Unexpectedly, a regeneration of mineral tissues beyond the MTA plug occurred which is an uncommon outcome.

Aim: The aim of this study was to determine the influence of the eating habits, dental caries and the socio-economic status on the body mass index (BMI) in children aged 1 to 16 years. Methods: It is a descriptive study conducted on 220 children who consulted the department of paediatric dentistry of Monastir from January 5th to March 6th, 2016. After measuring the height and weight of each child, an oral examination was performed. A questionnaire was filled concerning the demographic data, eating habits and oral hygiene. Results: Children belonging to the age group between 6 and 12 years represented 66.3% of the sample. Children coming from a modest socio-economic status represented 61.4%. Those coming from an urban area accounted for 76.6%. Almost all the children (94.4%) have snacks and 57.5% of them nibble. The frequency of tooth brushing was once a day for 42.9% of the children. The calculation of BMI showed that 86.9% of the children were thin. The mean DMF index was 4.14% and it was higher in children less than 6 years old and in underweight children (p 0.05). The BMI was influenced by the living environment and the frequency of sweets consumption. Conclusion: This study showed the relationship between the weight and height deficit, the high number of dental caries and the eating habits of the children. Nibbling and frequent sweets intake, which maintain a constant acid pH in the oral cavity, increase the carious risk while ensuring a feeling of satiety that results in a deficient BMI.

MOTS-CLEFS : Dent permanente immature, traumatisme, apexification, ancrage radiculaire KEYWORDS: Permanent immature tooth, trauma, apexification, radicular postLes traumatismes dentaires sont très fréquents chez les enfants et arrivent souvent à un âge où les dents permanentes sont encore immatures. La nécrose pulpaire d'une dent permanente immature provoque l'arrêt de son édification radiculaire et l'apposition de dentine sur les parois radiculaires. Cette situation rend difficile l'obtention d'une obturation canalaire conventionnelle étanche. La démarche thérapeutique dépendra du degré de l'immaturité de la dent mais aussi de l'importance du délabrement coronaire. L'objectif de cet article est de présenter la gestion de la nécrose d'une incisive permanente maxillaire immature suite à une fracture coronaire pénétrante avec délabrement important.
