This case report presents a rare anomaly observed in an eight-year-old boy of mixed ethnic background. The patient exhibited mandibular left and right permanent first molars, as well as deciduous mandibular first and second primary molars, each possessing three roots. The occurrence of mandibular molars with three roots, known as trifurcation, is relatively uncommon, particularly in deciduous teeth. This case highlights the challenges posed by such anomalies and underscores the importance of early detection and tailored treatment strategies.
