Abstract

Aim: To assess caries prevalence and its association with dental biofilm presence and body mass index (BMI) in children.

Materials and methods: In this cross-sectional study, 88 children aged 2-12 years were examined. The presence of dental caries was evaluated using the International Caries Detection and Assessment System (ICDAS) II criteria, with caries prevalence and index (dmft/DMFT) calculated based on established codes equivalent to World Health Organization standards (ICDAS II E-G/4-6). Dental biofilm was assessed using a standardized index, and nutritional status was determined by calculating BMI. To analyze the relationships between caries experience (dmft and DMFT) and the independent variables of weight, height, BMI, and dental biofilm index, a multiple linear regression analysis was performed using SPSS v25.0.

Results: A high prevalence of dental caries was observed in the study population. For primary teeth, caries prevalence (ICDAS 2-6) ranged from 15.9% to 52.3%, with a mean of approximately two affected teeth per child. In permanent teeth, the prevalence for initial caries lesions (ICDAS II code 2) reached 75%, with an average of three affected teeth per child. A statistically significant correlation was identified between BMI, dental biofilm index, and the DMFT score. Notably, a child's weight demonstrated a moderate negative impact on their DMFT score, explaining 45% of the variance (η² = 0.45).

Conclusion: The findings reveal a high burden of dental caries among children in the surveyed rural Ecuadorian communities. The significant association between a lower BMI and a higher caries index, alongside the influence of dental biofilm, underscores the intricate relationship between nutritional status, oral hygiene, and oral health. These results highlight the need for integrated public health interventions that address both malnutrition and oral hygiene to mitigate the high prevalence of dental caries in this and similar populations.

厄瓜多尔两个地区土著儿童龋齿、牙生物膜和体重指数之间的关系：一项横断面研究。

目的：探讨儿童龋患病率及其与牙生物膜存在和体重指数（BMI）的关系。材料与方法：在本横断面研究中，对88名2-12岁的儿童进行了调查。使用国际龋齿检测和评估系统（ICDAS） II标准评估龋齿的存在，并根据与世界卫生组织标准（ICDAS II E-G/4-6）等效的既定代码计算龋齿患病率和指数（dmft/ dmft）。采用标准化指数评估牙生物膜，通过计算BMI确定营养状况。采用SPSS v25.0软件进行多元线性回归分析龋病（dmft和dmft）与体重、身高、BMI、牙生物膜指数等自变量的关系。结果：在研究人群中观察到高龋患病率。对于乳牙，龋齿患病率（ICDAS 2-6）从15.9%到52.3%不等，平均每个儿童约有两颗蛀牙。在恒牙中，初始龋齿病变（ICDAS II代码2）的患病率达到75%，平均每个儿童有3颗受影响的牙齿。BMI、牙生物膜指数和DMFT评分之间存在显著的统计学相关性。值得注意的是，儿童的体重对他们的DMFT得分表现出适度的负面影响，解释了45%的方差（η²= 0.45）。结论：研究结果显示，在接受调查的厄瓜多尔农村社区中，儿童患龋齿的负担很高。较低的身体质量指数和较高的龋齿指数之间的显著关联，以及牙齿生物膜的影响，强调了营养状况、口腔卫生和口腔健康之间的复杂关系。这些结果强调需要采取综合公共卫生干预措施，解决营养不良和口腔卫生问题，以减轻这一人群和类似人群中龋齿的高发率。

期刊介绍： It is a journal aimed for research, scientific facts and details covering all specialties of dentistry with a good determination for exploring and sharing the knowledge in the medical and dental fraternity. The scope is therefore huge covering almost all streams of dentistry - starting from original studies, systematic reviews, narrative reviews, very unique case reports. Journal scope is not limited to these subjects and is more wider covering all specialities of dentistry follows: -Preventive and Community dentistry (Dental public health)- Endodontics- Oral and maxillofacial pathology- Oral and maxillofacial radiology- Oral and maxillofacial surgery (also called oral surgery)- Orthodontics and dentofacial orthopedics- Periodontology (also called periodontics)- Pediatric dentistry (also called pedodontics)- Prosthodontics (also called prosthetic dentistry)- Oral medicine- Special needs dentistry (also called special care dentistry)- Oral Biology- Forensic odontology- Geriatric dentistry or Geriodontics- Preventive and Social Medicine (Public health)- Our journal appreciates research articles pertaining with advancement of dentistry, preventive and community dentistry including oral epidemiology, oral health services research, oral health education and promotion, behavioral sciences related to dentistry, dental jurisprudence, ethics and oral health, economics, and quality assessment, recent advances in preventive dentistry and community dentistry.
