Periodontics

What Is Periodontics?

Periodontics is the branch of dentistry concerned with the prevention, diagnosis, and treatment of diseases affecting the supporting structures of the teeth the gingiva (gums), periodontal ligament, cementum, and alveolar bone. These structures form the foundation on which every tooth depends for its stability and long-term survival.

When they are compromised by disease, even technically excellent restorations crowns, veneers, or implants are undermined.

Periodontal health is not a preliminary consideration in dental treatment; it is a prerequisite for all of it.

Periodontal disease is one of the most prevalent chronic conditions affecting adults globally.

A 2025 narrative review from Ewha Womans University College of Medicine confirms that periodontitis affects between 7.4% and 11.2% of adults worldwide, with prevalence increasing substantially with age.

A separate NIH/PMC review reports that severe periodontitis now affects 1.1 billion individuals globally making it more prevalent than cardiovascular disease.

Despite this, it remains largely underdiagnosed and undertreated because its early stages are often painless and its consequences accumulate silently over years.

The clinical objective of periodontal treatment is to arrest the disease process eliminating the bacterial biofilm driving the destructive inflammatory response, reducing pocket depths to maintainable levels, and where possible regenerating lost bone and attachment.

Successful periodontal treatment requires both high-quality clinical intervention and a structured maintenance programme, as periodontitis is a chronic condition that does not resolve with a single course of treatment.

Stages of Periodontal Disease

Periodontal disease exists on a spectrum from early, fully reversible gingival inflammation to advanced attachment and bone loss that threatens the long-term survival of the affected teeth.

The 2018 World Workshop on the Classification of Periodontal and Peri-Implant Diseases established a staging and grading system that guides clinical diagnosis and treatment planning, and is used at Vitrin Clinic for every periodontal assessment.

Gingivitis

Gingivitis is inflammation of the gingiva caused by the accumulation of bacterial plaque at and below the gum margin.

It is characterised by redness, swelling, and bleeding on probing but crucially, no attachment loss or bone destruction has yet occurred.

Gingivitis is fully reversible with professional debridement and improved patient oral hygiene.

It is the only stage of periodontal disease that resolves completely without permanent structural consequences making early intervention the highest-value clinical action in periodontics.

Mild to Moderate Periodontitis

Once attachment loss and radiographic bone loss are detectable, the disease has progressed to periodontitis a stage at which the tissue destruction is not reversible, but is arrestable with treatment.

Mild to moderate periodontitis is characterised by pocket depths of 4 to 6 mm, clinical attachment loss of 1 to 4 mm, and radiographic bone loss confined to the coronal or middle third of the root.

Non-surgical treatment thorough subgingival debridement and patient education is the first-line intervention and achieves significant clinical improvement in the majority of cases.

Severe Periodontitis

Severe periodontitis is defined by pocket depths of 6 mm or more, clinical attachment loss exceeding 5 mm, bone loss extending to the middle or apical third of the root, and in Stage IV, tooth loss directly attributable to periodontitis.

Furcation involvement disease entering the area between the roots of multi-rooted teeth substantially increases treatment complexity.

Severe cases often require a combination of non-surgical and surgical periodontal therapy, and carry a more guarded prognosis for affected teeth depending on residual bone support and patient compliance with maintenance.

Peri-Implant Disease

Peri-implantitis the implant equivalent of periodontitis is inflammation and bone loss around an osseointegrated implant.

Like periodontitis, it is driven by bacterial biofilm and progresses silently in its early stages.

Patients with a history of periodontitis are at significantly elevated risk of peri-implantitis, which is why periodontal health must be established and maintained before implant placement and why ongoing monitoring of implants within a structured maintenance programme is essential for their long-term survival.

Periodontitis Is Not Just a Dental Problem

The inflammatory mediators produced in an active periodontitis lesion do not remain confined to the gum tissue.

Periodontal pathogens and their products enter the systemic circulation, driving low-grade chronic inflammation at distant organ sites.

A 2023 consensus report confirmed that periodontitis is independently associated with cardiovascular disease, type 2 diabetes, COPD, and obstructive sleep apnea.

A bidirectional relationship exists with diabetesuntreated periodontitis worsens glycaemic control, and successful periodontal treatment measurably reduces HbA1c levels. Treating periodontal disease is treating the whole patient, not just the mouth.

Necrotising Periodontal Disease

Necrotising gingivitis and necrotising periodontitis are acute, rapidly progressing presentations characterised by necrosis and ulceration of the interdental papillae, pain, bleeding, and in some cases systemic symptoms including fever and lymphadenopathy.

They are associated with significant psychological stress, malnutrition, immunosuppression, and systemic disease.

Prompt professional debridement, patient education, and in some cases systemic antimicrobials are required. These presentations should not be managed with self-treatment and require immediate clinical assessment.

Non-Surgical vs. Surgical Periodontal Treatment

The choice between non-surgical and surgical approaches depends on the severity and distribution of disease, patient compliance, anatomical factors, and the re-evaluation findings following non-surgical treatment.

The following comparison is based on evidence from systematic reviews and clinical guidelines.

Why Clinical Approach Matters

Periodontal treatment is one of the most protocol-dependent procedures in dentistry its outcomes are directly determined by the thoroughness of the debridement performed, the accuracy of the diagnosis and staging, the patient's compliance with oral hygiene and maintenance, and the clinician's ability to identify and manage the systemic and local risk factors that influence treatment response.

The single most important predictor of long-term periodontal treatment success is maintenance compliance. Research from systematic reviews of post-interventional maintenance protocols consistently confirms that patients who attend regular periodontal maintenance appointments maintain significantly better clinical parameters over time than those who do not regardless of the quality of the active treatment they received.

An excellent course of non-surgical therapy followed by no maintenance is a temporary benefit, not a lasting one.

The systemic dimension further elevates the importance of clinical rigour in periodontal treatment.

A patient with diabetes and periodontitis who receives thorough periodontal treatment and achieves disease control receives a measurable improvement in HbA1c alongside their dental benefit confirmed across multiple systematic reviews and meta-analyses from international research groups.

The Karolinska Institute in Stockholm has specifically documented this bidirectional relationship, confirming that treating periodontitis lowers blood glucose in diabetic patients.

Periodontal treatment is systemic treatment, and it should be delivered with that understanding.

Vitrin Clinic Standard

• Full-mouth charting at every assessment not a spot-check

Your periodontal status is measured at all six sites of every tooth. Disease that is not measured is not managed and at Vitrin Clinic, it is always measured.

• Debridement under local anaesthesia thorough, not superficial

Non-surgical treatment at Vitrin Clinic is performed under local anaesthesia so the full depth of every pocket is treated without patient discomfort limiting access.

Thoroughness determines outcomes.

• No restorative treatment until periodontal health is confirmed

Crowns, veneers, and implants are not placed until your gum health is assessed and stable. Restorations placed into active periodontal disease are placed into an unstable foundation.

• Maintenance is part of treatment not an optional extra

Your long-term maintenance schedule is discussed and planned as part of your active treatment plan. Periodontal disease reactivates without maintenance and at Vitrin Clinic we plan for the long term from the outset.
