Gingival recession, oral hygiene and associated factors among Tanzanian women.
BACKGROUND
Females are generally more motivated with regard to oral hygiene practices and thus brush their teeth more frequently than males.


OBJECTIVE
To determine the prevalence of gingival recession, oral hygiene status, oral hygiene practices and associated factors in women attending a maternity ward in Tanzania.


METHODS
Cross-sectional descriptive study.


METHODS
Maternity ward of Muhimbili National Hospital, Tanzania.


METHODS
Four hundred and forty six women were interviewed on oral hygiene practices and maternal factors, and a full-mouth examination was done to determine the presence of plaque, calculus, gingival bleeding and gingival recession at six sites per tooth.


RESULTS
The prevalence of gingival recession (GR) > or =1 mm was 33.6%, calculus 99.3%, plaque 100%, and gingival bleeding 100%. Oral hygiene practices included toothbrushing (98.9%), brushing frequency > or =2 times/day (61.2%), horizontal brushing method (98%), and using a plastic toothbrush (97.8%). Factors that were significantly associated with gingival recession were age (OR = 2.0, 95% CI = 1.3-3.2), presence of calculus (OR(a) = 3.8, 95% CI=2.5-7.1), and gingival bleeding on probing (OR = 4.2, 95% CI = 2.5-7.1). Tooth cleaning practices and maternal factors, especially the number of pregnancies or deliveries were not significantly associated with gingival recession.


CONCLUSIONS
In this study population, oral hygiene was poor and gingival recession was associated with age, calculus and gingival inflammation rather than with tooth cleaning practices.
