Objective: Ultrasound is a non-invasive and low-cost diagnostic tool widely used in medicine. Recent studies have demonstrated that ultrasound imaging might have the potential to be used intraorally to assess the periodontium by comparing it to current imaging methods. This study aims to characterize the repeatability of intraoral periodontal ultrasound imaging.

DSPP is known to be important in the formation of dentin. In DSPP's absence, a severely hypomineralized dentin is formed, in a condition known as dentinogenesis imperfecta (DGI). DSPP has recently been found in several different tissues, including the mandibular condylar cartilage and craniofacial skeleton.
View Article and Find Full Text PDFThe SIBLING proteins are a family of non-collagenous proteins (NCPs) previously thought to be expressed only in dentin but have been demonstrated in other mineralized and non-mineralized tissues. They are believed to play vital roles in both osteogenesis and dentinogenesis. Since they are tightly regulated lifelong processes and involve a peak of mineralization, three different age groups were investigated.

Materials & Methods: This study was a retrospective chart analysis that collected data from the School of Dentistry's Oral Health Clinic at the University of Alberta, Edmonton, Canada. Patients' electronic health records between the years of 2013 and 2019 were analyzed.
Evidence on periodontal education areas in which students have difficulties and their factors are limited. In this study, third- and fourth-year dental students' knowledge was assessed as well as their confidence and ability in five periodontal educational areas using a mixed-method approach. A survey was used to collect data related to history-taking, medical examination, diagnosis, treatment planning, and follow-up.

Materials And Methods: A literature search was conducted across PubMed, Medline via Ovid, Cochrane database, and Google Scholar. The search was completed in September 2020.
Background And Objective: While tobacco cigarette smoking has been proven to be a risk factor for periodontitis, limited information is available regarding vaping, a new alternative to smoking that has been branded as less harmful. Several important in vitro studies have shown that vaping has a similarly damaging effect as cigarette smoking on the health of the periodontium. However, a comprehensive review is lacking in this field.

Background And Objective: Peri-implant tissues appear to exhibit a more vigorous inflammatory response during post-operative healing than periodontal tissues. There is evidence that a single dose of amoxicillin (AMX) prior to implant surgery reduces the risk of early peri-implant healing complications. This study compared the effects of AZM and AMX on neutrophil expression of mRNA for mediators involved in peri-implant healing.

Several new techniques of acceleratory orthodontic treatment have been introduced to effectively treat the malocclusion in a shorter time period with minimal adverse effects.
Objective: The objective of this systematic review is to critically evaluate the potential effect of accelerated surgically assisted orthodontic techniques on periodontal tissues.

Purpose: To assess the prevalence of periodontitis in young populations (previously termed aggressive periodontitis - AgP) and report on the earliest known occurrence of this disease.
Materials And Methods: A search was performed covering the last 18 years utilising the following databases: Medline (Ovid), PubMed and Embase. Four reviewers evaluated each study.
Periodontitis is one of the leading causes of tooth loss in the adult population. This disease can be classified into various categories, and one of the most destructive amongst them is aggressive periodontitis (AgP). The incidence of AgP is lower than other types of periodontitis.

Introduction: This case report describes the management of a patient diagnosed with excessive gingival display caused by altered passive eruption and hyperactive lip. Treatment for this patient was staged and included esthetic crown lengthening and a subsequent lip repositioning procedure.
Case Presentation: A 17-year-old female was referred for assessment of a "gummy smile.
Dentin matrix protein 1 (DMP1) and dentin sialophosphoprotein (DSPP) belong to the Small Integrin-Binding Ligand N-linked Glycoprotein (SIBLING) family. In addition to the features common to all SIBLING members, DMP1 and DSPP share several unique similarities in chemical structure, proteolytic activation and tissue localization. Mutations in, or deletion of DMP1, cause autosomal recessive hypophosphatemic rickets along with dental defects; DSPP mutations or its ablation are associated with dentinogenesis imperfecta.
View Article and Find Full Text PDFObjective: Previous studies have shown that dentin sialophosphoprotein (DSPP) is not only essential to the formation and mineralization of dentin but also plays an important role in forming and maintaining a healthy periodontium. Under physiological conditions, DSPP is proteolytically processed into the NH-terminal and COOH-terminal fragments, and these fragments are believed to perform different functions in the mineralized tissues. Previous studies in our group have demonstrated that the NH-terminal fragment of DSPP inhibits the formation and mineralization of dentin, while the role of this fragment in periodontium is unclear.
View Article and Find Full Text PDFDentin sialophosphoprotein (DSPP) plays a vital role in dentinogenesis. Previously, we showed that, in addition to dentin, DSPP is also highly expressed in alveolar bone and cellular cementum, and plays a crucial role in maintaining periodontal integrity; Dspp-deficient mice demonstrate severe periodontal defects, including alveolar bone loss, decreased cementum deposition, abnormal osteocyte morphology in the alveolar bone, and apical migration of periodontal ligament. Dentin sialophosphoprotein in dentin and bone is cleaved into NH₂ -terminal and COOH-terminal fragments.
View Article and Find Full Text PDFDentin sialophosphoprotein (DSPP) is a large precursor protein that is proteolytically processed into a NH2 -terminal fragment [composed of dentin sialoprotein (DSP) and a proteoglycan form (DSP-PG)] and a COOH-terminal fragment [dentin phosphoprotein (DPP)]. In vitro studies indicate that DPP is a strong initiator and regulator of hydroxyapatite crystal formation and growth, but the role(s) of the NH2 -terminal fragment of DSPP (i.e.

Previous in vitro studies have indicated that DMP1 might regulate the expression of DSPP during dentinogenesis. To examine whether DMP1 controls dentinogenesis through the regulation of DSPP in vivo, we cross-bred transgenic mice expressing normal DSPP driven by a 3.

Previously, we showed that Fam20C conditional knock-out (KO) mice manifest hypophosphatemic rickets, which highlights the crucial roles of this molecule in promoting bone formation and mediating phosphate homeostasis. In this study, we characterized the dentin, enamel, and cementum of Sox2-Cre-mediated Fam20C KO mice.
View Article and Find Full Text PDFDSPP, which plays a crucial role in dentin formation, is processed into the NH(2)-terminal and COOH-terminal fragments. We believe that the proteolytic processing of DSPP is an essential activation step for its biological function in biomineralization. We tested this hypothesis by analyzing transgenic mice expressing the mutant D452A-DSPP in the Dspp-knock-out (Dspp-KO) background (referred to as "Dspp-KO/D452A-Tg" mice).
