Pulpotomy is a minimally invasive procedure performed in children on a primary tooth with extensive caries but without evidence of root pathology. [1] The minimally invasive , endodontic techniques of vital pulp therapy (VPT) are based on improved understanding of the capacity of pulp tissues to heal and regenerate plus the availability of ...
Two different types of pulp cap are distinguished. In direct pulp capping, the protective dressing is placed directly over an exposed pulp; and in indirect pulp capping, a thin layer of softened dentin, that if removed would expose the pulp, is left in place and the protective dressing is placed on top. [4]
The ear cartilage lying beneath the implants is either left intact or is scored or perforated with a needle - the latter is done to weaken it. The patient is allowed to check the new position of his ears in a mirror before the operation by having a Prefold positioner, of the same size, shape and tension as the implant, placed temporarily on the ...
The types of endodontic therapy which may be undertaken are either a pulpotomy or a root canal treatment; [6] other than restorability, the option chosen depends on a number of factors including how far the tooth is from root completion, the extent of pulpal involvement and whether it is a primary or permanent tooth.
Tympanic membrane retraction describes a condition in which a part of the eardrum lies deeper within the ear than its normal position.. The eardrum comprises two parts: the pars tensa, which is the main part of the eardrum, and the pars flaccida, which is a smaller part of the eardrum located above the pars tensa.
Tympanoplasty can be performed through the ear canal (transcanal approach), through an incision in the ear (endaural approach) or through an incision behind the ear (postauricular approach). A graft may be taken to reconstruct the tympanic membrane.
Stapedectomy is performed under either local or general anesthesia depending on the preference of the surgeon. [6] Most surgeons do not make any skin incisions, especially when the surgery is performed with an endoscope. [9] However, sometimes the ear canal is so small that an incision is needed. [9]
Otoplasty (surgery of the ear) was developed in ancient India and is described in the medical compendium, the Sushruta Samhita (Sushruta's Compendium, c. 500 AD).The book discussed otoplastic and other plastic surgery techniques and procedures for correcting, repairing and reconstructing ears, noses, lips, and genitalia that were amputated as criminal, religious, and military punishments.
