# Zermmi Perio — Full Product Information > Intelligent periodontal charting and management platform for dental professionals. Last updated: 2026-05-09 Website: https://www.zermmi.com Contact: support@zermmi.com --- ## What is Zermmi Perio? Zermmi Perio is a free, browser-based periodontal charting tool designed for dentists, periodontists, dental hygienists, and dental students. It allows dental professionals to record pocket depths, bleeding on probing (BOP), gingival recession, tooth mobility, furcation involvement, plaque, and suppuration directly in the browser. The interactive chart updates in real time with a realistic visualization of the periodontium. No software installation, no account registration, and no credit card required — just open the browser and start charting. --- ## Core Features ### Fast Charting with Auto-Advance Enter probing depths using keyboard or number pad. The cursor automatically advances to the next site after each entry, allowing completion of a full-mouth periodontal chart in minutes. ### Two Chart Views - **Realistic view**: Detailed tooth anatomy with furcation arrows, ideal for chairside patient education. - **Abstract view**: Clean data grid with high-contrast numbers for fast clinical data entry and printing. ### Clinical Measurements - Pocket depth (PD): Color-coded — 1-3 mm clear, 4-5 mm orange, 6+ mm red - Bleeding on probing (BOP): Red dot marker - Recession: Red numeric overlay - Suppuration: Yellow dot marker - Plaque: Purple dot marker - Furcation: Grades I-III at root furcations - Mobility: Scores 1-3 ### Instant Statistics Summary Real-time calculation of key periodontal metrics: BOP score, plaque score, mean pocket depth, sites over 4mm, deepest pocket, and more. Updated automatically as you chart. ### PDF Export Generate professional PDF reports with one click. Each report includes automatic statistics summary with average probing depths, percentage of sites with BOP, and breakdown by tooth. PDFs carry your clinic branding (logo, name, contact details). ### JSON Export & Import Export chart data as JSON to archive or transfer between devices. Import JSON to resume charting or revisit previous sessions. ### Professional Branding Add your practice logo, clinic name, and contact information. All exports reflect your practice identity. No premium tier required. ### Multilingual Available in 11 languages: English, French (default), German, Spanish, Turkish, Portuguese, Danish, Dutch, Swedish, Hungarian, and Thai.
