The most common consequence of bleaching non-vital teeth is cervical resorption. This occurs because: 1) Bleaching agents can penetrate through dentinal tubules and reach the cervical area, 2) The agents cause chemical irritation to periodontal ligament cells, 3) This triggers inflammatory resorption at the cervical region, 4) The process can be progressive and lead to tooth loss. Proper isolation with cervical seal using glass ionomer cement helps prevent this complication.

The primary mechanism of H+ secretion by parietal cells is through the action of the H+-K+ ATPase pump, also known as the proton pump. This enzyme is responsible for actively transporting H+ ions into the gastric lumen while moving K+ ions into the cells, thereby acidifying the gastric content.

Radiographic resolution of a periapical lesion (an area of bone loss around the tooth root caused by infection) after proper root canal treatment typically takes time because it involves the biological process of new bone formation to replace the damaged area. This healing process is a gradual one, and while clinical symptoms resolve quickly, visible changes on an X-ray (radiographic resolution) can take several months to become apparent. The 6-12 month timeframe is the established period for significant or complete radiographic evidence of healing in most cases. A longer follow-up period may be needed in some instances.
