Hipersensibilidade Dentinária: Diagnóstico E Tratamento

Abstract

A hipersensibilidade é a sensibilidade exagerada da dentina quando exposta ao meio bucal, que se torna permeável à ação de estímulos agressivos. O diagnóstico é feito através da anamnese e da inspeção clínica minuciosa. O tratamento pode ser feito pelo profissional ou pelo próprio paciente sob orientação, dependendo do caso. Ela ocorre comumente no final da terceira década, sendo ligeiramente mais freqüente nas mulheres do que nos homens.<br>Dentin hypersensitivity is an exacerbated sensitivity of dentin when exposed to the oral environment, becoming permeable to the action of aggressive stimuli. Diagnosis is realized through anamnesis and attentive clinical investigation. Treatment is carried out professionally or by the patient himself, depending on the case. Its incidence is common towards the end of the third decade, and it is slightly more frequent in women than in men

The influence of vinegars on exposure of dentinal tubules: a SEM evaluation

“…Dentin hypersensitivity has been described as an exaggerated sensitivity of exposed dentin in response to chemical, tactile or thermal stimuli 16 , where there is not any other form of dental defect or pathology 15 .…”

Improvement of cervical dentin hypersensitivity after two different treatments

“…Products available in the market have different action mechanisms 6,7,10,18,21 . Our study has used fluoride varnish (Fluorniz ® ) and 5% potassium nitrate desensitizer (Nano P ® ), which are able to decrease dentin sensitivity 10,18,21 .…”

Our study has used fluoride varnish (Fluorniz ® ) and 5% potassium nitrate desensitizer (Nano P ® ), which are able to decrease dentin sensitivity 10,18,21 . Our study has not considered the use of control groups, since a positive control group was not applicable, because currently there is no golden standard treatment for DCHS.…”

“…So, dentists should obtain an accurate history, intraoral (mechanical and dehydration tests) and radiological exams to rule out any other clinical condition similar to DCHS. Proposed therapies to improve or eliminate DCHS pain are in general not effective [14][15][16][17][18][19][20][21][22] . In 1935, Grossman 14 has defined requirements for hypersensitivity management to be effective and which are valid to date: biocompatibility, not causing pain, fast and easy to apply, fast action, not staining teeth and being effective in the long term.…”

“…Desensitizing agent based on 5% potassium nitrate (Nano P ® ), on the other hand, in addition to occlusive action, is also classified as agent changing pulp sensory activity, that is, it has neural action 6 . Potassium nitrate present in its composition directly acts on nervous fibers, changing neural components excitability and depolarizing nervous terminations, thus decreasing dentinal sensitivity 10,18,21 . In light of the above, this study aimed at clinically evaluating two treatments to decrease DCHS as well as diagnostic tests and duration of their effects.…”
