Color regression and maintenance effect of intracoronal whitening on the quality of life: RCT—A one-year follow-up study

Objective: This randomized clinical study evaluated two parameters: 1) the clinical color rebound of whitening patients’ tooth discoloration using thewalking bleaching technique and 2) the impact on psychological and aesthetic self-perception at the one-year follow-up of patientswho underwent bleaching of nonvital teeth. Methods and Materials: Fifty study participants with nonvital tooth discoloration were recruited. Teeth were assigned randomly into one of two groups: 1) 35% hydrogen peroxide (n=25) and 2) 37% carbamide peroxide (n=25). Intracoronal bleaching was carried out over the course of four sessions using the walking bleach technique. Tooth color was evaluated after each session in order to measure the total color variation (DE). The guide was arranged from highest (B1) to lowest values (C4) for evaluating color, and color changes using Vita Classical Shade (DSGUs) units were calculated. Subjective and objective assessments were compared with the counterpart of the tooth. Aesthetic perception and psychosocial factors were evaluated before and after treatment by the Oral Health Impact Profile (OHIP) and Psychological Impact of Dental Impact Questionnaire (PIDAQ) surveys. Results: Color changes (DE) were 15.48 6 5.17 and 14.02 6 4.85 for carbamide and hydrogen peroxide groups, respectively. There were no significant differences (p.0.05) between these two groups at the one-year follow-up. There was a decrease in the PIDAQ scores after treatment compared to baseline values (p,0.05). The majority of OHIP values regressed to baseline values. Conclusion: The technique of walking bleaching was highly effective and showed minimal color rebound in nonvital teeth and had a positive effect on patients’ psychological impact at the one-year follow-up

HELLP syndrome in relation to various clinical factors in a hospital in the State of Hidalgo

Objective. To determine the prevalence of HELLP syndrome in relation to several clinical factors in the State of Hidalgo. Material and methods. This is a study of cases. The population of study, is composed of women who during their pregnancy have suffered HELLP syndrome after having suffered preeclampsia in a Hospital of Pachuca. Results. Within the complications, all patients had hyperreflexia and thrombocytopenia. 3 of them suffered headache. There was no previous preeclampsia, no nausea, jaundice, hematuria, or eclampsia. Half of the patients with HELLP presented not very high arterial hypertension, even asymptomatic, and 2 of them showed edema. There was epigastralgia, cholecystitis and liver failure in only one patient of 4. Out of a total of 8436 outpatients in the Pachuca Obstetrical Hospital, 4 patients had HELLP syndrome, with an incidence of 0.04%. Of the total of 4 patients 2 presented severe preeclampsia. Conclusion. So far, no cases have been reported in the cases treated with this syndrome in the institution where the study was carried out

Determinar la prevalencia del Síndrome de HELLP en relación a diversos factores clínicos en el Estado de Hidalgo. Material y métodos. Se realizó un estudio de casos. La población objeto de estudio, se compone de mujeres que durante su embarazo han padecido Síndrome de HELLP tras haber sufrido preeclampsia en un Hospital de Pachuca. Resultados. Dentro de las complicaciones, todas las pacientes presentaron hiperreflexia y plaquetopenia. 3 de ellas sufrieron cefalea. En ninguna hubo preeclampsias previas, tampoco náuseas, ictericia, hematuria o eclampsia. La mitad de las pacientes con HELLP presentaron hipertensión arterial no muy alta, incluso asintomáticas, y de igual manera 2 de ellas mostraban edema. Hubo epigastralgia, colecistitis y falla hepática solo en una paciente de un total de 8436 egresos que hubo en el Hospital obstétrico de Pachuca, 4 pacientes presentaron Síndrome de HELLP, arrojando una incidencia de 0.04%. Del total de 4 pacientes 2 presentaron preeclampsia severa. Conclusión.
