AI Article Synopsis
- The study aimed to analyze the prevalence and seriousness of dental misalignment (malocclusion) and the need for braces among high school students in Sana'a city.
- A survey of 1,036 students showed that 38.9% required orthodontic treatment, with a significant portion having conditions like increased overjet and various bite issues.
- Findings suggest a need for a more conservative approach to treating malocclusion in Sana'a's high school populations and indicate a gap in existing research on dental care for adolescents in the area.
Article Abstract
Aims: This study aimed to investigate the incidence and severity of malocclusion and orthodontic treatment needs among randomly selected high school students.
Methods: A multistage stratified random-sampling study was conducted on 1,036 high school students in Sana'a city. The World Dental Federation and World Health Organization method of occlusal traits and the index of orthodontic treatment need were adopted for measurements. Clinically, the molar relationship and facial profile were examined. Assessment of whether examiner or subject perceived the need for orthodontic treatment was made using the esthetic component index. All data were analyzed using the Chi-square test with a significance level of <0.05.
Results: Normal, convex, and concave facial-profile measurements were found in 81.9, 12.1, and 6.15% of sampled students, respectively. Asymmetrical molar relationship was observed in 16.1% of samples, and most of them were of class I/class II relationships. Increased overjet was noticed in 90.9% of students. Anterior crossbite, deepbite, anterior openbite, posterior openbite, posterior crossbite, and scissor bite accounted for 12.2, 12.8, 3.5, 1.3, 6.6, and 0.6%, respectively. According to the index orthodontic treatment need, 38.9% of students needed some form of orthodontic treatment. Among these cases, 24.3% "definitely" needed treatment, and 59.9% of students needed orthodontic treatment.
Conclusion: Our findings suggested a call for a more conservative treatment approach in dealing with malocclusion problems among high school students in all zones of Sana'a governorate, Yemen.
Clinical Significance: A limited number of surveys were performed in Sana'a Governorate to investigate orthodontic treatment needs, facial profiles, and occlusal features among adolescents. The results of this study could guide us to develop a preventive system that minimizes its adverse effects and the need for costly orthodontic treatments.

Introduction: This study aimed to evaluate the stability of palatal rugae patterns after slow maxillary expansion (SME) treatment and the reliability of the rugae region as a reference region in digital superimposition.
Methods: The SME group comprised 21 subjects with Angle Class I or Class II dental malocclusion with unilateral or bilateral crossbite and constricted maxilla and were selected before the pubertal peak. Intraoral scans were captured via the intraoral scanner iTero Element software (version 1.

Clear aligners have transformed orthodontic care by providing an aesthetic, removable alternative to traditional braces. However, their significant environmental footprint, contributing to approximately 15,000 tons of plastic waste annually, poses a critical challenge. To address this issue, advancements in 4D printing have introduced "smart" aligners with shape memory properties, enabling reshaping and reducing the number of aligners required per treatment.

Background: Diseases in humans caused by amphizoic amoebae that can result in visual impairment and even blindness, have recently been identified more frequently worldwide. Etiologically complex incidents of keratitis, including those connected with strains detected in Poland, were evaluated in this study.
Methods: Corneal samples from cases resistant to antimicrobial therapy assessed for epidemiological, microbiological and parasitological aspects were investigated by phase-contrast microscope, slit lamp and by confocal microscopy.

Human dental pulp stem cells (HDPSCs) with multi-lineage differentiation potential and migration ability are required for HDPSC-based bone and dental regeneration. Hispidulin is a naturally occurring flavonoid with diverse pharmacological activities, but its effects on biological properties of HDPSCs remain unknown. Therefore, we investigated the effects of hispidulin on the differentiation potential and migration ability of HDPSCs and elucidated their underlying mechanisms.

Oral diseases, both acute and chronic, of infectious or non-infectious etiology, represent some of the most serious medical problems in dentistry. Data from the literature increasingly indicate that changes in the oral microbiome, and therefore, the overgrowing of pathological microflora, lead to a variety of oral-localized medical conditions such as caries, gingivitis, and periodontitis. In recent years, compelling research has been devoted to the use of natural antimicrobial peptides as therapeutic agents in the possible treatment of oral diseases.
