Objectives:
As periodontal disease preponderates in adults, early detection and interventional regime is urgently needed. However, there is lack of evidence-based data on evaluation of population-based intervention programme related to periodontal disease. The aim of this study was to assess the efficacy of intervention regime on early periodontal disease identified from a community-based periodontal survey.
Method:
By randomization, 60 subjects were allocated to the intervention group and 49 to the control group respectively. Status on periodontal disease of participants was evaluated at entry and re-evaluated after intervention at 1-month and 18-month follow-up respectively. Primary outcome evaluated was based on Community Periodontal Index and Loss of Attachment on sextant level.
Results:
The efficacy of intervention was significant in Community Periodontal Index (P<0.001) but not in Loss of Attachment (P=0.53) at 1-month and 18-month follow-up.
Conclusion:
The improvement of periodontal disease owing to intervention regime was seen in Community Periodontal Index but not Loss of Attachment as yet at 18-month follow-up after intervention.
