Dear followers of Universitas Odontologica,

We want to share with you that we have published two new articles in our volume 40 of 2021 (it does not appear under the current issue, but in past issues).

The first is “X-linked Hypophosphatemia and its Impact on Hard Tissues of the Oral Cavity. An Integrative Review” by Francina Escobar from Colombia.

The second is “Types of Upper Lip Frenulum Insertion Associated with Diastema in 8-to-15-Year-Old Children of Mocha Canton, Ecuador” by Christian Ocaña and Sandra Macías from Ecuador.

Both are published in English, as we have done since mid-2020 in the magazine. We hope you like them.

Sincerely,

Jorge Enrique Delgado, PhD. General editor
