Which factors are considered when selecting PRR vs conventional filling in a primary tooth?

Choosing between a preventive resin restoration and a conventional filling in a primary tooth is about aligning the lesion and the child’s situation with a treatment that preserves tooth structure and achieves a durable seal. Caries depth matters: PRR is typically favored when the caries is limited to the outer dentin and there’s no pulp exposure risk, allowing you to remove only softened tissue and seal the area with resin, rather than aggressively removing caries for a full conventional filling. Moisture control is crucial because resin bonding requires a dry field; if isolation isn’t achievable, PRR’s bonding may fail and a different approach becomes more reliable. The child’s cooperation influences feasibility—PRR can be quicker and less demanding, which is beneficial when behavior limits the time you can spend on a single visit. Prognosis and patient caries risk guide whether a preventive, sealant-like approach is appropriate to reduce future decay or whether a more definitive restoration is warranted. Cost is also a consideration, since PRR can be less expensive and less time-consuming in suitable cases. Flavor or tooth color are not primary determinants of this decision.
