<h2 style="text-align:justify"><strong><span style="font-size:18px">Common Clinical Mistakes Seen in Practice</span></strong></h2>

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

<p style="text-align:justify"><span style="font-size:18px">From a clinical standpoint, lens coating degradation in<a href="https://repair.dental/services/intra-oral-camera-repair/dexis-intraoral-camera-repair"> <span style="color:#2980b9">DEXIS intraoral camera</span></a>&nbsp;</span><span style="font-size:18px">units is often self-inflicted without dentists realizing it. In daily practice, I see clinicians aggressively cleaning the tube head window with alcohol wipes, assuming sterility equals safety. Over time, images begin showing subtle glare, washed-out contrast, or inconsistent density that cannot be corrected by exposure settings. Most dentists don&rsquo;t realize these are optical surface failures, not sensor or software issues. Continued use under these conditions increases retakes and compromises diagnostic confidence.</span></p>

<h2 style="text-align:justify"><strong><span style="font-size:18px">Why Anti-Reflective Coatings Fail</span></strong></h2>

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

<p style="text-align:justify"><span style="font-size:18px">Anti-reflective coatings are engineered at the micron level to minimize photon reflection and internal scatter before radiation exits the tube head. Repeated chemical exposure, abrasive wiping, and micro-particle contamination slowly strip or cloud this coating. Once degraded, photons scatter unpredictably, producing glare artifacts and contrast loss without reducing total radiation output enough to trigger error messages. Mechanical shock during transport further accelerates coating microfractures. This is why coating degradation progresses silently until image quality is clearly affected.</span></p>

<h2 style="text-align:justify"><strong><span style="font-size:18px">Diagnostic Identification of Coating Degradation</span></strong></h2>

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

<p style="text-align:justify"><span style="font-size:18px">Diagnosis relies on pattern recognition rather than system alerts. Clinically, dentists observe uniform haze across images, reduced contrast differentiation in dense anatomy, and inconsistent sharpness between identical exposures. Visual inspection of the external lens window may reveal dullness or fine surface clouding. Beam consistency testing using exposure phantoms helps differentiate coating failure from tube or generator issues. Without professional evaluation, coating damage is frequently misdiagnosed as sensor aging.</span></p>

<h2 style="text-align:justify"><strong><span style="font-size:18px">Treatment: Professional Optical Restoration</span></strong></h2>

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

<p style="text-align:justify"><span style="font-size:18px">Once coating degradation is confirmed, chairside correction is not possible. Repair.Dental provides worldwide portable X-ray repair with free shipping in the USA and Canada, and discounted international shipping. Service requests are initiated via website, phone, WhatsApp, or email. A shipping label is issued, and upon arrival, the unit undergoes full optical and radiation diagnostics. A detailed report and quote are shared, and repair begins only after approval. Turnaround time is typically 2&ndash;3 business days, extending to 3&ndash;5 business days for complex optical restoration cases. Treatment may involve lens replacement or controlled optical surface restoration followed by beam verification.</span></p>

<h2 style="text-align:justify"><strong><span style="font-size:18px">Dentist-Safe Checks and Clear Stop Points</span></strong></h2>

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

<p style="text-align:justify"><span style="font-size:18px">Dentists can safely review recent radiographs for uniform glare or contrast flattening and visually inspect the tube head window under proper lighting. Do not attempt polishing, scraping, or chemical treatment of the lens surface. Do not open the tube head or insert cleaning tools. Continued aggressive cleaning worsens coating loss and accelerates optical failure.</span></p>

<h2 style="text-align:justify"><strong><span style="font-size:18px">Cost Transparency and Clinical Value</span></strong></h2>

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

<p style="text-align:justify"><span style="font-size:18px">Repair costs vary depending on whether coating restoration or full lens replacement is required. Factors include optical component condition, beam recalibration needs, and post-repair exposure testing. Repair is significantly more cost-effective than full unit replacement and preserves existing workflow familiarity. Warranty coverage applies to restored or replaced components, and from a clinical economics perspective, repair reduces downtime while restoring diagnostic reliability.</span></p>

<h2 style="text-align:justify"><strong><span style="font-size:18px">How to Avoid Coating Degradation</span></strong></h2>

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

<p style="text-align:justify"><span style="font-size:18px">Prevention is primarily procedural. Use only manufacturer-approved cleaning materials and avoid excessive pressure during surface cleaning. Store the unit in a padded case to prevent dust contamination and mechanical shock. Maintain proper temperature and humidity conditions. Train staff to recognize early image glare patterns and report them before coating damage progresses. Annual professional inspection helps detect optical wear before clinical performance declines.</span></p>

<h2 style="text-align:justify"><strong><span style="font-size:18px">FAQ</span></strong></h2>

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

<p style="text-align:justify"><span style="font-size:18px"><strong>Does lens coating degradation affect radiation safety?</strong><br />
Yes indirectly. While output may remain stable, increased retakes elevate cumulative patient exposure.</span></p>

<p style="text-align:justify"><span style="font-size:18px"><strong>Can degraded anti-reflective coatings be repaired?</strong><br />
In many cases, yes. Professional optical restoration or lens replacement resolves the issue.</span></p>

<p style="text-align:justify"><span style="font-size:18px"><strong>Why doesn&rsquo;t the unit show an error code?</strong><br />
Coating failure affects beam quality, not system electronics, so alerts are rarely triggered.</span></p>

<p style="text-align:justify"><span style="font-size:18px"><strong>Does repair restore the original image contrast?</strong><br />
Yes. Proper optical restoration returns beam uniformity and contrast performance.</span></p>

<p style="text-align:justify"><span style="font-size:18px"><strong>Is calibration included after repair?</strong><br />
Yes. Optical and exposure calibration are mandatory before unit release.</span></p>

<p style="text-align:justify"><span style="font-size:18px"><strong>When is replacement better than repair?</strong><br />
Replacement is considered only if coating damage coincides with tube or generator failure.</span></p>
