Q: How often would you repeat Scaling and Root Planing?
A: Well, technically you should never have to repeat SRP if it is done correctly and on a periodontal maintenance program. Let’s use an example. A patient comes in after an absence for about 3 years with 5 mm probing depths and bleeding throughout. Subgingival calculus is everywhere and they need SRP. If you do the SRP thoroughly, reevaluate and they now have normal pocketing you should keep them on 3 months for the next year. If they can maintain a good home care routine and comply with regular recalls, then they should be fine forever. If they skip steps, or slack off then SRP will need to be repeated.
