Comparative Study
Marginal discrepancy of 3-unit Co-Cr metal copings fabricated with additive and subtractive manners: A comparative study.
Poor marginal adaptation may give rise to a series of biological complications. Despite its importance, comparative studies on marginal adaptation of metal-ceramic fixed restorations fabricated with newer methods are limited. ⋯ SAM group demonstrated superior marginal accuracy. All groups had clinically acceptable marginal discrepancy values (<120 μm), except cast group.

This study was carried out to evaluate the degree of accuracy of age-based weight estimation methods in assessing the weight of the Nigerian child. ⋯ None of the weight estimation formulae assessed was entirely accurate in our study, though the Nelson method showed superior agreement.

: Vascular injuries are commonly seen in both emergency services and forensic medicine practise. They are often life-threatening, with high morbidity and mortality rates. ⋯ The primary goals in extremity vessel injury cases are to prevent mortality, especially after major vascular injuries, and save the extremity from amputation. With a fast, effective and multi-disciplinary approach, an accurate diagnosis and effective surgical intervention can prevent morbidity and mortality as well as reduce the rate of undesirable complications.

To report a comparison of clinical features, visual and anatomic outcomes between patients with retinal detachments from giant retinal tears (GRTs) and those from other types of holes and tears undergoing retina reattachment surgery in the same institution within the same time period in sub-Saharan Africa. ⋯ Good anatomic and visual outcomes can be achieved after surgery for RRD secondary to giant tears in a sub-Saharan Africa setting in this era of small gauge vitrectomy and perflourocarbon use, these outcomes are comparable to those from surgery for RRD secondary to other types of holes and tears.

This study evaluated the effect of oxygen plasma and argon plasma treatments with different application times on tensile bonding of a silicone-based denture liner to polymethylmetacrylate (PMMA). ⋯ This study suggests that the adhesion between PMMA and denture liner is improved under conditions of oxygen plasma treatment with extended exposure time rather than argon plasma treatment.
