Definitions of macroglossia have been proposed, including "a tongue that protrudes beyond the teeth during [the] resting posture" and "if there is an impression of a tooth on the lingual border when the patients slightly open their mouths". [5] Others have suggested there is no objective definition of what constitutes macroglossia. [14]
The formation of teeth begins during embryonic development and is a process that is highly regulated by various signaling pathways, which, if disrupted as a result of genetic mutations or environmental factors, can lead to developmental anomalies, including hyperdontia. Tooth development begins with the formation of tooth buds in the jaw.
This loss of support for the teeth is essentially irreversible damage. Chronic periodontitis is generally slow to moderate in terms of disease progression, although short bursts of increased tissue destruction may occur. Ultimately, tooth loss may occur if the condition is not halted. It is termed localized when less than 30% of sites around ...
Macrodontia is not a lethal disease, rather, it is a disorder which affects the physical appearance of the teeth and can have implications with the surrounding teeth, thereby affecting the overall positioning of the teeth, jaw pain, and other crowding issues resulting in future misalignment.
Crenated tongue is usually asymptomatic and harmless. [3] It is not a disease as such, but usually results from habits where the tongue is pressed against the lingual surfaces (the side facing the tongue) of the dental arches, or from any cause of macroglossia (enlarged tongue), [3] which in itself has many causes such as Down syndrome.
Males tend to have larger teeth than females, [1] and tooth size also varies by race. [1] Abnormal tooth size is defined by some as when the dimensions are more than 2 standard deviations from the average. [1] Microdontia is when the teeth are abnormally small, and macrodontia is when the teeth are abnormally large.
Brushing teeth too hard can wear down the enamel, aka the protective layer on your teeth. (Photo illustration: Jay Sprogell for Yahoo News; photo: Getty Images) (Photo illustration: Jay Sprogell ...
The tongue's upper surface (dorsum) is covered by taste buds housed in numerous lingual papillae. It is sensitive and kept moist by saliva and is richly supplied with nerves and blood vessels. The tongue also serves as a natural means of cleaning the teeth. [2] A major function of the tongue is to enable speech in humans and vocalization in ...
