“…Age-related lip thinning and dental wear is well recognised. 4,8,16,17,[30][31][32] Similar to Schmidlin et al's study, 17 this study observed a similar decrease in lip heights for both black and white individuals. Thus, even though both groups experienced lip thinning with age, black individuals maintained considerably thicker lip heights compared to white individuals.…”

Lip height estimation in a southern African sample

INTRODUCTION: The South African Police Service frequently relies on craniofacial approximation and superimposition to assist in identifying unknown deceased individuals. Standards to estimate lip height are however limited. Findings from this study share medical applications. Aims and objectives: Establish reliable standards for estimating lip height using dentoskeletal measurements. METHODS: Cone-beam CTs comprising 124 black and 39 white southern African adults were assessed. A series of dimensions were recorded using a DICOM viewer with an inbuilt measuring tool. Relationships between hard tissue structures (maxillary, mandibular and total central incisor heights, their corresponding root lengths, face height (N-Gn), and nose height (N-Sn)) and respective overlaying soft tissues (upper, lower and total lip heights) were evaluated. RESULTS AND CONCLUSIONS: Statistically significant differences were observed between population, sex and age groups. A selection of regression equations to estimate lip height was calculated that included population, sex and approximate age (20-39 and 40+ years) for improved goodness-of-fit (r2-value). Regression models using face height produced the strongest multiple correlation (r-value) and goodness-of-fit (r2-value). Validation testing indicated that regression models often improved upon mean measurements, while offering a degree of individuality that mean values do not.

“…8,30,31 The observed dental wear is attributed to three factors: attrition, abrasion and erosion. 30,32 Attrition is caused by mastication or grinding between opposing teeth. The effect of attrition can be exacerbated in those who eat a particularly fibrous diet, or habitually clench and grind their teeth.…”

Tribology and Dentistry: A Commentary

2019

View full text Add to dashboard Cite

Since 1966 the term "tribology" has integrated different topics like friction, lubrication and wear. After a few years, interest in this type of phenomena rapidly spread out around the world of biology and medicine, determining a new research area defined as biotribology. This commentary is conceived within this framework with the aim of underlining the close link between tribology and dentistry regarding both physiological and restorative issues. The contact between teeth requires investigation into their tribological behavior focusing on the enamel wear process against natural teeth and/or artificial teeth, allowing us to obtain useful information on the tribological behavior of restorative materials. Thus, tested materials may be natural teeth, restorative materials (metal alloys, ceramics, composites) or both. This work aims to make a contribution to underlining the need for greater standardization of tribological experimental procedures as well as to obtaining more homogeneous and indicative results on the tested tribo systems.

“…The mechanisms and causes of wear in dental enamel can reconstruct hominin diets (Lucas PW, Omar R et al 2013). Analysis of radiographs of fossil dentitions provides insights into the state of dental occlusion at death and possible dietary regimen practised (Sperber 2017). Dental caries can be used as a "foodprint" to identify dietary intakes of cariogenic foodstuffs.…”
