Marginal bone loss in the primary dentition

Abstract

The present study was designed to determine the prevalence of bone loss in the primary dentition of children. Radiographs from children aged 7-9 were collected from 25 out of a total of 26 Public Dental Clinics in the County of Orebro, Sweden. These radiographs, representing 36.0%, 50.3% and 48.7% of all 7-, 8- and 9-year-old children (n = 8666) living in the districts of the participating clinics, constituted a primary sample. In addition, the 9-year-olds were subjected to a more comprehensive sampling procedure to obtain a more complete sample (sample of 9-year-olds), resulting in a group of 2017 children (71.9%). The radiographs were evaluated with respect to presence of marginal bone loss (CEJ-MBL: distance between the cemento-enamel junction and the marginal bone level > 2 mm), proximal calculus and number of decayed and filled proximal surfaces (dfsp) in the posterior areas of the primary dentition. In the primary sample, the prevalence of bone loss for > or = 1 proximal surfaces of the primary dentition in the 7-, 8- and 9-year-old children was 2.0%, 3.1% and 4.5%, respectively. The corresponding figures for proximal calculus were 2.5%, 3.1% and 4.2%. Mean number of dfsp amounted to 2.3, 2.5 and 3.0. The prevalences of bone loss and proximal calculus as well as the mean number of dfsp in the sample of 9-year-olds corresponded to the findings for the 9-year-old children in the primary sample.(ABSTRACT TRUNCATED AT 250 WORDS)

Prevalence of alveolar bone loss in healthy children treated at private pediatric dentistry clinics

“…Shapira, et al 26 (1995) found the canines with the greatest CEJ-ABC distance and the second molars the smallest. In studies that evaluate only bitewing radiographs, the primary first molar had the highest BL prevalence 15,27,28 .…”

Evaluation of Gingival Health Status among 6- and 12-years-old Children in Dhamar City, Yemen: A Cross-sectional Study

“…This result suggests that the prevalence of dental calculus increased with the progression of age and this was in agreement with the findings of a previous study. 25 Furthermore, Sjodin and Mattson 26 have reported that the presence of dental calculus in children of 9 years of age was associated with development of periodontitis. Female subjects within the 12 years age group were 0.55 times less likely to have calculus deposits than males within the same age group.…”

Radiographic Assessment of Alveolar Bone Crest Levels in 9-12 Year Old Children in Davangere, India

“…Sjodin and Matsson [22] could not demonstrate any association between age and CEJ-ABC distance in 7-9 years age group and they related this to the narrow age interval of the children in their study. Al Jamal, et al [20] in his study showed that CEJ-ABC distance was not different among the four age groups (6,7,8,9 years) in a study conducted on 539 children.…”

“…Needleman, et al [16] have reported the prevalence of bone loss ranges from 0% to 51.5%. Sjödin and Matsson [6] …”
