In Papua New Guinea the main dental problem has been periodontal disease and related conditions. Dental caries appears to be low in many community groups. The aim of this study was to explore the prevalence of dental caries and the periodontal health status of teenage schoolchildren in Port Moresby. 200 children of mean age 15.4 years were examined from two urban community high schools in Port Moresby. 44% of the children examined were caries-free and the average decayed, missing or filled teeth (DMFT) score was 1.43, while only 2.5% of the children had totally healthy periodontal tissues. 18% of them showed pathological periodontal pockets of 4 or 5mm in depth, the remaining children having either gingival bleeding, calculus or both. The results indicated that this group of children showed a low prevalence of dental caries and a high prevalence of periodontal problems. No cases with deep periodontal pockets of 6mm or more were found.

Often referred to as 'the last unknown', Papua New Guinea's largely unexplored environments across its four distinct regions, the Highlands, New Guinea Islands, Momase, and Southern, exhibit remarkable diversity. Understanding this diversity is significant in contextualising the risk factors associated with developing non-communicable diseases. This review aims to map and summarise the literature to provide region-specific prevalence data for risk factors and non-communicable diseases.

The global strategy to #EndAIDS is underpinned by a call to end all inequities and to ensure no-one is left behind; but inequities continue, and people are still being left behind. Despite the advances seen in some populations and in some geographical areas, with ongoing high rates of HIV vertical transmission, ending HIV for pregnant and breastfeeding women and their children must be prioritised urgently. Focused on Asia and the Pacific, the region with the second largest number of people with HIV, in this viewpoint we highlight the heterogenous nature of global and regional success in eliminating vertical transmission of HIV.
