  • Prophylactic Extraction of Third Molars: Evidence-Based Dentistry

    • Authors: Arturo Garrocho-Rangel DDS; PhD, Amaury Pozos-Guillén DDS, PhD, Miguel Ángel Noyola-Frías DDS, Ricardo Martínez-Rider DDS, Brisa González-Rivas DDS
      Pages: 10 - 15
      Abstract: This new perspective article was performed to investigate the evidence from published dental literature about the prophylactic extraction of asymptomatic (or disease-free) impacted third molars (ITM) in adolescents and young adults. This clinical procedure is common until today and has been the origin of controversy among the dental community worldwide. However, evidence-based data from well-conducted clinical studies and systematic reviews are not sufficient to justify the routine prophylactic extraction of ITM. Active surveillance at regular intervals has been proposed as a better management strategy. As a conclusion, surgical removal of ITM is only justified in the presence of specific pathosis, independently of the patient’s age.

  • Basaloid Squamous Cell Carcinoma of the Palate: Case Report

    • Authors: Yadira V. Boza Oreamuno DDS; MSc
      Pages: 17 - 25
      Abstract: Basaloid Squamous Cell Carcinoma (BSCC) is a rare and aggressive variant of squamous cell carcinoma (SCC), with a predilection for the upper aerodigestive tract, the palate being a very rare site of development. It is constituted by a basaloid and a squamous components in variable proportions, however, the histopathological characteristics of the BSCC overlap with other neoplasias. Diagnosis with various immunohistochemical markers such as p63, Ki67, p16, and AE1 / AE3 cytokeratins have become a necessity for the specialist. The objective of this study is to present a case of BSCC in soft palate and to show the importance of the support in the immunohistochemistry for an early histopathological diagnosis. A review of the literature on this pathology is also presented.

  • Biomarkers in Gingival Crevicular Fluid: Review of Literature

    • Authors: Jorge González Quesada DDS; MSc, Sonia Rivera Álvarez DDS
      Pages: 35 - 43
      Abstract: Biomarkers are molecules that can be objectively measured and evaluated as indicators of normal biological processes, pathological processes or pharmacological responses to therapeutic intervention. In the crevicular gingival fluid, biomarkers have been studied as host proteins including enzymes, immunoglobulins, interleukins, cytokines, chemokines and prostaglandins, which could be helpful in evaluating periodontal diagnosis and treatment outcomes, as well as monitoring patients at risk of develop periodontitis. The purpose of this review is to show some of the most studied biomarkers in periodontal disease.

  • Standarization of a Protocol of Immunohistochemistry for the Detection of
           Brain Microglia in Wistar Rats

    • Authors: Karol Ramírez Chan DDS; MSc, PhD, Jaime Jaime Fornaguera-Trías PhD
      Pages: 45 - 59
      Abstract: Objective: Standardize a protocol of immunohistochemistry that has been widely used in C57BL/6J mice to identify microglia of the central nervous system in Wistar rats.  Materials and Methods: This research activity was carried out in two parts. In the first part, a protocol of immunohistochemistry was implemented to identify microglia in the central nervous system of 6 Wistar rats. A primary antibody with reactivity to rat and a specific secondary antibody to the primary were used. Once the protocol was established in rats' brains, an immunological challenge was produced with the intraperitoneal application of lipopolysaccharide in 2 Wistar rats, in order to evidence the changes in microglia morphology.  Results and Discussion: We demonstrate that without making major modifications to the original protocol, it can also be used to identify microglia in adult Wistar rats. In the near future, this immunostaining protocol will be applied to elucidate the bidirectional interaction between the brain and the immune system, under homeostatic conditions and different physiological and pathological stimuli.

  • Evaluation of a Caries Detecting Software System

    • Authors: Jay A. Aldous DDS; MS, Gary Lowder DDS, Jerald Boseman DDS
      Pages: 61 - 67
      Abstract: The diagnostic accuracy of caries detecting software that assesses density in digital radiographs was questioned. Analysis of radiographs of extracted teeth using Logicon revealed a deviation in specificity for  caries from visual examination of the  teeth as well as from their radiographic images.  Subsequent  preparation of teeth similar to  a clinical preparation for  a restoration revealed a marked deviation from the Logicon analysis.  Radiographic interpretation of early caries  and resultant treatment  decisions  are a multifaceted  complex  process that is not simplified  by desired but  unreliable  current computerized technique.

  • Spectroscopic Analysis of the Precipitate Formed by Mixing Sodium
           Hypochlorite and Chlorhexidine. In Vitro Study. Part II

    • Authors: Marianella Benavides G; DDS, Erick Hernández M, DDS, Víctor Hugo Soto Tellini, PhD
      Pages: 69 - 78
      Abstract: The aim of this study was to analyze the precipitate formed by the mixture of 5,25% sodium hypochlorite (NaOCl) and 2% chlorhexidine (CHX) through thin layer chromatography and nuclear magnetic resonance spectroscopy (RMN-¹H, 600 MHz and RMN-¹³C to 100 MHz) 1D and 2D spectra. Thus, the following groups were established: Group A corresponds to a pure freeze-dried chlorhexidine gluconate , Group B made-up by a combination of 2ml of chlorhexidine 2% and sodium hypochlorite 5.25% and Group C was a commercial sample of PCA (4-Chloroaniline 98%). The samples of group B were rinsed with distillated water and spinned during 15 minutes at 25°C, the supernatant was eliminated by vacuum and vacuum chamber for 72 hours without heating. Finally, the solid was grinded and dried in vacuum chamber for 24 hours without heating. Thin layer chromatography, shows that sample B were composed by more than one chemical substance and Chlorexidine, the RMN-¹³C showed that the signal of the amino group characteristic of PCA appears down field (δ/146.5 ppm) in C group, meanwhile in group B appears up field (δ/129ppm), which demonstrates the absence of PCA during the process. The analysis of Group B by RMN-¹³C results also, in different signals of low intensity that correspond to similar structures to chlorhexidine and potential aromatics derivatives with similar characteristics structures to chlorhexidine.

  • The Role of Socioeconomic Position in Determining Tooth Loss in Elderly
           Costa Rican: Findings from the CRELES Cohort

    • Authors: Cristina Barboza Solís DDS; MSc, PhD, Romain Fantin MSc
      Pages: 79 - 94
      Abstract: Objective: Differences in health status between socioeconomic groups continue to challenge epidemiological research. To evaluate health inequalities in tooth loss, using indicators of socioeconomic position (education level, occupation and subjective economic situation), in a large representative sample of elderly Costa Ricans, can contribute to conceive better adapted public health interventions. Methods: Data are from the Costa Rican Longevity and Healthy Aging Study (CRELES Pre-1945), a longitudinal study of a nationally representative sample of elders. 2827 participants were included in the study using data from the first wave conducted in 2005, and analyzed cross-sectionally. The sample was imputed for missing data using a multiple imputation model. Tooth loss was self-reported and informed about the quantity of missing teeth. Information on participant’s socioeconomic factors was collected via a questionnaire, including three measures approaching socioeconomic position: education level, occupation and subjective economic situation. Additional variables were included in the multivariate analyses as potential confounders. Results: Tooth loss was found to be strongly socially patterned, using variables characterizing socioeconomic position, mainly education level, occupational status and subjective economic situation. Conclusions: To highlight how socioeconomic position relates to tooth loss, can allow a better understanding of the origins of the social gradient in oral health, to tackle the most common chronic diseases across the world.
