RESUMO
OBJECTIVE: To assess oral health-related quality of life (OHRQoL) changes before and after the primary surgical treatment in infants with cleft lip and/or palate (CL/P). DESIGN: Quasi-experimental study. METHODS: A total of 106 infants with CL/P younger than 2 years undergoing primary surgical treatment in the Plastic Surgery Service of the Instituto Nacional de Salud del Niño in Peru. The parent/caregiver answered a questionnaire about OHRQoL named the Peruvian version of the Early Childhood Oral Health Impact Scale (P-ECOHIS) in the pretreatment (baseline) and follow-up post-treatment. The total score of P-ECOHIS and their 2 sections (child impact and family impact) in the baseline and each follow-up period post-treatment scores were assessed. As well as, the type of the CL/P on OHRQoL, standardized effect sizes (ES) based on mean total change scores (difference between baseline and 12th month) were analyzed. RESULTS: Improvements in infant's OHRQoL after treatment were reflected in each follow-up period P-ECOHIS score compared to the baseline score. The total P-ECOHIS scores decreased significantly from 28.07 (baseline) to 7.7 (12th month; P < .0001), as did the individual domain scores (P < .0001). There were significant differences in the baseline and follow-up post-treatment scores of infants who reported improvement of the OHRQoL (P < .0001). The ES was large (3.79). The cleft lip had an improvement in the OHRQoL at 12th month post-treatment (P < .0001). CONCLUSIONS: Primary surgical post-treatment resulted in significant improvement of the infant's OHRQoL with CL/P.

PURPOSE: To estimate the taper of root canals of deciduous maxillary and mandibular canines by nano computed tomography (nano-CT). METHODS: This in vitro study involved CT scan analysis of nine maxillary and five mandibular primary canines. The images of each tooth were reconstructed using OnDemand3D software. Thereon, diameter and taper analyses were performed on the free FreeCAD 0.18 software for the three-dimensional (3D) computer-aided design model. Statistical analysis was conducted using Stata v14.0 software, adopting a significance level of 5%. RESULTS: 3D image reconstruction was performed, considering the diameters obtained along the entire length of the tooth root, and the conical model was built with a height of 10 mm. The diameters of the maxillary canine at points D0 (0 mm), D5 (5 mm), D7 (7 mm), and D10 (10 mm) were 1.62, 1.07, 0.78, and 0.49 mm, respectively, with a significant difference between the four points (p = 0.0001). Regarding maxillary canine root taper values in the cervical, middle, and apical regions, the values were 12%, 14%, and 10%, respectively. For mandibular canines, the mean diameter values obtained at points D0, D5, D7, and D10 were 1.51, 0.83, 0.64, and 0.45 mm, respectively, with significant differences among the four points (p = 0.005). The inferior canine root tapers in the cervical, middle, and apical regions were 14%, 10%, and 6%, respectively. CONCLUSION: The detailed knowledge of the root morphology of maxillary and mandibular deciduous canines, as it has been shown in vitro using nano-CT, is critical to achieve accurate and efficient endodontic treatments.
