13. 3D comparison of dental arch stability in patients with and without cleft lip and palate after orthodontic/rehabilitative treatment
Abstract This study aimed to compare the linear dimensions of the dental arches of adult patients with complete unilateral cleft lip and palate (UCLP) after orthodontic and prosthetic treatment with fixed partial dentures (FPD) to patients without clefts, using 3D technology. This retrospective longitudinal study sample consisted of 35 subjects divided into

14. Peripheral odontogenic fibroma in the mandibular gingiva: case report
RESUMO Fibroma odontogênico periférico (FOP) é uma neoplasia benigna rara, de origem mesenquimal odontogênica, representando aproximadamente 4,7% de todos os tumores odontogênicos. Este artigo relata o caso de uma mulher de 29 anos de idade que se apresentou com um nódulo avermelhado, indolor, na gengiva mandibular vestibular direita, entre o segundo p

15. Comparison of dentoskeletal and soft tissue effects of Class II malocclusion treatment with Jones Jig appliance and with maxillary first premolar extractions
Resumo Objetivo: o objetivo desse estudo foi comparar as alterações cefalométricas em pacientes com má oclusão de Classe II, divisão 1, tratados com o aparelho Jones Jig ou com extrações dos primeiros pré-molares superiores. Métodos: a amostra consistiu de 88 telerradiografias laterais de 44 pacientes, que foram divididos em dois grupos. O Grup

16. Effect of different stripping techniques on pulpal temperature: in vitro study
RESUMO Introdução: o desgaste proximal do esmalte é um procedimento clínico rotineiro utilizado na Ortodontia para se criar espaços ou equilibrar discrepâncias de tamanho dentário. Esse procedimento pode resultar em transferência de calor para a polpa, predispondo-a a mudanças histopatológicas e necrose do tecido pulpar. Objetivo: medir as mudan

17. Maxillary sinus floor pneumatization and alveolar ridge resorption after tooth loss: a cross-sectional study
Abstract This is a cross-sectional study that aimed to estimate maxillary sinus floor (MSF) pneumatization in single missing tooth of posterior maxilla, by using cone-beam computed tomography (CBCT). CBCT images were analyzed bilaterally and divided into 2 groups: edentulous site (EdS) - edentulous single region of upper second premolar, first or second mola

18. Maxillomandibular giant osteosclerotic lesions
Abstract Giant Osteosclerotic Lesions (GOLs) are a group of rarely reported intraosseous lesions. Their precise diagnosis is important since they can be confused with malignant neoplasms. Objective This retrospective study aimed to record and analyze the clinical and radiographic Giant Osteosclerotic Lesions (GOLs) detected in the maxillomandibular area of

19. The Search for the Centre of Resistance of a Tooth Using a Finite Element Model and the Continuum Mechanics
Abstract In orthodontics, the CR is defined as the ideal point for the positioning of the bracket. This paper presents numerical analyses of a premolar tooth, which aim at searching the centre of resistance (CR) by applying several external torques. We built the geometry of the tooth by making a tomographic renderisation with the software MIMICS. The numeric

20. Finite element simulation of fracture in a restored premolar tooth using high aspect ratio elements
Abstract Introduction The term cracked tooth syndrome refers to an incomplete fracture of a vital posterior tooth that involves the dentin and occasionally extends into the pulp. There is a very limited number of publications trying to model dentin crack growth using numerical techniques. Therefore, it is essential to numerically model this phenomenon in o

21. Evaluation of adaptation of ceramic inlays using optical coherence tomography and replica technique
Abstract Optical coherence tomography (OCT) has generally been used as a nondestructive technique to evaluate integrities of composite restorations. We investigated marginal and internal adaptations of ceramic inlay restorations with OCT and compared them to results with the silicone replica technique. Round-shaped class I cavities were prepared on 16 human

22. Clear cell odontogenic carcinoma of the mandible: a treatment strategy
Abstract Clear cell odontogenic carcinoma (CCOC) is a rare odontogenic tumor of the jaws, histologically characterized by the presence of agglomerates of cells with eosinophilic cytoplasm. The patient, a 62-year-old Caucasian woman, presented an intraosseous lesion in the mandibular symphysis. A clinical examination revealed a discrete volumetric increase wi

23. Evaluation of miniscrew angulation in the posterior maxilla using cone-beam computed tomographic image
RESUMO Objetivo: o presente estudo objetivou avaliar se alterações no ângulo de inserção do miniparafuso são um fator decisivo para a adaptação do corpo do parafuso em áreas com espaço inter-radicular aumentado, na região posterior da maxila. Métodos: foram realizadas análises em 60 quadrantes maxilares posteriores, a partir de imagens obtid

24. Apical Negative Pressure irrigation presents tissue compatibility in immature teeth
Abstract Aim: To compare the apical negative pressure irrigation (ANP) with conventional irrigation in the teeth of immature dogs with apical periodontitis. Methods: Fifty-two immature pre-molar root canals were randomly assigned into 4 groups: ANP (n=15); conventional irrigation (n=17); healthy teeth (control) (n = 10); and teeth with untreated apical per
