Akleyin E, Yavuz Y, Yardımeden A. Three-Dimensional Modeling and Quantitative Assessment of Mandibular Volume in Ectodermal Dysplasia: A Case Series. MEDICINA (KAUNAS, LITHUANIA) 2024; 60:528. [PMID: 38674174 PMCID: PMC11051706 DOI: 10.3390/medicina60040528] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/11/2024] [Revised: 03/08/2024] [Accepted: 03/21/2024] [Indexed: 04/28/2024]
Abstract
Background and Objectives: Ectodermal dysplasia (ED)-a genetic disorder-is characterized by severe tooth deficiency. We compared the mandibular volume and the sagittal and horizontal mandibular widths between patients with ED (ED group) and individuals without tooth deficiency (control group) using three-dimensional modeling. We hypothesized that the mandibular volume differs in ED cases owing to congenital tooth deficiency. Materials and Methods: We used previously obtained cone-beam computed tomography (CBCT) images of 13 patients with ED. The control group data comprised retrospective CBCT images of patients of similar age and sex with a skeletal relationship of class 1. Further, using the three-dimensional image analysis software, the tooth crowns were separated from the mandible, the mandible was reconstructed and the gonion-to-gonion distance in the mandible was marked, the distance to the menton point was measured, and the distance between the two condyles was measured and compared with the control group. Results: Overall, 46.2% and 53.8% of the participants were men and women, respectively. In the ED group, the mean age of the participants was 15.46 (range, 6-24) years, and the mean number of mandibular teeth was 4.62. Notably, the edentulous mandible volume of the ED group (27.020 mm3) was statistically significantly smaller than that of the control group (49.213 mm3) (p < 0.001). There was no difference between the two groups in terms of the marked points. For data analysis, the Shapiro-Wilk test, independent samples t-test, and Mann-Whitney U test were used. Conclusions: It has been considered that mandible volume does not develop in ED cases because of missing teeth. Modern practices, such as the CBCT technique and three-dimensional software, may be effective in identifying the true morphologic features, especially in patients with genetic syndromes affecting the maxillofacial structure.

Abstract
Background Dental implants in the recent past have become indispensable in restoring loss of space and support as well as aiding the aesthetics. Although in practice for a few years there is no consensus on the protocols for placement and usage of dental implants in growing jaws. Objective The present study aims to evaluate evidence-based literature on single or multiple dental implant placements in children(up to 17 years) and to identify areas lacking and gaps in knowledge. The quality assessment tool,namely AMSTAR-2, will also aim to evaluate the quality of said research around paediatric dental implants. Design The study was prospectively registered on the Open Science Framework https://osf.io/e59bt/?view_only=ec8fb69455c240ecbfc7379734784bf7.For source selection, electronic searches were performed on MEDLINE, EMBASE, Scopus databases as well as Google Scholar for all English language systematic reviews and meta analysis on dental implants placed on children up to 17yrs of age by 2 reviewers, wherein the publications until December 2020 were included. A final dataset of 4 systematic reviews were incorporated and analysed using the AMSTAR-2 grading tool. Results It was seen that only one study showed moderate overall confidence while one low overall confidence as per the AMSTAR-2. The other 2 systematic reviews were of critically low confidence levels. Hence, the existing systematic reviews on the subject are not of high quality. Most of the reviews have no consensus regarding use and placement of implants in growing patients. Conclusion More research and stricter adherence to the quality assessment guidelines is recommended for all future systematic reviews regarding dental implant in children.

Abstract
Background The craniofacial developmental abnormality can significantly complicate the oral rehabilitation of patients with oligodontia. This case report describes an interdisciplinary approach that took 7 years to successfully treat a young patient with non-syndromic oligodontia and midface deficiency. Case presentation A 14-year-old patient with complex oral and maxillofacial conditions and diagnosis of oligodontia presented to our clinic. In addition to 4 retained deciduous teeth and congenitally missing 10 permanent teeth, dentofacial findings included maxillary and malar deficiency with a concave facial profile, Angle Class III malocclusion, and poor dental esthetics. The interdisciplinary treatment included pre-surgical orthodontic decompensation, high Le Fort I maxillary osteotomy, postsurgical orthodontic therapy, osseous ridge augmentation using recombinant human bone morphogenetic protein-2 (rhBMP-2), interim removable partial denture, dental implant installation, interim implant prostheses, and final prosthetic rehabilitation. Conclusions The successful treatment of patients with oligodontia and complex dentofacial abnormalities requires the close and orderly collaboration among orthodontist, oral maxillofacial surgeon, and prosthodontist. Within the limitations of this case report, presented interdisciplinary approaches may optimize the oral rehabilitation outcome in patients with similar clinical challenges. A prospective clinical investigation is desired to verify the benefit of presented interdisciplinary approach.

Comparison of the Pharyngeal Airway Volume Between Patients With Ectodermal Dysplasia and Unaffected Controls: A Cone-Beam Computed Tomography Study. J Oral Maxillofac Surg 2020; 78:1629.e1-1629.e9. [PMID: 32417317 DOI: 10.1016/j.joms.2020.04.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2019] [Revised: 04/09/2020] [Accepted: 04/09/2020] [Indexed: 11/20/2022]
Abstract
PURPOSE Ectodermal dysplasias (EDs) are a diverse set of hereditary conditions in which 2 or more ectodermal structures develop abnormally. The purpose of this study was to use cone-beam computed tomography (CBCT) scans to measure the pharyngeal airway volume and minimum cross-sectional area (MC) among patients with ED and compare them with healthy controls. PATIENTS AND METHODS The pretreatment CBCT scans of 9 individuals with ED and 61 controls were analyzed. Lateral cephalograms were created from the CBCT volumes and then traced and compared between the 2 groups. Airway volumes were evaluated by Dolphin 3D software (Dolphin Imaging, Chatsworth, CA) to compare the total pharyngeal volume, nasopharyngeal volume, oropharyngeal volume, hypopharyngeal volume, and MC. The mean airway volumes of the 2 groups were compared, and the odds ratio and relative risk of having an MC of less than 100 mm2 in the ED group were calculated. RESULTS Intraclass correlation analysis showed excellent inter-rater reliability. All cephalometric features of controls were within the norms of patients with ideal skeletal-dental relationships. Patients with ED displayed significantly lower values for SNA (angle between sella-nasion and nasion-A point) (P = .018), ANB (angle between nasion-A point and nasion-B point) (P = .002), L1-MP (angle between long axis of mandibular incisor and gonion-menton plane) (P = .013), and L1-NB (distance between mandibular incisor and perpendicular line between nasion and B point) (P < .001). Although the ED group exhibited slightly smaller airway volumes for all subregions, the differences were not statistically significant for total pharyngeal volume, nasopharyngeal volume, oropharyngeal volume, hypopharyngeal volume, or MC (P > .05). The odds of having an MC of less than 100 mm2 were almost 3 times greater among ED patients, and the relative risk of an MC of less than 100 mm2 among ED patients was double that of controls. CONCLUSIONS Although the craniofacial structures of individuals with ED are characterized by maxillary and midface deficiency, the airway volumes among affected individuals may not be significantly different from those of unaffected controls. However, patients with ED displayed a higher risk of having an MC of less than 100 mm2, which may be of clinical significance and warrants further investigations with larger samples.

Abstract
Acne is a disease unique to humans and is associated with sebaceous glands that are found at high density on the scalp, forehead and face. Despite being a near universal problem in adolescence, the reason why such troublesome sebaceous glands exist at all is not well understood. Some interesting theories have been postulated including roles for skin maintenance, immunological function and perhaps even pheromones, but pre-pubertal skin which has sebaceous glands that are largely inactive, is healthy. Dystocia, obstructed labour, is unique to humans and no other animal has as much trouble giving birth. This is thought to reflect the relatively large human foetal head and proportionally small maternal pelvis. Noting the high density of sebaceous glands on the face, chest and back; these are exactly the same structures that pose the greatest obstruction during childbirth. Sebaceous glands develop after the fourth month of gestation and are large and well-developed at birth. Sebum production is also relatively high at birth. Having extra lubrication at these sites would help make the baby more slippery for birth conferring a selective advantage to successful delivery, as does the presence of the vernix caseosa, a white creamy substance, unique to humans that coats new-born infants. It is proposed that the sebaceous glands that cause acne are present on the face and forehead as they confer a selective advantage by 'lubricating' the widest parts of the new born baby to ease the passage of childbirth. Later in life, sebaceous glands may be inappropriately and pathologically primed, driven by a combination of hormones, diet and lifestyle to create acne.

Abstract
OBJECTIVE Quantitative research indicate increased anxiety and poorer mental health related quality of life (QoL) in individuals with oligodontia (congenital absence of six or more teeth). The aim of this qualitative study was to complement and explore the individuals' experiences of life and oral rehabilitation, hopefully improving the care for these patients. MATERIAL AND METHODS Twelve participants (6 females, 6 males, aged 21-48) with oligodontia and experiences of comprehensive dental treatments, consented to participate in a semi-structured interview. The questions in the interview guide were based on previous research and clinical experience and included both open (i.e. how is your life?) and specific questions (i.e. do health care personnel know enough about your condition?). The interview transcripts were coded and analysed using a phenomenological method of analysis. The Regional Ethics Committee approved the study. RESULTS The following themes grew out of the data; 'feeling of being different', 'the burden of treatment', 'shared decision-making', 'treatment increases self-esteem' and 'use of coping strategies'. Psychological distress and reduced QoL seemed to be related to negative aspects of the themes, which covered unacceptable aesthetics, reduced orofacial function, the long-term process of oral rehabilitation, and negative experiences with healthcare services. The informants used problem focused and emotionally focused strategies to meet these challenges. Finalizing oral rehabilitation and shared decision making were positive aspects of the themes. CONCLUSION All themes expressed by the participants were of importance for experienced QoL and psychological distress, and should be acknowledged by health care personnel when planning and performing treatment.

Abstract
Hypohidrotic ectodermal dysplasia (HED) is a rare congenital disorder that associates with dental manifestations of anodontia, hypodontia, and atrophic alveolar ridges. Although the disorder does not affect the life expectancy of the patient, it poses tremendous challenges on the patient's physical and psychosocial development. Early and multidisciplinary dental care can benefit HED children's development and improve their quality of life. This study presents two cases addressing the dental management continuously for 10 to 13 years in the dental school clinics. The keys to long-term success of the oral care program for HED patients at different age phases are reviewed and discussed, which can be summarized as early intervention, multidisciplinary collaborative care, and continuous recall.

Abstract
The ectodermal dysplasias are a heterogenous group of diseases, which have one or more anomalies of the hair, teeth, nails, and sweat glands. Hypohidrotic ectodermal dysplasia (HED) is the most common type and is usually transmitted as an X-linked recessive trait. It is characterized by classical triad of hypotrichosis, anhidrosis/hypohidrosis, and hypodontia/anodontia. Here, we describe an Indian boy affected with HED and rare features including ankylosis of temporomandibular joint and cleft palate.

Abstract
Ectodermal dysplasia and sickle cell anaemia are inherited disorders that affect, respectively, the tissues derived from the embryonic ectoderm and the production of erythrocytes by the bone marrow. The simultaneous occurrence of both disorders is extremely rare. This is a case of both ectodermal dysplasia and sickle cell anaemia reported in a 6-year-old. The patient had been diagnosed with sickle cell anaemia for only six months when he sought treatment presenting with the following: hypotrichosis, dry skin, periocular hyperpigmentation, protruding lips, hypodontia, and morphologically altered teeth. The clinical features combined with his medical history led to the diagnosis of ectodermal dysplasia. Dentists should be prepared to recognise patterns that escape normality to aid in the diagnosis of systemic changes, even in patients with other previous diagnoses.
