The aim of this study was to evaluate the biomechanical impact, in terms of stress and displacement, at the level of a mandibular overdenture, on four mini dental implants (MDIs) after the loss of an implant. A three-dimensional virtual model was obtained by scanning the overdenture, and a biomechanical analysis was carried out, using the finite element method (FEM). The displacements of the overdenture and the equivalent von Mises stresses were evaluated using logarithmic scales. In the case of a mandibular overdenture on four MDIs inserted in the interforaminal area, the frontal loading generated the lowest values for the von Mises stresses, and the bilateral loading generated the least displacement when two implants were inserted in the canine area and two in the molar area. The highest von Mises stress was observed during frontal loading in the situation of the mandibular overdenture on four MDIs, two of which were inserted in the canine area and two in the molar area, following the loss of an implant in the canine area. The largest displacement was noted in the mandibular overdenture on four interforaminal MDIs during unilateral loading, following the loss of a distally inserted implant. The FEM analysis showed aspects that correlated with clinical observations, with predictive value. The concentration of von Mises stresses, and the occurrence of some displacements of the prosthodontic restoration, can explain the emergence of some complications in the overdenture’s biodynamics, and the increased risk of fracture. Complications can be prevented by choosing a certain number of implants and a topographical distribution correlated with biomechanical aspects, and by proposing a correct occlusal scheme with optimal functional loading.

This study aimed to assess the perception of dentists on the complications associated with prosthodontic treatments with acrylic dentures and overdentures in partially or complete edentulous patients. The study analyzed the complications of acrylic dentures and overdentures using a questionnaire with 24 open or closed questions, with single or multiple answers. The participants were 63 dentists, mostly women (77.8%), aged between 30 and 39 years old (52.4%), more than half of them with a clinical experience of less than 15 years. The main complications encountered were: lesions of the oral mucosa (52.4%), lack of maintenance (44.4%) or stability of dentures (39.7%), fracture of acrylic bases (14.3%), and detachment of attachment systems (44.4%). The complete maxillary acrylic dentures fractured most often (38.1%), frequently on the midline (58.7%), the main causes being accidental fall, masticatory stress, or lack of stability of the dentures. The most common intervention to correct the complications of dentures was the repair of fractured acrylic bases (33.3%). The study exposed that dentists are aware of the possible complications of acrylic dentures, which they correlate with the peculiarities of oral structures, but also with some deficiencies of prosthodontic restorations, materials and technologies. Maxillary acrylic dentures, overdentures, and partial acrylic dentures have a high risk and fracture rate, but the use of new technologies and materials can reduce the complications rate of acrylic dentures and overdentures.

Background/Objectives: This retrospective observational study evaluated associations among dentition type, age, systemic conditions, and oral pathology in pediatric patients. Methods: A six-month retrospective analysis was conducted in a specialized pediatric hospital. Patients (n = 155; 0–18 years) were grouped as clinically healthy with oro-maxillofacial diseases or with systemic diseases. Data included dental/periodontal status, anomalies, gingival bleeding index, IOTN score and oral mucosal conditions. Statistical tests (chi-square, ANOVA, and correlations) were applied. Results: Chronic gingivitis was most frequently associated with primary dentition. Caries and root debris were more frequent in ages 4–6, while acute gingivitis appeared in younger children. Orthodontic treatment need increased with age, especially in mixed dentition. Periodontal diseases were most often linked to digestive pathologies. Conclusions: Oral health in children showed associations with age, dentition type, and systemic conditions. Findings highlight associations rather than causation, underscoring the importance of prevention, early monitoring, and age-appropriate interdisciplinary management.

This study aimed to highlight the perceived associations between general and oral pathology, among clinicians of different specialties. Data was collected through a questionnaire with 22 questions, with single or multiple answers, to 88 dentists, general practitioners, or pediatricians. The majority of participants were women (89.8%), aged between 30 and 39 years (52.3%), with a professional experience mostly under 10 years (61.3%). Many doctors considered that there was an association between oral and general pathologies (39.8%). The most common general pathologies associated with oral pathology were digestive disorders (n=21, 23.9%), followed by cardiovascular, genetic, endocrine and metabolic, neuropsychiatric, respiratory, hematological, immunological, and oncological pathologies. Tooth decay was mainly found in patients with digestive, respiratory, or neuropsychiatric disorders, and periodontal disease was more common in patients with obstetric disorders. Diseases of the oral mucosa, such as canker sores and gingivostomatitis, were more common in patients with digestive pathology, endocrine and metabolic, or reproductive disorders. The study pointed out that physicians, regardless of their medical training, often observed a relatively rich general pathology associated with oral conditions. It is important to differentiate between primary and secondary oral pathology, associated with general pathology and medication, establishing a correct diagnosis of the disease and treatment according to general or oral diseases and their manifestations.

Hypothyroidism is one of the most common thyroid dysfunctions in pediatric age. Congenital hypothyroidism affects between 1: 2,000 and 1: 4,000 newborns. Acquired hypothyroidism may be primary, when hormonal dysfunction is caused by thyroid, and central involvement, when there is a hypothalamo-pituitary involvement. Undifferentiated, in pediatric age, hypothyroidism has negative effects on the entire body, affecting growth, puberty and school performance. The aim of the study was to assess the effects of congenital hypothyroidism on orodental patterns in children. The study group consists of 39 pediatric age patients (20 females and 19 males) with thyroid insufficiency. The diagnosis of the underlying condition (hypothyroidism) was established based on the clinical examination data, in conjunction with the dosing of thyroid hormones (thyroxine, triiodothyronine) and thyroid stimulating hormone. Case distribution according to dento-maxillary changes: delay in eruption - 32 children, dental malformations (anodontia and ectopia) - 9 children, dental caries - 7 children. The data obtained in the study are consistent with those in the literature. There is a positive correlation between bone age and dental age, which allows assessment of dental age in a child with congenital hypothyroidism as an element of development and maturation.

Objectives. To assess the type and distribution of dento-periodontal traumas in mixed dentition in a group of children aged 3-9 years who seek consultation and treatment in the Pedodontics Department of the Faculty of Dentistry. Material and methods. Retrospective descriptive observational descriptive study performed on 114 children (67 boys) aged 3-9 years, (mean age - 5.65 ± 1.45 years) with dento-periodontal trauma to temporary teeth (dt) and permanent teeth (PT), which occurred in Bucharest Pedodontics Clinic during 2015-2019. The recorded data were obtained from the emergency register of this clinic. The distribution of patients according to age, sex, environment, etiology, age and location of trauma and number of affected teeth was assessed and the distribution of affected teeth was analyzed according to the type of dentition affected, topography of affected teeth and emergency treatment performed. Results. The most frequent traumas for dt were registered at the age of 3 years, and for DP at the age of 7-8 years. Boys were more affected than girls (58.77% and 41.23%, respectively; NS, p > 0.05). 63% of patients came from urban areas and 37% from rural areas. Most injuries (64.03%) were caused by accidental falling children. 50.87% of patients presented to the clinic less than 24 hours after the accident. 55.27% of the traumas occurred in the internal environment. Most patients (87.71%) had 1 or 2 affected teeth. 41% of the traumas were at DP and 59% at dt. At DP there were 21.57% dental injuries and 19.12% periodontal injuries. At dt 11.76% were dental traumas and 47.54% periodontal. The upper frontals were the most affected teeth at both dentitions. Conclusions. Dento-periodontal injuries are a common pathology in this age group and it is important to make the persons around children aware of the importance of their prevention.
