Purpose: This prospective cohort study aimed to 1) determine whether oral hygiene (OH) is a factor affecting orthodontic pain and 2) reveal whether orthodontic pain affects OH practice during orthodontic treatment.
Materials And Methods: 35 adults aged 22-59 years with treated and stabilised periodontitis were recruited. The pre-bonding (baseline) and 1-month post-bonding OH as well as periodontal status were recorded. The experience, duration and maximum intensity of orthodontic pain within the first week after bonding were documented. In addition, the concentrations of cytokines in the gingival crevicular fluid (GCF) were recorded at baseline, 1 day and 1 week after bonding.
Results: Patients who experienced orthodontic pain in the first week of orthodontic treatment had a higher baseline gingival index (GI) than patients who never experienced orthodontic pain (p < 0.05), and patients who experienced a longer duration and higher intensity of orthodontic pain in the first week of orthodontic treatment also had a higher baseline GI (p < 0.05). Patients who experienced orthodontic pain in the first week of orthodontic treatment had statistically significantly higher concentrations of interleukin 1β (IL-1β) in GCF at 1 day post bonding than those who never experienced pain, while baseline GI was positively associated with cytokine concentrations in GCF at 1 week post bonding (p < 0.05). In addition, neither the experience of orthodontic pain nor its duration and intensity were associated with the level of post-bonding OH (p > 0.05).
Conclusions: The finding that increased gingival inflammation accounted for the longer duration and higher intensity of orthodontic pain in treated and stabilised periodontal patient shows that oral hygiene instructions and supportive periodontal care are of great importance prior to and during adjunctive orthodontic treatment in periodontally compromised individuals.

Objective: To evaluate the effects of tinidazole (TNZ) combined with minocycline (MINO) on therapeutic effectiveness, bone resorption, and inflammation in peri-implantitis (PI).
Methods: This retrospective study included 96 PI patients admitted between January 2023 and February 2024. Patients were divided into a control group (n = 46) treated with MINO and a research group (n = 50) treated with TNZ plus MINO.

Background Orthodontic treatment, while primarily focusing on correcting dental alignment and occlusion, has been increasingly validated for its potential impact on broader aspects of oral health and general well-being: its potential influence on body weight. While the mechanical effects of orthodontic appliances are well documented in the literature, their potential behavioral impact on weight loss remains underexplored. Beyond its primary role in correcting dental alignment, our study has unveiled a lesser-known benefit: its potential to aid in weight reduction among individuals who have already struggled through conventional methods.

Objective: Invasive multimodal fMRI in rodents is often compromised by susceptibility artifacts from adhesives used to secure cranial implants. We hypothesized that adhesive type, shape, and field strength significantly affect susceptibility artifacts, and systematically evaluated various adhesives.
Materials And Methods: Thirty-one adhesives were applied in constrained/unconstrained geometries and imaged with T2*-weighted EPI at 7.

Purpose: This cross-sectional study aimed to evaluate the relationship between occipital spur (OS) with both craniocervical posture and craniofacial morphology.
Methods: The study involved 240 lateral cephalograms from subjects with and without OS. The craniocervical posture and facial morphology of every individual were assessed through Uceph software analysis of their cephalograms, considering 32 variables.
