Periodontal status of 14–16‐year‐old Danish schoolchildren

Abstract

– The purpose of this study was to determine the prevalence of periodontal disease in teenagers. The survey was conducted on 325 children aged 14,15 and 16 years, living in Aarhus, Denmark. Pocket depth and loss of attachment were measured in mm at the maxillary and mandibular first molars and incisors. Plaque, calculus and gingival bleeding on probing were recorded. A total of 221 children (68%) had 4–5 mm deep pockets and 19 children (5.8%) had pockets deeper than 5 mm on at least one tooth Approximately 11% of the subjects showed loss of attachment on at least on tooth. The frequency of surfaces with plaque and gingivitis was high in all three age groups. Plaque, gingivitis, deepened pockets and loss of attachment were most frequently observed on interproximal surfaces. No significant differences were observed between the sexes with regard to periodontal disease.

Radiographic parameters: biological significance and clinical use

“…In young adults, a wide range in the prevalence of sites with a distance > 2 mm from the cementoenamel junction to the alveolar crest has been reported (1–89%) (80). The large variations in radiographic results among studies may be due to methodologic problems, but also to differences in the race of study subjects, their disease susceptibility and access and use of preventive care (1, 2, 5, 11, 17, 40, 52, 59, 66, 67, 81, 82, 155). Adolescents not performing oral preventive measures showed more loss of crestal alveolar bone than adolescents enrolled in a preventive care program (80).…”

“…Studies evaluating initial crestal alveolar bone loss have proposed different thresholds to distinguish between disease and no disease: > 1 mm (71, 90, 95), > 1.5 mm (34), > 2 mm (66, 67, 86) or > 3 mm (18, 88). The choice of cutoff values affects the diagnostic sensitivity and specificity in detecting alveolar bone loss.…”

Periodontal Treatment Needs and Prevalence of Localized Aggressive Periodontitis in a Young Turkish Population

“…There is great variability among studies conducted in different countries. In Western European countries, in which white populations were examined, the prevalence was between 0.1% and 0.2% 7,15,16,19,20 . The prevalence was reported to be 0.1% in England, 21 0.6% in The Netherlands, 22 and 0.3% to 2.4% in various parts of the United States, 2,8,23‐25 where the study populations were of mixed ethnic origins.…”

“…Variations in the gender ratio have also been attributed to age differences in the study populations 15 . In general, more recent epidemiologic studies 5,8,15,16 of random samples with well‐defined diagnostic criteria did not confirm a higher prevalence in females. Saxby 10 suggested that the gender ratio for the disease might be more balanced than previously supposed.…”

A longitudinal study of dental health and treatment need in Swedish teenagers

“…In addition, there have been some cross-sectional studies in which caries prevalence has been recorded at 5-to 10-yr intervals (2)(3)(4)(5), As most of these epidemiologic studies have concentrated on dental caries, knowledge of a corresponding improvement in periodontal health is much scarcer. Recently, however, prevalence studies of gingival and periodontal status have been published (6)(7)(8)(9)(10)(11).…”
