The Next Stage in Periodontal Therapy
― Root Morphology as the Key to Successful Treatment ―

歯周治療 Next Stage
～歯根形態を制する者は歯周治療を制す！見えない領域を読み解くKey～

How clearly can you visualize the subgingival environment during periodontal treatment? This session will introduce ways to understand root morphology in three dimensions, approaches for predicting root surface anatomy from clinical findings, and practical techniques for managing challenging areas. By exploring the “why” behind subgingival instrumentation, the speakers will share practical insights that can be applied in daily clinical practice.

Clinical Considerations and Root Morphology in Japanese patients : Learning Root Surfaces Through 3D Images

Understanding 3D root morphology: Moving beyond 2D textbook illustrations
Visualizing root surface anatomy through probing: Applying anatomical knowledge to accurate root surface detection
Mastering root grooves: Strategies for thorough and predictable root debridement
Understanding furcation anatomy: Recognizing the limitations of root debridement

Why does hard calculus form so quickly on the CEJ, even though textbooks depict it as smooth?
For example, on the distal surface of the last molar, there may be a deep pocket without pus discharge, and calculus may be present but impossible to remove. Furthermore, when debridement is performed on the mesial surfaces of maxillary premolars or mandibular canines but the pocket remains, how far does a Grade III enamel projection extend into the furcation?
Do you encounter situations like these in your daily clinical practice?
In this session, I would like to explore these possible causes from the perspective of root anatomy using 3D images.

Clinical decision-making in periodontal therapy: Integrating radiographic and clinical findings for root surface detection

Root surface detection begins before instrumentation: A clinical thought process for predicting root surface conditions
Root surface detection extends beyond probing: Using radiographic and clinical findings to guide tactile assessment
What distinguishes effective root surface detection from ineffective root surface detection in SRP
How the quality of root surface detection influences SRP, re-evaluation, and long-term maintenance

Root surface detection is an extension of the periodontal examination, and successful periodontal therapy depends on a systematic approach based on clinical findings rather than blind instrumentation. This lecture will demonstrate how to integrate the patient's chief complaint, radiographic findings, intraoral photographs, and knowledge of root anatomy to develop a mental image of the subgingival root surface before instrumentation begins. The lecture will also discuss the use of dedicated exploratory instruments for accurate calculus detection to avoid unnecessary SRP, appropriate decision-making during re-evaluation, and practical techniques for improving root surface detection skills that can be readily applied in daily clinical practice.

Advancing SRP skills: Managing challenging sites and furcation involvement

Understanding why certain areas remain difficult to instrument during SRP
Understanding furcation involvement with confidence
Mechanical plaque control that leads to predictable clinical outcomes

Have you ever felt that certain areas remain difficult to debride during SRP, such as deep periodontal pockets or sites with complex root anatomy? This lecture will identify the factors that make instrumentation challenging and explain practical approaches that can be applied in daily clinical practice. Particular attention will be given to furcation involvement, an area in which many clinicians lack confidence, by reviewing its anatomical characteristics and organizing the clinical reasoning and technical steps required during SRP. In addition, considering the limitations of mechanical plaque control, the lecture will focus on improving assessment and intervention skills that lead to better treatment outcomes, greater clinical confidence, and more precise maintenance care.
