A complicated crown fracture in a non-vital primary tooth typically requires a pulpectomy as the recommended treatment. In this scenario, the pulp of the tooth is already non-vital, meaning it is no longer alive or functional. A pulpectomy involves removing the entire pulp tissue from the root canals of the tooth, disinfecting the canals, and filling them with an appropriate material to prevent infection and maintain the tooth's function and integrity. This procedure can help preserve the primary tooth until it naturally exfoliates and makes way for the permanent successor tooth.

Options B, C, and D are not the recommended treatments in the case of a complicated crown fracture in a non-vital primary tooth. Extraction may be considered if the tooth is unrestorable, but preserving primary teeth whenever possible is preferred to maintain space for the permanent teeth. Rigid splinting is typically used for traumatic injuries involving tooth mobility, not for complicated crown fractures. A soft diet may be recommended post-operatively to prevent further damage or discomfort, but it is not the primary treatment for a complicated crown fracture in a non-vital primary tooth.
