This retrospective study aimed to (i) survey the correlation between decayed, missing, filled teeth (DMFT), and presence of first permanent molars (FPMs) with poor prognosis and (ii) evaluate the treatment requirements.
Seven hundred seventy-three children with fully erupted FPMs were included in this study. DMFT for the permanent dentition, FPMs, and Global DMFT were evaluated based on clinical and radiographic evaluation. The ratio of deep dentin caries (DDC) and apical lesion presence among FPMs, including treatment requirements, were analysed. Spearman rank correlation coefficient and t tests were used for statistical analysis.
The caries prevalence was found at 61.4%, where the mean DMFT was calculated as 1.89 ± 2.15. There was a positive correlation between DMFT values and age (r = 0.27). On the other hand, there was a negative correlation between global DMFT values and age (r = - 0.29). Regarding treatment needs of FPM with poor prognosis, 12.03% of the teeth needed pulpectomy, 8.93% pulpotomy, 8.93% pulp capping, and 5.3% extraction. Having higher DMFT values was correlated significantly (p < 0.01) with the presence of DDC (r = 0.50) and apical lesion (r = 0.34). Susceptibility to DDC and apical lesions was significantly higher at mandible than maxilla (p < 0.01). The correlation was significant between DMFT values and apical lesion presence (p < 0.01).
The ratio of FPMs with poor prognosis was found high in the study group. Treatment requirements of FPMs increased with age, and pulp interventions often took part in the majority. This study successfully concluded that higher DMFT values were correlated with the presence of DDC and apical lesion.
FPMs with poor prognosis demonstrate a risk factor for apical lesion presence.
本回顾性研究旨在：(i) 调查患龋状况（DMFT）和第一恒磨牙（FPM）缺失与预后不良的相关性；(ii) 评估治疗需求。
本研究纳入 773 名 FPM 完全萌出的儿童。通过临床和影像学评估，评估恒牙 DMFT、FPM 和全球 DMFT。分析 FPM 深龋（DDC）和根尖病变的比例，包括治疗需求。采用 Spearman 秩相关系数和 t 检验进行统计学分析。
龋齿患病率为 61.4%，平均 DMFT 为 1.89±2.15。DMFT 值与年龄呈正相关（r=0.27），而全球 DMFT 值与年龄呈负相关（r=-0.29）。在预后不良的 FPM 治疗需求方面，12.03%的牙齿需要牙髓切除术，8.93%需要牙髓切断术，8.93%需要牙髓盖髓术，5.3%需要拔牙。较高的 DMFT 值与 DDC（r=0.50）和根尖病变（r=0.34）的存在显著相关（p<0.01）。下颌的 DDC 和根尖病变易感性明显高于上颌（p<0.01）。DMFT 值与根尖病变的存在显著相关（p<0.01）。
研究组中预后不良的 FPM 比例较高。FPM 的治疗需求随年龄增长而增加，牙髓干预往往占大多数。本研究成功表明，较高的 DMFT 值与 DDC 和根尖病变的存在相关。
预后不良的 FPM 存在根尖病变的风险因素。
