001 of H. pylori DNA was evaluated by nested PCR using primers designed to amplify H. pylori-specific segments within the bacterial 16S rDNA. The Local trauma: An important triggering factor for gingival external primers used in first-round PCR were EHC-U and EHC-L, while recession in the second round of DNA amplification, it was used primers ET-5U and ET-5L producing a 230-bp fragment within the amplicon of the first-round BORGES FILHO, F.F.

The occurrence of this bacterium was associated with socioeconomic com.br); FINOTTI, L.; ORRICO, S.R.P. conditions, regardless of gender and ethnicities, being more frequent in low income people, and subjects aged 30 years or older, as well as individuals Smile harmony could be influenced by the smile line, gingival contour, with history of use of antimicrobial drugs. In general, H. pylori was detected lip position and correct tooth arrangement and shape. Alterations in gingival in 38.67% Indians‘ saliva and 47.5% non-Indians’ saliva, regardless of tissue, such as hyperplasia, bone crest loss compromising the gingival their periodontal health conditions. In edentulous children, H. pylori was papillae, uneven contour and exposure of root surfaces, are factors that detected in 7.5% of the samples, but its presence in oral cavity seems to affect negatively this harmony. Gingival recession (GR) is the apical be transient in these children. migration of gingival margin exposing the cementoenamel junction. It may cause unsatisfactory esthetics, dentinal hypersensitivity, root cavities, dental abrasion and other alterations. GR have a multifactorial origin, and 004 could affect a significant part of the population with good oral hygiene. The aim of this study was to evaluate the relationship between GR and local Gram-positive strict anaerobes in periodontitis: evaluation trauma due to deleterious habits and inadequate oral hygiene comparing in different Brazilian populations different research studies and case reports.

Deleterious habits like JARDIM, E.C. thumb- or pacifier-sucking, tongue interposition during swallowing, self- inflicted gingival mutilation cause gingival injury and may also be an The role of Gram-negative anaerobes in the etiology of periodontitis important factor related with GR. Therefore it may be concluded that has been evaluated but recently some Gram-positive strict anaerobes, local trauma is one of the main factors that might start and/or lead to GR such as genera Eubacterium, Mogibacterium and Slackia, are in evidence. progression. The present investigation aimed to evaluate the occurrence of these microorganisms in oral cavity of two groups of adult patients in Brazil: 100 native Brazilians and 350 non-Indian Brazilians living in urban areas of São 002 Paulo State and Maranhão State, of both genders and aged 18-96 years. The detection of Eubacterium sp., E. saphenum, S. exigua, and M. timidum Esthetic parameters in the transformation of maxillary anterior was carried out by DNA amplification by conventional PCR using specific teeth – case report primers. The comparisons of plaque index and other clinical parameters were performed by Kruskal-Wallis statistical test. Pairwise comparisons FAVARÃO, I.N. (Isabella Negro Favarão [email protected]); were performed by Bonferroni adjusted nonparametric Mann-Whitney test, KASUYA, A.V.B.; FABRE, H.S.C.; QUAGLIATTO, O.S.; FONSECA, R.B. while significant differences in the occurrence of selected microorganisms were assessed by weighted least squares method. Genii Eubacterium Several principles should be managed during restorative treatment and S. exigua were largely distributed in the population, regardless of planning and execution in order to achieve harmonic esthetic results. The the periodontal status and geographical area and ethnicity, while M. presence of deficient restorations or unaesthetic dental format contributes to timidum and E. saphenum were rarely isolated from native Brazilians. a disharmonic smile, but can be corrected by a direct bonding technique. The E. saphenum was detected from 31.58% Indians with periodontitis and aim of this study is to report the sequence of analysis of esthetic parameters 14.19% periodontally healthy natives, while its frequency was 46.86% non- and clinical steps, from treatment planning to final polishing, in order to Indians with periodontitis and 38.58% periodontally healthy non-Indians. M. achieve success in esthetic transformation of maxillary anterior teeth. A timidum and S. exigua were observed in a higher prevalence in non-Indians, 45 year-old male patient presented with a disharmonic smile according to regardless of their periodontal conditions. The presence of M. timidum the esthetic standards, with grooves and stains in the anterior teeth, ample was evidenced from 44% non-Indians with periodontitis and from 23.68% interdental cervical spaces between teeth 12 and 13, and 11 and 12, and natives with gingivitis, while for S. exigua these values were 58.63% and almost no cervical spaces between teeth 11 and 21, 21 and 22 and 22 and 44.74%, respectively. In these human groups, the data did not support a 23. The anterior teeth were not in esthetic proportion (width/height ratio). major role of these Gram-positive anaerobic rods in the development of After color selection (VITA shade guide), the maxillary anterior teeth were periodontal infection. reshaped with direct bonding technique and then adjusted according to the principles of esthetic harmony and masticatory function. The maxillary anterior teeth showed better esthetic in terms of shape, texture and color, 005 with excellent final outcomes.

The proper reestablishment of the facial projection, function influence of age, gender, periodontal and socioeconomic and esthetics must be considered together in the treatment of panfacial fractures.
