Job satisfaction in graduates of the career of dental surgeon: a cross sectional study / Satisfação no trabalho em graduados da carreira de cirurgião-dentista: um estudo transversal

ABSTRACT This study aims to estimate job satisfaction levels in graduated of dental school of Autonomous University of Guerrero, México, and determine which factors influence such satisfaction levels. A cross-sectional study was carried out in 144 dentists graduated from the dental school of Autonomous University of Guerrero through a validated survey. Logistic regression analysis was performed to obtain OR, p-value and confidence intervals (95% CI) in the STATA13 statistical program. The overall percentage of job satisfaction was 92%, while the variables that explained the model were, the role of the dentist (Owner or employed) (OR = 2.2 , p = 0.03 95% CI 1.1-4.4), and the level of satisfaction of the knowledge acquired within their academic dental school training (OR = 19.2, p = 0.00 95%CI 3.1-118). The professional satisfaction of a dentist is of great importance, because it impacts their performance at work, and is closely related to overall satisfaction of life, since both contribute reciprocally to the happiness of a person, as well as the general welfare in the community.

RESUMO Este estudo tem como objetivo estimar os níveis de satisfação no trabalho de graduados da Faculdade de Odontologia da Universidade Autônoma de Guerrero, México, e determinar quais fatores influenciam esses níveis de satisfação. Foi realizado um estudo transversal com 144 dentistas formados pela Faculdade de Odontologia da Universidade Autônoma de Guerrero por meio de um questionário validado. Uma análise de regressão logística foi realizada para obter OR, valor de p e intervalos de confiança (IC95%) no programa estatístico STATA13. O percentual geral de satisfação no trabalho foi de 92%, enquanto as variáveis que explicaram o modelo foram a função do dentista (proprietário ou funcionário) (OR = 2,2 , p = 0,03 IC 95% 1,1-4, 4) e o nível de satisfação com o conhecimento adquirido na formação acadêmica em odontologia (OR = 19,2 , p = 0,00 IC95% 3,1-118).. A satisfação profissional do dentista é de grande importância, pois impacta no seu desempenho no trabalho, e está intimamente relacionada à satisfação geral de vida, uma vez que ambas contribuem para a felicidade da pessoa, bem como para o bem-estar geral da comunidade.

Periodontal disease distribution, risk factors, and importance of primary healthcare in the clinical parameters improvement / Distribución de la enfermedad periodontal, factores de riesgo e importancia de la atención primaria en salud en la mejora de los parámetros clínicos

The objective of this study is to show the distribution of periodontal disease, risk factors, and importance of primary healthcare, for the improvement of clinical parameters. Two phases study transversal and nonrandomized trial (before - after), with educational intervention and conservative treatment, were carried out at Dental School of the Universidad Autónoma de Guerrero México, in 161 subjects who met the inclusion criteria. Oral healthcare education was carried out as well as conservative periodontal treatment, with six months follow up. Clinical measurements were performed with a Williams probe, O'Leary plaque index, calculus index and dental mobility Miller method. Periodontal disease was found on 82 % of all participants. Multinomial logistic regression analysis showed an odds ratio of 14.3 (95 % CI: 2.5, 82.1), 13.4 (95 % CI: 1.7, 103.5), 29.2 (95 % CI: 3.2, 260.9) and 68 (95 % CI: 6.6, 711.0) plaque in gingivitis, mild, moderate and severe chronic periodontitis, respectively. The longitudinal panel data analysis showed a significant effect (p <0.001) in the mean decrease of the clinical parameters after intervention, probing depth 0.4 mm (95 % CI: -0.5, -0.3), pockets depth 1.1 mm (95 % CI: -1.3, -0.9), amount of pockets 4.5 (95 % CI: -5.2, -3.7), bleeding 5.2 (95 % CI: -5.9, -4.5) and dental mobility 0.6 degrees (95 % CI: -0.7, -0.5). Primary healthcare is still the best option to improve the periodontal health in population who do not have access to specialty services. Dentists can achieve significant clinical improvement at very low cost, if they are aware of primary health care.

El objetivo del estudio fue mostrar la distribución de la enfermedad periodontal, los factores de riesgo y la importancia de la atención primaria de salud, para la mejora de los parámetros clínicos. Material y método: Estudio de dos fases transversal y no aleatorizado (antes - después), con intervención educativa y tratamiento conservador, realizado en la Facultad de Odontología de la Universidad Autónoma de Guerrero México, en 161 sujetos que cumplieron con los criterios de inclusión. Se llevó a cabo una educación sanitaria oral, así como un tratamiento periodontal conservador, con un seguimiento de seis meses. Las mediciones clínicas se realizaron con una sonda Williams, el índice de placa O'Leary, el índice de cálculo y el método Miller de movilidad dental. Resultados: se encontró enfermedad periodontal en el 82 % de todos los participantes. El análisis de regresión logística multinomial mostró un odds ratio de 14.3 (IC 95 %: 2.5, 82.1), 13.4 (IC 95 %: 1.7, 103.5), 29.2 (IC 95 %: 3.2, 260.9) y 68 (IC 95 %: 6.6, 711.0) placa en gingivitis, periodontitis crónica leve, moderada y grave, respectivamente. El análisis de datos del panel longitudinal mostró un efecto significativo (p <0.001) en la disminución media de los parámetros clínicos después de la intervención, profundidad de sondeo 0.4 mm (IC 95 %: -0.5, -0.3), profundidad de bolsillos 1.1 mm (IC 95 %: -1.3, -0.9), cantidad de bolsillos 4.5 (IC 95 %: -5.2, -3.7), hemorragia 5.2 (IC 95 %: -5.9, -4.5) y movilidad dental 0.6 grados (IC 95 %: -0.7, - 0.5). Conclusiones: la atención primaria de salud sigue siendo la mejor opción para mejorar la salud periodontal en la población que no tiene acceso a servicios especializados. Relevancia clínica: los dentistas pueden lograr una mejora clínica significativa a un costo muy bajo, si conocen la atención primaria de salud.

Relationship between TNF-α, MMP-8, and MMP-9 levels in gingival crevicular fluid and the subgingival microbiota in periodontal disease.

Periodontitis is modulated by a complex dysbiotic microbiota, these species stimulate upward the production of pro-inflammatory cytokines such as TNF-α, which, in turn, upregulates the production of bone resorption molecules. Enzymes such as MMP-8 and 9 have been associated with the destructive disease. This study evaluated the composition of periodontal microbiota with the checkerboard hybridization technique and its correlation with TNF-α, MMP-8, and MMP-9 evaluated with ELISA, of 80 patients (45 healthy, and 35 with chronic periodontitis). The frequency of the 18 species evaluated was higher in patients with bone loss compared with control group. TNF-α in gingival crevicular fluid was significantly higher in bone loss group (p < 0.01); MMP-8 (p = 0.34) by MMP-9 (p < 0.05) in bone loss group obtained lower values than in control group. Positive correlation of TNF-α was obtained with Aggregatibacter actinomycetemcomitans (rho = 0.38; p < 0.01), Fusobacterium nucleatum (rho = 0.25; p < 0.05) and Porphyromonas gingivalis (rho = 0.26; p < 0.05); negative correlation of MMP-8 with A. actinomycetemcomitans (rho = 0.26; p < 0.01), Capnocytophaga sputigena (rho = 0.33; p < 0.01), and F. nucleatum (rho = 0.21; p < 0.05); also negative correlation of MMP-9 with F. nucleatum (rho = 0.23; p < 0.05), P. gingivalis (rho = 0.23; p < 0.05), and Tannerella forsythia (rho = 0.26; p < 0.01). TNF-α increased due to the increase in each count of A. actinomycetemcomitans (ß = 0.57; p = 0.00). The presence of A. actinomycetemcomitans (ß = 1.88; p = 0.00), Campylobacter rectus (ß = 0.78; p = 0.01), F. nucleatum (ß = 0.65; p = 0.04), and P. gingivalis (ß = 0.65; p = 0.04) significantly increases TNF-α levels. TNF-α in gingival crevicular fluid, despite the minimal amounts collected, is a good biomarker of periodontal disease; since levels of TNF-α increases with the increase of the most harmful species to the periodontium.
