Background: The most common periodontal disease in children is gingival inflammation around primary teeth, however, bone loss around the primary teeth has also seen and suggested as a sign of early periodontitis. Therefore it is important to detect the periodontal disease as early as possible in order to prevent the further destruction of tissues.
Aim: To determine the standard value of alveolar bone height.
Materials and Methods: 200 healthy children were joined this study. First group was 4-5 years of age and second group was 9-10 years of age. At least one side of the mandible was free of caries and gingival diseases. Digital radiographs were taken for the anterior and the posterior teeth of that side. Computer software (PlanmecaRomexis Viewer) version 3.8.0. was used for drawing and measuring CEJ-ABC distance on radiograph.
Results: Group 1: The mean CEJ-ABC distance for the primary incisors was (1.06 0.29 mm) and for the primary molars was (0.52 0.13 mm). Group 2: The mean CEJ-ABC distance for the permanent incisors was (0.57 0.09 mm and for the primary molars was (0.80 0.13 mm). The mean CEJ-ABC distance for the first permanent molar was (0.63 0.10 mm). The increased CEJ-ABC distance of either of the incisors in-group 1 or the primary molars in-group 2 compared to their distance in the other age group is significant (P≤0.05).
Conclusion: This study provides valuable information on normal height of alveolar bone in two different age groups.
