31 results about "Dental extraction" patented technology

A dental extraction (also referred to as tooth extraction, exodontia, exodontics, or informally, tooth pulling) is the removal of teeth from the dental alveolus (socket) in the alveolar bone. Extractions are performed for a wide variety of reasons, but most commonly to remove teeth which have become unrestorable through tooth decay, periodontal disease, or dental trauma, especially when they are associated with toothache. Sometimes wisdom teeth are impacted (stuck and unable to grow normally into the mouth) and may cause recurrent infections of the gum (pericoronitis). In orthodontics if the teeth are crowded, sound teeth may be extracted (often bicuspids) to create space so the rest of the teeth can be straightened.

Root canal filler and dental tissue regeneration method

Provided is a novel and creative dental tissue regeneration method for regenerating dental tissue after pulpectomy or the enlargement and cleaning of an infected root canal. After pulpectomy or the enlargement and cleaning of an infected root canal, a root canal filler (200) having an extracellular matrix (210) containing the cells (220) enriched for dental pulp stem cells, is inserted into the apical side of the root canal of a target tooth (100). The cells including dental pulp stem cells include at least one of the following: dental pulp SP cells, CD31-negative and CD146-negative cells, CD24-positive cells, CD105-positive cells, and CD150-positive cells. For instance, dental pulp SP cells are CD31− and CD146− negative. Even if pulpitis due to deep caries occurs, appropriate dental pulp regeneration and recovery of dental pulp function are possible.
