Objetivo: apresentar o relato de duas pacientes com agenesias dentárias em que cinco dentes autotransplantados foram utilizados como modalidade de tratamento. Além disso, objetiva-se mostrar questões sobre a técnica cirúrgica, suas indicações e previsibilidade. Relato de caso: Neste estudo, foram relatados 5 casos de autotransplante dentário em duas pacientes jovens, em que a equipe realizou os procedimentos e o acompanhamento clínico e radiográfico por 5 e 7 anos. Devido à alta sensibilidade da técnica, foram seguidos princípios previamente estabelecidos na literatura envolvendo o autotransplante dentário. Durante o período de acompanhamento, os dentes se mantiveram em posição e em função e as pacientes não apresentavam queixas associadas. Considerações finais: a técnica do autotransplante dentário, quando bem indicada e executada, é capaz de promover resultados bastante satisfatórios, sendo uma ótima alternativa reabilitadora, com taxas de sucesso elevadas e custos reduzidos. No entanto, critérios em relação aos sítios doadores e receptores e a habilidade do cirurgião devem ser levados em conta para o sucesso do técnica.

Objective: presenting the report of two patients with tooth agenesis in which five autotransplanted teeth were used as a treatment modality. Furthermore, the aim is to show questions about the surgical technique and its indications and predictability. Case report: In this study, 5 cases of dental autotransplantation were reported in two young patients, in which the team performed procedures and had clinical and radiographic follow-up for 5 and 7 years. Due to the high sensitivity of the technique, principles previously established in the literature involving dental autotransplantation were followed. During the follow-up period, the teeth remained in position and function and the patients had no associated complaints. Final considerations: the dental autotransplantation technique, when well indicated and executed, is capable of achieving very satisfactory results, being a great rehabilitative alternative, with high success rates and reduced costs. However, criteria regarding donor and receptor sites and the surgeon's skill must be taken into account for the success of the technique.

Considerations of the classification and treatment for fused teeth / 中华口腔医学杂志

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.

Prevalence of permanent numeric dental anomalies in panoramic radiography in an Iranian population

Aim: Dental number anomalies are a group of congenital developmental disorders divided into two groups supernumerary and missing teeth. This study was conducted to investigate the prevalence of numeric dental anomalies using panoramic images in patients referred to the Hamadan Dental Faculty. Methods: In this cross-sectional study, 2,197 panoramic radiographs of patients aged 6-49 years were evaluated. These anomalies are divided into two groups: 1) Supernumerary teeth, including Mesiodens, Distodens, and Peridens, and 2) Missing teeth, including Hypodontia, Oligodontia, and Anodontia. A Chi-square test was performed to assess the relationship between the anomalies. Data analysis was performed using SPSS 16, in which P-value < 0.05 was considered the statistical significance level. Results: Of 736 males (32.2%) and 1548 females (67.8%) in this study, 32 (4.3%) and 55 cases (3.8%) had supernumerary teeth, respectively. The prevalence of supernumerary teeth was 0.3%, 0.5%, and 0.6% in males and 0.2%, 1% and 1.2% in females for mesiodens, distodens, and peridens, respectively. Also, 243 males (10.6%) and 655 females (28.6%) had missing teeth anomalies. Hypodontia in the maxilla was the most common anomaly in both genders, while mesiodens was the least common. Conclusion: Hypodontia was the most common anomaly, followed by peridens; the least common anomaly was mesiodens. The prevalence of supernumerary teeth was greater in males, though the difference was not statistically significant. In comparison, females had a greater prevalence of missing teeth

Interdisciplinary treatment to replace missing upper lateral incisors, 4.5 years follow up / Tratamiento interdisciplinario para reposición de incisivos laterales superiores faltantes, seguimiento de 4,5 años

Introduction: Multidisciplinary diagnosis and planning are essential to define the treatment option that will provide the best individual results for patients with congenitally missing upper lateral incisors. Objective: To determine the function and aesthetics after the therapeutic use of osseintegrated implants to replace congenitally missing upper lateral incisors in a young female at 4.5 years follow-up. Case report: The patient was a 13 years old female (at beginning of treatment) with congenitally missing upper lateral incisors condition. Five months after the orthodontic active treatment, the space for placing the implants was achieved. After 2 years of Orthodontic treatment and the evaluation of the craniomandibular growth term by hand radiography, two implants were placed with an expanded bone technique in the position of the upper lateral incisors. After 4 months, osseointegration was clinically confirmed and two screw retained temporary crowns were performed using temporary plastic abutments and acrylic teeth and recalled at 4.5 years to control. Conclusions: Our results showed predictable esthetics and functional results in a patient with congenitally missing upper lateral incisors. This was possible due to a multidisciplinary approach between the diagnosis and treatment performed (Orthodontics, Implantology and Prosthodontics(AU)

Analysis of congenital deciduous teeth absence and its permanent teeth phenotype / 华西口腔医学杂志

OBJECTIVES@#This study aimed to investigate the clinical characteristics of congenital deciduous teeth absence and its permanent teeth performance type by using panoramic radiographs.@*METHODS@#A total of 15 749 panora-mic radiographs of 3-6-year-old children with deciduous dentition were collected from January 2020 to December 2021. The incidence of congenital deciduous teeth absence was observed, and the abnormality of permanent teeth was recor-ded. SPSS 24.0 software was used for statistical analysis.@*RESULTS@#The incidence of congenital deciduous teeth absence was 2.54% (400/15 749), which was found in 217 girls and 183 boys, and the difference between the genders was statistically significant (P=0.003). The absence of one and two deciduous teeth accounted for 99.75% (399/400) of the subjects. In addition, 92.63% (490/529) of mandibular deciduous lateral incisor was congenitally absent, 44.80% (237/529) of deciduous teeth was absent in the left jaw, and less than 55.20% (292/529) was absent in the right; the difference between them was statistically significant (P=0.017). The absence of 96.41% (510/529) deciduous teeth in the mandibular was significantly more than that of 3.59% (19/529) in the maxillary, and the difference between was statistically significant (P=0.000). Furthermore, 68.00% (272/400) and 32.00% (128/400) of deciduous teeth were absent in unilateral and bilateral, respectively, and the difference was statistically significant (P=0.000). Four types of congenital deciduous teeth absence with permanent teeth were observed as follows: 1) 73.91% (391/529) of permanent teeth was absent; 2) 20.60% (109/529) of permanent teeth was not absent; 3) the number of fused permanent teeth accounted for 4.91% (26/529); 4) the number of supernumerary teeth was 0.57% (3/529).@*CONCLUSIONS@#Although the absence of congenital deciduous teeth is less common than that of permanent teeth, it affects deciduous and permanent teeth to some extent. Dentists should pay attention to trace and observe whether abnormalities are present in the permanent teeth and take timely measures to maintain children's oral health.

Agenesias dentárias atípicas: relato de caso clínico / Atypical dental agenesis: clinical case report

A agenesia dentaria é uma anomalia de desenvolvimento caracterizada pela determinação congênita de menor numero de dentes, podendo estar associada a síndromes genéticas ou ocorrer isoladamente. Embora seja considerada uma das anomalias mais frequentes quando envolve terceiros molares, segundo pré-molares e incisivos laterais, sua ocorrência em dentes estáveis, tais como o canino e o primeiro molar permanente é rara. Desta forma, este relato apresentará o caso de uma paciente do sexo feminino, 8 anos idade, que iniciou tratamento de rotina na Clínica de Odontopediatria da UNIFENAS. Na anamnese não foi relatada pela responsável a ocorrência de alterações sistêmicas, nem queixa ou histórico odontológico relevante. No exame clínico odontológico, notou-se o não irrompimento do primeiro molar permanente superior direito (16). Diante dos exames de imagem, foi confirmada a agenesia do dente 16 e também do canino permanente superior direito (13). A agenesia, sobretudo de dentes estáveis e relevantes no arco dentário, pode comprometer o desenvolvimento adequado da oclusão, mastigação, fonação e estética. Desta maneira, é importante o diagnóstico precoce desta ocorrência com o objetivo de favorecer a elaboração de um adequado plano de tratamento e, minimizar as sequelas destas agenesias atípicas(AU)

Dental agenesis is a developmental anomaly characterized by the congenital determination of fewer teeth, may be associated with genetic syndromes or occur in an isolated form. Although it is considered one of the most frequent anomalies when it involves third molars, second lateral premolars and incisors, the occurrence in stable teeth, such as the permanent canine and the permanent first molar is rare. This report will present the case of an 8-year-old female patient who started routine treatment at the Pediatric Dentistry Clinic of UNIFENAS. In the anamnesis, the responsible person did not report the occurrence of systemic alterations, or a relevant dental complaint or history. On dental clinical examination, it was noticed the non-rupture of the permament maxillar right first molar (16). In view of the imaging tests, the agenesis of tooth 16 and also of the permanent maxillary right canine (13) was confirmed. Agenesis, especially of stable and relevant teeth in the dental arch, may compromise the proper development of occlusion, chewing, phonation and aesthetics. Thus, it is of paramount importance to early diagnosis of this occurrence in order to favor the development of an appropriate treatment plan in order to minimize the sequelae of these atypical agenesis(AU)

Prosthetic dental management of a patient with anhidrotic ectodermal dysplasia: a case report / Manejo protésico dental de un paciente con displasia ectodérmica anhidrótica: reporte de caso

Introduction: Ectodermal dysplasia (ED) comprises a broad group of genetic disorders characterized by alterations of the structures derived from the ectoderm, including those of the stomatognathic system. Case Report: The present article aims to report the prosthetic management of a patient with anhidrotic ectodermal dysplasia. A male patient diagnosed with ED who attended the dental consultation displaying oligodontia; underdeveloped alveolar ridges were observed. Results: The established treatment consisted of the adaptation of implant-supported fixed full-arch prosthesis designed through CAD-CAM technology for the lower jaw and of a removable partial prosthesis with muco-dental support for the upper jaw. The dental approach of patients with ED is based on a correct analysis of the facial characteristics and stomatological conditions of each subject. Conclusion: A multidisciplinary approach is mandatory due to the biological and functional complexity in biomechanical terms of these individuals.

Introducción: La displasia ectodérmica (DE) comprende un amplio grupo de trastornos genéticos caracterizados por alteraciones de las estructuras derivadas del ectodermo, incluidas las del sistema estomatognático. Reporte de Caso: El presente artículo tiene como objetivo informar del manejo protésico de un paciente con displasia ectodérmica anhidrótica. Paciente varón diagnosticado de DE acudió a consulta odontológica por oligodoncia; Se observaron crestas alveolares subdesarrolladas. Resultados: El tratamiento establecido consistió en la adaptación de una prótesis de arcada completa fija implantosoportada diseñada mediante tecnología CAD-CAM para el maxilar inferior y de una prótesis parcial removible con soporte muco-dental para el maxilar superior. El abordaje odontológico de los pacientes con DE se basa en un correcto análisis de las características faciales y condiciones estomatológicas de cada sujeto. Conclusión: Un enfoque multidisciplinario es obligatorio debido a la complejidad biológica y funcional en términos biomecánicos de estos individuos.

Pôde-se analisar também que não há causa exata, porém, existem fatores predisponentes, como os ambientais e os hereditários. Considerações finais: esta revisão de literatura poderá auxiliar os profissionais de saúde para a realização de diagnóstico e planejamento precoces, a fim de encontrar o melhor e mais eficiente tratamento para cada caso. O tratamento precoce, por uma equipe multidisciplinar, certamente garantirá uma melhor qualidade de vida aos pacientes.(AU)

Objective: to verify the main dental agenesis and associated factors in cleft lip and palate through a literature review. Methods: a literature review was carried out using PubMed, SciELO and Google Scholar databases. Literature review: 34 studies were included, 2 clinical studies, 1 retrospective study, 10 literature reviews, 4 case-control studies and 5 cross-sectional studies. In addition to 3 references chosen through other searches complementary to the review. From the included studies, it was verified a higher frequency of cleft lift and palate for the male sex, and a higher frequency of more severe clefts, such as the incisive transformation, in comparison to the labiopalatine. It can also be analyzed that there is no exact cause; however, there are environmental and hereditary predisposing factors. Final considerations: this literature review may help health professionals to carry out early diagnosis and treatment planning, in order to find the best and most efficient treatment for each case. Early treatment by a multidisciplinary team will certainly guarantee a better quality of life for patients.(AU)

Caracterización morfológica de caninos en premolares, un caso de anodoncia parcial de caninos maxilares / Morphological characterization of canine teeth done in first bicuspid, a maxillary canine partial anodontia case report

En este informe de caso clínico se muestra el tratamiento exitoso de un paciente con anodoncia parcial de órganos dentales 13 y 23 debido a que fueron extraídos por presentar impactación y mal pronóstico de tracción. En este artículo se presenta un paciente masculino de 29 años clase I esquelética con un perfil convexo, maloclusión de clase III, overjet disminuido, ausencia de guías funcionales, discrepancia oseodentaria positiva en arcada superior y negativa en arcada inferior. El tratamiento se realizó con extracciones de los órganos dentales 34 y 44 para nivelar las discrepancias óseo dentarias interarcadas, se llevó a cabo mediante un cierre de espacios recíproco por medio de cadenas elásticas para ambas arcadas, con lo que se logró crear un overjet y overbite adecuados. La creación de las guías caninas funcionales se consiguió mediante el cambio de morfología de los órganos dentales 14 y 24, los cuales fueron llevados a la posición de los caninos ausentes. El tiempo total de tratamiento para este paciente fue de 24 meses. Se realizaron ameloplastias positivas, la aplicación de agregados de resina para mejorar la funcionalidad y proveer salud articular. Se sugiere que ante casos de anodoncia de caninos en la arcada superior, un tratamiento favorable se puede llevar a cabo mediante el cierre de espacios, la caracterización morfológica de los caninos ausentes mediante ameloplastias positivas en premolares (AU)

This case report shows the successful treatment of a patient with partial anodontia of dental organs 13 and 23 because they have been extracted due to present impactation and poor traction prognosis. This article presents a 29-year-old male class I skeletal patient with convex profile, class III malocclusion, overjet reduction, absence of functional guidance, positive bone-teeth discrepancy in the upper arch and negative in the lower arch. The treatment was carried out with the extractions of the dental organs 34 and 44 for correcting oral dental discrepancies between upper and lower arches; it was done using reciprocal closing of spaces by using elastic chains for both arches in order to achieve a suitable overjet and overbite. The creation of the canine guides was achieved by changing the morphology of the dental organs 14 and 24, which were taken to the position of the absent canines. The total treatment timing for this patient was 24 months. Positive ameloplasties were performed by application of resin aggregates to improve functionality and provide joint health. A favorable treatment for these kinds of cases of canine anodontics in the upper arch is carried out by closing spaces and the morphological characterization of the absent canines by positive in-premolar ameloplasties (AU)

Carillas directas, una opción en dientes deciduos por agenesia del diente permanente. Reporte de caso / Direct veneers, option in temporary teeth duo to agenesis of the permanent tooth. A case report

La ausencia congénita de al menos un diente es una anomalía dental la cual puede darse durante las etapas iniciales de la formación dentaria. La agenesia dental puede ser clasificada como hipodoncia cuando se describe la agenesia de uno a seis dientes, sin con- siderar terceros molares, la prevalencia de esta anomalía varía en función de la demografía y el perfil geográfico, oscilando entre un 0,03 a 10% y afectando más a mujeres que a hombres, según lo que se indica en los estudios puede ser motivo de una alteración genética la cual produce la ausencia de dientes permanentes. El tratamiento de la agenesia dentaria requiere un enfoque multidisciplinario odontológicamente y a partir de los estudios exhaustivos del caso, determinar un plan de tratamiento completo. En la actualidad, se ha observado un gran desen- volvimiento en las resinas compuestas, ofreciendo una oportunidad de reproducir con gran fide- lidad los dientes naturales. El tratamiento de carillas directas es una técnica muy conservadora donde se aplica la resina compuesta sin realizar red ucción en el diente. El presente es un reporte de caso clínico que tiene objetivo presentar el abordaje clinico mediante la elaboración de carillas directas con resina compuesta en un paciente con agenesia dental de los incisivos centrales inferiores permanentes, donde el paciente aún conserva sus incisivos centrales inferiores primarios sin reabsorción radicular. El tratamiento se indica para lograr tener una mejor estética y función...(AU)

Maxillary Occlusion rehabilitation of multiple anterior teeth agenesis followed by tooth wear: A case report

@#A 19-year-old female patient came with the chief complaint that the upper anterior teeth looked small and with many spaces. The patient claimed that the tooth had never been replaced since birth. The patient wanted to improve the aesthetics of the tooth. Treatment, in this case, was made using a fixed prosthetic to aesthetically rehabilitate through prosthodontic treatment in the anterior teeth agenesis followed by attrition. It can be concluded that fixed prosthodontic treatment using a splint bridge is one treatment option that can be used in multiple anterior teeth agenesis followed by tooth wear. An appropriate material selection increases the aesthetics and functional aspects of the final treatment.

Prosthodontic Rehabilitation of Bilateral Maxillary Lateral Incisors Agenesis: A Case Report with One-Year Follow-Up

ABSTRACT@#Globally, non-syndromic tooth agenesis is commonly seen in clinical practice. However, its management is often complex and requires a multidisciplinary team approach for the maximal outcome. While various treatment options are possible, considerations for the treatment are not only based on the dentofacial conditions but also cultural and social background and personal preference of the patient. Thus, patientcentred care approach should always be practised for an optimal outcome. In the present case, a patient with established craniofacial growth presenting with bilateral agenesis of maxillary lateral incisors and over-retained deciduous maxillary left canine sought for aesthetic improvements. The patient did not prefer any orthodontic treatment citing a prolonged treatment duration and sub-optimal motivation as a hindrance. Thus, a prosthodontic only approach was taken by providing a conventional cantilever bridge and ceramic veneers to achieve the aims of treatment. This article discusses the possible limitation of such prosthodontic only solution in managing tooth agenesis.

Radiographic Assessment of Third Molars Agenesis Patterns in Young Adults

ABSTRACT Objective: To determine the prevalence of third molar agenesis and associated characteristics. Material and Methods: A total of 2374 panoramic radiographs were retrieved from the radiological archives and evaluated in a computer monitor under optimum viewing conditions. The basic demographic data (age and sex) and the primary findings regarding the presence or absence of third molars in the maxillary and mandibular arches were recorded systematically in a specially designed proforma. Categorical variables were compared using the Chi-square test. Results: A total of 2000 panoramic radiographs were included in the study, of which 1004 were females (50.2%), and 996 were of males (49.8%). The incidence of third molar agenesis was 486 patients (24.3%). Maxillary third molar showed a higher prevalence of agenesis (28.8%) than mandibular third molars (16.4%). A total of 1514 patients (75.7%) had third molars in all four quadrants, and the remaining 486 patients (24.3%) had agenesis of third molar tooth in at least one of the quadrants. Single tooth agenesis was observed in 219 (11%) patients, two teeth agenesis in 172 (8.6%) patients, three teeth agenesis in 39 (2%) patients, and four teeth agenesis in 56 (2.8%) patients. Conclusion: The present study exhibited a maximum number of single tooth agenesis. It was also observed that maxillary third molar agenesis is more than the mandibular third molar and the right side is more than the left side. Agenesis of the third molar is more prevalent in males as compared to females.
