Item A study on the chronology and sequence of eruption of primary teeth in Spanish children(European journal of paediatric dentistry, 2015) Burgueño Torres, Laura; Mourelle Martínez, Rosa; Nova García, Manuel Joaquín DeAim: The aim of this study is to determine the timing of primary teeth eruption in Spanish children, and to distinguish gender and arch differences. Materials and methods: A cross-sectional study was performed on primary teeth eruption in a sample of 1,250 children (623 girls and 627 boys) from the Region of Madrid aged between 3 and 42 months. The clinical emergence of teeth was taken to estimate the mean ages of primary teeth eruption. The t test was used to analyse gender and arch differences. Results: The process of primary dentition lasted 22.28 months, and statistically significant differences were found in the eruption of homologous contralateral teeth. The first molars and maxillary lateral incisors erupted earlier in girls than in boys, with no statistically significant chronological differences. The central incisors and second molars erupted first in the mandibular arch, while the lateral incisors, canines and first molars erupted first in the maxilla. A greater chronological difference was found between the lateral incisors, which erupted more than 8 months earlier in the maxilla than in the mandible. Conclusions: In the overall sample, the first tooth to erupt was the lower right central incisor at 10.96 ± 1.88 months, and the last was the upper left second molar, at 33.24 ± 4.35 months, symmetry was found in the eruption of the deciduous teeth. The greatest chronological difference was observed in the lateral incisors, with the upper ones erupting more than 8 months before the lower ones. Although statistically significant gender differences were found, they were considered clinically irrelevant.- Project number: 169
Item Creación de espacios virtuales para favorecer el aprendizaje colaborativo en Odontopediatría con la ayuda del CV de la UCM(2016) Nova García, Joaquín de; González Aranda, Cristina; Maroto Edo, Myriam; Diéguez Pérez, Montserrat; Gallardo López, Nuria; Mourelle Martínez, Rosa; Caleya Zambrano, Antonia; Saavedra Marbán, Gloria; Alvear Campuzano, Teresa; Rodríguez Peinado, NazarethAmong all teaching methodologies focused on student learning (active methods), one of the most established in Health Sciences is Problem Based Learning (PBL), incorporated in our discipline (Pediatric Dentistry, Degree of Dentistry) under the impulse of educational innovation projects of our university (UCM). Its methodology focuses in the student's ability to solve the common problems of their clinical practice by applying knowledge and skills, so they learn to develop as a profesional. The working process is structuredin four phases and ends with a summary of the information gathered, a report with new knowledge and presentation of the problem and its resolution to the whole group. The major part of the work is done in nonschool hours, which produces a discontinous tutoring. Some drawbacks emerged from the teachers and students perspective: work overload, superficial development of the problem, lack of tutorial control and excessive autonomy, parasitism among students, collective coverup, late tasks delivery and last minute difficulties in assessing individual work.etc. After analyzing these problems, we consider the Wiki could facilitate this collaborative work. Its use could bea strategy that motivates the students to realize individual and group tasks, and could allow the visibility of the whole process. Item Influence of zoledronic acid and pamidronate on tooth eruption in children with osteogenesis imperfecta(Bone, 2024) del Río Cantero, Natalia; Mourelle Martínez, Rosa; Sagastizábal Cardelús, Belén; Nova García, Manuel Joaquín DeIntroduction: Osteogenesis imperfecta (OI) is a congenital disease comprising a heterogeneous group of inherited connective tissue disorders. The main treatment in children is bisphosphonate therapy. Previous animal studies have shown that bisphosphonates delay tooth eruption. The aim of this study is to determine whether patients with OI treated with pamidronate and/or zoledronic acid have a delayed eruption age compared to a control group of healthy children. Methods: An ambispective longitudinal cohort study evaluating the age of eruption of the first stage mixed dentition in a group of children with OI (n = 37) all treated with intravenous bisphosphonates compared with a group of healthy children (n = 89). Within the study group, the correlation (Pearson correlation test) between the type of medication administered (pamidronate and/or zoledronic acid) and the chronology of tooth eruption is established, as well as the relationship between the amount of cumulative dose received and tooth eruption. Results: The age of eruption of the study group was significantly delayed compared to the age of eruption of the control group for molars and lateral incisors (p < 0.05). Patients who received higher cumulative doses had a delayed eruption age compared to those with lower cumulative doses (p < 0.05). There is a high positive correlation between age of delayed tooth eruption and Zoledronic acid administration. Conclusion: Patients with OI have a delayed eruption of the 1st stage mixed dentition compared to a control group of healthy children. This delayed eruption is directly related to the cumulative dose of bisphosphonates and the administration of zoledronic ac.Item Influence of zoledronic acid and pamidronate on tooth eruption in children with osteogenesis imperfecta(Bone, 2024) Río Cantero, Natalia del; Mourelle Martínez, Rosa; Sagastizabal Cardelús, Belén; Nova García, Manuel Joaquín DeIntroduction Osteogenesis imperfecta (OI) is a congenital disease comprising a heterogeneous group of inherited connective tissue disorders.

Methods: An in vitromicro push-out test on 150 samples (n = 50) per group per adhesive, namely, Adhese Universal(ADH; Ivoclar Vivadent), Futurabond U (FUT; Voco GmbH) (Test), and Scotchbond Universal withpre-conditioning (SCO; 3M) (Control), to record bond strength (BS) and type of adhesive failure.Results: The results of the different adhesives (megapascals (MPa)) varied, showing no statisticalsignificance. The corresponding averages are in MPa: ADH, 13.66 2.81; FUT, 14.48 2.88; SCO,14.98 3.96. Additionally, the frequency of type of failure was as follows: mixed (60.7%), adhesive(27.3%), and cohesive (12%). Conclusions: SCO, with a pH of 2.7, showed greater resistance tofracture, while FUT, with a pH of 2.3 and no pre-conditioning, approached the same values, being aone-step adhesive. No relationship was found between failure and type of adhesive.Item Influence of 2% Chlorhexidine on the Bond Strength of Three Adhesive Systems on Primary Molars: An In Vitro Study(Applied Sciences, 2022) Velayos-Galán, Laura; Molinero-Mourelle, Pedro ; Sevilla, Pablo ; Manrique Fonseca; Mourelle Martínez, Rosa; Vera González, VicenteThe hydrolysis of the collagen matrix by metalloproteinases (MMPs) is one of the paradigms that currently arouses most interest due to its close relationship with a decrease in bond strength (BS) and consequent restoration failure. Chlorhexidine 2% has demonstrated its ability to inhibit MMPs’ activity in the permanent dentition, improving the duration of resin–dentine, but there are few studies on deciduous dentition and its possible repercussions. Aim: To determine the influence of 2% chlorhexidine digluconate (CHX) as a dentine pretreatment on the BS of three adhesive systems on primary molars. Methods: 128 primary extracted molars were assigned to eight groups at random. BS in vitro was recorded by micropush-out test, and analyzed by two-way ANOVA. Results: BS values oscillated from 15.01 MPa to 20.41 MPa. There was no statistically relevant variation between the BS total mean of those adhesive groups that had received CHX pretreatment versus those that did not. Adper Prompt L-Pop was the self-etching adhesive with the best BS. Adper Scotchbond 1XT was the total-etch adhesive with the best BS values. Conclusions: Application of 2% chlorhexidine for 60 s as dentine pretreatment did not affect the immediate BS of several adhesive systems used in primary dentition.Item Sexual dimorphism of primary dentition in Spanish children(Acta odontologica Scandinavica, 2018) Burgueño Torres, Laura; Mourelle Martínez, Rosa; Diéguez Pérez, Montserrat; Nova García, Manuel Joaquín DeAim: To analyse differences in the eruption of primary teeth between both sexes. Materials and methods: A cross-sectional study was performed in a sample of 1250 children aged between 3 and 42 months. The clinical emergence of teeth was taken to estimate average ages for primary teeth eruption. The t-test was used to analyse gender and arch differences. Results: Eruption of primary teeth began at the same time in girls as in boys; although the eruptive process was longer in girls. It was observed that almost all deciduous teeth emerged earlier in boys, except for the first molar (upper and lower) and the maxillary central incisors. The differences were statistically significant for almost all the primary teeth except for the central incisors, both upper and lower. Conclusions: By comparing the timing of the eruption of primary teeth in both sexes, it was found that eruption of almost all primary teeth took place earlier in boys than in girls and that the eruption process was shorter for boys than for girls. Most of the deciduous teeth erupted earlier in the right side in both sexes. No differences were found in the sequence of eruption of primary teeth between genders.Item Time and sequence of eruption of permanent teeth in Spanish children(European Journal of Paediatric Dentistry, 2013) Bruna del Cojo, Marta; Gallardo López, Nuria Esther; Mourelle Martínez, Rosa; Nova García, Manuel Joaquín DeAim : This was to investigate permanent teeth emergence in children and teenagers of Madrid (Spain) and to compare the data with those reported in the literature. Materials and methods Study design: cross sectional descriptive study. This study comprises data from 752 children and adolescents in Madrid (Spain). Sex, age and present permanent teeth were recorded. Results: In our study permanent teeth eruption occurred between 6.99 and 12.45 years in girls and between 7.06 and 12.81 years in boys. Overall we found no statistically significant differences in the timing of emergence between homologous contralateral teeth, however we noted that the lower arch teeth erupt before those of the upper arch and the eruption of permanent teeth occurs earlier in girls than in boys. The sequence of tooth eruption differed in both jaws but was the same in both sexes. Conclusion: Clinical examination of teeth is a simple tool to calculate tooth eruption intervals. These findings in a Spanish population are relevant for different dental setting and should be periodically reconfirmed.
