The gene associated with cleft palate in ectodermal dysplasia is the ED1 gene (also known as the EDA gene), which provides instructions for making a protein called ectodysplasin 1. Mutations in this gene can lead to various forms of ectodermal dysplasia, which often include symptoms like missing or abnormal teeth, hair, and sweat glands, and sometimes cleft palate.

EndodonticsInternal resorption is a condition where the dentin and pulp of a tooth are resorbed internally. It is often a result of chronic inflammation of the pulp. Radiographically, it appears as an enlargement of the pulp space, which can give the tooth a pinkish hue clinically (pink tooth of Mummery). The process involves clastic cells that resorb the dental hard tissues.

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.

If the temperature of the water used to mix gypsum products exceeds 50°C, it can slow down the setting reaction due to the reversible nature of the gypsum crystal formation at higher temperatures.
