denture Distal end removable partial denture can rotate in function when occlusal force is directed on the denture base. The denture will rotated in vary degree due to different displacement of its supporting structure such as periodontal ligament, mucosa covering residual ridge. The volume of rotation of distal-extension removable partial denture based on quality of the residual ridge, the type and accuracy of the impression, the accuracy of the denture base, placement of supportive, reciprocal, and retentive element to resist
Chronic Periodontitis is an inflammatory disease of the supporting tissues of the teeth caused by specific microorganisms or groups of specific microorganisms, leading to progressive destruction of the attachment apparatus of the teeth including periodontal ligament, cementum and alveolar bone with periodontal pocket formation, and recession of the gingival tissue(1) . The clinical feature that characterizes periodontitis from gingivitis is the presence of clinically apparent attachment loss. This loss mainly is associated with changes in the density and height of subjacent alveolar bone (1). Severe generalized periodontitis affects 5–15% of any population worldwide and is a major cause of teeth loss after dental caries (2).
When most people talk about wisdom teeth, they are often relating a painful or disturbing story from their young adult years, according to Lennox Lin. His Brighton Dental Associates office deals with many patients each year who have wisdom tooth trouble. Wisdom teeth, the third and last set of molars to grow into the mouth, do not emerge until you are a young adult. For some patients, they may start to appear as early as seventeen years old, for others they do not come up until you are well into your twenties. Then again, there are some patients who never have this set of teeth. Though there are four places within the mouth at the back where these teeth would live, some patients only develop
Teeth come in different shapes and sizes and everyones ' teeth are different. However all teeth have a few things in common- they all have three main layers; Enamel, Dentin, and Pulp. Enamel is the very hard protective shell on the visible part or crown of your tooth. It can withstand chewing and biting but is brittle and can chip/break easily. Dentin consists of a substance that is similar to bone, it is underneath the enamel and gives your teeth their color. Last is pulp, pulp is inside of the pulp cavity beneath dentin. Pulp is made of nerves, blood vessels, and connective tissue. Pulp gives your teeth the nutrients they need to live and not fall out or get infected.
(Hajishengallis,2014). Gingivitis, which comes before periodontitis, is an inflammation of the gums. The development of plaque from bacteria causes the gums to swell. This doesn 't bring about quick harm to the bones and tissues, however it results in disturbance of the gums. Following untreated gingivitis is periodontitis (Hajishengallis,2014). Periodontitis is the predominant damage of the periodontium, which can be the supporting tissues and bones of the teeth. This advanced form of gingivitis is also resulting from a microorganism that remains inside the mouth, which brought about infection as properly. The signs and symptoms of periodontal disease can range from a simple gum infection to fundamental harm of the the helping functions of the teeth
Since the early 1900’s it has been well known that soft drinks are particularly bad for your teeth, causing enamel erosion leading to dental caries if left untreated (McCay and Will, 1949).
This technology made a very important impact on us. It changed the way our history developed. It is a technology so pervasive, so invisible, that we, for a long time, forgot to consider it when we talked about human evolution. He then asks everyone to turn and look at each other and give a big smile. He asks, “Do you see any canine teeth, any Dracula teeth”. Everyone laughs and he says, “No of course you do not”. The reason you do not see any canine teeth is that our dental anatomy is actually made, not for tearing down raw meat from bones or chewing fibrous leaves for hours. It is made for a diet, which is soft, mushy, which is reduced in fibers, which is very easily chewable and digestible.
Gingivitis is said to be defined as a mild and common type of gum disease (periodontal disease) which causes irritation, redness and swelling (inflammation) into your gingiva, which is the part of gum around the base of teeth. It should be taken as a serious disease and should be treated immediately. It can further lead to much more serious gum disease known as Periodontitis and also may cause tooth loss.
A study by Addy et al 1999 showed the prevalence of recession to be higher on upper canine and first pre-molar teeth and lower canine, first premolar and incisor teeth, in a group of 92 subjects with a mean age of 35 years.13 Some studies show that the prevalence of gingival recession is higher on the left side of the jaw.14 Higher levels of recession have been found in males than females and in Afrocarribeans and African-american than White Caucasians and other racial or ethnic groups.15 Recession is also found in patients with good oral hygiene as well as in patients with poor oral hygiene. In patients with good oral hygiene, recession is located commonly on buccal surfaces and in those with poor oral hygiene other tooth surfaces are also affected.16,17 Studies also show a correlation between calculus and gingival recession. One such study by Van der Weijden et al 1998 shows a higher prevalence of recession on lingual surfaces of lower anterior teeth in the age group of 20-34 years.18 Habits such as lip and tongue piercings are associated with increased prevalence of recession in mandibular anterior teeth.19 In patients with periodontitis attachment loss, bone loss and gingival recession is located mainly interdentally. It has been estimated that approximately 60%
Environmental factors: Major environmental factors such as infection of the tooth bud or trauma can also be associated with hypodontia. Somatic diseases such as syphilis, scarlet fever and rickets are also associated with hypodontia, as are nutritional disturbances during pregnancy or infancy. Smoking during pregnancy and maternal medications could lead to dental
According to the official guidelines of American Academy of Periodontology, the goals of periodontal therapy are to preserve natural dentition; to maintain and improve health, comfort, esthetics and function; and to provide replacements (i.e., dental implants) where indicated1.Several treatment modalities to achieve these goals are available in periodontics, and they can be broadly classified into either surgical or non surgical approaches. Non surgical approaches include plaque control, supra and sub gingival scaling, root planing and the adjunctive use of chemotherapeutic agents. Non surgical therapy aims to eliminate both living bacteria in the biofilm and calcified biofilm microorganisms from tooth surface and adjacent soft tissues. A reduction in inflammation of the periodontium due to a lesser bacterial load leads to beneficial clinical changes .In addition, non-surgical therapy aims to create an environment in which the host can more effectively prevent pathogenic microbial recolonization using personal oral hygiene
This overall appearance gives a faint radiolucent image hence commonly termed as "Ghost teeth". The other terminologies for RO are Odontogenic dysplasia, Localized arrest tooth development, Unilateral dental malformation, Odontogenesis imperfect and Familial amelodentinal dysplasia.2 The etiology of RO remains unclear however numerous factors like local trauma, teratogenic drugs, Rh incompatability, neural damage, nutritional and vitamin defeciency etc have been considered. The maxilla is affected twice as often as the mandible. It is usually unilateral but rarely bilateral & rarely crosses the midline. Females are affected more often than males (1.4:1).3 This is an interesting case reportof bilateral mandibular involvement, a feature that is rarely reported in
The loss of posterior molars as a result of periodontal or endodontic infection leads to migration of teeth, collapse of the arch, supra eruption of opposing teeth, loss of supporting
Periodontitis is a chronic inflammatory disease of the supporting tissues surrounding the teeth and can result in destruction of the periodontal ligament, cementum, connective tissue and alveolar bone (1). It is a major oral health problem in both developed and developing countries. It exhibits a wide range of clinical, immunological and microbiological manifestations. It is characterized clinically by gingival inflammation, bleeding on probing (BOP) from gingival pockets, increased periodontal pocket depth, loss of clinical attachment level, recession of the gingival margin, alveolar bone loss, increased tooth mobility, drifting and eventually tooth loss. This often leads to compromised function and aesthetics, and may be associated with pain and discomfort (2). In addition, periodontal disease has been associated with systemic diseases and conditions such as cardiovascular
The contour of the marginal ridge as well as overhanging restorations play an important part in survival (Loomans, Roeters, Opdam, & Kuijs, 2008) of the filling and periodontal health (Than, Duguid, & McKendrick, 1982).
