This research monograph is based on dental casts for 184 white children residing in Massachusetts and Delaware. The topics discussed pertain to tooth size, dental arch size, and positional interrelationships of the teeth in the two arches. On each subject, the investigator had available a series of dental casts "covering the transition from the primary to the secondary dentition" (p. 40). The casts were amassed in part at the Center for Research in Child Health and Development, Boston (Dr. Harold C. Stuart), and in part at a public school in Wilmington, Delaware (Dr. Richard H. Stucklen).

In a mixed longitudinal study, dental arch relationships of 88 consecutive UCLP patients treated at the Nijmegen Cleft Palate Centre were evaluated using the Goslon Yardstick. On the basis of timing of hard palate closure, the patients were divided into four groups. Mean age of hard palate closure in group A (n = 18) was 1.5 years, in group B (n = 26) 4.6 years and in group C (n = 18) 9.4 years. In group D (n = 26, no patient older than 10 years) the hard palate was still open. Four stages of dental development were distinguished; deciduous dentition, early mixed dentition, late mixed dentition and permanent dentition. Reproducibility of scoring with the Goslon Yardstick was good for all stages of dental development. No differences in dental arch relationships were found between the four groups. In 86% of the cases, the dental arch relationships of UCLP patients treated in Nijmegen were acceptable. Pharyngeal flap surgery had minor unfavorable effects on dental arch relationships.

The Relationship

This book is a timely addition to the pediatrician's library. The education, practice and philosophy of the specialty of pediatrics are expanding in understanding of and services for the healthy child. The authors, representing five medical specialties and four nonmedical disciplines, offer contributions to the pediatrician for this progress. The relationship between episodes of illness and the health and development of the child is discussed by Dr. Isabelle Valadian. Examples for illustration are taken from children in the Harvard Longitudinal Study of Child Health and Development. Two chapters will serve as reviews of pediatric information for most pediatricians. The first is a summary of the natural development of immunities and the artificial induction of immunities. The second is a clinical description of physiological conditions in the newborn that are consistent with health. Their clarity and simplicity will serve usefully in teaching.

Aim: The purpose of this investigation was to examine the extent to which arch dimension or tooth size contributes to dental crowding. Materials and Methods: Two groups of dental casts were selected. Each group consisted of 30 pairs of dental casts including equal male and female samples. The first group had Class I malocclusion without crowding. The second group exhibited Class I malocclusion with dental crowding (more than 5 mm space deficiency). The following parameters were measured and used to compare the two groups: individual and collective mesiodistal widths of tooth, dental arch length, as well as buccal and lingual dental arch widths in the canine and molar regions. Results: Statistically significant differences in both tooth widths and transverse arch dimensions (widths) were found between the crowded and the normal groups. The crowded group was found to have a significantly smaller maxillary arch width and larger tooth size when compared with the uncrowded or normal group. There were no significant differences in arch length in the two groups in either the maxilla or the mandible. In comparing the anterior and overall Bolton ratios no significant difference was detected between the crowded and normal groups. Conclusion: The results of this study suggest under under two study groups (Class I skeletal base of crowded and uncrowded group) tooth size has a greater role in developing dental crowding.

ABSTRACT Objective: To compare arch perimeter and teeth size, number, and shape between the two sides of the dental arch—the canine displacement side (DS) and the nondisplacement side (NDS)—in subjects with unilateral palatally displaced canine (PDC). Materials and Methods: Orthopantomograms (OPTs) of 240 subjects with unilateral PDC and 240 OPT matching controls were used. Additionally, study casts of 100 study subjects and 100 controls were used. The age of subjects ranged between 14 and 25 years. Dental casts were digitized and several parameters were recorded. Results: The transverse width from midpalatal line to the buccal segment and the palatal area on the DS was larger than that in the NDS (P < .05 to .001), with no difference in tooth size between both sides. Maxillary second premolars, canines, and lateral incisors in the PDC group were smaller than those in control group. Peg-shaped lateral incisors were significantly more frequent in the study group (P < .001). Conclusions: The transverse width of the DS was larger than that of the NDS. Both sides were generally smaller than those of the control group. Tooth size in the DS was comparable to that in the NDS but smaller than those of the control group. A missing or peg-shaped lateral incisor was the most common reported anomaly.

ABSTRACT Introduction Thalassemia is one of the most common genetic disorders worldwide and presents public health and social challenges in areas of high incidence. Thalassemia major (TM) type is associated with most severe clinical changes. Aim To evaluate dental and oromaxillofacial features of TM. Materials and methods The sample consisted of 54 children and adolescents with TM, 31 males and 23 females, aged 5.5 to 18.3 years (mean age 11.6 ± 3.2 years) and thalassemia-free controls. They were examined for dental caries, oral hygiene, periodontal status, orofacial features, tooth size and dental arch dimensions, dental development, and physical pattern. Clinical, radiographical, and odontometric assessments were carried out. Results Thalassemia major patients were at high risk of dental caries. The average decayed, missing, filled tooth (DMFT) value was 6.26 for 15-year-olds compared with 4.84 in the control group (p < 0.001). Poor oral hygiene and gingivitis were observed in 61.1 and 92.2% of the thalassemic patients respectively. Clinical orofacial features of TM include frontal bossing, saddle nose, and maxillary protrusion, giving a “chipmunk”-like face. Lip incompetence, dental discoloration, and pallor oral mucosa have been noted. Radiographical examination showed the following: thickened frontal bone, thinned mandibular cortex, and maxillary sinus hypoplasia. Class II malocclusion, significant reduction in tooth size and dental arch dimensions, and delay in dental development were evident. Growth retardation was present in 75.9% of the patients. Conclusion Thalassemia major produces a variety of orofacial and systemic complications that increase with age. Early diagnosis and management allow more favorable prognosis and minimize complication. Clinical significance Dental practitioners, especially working in multiracial communities, require understanding of the complications and management of the disease.

Abstract Aim The purpose of this investigation was to examine the extent to which arch dimension or tooth size contributes to dental crowding. Methods and Materials Two groups of dental casts were selected. Each group consisted of 30 pairs of dental casts including equal male and female samples. The first group had Class I malocclusions without crowding or spacing. The second group exhibited Class I malocclusions with severe dental crowding (> a 5 mm space deficiency). The following parameters were measured and used to compare the two groups: individual and collective mesiodistal tooth diameters, dental arch length, as well as buccal and lingual dental arch widths in the canine and molar regions. To compare the two groups the Student's t-test with 95% confidence interval was used. Results Statistically significant differences in both tooth diameters and transverse arch dimensions were found between the two groups. The crowded group was found to have a significantly smaller maxillary arch width and larger tooth size when compared with the uncrowded group. Conclusion The results of this study suggest under equal conditions (a Class I skeletal relationship) tooth size has a greater role in developing dental crowding. Citation Poosti M, Jalali T.

Abstract About 250 million children under age five are at risk of not reaching their developmental potential due to continued exposure to ill health, malnutrition and lack of appropriate learning environments. A large number of initiatives have been launched in recent years to support early childhood development, with home visiting programs increasingly being recognized as a key strategy for improving child wellbeing. However, the most effective ways to reach families in low income settings remain unclear due to the large expense associated with personal family visits. In this project, we assess the effectiveness and equity of a newly developed digital platform designed to deliver evidence-based, individualized parenting support through automated services. The Afinidata platform uses state-of-the art machine learning algorithms to allow caregivers to get answers to questions about child health and development, while also identifying and promoting age- and development-appropriate activities for parents to support their children. We will collaborate with partners in Peru to rigorously assess the reach, impact and cost effectiveness of this digital platform in a poor rural population through a randomized controlled trial. Our work will follow a mixed-methods evaluation approach with repeated feedback into the Afinidata system. A total of 2,400 newborns will be enrolled in a randomized controlled trial in San Marcos, Peru, and followed up for two years. The primary study outcome will be children's healthy development at 24 months of age assessed through the Bayley Scales of Infant and Toddler Development (BSID-III). Secondary outcomes will be systems utilization, program coverage and cost-effectiveness, as well as caregiver satisfaction. If proven effective, this innovative digital platform may increase global access to low-cost parental support -a widely recognized key strategy for improving child well-being.
