OBJECTIVES
This article will provide an overview of the clinical presentation, treatment considerations, and sequencing of treatment for a patient with amelogenesis imperfecta (AI). The different types and subgroups of AI will be described, focusing on Type I hypoplastic form of the condition.
OVERVIEW
Patients with AI all have abnormal enamel formation but some may also present with vertical dysgnathia, anterior open bite, and posterior crossbite. A case report demonstrates the sequencing and implementation of necessary orthodontic and prosthodontic treatments, beginning in the mixed dentition and ending with esthetic and functional permanent restorations in the permanent dentition.
CLINICAL SIGNIFICANCE
AI is a disorder of tooth enamel formation but may also affect the face, jaw relationship, occlusion, compromised esthetics, and can potentially cause psychological damage due to the appearance of the teeth. Treatment of AI should be initiated at a young age.

This prospective study examined a population of 520 urban and rural children aged 5 to 9 years. Every 2−4 weeks, the clinical symptoms accompanying primary tooth replacement such as a cough, a runny nose, pain, and body temperature were assessed in each child’s medical records. The authors were able to show in a statistically significant manner that the frequency, time, and type of cough were strongly related to the type of erupting teeth (p < 0.001 for each relationship). A cough dependent on the type of erupting teeth was observed in 86% to 92% of the examined children, with a morning bronchial cough being connected with an eruption of the lower teeth, and an eruption of the upper teeth producing an all-day pharyngeal cough caused by mucus secretions dripping down the back of the throat. A statistically significant relationship was also confirmed between the type of erupting teeth and the incidence of a runny nose (p < 0.001), the frequency of a runny nose (p < 0.001), and the time when runny nose symptoms occurred (p < 0.001). This study shows that the period when primary dentition is replaced with permanent teeth in children is characterized by a physiological cough and a runny nose.

Traumatic dental injuries comprise a number of the dental emergency patients who are often seen after hours or on an unscheduled basis in a dental practice environment. Although there are a variety of traumatic dental injuries that can occur, each with their own recommended treatment protocols, the initial evaluation and diagnosis of the traumatized dentition make up a critical aspect of the management of these cases. This article will highlight the key components of a thorough and efficient examination process of the traumatized dentition to include (1) documenting an accurate history of the events causing the injury, (2) performing a systematic clinical examination to include the use of clinical photographs and pulp sensibility tests, (3) obtaining appropriate radiographic images and scans, (4) understanding some considerations unique to evaluating young patients with traumatic injuries, and (5) recognizing the importance of having accurate and thorough documentation of these types of cases. Once the evaluation and diagnosis phase has been completed, the necessary treatment protocols can be initiated in an appropriate manner.

BACKGROUND
The aim of this study was to determine the clinical and inflammatory response patterns for individual siblings diagnosed with grade C molar-incisor pattern periodontitis (C-MIP) and between the related siblings within families.
METHODS
Sixty-nine siblings within 28 families with moderate-to-severe C-MIP were included. Clinical parameters were evaluated for symmetry regarding the affected type of teeth, side and/or arch, and bone loss pattern. The protein concentrations from in vitro whole blood cultures for 14 different lipopolysaccharide-stimulated inflammatory markers were correlated with the extent and severity of disease, within an individual sibling and among siblings within a family.
RESULTS
A similar disease pattern was observed among all siblings and within families. The most common teeth affected were first molars and incisors or first molars only within the permanent dentition and only molars within the primary dentition (p < 0.001). Symmetry involving molars was higher than in incisors in siblings, regardless of arch or side affected (p = 0.020). Arc-shape/vertical bone defects were the most common (p = 0.006) and higher symmetry was found for these defects in the permanent dentition (p = 0.005). Positive correlations were found between age, clinical attachment loss, and percent affected sites with several inflammatory markers. The inflammatory responses for several inflammatory markers were correlated within and among families (p < 0.050). Specifically, the intraclass correlation coefficient within families was highest (>0.5) for interleukin (IL)-8, IL-6, and IL-10.
CONCLUSIONS
Families with C-MIP presented similar patterns of disease. The level of an inflammatory response to bacteria seemed to play a role in the extent and severity of this disease, exemplified by the high degree of correlation in these families.

Review
Root canal treatment (RCT) has been considered the conventional standard for the management of teeth with carious pulp exposure, particularly in mature teeth presenting with symptoms. Following a better understanding of the histopathology of deep carious lesions, the histology of the cariously exposed pulp and the healing potential of the inflamed pulp, vital pulp therapy (VPT) is increasingly adopted around the world for the management of permanent teeth with clinical signs and symptoms indicative of irreversible pulpitis. Furthermore, VPT became a recognized treatment modality by the European Society of Endodontology (ESE) and the American Association of Endodontists (AAE) by virtue of its high success rates reported in outcome studies using contemporary hydraulic calcium silicate-based cements. However, proper case selection, strict asepsis, capping materials and good coronal seal are mandatory for success. The aim of this paper is to review the biological basis for VPT in symptomatic teeth with carious pulp exposure and to report on the outcome of pulpotomy in teeth with clinical diagnosis of irreversible pulpitis.

Regional odontodysplasia (ROD) is a rare developmental anomaly with distinctive clinical, radiographical and histological findings, affecting both primary and permanent dentitions. The teeth with ROD have an atypical morphology and are usually discolored, with either delayed eruption or complete failure to erupt. Radiographically, the affected teeth have a "ghostly" appearance, with marked radiolucency and decreased radiodensity, showing a thin outline of enamel and dentin, which appear hypomineralized histologically, with poorly structured dentinal tubules and enamel prisms. Calcifications are frequently found in the pulp chambers of the affected teeth. This case report discusses a three-year-old girl who presented with ROD in her mandible as well as the clinical and radiographical features, and treatment of the condition.

Review
Traumatic dental injury (TDI), one of the common dental diseases, is defined as acute injuries to tooth hard tissues, dental pulp and/or periodontal tissues caused by sudden forces. Based on the Guidelines for the Management of TDI by International Association of Dental Traumatology (2012) and the Recommended Guidelines of the American Association of Endodontists for the Treatment of TDI (2013) for the permanent teeth, and combined with the authors' clinical experiences, the contemporary classification and clinical perspective of TDI were introduced in detail. Dental clinicians should understand and master the international guidelines for the management of TDI, including proper diagnosis, standardized treatments and regular follow-up, so as to obtain the favorable outcomes.

OBJECTIVES
To compare mandibular relative anchorage loss (RAL) under reciprocal anchorage between first and second premolar extraction cases in bimaxillary protrusion mild crowding cases treated using clear aligner therapy (CAT).
MATERIALS AND METHODS
Adult patients who met the following criteria were included: treated using CAT with bilateral mandibular premolar extractions and space closure using intra-arch reciprocal anchorage. RAL was defined as the percent molar mesial movement relative to the sum of molar mesial plus canine distal movement. Movements of the mandibular central incisor (L1), canine (L3), and first molar (L6) were measured based on superimposition of the pre- and post-treatment dentition and jaw models.
RESULTS
Among the 60 mandibular extraction quadrants, 38 had lower first premolar (L4) and 22 had lower second premolar (L5) extracted. L6 mesial movement was 2.01 ± 1.11 mm with RAL of 25% in the L4 extraction group vs 3.25 ± 1.19 mm with RAL of 40% in the L5 extraction group (P < .001). Tooth movement efficacy was 43% for L1 occlusogingival movement, 75% for L1 buccolingual inclination, 60% for L3 occlusogingival movement, and 53% for L3 mesiodistal angulation. L1 had unwanted extrusion and lingual crown torquing whereas L3 had unwanted extrusion and distal crown tipping, on which the power ridges or attachments had little preventive effect.
CONCLUSIONS
The average mandibular reciprocal RAL is 25% or 40% for extraction of L4 or L5, respectively, in CAT cases. A RAL-based treatment planning workflow is proposed for CAT extraction cases.

OBJECTIVES
This study developed and validated a deep learning-based method to automatically segment and number teeth in panoramic radiographs across primary, mixed, and permanent dentitions.
METHODS
A total of 6,046 panoramic radiographs were collected and annotated. The dataset encompassed primary, mixed and permanent dentitions and dental abnormalities such as tooth number anomalies, dental diseases, dental prostheses, and orthodontic appliances. A deep learning-based algorithm consisting of a U-Net-based region of interest extraction model, a Hybrid Task Cascade-based teeth segmentation and numbering model, and a post-processing procedure was trained on 4,232 images, validated on 605 images, and tested on 1,209 images. Precision, recall and Intersection-over-Union (IoU) were used to evaluate its performance.
RESULTS
The deep learning-based teeth identification algorithm achieved good performance on panoramic radiographs, with precision and recall for teeth segmentation and numbering exceeding 97%, and the IoU between predictions and ground truths reaching 92%. It generalized well across all three dentition stages and complex real-world cases.
CONCLUSIONS
By utilizing a two-stage training framework with a large-scale heterogeneous dataset, the automatic teeth identification algorithm achieved a performance level comparable to that of dental experts.
CLINICAL SIGNIFICANCE
Deep learning can be leveraged to aid clinical interpretation of panoramic radiographs across primary, mixed, and permanent dentitions, even in the presence of real-world complexities. This robust teeth identification algorithm could contribute to the future development of more advanced, diagnosis- or treatment-oriented dental automation systems.

This study examined the migratory status/ethnic inequities in dental caries in school children aged 4-9 years ( = 1388) and the impact of the Children's Oral Health Program in the Municipality of Bilbao in the Basque Country Region, Spain. Using the 2017 Children's Oral Health Survey, log binomial regression was used to quantify the association of parental immigration status/ethnicity with tooth decay for (1) the primary and the permanent dentitions, separately, in children 4-9 years old; and (2) for the permanent dentition in children aged 7-9 years. Compared with Spanish children, Spanish Roma and immigrant children had a higher probability of tooth decay in primary and permanent teeth after adjustment. Similarly, Spanish Roma and immigrant children had a higher probability of caries experience in primary and permanent teeth. In children aged 7-9 years, Spanish Roma children had a greater probability of tooth decay and caries experience ( index ≥ 1; PR: 6.20; 95% CI: 3.18, 12.12; and PR: 4.52; 95% CI: 2.46, 8.32; respectively) compared with Spanish Children. These associations were not observed in immigrant children. This study shows that parental immigration status and/or ethnicity affect caries outcomes in immigrant and Roma children in both primary and permanent dentition.
