Integrative taxonomy supports DNA barcoding in revealing an abundant cryptic species in the United States Coastal Plain

open access: yesJournal of Systematics and Evolution, EarlyView.
We present the most densely sampled phylogeny of Carex section Lupulinae to date (107 specimens) and describe herein a new cryptic species for science from the southern United States, which is locally abundant and found in well‐explored and densely populated areas. Combining DNA sequences with morphometric data obtained from 299 samples, we Demonstrate

Orthodontic management of uneven gingival margins in patients with healthy or reduced periodontium to improve smile aesthetics

open access: yesPeriodontology 2000, EarlyView.
Abstract Uneven gingival margins may cause visible asymmetries during smiling and may reflect alterations in the tooth shape and morphology, particularly in cases requiring restorative procedures. Despite being perceived as a minor health condition, presence of uneven gingival margins usually impacts the smile aesthetics and could affect the individual'

Periodontal and orthodontic management of impacted canines

open access: yesPeriodontology 2000, EarlyView.
Abstract The maxillary and mandibular canines are described by many clinicians as the “cornerstone” of the arch. When in their optimal position, they play a critical role in providing a well‐balanced occlusal scheme that contributes toward functional as well as neuromuscular stability, harmony, esthetics, and dentofacial balance.

Long‐term outcomes of post‐extraction alveolar ridge preservation and alveolar ridge reconstruction followed by delayed implant placement: A systematic review

open access: yesPeriodontology 2000, EarlyView.
Abstract This systematic review analyzed the long‐term outcomes of alveolar ridge preservation (ARP) and alveolar ridge reconstruction (ARR) before delayed implant placement. Eight studies were included (one non‐randomized clinical trial, one prospective case series, four retrospective comparative studies, and two retrospective case series).
