480 men, 20 years, no toothbrushes: Löe's Sri Lanka study
Sri Lanka, 1970: Löe followed 480 labourers with no oral hygiene at all. By 45, 8% had lost every tooth and 11% almost nothing. What the data say.
Bálint Orbán: one of the greatest periodontists fled Nazism
Bálint Orbán fled Nazism in 1938. In Chicago he rebuilt modern periodontology. What remains today of the Vienna School.
Ninety Years Old — and Almost All Their Teeth
Prevention and recalls: maintenance is statistics. The reward is patients in their eighties and nineties who still have most of their own teeth.
Chronic Stress and Periodontal Bone Loss — The Mechanism
Chronic stress consumes the bone around the teeth through the HPA axis, cortisol, and the collapse of IL-10. The molecular mechanism, and 4 ways to break it.
What's Behind the Surge in So-Called 'Atrophic' Implant Cases?
Untreated periodontitis, immediate loading that flattens bone, mass extractions, re-treatments: why 'atrophic' implant cases keep surging. Atrophy we create.
Zone A and Zone B: The Histology of the Peri-Implant Biological Seal
Zone A (40 μm, avascular, fibroblast-rich) seals the implant. Zone B (160 μm, collagenous, vascularized) supports it. Moon et al., 1999.
Gummy Smile: Your Teeth Are Already Beautiful, the Gum Is Hiding Them
Too much gum when you smile? Often the teeth are normal, just covered: passive eruption isn't finished yet. Veneers aren't the answer. What to do instead.

The Groove Nobody Checks: Mesial Concavity and Periodontitis in First Premolars
The mesial concavity of the maxillary first premolar is present in 65–100% of cases and worsens periodontitis. A CBCT study on 343 teeth explains why.

Osteoporosis and periodontitis share biology and risk factors: meta-analysis on 19,611 patients and the critical four-year window after menopause.
Occlusal Trauma Does Not Prevent Periodontal Healing
Lindhe and Ericsson (1976) demonstrate that occlusal trauma does not impair healing after periodontal surgery, provided plaque is removed.
