<p style="text-align:justify"><span style="font-size:18px">In daily practice, I see <a href="https://repair.dental/services/intra-oral-camera-repair/planmeca-intraoral-camera-repair">Planmeca intraoral camera</a>&nbsp;units produce grainy or inconsistent images after multiple consecutive exposures, especially during busy clinical sessions. The exposure settings remain unchanged, positioning is correct, yet image noise increases and fine anatomical details become harder to interpret. From a clinical standpoint, this pattern often reflects thermal noise buildup within the sensor and signal processing circuitry. Thermal noise not only degrades diagnostic confidence but also increases the likelihood of retakes, directly impacting patient radiation safety and chairside efficiency.</span></p>
