Migration describes the movement of an unerupted tooth within the bone when normal eruption is prevented and the tooth leaves its normal site of development. This report describes a case of distal migration and ectopic eruption of the mandibular first premolar in an 8.5-year-old boy. Following early extraction of the primary second molar, the first premolar migrated distally through the extraction site of the primary second molar and erupted into occlusion just mesial of the permanent first molar.
The curved planes of the human dentition seen in the sagittal view, the mandibular curve of Spee and the maxillary compensating curve, have clinical importance to modern dentistry and potential relevance to the craniofacial evolution of hominins. However, the mechanism providing the formation of these curved planes is poorly understood. To explore this further, we use a simplified finite element model, consisting of maxillary and mandibular "blocks", developed to simulate tooth eruption, and forces opposing...
Ectopic pancreas is a congenital developmental anomaly that may be caused by embryologic errors. The pathogenetic details of ectopic pancreas remain unclear, but it has gradually been determined to originate at the gene level. DNA errors during embryological development cause ectopic pancreas. Ectopic pancreas is generally asymptomatic and harmless throughout the patient's entire life; in very rare cases, however, it can be symptomatic and harmful, causing pain, fever, bleeding, and other adverse effects. W...
Coexistence of bullous pemphigoid (BP) and vitiligo vulgaris (VV) is very rare. We present a unique case of BP associated with VV in a 76-year-old Japanese man, in which BP eruption developed exclusively on preexisting VV regions. The patient was referred to us with a 3-month history of blistering eruption with severe pruritis on the right forearm and left lower limb. In addition, he had been suffering from a widespread depigmented eruption on the trunk and extremities for at least 20 years. Curiously, the ...
This study aimed to evaluate the unerupted mandibular second premolar (MnP2) angulation in individuals with different tooth agenesis in Turkish population.
A 14-year-old girl underwent extraction of an ankylosed primary left second molar as requested by her orthodontist. The developing mandibular left second premolar (tooth 20) was unintentionally removed during extraction of the primary molar. Immediate measures were taken to reimplant tooth 20. Recall appointments over the next 10 years included monitoring of tooth 20. The patient also was followed up closely by her orthodontist during this time. Tooth 20 was monitored for proper eruption, root development, ...
This case report demonstrates a positive outcome of the adjuvant use of fragile fracture (FF), which is a technique used to harvest Dental pulp stem cells (DPSCs), and Platelet Rich Plasma (PRP) in a mandibular premolar (tooth 44) with a completely formed root that was transplanted into a surgically created socket and which maintained pulp vitality and function.
Ectopic hepatic tissue is due to an uncommon failure of embryological liver development. The incidence of ectopic liver has been reported to be anywhere from 0.24% to 0.47% and a prevalence rate of 0.47% as diagnosed at laparotomy or laparoscopy. We report a case of Ectopic Hepatic tissue attached to the gallbladder wall that was discovered during a laparoscopic cholecystectomy.
Ectopic pregnancy is defined as a pregnancy that occurs outside of the uterine cavity (ACOG Committee on Practice Bulletins, 2018 ). Ectopic pregnancy is occasionally diagnosed with MRI. Particularly, when ultrasound is nondiagnostic, it is essential that radiologists are able to recognize findings of ectopic pregnancy on MRI in the emergent setting. This novel case report demonstrates specific MR imaging signs recently proposed in the literature to help identify a tubal gestational sac, the most common ...
The mandibular third premolar (P) exhibits substantial differences in size and shape among hominoid taxa, and displays a number of discrete traits that have proven to be useful in studies of hominin taxonomy and phylogeny. Discrete traits at the enamel-dentine junction (EDJ) can be accurately assessed on moderately worn specimens, and often appear sharper than at the outer-enamel surface (OES). Here we use microtomography to image the P EDJ of a broad sample of extant apes, extinct hominins and modern human...
Pulpal calcifications can present problems in endodontic treatment. This micro-CT study examined the removal of calcifications by a multisonic cleaning system in uninstrumented mandibular molar distal canals. The teeth were accessed and distal canals located and their patency ensured. Micro-CT images were obtained, and 15 teeth with distal canal calcifications were selected. The volume of distal canals and calcifications were calculated from the micro-CT images before and after cleaning with the GentleWave ...
Craniofacial duplication is a rare congenital anomaly. A case of hemi-mandibular duplication with an accessory oral cavity is presented with along with first-time reported pre- and postnatal MRI, surgical approach and a literature review. MRI clearly depicts the ectopic tooth buds and parotid aplasia in this condition, features that are diagnostic of partial facial duplication. MRI is diagnostic for this condition and can be useful to avoid misdiagnosis of a facial mass.
Cone-beam computed tomography (CBCT) can show an uncommon mandibular incisive canal that cannot be detected by panoramic radiography, which is used preoperatively to form the initial plan of the size and length of an implant fixture for surgical placement in the mandibular interforaminal area. Determination of the position and anatomical configuration of the mandibular incisive canal is challenging. The purpose of this case report is to discuss anatomical variations in the mandibular incisive canal and the ...
This article reports a case of a large osteolytic lesion in the mandible, mostly associated with the apices of the premolars, and suspected as having a non-endodontic origin because the 2 premolars responded positively to the cold sensibility test. The distal border of the lesion reached the mesial root of the first molar, which also had a small lesion in its distal aspect. Cone-beam computed tomography revealed that the large lesion communicated with the small molar lesion. Because the large lesion was sus...
Fixed Drug Eruption (FDE) is a drug reaction involving the skin and less commonly the mucosal membranes. Tamsulosin is an alpha-1 adrenergic receptor blocker used to treat benign prostatic hyperplasia. Dizziness and headache are among its most common side effects (Singapore Med J, 2018;59:336). Although cutaneous drug eruption has been reported with other alpha-1 adrenergic receptor blockers.
The mandible is a crucial organ in both clinical and biological fields due to the high frequency of congenital anomalies and the significant morphological changes during evolution. Primary cilia play a critical role in many biological processes, including the determination of left/right axis patterning, the regulation of signaling pathways, and the formation of bone and cartilage. Perturbations in the function of primary cilia are known to cause a wide spectrum of human diseases: the ciliopathies. Craniofac...
Cases of ectopic production of adrenocorticotropic hormone are considerably rare, but persistent in clinical practice. Extremely rare cases of ectopic production, such as via pheochromocytoma secretion, require special clinical attention and prior knowledge. It is important to understand the diagnostic algorithm for identifying ectopic sources of adrenocorticotropic hormone production.
Dislocation of mandibular condyles can occur following excessive mouth opening or traumatic injury to the temporomandibular joint. It can also occur during general anesthesia that at times may go un-noticed in the modern-day theater setup. Here, we describe a case of bilateral dislocation of mandibular condyle following orotracheal intubation for general anesthesia. Right condyle was dislocated into temporal fossa.
The aim of this study was to establish a radiographic method for detecting distal radioulnar joint instability intraoperatively. We created three successive instabilities in 12 intact Thiel-fixed upper limb specimens: lesion of the triangular fibrocartilage complex, Galeazzi injury and Essex-Lopresti injury. We made three-dimensional scans of the wrists in pronation and supination with a mobile C-arm. We used four validated measurement methods to quantify ulnar migration in the standard axial planes: the ra...
What factors identify the optimal surgical technique when a distal wedge procedure is indicated at a terminal maxillary or mandibular molar site?
We present an unusual case of a distal metaphyseal femur insufficiency fracture in an adolescent with a history of multiple low-energy appendicular fractures. A genetic workup was significant for a variant of unknown significance to the Col1A1 gene.
Chronic distal biceps tendon ruptures are rare and conservative or operative treatment options are suitable. There is a consensus in the literature in case of acute traumatic ruptures the operative refixation should be preferred. Disagreement exists in the best way of care of old ruptures (> 4 weeks) of distal biceps tendon. Several kinds of refixation possibilities up to tendon grafts are described. Aim of this publication is showing an overview of the literature of the approved methods in reconstruction...
Chondrosarcoma is a malignant tumor originated from cartilage cells. The most common sites of chondrosarcoma are pelvis, femur and ribs. The temporo-mandibular joint (TMJ) chondrosarcoma is extremely rare, with approximately 30 cases reported in worldwide.
The ultimate treatment approach for cervical ectopic pregnancy remains controversial. Gestational age, serum β-hCG levels, fetal cardiac activity presence and the patient's claim for fertility preservation are the major challenges for method of choice in each individual case. Medical treatment may be a favorable option for the treatment of late diagnosed cases, as well as the early ones.
