Background
Retained primary teeth (RPT) are linked with delayed eruption of permanent successors representing a clinically significant finding in children. Radiographic staging helps in an objective approach however local epidemiological data regarding prevalence and contributory factors in Pakistani children remain limited.
Materials and Methods:
It was a retrospective cross-sectional study, conducted at dental OPD and private clinics in Karachi, Pakistan. Panoramic radiographs (OPGs) of children aging from 6–14 years were reviewed consistently. Bivariate analyses and multivariable logistic regression had been performed. Tooth level associations was evaluated using generalized estimating equations (GEE). Statistical significance was set at p < 0.05.
Results
The child-level prevalence of RPT had been estimated approximately 58–62%. Second primary molars in the mandibular were most frequently affected. Multivariable analysis demonstrated that space deficiency and ectopic eruption tendency were independent predictors of RPT.
Conclusion
Retained primary teeth had been found to be linked with delayed eruption are highly prevalent among children in Karachi. Local mechanical factors, particularly space deficiency and infraocclusion, play a significant role. Early radiographic screening may facilitate timely intervention and prevent subsequent orthodontic complications.
