Bruxism is occlusal behaviour that often leads to stomatognathic system overload. Inflammatory markers in the periodontium are detectable in the gingival crevicular fluid (GCF). GCF production fluctuates due to various factors. Our study aimed to assess the effect of tooth clenching or grinding on GCF volume and proinflammatory IL-1β concentration in GCF. This pilot study was carried out on 20 participants aged 21 to 28 with good general health (per 10 people studied and control groups). GCF volume was measured with Periotron 8010 after absorbing for 30 s with PerioPaper strips. Twelve samples were collected from each patient—the buccal and lingual surfaces of teeth 16, 11, 24, 36, 31, and 44 were included. Laboratory examination of IL-1β concentration was performed. In patients with pathological tooth wear, a tendency to increase GCF secretion and IL-1β concentration in GCF was found. GCF volumes were higher in posterior teeth, while IL-1β levels were higher in anterior teeth. Crevices at the molars seem to have a potential predictive value in diagnosing periodontal microinflammation in patients with probable bruxism. Due to occlusal overload, these bruxists are more prone to microinflammatory processes in the periodontium. Further studies in a broader group are required to confirm this correlation.

The buccal fat pad, also called the Bichat’s fat pad (BFP), is an encapsulated fat mass located in the cheek. This type of specialized fat mass can be used both as a pedicular or free graft in various surgeries and approaches. Due to its easy access from the oral cavity approach, it is commonly used for oroantral and palatal fistula closure. The knowledge of its anatomy and surrounding tissues plays a role in its mobilization and suturing onto the desired defect in the palatal or maxillary region. The BFP is mostly associated with the primary approach used for a fistula or bone surgery. Alternatively, the procedure can be performed with a single approach incision, which does not compromise the appearance or the function of the operating or adjacent areas. The most important inclusion criteria for BFP usage and surgical limitations are highlighted. The BFP is used for multiple purposes in reconstructive and oncology surgery and also has its use in esthetic and facial contouring procedures. The amount, volume, and shape of the BFP are mostly associated with the scope of their usage. The aim of the following narrative review is to present the surgical and anatomical implications of fat pads in maxillary and palatal surgeries.

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.
