Objectives: To monitor the efficacy of periodontal maintenance whether conducted in a specialist periodontology clinic or in the practice of the referring general dentist. Materials and Methods: Thirty‐five subjects with a diagnosis of moderate–severe chronic periodontitis who were referred to the specialist clinic received periodontal non‐surgical therapy. Following a 6‐month healing phase, subjects were randomly allocated to one of two groups: A ( n =18, periodontal maintenance provided within the specialist clinic) or B ( n =17, periodontal maintenance provided by the referring general dentist in accordance with written instructions provided by the specialist). All subjects were examined at months 0 (corresponding to 6 months post‐completion of non‐surgical therapy), 6 and 12. Full‐mouth plaque index (PI), % bleeding on probing (%BOP) and probing depth (PD) measurements were recorded. PDs were also recorded at eight test sites which, prior to non‐surgical therapy, exhibited PD 5–8 mm, BOP and radiographic alveolar bone loss. Standardized radiographs were exposed at test sites at months 0 and 12, and bone changes assessed using digital subtraction radiography (DSR). Results: As a result of the non‐surgical therapy, statistically significant improvements in all clinical parameters were recorded. In the maintenance period, mean PI increased significantly from months 0 to 12 ( p <0.05), but this increase did not differ significantly between groups A and B ( p >0.05). No other clinical parameters changed significantly in the maintenance phase of the study. Reductions in %BOP, mouth mean PD and mean test sites PD achieved by the non‐surgical therapy were maintained and did not differ significantly whether subjects were allocated to group A or group B ( p >0.05). Current smokers had significantly deeper PD than non‐smokers and former smokers at all time points ( p <0.05), although otherwise, smoking status did not affect the outcomes of the study. DSR analysis identified statistically non‐significant, slight, alveolar bone loss in both groups between months 0 and 12. Conclusion: In the short term, periodontal maintenance can be provided in general dental practice with the same expected outcomes compared with maintenance that is provided in a specialist clinic, providing that general dentists are given specific instructions regarding the maintenance regimen. A strong emphasis on effective plaque control is necessary.
