<h2 style="text-align:justify">KaVo SMARTmatic ENDO S81 / S321 Maintenance: Care Habits for Long, Smooth Endo Days</h2>

&nbsp;

Endodontic procedures can run long, and the contra-angle driving the file works the whole time. For the KaVo SMARTmatic ENDO S81 and ENDO S321, good care starts before the case even begins, with the right motor, and continues with careful reprocessing afterwards.

&nbsp;

This guide brings together what KaVo officially says about caring for these instruments.

<h2 style="text-align:justify">ENDO CARE IN BRIEF</h2>

&nbsp;

Pair each model with the motor KaVo recommends. Reprocess after every case. Lubricate only with KaVo Spray or QUATTROcare PLUS. Care for O-rings with KaVo products, never Vaseline. Respect the maximum sterilization temperature.

&nbsp;

<h2 style="text-align:justify">Maintenance Starts With the Right Motor</h2>

&nbsp;

Using each contra-angle as designed is part of looking after it:

&nbsp;

Both models run up to a 40,000 rpm maximum operating speed and take endodontic files with a 2.35 mm shaft.

&nbsp;

<h2 style="text-align:justify">After Every Case</h2>

&nbsp;

<ol>
	<li style="text-align: justify;">Remove the file.</li>
	<li style="text-align: justify;">Reprocess promptly so debris does not dry on the instrument.</li>
	<li style="text-align: justify;">Clean and disinfect manually or in a thermal disinfector. KaVo confirms both are allowed for SMARTmatic instruments.</li>
	<li style="text-align: justify;">Lubricate with KaVo Spray or the QUATTROcare PLUS.</li>
	<li style="text-align: justify;">Sterilize using the cycle in your instrument&#39;s instructions.</li>
</ol>

&nbsp;

<h2 style="text-align:justify">Lubrication: KaVo Products Only</h2>

&nbsp;

KaVo&#39;s SMARTmatic FAQ states that instrument maintenance must be carried out with KaVo Spray or the QUATTROcare PLUS.

<h2 style="text-align:justify">&nbsp;</h2>

<h2 style="text-align:justify">O-Rings: Small Parts, Big Job</h2>

&nbsp;

KaVo&#39;s care tips recommend replacing all O-rings together without sharp tools, using only KaVo-recommended oils (never Vaseline), and attaching and removing instruments in a straight line with a slight twist.

&nbsp;

<h2 style="text-align:justify">Sterilization Limits</h2>

&nbsp;

KaVo&#39;s international page lists SMARTmatic instruments as sterilizable to 138&deg;C (280.4&deg;F). Its US page lists up to 135&deg;C (275&deg;F). Use the cycle in the instructions supplied with your instrument and never exceed the limit that applies to it.

&nbsp;

<h2 style="text-align:justify">Endo Care Mistakes to Avoid</h2>

<ol>
	<li style="text-align: justify;">Running the S81 on an air motor or the S321 on an electric motor.</li>
	<li style="text-align: justify;">Leaving the contra-angle to sit before reprocessing.</li>
	<li style="text-align: justify;">Reaching for a generic handpiece oil instead of KaVo Spray.</li>
	<li style="text-align: justify;">Greasing O-rings with Vaseline.</li>
	<li style="text-align: justify;">Exceeding the maximum sterilization temperature.</li>
</ol>

<h2 style="text-align:justify">KaVo ENDO S81 / S321 Maintenance FAQs</h2>

&nbsp;

<h3 style="text-align:justify">Which lubricant should I use on a KaVo ENDO contra-angle?</h3>

Only KaVo Spray or the QUATTROcare PLUS, according to KaVo&#39;s SMARTmatic FAQ.

&nbsp;

<h3 style="text-align:justify">Can I use a thermal disinfector?</h3>

Yes. KaVo&#39;s FAQ says SMARTmatic instruments are wash- and disinfectable in a thermal disinfector, and manual processing is also allowed.
