Summary: The study examined the clinical behavior of four dental sealants on first permanent molars in children, finding that applying sealant around the age of 7 is more effective. Different sealant materials showed varying retention rates at 6, 12, and 18 months intervals, providing choices for practitioners.

Summary: Analyzing dental wear patterns using digital methods can provide insights into an individual's chewing efficiency and functional changes. This study on Australian Aboriginal children found that the occlusal dynamics remained relatively consistent as they grew, suggesting stable masticatory function over time.

Summary: This study aims to understand the genetic architecture of crown morphology in the human diphyodont dentition. The results suggest that there are different genetic correlations between deciduous and permanent molars, and that m2 represents the anterior-most member of a true molar field.

Summary: Morphology can predict ecological roles, such as diet, for taxa without direct observations. Traditional diet categories may oversimplify analyses, but Bayesian multilevel modeling can accurately predict the importance of food items based on dental morphology and body size. This approach offers new insights into the dietary niches of extant and extinct carnivoran species and can be applied to predicting multivariate ecology from phenotypic traits.

Summary: Dental microwear texture analysis (DMTA) is commonly used to assess the dietary ecology of modern and fossil taxa. This study focused on analyzing the teeth of the Tasmanian devil and found that teeth with similar morphologies have similar functions and dietary records. Additionally, comparing fossil and modern specimens indicated a consistent consumption of foods with similar textures since the late Quaternary.

Summary: This study found a higher frequency of hypomineralized second primary molars (HSPM) in children with molar incisor hypomineralization (MIH). However, there was no correlation between the severity of MIH and the presence of HSPM. HSPM may serve as a predictor of MIH.

Summary: The study used CBCT data to investigate the anatomical relationship between the mandibular molar and alveolar bone for the design of implant restoration. Results showed no significant differences in morphology between the left and right lower first molars, with morphology classified into straight, oblique, and concave types. The proposed classification provides evidence for appropriate selection and design of mandibular molar implants, with the concave type posing the highest risk of lingual perforation.

Summary: Understanding the relationship between form, function, and diet is crucial for studying the roles and adaptive responses of organisms in their ecosystem. However, analyzing this relationship in invertebrates has been difficult due to a lack of quantitative methods. This study tests the effectiveness of dental topographic metrics in quantifying form in invertebrate mandibles and assessing their relationship with diet. The results show that these metrics successfully capture the relationship between diet and dental tool morphology and can be used to predict dietary differences in orthopterans.

Summary: Increased human presence in the Arctic may impact its vulnerable ecosystems, including the Arctic and red foxes. A study conducted on Arctic foxes in proximity to human settlements found that there was a significant decrease in tooth wear and breakage, indicating a dietary shift towards softer human-derived foods.

Summary: Fossil primate dietary inference is enhanced through multiple proxies such as dental topography and wear measurement. In this study, convex Dirichlet normal energy was used to assess tooth use and function in two fossil anthropoid taxa and four extant platyrrhine taxa. The results suggest that both fossil taxa exhibited similar topographic changes with wear as a frugivorous extant platyrrhine and supported the previous suggestion of hard-object feeding in their dietary ecology. The study provides valuable insights into the diet of these ancient primates.

Summary: This study utilizes 3D models and quantitative tooth form data to reclassify the dietary ecology of extant strepsirrhine primates, with a focus on extinct species. The research suggests that many subfossil lemurs and basal fossil strepsirrhines were primarily frugivorous or gummivorous.

Summary: This study evaluated the radiographic features of inactive enamel caries lesions in permanent molars and found that lesions with radiolucency at baseline were more likely to progress over 4-5 years. The presence of radiolucency at baseline was a predictor of caries progression, indicating the importance of closer monitoring for such lesions. The use of bitewing radiographs can help identify surfaces/lesions more likely to progress and establish proper recall intervals for patient monitoring.

Summary: In this study, several accurate dental age estimation methods were used to evaluate children with molar-incisor hypomineralization (MIH). The results showed that MIH does not affect dental age and tooth development, as there was no significant difference in dental age estimation between groups with and without MIH.

Summary: Our understanding of primate adaptive evolution depends on understanding the relationship between dental functional morphology and dietary ecological constraints. This study explores the relationship between wear-related dental functional morphology and dietary habits within the Papionini tribe. The results show that different species of primates have different dental topographies that reflect their dietary specializations.

Summary: The impact of exogenous grit on dental microwear patterns is a result of dynamic and complex interactions between factors such as grit size, food material properties, and feeding time, providing further evidence of the multifactorial nature of dental microwear formation.

Summary: This study in southwestern Madagascar provides new paleontological and paleoclimatological data to understand Late Holocene changes in faunal assemblages and hydroclimate variability. The findings suggest that climate alone cannot explain the observed vertebrate turnover in the region, with human activity, including the introduction of cattle and changes in habitat exploitation, playing an important role.

Summary: Understanding the diets of extinct hominin species is crucial for comprehending their ecology and our own evolution. Various approaches, both historical and recent, have been employed to elucidate diet in paleontology. While tooth studies have traditionally been the gold standard, new methods like dental calculus analysis, biogeochemistry, and dental microwear analysis are providing direct evidence of the foods consumed by ancient individuals. These multi-proxy approaches, when combined with other techniques, challenge traditional interpretations of early hominin diets and reshape paleobiological understanding.
