MELO, Thayna Lima de et al. Dentin sensitivity and the impact on the quality of life of patients with chronic periodontitis at the Federal University of Maranhão. Arq. Odontol. [online]. 2015, vol.51, n.4, pp. 179-185. ISSN 1516-0939.

Aim: This study sought to observe the presence of dentin sensitivity in its different degrees and its impact on patients' quality of life. Methods: Thirty-six patients with chronic periodontitis, both male and female, ranging from 18 to 59 years of age, were examined at the Federal University of Maranhão. The patients answered a questionnaire on their socioeconomic status and oral hygiene habits. The impact of dentin sensitivity on the patients' quality of life was assessed by Oral Health Impact Profile-14 (OHIP-14). Clinically, dentin sensitivity was examined by an air-water spray and a #5 dental explorer, using scores 0-3. Data were submitted to statistical analysis by non-parametric chi-square test. The significance level was set at 5%. Results: The results showed that 18 patients presented dentin sensitivity. The premolars were the most affected teeth (55.5%). Dentin sensitivity was most observed when the air-water spray was used (86.1 %), followed by the dental explorer (51 %). The discomfort and mild pain (score 1) was more frequently found when using the air-water spray (43.50%), while severe pain that persists after stimulation was observed in teeth with sensitivity to the dental explorer (51%). The OHIP-14 revealed low (66.67%) and medium (33.33 %) impacts on patients with dentin sensitivity. Patients without dentin sensitivity mostly showed a low impact (94.44%). Conclusion: Dentin sensitivity affected a portion of the periodontal patients, with low to medium impact on one's quality of life.
