Abstract:
:Mark Twain provides a humorous and insightful look into the origins of periodontal therapy and anesthesia in "Happy Memories of the Dental Chair". The main character of this story is Dr. John Riggs, the father of periodontics. Dr. Horace Wells, a pioneer in the field of anesthesia, also appears in the story. Twain presents his autobiographical experiences with dentistry in his literary work in a form that can be seen to be similar to a case report in a professional dental journal.

传,历史文章,杂志文章abstract::Sensitivity or pain of the mucoperiosteum covering the mandibular edentulous ridge is often thought to limit bite forces in complete-denture wearers. Therefore, bite forces with mandibular implant-retained overdentures may depend on the degree of implant support. This study analyzed the effects of different degrees of...
