Human immunodeficiency virus (HIV) is a pandemic disease affecting all regions across the globe and Nigeria having the second highest prevalence worldwide. Highly active antiretroviral therapy (HAART) has profound negative effect on the optic nerve even though (HAART) has improved the health status of the affected individuals and overall reduction in mortality. Imaging modality especially ultrasound has a great role in the assessment of the optic nerve because of its availability, affordability, and easy operability with reliable sensitivity. ⋯ ONSD values among HIV-positive patients are significantly higher in the left eye and among female subjects. Also, patients with HIV on HAART have thicker optic nerves when compared with general population in Kano, Nigeria.

The aim of this in vitro study was to evaluate the effects of casein phosphopeptides (CPP)-ACPF, NovaMin+ fluoride-containing toothpaste and Xylitol+ fluoride containing cream on demineralized areas on the enamel surface. ⋯ Remineralization was provided in all treated groups, according to the data obtained from all tests. NovaMin was more effective in increasing acid resistance. It was also found that all three experimental groups were effective in increasing the surface hardness, but CPP-ACPF and NovaMin are more effective than Xylitol. However, there was no statistically significant difference between the experimental groups.

Bimaxillary protrusion is a common dentofacial condition associated with proclination of maxillary and mandibular incisors in relation to the dental and cranial bases resulting in soft tissue procumbency. The present retrospective study aimed to investigate dental and soft tissue profile changes using cephalometric analysis to evaluate bimaxillary protrusion patients after extraction of the first four premolars and subsequent retraction of the anterior teeth. ⋯ A statistically significant increase in the nasolabial angle and upper lip length was found in relation to upper and lower incisor retraction and retroclination. A significant reduction was also evident in the post treatment upper incisor exposure, facial convexity angle and mentolabial sulcus depth.

Facial features and personality types vary with different geographical boundaries, culture, and ethnicity. The impression created by teeth design differs with the face and personality of males and females. ⋯ A varying number of combinations are essential in characterizing the face. The personality type has a predominance of one type over other. The interpretation of these combinations in dentistry can help to select appropriate tooth forms and design a harmonious smile.

To compare the shear bond strength of resin cement to zirconia-based monolithic CAD-CAM materials subjected to different surface treatments. ⋯ Monolithic zirconia blocks showed higher bond strength values compared to Y-TZP zirconia block in sandblasting and CoJet groups. HF acid etching is more effective than sandblasting and CoJet for Vita Suprinity.
