EndodonticsSuccess of reimplanted avulsed tooth depends on all the mentioned factors: 1) Proper antibiotic coverage prevents infection that can trigger inflammatory resorption, 2) Prevention of PDL dehydration is crucial - maintaining viable periodontal ligament cells is key to successful reattachment, 3) Protection of socket from trauma and contamination promotes healing. Additional factors include: extraoral time (should be <30 minutes), appropriate storage media (milk, saline), gentle handling of root surface, and prompt professional treatment. All these factors work together to maximize success.

Dental Materials
The first light-activated systems were formulated for UV light to initiate free radicals. Today the UV light-cured composites have been replaced by visible blue-light-activated systems with greatly improved depth of cure, a controllable working time, and other advantages. Because of these advantages, visibly light-activated composites are more widely used than are chemically acti wited materials.

The Bowdler-Henry lateral trephination technique is a surgical method used specifically for the removal of impacted mandibular third molars that are partially formed or deeply embedded. This approach involves accessing the tooth from the side (laterally) of the mandible rather than the top (occlusally).
