Hyperesthesia (from the Greek hyper - increase and aisthesis - sensation) means any increase in pain sensitivity of the tooth tissues to external irritants of temperature, chemical and tactile nature. The number of the patients with hypersensitivity of the hard dental tissues has increased sharply in recent years and according to various authors’ findings it is from 60% to 90%. A wide range of prevalence fluctuations is observed in different age groups. The age of people with certain symptoms of teeth hypersensitivity is 25-50 years while the highest frequency is among the people aged 30-40 years. Starting from an earlier age women suffer more often than men. The generalized form of hyperesthesia is usually associated with such general causes as the functional state of the nervous system, endocrine diseases, disorders of mineral metabolism in the body. The localized forms of hyperesthesia are caused mainly by the defects in the hard tissues of individual teeth or periodontium. Rapid and effective treatment of hyperesthesia of the hard dental tissues is an important and urgent problem of modern practical dentistry. Therefore, a great amount of the techniques for the treatment of this pathology is constantly increasing. Now one of the most common methods is the local impact on the hard dental tissues. The aim of the study is to analyze the specialized medical literature that is concerned with modern methods and techniques for the treatment of hypersensitivity of the hard dental tissues. Materials and methods of the research. The review of the literature sources on modern concepts of the treatment of hyperesthesia of the hard dental tissues has been made and the information has been analyzed. Results. The problem of hypersensitivity of the tooth tissues has led to the invention of a whole class of the drugs aimed at its elimination. These medications have different chemical nature, the mechanism of the action on the tissues and even the indications for their use, but the purpose of all these medical preparations is common as they are aimed at reducing hypersensitivity of the tooth tissues. A wide range of the techniques is proposed to eliminate the problem of tooth sensitivity. One of the most common methods of the treatment is a local effect on the hard dental tissues which is aimed directly at the relief of the hydrodynamic mechanism. According to this theory, the stimulus which causes pain increases the flow of the fluid in the dentinal tubules that leads to the changes in osmotic pressure and increased activity of the nerve endings in its turn. Therefore, taking into account the mechanism of the action of desensitizing toothpastes they are divided into those ones that reduce the excitability of the nerve fiber and those ones that contribute to the obstruction of the dentinal tubules. Nowadays there have been also accumulated a sufficient number of clinical and experimental observations indicating that one of the main causes of dentin hypersensitivity is any disturbance of phosphorus-calcium metabolism of the hard dental tissues. A number of authors have shown that people with the generalized form of hyperesthesia has pronounced hypophosphatemia which is combined with the decrease in the content of inorganic phosphorus and calcium in the oral fluid. In this regard, the drugs of calcium (gluconate, chloride, glycerophosphate) and fluoride (sodium fluoride) are widespread in the treatment of dentin hyperesthesia and they are used by application and rubbing into sensitive areas, electro- and phonophoresis, in the form of varnishes and gels, as well as in toothpastes. Unfortunately, the mechanisms of dentinal pain have not been fully studied and its symptoms are nonspecific and subjective. Therefore, there is no ideal composition for the treatment of sensitive dentin. In addition, the result of the therapy occurs in many cases over a long period of time. Conclusion. Thus, according to modern ideas, the treatment of hypersensitivity of the hard dental tissues can be carried out in two ways: desensitization of the nerve fibers to reduce the corresponding response to irritation; obturation of the dentinal tubules to restore intra-tubular osmotic pressure. These days one hundred percent result in the treatment has not been achieved, so it is important to find and develop new techniques and methods to eliminate teeth hyperesthesia.

“…Dentin hypersensitivity is a dental condition which is defined as a condition with sharp pain caused by extrinsic stimuli on the abnormally exposed dentin surface [1,2]. The etiology of dentin hypersensitivity includes dental caries, gingival recession, chronic trauma from improper brushing, and damage to the gingival tissue after periodontal treatment [3][4][5]. Dentin hypersensitivity reportedly occurs in 8-35% of individuals, mainly in adolescents and adults, and is predominantly more common in women than in men [6].…”

Dentin hypersensitivity is a common disease of the oral cavity, which renders the tooth extremely sensitive to stimuli. These symptoms usually result from the exposure of the dentinal tubules to the external environment. There is a need for a treatment for dentinal hypersensitivity that can overcome the shortcomings of the existing agents. This study thus aimed to assess the therapeutic efficacy of no-ozone cold plasma (NCP), which was developed for safe use in the oral cavity, in conjunction with 1.23% acidulated phosphate fluoride (APF) and hydroxyapatite (HA), which are widely used conventional treatments of hypersensitivity. The fluoride content was evaluated using electron probe micro-analyzer (EPMA) analysis. Moreover, we confirmed the effect of NCP pre-treatment on the dentinal tubule occlusion by APF and HA as follows: scanning electron microscopy and energy dispersive X-ray spectrometry were employed to analyze the exposed dentinal tubules, and the calcium and phosphorus content were measured. Furthermore, an additional experiment was conducted using a metal mesh to analyze the working elements of NCP. All experimental results were analyzed by one-way analysis of variance and then by using the Turkey test as a post hoc test. EPMA analysis confirmed that the fluoride content of the APF and NCP group was significantly higher than that of the APF group (p < 0.001). The fluoride content of the group treated with APF and NCP equipped with a metal mesh was significantly lower than that in the group treated with APF and NCP and the group treated with APF and NCP equipped with a cotton mesh (p < 0.01). Moreover, the group treated with NCP pre-treated with HA and APF exhibited significantly greater dentinal tubule occlusion than the other groups (p < 0.05). The same result was confirmed by calculating the calcium/phosphorus ratio (p < 0.05). Pre-treatment of the enamel and dentin surfaces with plasma improved hypersensitivity by enhancing fluoride deposition with APF and dentinal tubule occlusion with HA.

Введение. В статье рассматривается комплексное лечение некариозных поражений твердых тканей зубов с применением низкоинтенсивного лазера. Цель. Устранить гиперестезию и повысить качество восстановления твердых тканей зубов с дефектами некариозного происхождения с применением низкоинтенсивного лазера. Материалы и методы. Обследовано 50 пациентов в возрасте 25–64 лет (из них 28 женщин и 22 мужчины), обратившихся на амбулаторный прием с жалобами на наличие дефектов твердых тканей зубов и повышенную чувствительность на температурные, химические и тактильные раздражители. Постановку диагноза начинали со сбора анамнеза, оценки стоматологического статуса пациента. Проведена профессиональная гигиена полости рта. Были выявлены супраконтакты и проведена пришлифовка зубов, а также пломб. Сочетали восстановительную терапию и воздействие низкоинтенсивного лазера. В качестве источника лазерного излучения использовали современный аппарат «Вектор-03». Излучателем являлся лазерный диод (номинальная длина волны излучения в максимуме 0,65 мкм, мощность 5 мВт), генерирующий в непрерывном режиме. Методика облучения: контактная, стабильная. Физические параметры: низкоинтенсивное лазерное излучение (НИЛИ) в красном диапазоне спектра, мощность 5 мВт, ППМ ~15 мВт/см2, экспозиция 40 с, доза облучения 0,6 Дж/см2 на одно поле, которое соответствовало диаметру светового пятна (2 мм). Результаты. В результате проведенного комплексного лечения в сочетании с воздействием низкоинтенсивного лазера сразу и через один год после постановки пломб получены следующие результаты: отсутствие болевой реакции на температурные, химические и тактильные раздражители в зубах с некариозными поражениями твердых тканей в 89,7% случаев и сохранение целостности пломб в 92,2% случаев. Заключение. При выявлении некариозных поражений важным моментом является определение стадии заболевания (обострения или ремиссии). В остром периоде осуществляют временную пломбировку стеклоиономерными цементами, а в период ремиссии проводят метод восстановительной терапии композиционными материалами. Воздействие низкоинтенсивного лазера до постановки пломб в значительной степени устраняет гиперестезию и способствует сохранению реставраций на длительный период. Introduction. The article discusses the complex treatment of non-carious lesions of the hard tissues of the teeth using a low-intensity laser. Purpose. Eliminate hyperesthesia and improve the quality of restoration of hard tissues of teeth with defects of non-carious origin using a low-intensity laser. Materials and methods. 50 patients aged 25–64 years were examined (including: 28 women and 22 men) who applied for an outpatient appointment with complaints about the presence of defects in the hard tissues of the teeth and increased sensitivity to temperature, chemical and tactile stimuli. The diagnosis was started with the collection of anamnesis, assessment of the dental status of the patient. Professional oral hygiene was carried out. Supracontacts were identified and teeth and fillings were sanded. Combination of restorative therapy and low-intensity laser exposure. A modern device "Vector-03" was used as a source of laser radiation. The emitter was a laser diode (nominal wavelength of radiation at a maximum of 0.65 microns, power 5 MW), generating in continuous mode. Irradiation technique: contact, stable. Physical parameters: low-intensity laser radiation (LLI) in the red range of the spectrum, power 5 MW, PPM ~15 MW/cm2, exposure 40 s, radiation dose 0.6 J/cm2 per field, which corresponded to the diameter of the light spot (2 mm). Results. As a result of the complex treatment in combination with the effect of a low- intensity laser, good results were obtained immediately and 1 year after the placement of fillings: no pain response to temperature, chemical and tactile stimuli in teeth with non- carious lesions of hard tissues in 89,7% of cases and preservation of the integrity of fillings in 92,2% of cases. Conclusion. When detecting non-carious lesions, an important point is to determine the stage of the disease (exacerbation or remission). In the acute period, temporary sealing with glass ionomer cements is carried out, and during remission, a method of restorative therapy with composite materials is carried out. Exposure to a low-intensity laser prior to the placement of fillings largely eliminates hyperesthesia and contributes to the preservation of restorations for a long period.
