The relationship between high dietary intakes of sugar (sucrose) and dental caries is well established. Processed sugars and starches have been associated with greater dental caries experience in retrospective studies. The aim of this systematic review was to determine the relationship between the consumption of processed sugar- and starch-containing foods, the frequency of consumption of these foods, and dental caries. Prospective studies were identified in databases searched from 1970 to July 2020, and relevant retrieved papers that examined associations between the consumption of sugar- and starch-containing foods by human participants and dental caries were eligible for inclusion. Five cohort studies were identified for inclusion, all of which evaluated caries risk in young children or pre-adolescents. The between-meal consumption of processed sugar- and starch-containing foods was consistently found to be associated with greater caries experience. There were mixed findings on total consumption of processed sugar- and starch-containing foods, owing to a range of confounding factors, including the simultaneous consumption of caries-protective foods at mealtimes. Although there is a paucity of research of the dietary effects of frequent consumption of processed sugar- and starch-containing foods on dental caries, there is some evidence of plausible associations between this dietary behaviour and dental caries. Future research should investigate the effectiveness of interventions to change the dietary behaviour of high-frequency consumption of processed sugar- and starch-containing foods to decrease the risk of dental caries.
高糖（蔗糖）饮食与龋齿之间的关系已得到充分证实。在回顾性研究中，加工糖和淀粉已与更大的龋齿经历相关联。本系统评价的目的是确定加工糖和淀粉类食物的消耗、这些食物的消耗频率与龋齿之间的关系。从 1970 年至 2020 年 7 月，在数据库中确定了前瞻性研究，并且有相关检索论文检查了人类参与者消耗含糖和含淀粉的食物与龋齿之间的关联，这些论文有资格被纳入研究。确定了 5 项队列研究，这些研究均评估了儿童或青春期前儿童的龋齿风险。发现餐间食用加工糖和淀粉类食物与更大的龋齿经历密切相关。由于存在一系列混杂因素，包括在进餐时同时摄入防龋食物，因此对加工糖和淀粉类食物的总消耗的研究结果存在差异。尽管关于频繁食用加工糖和淀粉类食物对龋齿的饮食影响的研究很少，但有一些证据表明这种饮食行为与龋齿之间存在合理的关联。未来的研究应调查改变高频率食用加工糖和淀粉类食物的饮食行为以降低龋齿风险的干预措施的有效性。
