Melt densities in the CaO-FeO-Fe2O3-SiO2 system and the compositional dependence of the partial molar volume of ferric iron in silicate melts [PDF]

open access: yes, 1988
The densities of 10 melts in the CaO-FeO-Fe2O3-SiO2 system were determined in equilibrium with air, in the temperature range of 1200 to 1550°C, using the double-bob Archimedean technique.

Human deciduous mandibular molar incremental enamel development. [PDF]

open access: yes, 2010
Quantitative studies of incremental markings retained within human enamel have reconstructed the duration and rate (crown and cusp formation times, initiation and completion, daily enamel secretion rates) of permanent tooth development. This approach has

The evaluation of occlusal relationship between the primary canines and primary molars in 3 to 5-year-old Iranian children [PDF]

open access: yesJournal of Dental Materials and Techniques, 2017
Aim: As to the assessment of occlusal status pertaining to primary canines and molars, the latter is less within reach as it is difficult to guide jaws towards a centric occlusion while maintaining a vintage point in both direct and indirect observation.

Preformed metal crowns for decayed primary molar teeth [PDF]

open access: yes, 2006
Management of decay in primary molar teeth conventionally involves removal of decayed tooth and placement of a preformed metal crown (also known as a stainless steel crown) to completely cover the tooth or placement of a filling (a soft material which is

Intraspecific variation in M1 enamel development in modern humans: implications for human evolution [PDF]

open access: yes, 2008
The timing and sequence of enamel development, as well as enamel thickness, was documented for individual cusps (protoconid, hypoconid,metaconid, entoconid) in 15 unworn permanent lower first molars (M1s) from a sample of modern human juveniles.
