Objective: This study aimed to compare the effects of orthodontic treatment on the same patients using aligners (upper arch) versus traditional fixed appliances (lower arch) on oral hygiene and periodontal health. Materials and Methods: A total of 90 patients, all treated by the same orthodontist and with an average age of 26 years, were included in the study. The research focused on factors predisposing patients to periodontitis, as well as plaque and tartar accumulation. Statistical analysis was performed using the paired-samples Student’s t-test, with values of p < 0.05 deemed statistically significant. Results: Patients treated with fixed orthodontic appliances generally showed increased plaque accumulation (+10% PI) and a decline in periodontal health compared to those treated with aligners (40% presented a high level of S.Mutans and Lactobacilli). In patients who did not maintain proper oral hygiene, the initial conditions of the upper arch remained stable, while the lower arch exhibited significant deterioration, with increased plaque buildup and greater tissue inflammation. Conclusions: The findings emphasize the critical role of individual oral hygiene practices during orthodontic treatment in preserving periodontal health. Aligners appear to be more favorable in protecting periodontal tissues, improving plaque control, and reducing gingival inflammation. Various supplementary approaches for plaque management and microbial colonization in saliva should be implemented based on the type of orthodontic appliance used.

Trauma is a worldwide cause of millions of deaths and severe injuries every year, all over the world. Despite the limited extension of the oral region compared to the whole body, dental and oral injuries account for a fairly high percentage of all body traumas. Among head and neck traumas, dental and facial injuries are highly correlated to sport activities, and their management can be a real challenge for practitioners of any specialty. In case of trauma directed to periodontal structures, restorative and endodontic solutions may not be sufficient to achieve a definitive and long-lasting treatment. This article aims to illustrate surgical options and appliances to prevent dental injuries that may be available to the clinicians treating dental trauma involving oral soft and hard tissues.

The purpose of this literature review was to evaluate the effectiveness of the laser-assisted treatment of dentinal hypersensitivity. A review with inclusion and exclusion criteria was performed from January 2009 to December 2014 with electronic data-bases: MedLine via PubMed, Science Direct and Cochrane Library. Research of paper magazines by hand was not considered. Forty-three articles were selected between literature reviews, in vitro studies, clinical trials, pilot and preliminary studies. The items were divided into laser-used groups for an accurate description, and then the reading of results into various typologies. Laser-assisted treatment reduces dentinal hypersensitivity-related pain, but also a psychosomatic component must be considered, so further studies and more suitable follow-ups are necessary.

Background: Impaction of maxillary canines is a frequent clinical challenge in orthodontics. Early diagnosis is key to effective management. Methods: This narrative review included studies published from 2004 to 2024. An electronic search was conducted in PubMed, Scopus, and Google Scholar (September–November 2024), using predefined eligibility criteria. The selection and drafting were completed in the following months. Studies involving orthopedic, orthodontic, or surgical-orthodontic management of impacted maxillary canines were included. Case reports and procedures limited to avulsion or transplantation were excluded. Results: A total of 10 studies were analyzed, comprising 5529 patients, of whom 2530 met the criteria for treatment-specific analysis. Surgical exposure with orthodontic traction was the most frequent treatment (72%), followed by monitoring (12%), maxillary expansion (6%), and extractions (10%). Interceptive approaches were mainly applied in patients aged 7–18 years, with favorable outcomes especially before age 12. In adults, more invasive treatments were required, often with reduced success rates. Conclusions: Early diagnosis and interceptive extraction of deciduous canines reduce treatment complexity and improve success. Therapeutic outcomes are strongly influenced by patient age, tooth position, and angulation. A structured, radiographically guided approach, supported by the proposed decision-making flowchart, may optimize clinical outcomes. However, heterogeneity of included studies and lack of long-term follow-up limit the strength of available evidence.

Background: Traumatic dental injuries (TDIs) are a common complication in sports, with an overall prevalence ranging from 0.71% to 60%. Kickboxing is a high-risk combat sport for trauma to the facial region. Methods: A total of 142 5-to-65-year-old amateur athletes participated in the survey with a questionnaire that was released during their regular practice days. The questionnaire was structured into three parts: (1) questions about age, gender, type, and time of sports practice; (2) questions about dental injuries, personal experience, and awareness of emergency management, particularly about tooth avulsion; (3) questions about wearing a mouthguard for TDI prevention. Results: A total of 13 percent of athletes suffered a TDI while training or fighting. Regarding first aid, 61% of the participants in this survey are aware of the possibility of replanting a tooth after its avulsion; 10% believe that the tooth should be replanted within 15 min, and 37% of athletes believe that it should be kept wet. The mouthguard is known to the majority of athletes (94%), and 66% were informed by the coach; 68% of the athletes use it. Seventy-four percent of the mouthguards were purchased in a sports shop. Conclusions: A relatively low prevalence of TDIs was observed in players in the sample. A lack of information about the emergency management of tooth avulsion and about the type of mouthguard to wear emphasizes the importance of educational training by dentists to athletes and coaches.
