Tongue thrusting is a type of orofacial myofunctional disorder, which is defined as habitual resting or thrusting the tongue forward and/or sideways against or between the teeth while swallowing, chewing, resting, or speaking. Abnormal swallowing patterns push the upper teeth forward and away from the upper alveolar processes and cause open bites.
Anodontia is the congenital absence of teeth and can occur in some or all teeth; whereas partial anodontia (or hypodontia), involves two dentitions or only teeth of the permanent dentition (Dorland's 1998). Approximately 1% of the population has oligodontia. [1]
Non-carious cervical loss due to abrasion may lead to consequences and symptoms such as increased tooth sensitivity to hot and cold, increased plaque trapping which will result in caries and periodontal disease, and difficulty of dental appliances such as retainers or dentures engaging the tooth.
Each tooth that may be painful is percussed (tapped), palpated at the base of the root, and probed with a dental explorer for dental caries and a periodontal probe for periodontitis, then wiggled for mobility. [10]: 10 Sometimes the symptoms reported in the history are misleading and point the examiner to the wrong area of the mouth.
Signs and symptoms of temporomandibular joint disorder vary in their presentation. The symptoms will usually involve more than one of the various components of the masticatory system, muscles, nerves, tendons, ligaments, bones, connective tissue, or the teeth. [23] The three classically described, cardinal signs and symptoms of TMD are: [11] [24]
Pulpitis can often create so much pressure on the tooth nerve that the individual will have trouble locating the source of the pain, confusing it with neighboring teeth, called referred pain. The pulp cavity inherently provides the body with an immune system response challenge, which makes it very difficult for a bacterial infection to be ...
Axenfeld–Rieger syndrome is a rare autosomal dominant [2] disorder, which affects the development of the teeth, eyes, and abdominal region. [3]Axenfeld–Rieger syndrome is part of the so-called iridocorneal or anterior segment dysgenesis syndromes, [4] which were formerly known as anterior segment cleavage syndromes, anterior chamber segmentation syndromes or mesodermal dysgenesis.
The inferior alveolar nerve to anaesthetise all of the teeth in the mandibular arch; The long buccal nerve which supplies the soft tissue buccally to the mandibular molars; The lingual nerve which anaesthetising stops sensation to the lingual aspect of the gingiva, floor of the mouth and the tongue to the midline on that particular side
