Abstract
Aim: The aim of the present study was to investigate
reasons for permanent tooth extraction at the Lagos
University Teaching Hospital, Lagos, and compare this with
a study done 16 years previously in the same institution,
with a view to evaluating trends in reasons for tooth
extractions in the studied environment.
Methods: A retrospective review of patients who had nonsurgical
extraction of their teeth at the Lagos University
Teaching Hospital, Nigeria between January and
December, 2006 was carried out. The following data were
retrieved: Age and sex of patients, reason for the extraction
and types of tooth removed. The data obtained was
compared with similar study done 16 years previously in
the same institution.
Results: Caries and its sequelae and periodontal diseases
were the main reasons for tooth extraction in both study
periods. Caries and its sequelae as a reason for dental
extraction in the second period increased by a factor of 1.2
in comparison with the first period, whereas periodontal
disease as a reason extraction in the second period
decreased by a factor of 2.7. In addition, orthodontic
reasons and tooth impaction as a reason for dental
extraction increased by a factor of 4 and 1.3 in the second
period respectively. In both study periods, most extractions
were carried out in patients within age group 11-40 years
(1990,77%; 2006, 62.3%). Teeth most frequently extracted
were posterior teeth (1990, 89.2%; 2006, 89.4%).
Conclusions: Dental caries and its sequelae, and
periodontal disease despite being preventable diseases,
still remain the two most common reasons for dental
extraction in our environment. Therefore,efforts must be
made to improve the dental health awareness and status
of Nigerian populace to reduce the morbidity associated
with the two preventable causes of tooth loss.
