Morphological Changes In The Crown Of Mandibular Molars With An Additional
Distolingual Root.
120.280000 microns and lowest marginal gap was at
Distolingual (DL) point C i.e.
An external groove was observed in 41 cases (39.1%)--37 on the mesiolingual side (90.2 %), three on the
distolingual side (7.3%) and one on the lingual side (2.4%).
Meanwhile, PPD and CAL were measured on all six sites of the tooth namely mesiobuccal, midbuccal, distobuccal, mesiolingual, midlingual and
distolingual. All measurements were recorded in the periodontal chart.
Small amounts of wax were placed on the distobuccal and
distolingual line angles of the tooth in order to standardize the location of the tips and the lengths of both retentive arms (premolar: 8 mm; molar: 12 mm) and reciprocating arms.

distolingual root: a case report," Head and Face Medicine, vol.
Pocket depth and clinical attachment level (CAL) were measured for each tooth at 6 sites, namely, mesiobuccal, midbuccal, distobuccal, mesiolingual, midlingual, and
distolingual. Clinical attachment level (CAL) was determined by measuring the distance from the cement enamel junction (CEJ) to the gingival margin with a William's periodontal probe.
Los RMDC mas frecuentes en los dientes premolares fueron el surco vestibular en los primeros y segundos premolares superiores e inferiores (entre 95% y 98%), la cresta central (82% y 80%), surco mesolingual (79%), surco
distolingual (81%).
In 1844, Carabelli first mentioned an extra root on the
distolingual position of permanent mandibular first molar and termed radix entomolaris (RE).
In each subject, 6 sites were evaluated on each tooth present (distobuccal, midbuccal, mesiobuccal,
distolingual, midlingual, and mesiolingual).
The data collection sessions began with a baseline plaque record performed by a calibrated examiner using the O'Leary Plaque Control Record Index, (25-27) to note the presence or absence of plaque on six surfaces of each tooth: mesiolingual,
distolingual, mesiofacial and distofacial.
After the measurement of LD level, probing pocket depth (PPD) and clinical attachment level (CAL) were determined at six sites (mesiobuccal, midbuccal, distobuccal, mesiolingual, midlingual, and
distolingual) on all teeth using a color-coded probe (CP-11 Color-Coded Probe, Hu-Friedy, Chicago, IL, USA) [12].
