Dental concrescence

BACKGROUND: Double teeth are dental anomalies that can lead to aesthetic and orthodontic problems. CASE PRESENTATION: This report discusses two cases involving the multidisciplinary management of permanent maxillary left lateral incisors fused with a supernumerary tooth in two girls aged 9 and 10. Following intraoral and radiographic examinations, one was diagnosed with fusion, and the other was diagnosed with concrescence. The crown of the fused incisor was separated using a burs and extracted intraorally...

AIM: The aim of this paper is to report a rare case in a 6-year-old girl where two dental anomalies, fusion and concrescence, coexisted in primary dentition. This highlights the significance of the accurate early diagnosis of these dental anomalies. BACKGROUND: Odontogenic anomalies are frequently encountered in dental practice. These anomalies can occur due to abnormalities during the differentiation stage and may lead to aberrations in hard tissue formation. Some of the uncommon and unusual dental anomalies of number and form include fusion, gemination, and concrescence...

Developmental disturbances in the permanent dentition are commonly seen due to traumatic injuries to the primary teeth, especially intrusive and avulsion injuries of the overlaying primary incisors. These disturbances may range from enamel discoloration or hypoplasia, crown/root dilaceration, odontoma-like malformation and eruption disturbances. Concrescence is extremely rare in anterior teeth. This case report describes a rare case that showed a concrescence of the unerupted maxillary right lateral incisor and maxillary central incisor with crown dilaceration...

OBJECTIVES: This paper aims to better define hypercementosis, investigate its described potential aetiologies, and determine whether there are different patterns of cementum apposition and if they are a function of their supposed aetiology. DESIGN: A literature review was undertaken using the Medline, DOSS, Scopus and Cochrane Library electronic databases. Two co-authors selected the published works independently, extracted the data in accordance with the PRISMA statement...

BACKGROUND: Morphological anomalies of teeth, including talon cusp, dens evaginatus, gemination, fusion, concrescence, root dilaceration, and taurodontism, always involve changes in the enamel, cementum and dentin. Diagnosing concrescent teeth through routine clinical examination alone is difficult, and most cases of concrescence are found accidentally during extraction. A definite preoperative diagnosis of concrescence would contribute to a better treatment plan and fewer undesirable complications...

Double tooth pathologies are important indicators of trauma, disease, diet, and feeding biomechanics, and are widely documented in mammals. However, diagnosis of double tooth pathologies in extinct non-mammalian vertebrates is complicated by several compounding factors including: a lack of shared terminology reflecting shared etiology, inconsistencies in definitions and key features within and outside of mammals ( e.g ., gemination, fusion, twinning, concrescence); differences in tooth morphology, heterodonty, regeneration, and implantation between mammals and non-mammalian vertebrates; and the unmet need for diagnostic criteria that can be applied to isolated teeth, which are common in the fossil record...

OBJECTIVE: The aim of this study was to investigate the prevalence of dental anomalies in the Eastern Province of Saudi Arabia using the digital Orthopantomography (OPG). METHODS: A retrospective radiographic study was performed in which digital OPGs of 1189 subjects, ages ranging between 7 and 65 years were reviewed, and 1104 fulfilled inclusion criteria. Statistical analysis was performed. The OPGs were reviewed for congenitally missing teeth, impactions, ectopic eruption, supernumerary teeth, odontomas, dilacerations, taurodontism, dens in dente, gemination and fusion...

AIM AND OBJECTIVE: The aim and objective of this study was to review the literature to analyze the prevalence of developmental dental anomalies regarding shape in India. BACKGROUND: Although there have been several studies investigating the prevalence of individual dental anomalies related to shape, only a few studies considered all subtypes and their distribution among genders, especially in India. RESULTS: An electronic search was made in the PUBMED database to review prevalence-based data on developmental dental anomalies related to shape in India up to December 2018...

AIM: The aim of this paper is to report a rare case in which two dental anomalies in primary dentition coexisted-fusion and concrescence in a 4-year-old boy. This highlights the significance of the accurate early diagnosis of these dental anomalies. BACKGROUND: Odontogenic anomalies are frequently encountered in dental practice. These anomalies can occur due to abnormalities during the differentiation stage and lead to abnormalities in the hard tissue formation...

Dental abnormalities in archeological material such us concrescence or odontoma are rare cases often found accidentally, mostly during routine X-ray analysis or during macroscopic examination of the mastication apparatus. In this study, we present a rare case of concrescence between an upper left third molar and a supernumerary fourth molar in a 19th century skull from Uganda. Simultaneously, it is a critical revision of earlier studies on the same object (which considered this abnormality as an odontoma), using dental X-ray imaging and histological analysis...

Dental concrescence is a rare dental abnormality resulting in the joining of two teeth at the level of the cementum. This is the first reported case of the orthodontic management of a dental concrescence and the options for patient treatment are discussed. In this case, a compromised occlusal result was accepted with restorative masking of the affected teeth.

Down syndrome is one of the most common congenital anomaly. It is most frequently caused by trisomy of chromosome 21. Other causes can be mosaicism and translocation. Such patients are commonly encountered in routine dental practice. This syndrome has wide range of medical and dental abnormalities. This paper presents a unique case of fusion and concrescence of retained primary teeth in a child with Down syndrome. The incidence of such anomalies is quite low in these cases. Thus, a better awareness of such conditions on part of a dental practitioner will aid in the provision of enhanced dental care to these patients...

Concrescence is a form of twinning, formed by the confluence of cementum of two teeth at the root level. The diagnosis of concrescence has largely relied on the conventional 2D imaging. The 2D imaging has inherent limitations such as distortion and superimposition. Cone-Beam CT eliminates these limitations. The aim of this article was to describe a case of dental abnormality using Cone-Beam CT imaging modality. Volumetric data demonstrated confluence of left mandibular third molar with a paramolar, a supernumerary tooth...

Concrescence is a rare dental anomaly whereby adjacent teeth are united by cementum. It has been reported to occur in around 0.8% of permanent dental extractions and a correct diagnosis prior to surgical intervention is important to ensure that patients can make an informed decision about their treatment and to reduce the potential for dentolegal action against the responsible clinician. An 83-year-old woman was referred to the Oral and Maxillofacial Surgery Department at the Wirral University Teaching Hospital, for extraction of her upper left first molar tooth...

Fusion is an anomaly manifested in both deciduous and permanent dentitions. Fusion of dental tissues in the primary dentition is of clinical significance owing to the challenges in treatment of the affected teeth and aberrations encountered in development and eruption of their successors. Triple tooth refers to the union of three separate tooth entities. It can occur by fusion, germination, concrescence or a combination of both fusion and germination. Triplication is rarely encountered in the deciduous dentition...

Supernumerary teeth in the molar area are classified as paramolars or distomolars based on location. They occur frequently in the maxilla, but only rarely in the mandible. These teeth are frequently fused with adjacent teeth. When this occurs, the pulp cavities may also be connected. This makes diagnosis and planning of endodontic treatment extremely difficult. Here we report a case of a mandibular second molar fused with a paramolar, necessitating dental pulp treatment. Intraoral and panoramic radiographs were obtained for an evaluation and diagnosis...

The aim of this article was to describe imaging aspects of concrescence analyzed by three imaging modalities. A second molar joined together with a third molar was imaged using digital periapical radiography, cone beam computed tomography (CBCT) and micro-computed tomography (Micro-CT). On periapical radiograph, the mesial root of the third molar is superimposed on the distal root of the second molar. On CBCT images, a large cementum union between bulbous roots was detected, confirming the diagnosis of concrescence...

Dental anomalies of number and forms may occur in the primary and permanent dentition. Various terms have been used to describe dental twinning anomalies: Germination, fusion, concrescence, double teeth, conjoined teeth, twinned teeth, geminifusion, and vicinifusion. Fused tooth is a developmental anomaly that is seen more frequently in the primary than the permanent dentition. Double tooth involving deciduous anterior teeth is found mostly in the mandible. Very few cases of nonsyndromic double primary molar have been reported in the literature...

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. There is a slight predilection for the mandible especially in the premolar area followed by the molar and anterior regions. Awareness of these developmental disturbances with proper diagnosis and treatment is very essential because it can compromise the periodontal attachment and can lead to the tooth loss...

Odontogenesis is a complex process wherein more than 200 genes are known to play a significant role in tooth development. An imbalance can lead to an abnormality in the number, size, shape or structure of the developing tooth/teeth. The presence of an extra dental lamina forms a supernumerary tooth. The supernumerary teeth are of two types: A rudimentary tooth where the supernumerary tooth does not resemble any tooth in the normal series or a supplemental tooth in which this anomalous tooth resembles one in the normal series...
