<h2>KaVo MASTERmatic M29 L Maintenance: Post-Case Care for KaVo&#39;s Endo Contra-Angle</h2>

&nbsp;

Endodontic cases can be long, and the instrument works the whole time. The KaVo MASTERmatic M29 L needs careful reprocessing at the end of every case to stay smooth and dependable.

&nbsp;

This guide focuses on what to do once the case is finished.

&nbsp;

<h2>The End-of-Case Checklist</h2>

&nbsp;

<ul>
	<li>
	Remove the instrument from the head.
	</li>
	<li>
	Start cleaning promptly so debris does not dry.
	</li>
	<li>
	Run KaVo&#39;s full preparation process.
	</li>
	<li>
	Lubricate with KaVo Spray or QUATTROcare PLUS.
	</li>
	<li>
	Sterilize no higher than 135&deg;C (275&deg;F).
	</li>
</ul>

<h2>KaVo&#39;s Preparation Stages</h2>

&nbsp;

KaVo&#39;s MASTERmatic page points to its preparation video: external and internal cleaning, internal disinfection, manual maintenance and sterilization. KaVo lists the series as thermo-disinfectable.

&nbsp;

<h2>Heads and Shank</h2>

&nbsp;

Since KaVo&#39;s flyer describes the M29 L as a shank for INTRA LUX heads, every head used during the case needs full reprocessing too.

&nbsp;

Rotation not as smooth after a long case? Let Repair.Dental check it before the next endo appointment.

&nbsp;

<h2>Lubrication and Cooling</h2>

&nbsp;

Use KaVo Spray or the QUATTROcare PLUS. KaVo&#39;s care tips warn against descaling agents and root canal needles for clearing spray channels; use dedicated nozzle needles instead.

<h2>&nbsp;</h2>

<h2>Mistakes After Endo Cases</h2>

&nbsp;

<ol>
	<li>
	Leaving the instrument to sit before cleaning.
	</li>
	<li>
	Skipping lubrication after a long case.
	</li>
	<li>
	Clearing spray channels with a root canal needle.
	</li>
	<li>
	Forgetting to reprocess spare heads.
	</li>
	<li>
	Exceeding 135&deg;C.
	</li>
</ol>

&nbsp;

<h2>M29 L Care FAQs</h2>

Why use a nozzle needle instead of a root canal needle?

KaVo&#39;s care tips warn that root canal needles can damage spray channels.

Yes, according to KaVo.
