Plaque Psoriasis (PP) and periodontitis are inflammatory disorders with a bidirectional association. They both have a qualitatively similar immune-modulatory cascade, cytokine profile, and a recently described dysbiosis. Different oral bacterial species compositions in the periodontal pocket might play a role in the development of PP. To describe the subgingival microbiota of the Mexican population with PP and the periodontal conditions. Subjects were divided into two groups: periodontal health (PH) (PH-non-PP, PH-PP) and periodontitis (PD) (P-non-PP, PD-PP). Following clinical examination, the patients were classified into three groups according to the degree of psoriasis as measured by the Psoriasis Area Severity Index (PASI) and the periodontal status according to the parameters of the American Academy of Periodontology (AAP). Subgingival microbiota samples of each patient were used to determine 40 species of periodontal bacteria by checkerboard DNA-DNA hybridization. IL-2 and IL-6 were measured by ELISA. Of the forty-eight patients with PP, 21 patients had PH and 27 patients had PD. PD-PP group has a significant increase in the percentage of plaque, gingival redness, pocket probing depth, and clinical attachment loss (P<0.001) compared to PH-PP group. Microbiologically PD-PP exhibited significantly higher mean counts for A. georgiae, A. israelii, A. naeslundii from blue complex (P<0.001) than PD-non-PP. Moreover, the counts of these Actinomyces in PD-PP increased according to the severity of index PASI. The concentration of IL-2 and IL-6 were increased in saliva from PH-PP and PD-PP patients compared to PH non- PP. PP individuals harbored a particular sub-gingival microbiota profile different from non-PP. The severity of psoriasis was related to dysbiosis of microbiota -- PASI > 5 related to periodontitis with the predominance of Actinomyces periodontal, irrespective of their periodontal condition. Finally, the severity of psoriasis could be unbalanced in subgingival microbiota and increase the risk to develop periodontitis. [ABSTRACT FROM AUTHOR]

The article presents two investigations carried out by the Faculty of Stomatology of the Benemérita Universidad Autónoma de Puebla. The first investigation focuses on the development of an alternative methodology to detect Mycoplasma pneumoniae, a microorganism related to mucocutaneous disorders. Specific oligonucleotides were designed for detection using the loop-mediated isothermal amplification (LAMP) technique, which proved to be faster and more cost-effective than conventional polymerase chain reaction (PCR). The second investigation focuses on studying the characteristics of palatal rugae during temporary dentition in the child population of the Puebla Valley. 161 palatal arches were analyzed, and the frequency distribution of the characteristics of shape, position, size, and intensity of expression of the palatal rugae was described.

It aims to determine the level of impact of the journal ORAL in the database IMBIOMED. Retrospective and longitudinal study. Consultations and visits done to the serial publications of stomatologists in the Indice Mexicano de Revistas Biomédicas Latinoamericanas (IMBIOMED) were evaluated of a group of cibermetric indicators selected with that purpose. The magazines that most people read were determined, the magazines with most articles downloaded, the total of articles, the most famous author, among others. In order to determine the most popular magazines for stomatologist, it was developed a general index from the highest position of each one of the studied publications in the classification according individual indicators.

Objective: This study was aimed at determining periodontal treatment needs, as determined by the Community Periodontal Index of Treatment Need (CPITN), in a sample of adults from the Mixteca region of the State of Puebla, in Mexico., Materials and Methods: This was a descriptive, cross-sectional, single-centre study. Previous informed consent was obtained; 60.0 % of the sample were women whose main activity was housework (46 %), 14.0 % were farmers. Average age was 37.6 ± 13.6. Gingival and Community Periodontal Index of Treatment Need proposed by the World Health Organisation and the International Dental Federation were used; they were implemented by the same, previously-standardised researcher. Means, standard deviations and confidence intervals were calculated for dimensional variables and percentages for categorical ones., Results: The gingival index gave 50.0 % light gingivitis, 32.0% moderate and 14.0 % severe gingivitis. The rear superior sextants commonly showed more 4 to 5 mm pockets, the front sextants calculus and the rear inferior sextants showed calculus and bleeding. 94.0 % of the patients required periodontal treatment (3.6 sextants per patient average)., Conclusions: Periodontal treatment needs were high in this study; nine out of ten patients in the Mixteca region of the State of Puebla required periodontal treatment. Efforts must thus be guided towards improving oral health in indigenous communities.
