ABSTRACT
Dental fusion is defined as an abnormality in tooth shape caused by developmental tooth disturbances that produce an intimate union of dental tissues. This case report discusses treatment of a mandibular impacted "double" third molar in a 21-year-old patient that could have been related to either gemination or tooth fusion. Radiological examination allowed for careful analysis of the tooth's shape and root development, relation to the inferior alveolar nerve, and 3-dimensional position. After evaluation of therapeutic options and risks, and with the patient's consent, the authors opted to extract the tooth in question. Such favorable conditions as the incomplete development of the roots and the relatively young age of the patient, combined with the use of an antibiotic and antiseptic prophylaxis as well as a standard surgical approach, enabled a successful result to be achieved with no related complications.

Fused teeth were a phenomena of teeth anomalies in shape, which can affect the dental teeth both in primary and permanent dentition. Fused teeth do not only cause problems on crowding of dentition, abnormal occlusion and aesthetic, but also increase risks of dental caries, endodontics diseases, periapical diseases and periodontal diseases. Fusion of deciduous teeth may lead to abnormality of subsequent permanent teeth. Treatment of fused teeth may require multidisciplinary approach in endodontics, periodontics, oral and maxillofacial surgery, prosthodontics and orthodontics. The aim of the present article is to review the etiology, classification, clinical manifestations and treatment of fused teeth in order to provide dental clinicians with a reference of clinical management for fused teeth.

OBJECTIVE: To report a conservative treatment of a rare developmental anomaly. CASE REPORT: A 73-year-old patient with previously initiated therapy and acute apical abscess of a maxillary right central incisor fused with the supernumerary tooth sought treatment. The conservative approach included nonsurgical root canal treatment and composite restoration. CONCLUSION: This case illustrates the importance of an individual approach when treating anomalous teeth. Priorities in pain and infection management to properly and functionally restore teeth should be unaffected by age.

AIM: The purpose of this report is to present a case of endodontic management of a dilacerated maxillary central incisor fused to supernumerary tooth unusually appearing as a labial tubercle using cone beam computed tomography (CBCT) as a diagnostic aid. BACKGROUND: Anterior teeth are commonly encountered with aberrant anatomical variations in the crown, number of roots, and root canals. Fusion is an infrequent developmental abnormality in shape of the tooth caused by the union of two adjacent tooth germs. A complete knowledge of such complex anatomies is mandatory for a successful root canal treatment. It highlights the endodontic and restorative approach in the functional and esthetic rehabilitation of the involved tooth. CASE REPORT: Three-dimensional imaging using CBCT was used in this case to differentiate single labial canal and palatal C-shaped canal. The endodontic treatment was performed with the aid of dental operating microscope, and the root canals were obturated with a combination of single cone, carrier based, and cold flowable gutta-percha obturation system. The tooth remained asymptomatic without reinfection and symptoms of failure for 18 months. CONCLUSION: Cone beam computed tomography is indispensable in treatment planning for cases where the radiographs cannot reveal useful information regarding the root canal shape. Postobturation CBCT has helped in avoiding further retreatment of the tooth, which otherwise is a challenging task. CLINICAL SIGNIFICANCE: The use of sophisticated equipment, such as dental operating microscope and CBCT has helped in accurate diagnosis and treatment planning of fused central incisor respectively.

BACKGROUND: A double tooth is a rare developmental anomaly referring to the fusion of two adjacent tooth buds or the gemination of a single bud. CASE REPORT: This case report describes the multidisciplinary approach to an 11-year-old patient with two double upper permanent incisors. The clinical intraoral examination showed a mixed dentition with bilateral double maxillary central incisors, molar Class I malocclusion and palatal ectopy of two lateral upper incisors. Computed tomography of the upper dental arch revealed the presence of double central incisors with two distinct roots. The clinical choice consisted of an innovative treatment including surgical, endodontic, orthodontic and restorative treatments. This management protocol produced good aesthetic, healthy and functional results that were stable also two years post-treatment.

Patients suffering from Ellis-Van-Creveld syndrome are a challenge for dental management. Aesthetics are a major concern with limited manual dexterity, making choice of treatment critical. A 38 year old female diagnosed with Ellis-Van-Creveld syndrome presented with stained teeth and un-aesthetic smile and related that to her low self-esteem and depression. Intra-oral examination revealed mal-aligned megadont central incisors in the maxillary arch, fused mandibular canines with laterals and missing central incisors with space discrepancy and pronounced reverse over jet and overbite. Treatment involved non-surgical periodontal management, fabrication of veneers and dentine bonded crowns for maxillary anteriors and fixed-fixed resin retained bridge for mandibular arch.

This case reports the concurrence of gemination and fusion affecting the maxillary central incisors of a twelve-year-old patient and the collaboration of the pediatric dentist, endodontist, orthodontist and oral and maxillofacial surgeon. Developmental dental anomalies can occur in both primary and permanent dentitions as a result of conjoining defects. Double teeth, or cases of gemination or fusion, are not exceedingly rare, but the presence of both anomalies in a single patient is a rarity. Gemination is the division of a single tooth bud, resulting in a large single tooth with a bifid crown and common root and root canal. Fusion is the union of two separate tooth buds, resulting in a joined tooth with confluence of dentin and separate root canals. Labial apexogenesis with MTA, composite resin placement, re-contouring and orthodontic care allowed proper alignment with long-term monitoring of growth and development for possible incisor replacement.

O objetivo deste estudo foi analisar por meio da microtomografia computadorizada os aspetos morfológicos e morfométricos da anatomia interna do sistema de canais radiculares com formato em C, e, avaliar a área de superfície, volume e áreas do canal não instrumentadas antes e após a instrumentação dos canais por meio de sistemas alternativos de instrumentação mecanizada, assim como, analisar o efeito de instrumentos manuais com movimento de 90º-oscilatório como instrumentação final. Cinquenta e dois segundos molares inferiores extraídos com canais em forma de C foram escaneados usando micro tomografia computadorizada. As secções transversais do canal radicular foram registradas de acordo com a classificação modificada de Melton. Os parâmetros morfométricos e a configuração tridimensional, foram avaliadas. Depois, 20 dentes com anatomias convergentes e configuração interna C1 foram divididos em dois grupos (n = 10) e instrumentados com Reciproc e SAF respectivamente. Em seguida, uma lima niti #30 do tipo K foi usado em movimento de 90º oscilatório como uma instrumentação final. Os espécimes foram escaneados usando Micro-CT após todos os procedimentos. Os parâmetros morfométricos foram analisados utilizando o programa CTAN. Além disso, a superfície do canal radicular não instrumentada foi calculada por terços. Os resultados indicaram uma distribuição uniforme dentro da amostra. Além disso, a análise da secção transversal revelou predominância das configurações de C4 e C3 a 1 mm a partir do ápice e as configurações C1 e C2 no terço cervical. De acordo com os parâmetros morfométricos, o tipo C1 e o canal distal do C2 apresentaram os menores valores de circularidade e valores mais elevados para a área, diâmetro maior e menor no terço apical. Todos os valores relativos a analise de instrumentação foram comparados entre os grupos utilizando o teste de Mann- Whitney e a comparação intra-grupos usando o teste de Wilcoxon. A instrumentação com Reciproc aumentou significativamente o volume do canal em comparação com SAF. Além disso, os volumes dos canais foram significativamente aumentados após a instrumentação de 90º-oscilatória (P <0,05). Depois de todos os protocolos de instrumentação, o aumento de área de superfície só revelou diferenças significativas na comparação intra-grupos (P <0,05). A instrumentação com Reciproc e SAF deixou 28% e 34%, de áreas não instrumentadas respectivamente, sem diferença estatística (P> 0,05). Já a instrumentação oscilatória final reduziu as superfícies do canal radicular não instrumentadas de 28% para 9% (Reciproc) e de 34% para 15% (SAF; P <0,05). Os molares inferiores com canais radiculares em forma de C apresentaram distribuições semelhantes de canais simétricos, assimétricos e convergentes. A configuração C1 e o aspecto distal da configuração C2 apresentaram os maiores valores de área de e diâmetros apicais. Além disso, o uso final da instrumentação com 90º oscilatório usando instrumentos manuais de NiTi diminuiu significativamente as paredes do canal não instrumentadas que permaneceram após a instrumentação com Reciproc e SAF. Finalmente, a combinação de dois sistemas ou técnicas de instrumentação provaram ser eficazes na obtenção de melhores resultados na instrumentação de segundos molares inferiores em forma de C.(AU)
The present study evaluated the morphometric aspects of the internal anatomy of the root canal and the effect of 90º-oscillatory instrumentation with hand files on volume, surface area and uninstrumented surface after shaping procedures with Self adjusting file and Reciproc in mandibular second molars with C-shaped canals. 52 extracted mandibular second molars with C-shaped canals were scanned with a micro-computed tomography scanner. The root canal cross-sections were recorded according to the modified Melton classification. Morphometric parameters and the tridimensional configuration, were evaluated. Afterwards, 20 teeth with merging type canals and C1 internal configuration were divided in two groups (n = 10) and instrumented with Reciproc and SAF instruments respectively. Then, a size 30 Niti hand K-file used in 90º-oscillatory was used as a final instrumentation. The specimens were scanned using Micro-CT after all procedures. Morphometric parameters were analyzed using CTAn software. Also, the uninstrumented root canal surface was calculated for each canal third. The results indicated an even distribution within the sample. Also, the cross-sectional configuration analysis revealed predominance of the C4 and C3 configurations at 1 mm from the apex and the C1 and C2 configurations in the cervical third. According to the morphometric parameters, the C1 and the distal aspect of the C2 exhibited the lowest roundness values and higher values for the area, major diameter and aspect ratio in the apical third. All values were compared between groups using the MannWhitney test and within groups using the Wilcoxon's signed-rank test. The significance level was set at 5%. Instrumentation with Reciproc significantly increased canal volume compared to SAF and the canal volumes were significantly increased after 90º-oscillatory instrumentation (P < 0.05). After all instrumentation protocols the surface area increase only revealed significant differences in the within groups comparison (P < 0.05). Reciproc and SAF instrumentation yielded a uninstrumented root canal surface of 28% and 34%, respectively, without differences (P > 0.05). Final oscillatory instrumentation reduced the uninstrumented root canal surface from 28% to 9% (Reciproc) and from 34% to 15% (SAF; P < 0.05). The apical and middle thirds exhibited higher uninstrumented root canal surfaces after the first instrumentation that was significantly reduced after oscillatory instrumentation (P < 0.05). Mandibular molars with C-shaped root canals exhibited similar distributions of symmetrical, asymmetrical and merging-type canals. The C1 configuration and the distal aspect of the C2 configuration exhibited the highest area values and large apical diameters. Furthermore, the final use of 90º-oscillatory instrumentation using NiTi hand files significantly decreased the uninstrumented canal walls that remained after Reciproc and SAF instrumentation. Finally, the combination of two instrumentation systems/techniques proved to be effective in achieving better instrumentation results in C-shaped mandibular second molars.(AU)

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. Although the images revealed a supernumerary tooth-like structure between the posterior area of the mandibular second molar and mandibular third molar, it was difficult to confirm the morphology of the tooth root apical area. Subsequent cone-beam computed tomography (CBCT) revealed that the supernumerary tooth-like structure was concrescent with the root apical area of the mandibular second molar. Based on these findings, the diagnosis was a fused mandibular second molar and paramolar with a concrescent supernumerary tooth. A 3-dimensional (3-D) printer was used to produce models based on the CBCT data to aid in treatment planning and explanation of the proposed procedures to the patient. These models allowed the complicated morphology involved to be clearly viewed, which facilitated a more precise diagnosis and better treatment planning than would otherwise have been possible. These technologies were useful in obtaining informed consent from the patient, promoting 3-D morphological understanding, and facilitating simulation of endodontic treatment.

PURPOSE: Developmental disturbances during tooth formation may cause abnormalities in tooth size and shape, resulting in poor dental and facial esthetics. The purpose of this study was to evaluate the prevalence of fused/geminated teeth in the maxillary anterior region of orthodontically treated patients, and present treatment options and their outcome. METHODS: Pre- and post-treatment facial and intraoral photographs, study models, and panoramic and periapical radiographs of 574 consecutively treated patients (mean age: 13.3 years) from the orthodontic department were examined for the presence of fusion or gemination in the maxillary anterior region. RESULTS: There were eight patients (1.4 percent) with fused/geminated teeth in the maxillary anterior region. CONCLUSIONS: The prevalence found is relatively high compared to previous reports. Esthetic consideration is a determining factor for various treatment alternatives. A multidisciplinary approach is imperative for the successful treatment of these dental abnormalities.

Double tooth and talon cusp are tooth shape anomalies with rare co-occurrences in a single tooth. Double tooth is a developmental anomaly that leads to the eruption of fused teeth and may contribute to compromised esthetics, pain, caries, and tooth crowding. Talon cusp is a rare developmental extra cusp-like projection on the cingulum area that may cause functional and esthetic problems. Differential diagnosis of these anomalies may be complicated. A multidisciplinary approach for the esthetic and functional rehabilitation of double teeth is important. Various treatment methods have been described in the literature for the different types and morphological variations of double teeth. The purpose of this paper is to report the case of an unusual combination of double tooth and talon cusp on a permanent maxillary incisor and describe its esthetic and functional rehabilitation using a porcelain laminate veneer.

INTRODUCTION: Macrodontia of anterior teeth may occur as an isolated condition or as a result of fusion or gemination and may cause clinical problems such as tooth crowding and esthetic problems. Preliminary planning and careful management are often required by a dental team comprising an orthodontist, an endodontist, a prosthodontist, and an oral surgeon. A multidisciplinary treatment approach in a case with fused teeth is presented. METHODS: A 9-year-old girl presented with macrodontia of a left maxillary central incisor. The patient was referred to the orthodontic department because of a large central incisor as a result of fusion with an unspecific supernumerary tooth. The surgical procedure included sectioning off the mesial segment as far as possible, both apically and subgingivally, and extracting 1 of the fused supernumerary teeth. During the sectioning procedure, the pulp of the remaining tooth was exposed at the middle third of the root. Direct pulp capping was performed by an endodontist using mineral trioxide aggregate. Twelve weeks later, orthodontic treatment was commenced, and finally after a 26-month orthodontic treatment period, the central incisors' crown was restored using composite material. RESULTS: A 10-year clinical and radiographic follow-up revealed that the remaining resected central incisor kept its vitality, and the patient was pleased with the esthetic result. CONCLUSIONS: Proper interdisciplinary treatment planning of complicated cases such as anomalous teeth, which involve fusion to a supernumerary tooth, may lead to minimal invasive conservative procedures that maintain tooth vitality and result in a pleasing esthetic result.

INTRODUCTION: The C-shaped configuration is rare in the upper first molar.The purpose of this article is to present 2 cases diagnosed during endodontic therapy and perform a literature review of this anatomy in the upper first molar. METHODS: Endodontic therapy was performed by using a dental operating microscope and a cone-beam computed tomography analysis for better understanding of this anatomy. A literature search was conducted to identify and compare all the published cases of C-shaped upper first molar. RESULTS: Before the cases reported in this article, only 5 cases were available in the published literature. Three different types of C-shaped configurations in the upper first molar have been presented. CONCLUSIONS: The C-shaped maxillary first molar is a rare anatomic configuration. The use of the dental operating microscope may help in the endodontic therapy of these cases. Three types of C-shaped configurations have been reported; the fusion of the distobuccal root with the palatal root appears to be the most usual one.

The term double tooth is often used to describe fusion and gemination. The development of isolated large or joined teeth is not rare, but the literature is confusing when the appropriate terminology is presented. The objective of this paper is to present a case of a primary double tooth in a 5-year-old girl with a history of trauma. The tooth was endodontically treated and esthetic management was carried out using a silicone putty guide.
