Abstract
Information about periodontal disease patterns among the populations of developing countries is limited. These populations may illustrate the natural history of the disease owing to low or virtually no access to dental care, contributing to a more complete understanding of the disease process. The present study aimed to describe the patterns of periodontal loss of attachment (LOA) among representative middle-aged Vietnamese adults. A multi-stage, stratified random sampling technique was employed in two randomly selected provinces. The US NIDR protocol with two sites per tooth for the whole mouth, excluding third molars, was used to assess LOA. A total of 575 subjects aged 35-44 years were interviewed and periodontally examined (response 84.6%). Data were re-weighted to reflect the population of the two provinces. Oral hygiene status was poor with high accumulation of plaque and calculus. The prevalence, extent of sites with pockets (PD), recession (GR) and LOA exceeding various thresholds and the severity of LOA were calculated. Almost all subjects presented with at least one site with LOA > or = 2 mm but the higher levels of the disease were skewed. The extent of sites with GR, PD and LOA > or = 4mm was 1.35, 5.04 and 11.81 per cent respectively. More buccal sites had GR, while more mesial sites had PD and LOA. Severity score of LOA was 2.5 (SD: 0.7). LOA of 4+mm were observed more at maxillary molar buccal sites, followed by mandibular incisor mesial sites. LOA was prevalent among middle-aged Vietnamese adults. The loss of periodontal support was positively skewed and varied between teeth and sites.
