ABSTRACT
Teething is a physiological process that may be marked by local regional or general physiopathologies. We have studied these disorders in a sample of 499 children whom we followed from the age of 5 until the age of 30 months. The study consisted in a clinical endobuccal examination. Each month we recorded the order and the eruption date of the tooth or teeth and the disturbances that arise during the process or after, if any. We expose the results of this study in this paper. We collected local and general disturbances during the primary teeth eruption period. We considered that in certain conditions these disturbances could be to the eruption process. Teething is certainly a natural process, however considering its traumatic impact on the young child, we should not reject the aetiology in the justification of the disturbances observed in this process and seek another one which might not be valid.

Cellulitises originated from teeth are frequent in developing countries. Theyare noted as well as in child as in adult. In child, causal tooth may be primary or permanent. In a prospective trial carried at Hôpital d'Enfants Albert Royer CHU-Fann, where we studied the frequency of cellulitises among the children, the main patterns of dental affections and the causal teeth involved and, in the same way, the management and prevention of these diseases in child. We noted that: 56.52% of the cases of cellulitises recorded interest the child of pediatric dentistry age and that 87.5% of the cellulitises cases are due to a primary tooth (primary molar overall) and first permanent molar necrosis. Management and prevention of cellulitises are based on: the respect of the therapeutic protocol, dental hygiene education and systematization of setting of dental caries preventive clinical procedures like SEALANTS and stainless steel crowns as well as in primaryand permanent dentition with as main target the primary molars and the first permanent molar or 6 years age tooth.

Chronology and eruption dates of primary teeth are parameters of importance in different medical scientific fields. We carried a longitudinal clinical study to determine these parameters in a local Senegalese population. The study interests a sample of 573 Senegalese Negro children of the two sexes and its aims are to situate these parameters formally and in space in on hand, and to be able to justify; in comparison to these parameters, the disturbances which accompany often the phenomenon of dental eruption in the other hand. We have results relating to chronology and eruption date of the 20 primary teeth of each of the children. Our study strengthens data already known but it reveals also other data as well as important. Other studies are however necessary to set a good board of chronology and eruption date of primary teeth in the Senegalese population.

Apres une etude epidemiologique en milieu scolaire a Dakar; l'etat de la premiere molaire permanente a ete etudie. Une prevalence de la carie dentaire a ete trouvee (34 pour cent au maxillaire; 60 pour cent a la mandibule). 12 pour cent des premieres molaires mandibulaires doivent en etre extraites. Les consequences dentaires; parodontales et occlusales de la perte precoce des premieres molaires permanentes ont ete etudiees

Le but de la presente etude est la determination de la prevalence des malocclusions en milieu scolaire a Casablanca; au Maroc. Notre echantillon etait compose de 1073 enfants d'origine marocaine ages de 11 a 17 ans. La methode d'enregistrement des malocclusions a ete mise au point par l'OMS et la FDI. La frequence des dents permanentes absentes est elevee (20 pour cent). 22;75 pour cent des sujets examines presentent un encombrement anterieur mandibulaire. Les rapports molaires anteroposterieurs selon la classification d'angle s'etablissent comme suit: classe I; 80;47 pour cent; classe II; 6;54 pour cent; classe III; 6;95 pour cent. La plupart des auteurs admettent que les malocclusions sont en general moins frequentes chez les Africains et les Arabes que chez les Europeens

Intravenous administration of 60 mg/kg of a polysaccharide (MNR, MNZ, GLP/BO4, GLP/BO5) significantly decreases the mortality of mice exposed to a single dose of X rays. The dose reduction factors (DRF) obtained for MNZ, MNR, GLP/BO4, and GLP/BO5 given intraperitoneally 15 min before exposure were 2.16, 1.93, 1.80, and 1.94, respectively. The DRF was not increased when MNZ or GLP/BO4 were combined with injection of AET before X-ray exposure. The LD50 for the CFUs exposed in vivo in mice was 1.13 Gy for the treated mice and 0.75 Gy for the nontreated mice. This corresponds to a DRF of 1.6. The DRF calculated from the slope is 1.27.
