Dentinal sensitivity is characterized by short sharp pain arising from exposed dentin in response to thermal , tactile or chemical stimuli. The most accepted explaination is the hydrodynamic theory , where movement of fluid within dentinal tubules stimulates pulpal nerve endings. Common causes include gingival recession,enamel erosion, abrasion and periodontal therapy.
Management begins with accurate diagnosis to rule out caries or pulpal pathology. Initial treatment focuses on patient education , including proper brushing technique and reduction of acidic food intake . Desensitizing toothpastes containing Potassium nitrate , stannous fluoride or argunine are commonly recommended . In-office treatments such as fluroide varnishes , dentin bonding agents , or glass-ionomer restorations may be used for persistent causes . A stepwise and individualized approach ensures effective system relief and long term control of dentinal hypersensitivity.
Engaging question:
So how you manage dentinal hypersensitivity of your patients ?
