Abstract
The present study was to investigate the Topography of Root Trunk type (RTT) and Furcation Entrance Dimension (FED) on extracted molars affected with advanced periodontitis and furcation involvement (FI). A total 169 extracted maxillary and mandibular molars (165 patients) affected with severely advanced periodontal destruction. The RTT was categorized as A, B, C, and the FED was clarified into subclass -1, -2, and -3, respectively. Results showed that the prevalence of mandibular second molars with RTT-C and FED-1 occurs higher; (33.0%), and the relationship between RTT and FED is significance (p<0.005). In addition, the relationship between RTT-C and FED-1 also shows a statistical significance (p<0.01) on the buccal surface (41.5%) of the mandibular second molar.
Highlights
It is well-known that some anatomic factors on molar furcation, such as root concavities, Cervical Enamel Projections (CEP), Molar Root Fusion (RF), Intermediate Bifurcational Ridges (IBR), and Shallow Furcation Entrance Dimension (FED) (
Second molar: Molars with Root Trunk type (RTT)-C & FED-3 (30.5%) and RTT-C & FED-1 (21.8%) were the most commonly observed as compared to others (Table 1)
Previous studies indicated that radiographic examination, direct assessment using Bioscan Optimas Image Analyzer (BOIA), [2] digital electric caliper micrometer (DECM) [3] and clinical probing might be the methods of choice to investigate attachment loss of Class III furcation involvement (FI)
Summary
It is well-known that some anatomic factors on molar furcation, such as root concavities, Cervical Enamel Projections (CEP), Molar Root Fusion (RF), Intermediate Bifurcational Ridges (IBR), and Shallow Furcation Entrance Dimension (FED) (
