Tooth loss and depression in Chilean participants of the National Health Survey 2016-2017: Oral and social functions mediation analysis.

Background: Previous studies have indicated the association between poor oral health and depression in adults. This study evaluated oral and social functions contribution to the association between tooth loss and depressive symptoms in Chilean individuals.

Methods: We used data from the Chilean National Health Survey.

5-year clinical performance of posterior bulk-filled resin composite restorations: A double-blind randomized controlled trial.

Objectives: The aim of this double-blind, and randomized controlled clinical trial was to evaluate the 5-year clinical performance of posterior resin composite restorations placed with the incremental filling technique [IF] or the bulk-fill technique [BF]. Two different adhesive systems were used: etch-&-rinse (ER) or self-etch (SE).

Methods: Posterior dental teeth of 72 participants (n = 236), with a cavity depth of at least 3 mm, were randomly divided into four groups.

Striated muscle involvement in experimental oral infection by herpes simplex virus type 1.

Herpes simplex virus type 1 is one of the most frequent causes of oral infection in humans, especially during early childhood. Several experimental models have been developed to study the pathogenesis of this virus but all of them employed adult animals. In this work, we developed an experimental model that uses mice younger than 4 days old, to more closely resemble human infection.
