2. Treatment of peri-implant soft tissue defects: a narrative review
Abstract Soft tissue defects around dental implants, such as papilla or volume loss, peri-implant recession and alterations of the ridge color and/or texture, lead to esthetic and functional complaints. Treatments of these defects in implants are more demanding than in teeth because peri-implant tissue exhibits different anatomical and histological character

3. Extracellular calcium increases fibroblast growth factor 2 gene expression via extracellular signal-regulated kinase 1/2 and protein kinase A signaling in mouse dental papilla cells
Abstract We previously reported that elevated extracellular calcium (Ca2+) levels increase bone morphogenetic protein 2 expression in human dental pulp (hDP) cells. However, it is unknown whether extracellular Ca2+ affects the expression of other growth factors such as fibroblast growth factor 2 (FGF2). Objective: The present study aimed to examine the effe

4. Apexification with white MTA in an immature permanent tooth with dens invaginatus
Dens invaginatus, also known as "dens in dente", is a developmental dental anomaly resulting in an invagination of the enamel organ into the dental papilla. These cases present technical difficulties to the root canal treatment. Apexification using an apical plug of mineral trioxide aggregate (MTA) has been indicated as an alternative to long-term intracanal

5. Dental pulp stem cells express proteins involved in the local invasiveness of odontogenic myxoma
Little is known about the histogenesis of the odontogenic myxoma (OM). Dental pulp stem cells could be candidate precursors of OM because both OM and the dental pulp share the same embryological origin: the dental papilla. For the purpose of comparing OM and stem cells, this study analyzed the expression of two proteins related to OM invasiveness (MMP-2 and

6. Effectiveness of CO2 laser in removal of papillary gingival hyperplasia
INTRODUCTION: Laser applications have increased in a variety of dental procedures, especially in surgeries of soft tissues. Radiation is not invasive and is very well tolerated by tissues. CO2 laser acts in small vessels promoting blood coagulation, making it possible to work in a controlled way. Patients undergoing fixed orthodontic therapy often present in

7. Avaliação histológica e imunolocalização de STRO-1 e BMP-4 em molares de ratos com polpa vital ou necrose pulpar induzida durante o desenvolvimento radicular
Objective: the aim of this study was to characterize the features of live and necrotic dental pulps of molar teeth in rats with developing roots, and to assess the expression of STRO-1 and BMP-4. Methods: twenty-four 4-month-old male Wistar rats were used. To induce necrosis, the pulps of the first lower left molars were exposed to the oral environment. The

8. Efeitos da irradiacao com laser de diodo em dentes de ratos reimplantados tardiamente: analise histometrica / Effects of diode laser irradiation in delayed replanted rat teeth: histometric analysis
Aim: The aim of this study was to evaluate by histometric analysis, the effects of high potency diode laser irradiation in root surfaces of delayed replanted rat teeth. Methods: Sixty Wistar rats were extracted and left on the bench for sixty minutes. Thereafter, the dental papilla was sectioned for pulp removal by a retrograde way, the root canal was prepar

9. Analise do padrão de metilação da região promotora do gene humano PAX9 (-947 - +251) e analise in vitro da sua atividade transcricional / New insights into methylation pattern and transcriptional activity of human PAX9 gene (-947 - +251) in vitro
PAX9 is a key regulator during tooth development and plays an essential role in the patterning of murine and human dentition. In humans, mutations in PAX9 are associated with unique phenotypes of familial tooth agenesis that mainly involve posterior teeth. The objectives of this study were to gain new insights into the transcriptional activity and DNA methyl

10. Relação da distância interimplantar e altura do ponto de contato na formação de papilas gengivais: estudo em cães / Influence of interimplantar distance and height from the point of contact in the formation of gingival papilae: a study in dogs
Os implantes dentais são considerados uma modalidade de tratamento bastante previsível para a reposição de dentes perdidos. Os implantes osseointegráveis principalmente quando colocados em regiões anteriores devem oferecer, além de excelente função, ótima estética, e fonética. Sendo que o critério para o sucesso envolve o estabelecimento do cont

11. Distribuição de MT1-MMP na região odontogenica de incisivos inferiores de ratos em condições funcionais de erupção normal e alterada : estudo imunohistoquimico / MT1-MMP distribuiton in the odontogenic region of lower incisors in rats with normal and altered eruption : an immunohistochemical study
Matrix metalloproteinases (MMPs) are a growing family of endopeptidases that are capable of degrading many structural components of the extracellular matrix, including collagen. MMPs on the dental follicle may be related with remodelation that occurs in this tissue during dental eruption. MT1-MMP has been considered an important membrane-type matrix metallop

12. Expressão imuno-histoquimica de colagenase-1 e gelatinases A e B em mixomas odontogênicos e papilas de germes dentários
The odontogenic myxoma shares cellular and structural aspects with dental papilla, which has been implicated as probable origin of this neoplasm. The aim of the present study was to perform a comparative immunohistochemical analysis for the expression of collagenase-1 (MMP-1) and gelatinases A (MMP-2) and B (MMP-9) in odontogenic myxomas and dental papilla o
