Tooth remineralization is the natural repair process for non-cavitated tooth lesions, [1] [2] in which calcium, phosphate and sometimes fluoride ions are deposited into crystal voids in demineralised enamel. Remineralization can contribute towards restoring strength and function within tooth structure.
Bottom teeth of a seven-year-old, showing primary teeth (left), a lost primary tooth (middle), and a permanent tooth (right) Tooth eruption in humans is a process in tooth development in which the teeth enter the mouth and become visible. Current research indicates that the periodontal ligaments play an important role in tooth eruption.
A tooth needs a supplemental 3 years after eruption to complete the root formation and mark the end of tooth development. Early loss of young immature permanent teeth can be detrimental, leading to loss of function and interference of phonetics. Maxillary and mandibular bone development may be altered, especially when the patient is still growing.
Composites and amalgam are used mainly for direct restoration. Composites can be made of color matching the tooth, and the surface can be polished after the filling procedure has been completed. Amalgam fillings expand with age, possibly cracking the tooth and requiring repair and filling replacement, but chance of leakage of filling is less.
Consequently, enamel, unlike many other tissues of the body, has no way to regenerate itself. [17] After destruction of enamel from decay or injury, neither the body nor a dentist can restore the enamel tissue. Enamel can be affected further by non-pathologic processes. Enamel is covered by various structures in relation to the development of ...
A specialist can often re-treat failing root canals, and these teeth will then heal, often years after the initial root canal procedure. [ citation needed ] The survival or functionality of the endodontically treated tooth is often the most important aspect of the endodontic treatment outcomes, rather than its apical healing alone. [ 48 ]
The GBR principle was first examined by Dahlin et al. in 1988 on rats. The selective ingrowth of bone-forming cells into a bone defect region could be improved if the adjacent tissue is kept away with a membrane; this was confirmed in a study by Kostopoulos and Karring in 1994. GBR can be used for bone regeneration on exposed implant coils . [4]
An OAC can happen for many other more unusual reasons, such as acute or chronic inflammatory lesions around the tip of a tooth root which is in close proximity with the maxillary antrum, destructive lesions/tumors of the maxilla, failure of surgical incisions to heal (e.g. Caldwell-luc antrostomy), osteomyelitis of the maxilla, careless use of ...
