Characterization of stromal calcifications in odontogenic keratocyst: a multicentric study.

Odontogenic keratocysts (OKCs) are locally aggressive cysts that exhibit typical histopathological features and have a propensity for recurrence. Though histological variations are observed in OKCs, hard tissue formation and metaplastic changes are rare, and the underlying pathogenesis is not well understood. This study aimed to characterize stromal calcifications and analyze their association with odontogenic components in non-syndromic and syndrome-associated cases of OKCs.

Comparative evaluation of cleaning efficiency of single file NiTi rotary system during root canal treatment procedure - A scanning electron microscope study.

Background: Optimal biomechanical preparation, thorough irrigation, proper disinfection, and finally, well-sealed obturation is a must to attain definitive success in root canal procedure. Proper preparation of the root canal is all the more imperative to establish a hermetic apical seal with adequately placed filling materials. The present study was conducted for comparing the Cleaning Efficiency of F360 system and the WaveOne Gold (WOG) system of rotary NiTi instrumentation for a root canal.

Methods: A retrospective cross-sectional observational survey was conducted. Four different groups period were studied on patients who visited for dental emergencies at tertiary care centre.

Accuracy of Le Fort I osteotomy with combined computer-aided design/computer-aided manufacturing technology and mixed reality.

The aim of this study was to verify the reproducibility and accuracy of preoperative planning in maxilla repositioning surgery performed with the use of computer-aided design/manufacturing technologies and mixed reality surgical navigation, using new registration markers and the HoloLens headset. Eighteen patients with a mean age of 26.0 years were included.

Secretome proteins regulate comparative osteogenic and adipogenic potential in bone marrow and dental stem cells.

Introduction: Dental stem cells (DMSC) have been studied extensively since their early discovery. However, the data regarding osteogenic potential of DMSC with other cell types is sparse and the secretome proteins underlying these differences have not been explored. In this study, we have compared the osteogenic and adipogenic potential of DMSC with Bone Marrow Stem cells (BMSC) and reported the contribution of secretome proteins in controlling their differentiation.

Molecular spectrum of secretome regulates the relative hepatogenic potential of mesenchymal stem cells from bone marrow and dental tissue.

Liver regeneration is a spontaneous process that occurs after liver injury, but acute liver failure is a complex and fatal disease which is difficult to treat. Cell-based therapies are promising alternative therapeutic approach for liver failure and different cell sources have been tested in this regard. We investigated the comparative hepatogenic potential of human bone marrow stem cells (BMSC) with stem cells derived from human dental pulp (DPSC), apical papilla (SCAP) and follicle (DFSC) during this study.

Overall pattern of publication in Journal of Conservative Dentistry.

Background: The Journal of Conservative Dentistry (JCD) has been online since 2008.

Materials And Methods: This paper reviews the publication in this journal over a 5-year period (2011-2015). It assesses the types of articles published, coverage of various types of subjects of endodontics, and conservative dentistry in the journal and explores the authorship patterns in the publication and citation of the journal over this period.

Secretome Cues Modulate the Neurogenic Potential of Bone Marrow and Dental Stem Cells.

Dental tissue is emerging as a promising source of stem cells especially in nerve regeneration mainly due to their neural origin and ease of harvest. We isolated dental stem cells from three sources, namely, dental pulp (DPSCs), dental follicle (DFSCs), and apical papilla (SCAP), and explored the efficacy of each towards neural differentiation in comparison to bone marrow-derived stem cells. The neural differentiation potential was assessed by expression of various neural markers and neurosphere assay.

Comparison of Root Surface Roughness Produced By Hand Instruments and Ultrasonic Scalers: An Invitro Study.

Background: Instrumentation on tooth surface for debridement of hard and soft debris forms the basis of periodontal therapy. This involves periodic removal of accumulated material using different methods of instrumentation. An ideal instrument should eliminate all the deposits from the root surfaces with no or minimal alteration of the natural morphology.

Karyotype, Pedigree and cone-beam computerized tomography analysis of a case of nonsyndromic pandental anomalies.

This case report presented a karyotype and pedigree analysis of a case with unusual combination of dental anomalies: Generalized short roots, talon cusps, dens invagination, low alveolar bone heights, very prominent cusp of carabelli and protostylid on first permanent molars, taurodontism of second permanent molars, rotated, missing and impacted teeth. None of the anomalies alone are rare. However, until date, nonsyndromic pandental anomalies that are affecting entire dentition with detailed karyotype, pedigree and cone-beam computerized tomography analysis have not been reported.

Effect of uncontrolled freezing on biological characteristics of human dental pulp stem cells.

Human dental pulp stem cells (hDPSCs) hold great promise as a source of adult stem cells for utilization in regenerative medicine. Successful storage and post thaw recovery of DPSCs without loss of function is a key issue for future clinical application. Most of the cryopreservation methods use controlled rate freezing and vapor phase nitrogen to store stem cells.

One of two gbpC gene homologues is involved in dextran-dependent aggregation of Streptococcus sobrinus.

Introduction: Streptococcus sobrinus exhibits marked dextran-dependent aggregation mediated by glucan-binding proteins (GBPs). In contrast to Streptococcus mutans, in which the gbpC gene responsible for dextran-dependent aggregation of this organism has been characterized, genes encoding the S. sobrinus GBPs have not yet been identified.

The effects of tetracycline, minocycline, doxycycline and ofloxacin on Prevotella intermedia biofilm.

Prevotella intermedia, a black-pigmented, anaerobic, gram-negative bacterium, is associated with various type of periodontitis. Antibiotic treatments via a systemic or local route have been reported as being useful for treating periodontal disease. The purpose of this study was to examine the effects of four antibiotics, tetracycline (TET), minocycline (MINO), doxycycline (DOXY) and ofloxacin (OFLX) on P.

Characteristics of myofibres in the masseter muscle of mice during postnatal growth period.

Functional maturation of muscles is related to the constitutional proportion of muscle protein isoforms during development and growth. Although the mouse masseter muscle (MS) is classified as a fast limb muscle, its functions are different from those of a limb muscle. This study investigated the differentiation of myosin heavy chain (MHC) isoforms during the postnatal development periods in mouse MS and mouse tibialis anterior (TA), which is a fast limb muscle.
