ABSTRACT


Aim

The accessory canals in the furcation of primary molars can explain the frequent presence of radiolucency in
the furcation area in case of pulpitis and necrosis of teeth. In fact these canals can represent a communication between
periodontium and pulp tissue allowing bacteria to enter. The aim of this study was to determine the prevalence of foramina in
the furcation area of primary molars.

Methods

The presence of foramina was assessed using extracted
deciduous molars examined with Scanning Electron Microscope (SEM) evaluation. Thirty extracted human primary molars
(15 upper deciduous molars and 15 lower deciduous molars) were selected to evaluate the presence of extra foramina in their
furcation. All teeth were prepared according to Koenigs' technique: the roots were cut in the furcation area perpendicular to
the canals (1.5 mm apical to the external surface of the furcation and 1 mm apical to the cervical line) and then analysed with
an electronic scanning microscope. RESULTS AND

Conclusion

This study demonstrated that 23 teeth (77 of the
samples) had one or more extra foramina near the furcation.
