Confirming the impact origin of the São Miguel do Tapuio structure, northeastern Brazil

Meteoritics &Planetary Science, EarlyView.
Abstract The São Miguel do Tapuio structure (SMT) is a remarkable, nearcircular feature of about 21 km diameter, centered at 5°37.6′ S, 41°23.3′ W in Piauí state, northeastern Brazil. The structure is located within the sedimentary strata of the Paleozoic–Mesozoic Parnaíba Basin and predominantly comprises sandstones of the Devonian Pimenteiras and ...

Geophysical investigation of the Santa Marta impact structure—Piauí State, Brazil

Meteoritics &Planetary Science, EarlyView.
Abstract The Santa Marta impact structure in northeastern Brazil, recognized as a partially preserved complex crater, was investigated through an integrated geophysical study employing magnetotelluric (MT) and gravity methods. Our research provides constraints on the crater's subsurface architecture.

Etiology, pathogenesis and treatment of peri‐implantitis: A European perspective

Periodontology 2000, EarlyView.
Abstract Peri‐implantitis is a plaque‐associated pathological condition occurring in tissues around dental implants. It is characterized by inflammation in the peri‐implant mucosa and progressive loss of supporting bone. Over the last 30 years, peri‐implantitis has become a major disease burden in dentistry.

The European contribution to osseous resective surgery for the treatment of residual pockets and furcation defects

Periodontology 2000, EarlyView.
Abstract For decades, osseous resective surgery along with apically positioned flap procedure has been advocated as a predictable treatment option to reduce residual pockets and minimize periodontal complications during supportive periodontal care. More recently, Fiber Retention Osseous Resective Surgery (FibReORS) has been suggested to reduce the ...

The efficacy of biologic factors on the surgical therapy of periodontal suprabony defects: A systematic review and network meta‐analysis of randomized clinical trials

Periodontology 2000, EarlyView.
Abstract Objectives This systematic review investigated the efficacy of biologic factors in the surgical treatment of periodontal suprabony defects. Materials and Methods Three databases were searched to identify RCTs comparing open‐flap debridement (OFD) combined with biologic factors only, or combined with bone substitute, and/or barriers to the same
