Relations between dental plaque, gingivitis and dental caries among 21-50 years dental patients

Abstract EN

Background : The reason for this study was to find the relation between dental plaque, gingivitis and dental caries.

Materials and methods : The study was conducted among 52 patients attending department of Periodontics, college of dentistry, Arbil, age (21-50) years grouped into 3 age groups.

The plaque index (PI), gingival index (GI), calculus index simplified (Cal-SI) and dental caries from the DMFS were used.

Results : Positive correlation between PI and GI (r = 0.48) & weak positive correlation between PI and Cal-SI (r = 0.33).

But negative correlation was found between PI and DMFS (r = -0.059).

No significant differences were found for each of plaque, calculus and gingival indices between different age groups (P > 0.05).

The study showed higher mean number of DMFS in the age group (31-40) years with no significant differences between age groups and gender.

Conclusion : Gingivitis is plaque associated disease but dental caries is not.
