[Bond strength of metal brackets to enamel with a Russian adhesive complex: an in vitro study].

Background: The era of using adhesives to fix brackets began in the 70s of the last century. There are eight generations of foreign-made adhesive systems for the restoration of teeth. However, until now, in orthodontics, the development of domestic adhesive systems with improved properties of adhesion of brackets to tooth enamel still important, especially in the posterior teeth.

Pain assessment following endodontic treatment using two automated systems compared to manual treatment in primary molars.

Background: Root canal treatment in primary teeth is quite difficult and time-consuming, especially canal preparation. Pain is the most common negative outcome following root canal treatment, occurring hours or days after treatment. It is an unpleasant experience for both the patient and the dentist.

[INFLUENCE OF BEVERAGES ON THE DENTOALVEOLAR SYSTEM (EXPERIMENTAL STUDY)].

The aim of the study was to determine the influence of various drinking liquids on an the dentoalveolar system in rats. The study was carried out on 25 white male rats from the nursery of Krolinfo branch of the Moscow region which were kept in standard vivarium conditions. Age of rats-3-6 months, weight - 150-200 grams.

[Evaluation of the effect of sodium hypochlorite gel on composite bonding strength to enamel of primary teeth after salivary contamination: in vitro study].

Objective: The study investigated the effect of 2%s odium hypochlorite gel application after post-etching salivary contamination on composite bonding strength to primary teeth enamel.

Material And Methods: The sample consisted of 79 primary human teeth that were extracted no more than one month ago. The sample was randomly divided into four groups: (1) the control group (A) comprised 10 primary teeth, and composites were applied in the traditional manner without any salivary contamination; (2) the second group (B) consisted of 23 primary teeth in which salivary contamination was conducted after etching followed by re-etching and follow-up; (3) the third group (C) comprised 23 primary teeth in which saliva contamination was done after etching followed by washing, drying, and follow-up; and (4) the fourth group (D) comprised 23 primary teeth, in which salivary contamination was conducted after etching followed by application of sodium hypochlorite gel and follow-up.

Geolocation data of irrigation network in water user association's operation area under community-based and provider-based network governance.

Massive irrigation development has influenced the way farmers govern water user associations (WUAs) in Klambu Wilalung Irrigation District in Central Java, Indonesia. Recently, farmers adopt community-based () and provider-based () network governance to manage the WUAs. The physical conditions of the irrigation network have become the primary driver of WUA's governance selection.
