Restoration of crown-root fractures with the involvement supracrestal attached tissues represents difficulties for clinicians, as these types require a multidisciplinary approach adequate treatment and successful prognosis. Depending on location fracture, different approaches, such periodontal crown lengthening procedures, rapid orthodontic or surgical root extrusion tooth extraction followed b...

Among measures that are used to prevent the triggering of shallow landslides and for erosion control, root reinforcement has spread out widely as its contribution environmental sustainability is high. Although in recent years reliability-based design (RBD) been applied increasingly assessment slope stability address shortcomings deterministic approach (which does not consider geotechnical uncer...

OBJECTIVES The aim of this study was to compare in vitro root fracture resistance following root canal filling with AH 26 using lateral condensation, BeeFill, and Thermafil techniques. STUDY DESIGN Eighty extracted human mandibular premolars with similar dimensions were selected. In order to standardize the roots, measurements were taken in two separate regions of the teeth--at the cemento-en...

Root–soil mechanical interactions are of vital importance in soil reinforcement by plant roots. However, it is unclear how the angles roots affect root–soil interactions. To better understand effect this factor on interactions, pullout tests were conducted alfalfa (Medicago sativa L.) with five root diameter groups (0.10–0.30 mm, 0.31–0.50 0.51–0.70 0.71–0.90 mm and 0.91–1.10 mm) four embedding...

in this study the performance of clay nano-particles on the soil reinforced with polypropylene fibers (pp-fiber) has been investigated. also a series of investigations concerning the effect of random orientation of fibers on the engineering behaviour of soil were conducted. soil mixtures were modified with varying percentages of nanoclay and fibers. unconfined compressive strength (ucs), compac...

• A new analytical model for the mobilization of root reinforcement is developed. 3-D orientations, slippage and non-linear behaviour are incorporated. The matches magnitude gradual observed in experiments. effect key parameters driving can now be quantified. Roots stabilise slopes against shallow landslides by mobilising their mechanical strength. Existing models highly simplified typically fo...
