Abstract Aim The purpose of this report is to present two cases of totally impacted maxillary deciduous molars, considered a rarity in dental practice. Background Primary tooth impaction is quite rare during the development of primary dentition. Various factors contribute to the impaction of a deciduous tooth, including anklyosis, congenitally missing permanent teeth, defects in the periodontal membrane, trauma, injury of the periodontal ligament, precocious eruption of the first permanent molar, defective eruptive force, or a combination of these factors. Reports Case #1 An 18-year-old male presented with a complaint of spontaneous repetitious pain in the maxillary right premolar region. The maxillary right second premolar was clinically absent. Panoramic and periapical radiographs revealed an impacted second premolar close to the inferior wall of the maxillary sinus and an impacted deciduous molar deeply embedded in bone within the maxillary sinus. Case #2 A 14-year-old girl presented with a complaint of crowding of the maxillary teeth. The maxillary right second premolar and the maxillary permanent canines were clinically absent. A panoramic radiograph revealed an impacted maxillary right second premolar and an impacted deciduous molar embedded within bone close to the inferior wall of the maxillary sinus. Summary The total impactation of deciduous teeth is a rare condition, and few cases have been reported in the literature. The condition generally affects the mandibular second deciduous molar and the maxillary first deciduous least often. In this paper, two cases of totally impacted maxillary deciduous molars are reported. Citation Gündüz K, Muğlali M, Inal S. Total Impaction of Deciduous Maxillary Molars: Two Case Reports.

Objective: To assess primary molars early loss in mixed dentition prevalence. Method: A study was carried out in children aged 6 to 12 years. Deciduous molar loss was considered early when it occurred before Nolla stage 6 (full formed crown) of the permanent successor or one year before its physiological exfoliation. Periapical radiographs were obtained to verify the presence of the permanent successor and the level of root formation, as well as the need for placement of fixed space maintainer lingual arch or Nance button. For the study of frequency distribution of early dental loss in relation to gender and dentition, we used the Chi-square test of 5% probability level and the non-parametric Mann-Whitney test for adequate statistical analysis. Results: Of the 315 children examined, 159 (50.47%) were male and 156 (49.52%) were female. Only 25 (7.9%) presented multiple dental losses in the posterior region, 19 in the lower arch and 6 in the upper arch. In the inferior one there was predominance of first and second deciduous molars loss. There was no difference in the association between genders and the occurrence of multiple dental losses (χ² (1) = 0.03, p>0.05). Conclusion: The prevalence of deciduous teeth premature loss was of 7.9% and the most affected teeth were the first and second molars in the lower arch. Lingual arch space holders were installed in 6 children, who will remain with it until the permanent successors erupt into the oral cavity.

Avulsion of a primary tooth is a disturbing type of traumatic injury occurring in children. Paediatric dentists are likely to encounter a child with an avulsed primary tooth routinely in their clinical practice. Tooth avulsions are common in permanent teeth. However, avulsions can be seen even in primary teeth. The question of replantation of the avulsed tooth has been a focus of debate and controversy since years. The primary and most important factor in these injuries is to calculate the riskbenefit ratio keeping the underlying permanent tooth in mind. Utmost importance has to be given on the care of development and normal eruptive movements of the succedaneous tooth. This is mandatory if any treatment like replantation is to be done. The amount of primary root resorption, stage of development of the underlying permanent tooth, type of splinting to be done etc. needs a lot of attention. Many authors have given their opinions regarding the replantation of primary teeth based on the type of tooth avulsed. Moreover, the evidence might differ as to whether or not replantation might alter the difficulty levels for the eruption process of succedaneous tooth. There is not much evidence regarding the benefits and risks of replantation post avulsion of primary teeth. However, individual authors have reported a successful outcome in their case reports. This article reports a review on avulsed primary teeth replantation. This would enable the dentists to analyze the risks and benefits associated with replantation, thereby guiding them to arrive at the best clinical decision.

Tooth impaction is defined as any tooth that fails to erupt into a normal functional position and remains unerupted beyond the time at which it should normally erupt. Reports of impaction and eruption failure in primary teeth are relatively rare compared to permanent teeth. We report 2 rare cases where the second premolar was located on the occlusal side of the impacted mandibular second primary molar. In the first case, the succedaneous permanent tooth erupted after extraction of the primary tooth, fenestration, and traction. In the second case, the succedaneous permanent tooth erupted without fenestration or traction. Although the etiology of the tooth displacement was unknown in both cases, inhibition of the eruptive movement of the primary molar may have been associated with displacement of the succedaneous permanent premolar.

Primary teeth should be preserved until their normal exfoliation time so as to maintain arch length and function in order to provide proper guidance for the eruption of  permanent teeth , enhance esthetics and mastication, prevent aberrant tongue habits, aid in speech  and prevent the psychological effects associated with tooth loss. Pulpectomy consists of removing the pulp tissue associated with micro-organisms and debris from the canal and obturating with resorbable filling material. Success rate of endodontic therapy depends on many factors like  familiarity with the complexity of primary tooth canal systems, their formation and resorption pattern, obturating material as well as obturation technique used that is capable of densely filling the entire root canal system and providing a fluid tight seal from the apical segment of the canal to the cavosurface margin in order to prevent reinfection. This review article basically focuses on various obturating techniques used in deciduous teeth with their comparison, pros and cons.

AbstractA review of numerous case reports was made, in order to demonstrate the possibilities for treatment of dental disorders in patients with Cleidocranial dysplasia (CCD). In this paper, our own report, including a diagnosis of the effect on the auditory system, is presented. In addition to the triad of CCD symptoms that include hypoplastic or aplastic clavicles, impacted and supernumerary teeth, delayed closure of fontanelles and cranial sutures, impairment of the hearing system resulting in conductive hearing loss also occurs. Our own report is based on the case of a 12-year-old CCD patient, in whom Cone Beam Computed Tomography (CBCT) revealed the presence of 12 supernumerary teeth. Furthermore, a clinical examination pointed to the presence of retained deciduous teeth and a delayed eruption of permanent teeth. Orthodontic-surgical procedures were implemented, in accordance with the literature. During the course of the orthodontic treatment, a decrease in auditory sensitivity was observed, for which reason hearing tests were also performed. Conductive hearing loss was detected. As such, it is important to remember that in such cases, auditory check-ups need to be performed between the many surgical and orthodontic interventions, which usually last a few years.

Impaksi gigi terjadi karena gigi gagal untuk erupsi secara sempurna pada posisinya akibat terhalang oleh gigi lain maupun jaringan lunak atau padat di sekitarnya. Gigi yang sering mengalami impaksi adalah gigi geraham ketiga rahang bawah, gigi kaninus rahang atas, dan gigi premolar kedua. Impaksi premolar sering terjadi karena pencabutan prematur dari gig geraham desidui. Gigi premolar pertama jarang terjadi impaksi dibandingkan premolar kedua. Tujuan laporan kasus adalah untuk memaparkan penatalaksanaan perawatan untuk mengkoreksi impaksi gigi premolar pertama mandibula menggunakan alat cekat teknik Begg tanpa prosedur bedah. Pria 21 tahun mengeluhkan gigi yang berjejal pada rahang atas dan rahang bawah. Gigi kaninus desidui kiri rahang atas dan rahang bawah belum tanggal. Diagnosis pasien adalah Maloklusi Angle Klas II  divisi 2 bimaksiler protrusif dengan hubungan skeletal klas II, gigi anterior maksila retrusif, disertai impaksi gigi premolar pertama mandibula kiri. Perawatan dilakukan dengan menggunakan alat cekat teknik Begg dan pencabutan gigi desidui, Kesimpulan, impaksi gigi premolar pertama mandibula dapat tercapai pada tahap pertama teknik Begg tanpa pendekatan tindakan bedah, tahap selanjutnya yang akan dicapai adalah tahap memperbaiki inklinasi aksial gigi.Treatment Of Class II Division 2 Angle Malocclusion With Mandibular Premolar Tooth Impaction Using Begg Technique. Tooth impaction is a tooth that fails to erupt perfectly to its position because of the other tooth, surrounding soft or hard tissue that blocks its eruption. Premolar often fails to erupt due to a premature extraction of deciduous molar. This case study aims to illustrate the treatment of mandibular first premolar impaction using Begg technique for fixed appliance. The experiment was conducted to a 21 year-old male patient who complained about his crowding of upper and lower teeth, also the persistence of his upper and lower left deciduous canine. The case was diagnosed as class II division 2 angle malocclusion with bimaxillary protrusion with class II skeletal relation, and maxillary anterior teeth retrusion. The left mandibular of first premolar teeth was impacted. The treatment using Begg technique has helped to fix the appliance with the extraction of the deciduous teeth. From the evaluation, it can be concluded that the treatment of impacted mandibular first premolar is achieved on the first stage of Begg technique without surgical approach. The next objective of the treatment is to correct the teeth axis.

Abstract Objective: To evaluate the prevalence of dental anomalies in patients with agenesis of second premolars and compare the findings with the prevalence of these anomalies in the general population. Materials and Methods: A Brazilian sample of 203 patients aged 8 to 22 years was selected. All patients presented agenesis of at least one second premolar. Panoramic and periapical radiographs and dental casts were used to analyze the presence of other associated dental anomalies, including agenesis of other permanent teeth, ectopia of unerupted permanent teeth, infraocclusion of deciduous molars, microdontia of maxillary lateral incisors, and supernumerary teeth. The occurrence of these anomalies was compared with occurrence data previously reported for the general population. Statistical testing was performed using the chi-square test (P < .05) and the odds ratio. Results: The sample with agenesis of at least one second premolar presented a significantly increased prevalence rate of permanent tooth agenesis (21%), excluding third molars. Among the sample segment aged 14 years or greater (N = 77), occurrence of third-molar agenesis (48%) exceeded twice its normal frequency. Significant increases in occurrence of microdontia of maxillary lateral incisors (20.6%), infraocclusion of deciduous molars (24.6%), and distoangulation of mandibular second premolars (7.8%) were observed. Palatally displaced canine anomaly was also significantly elevated (8.1%). Conclusion: The results provide evidence that agenesis of other permanent teeth, microdontia, deciduous molar infraocclusion, and certain dental ectopias are the products of the same genetic mechanisms that cause second-premolar agenesis.

: Most conventional treatments for neurodegenerative diseases fail due to their focus on neuroprotection rather than neurorestoration. Stem cell‐based therapies are becoming a potential treatment option for neurodegenerative diseases as they can home in, engraft, differentiate and produce factors for CNS recovery. Stem cells derived from human dental pulp tissue differ from other sources of mesenchymal stem cells due to their embryonic neural crest origin and neurotrophic property. These include both dental pulp stem cells [DPSCs] from dental pulp tissues of human permanent teeth and stem cells from human exfoliated deciduous teeth [SHED]. SHED offer many advantages over other types of MSCs such as good proliferative potential, minimal invasive procurement, neuronal differentiation and neurotrophic capacity, and negligible ethical concerns. The therapeutic potential of SHED is attributed to the paracrine action of extracellularly released secreted factors, specifically the secretome, of which exosomes is a key component. SHED and its conditioned media can be effective in neurodegeneration through multiple mechanisms, including cell replacement, paracrine effects, angiogenesis, synaptogenesis, immunomodulation, and apoptosis inhibition, and SHED exosomes offer an ideal refined bed-to-bench formulation in neurodegenerative disorders. However, in spite of these advantages, there are still some limitations of SHED exosome therapy, such as the effectiveness of long-term storage of SHED and their exosomes, the development of a robust GMP-grade manufacturing protocol, optimization of the route of administration, and evaluation of the efficacy and safety in humans. In this review, we have addressed the isolation, collection and properties of SHED along with its therapeutic potential on in vitro and in vivo neuronal disorder models as evident from the published literature.

Abstract Background Mesenchymal stem cells isolated from the dental pulp of primary and permanent teeth can be differentiated into different cell types including osteoblasts. This study was conducted to compare the morphology and osteogenic potential of stem cells from exfoliated deciduous teeth (SHED) and dental pulp stem cells (DPSC) in granular hydroxyapatite scaffold (gHA). Preosteoblast cells (MC3T3-E1) were used as a control group. Methodology The expression of stemness markers for DPSC and SHED was evaluated using reverse transcriptase-polymerase chain reaction (RT-PCR). Alkaline phosphatase assay was used to compare the osteoblastic differentiation of these cells (2D culture). Then, cells were seeded on the scaffold and incubated for 21 days. Morphology assessment using field emission scanning electron microscopy (FESEM) was done while osteogenic differentiation was detected using ALP assay (3D culture). Results The morphology of cells was mononucleated, fibroblast-like shaped cells with extended cytoplasmic projection. In RT-PCR study, DPSC and SHED expressed GAPDH, CD73, CD105, and CD146 while negatively expressed CD11b, CD34 and CD45. FESEM results showed that by day 21, dental stem cells have a round like morphology which is the morphology of osteoblast as compared to day 7. The osteogenic potential using ALP assay was significantly increased (p < 0.01) in SHED as compared to DPSC and MC3T3-E1 in 2D and 3D cultures. Conclusion gHA scaffold is an optimal scaffold as it induced osteogenesis in vitro. Besides, SHED had the highest osteogenic potential making them a preferred candidate for tissue engineering in comparison with DPSC.
