Products of Dental Use Containing Copaiba Oil-resin: Technological Prospecting Based on Patents.

BACKGROUND: Copaiba oil-resin has been widely used and is especially found in neotropical regions, for which several pharmacological activities have been documented over the years. Prospective studies in intellectual property banks are important to increase competitiveness and thus generate new products in various research areas. OBJECTIVE: A prospective study was carried out on patents of products containing copaiba oil-resin for dental use in intellectual property banks. METHODS: The research was conducted with patent searches in six intellectual property banks of the world. Relevant information about the invention in the patent document was collected, processed and described. RESULTS: The search found 9 patents using copaiba resin oil-resin in dental products. The National Institute of Industrial Property (INPI-Brazil) had the highest number of deposits (5), followed by Espacenet (2) and Free Patents (2). C. Langsdorffii was highlighted as the most widely used species in the products and deposits of vehicles in formulations (3). All the patents in the search are A61K code for medical, dental or hygienic purposes. CONCLUSION: Most of the found patents are related to the area of Microbiology, specifically with application in Cariology. Brazil is represented by the INPI and presented the highest number of patent applications when compared to other intellectual property banks.

Propolis and its Dental Applications: A Technological Prospection.

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.
