Clinical decision-making regarding retention and treatment vs extraction and replacement of teeth can be a significant challenge. This systematic review and meta-analysis aimed to assess decision-making in clinical practice related to the retention and endodontic treatment of natural dentition vs extraction and replacement with implant-assisted restorations. The PubMed/MEDLINE, Scopus, Web of Science, and Education Resources Information Center (ERIC) databases were comprehensively searched for studies published through May 31, 2019. All randomized controlled trials and cohort studies that assessed the effect of endodontic treatment/retreatment and implant treatment were included. Primary outcomes included success, survival, and failure rates. Meta-analysis software was used for data analysis. Of 1550 identified articles, 5 were eligible for qualitative and quantitative analyses. All 5 of the included studies reported that both therapies are viable and predictable treatment options. The meta-analysis showed no significant difference between therapies when survival rates were considered to be successes, while a significant difference was found in favor of endodontic therapy when survival rates were considered to be failures. The available evidence suggests that both therapies have approximately similar outcomes, but endodontic therapy provides moderately better outcomes. Endodontic therapy should be considered the first option when possible.

OBJECTIVE: To identify the factors associated with the prevalence of dental pain in Mexican adolescents and young adults. MATERIAL AND METHODS: This is a cross-sectional study in which data from 638 Mexican subjects, 16-25 years of age, who were randomly selected from college applicants, were analysed. Questionnaires were administered to collect sociodemographic, economic and behavioural variables. Clinical examinations were carried out to determine the decayed, missing and filled teeth (DMFT) index. The outcome variable was dichotomised as 0 (no dental pain in the last 12 months) or 1 (dental pain in the last 12 months). Statistical analyses included binary logistic regression. RESULTS: Average age was 18.76 ± 1.76 years, and 49.2% of participants were women. Prevalence of dental pain was 34.0%. In the final model, variables significantly (P < 0.05) associated with the experience of dental pain were the use of preventive dental services (OR = 0.34), being a former smoker (OR = 2.37), self-report of very poor/poor oral health (OR = 1.94) or fair oral health (OR = 1.94), self-reported dental disease (OR = 2.06) or gingival disease (OR = 2.84). CONCLUSIONS: The prevalence of dental pain was associated with self-reported oral health status, preventive dental visits and smoking; these results have implications for dental practice. We found that recent experience of dental pain was common in young adults, being reported by one out of three subjects.

La morfología y dimensiones de ciertas estructuras anatómicas varían de población a población, así como de individuo a individuo; el canal nasopalatino (CNP) es una de estas estructuras, este se encuentra ubicado en la línea media del paladar y aloja el nervio nasopalatino y la rama terminal de la arteria nasopalatina. El propósito de este estudio es determinar la morfología y dimensiones promedio del CNP en la población mexicana mediante tomografía computarizada de haz cónico (CBCT). Se analizaron 120 CBCT de manera coronal, transversal y sagital; y se clasificaron siguiendo los parámetros de Bornstein. Para el análisis estadístico se determinó la normalidad de las variables empleando la prueba de Shapiro Wilk y la significancia estadística mediante la prueba de UMann Whitney. Los resultados mostraron diferencias estadísticas significativas en las variables analizadas del canal nasopalatino entre hombres y mujeres. De acuerdo con los datos obtenidos se puede establecer que la morfología del CNP es muy variable y se recomienda realizar un estudio morfológico y dimensional antes de cualquier intervención quirúrgica relacionada con esta zona.

Certain human structures present different dimensions and morphologies in each population and individual, the nasopalatine canal being one of these. It is located in the midline of the palate, and it contains the nasopalatine nerve and the terminal branch of the nasopalatine artery. The purpose of this study was to analyze and record measurements of the nasopalatine duct in Mexican population by Cone Beam Computed Tomography (CBCT). A total of 120 CBCT coronal, transversal and sagittal views were analyzed. The data were classified according to Bornstein´s parameters. The normality of the variables was determined with the Shapiro Wilk test and the statistical significance was determinate by U-Mann Whitney test. A statistically significant difference was found in the evaluated variables of the nasopalatal canal between men and women. The data obtained determined that the morphology of the nasopalatine canal is variable and a morphological and dimensional analysis before any surgical intervention related with the area is recommended.

OBJECTIVE: The present study aimed to identify preventive and curative dental health service utilisation (DHSU) in the context of associated clinical and non-clinical factors among adolescents and young adults in Mexico. DESIGN: Cross-sectional study. SETTING: Applicants to a public university in Mexico. PARTICIPANTS: Participants were 638 adolescents and young adults aged 16-25 randomly selected from university applicants. INTERVENTIONS: Data were collected using a self-administered questionnaire filled out by the students. For assessment of dental caries experience, we used the index of decayed, missing and filled teeth. PRIMARY OUTCOME: The dependent variable was DHSU in the previous 12 months, coded as 0=non-use, 1=use of curative services and 2=use of preventive services. RESULTS: The mean age was 18.76±1.76 years, and 49.2% were women. The prevalence of DHSU was 40.9% (95% CI 37.1 to 44.8) for curative services and 22.9% (95% CI 19.7 to 26.3) for preventive services. The variables associated with curative services were age, sex, mother's education, dental pain in the previous 12 months, caries experience, use of self-care devices and oral health knowledge. For preventive services, the variables associated were mother's education, dental pain in the previous 12 months, caries experience, use of self-care devices and self-perception of oral health. CONCLUSIONS: While differences emerged by type of service, a number of variables (sociodemographic and socioeconomic characteristics as well as dental factors) remained in the final model. Greater oral health needs and socioeconomic inequalities remained as predictors of both types of DHSU. Given the differences revealed by our study, oral health policies should refer those seeking dental care for oral diseases to preventive services, and promote the use of such services among the poorer and less educated population groups.

The aim of the present study was to examine the short-term biocompatibility of Endosequence Root Repair Material (ERRM) paste and white Mineral Trioxide Aggregate MTA by implanting them into polyethylene tubes in the subcutaneous connective tissue of rats. twenty five male Wistar rats, 3-4 months old, weighing 300-350 g, were used. The tubes were implanted dorsally into the subcutaneous connective tissues of the rats. Five animals were sacrificed at five examination time points: 1, 3, 5, 7 and 15 days. The connective tissues containing the implants were excised. These sections were studied qualitatively and quantitatively using a light microscope. An average value for each group was obtained by averaging the sum of all inflammatory cells counted in 10 randomly selected, separate areas. For the ERRM group: There was a significant increase in the number of inflammatory cells on days 1-3 and on days 5-7 (P ≤ 0.003 and P ≤ 0.024). In the WHITE MTA group, the mean values of the sum of the inflammatory cells during the periods 1-3 days and 5-7 days were statistically significant (P ≤ 0.001 and P ≤ 0.044, respectively) and the XILOPERCHA group: Difference was observed significant in the value of the sum of inflammatory cells during the period of 3-5 days (P ≤ 0.05). According to the results it can be concluded that both, ERRM as MTA, caused an inflammatory reaction, which decreased over time; suggesting that both materials are biocompatible; showing however the presence of a higher organization of collagen fibers around the implants of ERRM.

El objetivo del presente estudio fue evaluar la biocompatibilidad a corto plazo de Material de Reparación de la Raíz Endodóntica (MRRE) y el agregado de trióxido mineral (AgTM), implantándolos dentro de tubos de polietileno en el tejido conectivo subcutáneo de ratas. Se usaron 25 ratas Wistar macho, de 3-4 meses de edad, con peso de 300 a 350 g. Los tubos fueron implantados en el tejido conectivo subcutáneo del dorso de las ratas. Cinco animales fueron sacrificados en cada uno de los siguientes períodos de tiempo: 1, 3, 5, 7, y 15 días. El tejido conectivo con los implantes fue escindido y seccionado. Los cortes se evaluaron cualitativa y cuantitativamente mediante microscopio óptico. Se obtuvo un valor para cada grupo resultado al promediar la suma de las células inflamatorias contadas en 10 áreas separadas seleccionadas aleatoriamente. Para el grupo de MRRE; hubo un incremento significativo en la cantidad de células inflamatorias entre los días 1-3 y 5-7 (p ≤ 0,003 y p ≤ 0,024). En el grupo de AgTM blanco, los valores promedio de la suma de células inflamatorias entre los períodos 1-3 días, y 5-7 días mostraron ser estadísticamente significativos (p≤ 0,001 y p ≤ 0,044 respectivamente) y en el grupo control de Xilopercha se observó diferencia significativa entre los valores de la suma de células inflamatorias entre los períodos de 3-5 días (P ≤ 0,05). De acuerdo a los resultados, puede concluirse que ambos materiales, AgTM y MRRE causaron una reacción inflamatoria que disminuyó a través del tiempo, sugiriendo que ambos materiales son biocompatibles; mostrando sin embargo una mayor organización de fibras colágenas alrededor de los implantes de MRRE.

BACKGROUND: The main microorganism associated with the failure of endodontic treatments is Enterococcus faecalis. Although several endodontic therapeutics have demonstrated antimicrobial activity against E. faecalis, the antimicrobial effectiveness of chitosan (CsNPs) and silver nanoparticles (AgNPs) included into conventional endodontic sealers for endodontic therapies is still unclear. AIM: The objective of this study was to evaluate the antibacterial activity increment (AAI) of endodontic sealers containing CsNPs and AgNPs as well as some chemical components against E. faecalis by direct contact assays. METHODS: CsNPs and AgNPs were synthesized by reduction and ionic gelation methods, respectively. Nanoparticles were characterized by dynamic light scattering and energy dispersive X-ray analysis. The bactericidal activity was tested on monolayers on agar plates and collagen membrane surface assays against E. faecalis. RESULTS: The size of CsNPs was 70.6±14.8 nm and zeta potential was 52.0±5.4 mV; the size of AgNPs was 54.2±8.5 nm, and zeta potential was -48.4±6.9 mV. All materials, single or combined, showed an AAI, especially when CsNPs, chlorhexidine (Chx), and the combination of CsNPs-Chx were added. However, the combination of CsNPs-Chx showed the highest (55%) AAI, followed by Chx (35.5%) and CsNPs (11.1%), respectively. There was a significant statistical difference in all comparisons (p < 0.05). Tubliseal (40%) and AH Plus (32%) sealants showed a higher AAI on E. faecalis in the monolayer test and collagen membrane assay analyzed by scanning electron microscopy. CONCLUSIONS: Tubliseal and AH plus sealers combined with nanoparticles, especially CsNPs-Chx, could be used for conventional endodontic treatments in the control of E. faecalis bacteria.

OBJECTIVE: To determine the experience, prevalence and severity of dental caries as well as to establish the treatment needs and restorative care in adolescents and young adults. MATERIAL AND METHODS: This cross-sectional study included 638 subjects 16-25 years old candidates to enter to state public university of San Luis Potosí, México. For caries detection was used the DMFT index (sum of decayed teeth + missing teeth + filled teeth in the permanent dentition). With DMFT index data were calculated the experience, the prevalence and the severity of caries. Also are reported the significant caries index (SiC), the treatment needs index (TNI) and the care index (CI). Statistical analysis was performed using nonparametric tests. RESULTS: The mean DMFT index was 4.24 ± 3.85, prevalence 76.5% and severity of 52.3% for DMFT > 3 and 26.2% for DMFT > 6. The SiC index was 8.7. The TNI was 43.0% and 52.8% CI. No variation was observed (p > 0.05) on the experience, prevalence and severity of caries by age. The component "filled teeth" showed differences by age (p < 0.05). Women had higher caries experience and severity than men (p < 0.05), equally "decay teeth" and "filled teeth" (p < 0.05). CONCLUSIONS: We observed high levels of experience, prevalence and severity of dental caries in this sample of adolescents and young adults. We found almost 40% of untreated caries lesions. We found some differences by sex.
