RESUMO
Objective: The aim of this study was to describe artificial intelligence, machine learning, and "Dentronics" applications and perspectives in dentistry. Materials and Methods: A literature review was carried out to identify the applications of artificial intelligence in the field of dentistry. A specialized search for information was carried out in three databases such as Scopus, PubMed, and Web of Science. Manuscripts published from January 1988 to November 2021 were analyzed. Articles were included without any restriction by language or country. Results: Scopus, PubMed, and Web of Science were found to have 215, 1023, and 98 registered manuscripts, respectively. Duplicates (191 manuscripts) were eliminated. Finally, 4 letters, 12 editorials, 5 books, 1 erratum, 54 conference papers, 3 conference reviews, and 222 reviews were excluded. Conclusions: Artificial intelligence has revolutionized prediction, diagnosis, and therapeutic management in modern dentistry. Finally, artificial intelligence is a potential complement to managing future data in this area.
RESUMO
OBJECTIVE: To perform a bibliometric analysis of the national scholarly output of all dental schools in Peru in Scopus through a retrospective study after the promulgation of the Peruvian University Law 30220 in 2014. METHODS: This was a descriptive, comparative, retrospective, and cross-sectional study. A search of the Scopus database was performed to identify scholarly output in dentistry between 2014 and 2019. A total of 287 scientific articles with affiliation with the dental faculties of Peruvian public and private universities were evaluated. The data was extracted from Scopus using a complex formula developed from the words of the thesaurus MeSh (Medline) and Emtree (base) with words related to dentistry combined with the AF-IDs of the Peruvian universities. RESULTS: The Top 10 in the scholarly output of all the Peruvian public and private dental schools were as follows: firstly, the Universidad Peruana Cayetano Heredia (UPCH), with 79 scholarly outputs publications and 5.2 citations per article, followed by the Universidad Nacional Mayor de San Marcos (UNMSM) with 53 scholarly outputs publications and 2.6 citations per article, and in third place, the Universidad Cientifica del Sur (UCSUR) with 49 scholarly outputs publications. In general, it was found that, of the 30 Faculties of Dentistry in Peru, only 10 in the public and private universities have a scholarly output greater than 5 to belong to the top 10. In addition, it was found that, according to the share of publications per journal quartile by the CiteScore Percentile of all the public and private Peruvian Faculties of Dentistry, in 2019, it presented the highest number of scientific publications in all quartiles with 20,33,14 and 43 articles in the quartiles Q1, Q2, Q3, and Q4, respectively. The highest number of scientific publications was produced in 2019 with 20, 33, 14, and 43 articles in quartiles Q1, Q2, Q3, and Q4, respectively. CONCLUSION: The UPCH, UNMSM, and UCSUR dental schools were the most productive. Both public and private universities presented an evident increase in their scientific publications in Scopus after the promulgation of the University Law 30220 in 2014.
RESUMO
The purpose of this case report was to describe a technique to modify the free gingival graft by perforations within the graft to guarantee a horizontal increase in the keratinized mucosa in the anteroinferior sector of a total edentulous mandible after osseointegration of previously placed dental implants in a hybrid prosthesis protocol. A 71-year-old male underwent free modified gingival graft surgery with perforations at the level of each implant. At 3 months, the mucosa appeared to be healthy and keratinized, especially at a horizontal level around the implants previously diagnosed with mucositis, providing the patient with satisfactory results. Finally, the hybrid prosthesis was cleaned and polished due to the presentation of a hard plate at the level of the abutments. Within the limitations of this case report, further research is needed to evaluate the long-term efficacy of this modification to the free gingival graft.
RESUMO
BACKGROUND: The new coronavirus called COVID-19 originated in the city of Wuhan, China and has currently spread to different continents, leading the World Health Organization (WHO) to declare a "pandemic". Therefore, the aim of this review was to present a new proposal for a care protocol in Peruvian Dentistry: Provisional review of the diagnosis, treatment, epidemiological characteristics, routes of transmission and recommendations of COVID-19. MATERIAL AND METHODS: A search of digital scientific literature was made in the databases: Science Direct, Pubmed and Google Scholar. The Boolean operators AND, OR and NOT: "Covid-19" "Dental" "Routes of transmission. They were included Scientific articles published in English between December 2019 - March 2020. RESULTS: Different studies were found mainly of epidemiological, observational and experimental design. On March 6, 2020, the President of the Republic of Peru confirmed and declared in Peru the beginning of the first case of coronavirus. According to reports from the Ministry of Health (MINSA) as of July 30, there are: PCR (+) 108, 299; Rapid test (+) 292, 384 positive cases and 18, 816 deceased with a lethality of 4.7%. CONCLUSIONS: Within the limitations of this literature review, the presence of the virus is inevitable in dental practice. The dentist must understand the evolution of this microorganism like all vulnerable professionals in the health sciences. Key words:COVID-19, dentistry, Peru, protocol, routes of transmission.
RESUMO
Currently, dental implants are a very frequent therapeutic alternative for replacing missing teeth. However, they are not exempt from developing complications of infectious origin. Therefore, this case report describes a 67-year-old female patient presenting infectious complications caused by suture rupture. Surgery combined with therapeutic management with antibiotics was performed, allowing preservation of the osseointegration of the implants in the lower arch. Within the limitations of this study, it was shown that more research is needed to determine the success and survival of implants presenting complications due to infections during the osseointegration process.
RESUMO
AIM: The aim of this study was to evaluate the hydrogen peroxide and cetylpyridinium chloride as bacterial decontaminants of dental unit water lines at a private Peruvian dental school. MATERIALS AND METHODS: Water samples were obtained from 66 dental units of a University Dental Clinic before decontamination treatment and at days 3 and 7 thereafter. The biofilm treatments were applied equitably among the two treatment groups (n = 22) and one negative control (distilled water). The samples obtained on each collection day were taken to the biochemical laboratory in thermal boxes and then diluted, seeded, and incubated at 37°C for 24h to count colony forming units per milliliter (CFU/mL). RESULTS: The samples to which hydrogen peroxide were applied had a mean of 1.53 × 105 CFU/mL before application, 0.04 × 105 CFU/mL at day 3, and 0.03 × 105 CFU/mL at day 7, whereas the samples undergoing cetylpyridinium chloride treatment had a mean of 1.74 × 105 CFU/mL before application, 615.38 CFU/mL on day 3, and 307.69 CFU/mL on day 7. Distilled water treatment showed a mean of 1.72 × 105 ± 0.39 × 105 CFU/mL at baseline, 1.51 × 105 ± 1.40 × 105 CFU/mL at day 3, and a mean of 1.74 × 105 ± 0.47 × 105 CFU/mL at day 7. Statistically significant differences were found among the three treatment groups at days 3 (P ≤ 0.001) and 7 (P ≤ 0.001) but not at baseline (P = 0.306). CONCLUSIONS: The antibacterial effect of cetylpyridinium chloride was significantly greater than that of hydrogen peroxide and distilled water, and can, therefore, be used for bacterial control in the water lines of dental units.
