The apparently morphologically normal finding of multiple supernumerary teeth in absence of an associated systemic condition or syndrome is an uncommon phenomenon. Surgical removal of supernumerary teeth is indicated if eruption of the adjacent teeth has been delayed; altered eruption, displacement of adjacent teeth is evident or pathologies such as cystic lesion and resorption of adjacent toot...

The cyst in mixed dentition stage cause expansion of buccal cortex, displacement of teeth and may present as case of infection. The cyst in periradicular region of deciduous molar are of frequent occurrence. The differential diagnosis of this lesion is radicular cysts of deciduous molar: developmental or infammatory dentigerous cyst of corresponding unerupted premolar. After going through the a...

We apply the permanent scatterer (PS) technique to interferometric ERS SAR observations to analyse the surface subsidence induced by hard coal mining activities at the ”Prosper-Haniel” mine (Ruhr region, Germany). Underground mining causes extensive subsidence of serveral meters and typically high subsidence rates at the earth‘s surface. We show that this approach is applicable for the measurem...

Using fast Fourier transform (FFT) analysis, we previously observed that cells within Escherichia coli biofilm are organized in nonrandom or periodic spatial patterns. Here, we developed a gravity displacement assay for examining cell adherence and used it to quantitatively monitor the formation of two distinct forms of cell attachment, temporary and permanent, during early biofilm development....

OBJECTIVE The objectives of the present study were to investigate the prevalence and characteristics of supernumerary teeth and evaluate the associated pathologies and treatment protocol in a Turkish patient population. STUDY DESIGN A retrospective study was performed using full-mouth periapical and panoramic radiographs of 3491 patients (2146 females and 1345 males) ranging in age from 12 to...

PURPOSE Tension band wiring is commonly used for fixation of simple transverse fractures. The popular configuration is parallel Kirschner wires (K-wires) and a stainless steel wire loop placed in a vertically oriented figure-of-8. METHODS We used a wooden model of a patella with a midway transverse fracture and compared four different types of fixation. The first construct had a vertical figu...

Reservoir monitoring improves our understanding of reservoir behaviour and helps achieve more effective reservoirmanagement and prediction of future performancewith obvious economic benefits. It relies on an integrated approach involving both surveillance (well or surface based; seismic, electrical, leakage, flow and deformation measurements, etc.) and modelling. Surface deformation monitoring ...
