Development of Clinical Pathway for Non-Surgical Management of Chronic Periodontitis
Last reviewed: March 2026
Key Findings
- The study developed a standardised clinical pathway for non-surgical periodontal treatment in the Malaysian healthcare context.
- Scaling and root planing (SRP) was confirmed as the foundational treatment modality, consistent with international evidence-based guidelines.
- The pathway incorporated systematic re-evaluation protocols to determine the need for adjunctive therapies or surgical referral.
- Standardised clinical pathways can improve treatment consistency, reduce variability in clinical outcomes, and enhance resource allocation in public dental services.
Background and Context
Chronic periodontitis is a prevalent inflammatory disease of the tooth-supporting structures — the periodontium — characterised by progressive destruction of the periodontal ligament and alveolar bone. The disease is driven by complex interactions between bacterial biofilms that accumulate on tooth surfaces and the host’s immune-inflammatory response, modulated by genetic susceptibility and environmental risk factors, most notably tobacco use and poorly controlled diabetes mellitus. Periodontitis has been recognised as the sixth most prevalent chronic disease globally and represents a significant burden on healthcare systems worldwide.
In Malaysia, the National Oral Health Survey has documented substantial rates of periodontal disease across the adult population, with prevalence increasing with age. The condition is of particular public health concern because of its association with systemic health outcomes: a growing body of evidence links periodontitis to increased risk of cardiovascular disease, adverse pregnancy outcomes, poor glycaemic control in diabetes, and respiratory infections. These associations have elevated periodontal health from a purely dental concern to a matter of broader public health significance.
The non-surgical management of chronic periodontitis centres on the mechanical removal of bacterial biofilm and calculus from tooth surfaces above and below the gumline through scaling and root planing (SRP). This procedure aims to create a biologically compatible root surface that facilitates healing of the periodontal tissues. Evidence from systematic reviews and the American Dental Association’s clinical practice guidelines supports SRP as the initial treatment of choice for patients with chronic periodontitis, with moderate benefit and a favourable risk-benefit profile. Adjunctive therapies — including locally delivered antimicrobials, systemic antibiotics, and host-modulating agents — may be considered for cases that do not respond adequately to mechanical debridement alone.
The Role of Clinical Pathways
Clinical pathways are structured, multidisciplinary care plans that detail the essential steps in the management of patients with specific clinical conditions. They serve several important functions in healthcare delivery: standardising care processes to reduce unwarranted variation, translating evidence-based guidelines into practical clinical workflows, improving communication among members of the healthcare team, facilitating quality monitoring and audit, and enhancing cost-effectiveness by reducing unnecessary investigations and treatments.
In the context of periodontal care, a clinical pathway for non-surgical management would typically encompass the initial assessment and diagnosis phase (including comprehensive periodontal charting, radiographic assessment, and risk factor identification), the active treatment phase (SRP with or without adjunctive therapies), the re-evaluation phase (conducted four to six weeks after completing active treatment to assess tissue response), and the maintenance phase (regular recall visits at three to six month intervals for professional plaque removal, monitoring, and reinforcement of home care).
The development of a clinical pathway specifically calibrated to the Malaysian healthcare context addresses practical considerations that differ from those in other countries: the public-private mix of dental service delivery, workforce composition (including the role of dental therapists and dental nurses in delivering periodontal care), patient demographic and risk factor profiles, and available resources for adjunctive therapies and specialist referral.
Evidence Base for Non-Surgical Periodontal Therapy
The evidence supporting non-surgical periodontal therapy as the initial approach to managing chronic periodontitis is robust. A network meta-analysis of studies included in the ADA clinical practice guideline demonstrated that SRP alone produces clinically meaningful improvements in probing depth reduction and clinical attachment gain. For patients with moderate to severe periodontitis, the ADA guideline additionally recommends systemic sub-antimicrobial dose doxycycline (20 mg twice daily for 3 to 9 months) as an adjunct to SRP, based on evidence that this host-modulating agent inhibits matrix metalloproteinase activity and provides additional improvements in clinical parameters.
The re-evaluation visit, typically scheduled four to six weeks after completion of active SRP, is a critical decision point in the clinical pathway. At this stage, comprehensive periodontal charting is updated and compared to baseline values. Sites with residual probing depths of 1 to 5 mm may be maintained with continued non-surgical management, including repeated instrumentation as needed and reinforced home care. Sites with persistently deep probing depths (generally 6 mm or greater) may require consideration of surgical intervention, including regenerative procedures for sites with intrabony defects or resective surgery for sites without favourable defect morphology.
Non-Surgical Periodontal Treatment Components
| Phase | Components | Timeline |
|---|---|---|
| Assessment | Periodontal charting, radiographs, risk factor assessment | Initial visit |
| Cause-related therapy | Oral hygiene instruction, SRP, correction of plaque-retentive factors | 2–4 visits over 2–6 weeks |
| Adjunctive therapy (if indicated) | Local antimicrobials, systemic sub-antimicrobial dose doxycycline | Concurrent with or after SRP |
| Re-evaluation | Updated charting, comparison with baseline, treatment response assessment | 4–6 weeks post-SRP |
| Maintenance | Professional plaque control, monitoring, risk factor management | Every 3–6 months ongoing |
Implications for Malaysian Dental Public Health
The development of a standardised clinical pathway for non-surgical periodontal management has direct relevance to the delivery of public dental services in Malaysia. The Ministry of Health operates an extensive network of dental clinics within public hospitals and community health centres, staffed by dental officers, dental therapists, and dental nurses. Standardised pathways can serve as practical tools for these practitioners, particularly in settings where specialist periodontal expertise is not readily available, by providing clear criteria for treatment planning, timing of re-evaluation, and thresholds for specialist referral.
Furthermore, clinical pathways facilitate clinical governance by establishing measurable quality indicators — such as the proportion of patients receiving re-evaluation within the recommended timeframe, the percentage achieving target probing depth reductions, and referral rates to periodontal surgery — that can be monitored and benchmarked across facilities. This is particularly valuable in the Malaysian public healthcare system, where demand for dental services often exceeds available capacity and efficient resource utilisation is essential.
Limitations
Clinical pathways inherently represent a simplified model of clinical decision-making and cannot account for every individual patient variation. Periodontitis severity, extent, and treatment response vary considerably between patients and even between different sites within the same patient. Pathways must therefore be applied with clinical judgment and adapted to individual circumstances. Additionally, the evidence base for adjunctive therapies continues to evolve, and pathways require periodic updating to reflect new evidence. The specific pathway developed in this study was designed for the Malaysian context and may require adaptation for other healthcare settings.
