Endodontic microsurgery is a highly predictable treatment option in most cases when conventional endodontic treatment is not feasible. Nevertheless, mandibular molars are still considered by clinicians to be the most difficult type of teeth, with the lowest success rate. In recent years, endodontic microsurgery has been attempted more frequently with the emergence of modern cutting-edge technologies such as dental operating microscopes, various microsurgical instruments, and biocompatible materials, and the success rate is increasing. This review describes the current state of the art in endodontic microsurgical techniques and concepts for mandibular molars. Notably, this review highlights contemporary equipment, technology, and materials.

Abstract In this study, the wicking properties of ring and compact-siro ring spun staple yarns were compared. The twist level, which is related to the structure of the staple yarns, was found to significantly influence the wicking property of the two kinds of yarn. Polyester staple fibers with 1.33 dtex × 38 mm were selected as the staple fiber material, and the effect of the twist level on the wicking property was investigated using the capillary rise method. The results show that with a decreasing twist coefficient, the wicking height increases with a decrease in yarn compactness. The compact-siro spun yarn showed better wicking properties owing to it special ply yarn structure. Furthermore, the tension property of the yarns decreased significantly with a decrease in the twist coefficient. Compact-siro spinning was carried out to obtain staple yarns with lower twist coefficients, and the yarns showed great improvement in terms of yarn strength, fiber straightness, and wicking properties. Thus, compact-siro spinning is an efficient method to improve the wicking properties of staple yarns.

Spinning Process

The two component filament/staple fiber core-spun yarn is spun on FA506 ring spinning frame with PTT filament as interlaced yarn and Tencel staple fiber as outer sheath. The spinning process and process parameters were analyzed. The morphology, mechanical property and wear-resisting property of two component core-spun yarn were tested. Results indicate that elastic recovery rate of core-spun is up to 90.6%; broken strength is up to 20 cN/tex after boiling water treatment. The core-spun yarn can be used as a new kind of knitting yarn for sweater.

Before And After

An assessment is made of irregularities added in apron drafting through comparisons of variance-length curves of fiber end density before and after drafting. In addition, the drafted products were examined for periodicities through correlograms. The investigations were made on a carded and a combed cotton and a cut staple fiber for a range of drafts. The studies were later extended to obtain relations of thickness irregularity with draft and hank of material fed. The implications of these results are discussed. Further, the effect of apron opening and doubling on yarn quality and a critical comparison of roller and apron drafting in regard to extent of irregularities added are presented.
