Secondary caries is reported as one of the most important reasons for replacing restorations. The patient's general caries risk plays an important role in the development of secondary caries. The connection, at the patient level, between various factors, the risk of caries and restoration factors, such as the presence of a gap and the kind of restoration material, deserves additional investigation. The minimum gap width in which secondary caries can develop is most likely less than 100 µm and could depend on the patient's caries risk. Composite restorations seem more susceptible to secondary caries than amalgam restorations in patients with high caries risk. So far, there is no unambiguous explanation for this difference. The prevention of secondary caries is comparable to that of primary caries and stresses the importance of fluoride, diet and oral hygiene.
继发龋被认为是更换修复体的最重要原因之一。患者的总体龋病风险在继发龋的发生中起着重要作用。在患者层面，各种因素、龋病风险与修复因素（如间隙的存在和修复材料的种类）之间的联系值得进一步研究。继发龋能够发生的最小间隙宽度很可能小于100微米，并且可能取决于患者的龋病风险。在高龋病风险患者中，复合树脂修复体似乎比银汞合金修复体更容易发生继发龋。到目前为止，对于这种差异尚无明确的解释。继发龋的预防与原发性龋的预防类似，强调了氟化物、饮食和口腔卫生的重要性。
