Specific oral and maxillofacial identifiers in panoramic radiographs used for human identification.

Radiographically assisted dental identification is an important means for individual identification. Specific identifiers help to quickly filter some of the possible corresponding AM and PM images at the beginning. The study seeks specific oral and maxillofacial identifiers in panoramic radiographs. A total of 920 panoramic radiographs from 460 live patients were used. The most recent radiograph served as the surrogate post-mortem (PM) record of an unidentified person, and the earliest radiograph served as the ante-mortem (AM) record of the same person. We evaluated the following four groups of identifiers of the images: (1) dental morphology, tooth number, and position; (2) dental treatment and pathology; (3) morphological identifiers of the jaw; and (4) pathological identifiers of the jaw. The ratio of each identifier being identified simultaneously in the AM and PM databases was determined. Specific identifiers were defined as those that appeared at low frequency (ratio: 0%-0.250%). A total of 18 specific oral and maxillofacial identifiers were determined. The specific identifiers were a retained deciduous tooth (0.011%), S-shaped deflection of a tooth root (0.012%), distal deflection of tooth root (0.017%), inverted impaction (0.018%), malposition (0.038%), supernumerary teeth (0.061%), mesial deflection of tooth root (0.092%), microdontia (0.136%), buccal/lingual impaction (0.188%), cementoma (0.002%), hypercementosis (0.002%), continuous crown (0.004%), pulp calcification (0.023%), attrition (0.030%), residual root (0.106%), root resorption (0.137%), implant (0.156%), and osteomyelitis (0.002%). Identifiers of the teeth and jaw can be used for human identification, and dental identifiers are more specific than identifiers of jaw.

Equine Oral Endoscopy.

Oral endoscopy is a valuable addition to the equine dental examination process. It enables veterinarians to visualize subtle oral disorders and is a useful client education tool. There are several commercially available oral endoscopic systems on the market. Practitioners can also assemble their own systems. An oral endoscope is used to perform a thorough and systematic oral examination and to visualize normal oral structures as well as oral disorders. It is also used to guide instrument placement during oral surgeries and other dental procedures.

Teeth Impaction and Structural Teeth Anomalies.

Dentists and oral and maxillofacial radiologists have used periapical, occlusal, panoramic, and cephalometric radiographs for many years for diagnosing dental anomalies, especially before orthodontic or surgical treatment. Cone beam computed tomography was developed in recent years especially for the dental and maxillofacial region. Thus it has become the imaging modality of choice for many clinical situations, such as the assessment of dental impaction and structural teeth anomalies or other associated diseases and disorders (e.g., Gardner's syndrome, cleidocranial dysplasia). This article reviews different aspects of dental impaction and its possible effects on adjacent structures such as external root resorption, marginal bone loss, as well as describing structural dental anomalies. It provides a systematic analysis of their characteristic features and imaging findings for general radiologists to achieve a precise diagnosis and an optimal interpretation.

Cross-Sectional Imaging of Third Molar-Related Abnormalities.

Third molars may be associated with a wide range of pathologic conditions, including mechanical, inflammatory, infectious, cystic, neoplastic, and iatrogenic. Diagnosis of third molar-related conditions can be challenging for radiologists who lack experience in dental imaging. Appropriate imaging evaluation can help practicing radiologists arrive at correct diagnoses, thus improving patient care. This review discusses the imaging findings of various conditions related to third molars, highlighting relevant anatomy and cross-sectional imaging techniques. In addition, key imaging findings of complications of third molar extraction are presented.

Unexpectedly low levels of dental morphological asymmetry suggesting developmental resilience amongst living Jordanians: A cone beam computed tomography study.

The objective was to determine the degree of fluctuating asymmetry in the expression of 13 dental morphological traits among adult Jordanians. Cone beam computed tomography images for the dentitions of 150 adult Jordanians (67 males, 83 females; age range = 18-58, mean ages 28.2, SD = 10.0 years) were studied in 2017. The traits were classified using the Arizona State University dental anthropology system, and dichotomized according to the most widely accepted criteria to define trait presence. Asymmetry was assessed using three different methods: percentage of discordance including bilateral absence cases (PDIBAC), percentage of discordance excluding bilateral absence cases (PDEBAC), and inter-side correlation (ISC) using Kendall's tau coefficient. Fisher's exact test was used to assess sexual dimorphism in the degree of asymmetry. The mean PDIBAC and the mean ISC for all the traits considered are 4.1% and 0.837, respectively. For traits observed on key teeth (mesial members of teeth districts) the mean PDIBAC and the mean ISC are 3.0% and 0.860, respectively; and for those observed on variable teeth (distal members of teeth districts) the mean PDIBAC and the mean ISC are 6.5% and 0.783, respectively. No statistically significant difference was found in the degree of asymmetry between sexes. The overall low degree of asymmetry found in the present sample (4.1%) compared to the world range of 5-15% may indicate great ability of its individuals to buffer the adverse effects of environmental stresses affecting the living Jordanians during early tooth development.

Atrofia extrema vertical y horizontal combinada en sectores posteriores mandibulares. Uso de implantes cortos y expansión de cresta en dos fases con implantes transicionales / Extreme Vertical And Horizontal Atrophy In Mandibular Posterior Sectors. Use Of Short Implants And Split Crest In Two Phases With Transitional Implants. Clinical Case

El objetivo del presente trabajo es la presentación de un caso clínico en el que mostramos dos técnicas quirúrgicas para resolver la atrofia ósea en sentido horizontal. En la implantología actual nos enfrentamos cada vez con más frecuencia a casos con extremas reabsorciones óseas que nos obligan a implementar distintas técnicas quirúrgicas para lograr el éxito de nuestros tratamientos con implantes dentales. La coexistencia de atrofias verticales y horizontales complica la resolución de estos casos con éxito, aunque cada vez con mayor frecuencia nos enfrentamos a este tipo de situaciones más complicadas debido a que los pacientes demandan el tratamiento implantológico incluso en casos muy severos. Por ello, no es infrecuente tener que utilizar técnicas como la expansión de cresta o los implantes cortos de forma combinada en algunas situaciones. En el siguiente caso clínico mostramos una paciente con reabsorción extrema mandibular en ambos sectores posteriores con los dos tipos de reabsorción descritos anteriormente: las zonas posteriores con reabsorción extrema vertical y un abordaje con implantes cortos y una zona anterior con reabsorción extrema horizontal tratada con Split en dos fases mediante implantes expansores transicionales

The objective of this work is the presentation of a clinical case in which we show two surgical techniques to solve the horizontal bone atrophy. In the advanced implant dentistry, different surgical techniques would be required for the successfull treatment of patients presenting severe alveolar ridge atrophy. The presence of vertical and horizontal atrophies increases drastically the difficulty of the clinical case where several surgical techniques will be needed. Therefore, it is not uncommon to performe techniques like the alveolar ridge expansion and short implants in the same mandible or maxilla. The following clinical case presented an advanced horizontal and vertical alveolar atrophy in the right and left posterior regions of the mandible. The treatment plan included the use of short implants to treat the vertical atrophy and the two-stage alveolar ridge split to treat the horizontal atrophy

Convolutional neural networks for dental image diagnostics: A scoping review.

OBJECTIVES: Convolutional neural networks (CNNs) are increasingly applied for medical image diagnostics. We performed a scoping review, exploring (1) use cases, (2) methodologies and (3) findings of studies applying CNN on dental image material. SOURCES: Medline via PubMed, IEEE Xplore, arXiv were searched. STUDY SELECTION: Full-text articles and conference-proceedings reporting CNN application on dental imagery were included. DATA: Thirty-six studies, published 2015-2019, were included, mainly from four countries (South Korea, United States, Japan, China). Studies focussed on general dentistry (n = 15 studies), cariology (n = 5), endodontics (n = 2), periodontology (n = 3), orthodontics (n = 3), dental radiology (2), forensic dentistry (n = 2) and general medicine (n = 4). Most often, the detection, segmentation or classification of anatomical structures, including teeth (n = 9), jaw bone (n = 2) and skeletal landmarks (n = 4) was performed. Detection of pathologies focused on caries (n = 3). The most commonly used image type were panoramic radiographs (n = 11), followed by periapical radiographs (n = 8), Cone-Beam CT or conventional CT (n = 6). Dataset sizes varied between 10-5,166 images (mean 1,053). Most studies used medical professionals to label the images and constitute the reference test. A large range of outcome metrics was employed, hampering comparisons across studies. A comparison of the CNN performance against an independent test group of dentists was provided by seven studies; most studies found the CNN to perform similar to dentists. Applicability or impact on treatment decision was not assessed at all. CONCLUSIONS: CNNs are increasingly employed for dental image diagnostics in research settings. Their usefulness, safety and generalizability should be demonstrated using more rigorous, replicable and comparable methodology. CLINICAL SIGNIFICANCE: CNNs may be used in diagnostic-assistance systems, thereby assisting dentists in a more comprehensive, systematic and faster evaluation and documentation of dental images. CNNs may become applicable in routine care; however, prior to that, the dental community should appraise them against the rules of evidence-based practice.

Application of optical coherence tomography in clinical diagnosis.

BACKGROUND: Optical coherence tomography (OCT) is a non-invasive diagnosing tool used in clinics. Due to its high resolution (<10um), it is appropriate for the early detection of tiny infections. It has been widely used in diagnosis and treatment of diseases, evaluation of therapeutic efficacy, and monitoring of various physiological and pathological processes. OBJECTIVE: To systemically review literature to summarize the clinic application of OCT in recent years. METHODS: For clinic applications that OCT has been applied, we selected studies that describe the most relevant works. The discussion included: 1) which tissue could be used in the OCT detection, 2) which character of different tissue could be used as diagnosing criteria, 3) which diseases and pathological process have been diagnosed or monitored using OCT imaging, and 4) the recent development of clinic OCT diagnosing. RESULTS: The literature showed that the OCT had been listed as a routine test choice for ophthalmic diseases, while the first commercial product for cardiovascular OCT detection had gotten clearance. Meanwhile, as the development of commercial benchtop OCT equipment and tiny fiber probe, the commercial application of OCT in dermatology, dentistry, gastroenterology and urology also had great potential in the near future. CONCLUSIONS: The analysis and discussions showed that OCT, as an optical diagnosing method, has been used successfully in many clinical fields, and has the potential to be a standard inspection method in several clinic fields, such as dermatology, dentistry and cardiovascular.

Scintigraphic evaluation of cheek teeth in clinically sound horses.

Dental disorders are one of the top-ranking clinical domains in equine practice. Scintigraphy has emerged as a useful diagnostic imaging modality for equine dental diseases. There is a paucity of the normal scintigraphic uptake and its correlation with age. This prospective, cross-sectional, descriptive and pilot-designed study aimed to describe the radioisotope uptake (RU) patterns of the reserved crown and periodontal bone of the maxillary and mandibular cheek teeth (CT) in clinically sound horses and to evaluate the age effect on RU. For this purpose, 60 horses that underwent a bone scintigraphy for reason unrelated to head were included and divided equally into four age groups. Regions of interests (ROIs) were positioned around alveolar and periodontal bone of each maxillary and mandibular CT including their reserve crown, and a reference ROI positioned at the mandibular ramus. The count per pixel of each ROI was measured using a dedicated software and the RU ratio relative to the reference region was calculated. The results showed that the maxillary and mandibular CT had a standard RU pattern, where it increased from rostral to caudal, and peaked in the middle of dental arcades and decreased slightly towards the last CT. The maxillary CT had a higher RU compared with the mandibular CT, and there was no significant difference in the maxillary and mandibular CT uptake between age groups. This information may aid veterinarians evaluating potentially abnormal dental scintigraphy.

New PCNT candidate missense variant in a patient with oral and maxillofacial osteodysplasia: a case report.

BACKGROUND: Osteodysplasia of the oral and maxillofacial bone is generally accompanied by systemic bone abnormalities (such as short stature, joint contracture) or other systemic abnormalities (such as renal, dermatological, cardiovascular, optic, or hearing disorders). However, it does not always present this way. Recent reports have suggested that genome-wide sequencing is an effective method for identifying rare or new disorders. Here, we performed whole-exome sequencing (WES) in a patient with a unique form of acquired, local osteodysplasia of the oral and maxillofacial region. CASE PRESENTATION: A 46-year-old woman presented to our hospital with the complaint of gradually moving mandibular teeth (for 6 months), changing facial appearance, and acquired osteolysis of the oral and maxillofacial bones, showing mandibular hypoplasia without family history. Upon skeletal examination, there were no abnormal findings outside of the oral and maxillofacial area; the patient had a height of 157 cm and bone mineral density (according to dual energy x-ray absorptiometry) of 90%. Results of blood and urine tests, including evaluation of bone metabolism markers and neurological and cardiovascular examinations, were normal. We performed WES of genomic DNA extracted from the blood of this patient and her mother, who did not have the disease, as a negative control. We identified 83 new missense variants in the patient, not detected in her mother, including a candidate single nucleotide variant in exon 14 of PCNT (pericentrin). Critical homozygous or compound heterozygous variants in PCNT are a known cause of microcephalic osteodysplastic primordial dwarfism type II accompanied by mandibular hypoplasia, which is similar to the maxillofacial phenotype in this patient. CONCLUSIONS: Protein simulations performed using Polymorphism Phenotyping v2 and Combined Annotation Dependent Depletion software indicated that this missense variant is likely to disrupt the PCNT protein structure. These results suggest that this is a new form of osteolysis related to this PCNT variant.

Qafzeh 9 mandible (ca 90-100 kyrs BP, Israel) revisited: µ-CT and 3D reveal new pathological conditions.

OBJECTIVE: The aim of this paper is to provide new insights into growth patterns and health of Mousterian hunter-gatherers dated to ca. 90-100 kyrs B.P. from the Qafzeh site. MATERIALS: An almost complete skeleton, including the mandible from the Qafzeh site (Qafzeh 9). METHODS: Micro-CT and medical imaging techniques are used to explore inaccessible inner structures and to assess the etiology of identified lesion. RESULTS: Mandibular and dental conditions appear to be growth-related skeletal disorders. CONCLUSION: To our knowledge, Qafzeh 9 offers the earliest evidence of associated mandibular and dental pathological conditions (i.e. non-ossifying fibroma of the mandible, pre-eruptive intracoronal resorption and osteochondritis dissecans of the temporomandibular joint) among early anatomically modern humans, and more generally among Middle Palaeolithic hominins in Southwestern Asia. The diagnoses can be added to other growth-related disorders of skulls previously documented from the Qafzeh site (Tillier, 1999; Tillier et al., 2001), suggesting a quite high and exceptional incidence of these conditions compared to those of Palaeolithic populations. SIGNIFICANCE: Identification of pathological conditions in subadults from Eurasia dated to the Middle Palaeolithic is documented less often than in adult skeletons. Hence, new results from immature fossil remains are particularly important to our understanding of the past. SUGGESTIONS FOR FURTHER RESEARCH: This research will be extended to the rest of the skeleton, then to all Qafzeh specimens in order to broaden our understanding of this anatomically modern group.

Evidence-Based Clinical Criteria for Computed Tomography Imaging in Odontogenic Infections.

PURPOSE: Odontogenic infections are a common problem in emergency departments and impose a burden on hospital budgets and provider time. Compounding this is the lack of evidence guiding the patient's initial evaluation. The purpose of this study was to derive evidence-based guidelines for the use of computed tomographic (CT) imaging in the management of odontogenic infections. MATERIALS AND METHODS: A prospective cohort study was designed. Patients with an odontogenic infection presenting to the emergency department from November 1, 2016 to November 30, 2017 were eligible for inclusion. The outcome variable was need for CT imaging, which was based on the location of the abscess. The potential predictor variables were demographics, history items, examination findings, and laboratory values. The association between the outcome and predictor variables was determined using classification and regression tree analysis and standard logistic regression analysis. RESULTS: There were 129 patients who met the inclusion criteria and consented to participation. The patients were 53.5% men and the mean age was 42.5 years. The most common fascial spaces involved were vestibular (58.2%), submandibular (18.6%), pterygomandibular (6.2%), buccal (5.4%), and lateral pharyngeal (5.4%). The classification and regression tree analysis identified mandibular inferior border blunting at the body as the best predictor for necessitating a CT scan and identified a mouth opening smaller than 25 mm as the second best predictor. These 2 predictors had an accuracy of 96.9% for needing a CT scan. The logistic regression analysis identified these 2 variables and odynophagia, floor of mouth induration, and white blood cell count as relevant predictors for needing CT imaging. CONCLUSION: The 2 physical examination findings of mandibular inferior border blunting at the body and restricted mouth opening were found to be strongly associated with the need for CT imaging. Further studies should be directed at validating these criteria in larger multicenter studies.

Dental magnetic resonance imaging for periodontal indication - a new approach of imaging residual periodontal bone support.

OBJECTIVE: The standard imaging techniques used in dentistry consist of two-dimensional radiographic techniques like intraoral periapical (PA) radiographs, bitewings or extraoral panoramic X-rays. Three-dimensional methods, such as cone beam computed tomography (CBCT), are not standard procedures. In several fields of dentistry, such as oral surgery or implantology, dental magnetic resonance imaging (DMRI), a technique without radiation exposure, has already been introduced as a new promising diagnostic tool. The aim of this study was to compare the agreement of DMRI and PA radiographs in measuring residual periodontal bone support. MATERIAL AND METHODS: In this study, the residual periodontal bone support of 21 teeth was investigated and compared with DMRI and PA radiographs by two independent raters. Intra-class correlation coefficients (ICCs) were calculated using the software R to identify the intra-rater and inter-rater agreement of the two modalities. Bland-Altman plots were created to directly compare the two methods. RESULTS: Overall, all calculated ICC values showed an excellent intra-rater and inter-rater agreement (>0.9) for DMRI, as well as PA radiographs. Bland-Altman analysis also showed a strong agreement between both diagnostic methods in this study. CONCLUSIONS: In conclusion, there was a strong agreement between DMRI and PA. Thus, DMRI proved to be a comparable method to PA radiographs for evaluating the proportion of residual periodontal bone support.

Dental Imaging - A basic guide for the radiologist. / Dentale Bildgebung ­ Eine Einführung für den Radiologen.

BACKGROUND: As dental imaging accounts for approximately 40 % of all X-ray examinations in Germany, profound knowledge of this topic is essential not only for the dentist but also for the clinical radiologist. This review focuses on basic imaging findings regarding the teeth. Therefore, tooth structure, currently available imaging techniques and common findings in conserving dentistry including endodontology, periodontology, implantology and dental trauma are presented. METHODS: Literature research on the current state of dental radiology was performed using Pubmed. RESULTS AND CONCLUSION: Currently, the most frequent imaging techniques are the orthopantomogram (OPG) and single-tooth radiograph, as well as computer tomography (CT) and cone beam CT mainly for implantology (planning or postoperative control) or trauma indications. Especially early diagnosis and correct classification of a dental trauma, such as dental pulp involvement, prevents from treatment delays or worsening of therapy options and prognosis. Furthermore, teeth are commonly a hidden focus of infection.Since radiologists are frequently confronted with dental imaging, either concerning a particular question such as a trauma patient or regarding incidental findings throughout head and neck imaging, further training in this field is more than worthwhile to facilitate an early and sufficient dental treatment. KEY POINTS: · This review focuses on dental imaging techniques and the most important pathologies.. · Dental pathologies may not only be locally but also systemically relevant.. · Reporting of dental findings is important for best patient care..

Radicular cyst associated with primary molar: Surgical intervention and space management.

Radicular cysts associated with primary teeth are rare. This case report describes radicular cyst associated with carious primary mandibular second molar in a 5-year-old patient and discusses its surgical intervention, space management, and follow-up for 3½ years.

Use of mineral trioxide aggregate for retreatment of a tooth with large periapical lesion, wide-open apices and vertical root fracture.

Chronic periapical lesions in necrotic teeth with open apex are difficult to manage. The situation becomes more complex if the tooth has a fracture line. This case report describes the management of a traumatised tooth that had already undergone unsuccessful endodontic treatment with a large periapical lesion and open apex along with a fracture line in the root. An attempt was made to save the tooth by using mineral trioxide aggregate (MTA) cement for orthograde filling, retrograde filling and also for sealing of the fracture line. Moreover, the bone defect was filled with autogenous bone harvested from the external oblique ridge. MTA, a bioactive tricalcium silicate cement, has been used in treating complex endodontic cases as it shows promising potential by inducing the biological mechanisms necessary for repair of involved teeth. A 1-year follow-up showed progressive healing as evident by radiographs and lack of any clinical signs and symptoms.

Dentomaxillofacial radiology in Australia and dentist satisfaction with radiology reports.

BACKGROUND: Dentomaxillofacial Radiology (DMFR) is comprised of the smallest cohort of specialists in Australia. A survey was undertaken to assess awareness of DMFR, radiology reporting and referring protocols as well as dental practitioners' satisfaction with their radiology reporting arrangements. METHODS: An original online survey created using Checkbox† was sent to dental practitioners. The survey was promoted on Australian-based dental Facebook forums and emailed to targeted members via Australian professional dental associations. RESULTS: A total of 399 responses were received, with over 80% of respondents aware of DMFR as a specialty. Approximately 40% of practitioners were self-reporting their imaging. There was correlation between increased satisfaction with external reporting and utilization of DMFR services and decreased satisfaction with medical radiology services. More than 90% of general dentists and greater than 85% of dental specialists prefer DMFR reports to medical radiology reports. Approximately 80% of practitioners believed that their satisfaction would change positively if they had access to a DMFR report. CONCLUSION: The research indicates a high degree of self-reporting or non-reporting by dental practitioners. There is low satisfaction with external reporting performed by Medical Radiologists primarily due to a lack of dental knowledge or detail and a preference for DMF Radiology reports.

Association of dental and maxillary sinus pathologies with ear, nose, and throat symptoms.

OBJECTIVES: To investigate the correlation between cone-beam computerized tomography (CBCT) findings in the maxillary sinus, ear-nose-throat (ENT) symptoms and dental pathologies in asymptomatic patients. MATERIALS AND METHODS: A total 81 patients were referred for CBCT and filled a standard ENT visual analog scale (VAS) questionnaire. CBCT images were analyzed for sinus ostium obstruction, Schneiderian membrane thickening, sinus floor turbidity, and the presence of polyps. Dental pathologies were evaluated with the aid of CBCT images, periapical X-rays, and clinical examination. A possible correlation between the CBCT findings and the ENT/dental parameters was examined by applying Student's t test and the chi-squared test. RESULTS: Despite being asymptomatic, most of the 81 patients reported ENT symptoms in the questionnaire, thereby indicating that these symptoms were mainly subclinical. A significant correlation was found between the presence of polyps in the sinus and a decrease in smell/taste. Obstruction of the sinus meatus was associated with coughing; turbidity was associated with ear congestion. Thickening of the Schneiderian membrane showed an association with both coughing and ear congestion. The mean number of missing posterior teeth correlated with postnasal drip and nasal congestion. Periapical pathology was associated with nasal discharge/runny nose. CONCLUSION: The results emphasize the need to evaluate ENT symptoms when radiographic findings are identified in CBCT.
