Microbial Relationship of Carious Deciduous Molars and Adjacent First Permanent Molars

open access: yesMicroorganisms, 2023
(1) Epidemiological studies have shown that deciduous molar caries are related to and more severe than permanent molar caries. This study aimed to investigate whether caries subtypes in deciduous molars were associated with caries in first permanent ...

Permanent dentition occlusion in Chinese, Indian and Malay group in Malaysia

open access: yesAustralasian Orthodontic Journal, 1989
This survey outlines the proportion of the various features of occlusion in the permanent dentition of the three ethnic races, Chinese, Malay and Indian in Malaysia. The mean age of the high school children surveyed was 16.4 years. The Chinese and Malays

Early development of the human dentition revisited

open access: yesJournal of Anatomy, 2018
In this review, classical data on the early steps in human odontogenesis are summarized and updated with specific insights into the development of the upper and lower embryonic jaws to help in understanding some oral pathologies.

On a model mechanism for the spatial patterning of teeth primordia in the Alligator [PDF]

open access: yes, 1996
We propose a model mechanism for the initiation and spatial positioning of teeth primordia in the alligator,Alligator mississippiensis. Detailed embryological studies by Westergaard & Ferguson (1986, 1987, 1990) show that jaw growth plays a crucial role ...

Minimally invasive orthodontics: elastodontic therapy in a growing patient affected by Dentinogenesis Imperfecta [PDF]

open access: yes, 2017
AIM: The aim of the study was to report the use of an elastodontic therapy in a growing patient affected by Dentinogenesis Imperfecta, second class malocclusion, deep bite and lower arch crowding from the deciduous dentition to permanent one. CASE

Divergent functional traits in three sympatric Arctic charr Salvelinus alpinus morphs are not coupled with the age of the lineage divergence [PDF]

open access: yes, 2016
Three genetically discrete morphs of Arctic charr in Loch Rannoch, Scotland originated from a recent divergence within the lake (in situ) (piscivore and benthivore morphs) and from secondary contact of two older lineages (ex situ; a planktivore–piscivore/

Dynamic Alterations in Salivary Microbiota Related to Dental Caries and Age in Preschool Children With Deciduous Dentition: A 2-Year Follow-Up Study

open access: yesFrontiers in Physiology, 2018
Dynamic alterations in oral microbiota are closely related to the development of dental caries;however, changes in salivary microbiota during this process have not been extensively studied.

New early Eocene tapiromorph perissodactyls from the Ghazij Formation of Pakistan, with implications for mammalian biochronology in Asia [PDF]

open access: yes, 2012
Early Eocene mammals from Indo-Pakistan have only recently come under study. Here we describe the first tapiromorph perissodactyls from the subcontinent. Gandheralophus minor n. gen. and n. sp. and G. robustus n. sp.

A Case of Dentinogenesis Imperfecta Treated with Submerged Root Technique [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2015
Dentinogenesis imperfecta (DGI), an autosomal dominant trait, is one of the most common hereditary disorders affecting both the formation and mineralization of dentin. Either or both primary and permanent dentition is affected by it.

On a dynamic reaction-diffusion mechanism: The spatial patterning of teeth primordia in the alligator [PDF]

open access: yes, 1996
It is now well established both theoretically and, more recently, experimentally, that steady-state spatial chemical concentration patterns can be formed by a number of specific reaction–diffusion systems.
