Risk prediction model of impacted supernumerary tooth-associated root resorption in children based on cone-beam computed tomography analysis: a case control study

BMC Oral Health
Background External surface resorption is pressure-induced resorption and occurs on the external surface of the root, pressure exerted by impacted teeth, is common causes of external surface resorption.

Redescription of †Eobrasilia coutoi (Metatheria: Polydolopimorphia), a unique sclerocarpophagous metatherian from the Palaeogene of South America: Systematic affinities, and paleoecological and evolutionary implications

The Anatomical Record, EarlyView.
Abstract The ‘Palaeogene strata’ of the Itaboraí Basin (upper Paleocene‐lower Eocene), Southeastern Brazil, has preserved 29 genera and almost 50 species of metatherians (about 65% of its mammalian diversity). Among them, Eobrasilia coutoi Simpson, 1947 is the most enigmatic due to its quite fragmentary nature.

Dissecting the dissection laboratory: Elements for designing a human anatomy laboratory

Anatomical Sciences Education, EarlyView.
Abstract The human anatomy dissection laboratory is a critical component of anatomical and medical education. Development, maintenance, and stocking of these laboratory spaces have unique demands, with all of the challenges in running a laboratory with Biosafety Laboratory Level 2 (BSL‐2) classification, housing a large volume of tissues saturated with

FAM20B-catalyzed glycosaminoglycans control murine tooth number by restricting FGFR2b signaling

BMC Biology, 2020
Background The formation of supernumerary teeth is an excellent model for studying the molecular mechanisms that control stem/progenitor cell homeostasis needed to generate a renewable source of replacement cells and tissues.

Tooth autotransplantation following extraction of periodontally hopeless teeth in a periodontitis patient

Clinical Advances in Periodontics, EarlyView.
Abstract Background The aim of the study is to report clinical outcomes of autogenous tooth transplantation (ATT) of fully developed third molars following the extraction of periodontally hopeless teeth as a part of the treatment of a stage III, grade C, molar‐incisor pattern (MIP) periodontitis case.

Bimanual instrument suturing technique for periodontal and implant microsurgery: A technical note

Clinical Advances in Periodontics, EarlyView.
Abstract Background In the traditional suturing technique, the dominant hand (DH) holds a needle holder, and the non‐dominant hand (NH) performs manual ties without the aid of an instrument. In periodontal and implant microsurgery, finer sutures and needles, e.g., 7‐0 in International Organization for Standardization units, are used, which could be ...

Combining the tunneled coronally advanced flap (TCAF) with internal frenectomy–vestibular incision subperiosteal tunnel access (IF‐VISTA) for the treatment of mandibular anterior gingival recessions: A technique report

Clinical Advances in Periodontics, EarlyView.
Abstract Introduction Gingival recession (GR) defects in the mandibular anterior region represent a particularly challenging scenario in periodontal plastic surgery, owing to a thin soft tissue phenotype, minimal keratinized tissue, limited vestibular depth, and the frequent presence of a prominent labial frenum.
