Longevity of Amalgam Build-Up Restorations in Endodontically Treated Teeth

Background and Aim: Restoration of endodontically treated teeth is one of the most important and challenging topics in restorative dentistry. Longevity of such restorations is an essential factor in treatment planning. Amalgam build-up is a conservative method for restoration of endodontically treated teeth. Therefore, this study aimed to assess the longevity of this type of restoration in endo...

Measurements of output factors using different ionization chambers and build up caps

Background: The aim of this work was to study the output factors for Linac using different ionization chambers and build up caps. Materials and Methods: Output factors were measured for open square fields (3 × 3 cm to 40 × 40 cm) defined by collimator jaws for 6 and 15 MV photon beams from a Varian Clinac 2100C accelerator were measured. The measurements in air were performed using Com...

Photoelectron Flux Build-Up in the Plasmasphere

How to build up the perfect tooth.

The appearance of the upper anterior teeth in the preoperative situation was unsatisfactory. Tooth 11 looked particularly unattractive. Neither its shape nor its shade satisfied the standards of a high-quality dental restoration. In order to obtain a clearer picture of the preoperative situation, a greyscale image was produced (Figure 1). This image illustrates the insufficient brilliancy as we...

Modelling apical build-up of auxin

The simplest way of adapting the 6-channel model (Fig 6) to model the data of Brewer et al. [1] is to introduce weak, saturable coupling between the channels, as shown in S6A Fig. The retarding of the 26.5 ng pulse seen in this model can be interpreted as follows: As the uptake increases, and hence the intracellular auxin concentrations rise, saturation makes the lateral permeability effectivel...
