<h2>KaVo INTRA Head L66 B Maintenance: Post-Endo Care for a 3:1 Reduction Head</h2>

&nbsp;

Root canal preparation can leave fine debris where you least want it: in and around the chuck. For the KaVo INTRA head L66 B, the moments after an endo case decide how smoothly it runs next time.

&nbsp;

This guide is built around that post-case window.

&nbsp;

Quick answer: After each use, remove the instrument, clean the L66 B inside and out, disinfect, lubricate with KaVo products, and sterilize at no more than 135&deg;C. KaVo lists INTRA heads as thermo-disinfectable.

<h2>What Happens in the First Few Minutes After a Case?</h2>

&nbsp;

<ul>
	<li>
	Remove the root canal instrument or bur.
	</li>
	<li>
	Remove the L66 B from the shank with the quick-action safety retention collar.
	</li>
	<li>
	Start cleaning promptly so debris does not dry.
	</li>
</ul>

<h2>Which KaVo Products Help?</h2>

&nbsp;

CLEANspray and DRYspray offer alcohol-free manual internal cleaning and drying. KaVo Spray and the QUATTROcare PLUS handle lubrication.

&nbsp;

Low-speed rotation not as smooth as it was? Have Repair.Dental: check your L66 B before your next endo case.

&nbsp;

<h2>Myth vs. Fact</h2>

&nbsp;

<ul>
	<li>
	Myth: a slow head does not need much lubrication. Fact: reduction gearing still relies on proper care after every use.
	</li>
	<li>
	Myth: clearing a channel with a root canal file is fine. Fact: KaVo&#39;s care tips warn that root canal needles can damage spray channels; use dedicated nozzle needles.
	</li>
</ul>

&nbsp;

<h2>How Should You Store It?</h2>

&nbsp;

Store the L66 B only after full reprocessing, sterile and labeled, so it is ready for the next endodontic case.

&nbsp;

<h2>Mistakes to Avoid</h2>

&nbsp;

<ol>
	<li>
	Letting endo debris dry before cleaning.
	</li>
	<li>
	Using generic oil instead of KaVo products.
	</li>
	<li>
	Using descaling agents.
	</li>
	<li>
	Sterilizing above 135&deg;C.
	</li>
</ol>

&nbsp;

<h2>How Often Should You Inspect the L66 B?</h2>

&nbsp;

Make a quick check part of every case: insert and release a 2.35 mm instrument, and listen to the head at low speed before starting. Because KaVo lists the L66 B down to 35 rpm, roughness at the bottom of its range is often the first sign that care has slipped.

&nbsp;

<h2>Does the Shank Need Care Too?</h2>

&nbsp;

Yes. The L66 B sits on a shank such as the MASTERmatic M20 L, which has its own light path, spray filter and coupling O-rings. Caring for the head alone is only half the job. Our Preventive Maintenance Agreement can cover both parts on a regular schedule.

&nbsp;

<h2>L66 B Care Questions</h2>

&nbsp;

Can the L66 B be thermo-disinfected?

Yes. KaVo lists INTRA heads as heat-disinfectable.

&nbsp;

What is the sterilization limit?

135&deg;C, according to KaVo.
