title: Dentinal sensitivity among a selected group of young adults in Nigeria.
abstract: BACKGROUND
  There is paucity of data on the prevalence of dentinal sensitivity outside the hospital setting and impact of dentinal sensitivity among young adults in Africa. This study aimed to determine the prevalence and impact of dentinal sensitivity among young adults in Nigeria.
  
  
  METHODS
  A cross-sectional survey was conducted among the undergraduates of University of Benin in August, 2010. Self-administered questionnaire elicited information on demography, self-reported dentinal sensitivity, the trigger factor, action taken, functional, and psychological impact.
  
  
  RESULTS
  The prevalence of dentinal sensitivity was 211 (52.8%) among the participants and it was significantly higher in females than males (P=0.027). Participants experienced shocking sensation more on the left-side of the mouth. The most common trigger factor for the dentinal sensitivity was due to cold drink [169 (80.1%)]. Among the participants with dentinal sensitivity, majority [139 (65.9%)] have not taken any action and only 24 (11.4%) have visited the dentist because of the problem. Dentinal sensitivity exhibited psychological impact among the participants as 64 (30.3) reported unhappiness due to the shocking sensation. Eating and talking were disturbed, respectively, in 59 (28.0%) and 12 (5.7%) of the participants.
  
  
  CONCLUSIONS
  The prevalence of dentinal sensitivity was high which was significantly higher in females than males. Despite the negative functional and psychological impact among the participants, only a few sought dental professional care. Screening for dentinal sensitivity at community level is required to proffer early treatment and ameliorate its impact on the populace.
