A survey on Dentin hypersensitivity after vital tooth preparation for fixed partial denture
Renu Gupta, Bhuvaneshwari, RP Luthra, Dapinder Brar, Priya sharma, Abhishek

Background: Dentine hypersensitivity is characterized by short, sharp pain arising from exposed dentine in response to stimuli typically thermal, evaporative, tactile, osmotic or chemical and which cannot be ascribed to any other form of dental defect or pathology. The aim of this survey is to gender differences in the incidence of dentin hypersensitivity. Materials & Methods: Subjects: Study population consisted of 30 subjects, 15 men and 15 women, who visited the department of prosthodontics HP Govt Dental College shimla, OPD for replacement of missing tooth/teeth with a fixed partial prosthesis (FPD). All participants were examined to ensure good oral health except for the symptoms of dentin hypersensitivity. Then clinical and radiographic investigations were performed on all subjects to exclude conditions of teeth, which might have caused pain similar to dentin hypersensitivity. There was at least one vital abutment tooth in each FPD. If an FPD had two vital abutments, only one was chosen, randomly. Each abutment tooth received two stimuli: tactile stimulus and thermal stimulus (water jet at room temperature, 15C and 45C). Sensitive teeth were identified with an explorer passed cervically over the abutment tooth. Ten minutes following tactile stimulation, dentin hypersensitivity was elicited using a jet of water to approximately the same anatomical feature of the tooth as had received the tactile stimulus. Assessment of Sensitivity: Immediately following stimulation, the subjects were asked to grade their overall sensitivity using a 10 cm Visual Analogue Scale (VAS) labelled at the extremes with "no pain," at the zero cm end of the scale, and "severe pain," at the 10 cm end of the scale. Measurements from the scale were made in millimetres giving a scoring range of 0 to 10. Results: Statistically significant results were obtained before (p=0.770) and after tooth preparation (p=0.6420) in both the men and women (Table 2). Comparisons between men and women before and after tooth preparation showed statistically highly significant differences (p=0.001) indicating that women were more sensitive than men bon tactile and thermal stimulation and after tooth. Conclusion: It was observed that women reported more dentin hypersensitivity than men before and after tooth preparation. Key words: Dentin, Hypersensitivity, Survey
