The presence of the JP2 clone of A. actinomycetemcomitans is strongly associated with both LAgP and GAgP in young adults in Morocco. This implies that treatment of AgP in this population should include microbiological screening and aim at eradication of the bacterium when present.

-Brown tumor is one of the lesions that develop in patients with hyperparathyroidism. Skeletal bones including maxillo-facial ones can be the site of this lesion. Owing to the improve methods of blood analysis most of cases of primary hyperparathyroidism are diagnosed early and asymptomatically making advanced disease with bone lesions extremely rare. This article contains a case of a 43-year-old female patient who presented with palatal swelling as the first sign of primary hyperparathyroidism. The diagnosis was suggested by the histological findings and confirmed by the endocrinologic status.Résumé -Tumeur brune du palais comme première manifestation d'un hyperparathyroïdisme primaire. Présentation d'un cas. La tumeur brune représente une des lésions que l'on peut observer dans l'hyperparathyroïdisme. Elle touche les os, y compris ceux de la région maxillo-faciale. Le bilan biologique permet de diagnostiquer la plupart des cas d'hyperparathyroïdisme primaire à un stade précoce ; les formes évoluées asymptomatiques sont extrémement rares. Cet article présente un cas d'hyperparathyroïdisme primaire, chez une femme de 43 ans, où la première manifestation était constituée par une tuméfaction palatine. Le diagnostic a été évoqué à l'examen histologique et confirmé par le bilan endocrinien.

PurposeAggressive periodontitis, especially in its severe form, was traditionally considered to have an unfavourable prognosis. It required a complex treatment and its stabilization was often achieved by surgical therapy. The aim of this study was to investigate the results of nonsurgical periodontal treatment in severe generalized forms of aggressive periodontitis.MethodsPatients with advanced generalized aggressive periodontitis were included in the study. Probing depth (PD) of pockets ≥7 mm and clinical attachment level (CAL) of sites with attachment loss ≥5 mm were measured at baseline before nonsurgical periodontal treatment, at re-evaluation, and after treatment. The following other parameters were recorded: resolution of inflammation and bone fill. We compared the baseline values with re-evaluation and posttreatment values using the Friedman test. The Wilcoxon test with the Bonferroni correction was used for both re-evaluation and posttreatment values.ResultsSeven patients with 266 periodontal sites were examined. A significant difference was found between values, reported as medians with interquartile ranges, for PD at baseline (7.94 [7.33-8.19] mm) and both re-evaluation (4.33 [3.63-5.08] mm) and posttreatment (3.54 [3.33-4.11] mm) values (P=0.002). A significant difference was also found between values for CAL at baseline (9.02 [7.5-9.2] mm) and both re-evaluation (6.55 [6.30-6.87] mm) and posttreatment (6.45 [5.70-6.61] mm) (P=0.002). Inflammation was resolved and angular bone defects were repaired in all cases.ConclusionsThese therapeutic results suggest that this form of periodontitis could have positive outcomes after nonsurgical periodontal treatment. The reparative potential of tissue affected by severe aggressive periodontitis should encourage clinicians to save apparently hopeless teeth in cases of this form of periodontitis.Graphical Abstract
