Background: The present cross-sectional study was undertaken to evaluate the periodontal and microbiological parameters in patients with surgically repaired unilateral cleft lip and palate (UCLP) undergoing orthodontic correction in comparison to patients without any cleft or orthodontic treatment.
Methods: A total of 120 patients, out of initial 148 patients, between the age group 6 and 18 years were enrolled and divided into four groups with 30 patients each: non-cleft patients without orthodontic treatment in Group 1, non-cleft patients undergoing fixed orthodontic treatment in Group 2, patients with UCLP without any orthodontic treatment in Group 3, and patients with UCLP undergoing fixed orthodontic treatment in Group 4. Periodontal parameters including plaque index (PI), gingival index (GI), gingival bleeding index (GBI), community periodontal index of treatment needs (CPITN) index, pocket probing depth (PD), and tooth mobility were measured in all the groups. The subgingival plaque samples of all the patients were subjected to microbial evaluation using matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF-MS) for clinical diagnosis.
Results: The periodontal parameters were significantly raised in Group 4, followed by Group 3 and Group 2 in comparison to Group 1 (p < 0.01), thereby suggesting poor periodontal health in patients with UCLP undergoing orthodontic treatment. Statistically significant differences (p < 0.01) in counts of micro-organisms among the groups were observed for P. gingivalis, P. intermedia, Veillonella, and Capnocytophaga, with the highest proportions in Group 4, indicating a deteriorating oral health in these patients.
Conclusion: Poor periodontal and microbial health in patients with UCLP undergoing orthodontic treatment indicates a need for reinforcement of oral hygiene practices among these patients.

Objectives: To identify and map the literature on the current state of pH-triggered strategies for resin-based materials used in direct restorative dentistry, focusing on innovative compounds, their incorporation and evaluation methods, and the main outcomes.
Data And Sources: Through a search across PubMed, Scopus, Embase, Web of Science, LILACS, Cochrane Library databases, and Google Scholar, this review identified studies pertinent to pH-responsive dental materials, excluding resin-modified glass ionomer cements.
Study Selection: From the 981 records identified, 19 in vitro studies were included, concentrating on resin-based composite resins (50%), dentin adhesives (25%), and sealants (25%).

Objective: This prospective clinical study examined the effects of fixed orthodontic appliances on oral hygiene and assessed changes in the oral microflora structure of orthodontic patients using high-throughput sequencing technology.
Methods: A total of 45 patients undergoing initial fixed orthodontic treatment were recruited from three hospitals in Beijing, China. Clinical parameters and oral hygiene habits questionnaire were recorded at pre-treatment (T0) and at a 6-month follow-up (T1).

Background: Clear aligner treatment (CAT) has emerged as an effective alternative to conventional multibracket systems in orthodontics. The trimline design and extension of aligners may significantly influence their biomechanical performance and tooth movement efficacy.
Aim: To systematically review the biomechanical effects of different aligner trimline designs and extensions on orthodontic tooth movement.

Background: This case report details a true hemifacial hyperplasia with temporomandibular joint ankylosis case managed through a multidisciplinary approach involving department of oral and maxillofacial surgery, orthodontics, and prosthodontics.
Case Presentation: A 42-year-old female patient presented with a chief complaint of limited mouth opening. Clinically, the patient exhibited severe facial asymmetry due to hyperplasia of the left facial region.
