Biological and chronological age of dental eruption and its relation to nutritional status in pediatric patients in the dental clinic Dr. René Puig Bentz of the Pedro Henríquez Ureña National University.

The nutritional status of pediatric patients is critical to their growth and development. Assessment includes anthropometry (weight, height and BMI), biochemical analysis, dietary assessment and clinical examination. The most common problems are malnutrition, overweight, obesity and micronutrient deficiencies, such as iron and vitamin D. The main objective of this study was to determine the correlation between biological age and dental eruption chronology and nutritional status in pediatric patients newly admitted to the Dr. René Puig Bentz Dental Clinic. A population of 65 patients aged between five and ten years was studied. The children were weighed, their height measured to determine their BMI and nutritional status, and their panoramic radiographs evaluated to estimate their biological age using the Nolla method. The results showed that, in terms of biological age, the most common age was seven years (29.08%) and the least common age was ten years (4.62%); the most common chronological age was eight years (24.62%). It was also observed that the sex with the earliest tooth eruption was female (13.85%). Finally, there was a predominance of accelerated eruption in underweight children (6.15%), a predominance of delayed eruption in healthy weight children (21.54%) and a predominance of accelerated eruption in obese children (9.23%). In overweight children there was a predominance of delayed eruption (7.69%) and in obese children there was a predominance of accelerated eruption (7.69%).

儿科患者的营养状况对其生长发育至关重要。评估内容包括人体测量学（anthropometry）（体重、身高及BMI）、生化分析、膳食评估及临床检查。最常见的问题包括营养不良、超重、肥胖及微量营养素缺乏（如铁和维生素D缺乏）。本研究的主要目的是确定新入院于Dr. René Puig Bentz牙科诊所的儿科患者中，生物年龄、牙齿萌出时序与营养状况之间的相关性。研究纳入了65名年龄在5至10岁之间的患者。研究人员对儿童进行了体重测量、身高测量以计算BMI及评估营养状况，并通过Nolla法评估其全景X光片以估算生物年龄。结果显示，生物年龄方面，最常见的为7岁（29.08%），最少见的为10岁（4.62%）；而实际年龄（chronological age）最常见的为8岁（24.62%）。研究还观察到，牙齿萌出最早的性别为女性（13.85%）。最后，体重不足儿童中加速萌出占主导（6.15%），健康体重儿童中延迟萌出占主导（21.54%），肥胖儿童中加速萌出占主导（9.23%）。超重儿童中延迟萌出占主导（7.69%），肥胖儿童中加速萌出占主导（7.69%）。
