To establish a normal range for the radiographic distance between cementoenamel junction and alveolar bone crest and the factors affecting distances for the early assessment of periodontal disease in Dravidian pediatric population.
Fifty children aged 6 to 8 years were selected based on inclusion and exclusion criteria. Clinical and radiographic examination was performed. All the surfaces were examined starting from the distal surface of primary canine to the mesial surface of first permanent molar. The various risk factors like plaque, calculus, proximal caries, restoration and bleeding on probing were recorded. A pair of bitewing radiographs was taken for each child. Bitewing radiographs were traced and analyzed.
It showed that CEJ-ABC distance in primary teeth is about 1 ± 0.5 mm. In the permanent teeth, it was found to be 0.6 ± 0.5 mm in 6 to 8 years age group. CEJ-ABC distance was also affected by different variables like physiologic (eruption and exfoliation) and pathologic factors (plaque, calculus, dental caries, restorations, stainless steel crowns, bleeding on probing and probing depth).
CEJ-ABC distances greater than 2.5 mm should be considered under recall and follow-up. Children and adolescents susceptible to periodontal disease should be identified by radiographic means as early as possible in order to prevent the advance of an otherwise possibly destructive disease. The concept of oral health examination and treatment must include examination of the periodontal status of the patient.
建立德拉威儿童人群中牙骨质釉质界与牙槽嵴之间的影像学距离正常范围以及影响该距离的因素，以便早期评估牙周疾病。
根据纳入和排除标准选取50名6至8岁儿童。进行临床和影像学检查。从乳尖牙远中面至第一恒磨牙近中面检查所有牙面。记录菌斑、牙石、邻面龋、修复体及探诊出血等各种危险因素。为每名儿童拍摄一对咬合翼片。对咬合翼片进行描图和分析。
结果显示乳牙的牙骨质釉质界 - 牙槽嵴距离约为1±0.5毫米。在恒牙中，6至8岁年龄组该距离为0.6±0.5毫米。牙骨质釉质界 - 牙槽嵴距离还受不同变量影响，如生理因素（萌出和脱落）和病理因素（菌斑、牙石、龋齿、修复体、不锈钢冠、探诊出血和探诊深度）。
牙骨质釉质界 - 牙槽嵴距离大于2.5毫米时应进行复查和随访。应尽早通过影像学手段识别易患牙周疾病的儿童和青少年，以防止原本可能具有破坏性的疾病进展。口腔健康检查和治疗的概念必须包括对患者牙周状况的检查。
