Oral pyogenic granuloma, aetiopathogenesis, poor oral hygiene


Background: Oral pyogenic granuloma is a common
oral lesion among African population. It often presents
as a painless, pedunculated, or sessile mass within the
oral cavity. However, etiopathogenesis of oral pyogenic
granuloma is still debatable. This article reviewed and
identified the possible predisposing factors to the
development of oral pyogenic granuloma amongst
patients presenting at a sub urban tertiary health care
Methods: Information about 137 patients that
presented with pyogenic granuloma from January 2009
to December 2019 were retrieved from the records
department of Federal Medical Centre, Nguru. The data
that were reviewed and analyzed included ages of
patients, gender, anatomical site of lesions, treatment
instituted as well as clinical and histopathologic
Results: Patients ages ranged from 10 to 70 years
(mean=41.02± 2.1 years), with the greatest degree of
occurrence (29.19%) in the third decade of life. The
male-to-female ratio was 1:1.7. The most frequently
involved site was the gingiva. Other sites where
pyogenic granuloma was located were the tongue,
check mucosa, and palate. Oral pyogenic granulomas
were more prevalent in the maxilla than in the
mandible, with the labiobuccal gingiva of both jaws
more commonly affected. The main complaint of the
patients was painless swelling associated with
occasional bleeding. More than half of the lesions had a
pedunculated base, with surface ulceration in some
cases. All lesions were surgically excised, although
8.03% of the cases existed as recurrent lesions.
Conclusion: Although the clinicopathologic features of
oral pyogenic granuloma in the study population were
similar to those previously reported and their aetiology
multifactorial, this study revealed that poor oral hygiene
status of patients played a major role in their
