  • Preventive Analgesia: An Evidence-Based Alternative for Dentistry

    • Authors: Daniel Chavarría-Bolaños DDS; MSc, PhD, Vicente Esparza-Villalpando DDS, MSc
      Pages: 10 - 14
      Abstract: The effective management of pain in dentistry increases the patient satisfaction, improves the treatment outcome and reduces the cost of care. To achieve this goal, different strategies are available for the administration of analgesics, such as preventive analgesia. The aim of this approach is to minimize sensitization induced by noxious perioperatory stimuli (both pre, intra and postoperatory). Available research support the favorable effect of preventive analgesia, although it also recognizes an important lack of high quality evidence to confirm its advantages. This new perspective article summarizes the preventive analgesia protocol, and its potential use in dentistry.

  • Effect of Different Silane Treatments on Long-Term Bonding Between
           Non-Etched Glass-Ceramic and Resin Cement

    • Authors: Fabián Murillo Gómez DDS; MSc, Mario F. De Goes DDS, MSc, PhD
      Pages: 31 - 44
      Abstract: The present study evaluated the bond strength between glass-ceramic and resin cement, using different silane treatments, performing no previous hydrofluoric acid (HF) etching on ceramic surface, after short- and long- term storage. One hundred and eighty glass-ceramic plaques (IPS e.max CAD®) were polished and divided into six groups (n=30) to receive different silane treatments: (1) RCP-RelyX Ceramic Primer® (one-bottle silane), (2) RCP+SB-RelyX Ceramic Primer and Adper Singlebond2® (silane plus separated adhesive), (3) SBU-Scotchbond Universal® (silane-containing universal adhesive), (4) CP-Clearfil Ceramic Primer® (silane/MDP primer), (5) NC-no-silane (negative control) and (6) PC-Previous HF etching (5%, 20s) plus RelyX Ceramic Primer® (positive control). Two resin cement cylinders (Rely X Ultimate®) were built on each plaque. Each group was divided into two sub-groups to be stored for 24 hours (24h) or 6 months (6mo) in distilled water at 37°C (n=15). Then microshear (µSBS) testing was performed. Failure mode was analyzed using scanning electron microscopy (SEM). Data were statistically analyzed by two-way ANOVA and Tukey´s test (α=0.05). Both factors and their interaction resulted statistically significant (p≤0.05). PC obtained the highest µSBS values (in MPa) at both storage times (24h: 28.11±2.44; 6mo: 19.10±3.85). After 24h storage, groups RCP+SB (10.86±3.62), SBU (8.37±4.33) and CP (8.05±3.62) were not statistically different from NC (8.00±2.51); only RCP (19.73±4.63) and PC obtained higher values. After 6 months, only PC showed higher values than NC (0.04±0.01). Cohesive failure in resin cement was more prevalent for RCP-24h and PC, while adhesive failure was more frequent among all other groups.  Clinical relevance: None of the commercially available silane primers tested, improve long- term ceramic/cement bonding without performing HF etching on ceramic surface. Combination of HF acid and silane, remain as a gold standard treatment for glass-ceramic materials.

  • Association Between the FCYRIIIA-158V-F Polymorphism and Periodontitis

    • Authors: Jorge González Quesada DDS; MSc, Rodrigo Vidal Soto Phd, Patricio Fuentes Zuleta DDS, MSc
      Pages: 49 - 58
      Abstract: The multifactorial etiology of periodontitis is recognized, where genetic and environmental factors interact to produce the disease and modify its clinical expression The aim of this study is to determine the association between the presence of the polymorphism for IgG subclass III A receptor (FCYRIIIA-158V-F) and severe periodontitis. Materials and Methods: The study sample was composed of 150 patients: 32 patients with aggressive periodontitis, 71 patients with chronic periodontitis, and 47 clinically healthy volunteers without periodontitis. Peripheral blood samples, approximately 20μl, were obtained. DNA extraction was carried out from the FTAelute micro-cards. The selected polymorphisms were amplified by PCR. Results: The genotypic frequencies of the three groups evaluated met the Hardy-Weinberg equilibrium (Chi-square test, p-value> 0.05, 95% CI). The difference between the periodontitis (chronic and aggressive peridontitis) group and the group of healthy individuals was statistically significant for the presence of the T allele (p≤0.004), with an OR of 4.03 (95% CI), the sensitivity to 93% and specificity to 23%, with a positive predictive value of 72% and a negative predictive value of 61%. Conclusions: A statistically significant association was found between the presence of the T allele in the polymorphism of FCYRIIIA-158V-F and the diseased condition (periodontitis group), suggesting that the T allele possesses a higher probability of developing severe periodontitis. Due to the importance of identifying subjects susceptible to periodontitis we recommend further studies.

  • Resistance to Dislodgement of REBILDA® Post System to Intraradicular
           Dentin

    • Authors: Daphne Ross DDS, Carlos E. Filloy Esna DDS, Juan Carlos Ramírez-Barrantes DDS; MSD, PhD
      Pages: 55 - 67
      Abstract: Currently there is controversy in the literature about clinical and adhesive effectiveness with respect to adhesive systems aimed to  root reinforcement. Thus, the objective of this study was to evaluate the Push-Out bond strength between the Rebilda® post system and the intraradicular dentine. Thus, 28 unirradicular teeth were used, cut and standardized in 16 mm. The root segments were submitted to endodontic treatment; and then randomly divided into two groups, Group 1 (n = 14): Rebilda® DC + Futurabond DC; Group 2 (n = 14): RelyX ARC + Adper Scothbond Multipurpose Plus. Ten specimens from each group were submitted  to the Push-Out Test. The remaining 4 specimens from each group were prepared for Scanning Electron Microscopy (SEM) in order to evaluate the formation of resinous extensions at the post-cement-dentin interface. Group 2 showed better results when compared to Group 1 regarding bond strength and in formation of resinous extensions or tags, but there was no statistically significant difference (p>0.05). It was concluded that the REBILDA® Post System promotes adequate bond strength to intraradicular dentin.

  • Effect of Surface Treatment on the Bond Strength of Quartz
           Fiber-Reinforced Resin Posts to Resin Cements: In Vitro Study

    • Authors: Luis A. Herrera-Ocampo DDS; MSD, Mauricio Montero-Aguilar DDS, MSc, Erika Alfaro-Mayorga DDS, MSD
      Pages: 77 - 86
      Abstract: The purpose of this study was to determine the effect of different surface treatments on the bond strength between resin cements and quartz fiber-reinforced resin posts. Materials and methods: Sixty quartz fiber-reinforced resin posts (DT Light-Post™, Bisco™) were randomly divided into 12 experimental groups (n=5), according to the resin cement used (Biscem™ or Duolink™) and the surface treatment: Alcohol (control group), silanized, primer, sandblasted, sandblasted + silanized or sandblasted + primer. Cylindrical resin specimens were obtained using nanohybrid resin. The posts were cemented to the resin discs and push-out tests were conducted. Data were analyzed with ANOVA and T test for averages comparison and the Tukey HSD test with a 95% level of significance. Results: Biscem™ cement generally showed higher bond strength when compared to Duolink™ Significant differences were found between the control group and the sandblasted + silane and sandblasted + primer groups when using Duolink™cement. With Biscem™ cement, no differences between groups or with the control group were found.. Conclusion: Surface treatments on quartz fiber-reinforced resin poles seem to have no significant effect on the bond strength to resin cements, except when using Duolink™ cement with sandblasted posts and using silane or primer.

  • Quantification of Chemokine CCL5 in Patients with Diabetes Mellitus Type 2
           and/or Chronic Periodontitis: Preliminary Study

    • Authors: Luis Sansores-España DDS, Arelly Carrillo-Avila DDS; MINE, Eduardo Sauri-Esquivel DDS, MO, Eugenia Guzmán-Marín MD, MSc, PhD, Marcela Hernández DDS, MSc, PhD, Amaury Pozos-Guillén DDS, MSc, PhD, Víctor Martínez-Aguilar DDS, MIS
      Pages: 93 - 100
      Abstract: The purpose of the present study was to quantify the presence of chemokine CCL5 (RANTES) in gingival crevicular fluid (LCG) in patients with chronic periodontitis (PC) and / or type 2 diabetes mellitus (DM2). A comparative cross-sectional study was conducted in 40 patients. LCG was taken from periodontal pockets and gingival grooves from 4 patient groups (10 per study group); patients who received periodontal, antibiotic and anti-inflammatory treatment 6 months prior to the study or who had systemic disease other than DM2 were excluded. Concentrations of CCL5 were determined by LUMINEX® assays. Descriptive statistics, one-way ANOVA, Student's T, and Pearson's correlation were performed. The quantification of CCL5 was higher in the patients who presented both diseases, followed by the group with only PC, healthy and the group with only DM2. No significant difference was found between groups and there was no correlation between quantifications and glycemic indicators. Although the differences were not significant, the group of patients with both diseases had the highest CCL5 quantification. The expression of CCL5 in LGC should be considered as a potential inducer of periodontal destruction, its determination could be useful for monitoring the health/disease of periodontal tissues.
