Periodontitis is a chronic disease characterized by bone loss and inflammatory changes. We studied the effect of a homeopathic agent (Mercúrios Corrosivos 6 CH) and a non-steroidal anti-inflammatory drug (nimesulide) on the alveolar bone loss progression in experimentally induced periodontitis in rats. Sixty (60) Wistar rats were separated into group 1 (homeopathy), group 2 (nimesulide) and group 3 (saline solution). Silk ligatures were placed at the gingival margin level of the lower right first molar of all rats. Alveolar bone loss was evaluated by light microscopic analysis and analyzed using software Image J. The results were submitted to the analysis of variance (ANOVA) and Tukey’s posttest (p<0.05). The analysis revealed that there was a higher bone loss in diseased sites as compared with healthy sites. A significant reduction in the alveolar bone resorption was observed in group 2 (nimesulide) as compared with group 1 (homeopathy) 7 days after the induction of periodontitis. Our data provided evidence that homeopathy does not decrease alveolar bone loss as opposed to nimesulide in experimentally induced periodontitis.

Dental caries is a transmissible infectious disease in which mutans streptococci are generally considered to be the main etiological agents. Although the transmissibility of dental caries is relatively well established in the literature, little is known whether information regarding this issue is correctly provided to the population. The present study aimed at evaluating, by means of a questionnaire, the knowledge and usual attitude of 640 parents and caretakers regarding the transmissibility of caries disease. Most interviewed adults did not know the concept of dental caries being an infectious and transmissible disease, and reported the habit of blowing and tasting food, sharing utensils and kissing the children on their mouth. 372 (58.1 percent) adults reported that their children had already been seen by a dentist, 264 (41.3 percent) answered that their children had never gone to a dentist, and 4 (0.6 percent) did not know. When the adults were asked whether their children had already had dental caries, 107 (16.7 percent) answered yes, 489 (76.4 percent) answered no, and 44 (6.9 percent) did not know. Taken together, these data reinforce the need to provide the population with some important information regarding the transmission of dental caries in order to facilitate a more comprehensive approach towards the prevention of the disease.

The treatment of a large dentine caries, which seemed to be a small pit-and-fissure carious lesion on the occlusal surface of the permanent mandibular right first molar in a 6-year-old boy, is presented. The treatment included the filling of the root canals and the sealing of the cavity with composite resin. Underlying periodontal tissue healing could be radiographically observed at the 14-month follow-up. It is possible that a better visual examination, with careful cleaning and drying of teeth, may improve occlusal caries detection. Dentists should examine bitewing radiographies carefully for occlusal demineralization. As radiographies are probably an effective method of lesions caries diagnosis, they should be recommended at appropriate ages to aid early detection of these lesions.

O tratamento de uma cárie grande do dentine, que pareça ser um lesion carious do poço-e-pit-and-fissure pequeno na superfície occlusal do primeiro molar da direita mandibular permanente em um menino de 6-year-old, é apresentado. O tratamento inclui o enchimento dos canais da raiz e do sealing da cavidade com resina composta. O tecido peridental subjacente que healing podia radiographically ser observado na continuação de 14 mês. É possível que uma examinação visual melhor, com limpeza cuidadosa e secagem dos dentes, pode melhorar a deteção occlusal da cárie. Os dentistas devem examinar radiographies do bitewing com cuidado para o demineralization occlusal. Porque as radiografias são provavelmente um método eficaz do diagnóstico da cárie dos lesions, devem ser recomendados em idades apropriadas ajudar à deteção adiantada desta lesão.

Epidermolysis bullosa (EB) consists of a group of genetic hereditary disorders in which patients frequently present fragile skin and mucosa that form blisters following minor trauma. More than 20 subtypes of EB have been recognized in the literature. Specific genetic mutations are well characterized for most the different EB subtypes and variants. The most common oral manifestations of EB are painful blisters affecting all the oral surfaces. Dental treatment for patients with EB consists of palliative therapy for its oral manifestations along with typical restorative and periodontal procedures. The aim of this article is to describe two dental clinical treatments of recessive dystrophic EB cases and their specific clinical manifestations. The psychological intervention required during the dental treatment of these patients is also presented.
