If there is a reduction of probing depths after SRP but mobile anterior mandibular teeth remain, what is the recommended action?

When there is a reduction of probing depths after scaling and root planing (SRP), yet mobile anterior mandibular teeth persist, the recommended action is to consider guided tissue regeneration (GTR) or to engage in periodic evaluation. This recommendation stems from the understanding that mobile teeth may still be retained if there is potential for periodontal regeneration and healing to occur.

Guided tissue regeneration is a procedure that aims to restore the supporting structures of the teeth by allowing the periodontal ligament, cementum, and alveolar bone to regenerate in a controlled manner. If the mobility is not severe and there is a favorable prognosis for regeneration, GTR offers an opportunity for improvement without immediately resorting to extraction.

Periodic evaluation allows for monitoring of the condition over time, giving the clinician a chance to assess whether the teeth have stabilized or if additional interventions may be required. Regular check-ups help in determining the success of nonsurgical interventions and offer a chance to reassess treatment plans.

Immediate extraction would not be the best approach unless absolutely necessary, as teeth that may respond positively to further treatment could unnecessarily be lost. Nonsurgical periodontal therapy could serve as an adjunct but does not specifically address the need for regenerative options in cases of persistent mobility after initial treatment. Placement of a
