Tooth Surface Reconstruction and Tooth Profile Geometric Analysis of Circular Arc Tooth Trace Cylindrical Gears [PDF]

open access: yes, 2019
To reconstruct the tooth surface of a circular arc tooth trace cylindrical gear (CATT gear), one needs to create an accurate 3D model and investigate geometric features of the tooth profile.

Beyond antimicrobials: Ecological nano‐strategies for rebalancing dysbiotic oral microbial homeostasis

open access: yesBMEMat, EarlyView.
Oral microbial homeostasis, a dynamic host‐microbe balance, is vital in infectious diseases. Conventional antibiotics often disrupt this homeostasis, spurring interest in nanomaterials for oral microbial homeostasis rebalancing. This review outlines nanomaterial strategies across three ecological levels (population/community, ecosystem, and cross ...

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

open access: yesClinical 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 ...

A case series of necrotizing periodontal diseases in hospitalized patients: What hasn't been said yet?

open access: yesClinical Advances in Periodontics, EarlyView.
Abstract Background Necrotizing periodontal diseases (NPDs) are uncommon and severe inflammatory conditions characterized by tissue necrosis, painful ulceration, and rapid clinical progression, frequently associated with systemic immunosuppression. Limited data exist regarding their clinical presentation and management in hospital settings.
