Retraction

1. In obstetrics, retraction is the property of the uterine muscles to shorten after their contraction during childbirth. This leads to the gradual advancement of the fetus into the lower part of the pelvic region. At the same time, the basal part of the uterus thickens and begins to pull up the dilated cervix, so that the latter is located above the presenting part of the fetus.

2. In dentistry, retraction is the movement of one or more teeth into a desired position using an orthodontic dental brace. This process allows you to straighten your teeth and correct your bite.

Thus, the term retraction is used in various fields of medicine to refer to the process of tightening or moving tissues and organs into the desired position. In obstetrics we are talking about contracting the uterus, and in dentistry we are talking about straightening teeth using braces.

Retraction in obstetrics

Retraction is the property of the uterine muscles to contract after contraction. This occurs during childbirth and causes the fetus to move into the lower pelvic region. The basal part of the uterus thickens and begins to pull the dilated cervix upward so that it is positioned above the fetus. This helps ensure smooth passage of the fetus through the birth canal.

In dentistry, retraction is used to move one or more teeth into position using orthodontic dental braces. This may be necessary if teeth have been removed or displaced due to injury or illness. An orthodontic brace helps move teeth into position so they are aligned and positioned correctly.

Both examples of retraction illustrate how the use of various techniques can help improve the body's condition and return it to normal functioning.

Editorial responsibility in medicine You already know that assessing the completeness and accuracy of research is one of the important elements of the scientific work of medical researchers. All publications by scientists in scientific journals undergo several stages of control, during which errors are detected, and if they are identified, the publication is retracted. But if the author sees an error in the article, can he cancel his message by simply indicating
