extrusive

Among the types of injury, enamel infractions accounted for 9%, enamel fractures for 19%, enamel-dentin fractures for 38%, complicated crown fractures for 16%, root fractures 3%, concussion 1%, subluxation 3%, extrusive luxation 3%, lateral luxation 4%, and avulsion for 4% of the injuries.

With light extrusive forces, periodontium follows the tooth movement, which is desirable when there is an uneven gingival margin between the adjacent teeth (6).

In that study, no significant differences were found in LDF signal levels between controls and 16 out of 20 traumatized teeth (unresponsive to EPT); however, given that the study population included only subluxation injuries, which are less severe than extrusive injuries, these findings are not particularly surprising.7 The present study's finding that PBF gradually recovered to a point where there were no longer any significant differences in PBF values of traumatized teeth and controls is in line with a previous LDF study by Gazelius B et al.6 That study reported PBF of subluxated teeth to be arrested at one week, partially restored at six weeks and to regain normal values at 9 months post-trauma.

The studied rock is an extrusive porphyritic igneous rock called rhyodacite tuff.

Meanwhile, curves of approach temperature exhibit extrusive relations with flow rate of water, or quite opposite demeanor to the trend of range and efficiency curves, and also the linearity is a clear feature of the curves.

2002), suggesting that they may be the extrusive equivalents of the peralkaline Welsford, Jake Lee Mountain, and Parks Brook granites.

The trauma records were assessed as injuries to hard dental tissues and the pulp (enamel infraction, enamel fracture, enamel-dentin fracture, complicated crown fracture, uncomplicated crown-root fracture, complicated crown-root fracture, root fracture) and periodontal (concussion, subluxation, extrusive luxation, lateral luxation, intrusive luxation, avulsion) according to the criteria of World Health Organization and was modified by Andreasen and Andreasen (17).

Hence, even less force applied may produce greater pressure in the periodontal ligament and thus increases the extrusive component of the applied force.

Furthermore, this avoids intrusive forces on the anchor molar (and extrusive ones on the side to be expanded) during the correction of the crossbite.

A prominent topography characteristic within the Dabashan area is a southwestward extrusive arc (Bashan Arc fault) that is one of key factors to understand the geodynamic condition of the Dabashan thrust nappe structure.

TDI was classified as enamel fracture, enamel + dentin fracture, complicated crown fracture, extrusive luxation, lateral luxation, intrusive luxation and avulsion (26).

We have compared the CSD pattern of the plagioclase of Zanbil dacites with other well studied extrusive and intrusive igneous rocks plagioclase CSDs (Fig.

(2007) proposed an extrusive dome formed by viscose magma.
