried out with the formulations, the majority pointed out a low risk of bias.

BACKGROUND: Propolis is a resinous complex produced by Apis mellifera L. bees whose variety of pharmacological properties results from the complexity of its composition. In dentistry, propolis is used on the prevention of oral diseases such as dental caries and gingivitis. Prospective studies in intellectual property banks are important to increase market competitiveness and thus generate new products in the various research areas. In this way, investments in patents play an important role in the technological and economic development of a country. OBJECTIVE: To evaluate patents with dental products containing propolis, on intellectual property banks. METHOD: The research was conducted in 10 banks of intellectual property, including since the first deposits up to 2016. Relevant information that describes the invention in the patent document were collected, processed and described. RESULTS: The search performed in 62 patents using propolis in the dental topic. World Intellectual Property Organization (WIPO) has the largest number of filing patents (83.60%) and the National Institute of Industrial Property (INPI) in third place with 4 patents (6.55%). Built-in dental cream with propolis was the most patented product. The first patent date of 1998, followed by an increase in the number of deposits in the last 20 years. Most of the patents are A61K code (51) for medical, dental or hygienic purposes. CONCLUSION: This study has shown that propolis is a promising bioactive component in dental products, especially for use in Cariology and Periodontology. Although there has been a significant progress in applications of propolis, the field of dental products is still a growing area and it is important to encourage innovation and development of new products incorporating propolis based on knowledge of its composition and therapeutic properties.

ABSTRACT Immediate esthetic rehabilitation is a common practice in contemporary restorative dentistry. Sometimes without a precise diagnosis and clinical planning, two or three clinical sessions have been sufficient to start and end an extensive all-ceramic oral rehabilitation. It is essential, however, for these treatments to be based on the biological, mechanical, and occlusal principles that have been established for decades, and not only on aesthetic considerations. In this case report, a 26 year-old bruxist patient with functional and aesthetic needs, was rehabilitated with ceramic restorations in the six maxillary anterior teeth, through an interdisciplinary approach. The diagnostic wax-up was essential to predict the outcome; guide the periodontal surgery; serve as a reference for dental preparations, and restore the dynamics of jaw movements. After the adhesive cementation, a protective occlusal splint for use during sleep was introduced. The authors concluded that careful diagnosis and planning was critical to outcome of this case, and that the quality and longevity of restorative treatment depended on the respect for biomechanical, occlusal, and aesthetic concepts.
RESUMO Reabilitações estéticas imediatas são práticas frequentes na Odontologia restauradora atual. Por vezes, sem um diagnóstico e um planejamento clínico preciso, duas ou três sessões clínicas têm sido o bastante para iniciar e finalizar uma reabilitação oral extensa totalmente cerâmica. Contudo é fundamental que esses tratamentos voltem a ser sustentados por princípios biológicos, mecânicos e oclusais básicos, instituídos há décadas, e não apenas por aspectos estéticos. No presente relato de caso, uma paciente de 26 anos, bruxista, com necessidades funcionais e estéticas, foi reabilitada com restaurações cerâmicas nos 6 dentes anteriores superiores, por meio de uma abordagem interdisciplinar. O enceramento diagnóstico realizado foi fundamental para prever o resultado, guiar a cirurgia periodontal, servir de referência para os preparos dentais e restaurar a dinâmica dos movimentos mandibulares. Após a cimentação final das restaurações, a proteção com placa oclusal no período do sono foi instituída. Concluiu-se que um criterioso diagnóstico e planejamento foi fundamental para o desfecho do caso, e que a qualidade e a longevidade desse tratamento restaurador parece depender intimamente do respeito aos conceitos biomecânicos, oclusais e estéticos.
RESUMEN
A prótese parcial removível a grampo (PPRG) possibilita reabilitar áreas parcialmente edêntulas, restaurando a função mastigatória, estética e fonética. Apesar dos avanços da Odontologia observados nas últimas décadas, estudos indicam que a higiene bucal dos pacientes usuários de PPRG ainda é precária. Desse modo, o objetivo desse estudo foi verificar os hábitos de higienização das próteses e cavidade bucal, bem como o nível de satisfação dos pacientes usuários de PPRG atendidos na Universidade Federal do Ceará (UFC). Trata-se de um estudo descritivo, quantitativo onde foi aplicado um questionário a 31 pacientes usuários de PPRG. Os dados foram analisados através do teste qui-quadrado e expressos na forma de frequência absoluta e percentual considerando uma confiança de 95%. Da amostra, a maioria (77,4%) era do gênero feminino, com idade entre 40 a 60 anos, (64,5%) possuíam ensino médio completo e haviam recebido orientações de higiene após a instalação da prótese (96,8%). O método de higienização mais utilizado foi a escovação mecânica com dentifrício. Quanto à frequência de higienização, 71% responderam realizá-la 3 ou mais vezes ao dia. A cárie foi apontada como o principal fator etiológico das perdas dentárias, apresentando uma diferença significativa em relação ao grau de satisfação dos pacientes com a prótese. Verificou-se que a maior parte dos indivíduos está muito satisfeita com o tratamento, embora ainda apresentem falhas na execução dos métodos de higiene bucal e da prótese.
Removable partial denture with clasps (RPDC) restores partially toothless areas, coupled to the chewing, aesthetic and phonetic functions. In spite of progress in dentistry during the last decades, several studies indicate that mouth hygiene of RPDC patients is rather low. Current analysis verifies the hygiene of dentures and mouth cavity and the satisfaction level of patients with RPDC attended by the dentistry school of the Universidade Federal do Ceará, Brazil. Methods: The descriptive and quantitative study comprised a questionnaire to 31 RPDC users. Data were analyzed by χ2 test and expressed in absolute frequency at 95% confidence level. Most subjects (77.4%) were female, aged between 40 and 60 years (64.5%), with complete college. They had received hygiene directions after the installation of the denture (96.8%). The hygiene method most employed was mechanical brushing with dentifrice, three or more times a day, for 71.0% of the interviewed. Caries was the main etiological factor in teeth loss with a significant difference related to the satisfaction degree of patients with the prosthesis. Most subjects were highly satisfied with the treatment even though there were flaws in the execution of mouth and denture hygiene.
