Tooth development is a highly heritable process which relates to other growth and developmental processes, interacts with the of entire craniofacial complex. Abnormalities tooth are common, agenesis being most common anomaly in humans. We performed genome-wide association study time first eruption number teeth at one year 4,564 individuals from 1966 Northern Finland Birth Cohort (NFBC1966) 1,518 Avon Longitudinal Study Parents Children (ALSPAC). identified 5 loci P<5×10−8, suggestive...
Objective The aim of the study was to examine prevalence malocclusion traits and extent orthodontic treatment in a Finnish adult population. Materials methods population comprised subjects (n = 1964) from Northern Finland Birth Cohort 1966 living city Oulu within 100 km it. A clinical oral dental examination with registration occlusion carried out 2012 connection 46-year follow-up survey. Data on previous were collected based questionnaire. Results In examination, 39.5% had at least one...
To assess the incidence and severity of root resorption maxillary incisors caused by ectopically normally erupting canines to analyse factors influencing using cone beam computed tomography.The study sample comprised 59 patients with a total 80 canines. Forty-six canines, in 37 patients, were defined as ectopic 34 22 normal. The resorptions analysed according studies Ericson Kurol. Multiple logistics regression was used evaluate association between various resorptions.The prevalence...
The aims of this study were to evaluate the correlation between results objective structured clinical examination (OSCE) and assessment test reliability OSCE stations.All 4th year undergraduate dental students (n = 47, 100%) attended in April 2010. divided into two groups (morning group, group 1; afternoon 2). Groups 1 2 also subgroups that stations concurrent sessions (A B). included 12 10-min stations. Clinical was based on long-term observation during semesters. disciplines assessed...
Objective: This study aimed to investigate the radiological features of permanent canines and treatment carried out ensure their eruption relative certain involved in Dental Anomaly Patterns (DAP). Material Methods: The cross-sectional part this retrospective register-based focused on 1,315 dental panoramic tomographs (DPTs) children aged 8.5–10.5 years, while longitudinal information provided for 1,269 after DPTs into oral cavity. Results: DAP more often showed evidence early (p = 0.014),...
Abstract Background The reported prevalence of infraocclusion varies widely, reflecting differences in definitions and measurement/scoring approaches. This study aimed to quantify the extent singletons twins during late mixed dentition stage dental development using a new diagnostic imaging method objective criteria. also determine any associations between gender, arch type, side tooth type. Methods Two samples were analysed, 1454 panoramic radiographs 270 models twins. Both ranged age from...
Studies on individuals with sex chromosome anomalies have demonstrated the promoting effect of Y tooth crown enamel and dentin growth. The present research investigated permanent root lengths in 47,XYY males. measurements were made from panoramic radiographs. results indicate longer roots males compared those control females. dental growth thus continues form after completion results, together sizes males, suggest that excesses are evident final, beginning a few months birth continuing up to...
Studies on individuals with sex chromosome anomalies have provided proof of a direct differential promoting effect the X and Y genes tooth crown growth. 45,X/46,XX females are one subgroup Turner patients who both normal XX cell lines. Their permanent size is reduced, which mainly due to thin enamel. 45,X likewise show reduced enamel thickness, their root reduced. By contrast, lengths roots in 47,XYY males or an extra 46,XY male constitution increased. The aim present study was investigate...
ABSTRACT Objectives To compare the impact of primary canine and first molar extractions with only regarding correction palatally displaced canines (PDCs). Materials Methods Thirty-two children aged 9.5–13.5 years 48 PDCs were randomly allocated to either double-extraction group (DEG) or single-extraction (SEG). Clinical radiographic examinations performed at baseline 6-month intervals until emerged orthodontic treatment was started. Outcome measures were: emergence maxillary (yes/no), into a...
To investigate the role of occlusion in temporomandibular disorders (TMDs) Northern Finland Birth Cohort 1966 (NFBC 1966).Subjects (n = 1962) participated clinical medical and dental examinations. The association between TMD signs diagnoses with occlusal disturbances, i.e. malocclusions interferences, was examined. Pearson's chi-square test, as expressed by odds ratios (OR) 95% confidence intervals (CI) logistic regression models, were used analysis.A statistically significant found myalgia...
To test the null hypothesis that early headgear (HG) treatment has no effect on eruption pattern of maxillary canines in mixed dentition.Sixty-eight children (40 boys and 28 girls) with a Class II tendency occlusion moderate crowding dental arches were randomized into two groups. HG was initiated immediately first group. In second group only minor interceptive procedures performed during follow-up period 2 years. Orthopantomograms taken at baseline, three times 1-year intervals, after growth...
To explore the association of facial sagittal and vertical dimensions with aesthetic assessment by three panel groups.The study population comprised adult individuals from Northern Finland Birth Cohort 1966 (NFBC1966). A clinical oral examination including digital photographs was performed. The divided into subjects lowest highest values in soft tissue measurements lower anterior height percentage (LAFH%) (60 subjects) antero-posterior jaw relationship [soft A-point, nasion, B-point (ANB)...
Previous results regarding human sex chromosome aneuploidies have shown that the X and Y chromosomes affect tooth size morphology. This study looked for effect of deficiency on permanent crown heights.The material, from Finnish KVANTTI Research Project, consisted 97 45,X females 15 45,X/46,XX females. The controls were 32 sisters 28 mothers females, eight two 35 female population controls. Crown heights all available teeth except third molars both sides jaws measured panoramic radiographs...
Objective: The aim was to study the association between stress level and chronic facial pain, while controlling for effect of depression on this association, during a three-year follow-up in general population-based birth cohort. Methods: In Northern Finland 1966 Birth Cohort, information about level, pain were collected using questionnaires at age 31 years. Stress measured Work Ability Index. Depression assessed 13-item subscale Hopkins Symptom Checklist-25. Three years later, subsample 52...
Objective. Previous studies have demonstrated differential effects of the X and Y chromosomes on dental development. The expression sexual dimorphism in terms tooth size, shape, number developmental timing has been explained especially by chromosome influence. promotes enamel, crown root dentin an effect enamel deposition. aim this research is to study influence extra development permanent length. Material methods. subjects (all whom were from Kvantti Dental Research Project) seven 47,XXX...
Single-level principal component analysis (PCA) and multi-level PCA (mPCA) methods are applied here to a set of (2D frontal) facial images from group 80 Finnish subjects (34 male; 46 female) with two different expressions (smiling neutral) per subject. Inspection eigenvalues gives insight into the importance factors affecting shapes, including: biological sex, expression (neutral versus smiling), all other variations. Biological sex shown be reflected in those components at appropriate...
Although genes on the human X chromosome reportedly influence tooth crown morphology, little is known about activation or inactivation systems relevant to morphological variations. We assessed relationships between size and traits in females with Turner syndrome, variants of which include complete absence one chromosome, lack short arm (Xp), duplication long arms (Xq), then estimated functions Xp Xq process unilateral during development. The mesiodistal buccolingual diameters maxillary first...
