Odontogenic Tumours: A Clinicopathologic Appraisal of Cases seen in a Nigerian Tertiary Hospital using 2017 WHO Classification.

Background: Odontogenic tumours (OT) are a group of diverse lesions seen in the maxillofacial region. They are categorized according to their tissues of origin as; epithelial, mesenchymal or mixed tumours.

Objectives: The aim of this study is to present the proportion of odontogenic tumours seen in Lagos University Teaching Hospital using the 2017 WHO classification.

Transfection Efficacy and Cellular Uptake of Lipid-Modified Polyethyleneimine Derivatives for Anionic Nanoparticles as Gene Delivery Vectors.

Cationic polyethylenimine (PEI)-based nonviral gene carriers have been desirable to overcome the limitations of viral vectors in gene therapy. A range of PEI derivatives were designed, synthesized, and evaluated for nonviral delivery applications of plasmid DNA (pDNA). Linolenic acid, lauric acid, and oleic acid were covalently conjugated with low-molecular-weight PEI ( ∼ 1200 Da) via two different linkers, gallic acid (GA) and -hydroxybenzoic acid (PHPA), that allows a differential loading of lipids per modified amine (3 vs 1, respectively).

An evidence-based surgical algorithm for management of odontogenic keratocyst.

The effective management of odontogenic keratocyst (OKC) remains a subject of interest and confusion in the oral and maxillofacial surgery literature. Currently, there is a lack of consensus regarding the most appropriate treatment for patients with OKC. Of the various treatment options available, no modality to date has been shown to demonstrate a zero or near-zero recurrence rates except wide resection with clear margins.

Mercury hygiene and biomedical waste management practices among dental health-care personnel in public hospitals in Lagos State, Nigeria.

Background: Indiscriminate disposal of hospital wastes including mercury/amalgam wastes pose a serious threat to life and environment. There is a growing concern about biomedical waste (BMW) management among health care workers, however there are limited reports on BMW management by dental personnel in developing countries.

Objectives: This study investigated the level of knowledge of BMW, observance of proper mercury hygiene and BMW management practice among public dental personnel in Lagos State, Nigeria.

Plunging ranula: surgical management of case series and the literature review.

Plunging ranulas are rare; report of this condition is particularly limited in our environment. We present case series in children; with all cases having both oral and cervical components. It is important to note this type of presentation of plunging ranula and their appropriate management.
