A Principal Component Analysis (PCA) was analyzed for statistical comparison of the mesiodistal
metric measurements of the upper molars of S.

However, in this case a large amount of mesiodistal
movement and tipping was necessary because the crown was very bulbous with an important constricted area at the cement-enamel junction.
For the microtensile test, 5 teeth per group were sequentially sectioned with a water-cooled diamond disc (Isomet 4000) (Buehler, Lake Bluff, IL, USA), along the mesiodistal
and buccolingual axis, in order to obtain beams with a square cross-sectional area of about 1 [mm.
Teeth stored in 1 % chloramine-T obtained from an existing store were examined with an operating microscope (Global Surgical Systems, Saint Louis, MO, USA) (2) and radiographed from a mesiodistal
The largest tooth crown in our sample has a mesiodistal
diameter of 23 mm near the base and carinae with 5 serrations per millimetre.
extension of the cavity on mesial and distal boxes of all prepared teeth was up to 1 mm to adjacent cusp tips (Fig.
They showed that the teeth of patients with oligodontia have smaller mesiodistal
dimensions than in the control group.
If the distance between the brackets is less than 3 mm then forces are delivered in mesiodistal
In a study of 34 pairs of twins, it was shown that the mesiodistal
dimension for all permanent teeth in MZ twins was more concordant than in DZ twins [Kabban et al.
Teeth consist of a rather low, thick crown measuring up to 12 mm in mesiodistal
