The prevalence of functional low vision in southeast Nigeria is reportedly the highest in the country. ⋯ Low vision services are available in some tertiary facilities in southeast Nigeria. Improved funding and better awareness of the availability of low vision services by eye care providers and the general public are needed to strengthen services.

During post restoration, different root structures require several types of posts to increase duration of their clinical use. Several materials have been investigated to enhance their quality and optimize their length according to the available root canal. ⋯ Current experiments supported that 6-mm post size can increase the bonding between root canal dentin and studied posts. When considering post materials, fiber provided the best bonding strength in current laboratory setup. Second, zirconia had meaningfully acceptable bonding strength; however, the bonding strength of ceromer posts was not favorable. Further studies optimizing post fabrication techniques of root materials may increase the bonding strength of posts to human dentin to an acceptable clinical degree.

The aims of this study were to evaluate the surface morphology and surface roughness of restorative materials containing glass ionomer, analyze Streptococcus mutans biofilm formation on the surface of materials, and determine the correlation between surface roughness and biofilm. ⋯ The resin content and small filler particle size of material positively affect surface roughness. However, there is no direct relationship between surface roughness and biofilm.

When teeth have responded poorly to conventional endodontic treatment or when they cannot be treated adequately by nonsurgical means, surgical endodontics remains the treatment of choice. Healing of apical lesions occurs by repair, most of the time. "Repair is the healing of a wound by tissue that does not fully restore the architecture or function of the affected unit". Since this is not ideal, newer regenerative procedures that aim to restore lost tissue have been introduced. β -Tricalcium phosphate is an alloplastic bone graft material that forms a scaffold for closing the bony defect. ⋯ Platelet-rich plasma (PRP) and platelet-rich fibrin (PRF) are platelet concentrates, rich in growth factors and they promote regeneration by osteoinduction. This article describes cases of bone augmentation with a combination of PRP + β -TCP and PRF + β -TCP for treatment of the chronic periapical lesion. The cases were followed for six months and one year and healing was evaluated quantitatively using cone beam computed tomography.

To determine the emigration plans after graduation of clinical medical students of Ebonyi State University Abakaliki, Nigeria. ⋯ Majority of students intend to pursue specialist training and prefer training abroad. Minor proportions were willing to specialize in Nigeria and serve in rural areas. The students may have perceived medical practice in Nigeria as serving in rural areas hence students willing to work in rural areas were more likely to specialize in Nigeria. This may adversely affect health service delivery in Nigeria if left unchecked. Nigerian authorities should ensure that medical graduates willing to practice in Nigeria are not deterred. Also, plans to encourage doctors to practice in Nigeria should receive desired attention.
