Propiedades y usos del propóleo en odontología: una revisión

El propóleo es un material pegajoso de color oscuro obtenido de diversas plantas y mezclado con cera, deriva de las abejas quienes lo utilizan para proteger las colmenas. El objetivo del presente trabajo fue realizar una revisión bibliográfica acerca de las propiedades y usos del propóleo en odontología. Se realizó una búsqueda bibliográfica de reportes publicados de marzo del 2010 a marzo del 2020 en PubMed, Imbiomed, Medigraphic, SciELO y Google Scholar usando las palabras: propóleo, propiedades, usos. Se seleccionaron 39 artículos para la revisión. Las principales propiedades reportadas fueron: antimicrobiana, antiinflamatoria, inmunomodulador y cicatrizante. Los principales usos reportados abarcaron las siguientes áreas de la odontología: prevención de caries, endodoncia, periodoncia, prostodoncia y cirugía. En los últimos años, se ha puesto especial atención a las aplicaciones del propóleo ya que se ha demostrado su eficacia en distintas áreas de la odontología.

Uma pesquisa bibliográfica de relatórios publicados de março de 2010 a março de 2020 foi realizada na PubMed, Imbiomed, Medigraphic, SciELO e Google Scholar usando as palavras: própolis, propriedades, usos. Trinta e nove artigos foram selecionados para revisão. As principais propriedades relatadas foram: antimicrobiano, anti-inflamatório, imunomodulador e cicatrização de feridas. Os principais usos relatados cobriram as seguintes áreas da odontologia: prevenção de cárie, endodontia, periodontia, prótese dentária e cirurgia. Nos últimos anos, uma atenção especial tem sido dada às aplicações do própolis, pois sua eficácia tem sido demonstrada em diferentes áreas da odontologia.

Propolis is a dark-colored sticky material obtained from various plants and mixed with wax, derived from bees who use it to protect their hives. The aim of the present work was to carry out a literature review on the properties and uses of propolis in dentistry. A bibliographic search of reports published from March 2010 to March 2020 was performed in PubMed, Imbiomed, Medigraphic, SciELO and Google Scholar using the words: propolis, properties, uses. Thirty-nine articles were selected for review. The main properties reported were: antimicrobial, anti-inflammatory, immunomodulatory, and wound healing. The main reported uses covered the following areas of dentistry: caries prevention, endodontics, periodontics, prosthodontics and surgery. In recent years, special attention has been given to the applications of propolis as its efficacy has been demonstrated in different areas of dentistry.

ENAM Gene Variation in Students Exposed to Different Fluoride Concentrations.

The ENAM gene is important in the formation of tooth enamel; an alteration can affect the lengthening of the crystals, and the thickness in enamel. The objective was to determine the presence of the single nucleotide variant (SNV) rs12640848 of the ENAM gene in students exposed to different concentrations of fluoride. METHODS: A cross-sectional study was conducted on students exposed to high concentrations of fluoride in the city of Durango which were divided according to the severity of fluorosis and dental caries. Genotype determination was performed by DNA sequencing. The relationship between the severity of dental fluorosis and the allele distribution was determined by the Fisher's exact and Kruskal-Wallis tests. RESULTS: Seventy-one students were included for the sequencing. In the different allelic variations, for the normal genotype AA/TT, the control group presented 75%, for the AG/TC variation, 70.8% in the TF ≤ 4 group, 65% in TF ≥ 5, and 16.7% in TF = 0; with respect to GG/CC variation, 12.5% in TF ≤ 4, 22% in TF ≥ 5, and 8.3% in TF = 0 group (p = 0.000). CONCLUSION: The ENAM gene showed an association in the population exposed to different concentrations of fluoride.

[Dental caries experience and its relation to oral hygiene in Mexican children]. / La caries y su relación con la higiene oral en preescolares mexicanos.

INTRODUCTION: Dental caries is public health problem in Mexico and there are few studies on preschool children. OBJECTIVE: The aim of this study was to determine the caries experience in preschool children and its relation to oral hygiene in an underserved area of ​​the state of Mexico. MATERIAL AND METHODS: A cross-sectional, descriptive, observational and analytical study in children aged four and five years of age enrolled in children´s centers. The sociodemographic variables were obtained through a questionnaire. Clinical evaluation of each of the infants was performed using the CPOD index for primary teeth caries , the criteria of the World Health Organization, and the significant caries index was calculated and oral hygiene was assessed using the criteria of the O'Leary index. Calibration was kappa>0.86 for indexes. RESULTS: The study population consisted of children of both genders: 69.5% had caries experience, and the index of decayed, missing, and filled teeth (DMFT) was 3.52±3.7 (d=3.37±3.5; m=0; f=0.11±0.51). The significant caries index was 8.95±0.39 (d=8.68±0.41; f=0.26±0.13). In total, 98.2% of children with caries experience had poor oral hygiene (DMFT: 4.91: 95% CI: 3.99-5.84), whereas in children with good hygiene it was 0.17 (95% CI: -0.18-0.51); existing association between caries experience and oral hygiene RM 913 (95% CI: 864-962; p<0.01). CONCLUSIONS: The caries experience of preschool children was high and was associated with poor oral hygiene affecting their dentition and usually is associated with caries in permanent dentition associated to social deprivation. Preventive programs are recommended from the first stage of life.
