abstract ={Background: Crown discoloration is one of the complications associated with traumatic dental injuries. It is the external expression of changes in the pulp- dentine complex that becomes visible through the translucent enamel. It is a sign of internal damage, but not necessarily irreparable damage.
Objective: To determine the prevalence of crown discoloration following traumatic dental issues and possible factors associated with crown discoloration. 
Methods: A prospective cross-sectional study of patients with traumatic dental injuries. The crowns of all anterior teeth were examined for signs of trauma. Visual colour determination was done using visual comparison of the traumatized tooth crown red with the contralateral tooth if unaffected or adjacent unaffected tooth. Tooth crown colour was classified as normal or discoloured. Data was subjected to descriptive analysis in the form of frequencies, percentages, mean, standard deviation and cross tabulations. Chi square was used to determine association between variables with p set at 0.05. Logistic regression was used to identify significant predictors of tooth discoloration following traumatic dental injury.
Results: A total of 161 participants were recruited for this study. The prevalence of discoloured traumatised teeth was 33.5%.  There was statistically significant association between level of education and presenting with a discoloured traumatised tooth. The higher the age of the participant the less the likelihood of having traumatised teeth that became discoloured. The odds for a female participant to have traumatised teeth that became discoloured was 2.642 times higher than the odds for a male and this was significant (p=0.03). the odds for a semi-skilled worker to have traumatised teeth that became discoloured was 3.759 higher than the odds for a professional and this was statistically significant (p=0.03). 
Conclusion: Crown discoloration is a significant sequela of traumatic dental injury. Level of education is associated with presenting with a discoloured traumatised tooth. Gender, age and level of education are predictors of patients presenting with discoloured traumatised teeth.
