Molar incisor hypomineralisation (MIH) is a type of enamel defect affecting, as the name suggests, the first molars and incisors in the permanent dentition. [1] MIH is considered a worldwide problem with a global prevalence of 12.9% and is usually identified in children under 10 years old. [2]
Non-dental causes of toothache are much less common as compared with dental causes. In a toothache of neurovascular origin, pain is reported in the teeth in conjunction with a migraine. Local and distant structures (such as ear, brain, carotid artery, or heart) can also refer pain to the teeth.
Pericoronitis is inflammation of the soft tissues surrounding the crown of a partially erupted tooth, [1] including the gingiva (gums) and the dental follicle. [2] The soft tissue covering a partially erupted tooth is known as an operculum, an area which can be difficult to access with normal oral hygiene methods.
The inflammation of the pulp is a side effect of the immune response and causes pain. [10] 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.
Odontogenic infections can be severe if not treated and are associated with mortality rate of 10 to 40%. [4] Furthermore, about 70% of odontogenic infections occur as periapical inflammation, i.e. acute periapical periodontitis or a periapical abscess. [3] The next most common form of odontogenic infection is the periodontal abscess. [3]
The two main classification systems are described below. Others include the tooth surface fluorosis index (Horowitz et al. 1984), which combines Deans index and the TF index; and the fluorosis risk index (Pendrys 1990), which is intended to define the time at which fluoride exposure occurs, and relates fluorosis risk with tooth development stage.
The mandibular central incisors are the first primary teeth to erupt, usually between 6 and 10 months of age and usually causes discomfort and pain to the infant. [1] It can take several years for all 20 teeth to complete the tooth eruption. Though the process of teething is sometimes referred to as "cutting teeth", when teeth emerge through ...
Acid erosion is a type of tooth wear.It is defined as the irreversible loss of tooth structure due to chemical dissolution by acids not of bacterial origin. [1] Dental erosion is the most common chronic condition of children ages 5–17, [2] although it is only relatively recently that it has been recognised as a dental health problem. [3]
