Abstract/OtherAbstract:
Dentin hypersensitivity (DH) may be present in association with gingival recession. The aim of this study was to determine quantitatively the association of gingival recession and other factors with the presence of DH. One hundred and four Japanese subjects with or without gingival recession were randomly selected. Intact canines and/or first premolars in both maxillary and mandibular quadrants were analyzed. Gingival recession was measured as a vertical length at the buccal site of the teeth. DH was recorded as an ordered categorical variable registering four increasing levels of pain after cold stimulation; from no discomfort to severe pain during and after stimulation (DH1, 2, 3, and 4). Association of DH with periodontal parameters and daily lifestyle was also investigated. Tooth-based analysis of 446 teeth from 104 subjects revealed that DH level was significantly higher in recessive teeth (1, 2, 3, and 4-8 mm) than in non-recessive teeth (0 mm). DH-positive rate in non-recessive teeth was only 18 % (DH1; 14 %, DH2; 3 %, and DH3; 1 %). Highest DH level was observed in teeth with severe recession (4-8 mm), showing DH0; 21 %, DH1; 33 %, DH2; 31 %, and DH3; 15 %. Recession-dependent increase in DH was observed, showing 18, 49, 52, 60, and 79 % DH-positive in teeth with 0, 1, 2, 3, and 4-8 mm recession, respectively. Plaque-free teeth showed a higher DH level than plaque-stained teeth, suggesting that good plaque control may be associated with the presence of DH. There were no significant differences in DH of teeth on the basis of smoking, probing depth, and bleeding on probing. Multiple logistic regression analysis revealed that gingival recession [odds ratio (OR) = 10.2, 95 % confidence interval (CI) = 5.5-18.9] and plaque deposition (OR = 0.3, 95 % CI = 0.2-0.5) were significant contributors to DH. Multilevel modeling analysis revealed that not only gingival recession and plaque deposition but also V-shaped cervical notch and tooth brushing frequency were associated with DH. These results demonstrate that the progression of gingival recession, plaque-free teeth, V-shaped cervical notch, and frequent brushing may be significant predictors of DH in canines and first premolars.
