Different approaches and effectiveness in orthodontic traction of impacted cani...
Carvalho, João; Amaral, Rui; Rocha, Ana Sofia; Pinho, TeresaCanines have a fundamental role in the dental arch, both aesthetically and functionally. Apart from the third molars, maxillary canines are the most frequently impacted teeth. Orthodontic traction of an impacted canine is one of the most appropriate approaches when there is a good prognosis, in growing patients and without a serious lack of space in the arch. This systematic review aims to describe the differen...
Influence of ultrasound stimulation on the viability, proliferation and protein...
Pascoal, Selma; Oliveira, Sofia; Monteiro, Francisca; Padrão, Jorge; Costa, Rita; Zille, Andrea; Catarino, Susana Oliveira; Silva, Filipe S.Among the adjunctive procedures to accelerate orthodontic tooth movement (OTM), ultrasound (US) is a nonsurgical form of mechanical stimulus that has been explored as an alternative to the currently available treatments. This study aimed to clarify the role of US in OTM by exploring different stimulation parameters and their effects on the biological responses of cells involved in OTM. Human fetal osteoblasts a...
Development and validation of an on-line SPE coupled to liquid chromatography w...
Prost-Tournier, Oséa; Rocha, Lígia; Pinho, Teresa; Tiritan, Maria Elizabeth; Gonçalves, VirgíniaBackground: Resin-matrix composites, commonly used in dentistry, often contain derivatives of Bisphenol A (BPA) such as Bisphenol A-Diglycidyl Methacrylate and Bisphenol A-Dimethacrylate in their organic matrix composition [1]. Although BPA is not a direct ingredient of these composites, it may be present as a contaminant or degradation product, potentially released into the oral cavity following dental restora...
Efficiency and predictability of maxillary expansion with Invisalign® system
Rocha, Ana Sofia; Gonçalves, Maria; Oliveira, Ana Catarina; Pinho, TeresaThe Invisalign® system aims to ensure aesthetics and achieve positive clinical results; however, its efficacy is still debatable. Along with lower incisor intrusion and upper molar distalization, arch expansion is one of the most predictable movements that may be achieved using clear aligners. This makes the system a conceivable method for the correction of crowding and posterior dentoalveolar crossbites. The a...
Coronal repercussions of maxillary central incisor torque with clear aligners –...
Oliveira, Ana Catarina; Rocha, Ana Sofia; Sousa-Santos, Primavera; Pinho, TeresaRecent years have witnessed a big evolution of clear aligner technology, due to the growing importance of aesthetics and comfort. An adequate coronal torque value has a significant impact on smile aesthetics and on the patient’s soft tissue profile. The aim of this systematic review is to evaluate the current knowledge about the efficacy of the maxillary central incisor coronal torque in the InvisalignÒ system....
Three-dimensional evaluation of impacted maxillary canines and repercussions on...
Leitão, Rita; Rocha, Ana Sofia; Oliveira, Ana Catarina; Peres, Ana Luísa; Pinho, TeresaMaxillary canines have very important roles in aesthetics and function. They are the second most frequently impacted teeth. One of the most severe complications associated with impacted maxillary canines is root resorption of adjacent teeth. Cone-beam computed tomography (CBCT) provides three-dimensional multiplanar images and detailed information on dentofacial structures. The aim of this systematic review is ...
Optimization of a photobiomodulation protocol to improve the cell viability, pr...
Gonçalves, Aline; Monteiro, Francisca Machado; Oliveira, Sofia; Costa, Inês; Catarino, Susana Oliveira; Carvalho, Óscar Samuel Novais; Padrão, JorgeNumerous pieces of evidence have supported the therapeutic potential of photobiomodulation (PBM) to modulate bone remodeling on mechanically stimulated teeth, proving PBM's ability to be used as a coadjuvant treatment to accelerate orthodontic tooth movement (OTM). However, there are still uncertainty and discourse around the optimal PBM protocols, which hampers its optimal and consolidated clinical applicabili...
Masticatory function in individuals with temporomandibular disorders: a systema...
Marcelino, Vanessa; Rovere, Solene de; Paco, Maria; Gonçalves, Maria dos Prazeres; Marcelino, Sandra Andreia; Guimarães, Antonio Sergio; Pinho, TeresaThe literature search was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) protocol in the PubMed, Cochrane Library, LILACS, EBSCO, Scielo, between 2012 and 2022. The methodological quality was assessed by using the Newcastle-Ottawa Study Quality Assessment Scale. Mean differences and 95% confidence intervals were calculated and combined in meta-analyses. A ...
Occlusal changes with clear aligners and the case complexity influence: a longi...
Marcelino, Vanessa; Baptista, Sofia; Marcelino, Sandra Andreia; Paco, Maria; Rocha, Duarte; Gonçalves, Maria dos Prazeres; Azevedo, RuiBackground: Clear aligners (CA) are used 22 h daily, creating a bite-block effect. This work aims to (i) analyze occlusal changes before the beginning of treatment, after the first set of CA and after the use of additional aligners; (ii) compare planned occlusal contacts with the ones obtained after the first set of CA; (iii) analyze the occlusal changes occurred after reaching the orthodontic goals after 3 mon...
Interceptive treatment with Invisalign® First in moderate and severe cases: a c...
Pinho, Teresa; Rocha, Duarte; Ribeiro, Sofia; Monteiro, Francisca Machado; Pascoal, Selma; Azevedo, RuiThe increasing demand for more aesthetic/comfortable orthodontic alternatives fostered the utilization of clear aligners in recent years. However, the efficacy of clear aligners for treating complex malocclusions is often treated with scepticism. This case series aims to evaluate the predictability of the Invisalign<sup>®</sup> First system in moderate and severe cases requiring interceptive orthodontic treatme...
