Background: The aim of this study was to investigate the influence of BMI on the timing of permanent tooth emergence in Czech children.
Objectives: In this cross-sectional study, 1370 Czech children were examined. The age, gender, weight, height, all emerged permanent teeth (except third molars) of each child were all recorded. A tooth is defined as having emerged when at least any part of it has penetrated the gingiva.
Methods: A logistic regression model was used to calculate the median emergence age per tooth for both genders separately and BMI was used as a factor variable to detect statistically significant differences in the times of tooth emergence within pairs of BMI groups. The data were statistically processed using IBM SPSS Statistics 23 (SPSS Inc., Chicago, IL).
Results: Statistically significant differences were found for the following permanent teeth (using the FDI two-digit system): 13, 14, 15, 16, 17, 41, 44, 45, 46, 47, 33, 35, 37, 21, 24, 25, 26, 27 for girls and 12, 13, 14, 15, 16, 41, 43, 44, 45, 22, 25, 32, 34, 35, 36 for boys. These teeth were observed to emerge earlier in obese children. A similar correlation (although not statistically significant) was observed between the time of emergence of the remaining teeth and the BMI of the child.
Conclusion: The data in this research highlight significant differences in emergence times of permanent teeth due to the influence of BMI in Czech children. These findings are important for dental treatment planning.

Dental anomalies are frequent in boars and pigs, and they generally affect the first premolar loci. The prevalence of these dental anomalies was investigated in a large number of populations around the world. These studies mainly focused on the influence of domestication, size, sexual dimorphism or food hardness on these anomalies.

Eating behavior stands as a fundamental determinant of animal survival and growth, intricately regulated by an amalgamation of internal and external stimuli. Coordinated movements of facial muscles and the mandible orchestrate prey capture and food processing, propelled by the allure of taste and rewarding food properties. Conversely, satiation, pain, aversion, negative emotion or perceived threats can precipitate the cessation or avoidance of eating activities.

Minimally invasive dentistry (MID) has revolutionized pediatric dental care by emphasizing the preservation of healthy tooth structures, reducing treatment-related trauma, and improving patient compliance. This narrative review explores advancements in MID techniques, including silver diamine fluoride (SDF), resin infiltration, atraumatic restorative treatment (ART), bioactive materials, laser-assisted therapies, and three-dimensional (3D) printing technologies. These approaches prioritize early diagnosis, prevention, and conservative management, aligning with patient-centered and sustainable practices.

Nanohydroxyapatite (nHA) is distinguished by its exceptional biocompatibility, bioactivity and biodegradability, qualities attributed to its similarity to the mineral component of human bone. This review discusses the synthesis techniques of nHA, highlighting how these methods shape its physicochemical attributes and, in turn, its utility in biomedical applications. The versatility of nHA is further enhanced by doping with biologically significant ions like magnesium or zinc, which can improve its bioactivity and confer therapeutic properties.
