Three-dimensional dento-skeletal effects of mandibular midline distraction and surgically assisted rapid maxillary expansion: A retrospective study.

It was the aim of the study to provide a three-dimensional evaluation of dento-skeletal effects following bone-borne vs tooth-borne mandibular midline distraction (MMD) and tooth-borne surgically assisted rapid maxillary expansion (SARME). A retrospective observational study was conducted. Cone beam computed tomography (CBCT) records were taken pre-operatively (T1), immediately post-distraction (T2) and 1 year post-operatively (T3).

Oral and craniofacial research in the Generation R study: an executive summary.

Objectives: Oral conditions are of high prevalence and chronic character within the general population. Identifying the risk factors and determinants of oral disease is important, not only to reduce the burden of oral diseases, but also to improve (equal access to) oral health care systems, and to develop effective oral health promotion programs. Longitudinal population-based (birth-)cohort studies are very suitable to study risk factors on common oral diseases and have the potential to emphasize the importance of a healthy start for oral health.

The Global Impact of COVID-19 on Craniomaxillofacial Surgeons: A Follow-Up Survey After One Year.

Study Design: Comparative cross-sectional.

Objective: To measure the impact that COrona VIrus Disease-19 (COVID-19) has had on craniomaxillofacial (CMF) surgeons after 1 year and compare it with 2020 data by () measuring access to adequate personal protective equipment (PPE), () performance of elective surgery, and () the vaccination status. This should be investigated because most CMF surgeons felt that hospitals did not provide them with adequate PPE.

Current Practice for Transverse Mandibular and Maxillary Discrepancies in the Netherlands: A Web-Based Survey Among Orthodontists and Oral and Maxillofacial Surgeons.

The main objective of this study was to provide an overview of the current practice for transverse mandibular and maxillary discrepancies in the Netherlands using a web-based survey. Orthodontists (ORTHO) and Oral and Maxillofacial Surgeons (OMFS) in the Netherlands were invited to the web-based survey via their professional association. Three cases were presented which could be treated non-surgically and surgically.

Associations Between Prenatal, Perinatal, and Early Childhood Vitamin D Status and Risk of Dental Caries at 6 Years.

Background: Previous studies have suggested that insufficient concentrations of vitamin D are associated with dental caries in primary teeth, but evidence remains inconclusive.

Objectives: We assessed the longitudinal associations between prenatal, perinatal, and early childhood serum 25-hydroxyvitamin D concentrations [25(OH)D] and the risk of dental caries in 6-year-old children.

Methods: This research was conducted within the Generation R Study, a large, multi-ethnic, prospective cohort study located in Rotterdam, the Netherlands.

The Global Impact of COVID-19 on Craniomaxillofacial Surgeons.

Study Design: The COrona VIrus Disease-19 (COVID-19) pandemic has disrupted craniomaxillofacial (CMF) surgeons practice worldwide. We implemented a cross-sectional study and enrolled a sample of CMF surgeons who completed a survey.

Objective: To measure the impact that COVID-19 has had on CMF surgeons by (1) identifying variations that may exist by geographic region and specialty and (2) measuring access to adequate personal protective equipment (PPE) and identify factors associated with limited access to adequate PPE.

Caries experience among children born after a complicated pregnancy.

Objectives: Behavioural and lifestyle factors, as oral hygiene and diet, are well-established risk factors in the pathogenesis of dental caries, though displaying large differences in susceptibility across individuals. Since enamel formation already starts in utero, pregnancy course and outcome may eventually play a role in enamel strength and caries susceptibility. Therefore, we studied the association between history of pregnancy complications and the caries experience in their six-year-old children.

Esthetics and Patient-Reported Outcomes of Implants Placed with Guided Bone Regeneration and Complete Native Bone: A Prospective Controlled Clinical Trial.

Purpose: When encountering a buccal bone defect during implant placement, guided bone regeneration (GBR) is a well-accepted method for bone reconstruction. However, it is still unclear if the esthetic and patient-reported outcomes are comparable to implants placed in native bone. The purpose of this prospective trial was to compare implants placed with a GBR procedure for a small (≤ 4 mm) buccal defect with implants placed completely in native bone (control).

Consortium-based genome-wide meta-analysis for childhood dental caries traits.

Prior studies suggest dental caries traits in children and adolescents are partially heritable, but there has been no large-scale consortium genome-wide association study (GWAS) to date. We therefore performed GWAS for caries in participants aged 2.5-18.

Foetal, neonatal and child vitamin D status and enamel hypomineralization.

Objectives: Recent literature suggested that higher vitamin D concentrations in childhood are associated with a lower prevalence of molar incisor hypomineralization (MIH). As tooth development already starts in utero, we aimed to study whether vitamin D status during foetal, postnatal and childhood periods is associated with the presence of hypomineralized second primary molars (HSPMs) and/or MIH at the age of six.

Methods: Our study was embedded in the Generation R Study, a population-based, prospective cohort from foetal life onwards in Rotterdam, the Netherlands.

The effect of resorbable membranes on one-stage ridge augmentation in anterior single-tooth replacement: A randomized, controlled clinical trial.

Aim: To evaluate the effect of resorbable membranes on one-stage ridge augmentation procedures in small (2-4 mm) buccal bony dehiscences in anterior maxillary single-tooth replacement.

Materials And Methods: Patients with a buccal bony dehiscence after implant placement in the esthetic zone were randomly allocated to one-stage ridge augmentation with (M+) or without a membrane (M-). Second-phase surgery was performed after 8 weeks, and follow-up was performed 1, 6, and ≥12 months after loading.

Social inequalities and dental caries in six-year-old children from the Netherlands.

Objectives: The purpose of our study was to investigate the association of different socioeconomic and sociodemographic factors with dental caries in six-year-old children. Furthermore, we applied a district based approach to explore the distribution of dental caries among districts of low and high socioeconomic position (SEP).

Methods: In our cross-sectional study 5189 six-year-olds were included.

Ethnic Disparities in Dental Caries among Six-Year-Old Children in the Netherlands.

The aim of this study was to investigate potential differences in caries prevalence of children from ethnic minority groups compared to native Dutch children and the influence of socio-economic status (SES) and parent-reported oral health behaviour on this association. The study had a cross-sectional design, embedded in a population-based prospective multi-ethnic cohort study. 4,306 children with information on caries experience, belonging to 7 different ethnic groups, participated in this study.

Early Caries Predicts Low Oral Health-Related Quality of Life at a Later Age.

Oral health-related quality of life (OHRQOL) is the perceived impact of one's own oral health on daily life. Oral diseases influence children's OHRQOL directly, but OHRQOL might also be related to oral health experiences from the past. We investigate the relation between dental caries at the age of 6 with OHRQOL assessed at the age of 10.
