b. Liu and Hassan were surprised to find metopic suture on an adult skull because right after birth the left side and right side of the frontal bone are united by the metopic suture. They were surprised because this suture should have disappeared between the ages of six to eight years of age. C. What delicate skeletal structures are found inside the nasal cavity that might be missing from an excavated skull? c. The skeletal structures that are found inside the nasal cavity that might be missing from a excavated skull would be the perpendicular plate, middle and inferior nasal concha and the vomer. D. How would Hassan and his team be able to tell the ages of the skeletal remains of the woman and baby?
The early people who scraped primitive drawings onto cave walls used some of the same tools and techniques that artisans still use today. Since then engraving gave the beginning for the art of inlay! D. Preview: Because the entire history of the art of inlay up to modern times is too extensive i will focus only on three questions: Why did people inlay? what materials and technique do modern artists use for inlay? Transition: Let`s find out why ancient people did inlay.
Endodontic Procedures Endodontic procedures are used in the diagnosis and treatment of oral pain involving the pulp and periradicular area (just outside or around the root of the tooth origin). Pulp therapy, such as pulpotomy, is a common endodontic procedure in which dental pulp is removed from the pulp chamber. The nonsurgical treatment of root canals, especially in difficult cases such as teeth with blocked, narrow or unusually positioned canals, also is a major part of endodontic therapy. Endodontic treatment may also be required for surgical removal of diseased or abnormal (pathologic) tissues, repair procedures associated with the surgical removal of pathologic tissues, repair of cracked teeth or the replacement (replantation) of teeth knocked out (avulsed) by injury. Additional endodontic procedures include: * Surgical removal of tooth structure, such as an apicoectomy, or root-end resection (the removal of the root tip and the surrounding infected tissue of an abscessed tooth), hemisection (the process of cutting a tooth with two roots in half) and bicuspidization (procedure to change tricuspid valve into a functioning bicuspid valve) * Root-end
Overview Dental hygienists work alongside dentists to provide preventative dental care that includes cleaning teeth and teaching patients good hygiene. They also take and develop dental x-rays, apply sealants and, in some states, even place and carve fillings. They can't diagnose diseases, but dental hygienists can prepare clinical and diagnostic tests for the dentist to interpret. Training and Education To become a licensed dental hygienist, applicants must first graduate from an accredited dental hygiene school and pass a written and clinical test. Most states also require an examination on the legal aspects of the practice.
The patient reported dental trauma as the cause of the discoloration which had occured almost 15 years ago. According to the acquired dental history of the patient, an external bleaching procedure had been performed almost a decade ago, with custom-made trays, but the shade rebound lead to a gradual unpleasant outcome. Clinical examination confirmed the vitality of the right central incisor. An external in-office bleaching procedure was initially suggested to the patient, following the philosophy of minimal tooth intervention.The patient refused to follow any re-bleaching treatment. She was determined to have a direct and permanent esthetic solution for her upper front teeth.
Titanium is used here because it can easily form bonds with bones and gums. Before planting the artificial root, it is cleaned thoroughly and space is created by drilling into the gum where the implant is to be done. The artificial root is then placed into the cavity and the process is carried out. As the tissues of the gums heal, the tooth gets fixed at its position and gives the appearance of an original tooth. Generally an implant is done using a titanium screw that is fixed into the gums and then an artificial tooth also known as crown is placed over the screw.
The earliest ancient Egyptian buried their dead in small pits. Then ancient began to put it in coffin to protect them from wild animals in the desert. The Egyptians realized that the body placed in coffins decayed when they were not exposed to the hot, dry sand of the desert. Over many centuries, the ancient Egyptians developed a method of preserving bodies so they would remain life.
The first tool that oral professionals use for caries detection is done visually by using their eyes. The oldest method for detecting the changes within the tooth structure is the microporosity of enamel, which is done with the transmission of light through the enamel. Next, would be color changes within the tooth enamel and dentin followed by defects within the enamel. These all can be detected with the direct vision by the clinician’s eyes or vision associated with a mirror and a standard dental light. In addition, by detecting a small dental defect a small, rounded-end dental explorer or probe can be used (Braga., 2010; Van Dorp., 1988; Ekstrand.,
While out in the bush, a man reportedly saw an apparition of a maiden-Ichtabos- when he stumbled upon the remains while hunting. The original Mayan name for the site translates into “Clay Mountain.” Xunantunich was re-discovered in 1938 and excavation was begun by Thomas Gann, a British medical officer. Gann was reported to have excavated many Mayan artifacts and treasures, however any record of the finds and the artifacts themselves have been lost. Continuous excavation and restoration has been taking place since 1990 by the University of California, Los Angeles under the direction of Dr. Richard Leventhal. Xunantunich is a Classical period ceremonial site, and is thought to have been inhabited from around 300-900 AD.
SPECIAL IMPRESSION PROCEDURE FOR TOOTH-TISSUE SUPPORTED REMOVABLE PARTIAL DENTURES This situation requiring special impression procedure includes not only distal extension partial edentulous situations like Class I and II but also includes long span anterior edentulous ridge (including atleast 6 anterior teeth). Where the ridge must supply some support for the partial denture (Long span Class IV). A tooth supported removable partial denture can be constructed on a master cast made from a single, pressure free impression that records the teeth and the residual ridge in their anatomic form, because here, the denture bas doesn’t contribute to the support of the partial denture much significantly as most of the stress is transmitted through abutment teeth. A dual impression technique is used to equalize as much as possible the support derived from the edentulous ridge and that received from abutment teeth. Tooth is captured in its anatomic form while impression of soft tissue, must be made in such manner as to record the tissues in a functioning form.
