Background: The number of recurrent tonsillitis and tonsillar hyperplasia requiring tonsillectomies,
annually is huge. Poor oral hygiene has been linked with the occurrence of these tonsillar diseases.
Objective: To determine the association between poor oral hygiene and tonsillitis and/or tonsillar
Methodology: This was a study of association between oral hygiene and tonsillitis and/or tonsillar
enlargement determined by correlating the Oral hygiene index scores (OHIS) and Decay Missing and Filled
Teeth (DMFT) of subjects with complaint of sore throat with development of tonsillitis or tonsillar
hyperplasia. A corresponding number of subjects with no symptoms of sore throat were used as control.
Results: A total of 80 subjects with sore throat were recruited into the study, comprising 49(61.3%) females
and 31(38.7%) males with age ranging from 16 to 32 years. The control group comprised 45(56.3%) females
and 35(43.7%) males with age ranging from 16 to 48 years.. OHIS of the test group was poorer than that of
the control. Erythema (redness) of the tonsil was significantly correlated with OHIS in the test group but not
in the control.
Conclusion: Poor oral hygiene seems to have an association with tonsillar infection and so the,
otolaryngologists managing tonsillar infection should consider inter-disciplinary approach in the
management of tonsillar diseases.
