Calcium level in the first deciduous molar crown in relation to feeding mode during early childhood

Teeth mineralization is an essential factor in preventing dental decay as calcium is the most important mineral in the hard structure of the teeth. In the first six months after birth, calcium is provided to infant mostly via milk. The first deciduous mandibular molar crown is developed roughly during this suckling period and can be considered as one of many calcium intake indicators. This study is the first in the world of this kind to measure the calcium levels in the first deciduous molar crown in a group of 9- to 12-year-old children at the time of their natural exfoliation, living in Lebanon over the last decade, attending pediatric dentist clinics in Beirut and who were either breast- or formula-fed. Children with mixed feeding mode were eliminated from the study. Only children fed either feeding mode in the first six months of their lives were included. Calcium levels [g/kg] in molars were determined by ICP/MS following a microwave acid digestion. The mean calcium level of the first deciduous molar in our study was 358 +/- 150 g/kg. Comparing the two groups, it was 370 +/- 166 g/kg in the breastfed children and 347 +/- 136 g/kg in the formula-fed children. There was no significant statistical difference between the two modes [p = 0.580] in terms of teeth calcium content. No significant difference was found between girls and boys [p = 0.440]

[ odontogenic fibromyxoma: about a clinical case]

Myxoma is an odontogenic tumor derived from mesenchymatous components of tooth developement considered by most authors as a benign, rare and locally aggressive tumor. We report in this article the association of an upper maxillary myxoma with fibroblastic cells. An analytic description of the elements of the diagnosis is proposed in addition to the therapeutic procedure, which was adopted

[Abscess periodontal palatin vs carcinoma: clinical approach]

The periodontal abscess is a localized purulent infection that affects the tissues surrounding a periodontal pocket and causes the destruction of tooth supporting structures. Various etiologies have been proposed. The symptoms and the clinical aspect often guide the practitioner toward the diagnosis and treatment choices of this entity, particularly in its palatal location. This case report is interesting because of the uncommon associated signs and symptoms, the concomitance of other mucosal lesions, the management and therapeutic approach adopted and the follow up of the patient during the healing phase

propos d'un syndrome de gougerot-Sjogren associe a une sclerose en plaques

Gougerot-Sjogern Syndrom [GSS] is one of the more frequent auto-immune disease; yet, its etiology remains unknown. Neurological involvement is considered in around 20% of GSS cases, and in most cases, peripheral nervous system is concerned while central nervous lesions are still controversial with regard of their incidence and pathophysiology. In rare cases, multiple white matter demeylinating lesions involving brain and spinal cord have been reported as of inflammatory nature that mimic Multiple Sclerosis [MS] lesions. We report a case highly suggestive of GSS associated with a replasing remitting MS in a patient based on Poser's MS criteria

Cohorte de 23 patients Libanais porteurs d'un syndrome de Gougerot - Sjogren primitif

Gougerot-Sjogren Syndrome is a autoimmune disease in Lebanon. A retrospective study including 23 patients selected according to european criteria allowed to evaluate glandular and extra glandular mainfestations, to correlate histological, clinical and biological results, to place the histological of the minor salivary glands in the general diagnostic frame and to relate epidemiological characteristics linked to the family aspect of the syndrome
