[01] A presente patente de invenção se refere a uso e dispositivo emissor de luz, a base de LASER DÍODO, operando no comprimento de onda, potência e intensidade específicos, para biomodulação de tecidos e dor em hipersensibilidade dentinária sem uso de agentes químicos e/ou calor sendo um prático, rápido e simples de ser utilizado. The present invention relates to use and light emitting device, based on LASER DYOD, operating at wavelength, specific power and intensity, for tissue biomodulation and pain in dentin hypersensitivity without the use of chemical agents and / or heat being a practical, quick and simple to be used.
[02] Atualmente, a dessensibilização dentinária é considerado procedimento de rotina realizado em consultórios odontológicos, sendo portanto, considerado um procedimento de rotina para a odontologia . [02] Currently, dentinal desensitization is considered a routine procedure performed in dental offices, and is therefore considered a routine procedure for dentistry.
[03] Para entender o seu funcionamento, primeiramente é importante entender como a hipersensibilidade dentinária acontece, o que causa desconforto ou dor. [03] To understand its functioning, it is first important to understand how dentin hypersensitivity happens, which causes discomfort or pain.
[04] Dentina é uma parte do órgão dental que possui canaliculos dentinários preenchidos com terminações nervosas, e portanto, quando expostas a estímulos físicos, químicos ou térmicos geram dor. [05] O órgão dental se divide em duas porções, coroa dental e raiz dental (envolto pelo tecido periodontal ) , e, apresenta basicamente quatro tipos de tecidos distintos: esmalte, cemento, dentina e polpa dental . [04] Dentin is a part of the dental organ that has dentinal canalicules filled with nerve endings, and therefore, when exposed to physical, chemical or thermal stimuli generate pain. The dental organ is divided into two parts, dental crown and dental root (wrapped by the periodontal tissue), and presents basically four different types of tissues: enamel, cementum, dentin and dental pulp.
[06] Em condições fisiológicas, o que promove a proteção da dentina em sua porção coronária é o esmalme dental, e, em porção radicular é o cemento dental, envolto pelo tecido periodontal. [06] In physiological conditions, what promotes the protection of the dentin in its coronary portion is the dental enamel, and, in radicular portion is the dental cementum, wrapped by the periodontal tissue.
[07] Como a dentina é o tecido subjacente ao esmalte e cemento, qualquer ruptura destes últimos, promovem exposição dos canaliculos dentinários, estes, expostos a agentes físicos, químicos ou térmicos geram dor. As dentin is the underlying tissue to the enamel and cement, any rupture of the latter, promote exposure of dentinal canaliculos, exposed to physical, chemical or thermal agents generate pain.
[08] Técnica de escovação inadequada, procedimentos de raspagem periodontal, traumas de mastigação, são caracterizados agentes físicos que promovem a retração do tecido gengival periodontal, consecutiva perda de cemento radicular e exposição dos canaliculos dentinários. [08] Inadequate brushing techniques, periodontal scaling procedures, chewing traumas, are characterized physical agents that promote the retraction of periodontal gingival tissue, consecutive loss of root cementum and exposure of dentinal canaliculi.
[09] A constante exposição do órgão dental a alimentos ricos em ácidos (ex: frutas cítricas, refrigerantes ) e a doença periodontal (considerado biocorrosão) , são caracterizados agentes químicos que promovem desgaste do esmalte e cemento dental, respectivamente, e exposição dos canaliculos dentinários . The constant exposure of the dental organ to acid-rich foods (eg citrus fruits, soft drinks) and periodontal disease (considered bio-corrosion), are characterized chemical agents that promote enamel and dental cement wear, respectively, and exposure of dentinal channels.
[010] Considerado os feitos citados, qualquer agente térmico, fisico ou químico em contato com o órgão dental e com exposição dentinária, possui maior probabilidade de apresentar hipersensibilidade dentinária e até dor. [010] Considering the facts cited, any thermal, physical or chemical agent in contact with the dental organ and with dentin exposure is more likely to have dentine hypersensitivity and even pain.
[011] Para eliminar a dor, hipersensibilidade ou desconforto do paciente é necessário a remoção total de terminações nervosas do elemento dental. Contudo, efetuar a extirpação do nervo nem sempre é a terapia mais indicada, a solução é promover analgesia por ação de feixe de luz laser de baixa potência. [011] To eliminate the pain, hypersensitivity or discomfort of the patient is necessary the total removal of nerve endings from the dental element. However, performing nerve excision is not always the most indicated therapy, the solution is to promote low-power laser beam analgesia.
[012] A luz laser incidida no elemento dentário produz alterações na rede de transmissão neural dentro da polpa dentária, deprime a transmissão nervosa, induz a produção de beta endorfinas, cessando o desconforto ou dor. As técnicas atuais de dessensibilização dentinária com diodo laser não cirúrgico e de baixa potência, realizam a depressão de transmissão nervosa através de fontes de luz que operam em comprimento de onda entre 635 a 850 nm, sendo ou não associadas ao uso de agentes químicos obliteradores de canais dentinários ou de ação neural . [013] O mais comum e usual destes agentes é o Fluoreto de Sódio (NaF - obliterador de canal dentinário) . O mecanismo para redução da hipersensibilidade envolve a penetração de fluoreto nos canaliculos expostos e consequente cristalização da molécula. Laser light on the dental element produces changes in the neural transmission network within the dental pulp, depresses nerve transmission, induces the production of beta endorphins, and discomfort or pain ceases. Current techniques of non-surgical and low power laser diode desensitization perform nerve transmission depression through light sources operating at wavelengths between 635 and 850 nm, whether or not associated with the use of chemical obliteration agents dentinal or neural action channels. [013] The most common and usual of these agents is Sodium Fluoride (NaF - dentin channel obliterator). The mechanism for reducing hypersensitivity involves the penetration of fluoride in the exposed ducts and consequent crystallization of the molecule.
[014] Normalmente a temperatura da cavidade bucal seria suficiente para manutenção da reação, porém o processo é acelerado com a presença de luz, quando se converte energia luminosa em térmica, gerando perda de água intrinsica da dentina, remoção de proteínas e aumento dos cristais de hidroxiapatita presentes no elemnto dental. Normally the temperature of the buccal cavity would be enough to maintain the reaction, but the process is accelerated with the presence of light, when it converts light energy to thermal, generating intrinsic loss of water of the dentin, removal of proteins and increase of crystals of hydroxyapatite present in the dental element.
[015] Geralmente, o procedimento envolve aplicar o gel (à base de NaF) na região de dentina, na sua superfície externa e aguardar o tempo para sua penetração na estrutura dental. Este processo é atualmente empregado na odontologia a nível mundial . Generally, the procedure involves applying the NaF-based gel to the dentin region on its outer surface and waiting for the time for its penetration into the dental structure. This process is currently employed in dentistry worldwide.
[016] Diversos dispositivos fonte de luz foram desenvolvidos e consequentemente tiveram suas patentes requeridas com o objetivo de uso isolado ou em consonância com agentes químicos em forma de gel ou líquido. [017] O documento patente número 0501487-5 A (BR) , refere-se ao uso simultâneo de luz led e laser para terapia de clareamento dental e biomodulação de tecidos envolvidos, não demonstrando e não referenciando a sua utilização ou eficácia de uso sem a utilização de luz led e gel clareador (agente químico) , não sendo portanto, dedutível ao estado da técnica a sua utilização sem o uso de agentes químicos e exposição prévia a luz led. Various light source devices have been developed and consequently had their patents required for the purpose of use alone or in consonance with chemical agents in the form of gel or liquid. Patent document number 0501487-5 A (BR), relates to the simultaneous use of led and laser light for dental bleaching therapy and biomodulation of involved tissues, not demonstrating and not referring to their use or efficacy of use without the use of led light and bleaching gel (chemical agent), therefore, it is not deductible to the state of the art its use without the use of chemical agents and previous exposure to led light.
[018] O documento de patente 6,976,841 BI (US), refere-se a um sistema eletro óptico em formato de moldeira para clareamento dental, ativação e cura resultante de materiais líquidos e semi-líquidos utilizados em aplicações dentárias comerciais, não demostrando e não referenciando a sua utilização ou eficácia para uso no tratamento de hipersensibilidade dentinária, não sendo portanto, dedutível ao estado da técnica a sua utilização para tratamento da hipersensibilidade dentinária. Patent document 6,976,841 BI (US), relates to an electro-optical system in tray format for dental whitening, activation and curing resulting from liquid and semi-liquid materials used in commercial dental applications, not demonstrating and not referring to its use or efficacy for use in the treatment of dentin hypersensitivity, and therefore, it is not deductible to the state of the art for its use in the treatment of dentine hypersensitivity.
[019] O documento de patente 10-1045182 (KR), sob registro publicação Internacional N° WO 2004/028626, refere-se a um sistema eletro óptico em formato de moldeira, específico para clareamento dental utilizando agente químico para procedimento, não demostrando e não referenciando a sua utilização ou eficácia para uso no tratamento de hipersensibilidade dentinária, não sendo portanto, dedutível ao estado da técnica a sua utilização para tratamento da hipersensibilidade dentinária. [019] Patent document 10-1045182 (KR), under International Publication No. WO 2004/028626, relates to an electro-optical system in tray format, specific for dental bleaching using chemical agent for procedure, not demonstrating and not referring to its use or efficacy for use in the treatment of dentine hypersensitivity, deductible to the state of the art its use for the treatment of dentin hypersensitivity.
[020] Há, no entanto, uma série de problemas associados ao processo/procedimento existentes para aplicação de agentes químicos em forma de gel ou líquido, associados ou não ao laser. Do ponto de vista operacional, deve ser efetuado isolamento relativo da região dentária com auxílio de roletes de algodão, aplicar do gel e aguardar cerca de 04 minutos para que haja a penetração das moléculas a fim de começar o processo. Esta incubação expõe a estrutura dental e tecidos adjacentes por período relativamente médio aos agentes químicos, o que pode promover reações alérgicas devido a associação de corantes na formulação dos agentes químicos. [020] There are, however, a number of problems associated with the existing process / procedure for the application of chemical agents in the form of gel or liquid, associated or not to the laser. From the operational point of view, the relative isolation of the dental region should be carried out using cotton rollers, apply the gel and wait about 04 minutes for the molecules to penetrate in order to begin the process. This incubation exposes dental structure and adjacent tissues for a relatively medium period to chemical agents, which may promote allergic reactions due to the association of dyes in the formulation of chemical agents.
[021] Outro problema importante que existe neste método convencional é a dificuldade de penetração do gel em região sub gengival, em casos onde o "vedamento gengival" (promovido pelos hemi- desmossomas presentes no tecido periodontal) ao redor do elento dentário, encontra-se comprometido. Neste contexto, é evidente a limitação da técnica com o uso de agentes químicos em forma de gel ou líquido, o que, torna a aplicação deste procedimento menos eficaz. Como resultado, este procedimento deve ser repetido por várias vezes, o que, demanda maior tempo do profissional envolvido. [022] Apesar de apresentar menor incidência de hipersensibilidade dentinária, devido a estrutura dental tender a possuir maior conglomerado de dentina terciária ou reparadora, pessoas com mais idade apresentam microtrincas na superfície do dente. Neste caso, ao se aplicar o gel, existe a dificuldade de penetração, relacionado a maior viscosidade . [021] Another important problem that exists in this conventional method is the difficulty of gel penetration in the sub gingival region, in cases where the "gingival seal" (promoted by the hemi-dermosomes present in the periodontal tissue) around the tooth, was committed. In this context, the limitation of the technique is evident with the use of chemical agents in the form of gel or liquid, which makes the application of this procedure less effective. As a result, this procedure must be repeated several times, which, demands more time from the professional involved. Despite having a lower incidence of dentin hypersensitivity, because the dental structure tends to have a greater tertiary or repairing dentin conglomerate, older people have micro-incisions on the surface of the tooth. In this case, when applying the gel, there is the difficulty of penetration, related to higher viscosity.
[023] Como estes problemas são causados pelo gel e pensando em eliminá-los foi que desenvolveu a presente patente, onde, a parte essencial do tratamento para hipersensibilidade dentinária corresponde em deprimir a transmissão nervosa através de apenas um fenómeno físico, ou seja, o uso de um emissor de luz com comprimento de onda, potência e intensidade específicos, sendo estes o ponto essencial e mais importante para a sua eficácia . [023] As these problems are caused by the gel and thinking of eliminating them has been developed the present patent where, the essential part of the treatment for dentin hypersensitivity corresponds in depressing the nerve transmission through only a physical phenomenon, that is, the use of a light emitter with wavelength, specific power and intensity, these being the essential point and most important for its effectiveness.
[024] Utilizando somente esta luz, é capaz de promover grandes excitações elétricas, onde a quantidade de energia introduzida na molécula é capaz de aumentar a eficiência da bomba Na++ e K+, presentes durante a excitação nervosa, e, interagente com a luz, mantém a diferença de potencial elétrico existente entre o interior e o exterior da célula, o que proporciona a analgesia. [025] O processo de dor na hipersensibilidade dentinária inicia-se com a excitação nervosa, que, desencadeia a ativação da bomba de NA++/K+, o que, gera a despolarização da membrana plasmática do neurônio, perfazendo o meio intracelular com carga positiva . Using only this light, it is able to promote great electrical excitations, where the amount of energy introduced in the molecule is able to increase the efficiency of the pump Na ++ and K + , present during the nervous excitation, and, interacting with the light, maintains the difference in electrical potential between the inside and outside of the cell, which provides analgesia. The process of pain in dentin hypersensitivity begins with nervous excitation, which triggers the activation of the NA ++ / K + pump, which generates the depolarization of the plasma membrane of the neuron, making up the intracellular environment with positive charge.
[026] A dinâmica celular se inicia pelo retículo endoplasmático com a produção de neurotransmissores /neuropepitídeos (substância P) , estes, são envoltos em vesículas no complexo de golgi e direcionados a porção axonal do neurônio. Através da ação do Ca++, os neurotransmissores são liberados, unindo-se ao receptor neuroquinina K. Esse processo se repete em cada neurônio até chegar em área de gânglio trigeminal . Uma porção deste, se une a outros nervos somestésicos primários, no leminisco espinhal, e a informação é direcionada ao tálamo perfazendo a sinapse no núcleo ventro posterior lateral, e, através do trato tálamo cortical, chega a área somestésica primária no córtex, cuja informação é dor ou hipersensibilidade. Cellular dynamics are initiated by the endoplasmic reticulum with the production of neurotransmitters / neuropeptides (substance P), these are enveloped in vesicles in the golgi complex and directed to the axonal portion of the neuron. Through the action of Ca ++ , the neurotransmitters are released, joining the neurokinin K receptor. This process is repeated in each neuron until reaching the trigeminal ganglion area. A portion of this connects to other primary somesthetic nerves in the spinal lemniscus, and the information is directed to the thalamus making the synapse in the lateral posterior ventro nucleus, and, through the cortical thalamus treatment, the primary somesthetic area in the cortex arrives. is pain or hypersensitivity.
[027] Com o intuito de superar e inovar em procedimentos para tratamento da hipersensibilidade dentinária, foi que desenvolveu a presente patente de invenção a qual consiste de um dispositivo emissor de luz, á base de DÍODO LASER, operando no comprimento de onda, potência e intensidade específicos, para inibição/biomodulação de impulsos em terminações nervosas e tecidos dentais adjacentes, sem o uso de agentes químicos ou calor, sendo prático, rápido e simples de ser utilizado. In order to overcome and innovate in procedures for the treatment of dentin hypersensitivity, it has been developed the present invention patent which consists of a light emitting device, based on LASER DYOD, operating on the wavelength, power and intensity specific for inhibition / biomodulation of impulses in nerve endings and adjacent dental tissues, without the use of chemical agents or heat, being practical, quick and simple to be used.
