Buccal Surface of Tooth: Insights from Recent Research
Buccal Tooth Movement and Bone Formation
Buccal Translation of Teeth
Recent studies have explored the possibility of translating posterior teeth buccally and the subsequent bone formation on the buccal surface. One study involving maxillary first premolars demonstrated that buccal bodily tooth movement is achievable with minimal tipping. The research showed that buccal bone apposition can occur, although there are potential limitations, such as variations in bone height changes among patients.
Buccal Surface Wear and Dietary Indicators
Buccal Surface Wear in Historical Populations
The buccal surface wear of teeth has been analyzed to understand dietary habits and social differentiation in historical populations. For instance, a study on 19th-century Eskimo, NW Asiatic Indian, and Aborigine populations found that buccal surface microstriations are indicative of normal masticatory development and dietary habits. This suggests that buccal surface analysis can be a valuable tool for estimating dietary types in prehistoric populations.
Tooth Wear in Modern Populations
In contemporary settings, the prevalence of tooth wear on buccal surfaces has been assessed among young European adults. Significant risk factors for buccal tooth wear include dietary habits such as fresh fruit and juice intake, as well as medical conditions like acid reflux and repeated vomiting. The study found that 29% of the sample exhibited signs of tooth wear, highlighting its commonality.
Structural Changes and Dental Treatments
Effects of Tooth Bleaching
Tooth bleaching using low-temperature plasma combined with carbamide peroxide has been shown to affect the buccal surface. This method resulted in reduced surface roughness and less adhesion of Streptococcus mutans compared to traditional bleaching methods. The study concluded that plasma-assisted bleaching is less destructive to the tooth surface.
Buccal Bone Thickness
A systematic review and meta-analysis on buccal bone thickness (BBT) in the anterior maxilla revealed that BBT varies by tooth type, age, and gender. Generally, buccal bone tends to be thicker from a coronal to apical position along the root surface and from anterior to posterior in the dental arch. This information is crucial for dental procedures involving the buccal aspect of teeth.
Microwear Analysis for Dietary Reconstruction
Buccal Microwear in Fossil and Extant Primates
Buccal tooth microwear analysis has been used to infer dietary habits in both modern and fossil primates. Studies have shown significant differences in striation density and length among various primate species, suggesting that buccal microwear can effectively identify dietary differences. For example, the microwear pattern of the Miocene fossil Dryopithecus indicates a diet of abrasive, tough plant foods.
Combined Occlusal and Buccal Microwear Analysis
Combining occlusal and buccal microwear texture analysis can refine dietary reconstructions. Research on Late Neolithic-Chalcolithic populations demonstrated that using both surfaces provides complementary data, enhancing the understanding of dietary regimes. This dual-surface approach increases the number of analyzable samples and offers a more comprehensive view of dietary habits.
Conclusion
The buccal surface of teeth provides valuable insights into various aspects of dental health, dietary habits, and historical lifestyles. From understanding bone formation due to buccal tooth movement to analyzing wear patterns for dietary reconstruction, recent research highlights the multifaceted importance of the buccal surface in both clinical and anthropological contexts.
