On which set of teeth is sealant retention typically better?

Sealant retention is typically better on mandibular teeth due to several anatomical and functional factors. The premolars and molars in the mandibular arch generally have deeper pits and fissures compared to maxillary teeth, which can create more surface area for the sealant to adhere to. Additionally, the positioning of mandibular teeth often allows for better access during the application of the sealant, leading to a more effective bonding process.

Mandibular teeth also experience different occlusal forces and are generally subject to more wear and abrasion, which can influence the long-term retention of sealants. In contrast, maxillary teeth might have less retention because their silhouette and occlusal surfaces can be less conducive to the effective sealing material. The incisor and cuspid teeth, while important in the dental arch, typically do not have the same deep fissures that are ideal for sealant retention as seen in the posterior mandibular teeth.
