This periodontal probe is recommended by the German Periodontology Society. It allows you to measure the periodontal screening index (PSI). The PSI provides the first important information about the presence of periodontitis. The entire periodontium is checked tooth by tooth. The 0.5 mm ball tip prevents injuries in the gingival sulcus and automatically responds to uneven surfaces and protruding filling edges. PSI levels should be measured and documented regularly in all children starting at the age of 6. Treatment costs are reimbursable. Made of stainless steel. Autoclavable.
