[Factors of failure of prosthetic restoration of the acquired losses of substance of the jawbone and the mandible in sub-Saharan Africa].

The obturating prostheses of the jawbone and the prostheses of rebuilding of the mandible make it possible to restore the losses of substance of the jawbone and of the mandible and to cure the functional and Aesthetic disorders which result from these losses of substance. The success of these prosthetic restorations can be compromised by technical, economic and cultural factors. The principal factors are the importance of the losses of substance, the reduced number of teeth, the poverty of the technical plate, the persistence of certain traditional concepts.

[Therapeutic possibilities for multiple caries in children].

The exaggerated consumption of sugars under its various associate shapes to an insufficiency of mouth and tooth hygiene could drag some tooth decays. These tooth decays, when they demonstrate, leads to a destruction of the temporary teeth, with for corollaries of the aesthetic and functional problems. The therapeutic are not always apparent especially when there is coexistence of coronary destruction to juxtapose to the gum without reaching pulp with some precocious a toothlessing.

[Replacement of deciduous incisors in children: psychological aspects].

The absence of the temporary incisors could be to a genetic illness or to some multiple premature extractions. These extractions are the aftermaths of the carious lesions or some traumatisms underwent by the temporary incisors. Beyond measure the loss of the space, the premature loss some temporary incisors very often assign the relational development of the child and disturb its psychological development and the aesthetic function.

[Influence of food quality and quantity on children's teeth].

Sugar and tooth decays are bound closely. The mechanisms of destruction of the tooth from the glycolyse are known. The role played by the food in the development of the caries is unique.

[Complications of injuries to deciduous teeth].

The traumatisms of the temporary teeth are very frequent. They are bound to the acquirement of the march, to the games, to the sport and to the accidents of the public way. Favoured by the presence one improved proalveoly, they constitute a dental emergency of makes some important risks of complications.

[Treatment of protruding upper incisors using the Hawley appliance].

Early treatment of upper protrused incisors prevents these teeth from traumatism. The plate of HAWLEY, properly used, is recognised for the correction of this malocclusion.
