The canal outlines for the mesiobuccal and distobuccal roots were quite clear and traceable till the apex [Figure 1a]. An ultrasonic tapered and active tip Start-X  #3 (Dentsply Maillefer) [Figure 1b] was introduced to remove the calcific obstruction. The calcified mass thus removed, had its extension into the palatal root canal that traversed along its entire length [Figure 1c]. The length of calcified tissue was measured to be 16 mm long [Figure 1d]. Morita, Kyoto, Japan) apex locator for all the three root canals and confirmed by a radiograph [Figure 1e]. Post-obturation radiograph was taken which showed well-obturated root canals [Figure 1f]. The patient was asymptomatic during follow-up after 6 months [Figure 1g] and was advised to get this tooth crowned. The calcified mass thus removed was preserved in 10% neutral buffered formalin and was embedded in paraffin wax for the histopathological evaluation [Figure 1h]. These calcified masses varied in their size and were scattered throughout the substance of pulp, they resembled dystrophic calcification [Figure 1i].
