What is concrescence in dentistry?
Concrescence is a developmental anomaly of dental hard tissues. It is a condition showing union of adjacent teeth by cementum. The concrescence leads to a loss of gingival architecture leading to the development of funnels, which may cause plaque accumulation thus, resulting in periodontal tissue destruction.
What causes concrescence?
Cause. This condition arises as the result of traumatic injury or overcrowding of teeth. True concrescence occurs during root formation phase, whereas acquired concrescence occurs after the radicular phase of development is complete.
What is the difference between fusion and gemination?
Fusion is the union of two embryologically separate developing teeth. Gemination is the incomplete division of a single tooth bud.
Which teeth are most commonly affected by gemination?
Gemination is more frequent in the anterior teeth, although it can also affect molars and bicuspids.
What is tooth fusion?
Fusion is a dental anomaly that arises through the union of two adjacent teeth. The case report presents multidisciplinary management of a fused maxillary anterior tooth.
What is gemination linguistics?
In phonetics and phonology, gemination (/ˌdʒɛm-/), or consonant lengthening (from Latin geminatio ‘doubling’, itself from gemini ‘twins’), is an articulation of a consonant for a longer period of time than that of a singleton consonant.
Are fused teeth common?
Fusion is a rare developmental disorder characterized by the union of two adjacent teeth at the crown level (enamel and dentin), causing the formation of a tooth with an enlarged clinical crown. Incidence of this anomaly is approximately 0.1% in the permanent and 0.5% in the primary dentition.
How is tooth fusion treated?
Management of fused teeth usually requires a multidisciplinary approach. Surgical, endodontic, orthodontic, and restorative interventions are usually proposed in combination to manage fused teeth.
What is gemination phonetics?
ABSTRACT: Gemination is a phonetic phenomenon whereby two identical /sounds/ co-occur in one word or at words boundaries. The co-occurrence of two identical sounds doesn’t matter, what matters is their pronunciation.
What’s the difference between a fusion and a gemination?
Gemination is a single enlarged tooth in which the tooth count is normal when the anomalous tooth is counted as one. Fusion is the combining of two tooth germs to form an enlarged tooth. Here the tooth count is one less, when the anomalous tooth is counted as one.
How is gemination used in the dental field?
In dental context, gemination refers to a developmental irregularity in which a single tooth germ divides resulting in a bifid crown on a single root, that is, two teeth develop together from a single tooth bud. The two parts of the double tooth will be exact images of each other.
What is the difference between Concrescence and fusion?
In geminated teeth, division is usually incomplete and results in a large tooth crown that has a single root and a single canal. Both gemination and fusion are prevalent in primary dentition, with incisors being more affected. Concrescence is a condition of teeth where the cementum overlying the roots of at least two teeth join together.
What causes gemination in the upper incisor of a tooth?
They most frequently occur in the primary upper incisors. Cause. The main cause of gemination is unknown, but these factors have been put forward as possible reasons. Vitamin deficiency. Hormonal irregularities. Any type of infection or inflammation near the tooth bud during the time of tooth development.
