Abstract
Dental traumas are highly prevalent lesions in primary teeth, but crown root fractures are rare. Mostly anterior tooth segment is more commonly involved. Posterior crown root fractures are very rare. A 4-year-old girl reported to our paediatric dentistry department with a 10-day history of severe pain and discomfort in both right and left posterior teeth region. The child was suffering from severe and continuous pain and was unable to chew food. After an examination a fracture was noticed in intraoral periapical radiograph and treatment plan was decided to preserve the affected teeth.
摘要
牙外伤在乳牙中是非常常见的损伤，但冠根折却很罕见。大多数情况下，前牙段更常受累。后牙冠根折非常罕见。一名4岁女童因左右后牙区严重疼痛和不适10天前来我院儿童牙科就诊。患儿遭受着剧烈且持续的疼痛，无法咀嚼食物。经检查，口腔根尖片显示有骨折，遂决定制定治疗方案以保留患牙。
