Other studies have tried to determine the relationship between the mandibular symphysis, some have seen that disturbances to its morphology and growth pattern can cause hypodontia while others show hypodontia can change the morphology of the mandibular symphysis. The aetiology of hypodontia can be multi-factorial with different factors playing a role. The mechanism of how these factors act is still uncertain but ultimately they cause hypodontia due to either: 1.physical obstruction or disruption of the dental lamina 2.space limitation 3.functional abnormalities of the dental epithelium 4.failure of initiation of the underlying mesenchyme. (Nunn et al., 2003) Hypodontia affecting teeth in the anterior region poses various physical and emotional problems. These include altered facial appearance, malocclusion, difficulty in mastication and speech (Nunn et al., 2003), delayed primary tooth exfoliation (Neville et al, 2013).
Experiences of pain lead to anxiety for both patient and clinician before and after root canal treatment. Pain is not always associated with sensation to noxious stimuli but also associated with the individual experiences, anxiety, stress, expectations and personality. Though the pain may not be a sign of endodontic failure, relieving pain is of utmost importance for the acceptance of endodontic procedure. Postoperative endodontic pain continues to be a significant problem facing the dental profession (Liesinger, Marshall & Marshall 1993). Up to 80% of endodontic patients who report with preoperative pain continue to experience some level of pain following the endodontic procedure (Marshall 2002).
A root canal is a procedure that is performed when you have a pulp-filled cavity that is located in the root of a specific tooth in your mouth. Here are three things you need to know about getting a root canal that your dentist may not tell you. #1 Lessen Pain By Getting Treated Right Away If you want to reduce the pain of going through a root canal procedure, it helps to get treated right away. As soon as you notice that a tooth is aching, you should go in and have it looked at by your dentist. If you wait until your tooth is swollen, it is going to be more painful to go through the root canal procedure.
4.2. TMDs related to Disc Derangements A disc derangement is defined as a displaced disc relative to the condyle and eminence of the temporal bone (5,9,12). Displacement of the disc affects the functional joint movement, can cause movement limitation and gives problems with functional jaw activities such as chewing, mouth opening, yawning, talking, smiling, singing and brushing teeth (92). Many etiologic factors have been suggested to explain disc derangements (93-99). Direct or indirect trauma to the jaw may cause stretching, tearing, or rupture of the disc, lateral ligament, or capsule.
If the lesion is not completely excisional, the result can be a recurrence and possible additional bone destruction by its evolution, leading to periodontal defects and additional tooth loss (KENDRICK F; WAGGONERW. F, 1996). The objective of this study is to describe a case of jaw injury diagnosed as peripheral ossifying fibroma and confront with data from the current
They are often mobile due to their incomplete root formation. If natal teeth are of diagnosed as part of normal dentition, they should be retained in the mouth. However, extraction is indicated when complications arise. Complications associated with these prematurely erupted teeth are interference with breast milk sucking, ulceration on the ventral surface of the tongue caused by the sharp edges of the tooth, aspiration of dislodged teeth, and traumatic injury to the mother’s breast. These situations would indicate removal of natal teeth.
The maxilla, post-extraction of the teeth tends to consists of thin cortices and spongy cancellous compartments. The advanced resorption of alveolar bone combined with a poor quality of bone found in the posterior maxilla creates a situation which is not conducive to higher clinical success with dental implants. As a consequence of this, placement of short implants in poor quality bone is not advisable as shorter implants when placed in maxilla may take a longer time to heal and may not reciprocate the same way as in the mandible. Jemt and Lekholm et al. (1995) 107 reported a failure rate of 24% with implants of height ≤
9.8 Cognitive restructuring Extreme or negative thinking has been found to contribute to increase anxiety as unhelpful thinking styles undermine an individual’s perceived ability to cope with a situation. Unhelpful thinking style may include extreme or catastrophic thinking about the dental encounter/procedure (e.g. I might ‘choke’ ) or mind reading and jumping to conclusions(e.g. ‘the dentist won’t understand my phobia and will think I am silly’). Cognitive restructuring refers to a child being taught to recognize the negative thoughts which precipitate their anxiety and replace these with more helpful cognitions.
Periodontal diseases:- Periodontitis is a chronic multifactorial inflammatory disorder induced by microorganisms and defined by progressive damage of the tooth supporting tissues leading to tooth loss. This is to be recognized from gingivitis which is a reversible inflammatory reaction. Periodontitis is a main public health dilemma because it is common, it decrease quality of life, it decrease chewing purpose and hurt aesthetics, and finally results in tooth loss and disability. Periodontitis starts with a microbial contagion, accompany by a host-mediated damage of soft tissue induce by hyperactivated or primed leukocytes and the production of cytokines, eicosanoids, and matrix metalloproteinases that induce clinically notable connective tissue and bone damage. Bacterial collection on the teeth is necessary to the induction and progress of periodontitis.
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
How to evaluate the cost of the procedure for dentures People need to replace the missing teeth with complete denture. This is done even if you have no teeth remaining or have lost several teeth. What is the need of denture is a query? Actually the loss of teeth results in diseases of the gum or tooth decay. You may also suffer from traumatic injury.
