title: [First permanent molar caries: a case study of Moroccan children between 6 and 15 year-old].
abstract: It is a transverse descriptive study realized from clinical files of 100 Moroccan children aged between 6 and 15 year-old having consulted the Rabat Dental Hospital (U.T.H. Ibn Sina) in Morocco between January and December 2009. The criteria of inclusion are age, Moroccan origin, first four permanent molars having made their eruption and a complete clinical file. The criteria of exclusion are the non-eruption of a first permanent molar and an incomplete clinical file. The clinical parameters are: age, sex, tooth brushing, quality of alimentation and the condition of the first permanent molars (caries, extraction, filling). The results showed that 65% of the children between 6 and 15 years have at least a first decayed permanent molar. Eight per cent of the children have at least a filling material on the first permanent molar and 4% of the children have already extracted a first permanent molar. The caries touch both sexes, both right and left sectors and both superior and lower arches without statistically significant difference (p > 0.05). The presence of the caries increased, on the other hand, with the age (p < 0.05). The relation between presence of caries, tooth brushing and quality of alimentation is not significant (p < 0.05). These results are in accordance with numerous studies and show a particular cario-sensibility of the first permanent molar.
