Assessment of Self-Perceived Halitosis and Oral Hygiene Habits Among Dental Students in Ernakulam District

Aim: The aim of this study was to evaluate the self-perception of oral malodour and oral hygiene habits among dental students in Ernakulam district of Kerala. Materials and Methods: A structured and validated questionnaire comprising of ten questions was distributed to 787 students of five dental colleges in the Ernakulam district of Kerala. The questionnaire evaluated the self-perception of halitosis, the oral hygiene practices among them and the presence of gingival bleeding, dental caries and dryness of mouth. Results: The dental students here included 678 females and 109 males. Self-perceived halitosis was reported by 46(42.2%) male students and 221(32.6%) female students showing a statistically significant difference (p<0.05) between both genders in reporting self-perceived halitosis. Conclusion: The results reveal a higher prevalence of self-perceived halitosis among males compared to females in this sample. The knowledge about halitosis and related factors was also greater among this sample of dental students. Clinical significance: The findings of our study highlight the fact that the regular removal of tongue coating and use of interdental aids along with regular oral hygiene measures can significantly reduce halitosis in an otherwise healthy individual.
