Introduction. The severity of facial wrinkles is related to many factors, such as: endogenic skin aging (innate mechanisms), the influence of external factors (photoaging) and lifestyle factors such as smoking or body weight.Aim. The aim of the study is to determine the relationship between BMI and the occurrence of various types of facial wrinkles.Material and Methods. 50 people participated in the study, including 9 men and 41 women. The criteria for participation in the study were: age over 18, no visible facial hair, no makeup. Each volunteer had their weight and height examined — BMI was determined and 6 extraoral photographs were taken. The severity of wrinkles in 9 facial areas was analyzed, and their severity was assessed on the basis of a photographic scale by three independent researchers. The obtained data were analyzed statistically. The adopted limit of statistical significance was p <0.05.Results. There was a statistically significant correlation between BMI and the severity of mouth angle wrinkles.Conclusions. The relationship between BMI and the severity of the wrinkles of the mouth angle may be determined by the weight of the subcutaneous tissue around the mouth angle, however, it requires more detailed research.

Botulinum toxin, produced by the bacteria Clostridium botulinum, paralyzes muscle contraction by inhibiting the conduction of nerve impulses. Injections of the preparation are widely used as a non-surgical method of improving the face appearance. The mentalis muscles and the surrounding soft tissue are considered key structures in lower facial rejuvenation treatments.The ability to precisely locate the muscle is a challenge for every doctor who performs treatments with the use of neurotoxin and determines therapeutic success. The muscle extends 5–10 mm from the midline and 20–30 mm from the horizontal line joining the mouth, and is present at a depth of 6.7–10.7 mm under the skin. Typically, a single midline injection of 4 to 10 units of onobotulin, incobotulin, parabotulin or 12–30 U of abobotulin is sufficient. Two injections laterally from the center of the chin are allowed, using 4–5 units of the toxin (12–15 U for abobotulin). The aim of the article is to review the use of neurotoxin injection into the mental muscle in aesthetic medicine procedures.

Transmigracja kła dolnego jest rzadką anomalią zębową polegającą na przekroczeniu przez kieł linii pośrodkowej żuchwy. Wśród metod leczenia wymienia się: ekstrakcję zęba zatrzymanego, autotransplantację lub ortodontyczne wprowadzenie zęba do łuku zębowego. W przypadku opisanej pacjentki podjęto decyzję o ortodontycznym wprowadzeniu zęba zatrzymanego do łuku. Za podjęciem leczenia przemawiała dobra współpraca z rodzicami, stopień I zatrzymania kła według Mupparapu, a także bezpieczna odległość od korzeni zębów sąsiednich.

A gummy smile is an excessive exposure of the gums while smiling. There are four types: anterior- excessive gum exposure from canine to canine, posterior — excessive gum exposure in the lateral segment, mixed — combining the anterior and posterior components, and asymmetrical — with a disproportion between the right and left side. The causes of gingival smile include: skeletal defect, delayed passive tooth eruption, nasal septal dysplasia, and excessive muscle activity. A simple, fast and minimally invasive method of gummy smile therapy caused by excessive muscle activity is the supply of botulinum toxin type A to the muscles responsible for a given type of smile. A favorable aesthetic effect can be achieved with a good knowledge of application sites and individually selected doses. When determining the dose, which is described in the literature between 2 IU and 10 IU onabotulin per page, researchers take into account not only the type of corrected smile, the number of puncture points, but also gender and age of the patient.

The harmony of the smile depends not only on the dentition, but also on the gum tissue, which excessively exposed can negatively affect aesthetics of the smile. Exposure of a small amount of gum during a smile is acceptable however a smile in which the exposure of the gum is more than 2 mm is considered an aesthetic defect called gummy smile. Among the causes of gingival smile listed are: shortened or hyperactive upper lip muscles (levator labii superioris, levator labii superioris alaeque nasi, zygomatic minor muscles), vertical maxillary excess, extrusion of alveolar ridges, altered passive eruption. In the case of hyperactive upper lip muscles, botulinum toxin can be used — this procedure was used in the described cases, and the effects were assessed using the FotoMedicus system and measurements of gingival exposure. In first case Bocouture botulinum toxin was administered on both sides, 4 units bilaterally in the levator labii superioris muscle and 2 units into levator anguli oris muscle. In total, 12 units were given. During the follow‑up the patient reported the start of the effect from the 5th day after the supply with the maximum effect after 12 days. A 6 mm correction of gummy smile was achieved. In the second case 4 units of botulinum toxin were applicated bilaterally into levator labii superioris alaeque nasi muscle. A 3 mm correction of gummy smile was achieved. The aesthetics of the face in a smile definitely improved in both men.
