Aim To establish a threshold cemantoenamel junction (CEJ)–alveolar bone crest (ABC) distance in healthy 6‐ to 9‐year‐old Jordanian children and determine the effect of pathological changes, physiological changes, gender, and age on the CEJ–ABC distance. Design Bitewing radiographs were made for 539 6‐ to 9‐year‐old children. Plaque index (PI), gingival index (GI), calculus index (CI), DMFS score, and pocket depth were all assessed through clinical examination. CEJ–ABC distance was measured from radiographs at the mesial surface of permanent first molars (PFM), and the mesial and distal surfaces of primary molars. Results The CEJ–ABC distance ranged from 0.00 to 4.49 mm, the mean for all surfaces was 0.84 ± 0.44 mm, no gender or age group differences were found. The mesial surface of the PFMs had the smallest mean CEJ–ABC distance. The CEJ–ABC distances were greater in the maxilla than in the mandible. No significant effect of PI, GI or CI on CEJ–ABC distance was found. Caries, faulty restorations, exfoliation, and partial eruption adjacent to measured surfaces had significant effect on the CEJ–ABC distance. Conclusion The mean CEJ–ABC distance was <1 mm. Threshold CEJ–ABC distances of 1.0 and 1.5 mm for PFMs and primary molars, respectively, are suggested to be used in 6‐ to 9‐year‐old children.
