For restorative procedures on the lower right molars, which local anaesthetic technique is most likely to be administered?

The use of an inferior dental nerve block is the most suitable choice for restorative procedures on the lower right molars due to its effectiveness in providing profound anesthesia for the entire lower molar region. This technique targets the inferior alveolar nerve, which supplies sensation to the mandible's molar teeth and associated structures. By applying this method, dental professionals can achieve adequate pain control while performing procedures such as fillings or crowns on the lower right molars.

Considering the other techniques, infiltration is generally more effective for smaller areas and might not provide adequate anesthesia for larger teeth like molars due to the density of the mandibular bone. Intraligamentary injection is also more specific and typically used for localized treatment rather than more extensive restorative work. Lastly, a mental block primarily numbs the anterior mandible and does not provide anesthesia for the lower right molars, making it inappropriate for procedures involving these teeth. Thus, the use of the inferior dental nerve block stands out as the optimal technique in this scenario.
