RESUMEN
Background@#Extrusion of debris is a major factor that results in postoperative pain during root canal treatment with various instruments and instrumentation techniques. Therefore, instrumentation techniques that extrude minimal debris into the periapical area while reducing pain are desirable. This study aimed to compare the incidence of postoperative pain and intake of analgesic medication (frequency and quantity) after endodontic treatment of mandibular posterior teeth using two single files and full-sequence continuous rotary systems with different kinematic motions. @*Methods@#Thirty-five of 105 patients were assigned equally to three groups according to the instrumentation system used: ProTaper Next (PN) X2, 25/06 (Dentsply, Maillefer, Ballaigues, Switzerland), One Shape (OS), #0.25/06 (Micro Mega, Besancon, France), and Wave One Gold (WG), Red - #0.25, 0.07 (Dentsply, Maillefer, Ballaigues, Switzerland). Five specialists were included in this study design; each professional prepared 21 teeth, and randomly selected 7 per instrument system. The VAS sheet ranging from 0 to 10 was used to record the initial and postoperative pains at 24, 48, and 72 h, and 7th day after single visit endodontic treatment in mandibular premolars and molars with a diagnosis of asymptomatic irreversible pulpitis with or without apical periodontitis. Postoperatively, an analgesic, ibuprofen 400 mg was administered for intolerable pain at a dose of 1 tablet for 6 h. The patients were asked over the telephone regarding postoperative pain at intervals of 24, 48, and 72 h, and 7 th day using a visual analogue scale.Result: There were no statistically significant differences among the PN, OS, and WG systems (P > 0.05) with regard to the incidence of postoperative pain at any of the four time points assessed. @*Conclusion@#The intensity of postoperative pain, frequency, and analgesic intake were similar across all three types of instrument systems; however, the reciprocating single file (WG) was associated with less postoperative pain than the full sequence continuous rotary file.
RESUMEN
Various dental procedures, such as injection administration, surgical treatment, and endodontic treatment, cancause injury to the nerves. The most commonly injured nerves are the inferior alveolar and lingual nerves.This can manifest as altered sensation to the area of innervation of the injured nerve, such as the lower lip,chin, teeth, tongue, and mucosa. Altered sensations or loss of sensation are relatively infrequent complicationsin daily dental practice. Here, we report an uncommon case of altered sensation in the midfacial region causedby an endodontic procedure and discuss the need to consider local dental causes in the differential diagnosisof numbness in the facial region.
RESUMEN
Introduction: Early childhood caries can affect quality of life (QoL) in children and their parents. The Oral Health related Early Childhood Quality of Life scale (OH-ECQoL) is used for measuring oral health-related QoL in North Indian preschool children. Same tool cannot be utilized only by linguistic translation in culturally different Manipuri population. Aims and Objectives: The aim of this study is to translate OH-ECQoL tool into Manipuri language and to reestablish its psychometric properties. Methods: The OH-ECQoL tool was translated into Manipuri language by forward–backward translation. The questionnaire was tested on 300 parents/primary caretakers of healthy children with the age range of 24–71 months. It was also retested on 20 parents after a gap of two weeks. Demographic characteristics and socioeconomic status were recorded in a predesigned proforma. Oral health status of children was recorded as per WHO oral health assessment form (2004). Statistical Analysis: The data were tabulated using Microsoft Excel 2010 and analyzed using SPSS version 11 software. Results: The tool possessed good internal consistency (Cronbach's alpha = 0.836) and test–retest reliability (ICC = 0.94). Parents of children who scored higher on Manipuri-OH-ECQoL questionnaire perceived their children's general and oral health as poor when compared to children with lower scores, proving acceptable concurrent validity scores. Spearman's correlation coefficient between child and family impact scores of 0.668 is supporting convergent validity, which means that dental problems affect QoL of both children and their parents. Conclusion: The translated Manipuri-OH-ECQoL tool was found to be adequately valid, reliable, and repeatable without affecting the psychometric properties of the original tool. This suggests that it can be used in studies assessing the impact of oral diseases on QoL of preschool children and their families in Manipur.
