ABSTRACT

Background: Radiographs are used by orthodontists in the diagnosis of malocclusion, treatment planning and monitoring. These usually reveal presence of dental anomalies that may require further assessment and management. Objective: To investigate the prevalence, types and distribution of dental anomalies seen on the orthopantomograms (OPGs) of orthodontic patients at the University of Port-Harcourt Teaching Hospital (UPTH).Methods: This was a retrospective cross-sectional radiographic study of a cohort of orthodontic patients who presented to the Department of Child Dental Health, University of Port Harcourt Teaching Hospital, Rivers State, Nigeria. The data gathered from digital orthopantomograms of the patients was analysed using IBM Statistical Package for Social Sciences (SPSS) Statistics for Windows version 25.0. Results: The study comprised 249 patients with an age range of 5-44years (mean age of 14.6±7.7years) comprising 108 (43.4%) males and 141 (56.6%) females.Seventy (28.1%) [(29, 41.4% males), (41, 58.6% females)] of the patients had at least one dental anomaly. Dental anomalies were commonest (48, 68.6%) within 10-19 years age bracket followed by the 0-9 years age bracket (11, 15.7%). The most frequent dental anomaly was taurodontism (43, 61.4%), followed by congenitally missing teeth (8, 11.4%), supernumerary teeth (5, 7.1%), odontoma (4, 5.7%), peg shaped lateral incisors and transposition (2, 2.9%) respectively. Dental anomalies were more frequent in the maxilla (43, 61.4%). Conclusion: The most common dental anomaly was taurodontism. Anomalies were more frequent in female than male patients and in the maxilla than in the mandible

ABSTRACT

Panoramic radiographs are complementary exams to evaluate oral alterations in an early manner, these changes can be dental developmental anomalies, and post-eruption dental disorder. Aim: This study evaluated the findings in panoramic radiographs and correlated the variables of gender and dental location. Methods: A retrospective study was through the observation of 1.111 panoramic radiographs from the Radiology Department in Brazil. It was included patients from 5 to 79 years of age of both gender, and it classified the anomalies in shape, size, and number and post-eruption dental changes in and correlated with gender and location. Patients with syndromes were excluded from the sample. Results: The majority of the sample was composed of fameles 752 (67.7%), as to the frequency of dental developmental anomalies related lesions 684 cases (61.6%) and post-eruption dental disorder 567 (51.8%), in the radiographs. The most prevalent change was endodontic treatment (32.6%), followed by root dilaceration (25.9%), and included tooth (19.5%). The most prevailing alteration when correlated with the gender variables was the cyst root (p<0.01) in females, and orthodontic treatment (p=0.02) in males and the variable location in the mandible was root dilaceration, giroversion, impacted tooth, taurodontia, microdontia, and endodontic treatment (p<0.01). Conclusion: Our findings provide evidence that dental developmental anomalies e post-eruption dental disorder are frequent alterations in the population with particular characteristics of distribution by sex and location

ABSTRACT

Aim: Dental imaging has been widely used for diagnosis in dentistry. However, dental X-ray may induce cytotoxicity leading to apoptosis in oral mucosa cells. The present study aimed to observe the maturation pattern of buccal and gingival cells after exposure to X-ray radiation from analog/digital panoramic scanning and cone beam computed tomography (CBCT). Methods: The research samples were 40 subjects who fulfilled the inclusion and exclusion criteria. The subjects were divided into the exposed (patients who received analog/digital panoramic radiography or CBCT) and controlled (patients who had no radiography examinations) groups, with 10 subjects in each group. Exfoliative cytology smears were obtained from buccal mucosa and gingiva before exposure (or on day 0 for the control group) and 10 days later. The cells were stained with the Papanicolaou method. Then, the superficial, intermediate, and parabasal cells were counted in each glass slide. Results: No significant differences (p > 0.05) were observed among all cell types between day 0 and 10 in the control group. Meanwhile, after exposure to three kinds of radiography examinations, the frequency of intermediate cells in buccal mucosa and gingiva increased (p < 0.05), but that of superficial cells decreased (p < 0.05) significantly. No significant difference was found in the parabasal cells (p > 0.05). The frequency differences between intermediate and superficial cells showed no significant difference between the buccal mucosa and gingiva. Conclusion: Analog/digital panoramic radiography and CBCT exposure can induce cytotoxicity by altering the maturation pattern of buccal mucosa cells and gingiva, so it is strongly recommended to only perform these procedures if necessary and avoid repeated exposure to the same patient

ABSTRACT

El queratoquiste es una lesión odontogénica benigna de comportamiento agresivo, que deriva probablemente de la lámina dental. Se localiza frecuentemente en la parte posterior del hueso mandibular en la zona del tercer molar, ángulo mandibular y puede progresar hacia la rama y el cuerpo, presentando una asociación directa con órganos dentales retenidos. Existe una amplia variedad de técnicas para el tratamiento de esta lesión, como pueden ser descompresión, marsupialización, enucleación y la resección en bloque, así como también la combinación de estas con métodos coadyuvantes. El interés en esta lesión radica por su elevado índice de recidiva que se estima en un 20-30% en la población en general, sin embargo, en la actualidad se ha optado por el uso de tratamientos conservadores como la marsupialización y la descompresión que han demostrado una mayor efectividad y menor recidiva. Es por esto que tras el tratamiento de las lesiones es importante dar un seguimiento a largo plazo. El objetivo de la publicación es presentar el reporte de un caso clínico de un paciente masculino de 21 años con un diagnóstico de queratoquiste odontogénico tratado con una técnica de descompresión durante cinco meses para su posterior enucleación quirúrgica.Se ha comprobado que el tratamiento de descompresión seguido de enucleación y acompañado de métodos coadyuvantes resulta un manejo terapéutico adecuado para los queratoquistes por demostrar su menor tasa de recidiva y su comportamiento noble con estructuras vitales vecinas. Sin embargo, en todos los casos se debe realizar un seguimiento periódico para prevenir la recurrencia de la lesión.


Introduction: Keratocyst is a benign odontogenic lesion with aggressive behavior, probably derived from the dental lamina. It is frequently located in the posterior part of the mandibular bone in the area of the third molar, mandibular angle and can progress towards the ramus and the body, presenting a direct association with retained dental organs. There is a wide variety of techniques for the treatment of this lesion, such as decompression, marsupialization, enucleation, and en bloc resection, as well as the combination of these with adjuvant methods. The interest in this lesion stems from its high recurrence rate, which is estimated to be 20-30% in the general population, however, at present the use of conservative treatments such as marsupialization and decompression has been chosen. demonstrated greater effectiveness and less recurrence. This is why after treating the lesions it is important to give a long-term follow-up.The objective of the publication is to present the report of a clinical case of a 21-year-old male patient with a diagnosis of odontogenic keratocyst treated with a decompression technique for five months for subsequent surgical enucleation.Conclusion: It has been proven that decompression treatment followed by enucleation and accompanied by adjuvant methods is an adequate therapeutic management for keratocysts as it demonstrates its lower rate of recurrence and its noble behavior with neighboring vital structures. However, in all cases, regular monitoring should be carried out to prevent recurrence of the lesion

ABSTRACT

Resumo O objetivo foi analisar a série temporal de procedimentos de imagem em Odontologia realizados entre os anos de 2000 e 2016 no Sistema Único de Saúde (SUS). Os dados foram obtidos do Sistema de Informações Ambulatoriais (SIA-SUS). Foram analisadas a influência da Política Nacional de Saúde Bucal de 2004, da Portaria nº 600/2006 (institui o financiamento dos Centros de Especialidades Odontológicas - CEOs) e Portaria nº 1.234/2013 (Incentivo financeiro do Programa de Melhoria do Acesso e da Qualidade - PMAQ-CEO). Apresentou-se análises descritivas dos anos inicial e final da série temporal, avaliando tendências e sazonalidade em sete tipos de procedimentos. A série temporal das taxas de exames radiográficos periapicais/interproximais demonstrou tendência de aumento moderado e foi a única em que se observou o impacto da política de implementação financeira dos CEOs, mas não do PMAQ-CEO. Os exames extraorais como: radiografia panorâmica, Tomografia Computadorizada (TC) da face/Articulação Temporomandibular (ATM) e Ressonância Magnética (RM) da ATM possuem forte tendência de aumento apesar das taxas serem muito baixas. Conclui-se que entre os anos 2000 e 2016, a política de expansão da atenção secundária, aumentou o uso de exames de imagem periapical/interproximal.


Abstract The scope of this paper was to analyze the time series of dental procedures performed between 2000 and 2016 in the Brazilian Unified Health System (SUS). The data were obtained from the Outpatient Information System of the SUS (SIA-SUS). The influence of the 2004 National Oral Health Policy of Ordinance No. 600/2006 (which instituted the financing of Dental Specialty Centers - CEOs), and Ordinance No. 1,234/2013 (Financial incentive for the Program for Enhancement of Quality and Access - PMAQ-CEO) were analyzed. Descriptive analyses of the initial and final years of the time series were presented, assessing trends and seasonality in seven types of imaging procedures. The time series of rates of periapical/bitewing radiographic exams revealed a trend of moderate increase and was the only area in which the impact of the financial implementation policy of the CEOs was observed, though not of the PMAQ-CEO. Extraoral imaging exams, such as panoramic radiography, facial CT/TMJ and TMJ MRI revealed a strong upward trend, despite the very low rates. The conclusion reached is that between 2000 and 2016, the policy of expansion of secondary care increased the use of periapical/bitewing imaging exams.

ABSTRACT

Introducción: El ameloblastoma es un tumor odontogénico epitelial benigno con tendencia a la recurrencia local si no se elimina adecuadamente. Las alternativas reconstructivas incluyen el uso de colgajos libres microvascularizados, placas y prótesis personalizada de titanio. Objetivo: Describir un reemplazo hemimandibular con prótesis personalizada de titanio posterior a la exéresis de ameloblastoma. Presentación del caso: Mujer de 44 años de edad, que presentó un hallazgo radiográfico durante la realización de tratamiento pulporradicular del diente número 37. Al realizársele el reconocimiento físico facial mostró aumento de volumen en región geniana izquierda mientras que el examen intrabucal detectó expansión de las corticales en la arcada posteroinferior del mismo lado. Se realizó una radiografía panorámica y tomografía axial computarizada con la que se constató la presencia de imagen radiolúcida, multiloculada, en forma de "pompas de jabón" extendiéndose desde el cuerpo mandibular hasta el cóndilo del lado izquierdo. Se tomó muestra para biopsia, con la cual se constató que se trataba de ameloblastoma con patrón folicular. Se realizó abordaje cervical, segmentaria mandibular con margen de seguridad y exarticulación. Se reemplazó la porción eliminada con prótesis personalizada de titanio. Se mantuvo el chequeo posoperatorio en el que se comprobó una buena evolución. Conclusiones: La cirugía constituyó el pilar de tratamiento utilizado. Una vez realizada la resección quirúrgica se reconstruyó el defecto con prótesis personalizada de titanio, proceder de gran novedad en nuestro medio y útil para restablecer la función y estética(AU)


Introduction: Ameloblastoma is a benign tumor of odontogenic epithelium with a tendency to local recurrence if not removed appropriately. Reconstruction alternatives include the use of microvascularized free flaps, plates and customized titanium prostheses. Objective: Describe a case of mandibular replacement with a customized titanium prosthesis after ameloblastoma excision. Case presentation: A case is presented of a female 44-year-old patient who presented a radiographic finding during pulporadicular treatment of tooth 37. Facial physical examination found an increase in volume in the left genian region, and intraoral observation detected expansion of the corticals in the lower posterior arch of the same side. Panoramic radiography and computed axial tomography showed a multilocular radiolucid image resembling soap bubbles which extended from the mandibular body to the left condyle. A sample was taken for biopsy, which confirmed the diagnosis of follicular pattern ameloblastoma. Segmental mandibular surgery was performed by cervical approach with a safety margin and exarticulation. The portion removed was replaced with a customized titanium prosthesis. Post-operative control showed a good evolution. Conclusions: Surgery was the basic component of the treatment applied. Surgical resection was followed by reconstruction of the defect with a customized titanium prosthesis, a procedure of great novelty in our environment useful to restore function and esthetic appearance(AU)

ABSTRACT

Introducción: La etiología de la sinusitis maxilar comprende diferentes causas primarias y secundarias. Siempre es preciso descartar de inicio aquellas causas iatrogénicas consecuencia de intervenciones previas. Objetivo: Realizar una revisión de las diferentes causas de sinusitis maxilar, con énfasis en las causas raras iatrogénicas y en el protocolo de actuación. Presentación del caso: Paciente varón de 60 años que presenta episodios de sinusitis maxilar. Como antecedentes quirúrgicos se había realizado quistectomía maxilar, tratamiento de fístula oroantral secundaria y rehabilitación protésica posterior. Tras estudio radiológico inicial se halló una masa intrasinusal, compatible al tacto con material de impresión dental. Conclusiones: Es importante antes de cualquier rehabilitación protésica y de la toma de modelos confirmar la ausencia de fístula oroantral para evitar la intrusión de material extraño en el seno maxilar(AU)


Introduction: The etiology of maxillary sinusitis comprises a number of primary and secondary causes. It is always necessary to initially rule out iatrogenic causes resulting from previous interventions. Objective: Carry out a review of the different causes of maxillary sinusitis, with an emphasis on the rare iatrogenic causes and the clinical management protocols. Case presentation: A male 60-year-old patient who experiences episodes of maxillary sinusitis. Surgical antecedents include maxillary cystectomy, treatment for secondary oroantral fistula and posterior prosthetic rehabilitation. Initial radiological examination revealed an intrasinus mass compatible to the touch with dental impression material. Conclusions: Before any sort of prosthetic rehabilitation and the taking of models, it is important to confirm the absence of an oroantral fistula, to prevent the entrance of foreign material into the maxillary sinus(AU)

ABSTRACT

Objetivo: Comparar el ángulo de la guía condílea sagital obtenida del registro radiográfico y clínico en pacientes dentados. Materiales y métodos: La muestra estuvo conformada por un grupo único de estudio de 32 pacientes, en el que se evaluó la radiografía lateral estricta y los registros posicionales: en relación céntrica, registro protrusivo a 5 mm en lateralidad derecha y registro protrusivo a 5 mm en lateralidad izquierda. Con el registro posicional del arco facial se articuló el modelo superior, con el registro posicional en relación céntrica se articuló el modelo inferior, con los registros laterales protrusivos de los lados derecho e izquierdo se obtuvo la medida del ángulo de la guía condílea sagital para la programación del articulador semiajustable. El plan estadístico en la presente investigación utilizó el programa SPSS versión 24, la normalidad fue evaluada usando el test de Shapiro-Wilk, también se realizaron las pruebas de T de Student y correlación de Pearson. Resultados: Se determinó estadísticamente que el género y la edad influyen en la medida del ángulo de la guía condílea sagital. El método radiográfico presentó un ángulo de guía condílea de 35,69 ±5,18 y con el método clínico fue 35,69 ± 5,16 (p > 0,05). La prueba de correlación de Pearson sí mostró una correlación importante entre ambos métodos r = 0,948, p < 0,001. Conclusiones: Existe alta correlación en las medidas obtenidas del ángulo de la guía condílea sagital con los registros radiográficos y clínicos; esta concordancia permitiría reemplazar un método por el otro. (AU)


Objective: To compare the angle of the sagittal condylar guidance obtained from the radiographic and clinical records of dentate patients. Materials and Methods: The sample consisted of 32 patients in whom strict lateral radiography and positional records were performed: in centric relation, protrusive recording 5 mm in right laterality and protrusive recording 5 mm in left laterality. With the positional registration of the facebow, the upper model was articulated, while the lower model was articulated with the positional registration in centric relation, and with the protrusive lateral registrations on the right and left side the condylar guidance was obtained for programming the semi-adjustable articulator. Statistics were performed with the SPSS program version 24 in Spanish. Normality was evaluated using the Shapiro-Wilk test, for data with normal distribution, and the Student's T test and Pearson's correlation were performed in descriptive statistics. Results: The statistical analyses showed that gender and age influence the angle measurement of the sagittal condylar guide. The radiographic method presented a condylar guide angle of 35.69 ± 5.18, being 35.69 ± 5.16 with the clinical method (p> 0.05). Pearson's correlation test showed an important correlation between the two methods (r = 0.948, p <0.001). Conclusions: There is a high correlation in the measurements obtained from the angle of the sagittal condylar guide and the radiographic and clinical records, indicating that both methods are effective.

ABSTRACT

Cleidocranial dysplasia (CCD), also known as Marie-Sainton syndrome, is a rare disorder of autosomal dominant type that presents specific characteristics at the skeletal and dental level. The diagnosis of CCD is based on clinical and radiographic findings. Panoramic, cephalometric and anterior poster radiographs have been used for its diagnosis in dentistry. However, these radiological techniques have limitations, and advances in technology with new imaging studies such as magnetic resonance imaging (MRI) and ultrasound have emerged, contributing to the diagnosis of CCD. Therefore, the aim of this review was to identify and describe current imaging studies that contribute to both the diagnosis and adequate and efficient treatment planning of CCD, and describe the clinical and radiographic characteristics of patients with this syndrome. (AU)


La displasia cleidocraneal (DCC), también conocida como síndrome de Marie-Sainton, es un trastorno poco común de tipo autosómico dominante, que presenta características específicas a nivel esquelético y dental. El diagnóstico de DCC se basa en hallazgos clínicos y radiográficos. Las radiografías panorámicas, cefalométricas y posteroanteriores se han utilizado para su diagnóstico en el área de la odontología, pero con los avances de la tecnología y debido a las limitaciones de estas técnicas radiológicas han surgido nuevos estudios de imagen como la resonancia magnética (RM) y la ecografía, que contribuyen al diagnóstico de DCC. Por lo tanto, el propósito de esta revisión fue identificar y describir los estudios de imagen actuales que aportan tanto al diagnóstico como a la planificación del tratamiento adecuado y eficiente de la DCC, y permiten describir las características clínicas y radiográficas de los pacientes con este síndrome.

ABSTRACT

As anomalias de desenvolvimento dos dentes, como a displasia dentinária, podem ser observadas durante os exames clínicos e radiográficos em alguns pacientes. O presente relato de caso discute sobre a Displasia Ectópica Dentinária (DD), sendo um distúrbio de desenvolvimento relacionado a formação da dentina que possui obliteração da polpa e defeito da formação da raiz. Descrita como uma condição rara e transmitida geneticamente. Ela pode ser dividida em tipos I e II, uma vez que ambas podem afetar as dentaduras decídua e permanente. O tratamento clínico transformou-se com o passar dos anos, sendo que o protocolo indicava a necessidade de exodontia para um tratamento menos invasivo, utilizando métodos que consistem na manutenção da higiene oral, a idade do paciente, a gravidade da doença, a extensão dos sintomas e atendimento odontológico regular. Este trabalho tem como objetivo apresentar o caso clinico de um menino de 8 anos, diagnosticado com displasia dentinária do tipo I e com presença de restaurações insatisfatórias na dentição mista. Dessa forma é significativo o planejamento adequado, em favor de melhorias na manutenção profilática... (AU)


Anomalies in the development of teeth, such as dentin dysplasia, can be observed during clinical and radiographic examinations in some patients. The present case report discusses Dentinal Dysplasia Ec topic (DD), being a developmental disorder related to the formation of dentin that has pulp oblitera tion and root formation defect. Described as a rare and genetically transmitted condition. It can be divided into types I and II, since both can affect deciduous and permanent dentures. Clinical treatment has changed over the years, and the protocol indicated the need for extraction for a less invasive treat ment, using methods that consist of maintaining oral hygiene, the age of the patient, the severity of the disease, the extent of symptoms and regular dental care. This paper aims to present the clinical case of an 8-year-old boy, diagnosed with type I dentin dysplasia and with the presence of unsatisfactory restorations in the mixed dentition. Thus, adequate planning is significant, in favor of improvements in prophylactic maintenance... (AU)

ABSTRACT

Objective: The aim of this study was to update the concepts of the diagnosis of idiopathic osteosclerosis (IO) of the jaws by digital panoramic radiographs and cone beam tomography and describe the impact of this disease on oral and general health. Methods: A search of the main databases of dental medical research was carried out using the search terms "osteosclerosis, panoramic radiography, cone beam computed tomography, jaws". Articles without language restriction until September 30, 2020 were identified. The prevalence and clinical and radiographic characteristics of IO of the jaws were examined in 2D and 3D imaging studies, as well as the interaction during treatments in the various dental specialties. Results: We analyzed the current situation regarding the diagnosis of IO, with an update of the diagnostic criteria used to accurately identify IO in the latest generation imaging studies, as well determine its possible interactions in oral an general health. Conclusions: It is important to have a clear differential diagnosis of IO and be able to distinguish different radiopacities in the maxilla. Accurate reporting and monitoring of the morphometric characteristics are necessary taking into account the impact the presence of IO of the jaws has on future dental treatments. (AU)

ABSTRACT

Objective: The objective of this study was to evaluate mandibular osteoporotic alterations in patients with HIV infection in comparison to non-HIV-infected patients using panoramic radiographs. Material and Methods: 26 HIV-infected patients and 142 non-HIV-infected patients (control group) were included in this study. Panoramic radiographs of the participants were assessed considering mandibular cortical index (MCI). Non-parametric comparisons between groups were performed, using Mann-Whitney test, at a level significance level of p= 0.05. Results: HIV-infected patients presented lower bone mineral density (BMD) at mandible, assessed by MCI in panoramic radiographs when compared to non-HIV-infected patients. The medication intake of HIV-infected patients was highly heterogeneous and could not be associated to the low BMD presented in the mandibular cortex. Conclusions: HIV-infected patients may present lower mandibular BMD than non-HIV-infected patients. (AU)


Objetivo: O objetivo deste estudo foi avaliar as alterações osteoporóticas mandibulares em pacientes com infecção por HIV comparando-os com pacientes não infectados, por meio de radiografias panorâmicas. Material e Métodos: 26 pacientes infectados pelo HIV e 142 pacientes não infectados (grupo controle) foram incluídos neste estudo. As radiografias panorâmicas dos participantes foram avaliadas considerando o índice da cortical mandibular (MCI). Comparações não paramétricas entre os grupos foram realizadas, com o teste de Mann-Whitney e nível de significância de p = 0,05. Resultados: Pacientes infectados pelo HIV apresentaram menor densidade mineral óssea (BMD) na mandíbula, avaliada pelo MCI em radiografias panorâmicas, quando comparados aos pacientes não infectados pelo HIV. A ingestão de medicamentos de pacientes infectados pelo HIV foi altamente heterogênea e não pôde ser associada à baixa BMD apresentada no córtex mandibular. Conclusões: Pacientes infectados pelo HIV podem apresentar BMD mandibular menor do que pacientes não infectados pelo HIV. (AU)

ABSTRACT

Objective: One of the techniques of estimating age in forensic medicine, which is associated with the least trauma in both living individuals and corpses, is to use teeth. Accordingly, the present study aims to determine the relationship between chronological age and pulp-to-tooth area ratio and pulp-to-root width ratio in maxillary and mandibular canines on panoramic radiographs among the Iranian population. Material and Methods: A total of 162 panoramic radiographs were evaluated in the present study. Selected patients were of verified age with the age range of 15-45 years. The pulp-to-tooth area ratio (PTR) and the pulp-to-root width ratio were calculated with AutoCAD 2016 software program in maxillary and mandibular canines at two points of the root. The two points include cemento-enamel Junction (CEJ) and pulp/root width at the quarter of a distance between CEJ and end point of root-canal, which was named WA, WB respectively. The patients' age was also estimated with the use of linear regression equation. Then each patient's chronological age and the age estimated using this technique was compared. Results: The relationship between PTR in both canines and WB variable in maxilla with chronological age was inverse and significant (P < 0.05); However, there was no strong correlation coefficient (r≤- o.37). Gender had no effect on the results of the study. The mean difference between predicted age and actual age with combined PTR and WB formula was lower than 1 year. When the mean of PTR or WB variables was considered as a predictor, significant results were obtained (P < 0.05), showing a decrease in Standard error of estimation (SEE). The results were not significant when variables of upper PTR and lower PTR and the interaction between them were included in the linear regression model (p > 0.05). Same results were obtained with the variable of WB. Conclusion: Combining the variables of PTR and WB gives better results than using variables alone. Estimation of age with the mean of each variable shows less error than their combination. (AU)


Objetivo: Uma das técnicas de estimativa da idade na medicina legal, que está associada ao menor trauma em indivíduos vivos e cadáveres, é usar os dentes. Nesse sentido, o presente estudo tem como objetivo determinar a relação entre a idade cronológica e a relação área polpa-dente e relação largura-polpa-raiz em caninos superiores e inferiores em radiografias panorâmicas na população iraniana. Material e Métodos: Um total de 162 radiografias panorâmicas são avaliadas no presente estudo. Os pacientes selecionados são da idade verificada com a faixa etária de 15-45 anos. A relação de área polpa-dente (PTR) e a relação largura-polpa-raiz são calculadas com o programa de software AutoCAD 2016 em caninos superiores e inferiores em dois pontos da raiz. Os dois pontos incluem a junção cemento-esmalte (CEJ) e a largura da polpa / raiz no quarto de distância entre a CEJ e o ponto final do canal radicular, que é denominado WA, WB. A idade dos pacientes também é estimada com o uso da equação de regressão linear. Em seguida, a idade cronológica de cada paciente e a idade estimada usando esta técnica são comparadas. Resultados: A relação entre a PTR em ambos os caninos e a variável WB na maxila com a idade cronológica é inversa e significativa (P <0,05); No entanto, não existe um coeficiente de correlação forte (r≤- o.37). O gênero não tem efeito nos resultados do estudo. A diferença média entre a idade prevista e a idade real com a combinação de PTR e fórmula WB é inferior a 1 ano. Quando a média das variáveis PTR ou WB é considerada como preditora, resultados significativos são obtidos (P <0,05), mostrando uma diminuição no SEE. Os resultados não são significativos quando as variáveis de PTR superior e PTR inferior e a interação entre elas são incluídas no modelo de regressão linear p> 0,05). Os mesmos resultados são obtidos com a variável de WB. Conclusão: Combinar as variáveis de PTR e WB dá melhores resultados do que usar variáveis sozinhas. A estimativa da idade com a média de cada variável apresenta menos erros do que sua combinação. (AU)

ABSTRACT

Abstract Mucopolysaccharidosis (MPS) is a group of rare and inherited metabolic disorders caused by the accumulation of macromolecule glycosaminoglycans inside lysosomes. Affected individuals may have dental and craniofacial tissue alterations, facilitating the development of several oral diseases. Objectives To assess, with panoramic radiographic images, the frequency of dental and maxillomandibular incidental findings among MPS individuals and compare them with non-MPS individuals. Methodology A cross-sectional study evaluating a sample of 14 MPS individuals and 28 non-MPS individuals aged from 5 to 26 years was carried out. They were matched for sex and age on a 2:1 proportion. Panoramic radiographs were assessed for the presence/absence of the following dental and maxillomandibular alterations: dental anomalies of number (hypodontia/dental agenesis, supernumerary teeth); anomalies of form (microdontia, macrodontia, conoid teeth, taurodontism, and root dilaceration); anomalies of position (impacted tooth, inverted tooth, tooth migration, partially bony teeth, complete bony teeth); periapical alterations (furcation lesion, circumscribed bone rarefaction); other alterations (radiolucent bone lesions, radiopaque bone lesions, radiopacity in the maxillary sinus, condylar hypoplasia). Differences between groups were tested by the Fisher's exact test and chi-square test (p<0.05). Results For intrarater agreement, Kappa values were 0.76 to 0.85. The presence of supernumerary teeth (p=0.003); conoid teeth (p=0.009); taurodontism (p<0.001); impacted teeth (p<0.001); partial bony teeth (p=0.040); complete bony teeth (p=0.013); and root dilaceration (p=0.047) were statistically more frequent in MPS individuals compared to non-MPS individuals. Bone rarefaction/furcation lesions (p=0.032), condylar hypoplasia (p<0.001), radiolucent bone lesions (p=0.001), and dentigerous cysts (p=0.002) were also more frequent in MPS individuals. Conclusion The presence of specific oral manifestations is more common in MPS individuals than non-MPS individuals.

ABSTRACT

Abstract Objective: To analyze differences in vertical mandibular and trunk symmetry in orthodontic patients. Material and Methods: This was a cross-sectional study of 129 growing orthodontic patients who sought orthodontic treatment at the Dental Hospital Universitas Sumatera Utara, Indonesia. Mandibular symmetry index was observed with pre-treatment panoramic radiography based on Kjellberg's technique and trunk symmetry was evaluated based on questionnaires and visual observation. Vertical mandibular asymmetry was decided if the index of asymmetry was lower than 93.7%. The bivariate analysis used the chi-squared and Fisher's exact tests, with a significance level of 5%. Results: There was a significant association between vertical mandibular and trunk symmetry (p<0.05). The prevalence odds ratio for the association with vertical mandibular asymmetry was 3.007 (95% CI = 1.016-8.905) for trunk asymmetry. Conclusion: The necessity to consider trunk symmetry could be included in orthodontics treatment of any malocclusion with vertical mandibular asymmetry that might require a multidisciplinary approach in the future.

ABSTRACT

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.

ABSTRACT

ABSTRACT Objective: To test the modified Demirjian's method of dental age estimation on the South Indian population and correlate it with the patient's chronological age. Material and Methods: This retrospective radiographic study was performed on digital panoramic radiographs taken during a one-year duration. Radiographs of patients in the age range from 8 to 18 years were included in the study. The radiographs were examined and according to the stage of the crown and root status of the left side mandibular teeth. The stage of calcification was observed for eight teeth in the mandibular arch and was recorded in a specially designed proforma. Each rated tooth with stage was converted into a score using a conversion table specified for girls and boys. Results: 224 digital panoramic radiographs were retrieved from the radiologic database. Out of total study sample, 49.5% (n=111) were boys and 50.5% (n=113). The mean chronological and estimated dental age using dental maturity scores resulted in an overestimation of 3 years and eight months. Also, it was noted that there was a strong positive association between chronological (real) and dental age. Conclusion: It was observed that there was a strong correlation between chronological and dental age. A new formula for determining the chronological age from the estimated dental age was derived. Further studies on a larger population may prove the reliability of this age estimation method.
