Dental maturity is one of the indicators of the craniofacial region growth and development. The aim of the study was to identify and compare dental growth and development in two ethnic groups. The material consisted of 480 orthopantomograms; 240 selected from orthodontic and dental patients from Zagreb (Croatia) and Damascus (Syria) each. Each ethnic group included 120 boys and 120 girls, while the radiographs were classified into 6 groups of 20 each, according to sex and chronologic age (8-13 years). Dental maturity was evaluated by the method of Nolla. The results were statistically analyzed and presented in tables. The subjects from Damascus showed a delay in dental maturity by 1 (girls) to 2 (boys) years compared to the homologous group from Zagreb. The reference values determined in the study may serve as a diagnostic, therapeutic and prognostic tool in the orthodontics and pedodontics of the respective cities.

The present study investigates the potential contribution of Photobiomodulation (PBM) to the regeneration of the bone following the extraction of the first mandibular molar in rats. The study evaluates the efficacy of PBM, using both Low-Level Laser Therapy (LLLT) and Light-Emitting Diode Therapy (LEDT), as promotors of osteoblastic activity and the formation of new bone. Study design, setting, and sample: 45 male Wistar rats were divided randomly into three groups of 15 individuals - (i) control group (left lower molar removed only), (ii) the LLL group (molar removed, followed by LLLT), and (iii) the LED group (molar removed, followed by LEDT).

The mixed dentition stage is a vital period characterized by significant physiological changes, including jaw growth, the development and eruption of permanent teeth, the exfoliation of primary teeth, and the maturation of surrounding soft tissues. These processes collectively ensure functional, esthetic, and stable occlusion. Disruptions during this stage, such as the premature loss of deciduous teeth, can lead to spacing or crowding issues and affect the dental arch length and the position of permanent teeth.

Introduction: Eradication of residual biofilm from root canal dentine is critical for the success of regenerative endodontic procedures (REPs).

The Aim Of The Study: To evaluate the influence of ultrasonically activated irrigants in concentrations used for REPs for removal of dual-species biofilm from three-dimensionally printed tooth models with attached dentine samples.

Methodology: Seventy-two three-dimensionally printed teeth models were fabricated with a standardized slot in the apical third of the root to ensure a precise fit with a human root dentine specimen.

The impact of aging on neutrophil functions and the contribution to periodontitis.

The increasing aging population and aging-associated diseases have become a global issue for decades. People over 65 show an increased prevalence and greater severity of periodontitis, which poses threats to overall health. Studies have demonstrated a significant association between aging and the dysfunction of neutrophils, critical cells in the early stages of periodontitis, and their crosstalk with macrophages and T and B lymphocytes to establish the periodontal lesion.

Volumetric bioprinting of the osteoid niche.

Biofabrication

January 2025

Polymer Chemistry and Biomaterials (PBM) Group, Centre of Macromolecular Chemistry (CMaC), Department of Organic and Macromolecular Chemistry, Ghent University, Krijgslaan 281, Gent, 9000, BELGIUM.

Volumetric bioprinting has revolutionized the field of biofabrication by enabling the creation of cubic centimeter-scale living constructs at faster printing times (in the order of seconds). However, a key challenge remains: developing a wider variety of available osteogenic bioinks that allow osteogenic maturation of the encapsulated cells within the construct. Herein, the bioink exploiting a step-growth mechanism (norbornene-norbornene functionalized gelatin in combination with thiolated gelatin - GelNBNBSH) outperformed the bioink exploiting a chain-growth mechanism (gelatin methacryloyl - GelMA), as the necessary photo-initiator concentration was three times lower combined with a more than 50 % reduction in required light exposure dose resulting in an improved positive and negative resolution.
