Background and Objectives: The history of facial fillers is very broad, ranging from the use of various materials to modern technologies. Although procedures are considered safe, complications such as skin inflammation, infection, necrosis, or swelling may occur. It is crucial for specialists to be adequately prepared, inform patients how to prepare for corrective procedures, adhere to high safety standards, and continually educate. The goal of this systematic review is to identify complications arising during facial wrinkle correction procedures, as well as to explore safety and potential prevention strategies. Materials and methods: The review of the scientific literature followed the PRISMA guidelines. The search was performed in a single scientific database: PubMed. Considering predefined inclusion and exclusion criteria, articles evaluating the safety of dermal fillers used for facial wrinkle correction, complications, and treatment outcomes were selected. The chosen articles were published from 15 February 2019 to 15 February 2024 (last search date: 25 February 2024). The selected articles compared the complications, product safety, and result longevity of various dermal fillers used for facial wrinkle correction. Results: In thirty-eight articles, which involved 3967 participants, a total of 8795 complications were reported. The majority of complications occurred after injections into the chin and surrounding area (n = 2852). Others were reported in lips and the surrounding area (n = 1911) and cheeks and the surrounding area (n = 1077). Out of the 8795 complications, 1076 were adverse events (AE), including two severe AE cases: mild skin necrosis (n = 1) and abscess (n = 1). There were no cases of vascular occlusion, visual impairment, or deaths related to the performed procedures. A total of 7719 injection site reactions were classified as mild or temporary, such as swelling (n = 1184), sensitivity (n = 1145), pain (n = 1064), bleeding (n = 969), hardening/stiffness (n = 888), nodules/irregularities (n = 849), and erythema (redness) (n = 785). Conclusions: Facial wrinkle correction procedures are generally safe and effective and the results can last from 6 to 24 months, depending on the dermal filler material and its components used. The most common complications after dermal filler injection usually resolve spontaneously, but if they persist, various pharmacological treatment methods can be used according to the condition, and surgical intervention is generally not required.

The alveolar ridge undergoes dimensional changes post-tooth extraction. Studies aim to minimize bone loss and complications by exploring methods to preserve bone height, width, and keratinized tissues. This literature review assesses how primary and secondary intention healing influences alveolar ridge dimensions and bone tissue histomorphometry. Following PRISMA guidelines, a literature search was conducted in PubMed, Cochrane Library, and ScienceDirect databases. This systematic review encompa

Artificial intelligence (AI) is getting more popular in the public and healthcare sectors, specifically in dentistry. Therefore, this systematic review seeks to determine the impact of orthognathic surgery on facial symmetry and explore how AI can be employed in evaluating the changes in a human face. The systematic review was carried out adhering to PRISMA guidelines. This systematic review included three studies (two retrospective studies and one proof-of-concept study) that state that AI is a

Tooth extraction leads to changes in the dimensions of the alveolar ridge, prompting efforts to reduce complications and bone loss. Various strategies have been investigated to preserve bone width, height, and keratinized tissue after extractions. This systematic review analyzes the effect of secondary and primary intention healing on the dimensional changes and histomorphometric properties of the alveolar ridge. In adherence to PRISMA guidelines, a literature search was performed on the Cochrane Library, PubMed, and ScienceDirect databases. This review included randomized controlled trials, retrospective studies, observational studies, split-mouth randomized trials, single-blinded, and controlled clinical trials. Articles published between March 1, 2013, and March 1, 2023, that compared bone changes or histomorphometric data after tooth extraction were included. The risk of bias was assessed using the "Cochrane Collaboration's riskof-bias (RoB 2) tool." A total of 5 studies, involving 92 patients and 128 extracted teeth, were reviewed. The findings showed no significant difference in the resorption of alveolar height and width between the groups treated with primary or secondary intention. Similarly, there were no significant differences in histomorphometric changes between the two healing methods. Therefore, the healing method choice did not significantly affect the dimensional alterations or new bone formation in post-extraction defects.
