The midline diastema is a space (or gap) between the maxillary central incisors . The space can be a normal growth characteristic during the primary and mixed dentition and generally is closed by the time the maxillary canines erupt. Researchers and clinicians now believe that multiple factors may contribute to a midline space including abnormal frenum, midline bony clefts ,oral habits, soft ti...

INTRODUCTION Among all prognostic factors, "margin status" is the only factor under clinician's control. Current guidelines describe histopathologic margin of >5 mm as "clear margin" and 1-5 mm as "close margin." Ambiguous description of positive margin in the published data resulted in comparison of microscopically "involved margin" and "close margin" together with "clear margin" in many publi...

This paper examines optimal redistribution in a model with high and low-skilled individuals with heterogeneous tastes for labor, that either work or not. With such double heterogeneity, traditional Welfarist criteria including Utilitarianism fail to take the compensation-responsibility trade-off into account. As a response, several other criteria have been proposed in the literature. This paper...

Invasive cervical root resorption is a relatively uncommon form of external root resorption. Creeping attachment is defined as postoperative coronal migration of the gingival margin. We describe a case of invasive cervical root resorption following coronal shift of interdental papillae 15 years after modified Widman flap surgery.

The work presented here addresses the issue of tuning PD controllers for controlling integrating plus deadtime (IPDT) processes using settling time and gain and phase margin specifications. Tuning formulae are derived for PD controller being used for controlling IPDT processes. Simulations have been carried out to determine the effectiveness of the tuning formulae. Also, comparison between prop...

This paper investigate the results of distributing the delay of a single feedback system. To distribute the delayed feedback, the single delay is replaced by the sum of two distinct delays with the same e↵ective delay. The statistical properties of the new distribution function in the feedback, namely the sum of two delta functions, are used to quantify the e↵ectiveness of delay distribution. W...
