The aim of this study was to compare the pulpal reactions after exposure due to trauma and/or caries and to suggest the appropriate treatment options for the management of pulp, in the light of the histological findings in the primary teeth. Fifteen primary maxillary incisors with pulpal exposure were examined with light microscope in a blind study. After the histological evaluation, teeth were divided into three groups for the etiological factors due to the exposure according to the patient's files: trauma group, caries group and caries and trauma group. The inflammatory infiltration was diminished from the pulp chamber towards the apical third of the root canal in all of the examined teeth. Teeth in the trauma group presented fewer inflammatory cells in the root canal in comparison with other groups. It was concluded that the teeth with traumatic pulp exposure were considered as more likely to respond positively to pulpotomy technique. Pulpectomy or extraction seemed to be indicated for the decayed or decayed and traumatically injured teeth.
本研究的目的是比较因外伤和/或龋齿导致牙髓暴露后的牙髓反应，并根据乳牙的组织学结果，为牙髓管理提出合适的治疗方案。在一项盲法研究中，用光学显微镜检查了15颗上颌乳切牙牙髓暴露的情况。经过组织学评估后，根据患者病历中牙髓暴露的病因将牙齿分为三组：外伤组、龋齿组和龋齿合并外伤组。在所有检查的牙齿中，炎症浸润从牙髓腔向根管根尖三分之一处逐渐减少。与其他组相比，外伤组牙齿根管内的炎症细胞较少。得出的结论是，外伤性牙髓暴露的牙齿似乎更有可能对牙髓切断术产生积极反应。对于龋坏或龋坏合并外伤的牙齿，似乎需要进行牙髓摘除术或拔牙。
