AIM: To evaluate in vitro the antibacterial efficacy of Matricaria recutita (chamomile) essential oil at 50 and 75% against Porphyromonas gingivalis ATCC 33277 and Prevotella intermedia ATCC 25611 at 24 and 48 hours. MATERIAL AND METHODS: The sample consisted of 80 discs and Mueller-Hinton Agar, the medium chosen for the culture. To determine the bacterial sensitivity, discs were placed in each Petri dish with concentrations of essential oil at 50 and 75%, distilled water and 0.12% chlorhexidine. Subsequently, the inhibition halos were measured in millimeters at 24 and 48 hours after culture, with the Kirby-Bauer disk diffusion method. RESULTS: In groups treated with Porphyromonas gingivalis, measurements at 24 and 48 hours yielded 22.14 ± 2.61 and 22.63 ± 2.67 mm for 0.12% chlorhexidine, 18.90 ± 0.41 and 19.22 ± 0.54 mm for 75% essential oil, and 15.55 ± 0.45 and 15.77 ± 0.46 mm for 50% essential oil, respectively. No statistically significant differences were observed among the groups (p > 0.05). CONCLUSION: No significant differences were found between the antibacterial efficacy of 0.12% chlorhexidine and 50 and 75% essential oil of Matricaria recutita on Porphyromonas gingivalis and Prevotella intermedia at 24 and 48 hours. CLINICAL SIGNIFICANCE: The study demonstrates that essential oil derived from Matricaria recutita may effectively combat bacteria associated with periodontal disease. This discovery has the potential to impact dental practice by introducing a natural treatment option. Further research is warranted to fully elucidate the clinical significance and potential applications of this finding.

Antibacterial Efficacy against Streptococcus mutans of Different Desensitizing Dentifrices: A Comparison In vitro Study.

AIM: To evaluate the antibacterial efficacy of desensitizing dentifrices. MATERIAL AND METHODS: An experimental, in vitro, longitudinal, analytical, and prospective study was carried out. Subsequently, the following groups were formed: Streptococcus mutans vs Vitis® Sensible. S. mutans vs Sensodyne® Repair and Protect. Also, S. mutans vs Colgate® Sensitive Pro-ReliefTM and S. mutans vs Colgate Total 12® at 100, 50, 25, and 12.5%. Each Petri dish was properly labeled with the letter corresponding to the toothpaste and was placed in the incubator for 24 hours at 37°C. A 0.12% chlorhexidine solution was used as a positive control and distilled water as a negative control. The manuscript was written following the checklist for reporting in vitro studies (CRIS) guidelines. RESULTS: It was found that when comparing the inhibition halos of the desensitizing toothpaste against S. mutans, Colgate® Sensitive Pro-ReliefTM 100% paste had the highest efficacy at 24 and 48 hours with an average of 25.2 ± 1.0 and 23.5 ± 1.1 mm, respectively. On the other way, Sensodyne paste had no efficacy at any of its concentrations 100, 50, 25, and 12.5%. Finally, it was found that there were statistically significant differences between each of the groups evaluated with a p < 0.001. CONCLUSIONS: It was concluded that mainly the 100% pure concentrations of the desensitizing pastes had antibacterial efficacy against S. mutans. However, Sensodyne® Repair and Protect paste had no effect. CLINICAL SIGNIFICANCE: This research has clinical relevance because the use of desensitizing pastes is highly frequent. Therefore, it is necessary to know if these pastes offer an efficient antibacterial effect to control the main microorganisms of the oral cavity.

Scholarly Output in Peruvian National Dentistry according to Gender Disparity: A 10-Year Bibliometric Study.

Objective: To evaluate Peruvian scientific publications in dentistry according to sex disparity (2011-2020). Methods: This was a retrospective bibliometric study. The unit of analysis was made up of Peruvian dentistry publications indexed in the Scopus database during the last 10 years. Records with metadata (410) corresponding to the period 2011-2020 were downloaded and standardized and refined by analyzing the metadata. The search strategy was developed based on the individual profiles of each Peruvian institution that has a dental school or college. It was evaluated according to the AF-ID of each institution in the Scopus database. In addition, the information provided by the Scopus SciVal tool was used. Finally, publications, impact, and collaboration indicators were used, such as total number per document, per author, average of citations, h-index, collaboration rate, number of institutions, the Source Normalized Impact per Paper indicator, the CiteScore, and the Scopus Field-Weighted Citation Impact. Results: The greatest increase was evident in 2018, with 2019 and 2020 being the maximum peak of scientific publication growth. However, sustained growth has not been evidenced in relation to the female sex. The analysis of coauthorship by the authors revealed four large clusters, of which the first three were represented by male researchers, such as Arriola-Guillen L., Mayta-Tovalino F., and Mendoza-Azpur G., and one by a female, Guerrero María E. Evaluating the national scientific publication in dentistry according to the CiteScore, it was found that most of the publications (145) from Peru were published in Q4 journals, although 90 manuscripts were published in Q1 journals. Conclusions: The Peruvian national dental publication in the last 10 years was mainly supported by male dentists, which invites us to reflect on the need to equalize opportunities so that female researchers can also reduce these gaps.

Comparison of the Microhardness of Surface Enamel Exposed to Anti-asthmatic Inhalants.

OBJECTIVE: To determine the effect of anti-asthmatic inhalers salbutamol and budesonide on the surface microhardness of bovine tooth enamel. MATERIALS AND METHODS: The study was experimental, prospective, longitudinal, and comparative. The sample consisted of permanent mandibular incisors, which were prepared in (n = 90) blocks of dental enamel of size 3 × 3 mm and 2 mm thick, separated into 6 groups of 15 specimens each in sterile bottles properly labeled and contained in artificial saliva at 37°C. Three measurements (baseline, 5 days, and 10 days) were performed after immersion to determine the microhardness using a Vickers microdurometer programmed to apply a load of 100 gm for 15 seconds. RESULTS: It was observed that the enamel surface microhardness decreased after 5 and 10 days, after being in contact with the anti-asthmatic inhalers based on salbutamol and budesonide. In addition, it was evidenced that there is a greater decrease in the superficial microhardness of the enamel when comparing the values at the beginning and after 10 days; likewise, the reduction in the microhardness of enamel exposed to budesonide was greater (120.8 kg/mm2) compared to salbutamol (112.3 kg/mm2) (p<0.001). CONCLUSION: The two anti-asthmatic inhalers studied decreased superficial enamel microhardness, with the budesonide-based inhaler having a greater erosive effect. CLINICAL SIGNIFICANCE: This research allowed us to know the values of the microhardness of the superficial enamel after being exposed to different anti-asthmatic inhalers that are indicated in daily clinical practice. Therefore, it is important to evaluate this microhardness since the use of different inhalers is very prevalent.

Emotional Intelligence, Depression, and Risk Factors in Pregnant Peruvian Andean Adolescents: A Multivariate Logistic Regression Study.

Background: There has recently been a high increase in the prevalence of adolescent pregnancies, especially in developing countries, because they are considered vulnerable populations. The objective of this study was to determine the risk factors for low emotional intelligence and for depression in pregnant Peruvian Andean adolescents seen in a public health centre. Methods: The study was a correlational analysis of 280 pregnant Peruvian Andean adolescents using logistic regression analysis. Emotional intelligence and depression were considered dependent variables, while independent variables were age, marital status, and education. The instruments used were Beck's Depression Inventory and the BarOn Emotional Quotient Inventory: Youth version. The threshold of significance was P < 0.05. Results: Age, marital status, and level of education were not risk factors for lower emotional intelligence, because they had respective ORs of 0.8 (95% CI: 0.5-1.4), 1.6 (95% CI: 0.8-3.4), and 0.7 (95% CI: 0.0-1.1). Nor were they risk factors for depression, showing ORs of 0.8 (95% CI: 0.4-1.5), 0.6 (95% CI: 0.2-1.3), and 0.6 (95% CI: 0.3-1.1), respectively. Conclusions: Thus, the risk factors studied do not significantly influence emotional intelligence or depression in pregnant Peruvian Andean adolescents.

Histological Comparison of Post-extraction Alveolar Bone Repair Treated with Melatonin and Calcium Sulfate: An In Vivo Study in Cavia porcellus.

AIM AND OBJECTIVE: To histologically compare alveolar bone repair after tooth extraction treated with melatonin and calcium sulfate in an in vivo experimental study in guinea pigs (Cavia porcellus). MATERIALS AND METHODS: The study was of longitudinal, prospective, and experimental design in an animal bio-model. A total of 24 male guinea pigs were included, weighing from 700 to 900 g and separated into two experimental groups (melatonin and calcium sulfate) for three periods (15, 30, and 45 days) at 15-day intervals after surgery. The guinea pigs were randomly included into groups for the time evaluated. RESULTS: In relation to bone repair cells using calcium sulfate, the presence of osteoblasts at 15, 30, and 45 days was 39.0 ± 63, 55.3 ± 6.0, respectively, with 61.3 ± 10.0 cells per field. Regarding bone repair cells using melatonin, the presence of osteoblasts at 15, 30, and 45 days was 25.0 ± 3.7, 49.3 ± 1.5, respectively, with 53.6 ± 5.6 cells per field. CONCLUSION: Both melatonin and calcium sulfate were found to be useful in bone repair at a histological and clinical level, although they present certain nonsignificant, albeit marked advantages in the bone repair process when compared with the control socket at the histological level. CLINICAL SIGNIFICANCE: This research allows us to know the usefulness of these easily accessible chemicals for the generation of bone repair.

Effect of Abutment Geometry and Luting Agents on the Vertical Marginal Discrepancy of Cast Copings on Implant Abutments: An In Vitro Study.

AIM: Vertical marginal discrepancy (VMD) influences the success of implant-supported restorations. However, there is little literature that has investigated the influence of geometry and cementing agent on changes in VMD of metal copings on implant abutments. The objective was to evaluate the effect of the geometry of the abutment and cementing agents on VMD. METHODS: Cast copings were cemented on implant abutments customized cylindrical (4, 5.5, and 7 mm) and on hexagonal implant abutments (4 mm) cemented or uncemented molded copings were placed (n = 4, totally 64 samples) with different luting agents. The VMD of the copings were measured in the coping-abutment interface at three reference points using a stereomicroscope. The independent Student's t test was used for comparison between the two different abutment walls. The post hoc statistical analysis was performed by the Tukey test. RESULTS: There was a significant VMD increase between noncemented and cemented cast copings using different luting agents. Abutment geometry and luting agents significantly influenced the VMD (p ≤ 0.05). Cylindrical abutment at 7 mm in height cemented with different luting agent tested showed significantly higher VMD values than cylindrical abutments of 4 mm (p=0.019). Hexagonal abutments with a 4 mm height showed significantly higher VMD values than cylindrical 4 mm abutments using zinc oxide noneugenol and glass ionomer cements (p=0.032). CONCLUSIONS: Abutment geometry and luting agents influence the VMD of cast copings cemented on implant abutment. The higher the cylindrical abutment, the greater the VMD, and hexagonal wall abutments promote greater marginal gap.

Adhesion was measured in the area of each field magnified 10 × 10, and with an increase in magnification to 40 × 10, very dense colonies of 0.152 mm2 were observed. RESULTS: The surface energy of Vitacryl and Triplex was 40.3 ± 0.3 and 39.5 ± 0.3N/m, respectively, showing statistically significant differences (P < 0.001). On the contrary, in relation to the adhesion per cell/field of C. albicans, Vitacryl presented 15.7 ± 1.1, whereas Triplex had 16.7 ± 2.3, with no significant differences (P = 0.058). CONCLUSION: In relation to the adhesion per cell/field of C. albicans, there was no evidence of significant differences between Vitacryl and Triplex.

A Comparative Evaluation of Endodontically Treated Root Canals Obturated Using Gutta-percha with Two Different Protocols: An In-vitro Study.

OBJECTIVE: The aim of this article is to evaluate the quality of filling in endodontically treated root canals using the lateral condensation technique and modified lateral condensation technique. MATERIALS AND METHODS: Thirty-two single-rooted teeth were divided into two groups that were assigned by simple randomization according to the filling technique. Once the endodontic treatment was performed, a periapical radiograph was taken to assess the quality according to the radiographic density and tomography was taken to evaluate the quality according to the tomographic volume of spaces, compared with the post-preparation biomechanical tomography. Finally, we performed a statistical analysis (Student's t-test) to evaluate whether there were differences between the types of filling. RESULTS: Radiographic radiodensity was 182.89 ± 9.81 and 186.72 ± 6.97 HU for teeth treated with the lateral condensation technique and modified lateral condensation technique, respectively. The void volume was 3.75 ± 2.35 and 2.43 ± 1.18 mm3 for teeth treated with the lateral condensation technique and modified lateral condensation technique, respectively. CONCLUSION: No significant differences were found between the techniques for both filling quality parameters.
