Objective
• In this tutorial you will learn:– ODU 11/12 Explorer History– ODU 11/12 Instrument Design, Features & Benefits– ODU 11/12 Instrumentation
History• The ODU 11/12 explorer was designed and developed by Hu-Friedy in conjunction with Old Dominion University (ODU) Department of Dental Hygiene.
• The ODU 11/12 explorer was modeled after the Gracey 11/12.

Design
• Shank– Gracey 11/12 contra angle shank design- provides
for better adaptation to interproximal and curved surfaces.
• Working End– Small, fine tip and rounded back- for easier insertion
into deep and narrow pockets. • Universal Application
– The universal characteristics of the ODU 11/12 explorer make it ideal for exploring the entire dentition with a single instrument.
• Duraspond™– Explorers are made with Duraspond- an alloy that
provides exceptional tactile sensitivity, flexion and durability.
The ODU 11/12 is a double-ended explorer with mirror-image working ends.
11/12 ODU Explorer• To Correctly Adapt:
– Place Tip Interproximally So That Terminal Shank Is Parallel To The Tooth Surface
• Indications for use: – Exploration of the entire
dentition– Subgingival Use– Calculus detection in
deep pockets– May be used during all
assessment and treatment planning
