The composition of dentin is different in primary and permanent teeth but the same bonding protocol has been advocated for both. Very few studies are available for primary teeth regarding the current bonding agents. The aim of the study was to analyse and compare the changes in the ultra...
Gemination in bilateral mandibular primary teeth is a rare anomaly. This kind of anomaly features two crowns totally or partially separated, but only one root and one root canal. At intraoral clinical examination of children we found different anatomy of mandibular primary canines with two partially...

Rhesus monkeys belong to the cercopithecids of the primates and, their tooth formura is the same as that of the humans in both milk and permanent teeth. Morphologically, their teeth are closely allied to the humans. The results were as follows : 1. The development of the cingulum in the...
more molariform lateral teeth which increase in area and width from small to large specimens, while the medial-inferior and medial-superior teeth lengthen producing a single cusp. The ontogenetic variation in dietary composition (increasing importance of cephalopods with size) appeared to be facilitated...
Additionally, the record ofRhenechinusis the youngest occurrence of an echinocystitid echinoid in the fossil record, indicating that this family ranged from the Silurian (Aeronian or Telychian) to at least the Middle Devonian (Givetian), prior to going extinct. The morphological details provided...
in the placode and in the primary enamel knot at the cap stage32,33,35. It has been demonstrated that transgenic mice overexpressing Eda or Edar show molar teeth with extra cusps and, in some cases, supernumerary teeth36,37. It has been indicated that the morphogenesis of teeth, as well...
Eight studies (14, 37, 39, 43, 44, 47, 52, 53) with a total of 1779 teeth evaluated the presence of RF (Table 2). About one fourth of multirooted teeth (24.9%) had RF, and 2-rooted premolars had a higher incidence of RF than their 3-rooted counterparts (24.3% and 0.6%, res...
