A 2.5-year-old intact male Irish setter was presented for a draining tract associated with the right mandibular first molar tooth (409). Conscious oral examination yielded two draining tracts associated with the right mandibular first molar tooth. No obvious missing teeth or other gross abnormalities associated with the oral cavity were observed. Upon anesthetized radiographic evaluation, the presence of an unerupted, abnormally positioned, supernumerary premolar tooth was observed. The following article describes the extraction of the right mandibular first molar tooth (409) as well as the unerupted supernumerary premolar tooth with associated supernumerary root and the diagnostic approach taken for this uncommon abnormality.

Teeth are biological markers of maturity, and their eruption into the oral cavity is an essential milestone in an individual's life. Multiple factors have been considered to play a role in the pattern of tooth eruption, including dental caries, fluorides and congenital conditions such as Down's syndrome. The aim of the paper was to determine the time of eruption of permanent teeth amongst children aged between five and ten years, visiting the Dental College in Mangalore. A survey was conducted among children aged between 5 to 10 years visiting A.B. Shetty Memorial Institute of Dental Sciences Deralakatte, Mangalore. Each child included in the study was screened by clinical examination for the erupted and erupting permanent teeth. A parent/guardian accompanying a child was interviewed and their data were recorded. The study revealed that the first tooth to erupt was the left mandibular first molar, with a mean age of eruption at 6.4 years. A slight early eruption of teeth was noticed in the left side of the jaw compared to the right side in the present study. The first permanent tooth to erupt in the oral cavity is the left mandibular first molar and there is a slight delay in the eruption of the maxillary lateral incisor in the study population.

Mandibular First Molar

The missing of permanent first molars influences the occlusal status and dental health. The purpose of this study was to determine the prevalence of missing first molar teeth in a selected population of Shiraz, Iran. Methods. A total of 2206 panoramic views of patients aged from 7 to 75 years old were inspected for missing of permanent first molars. Patients were categorized into five age groups: from 7 to 15, 16 to 30, 31 to 45, 46 to 60, and more than 60 years old. Data were categorized according to sex, age, and number of lost teeth using SPSS software. Results. No first molar was missing in 59.9% of the cases, 17.05% had lost one, 10.4% had lost two, 7.2% had lost three, and 5% were missing all four of their permanent first molars. The mandibular first molar was the most commonly lost tooth, and the left side in both jaws was more affected than the right side. There was a positive relation between age and missing first molar. Conclusions. A missing first molar is a common finding in southern Iran population. Due to the important role of permanent first molars in occlusion, more education and dental care is recommended to preserve these teeth.

Abstract Objective To compare the accuracy of complete-arch scans and quadrant scans obtained using a direct chairside intraoral scanner. Material and methods Intraoral scans were obtained from 20 adults without missing teeth except for the third molar. Maxillary and mandibular complete-arch scans were carried out, and 4 quadrant scans for each arch were performed to obtain right posterior, right anterior, left anterior, and left posterior quadrant scans. Complete-arch scans and quadrant scans were compared with corresponding model scans using best-fit surface-based registration. Shell/shell deviations were computed for complete-arch scans and quadrant scans and compared between the complete-arch scans and each quadrant scans. In addition, shell/shell deviations were calculated also for each individual tooth in complete-arch scans to evaluate factors which influence the accuracy of intraoral scans. Results Complete-arch scans showed relatively greater errors (0.09 ~ 0.10 mm) when compared to quadrant scans (0.05 ~ 0.06 mm). The errors were greater in the maxillary scans than in the mandibular scans. The evaluation of errors for each tooth showed that the errors were greater in posterior teeth than in anterior teeth. Comparing the right and left errors, the right side posterior teeth showed a more substantial variance than the left side in the mandibular scans. Conclusion The scanning accuracy has a difference between complete-arch scanning and quadrant scanning, particularly in the posterior teeth. Careful consideration is needed to avoid scanning inaccuracy for maxillary or mandibular complete-arch, particularly in the posterior area because a complete-arch scan might have potential error than a quadrant scan.

A 32-year-old Chinese man without significant medical history presented with a 2-month history of worsening lumbosacral back pain radiating to the groin and left lower extremity. He also described a shooting pain in the sciatic nerve distribution that began with and was exacerbated by alcohol consumption, a rare but known symptom of Hodgkin lymphoma (HL). On exam, an anterior chest wall mass was noted. Radiographic evaluation of an anterior mediastinal mass showed osseous erosion into the manubrium. MRI of the lumbar spine showed diffuse osseous disease of the lower thoracic and lumbar spine with extension into the right sacroiliac joint and S2 neural foramen without vertebral body collapse or stenosis. Tissue biopsy revealed nodular sclerosis HL, stage IVB IPS2. The patient was primary refractory to ABVD (adriamycin, bleomycin, vinblastine, dacarbazine) therapy. Salvage ICE (ifosfamide, carboplatin, etoposide) chemotherapy was used and then followed by non-myeloablative haploidentical bone marrow transplant was performed on 5 March 2019.

Antemortem domestic pig (Sus scrofa domesticus) dental pathology literature is sparse. This observational descriptive study evaluated 23 client-owned pigs that while sedated/anesthetized for routine annual care had intraoral dental radiographs and an oral examination performed. Age, gender, weight, and breed for each pig were recorded. Oral examination and radiographic findings were reviewed to create a comprehensive list of dental abnormalities identified. Descriptive statistics were performed to summarize the data. The study population included 14 castrated males and 20 Vietnamese pot-bellied mini-pigs. The median age was 3 years (range 2-12 years), and the median weight was 39 kg (range 11-140 kg). The most common finding was missing teeth (21/23 pigs); the first premolar tooth was the most likely to be absent (64/106 missing teeth). Periodontal disease was common (20/23 pigs). Advanced stages primarily affected the first molar teeth frequently in the form of a mucogingival defect. Supernumerary roots were discovered on the maxillary canine teeth in female pigs only (10/25 teeth with supernumerary roots). The most common persistent deciduous tooth was the maxillary second incisor (15/19 persistent deciduous teeth). Non-age or gender related open apices were most likely associated with mandibular first and second incisor teeth (26/96 teeth with open apices). Tooth resorption was also identified (7/23 pigs). The study findings prove that pet pigs commonly have dental pathology; therefore, thorough oral examinations with intraoral radiographs should be included in porcine routine health care regimens.

Introduction: Non-syndromic tooth agenesis defined as developmental absence of more than one tooth that appears as independent congenital oral trait. Its prevalence, pattern and distribution rates vary by populations. The aim of this study was to identify the pattern and distribution of tooth agenesis in permanent dentition among IIUM dental polyclinic patients. Materials and Methods: 3481 patients aged 12 to 60 years who attended IIUM Dental Polyclinic from April 2016 until April 2017 was evaluated. 33 hypodontia and 2 oligodontia were ruled out. Patients were required to undergo clinical and radiographic examinations. Results: On an average, two teeth were missing per patients. Excluding third molar, the prevalence of population under study was 1.005%. Half of the total cases showed missing a single tooth (45.7%), whereas the others ranged from two until nine. The most common missing tooth in maxillary and/or mandibular are lateral incisors (28%) followed by second premolars (26.67%) and first premolars (25.33%). There was no significance difference in missing tooth between male and female (p=0.48). More missing teeth identified at maxilla (54.67%) compared to mandible (45.33%). More teeth were found missing on the right side (54.67%), on the posterior region (53.33%) and also unilaterally (71.42%). Tooth anomalies such as peg-shaped tooth (8.57%) and microdontia (5.71%) were found in some cases. Conclusion(s): In conclusion, mild hypodontia is considered as the most common tooth agenesis. The prevalence studied population was less than the previous studies in Malaysia and lateral incisors were identified as the most common missing tooth.

<p>Recurrent Aphthous Stomatitis (RAS) is a disorder in the oral cavity, with a characterized symptom as ulceration, recurrent and very painfull. The etiology is idiopathic, with multifactorial predisposition. Exfoliative cheilitis is a persistent lesion on the lip, with a characterized cracking and desquamative, with crustae and inflammation. An elderly male (72 yrs) suffered with ulcer on his oral cavity, cracking lips and pain on both of his cheeks, skin, since 5 years ago. The pain is recurrent. On the clinical examination, there were some desquamation, both on the skin and vermilion border, whether on the inner lips (labial fold mucosa), there were ulcers with diameter about 1 cm. The laboratory test was within normal limits, except the LED was 40 mm/hour (n:&lt;15). The diagnosis was Recurrent Aphthous Stomatitis (RAS) for the ulcer and Exfoliative cheilitis for the cracking lips. The treatment he received was a gargle liquid, topical corticosteroid and supplement. The skin’s disorder was revered to the skin and genital disease department, for further management. As a dental general practioner, had to be very careful and familiar for every changes that may be occur both in the outer or inner oral cavity. Other disorder that need refferal, had to be done with team work, to the colleague from the right connection.</p>

Abstract Background Cardiac masses are rare entities and often diagnostically challenging. When incidentally found multimodality diagnostic approach is warranted for further characterization and evaluation of its contribution to the patient’s symptoms. Case report 62-year-old male, smoker, with a history of non-Hodgkin lymphoma treated with radiation and chemotherapy 10 years ago, was admitted due to subacute myocardial infarction. Coronary angiogram showed subacute occlusion of partly collateralized RCA, subsequently treated with dilatation and stenting. Echocardiography revealed signs of dilated cardiomyopathy with severely reduced left ventricular ejection fraction (EF 20%), that could be due to chemotherapy-related cardiotoxicity. On admission CTA was performed to exclude aortic dissection since the patient presented with very severe chest pain radiating to the back. It showed a heterogeneous formation within the right ventricle (RV) extending along the interventricular septum from the apex towards the tricuspid annulus, appearing to involve interventricular septum as well. According to the imaging characteristics the mass was suspected to be a liposarcoma (Figure A). With contrast echocardiography hypoechogenic formation in the RV on parasternal long-axis view could be visualized (Figure B). Due to previous history of malignancy PET scan was performed that revealed hypometabolic RV mass, suggesting a benign tumor, without any sign of metastasis. We decided for percutaneous biopsy that was done under intracardiac echocardiography (ICE) guidance using the view from the RV towards RV outflow tract (Figure C). Histology revealed proliferation of mature adipocytes, either orthotopic or multiplied (Figure D). To exclude well-differentiated liposarcoma FISH (fluorescent in situ hybridization) with amplification of MDM2 gene was undertaken, confirming benign lesion, most probably cardiac lipoma. It was concluded that the mass was an incidental finding, not related to the patient’s symptoms and not causing any functional disturbances; therefore surgical therapy could be avoided. Conclusion While echocardiography remains the first-line imaging modality, multimodality diagnostic approach is mandatory for evaluation and treatment decision of a newly-discovered cardiac mass. Histology provides definitive diagnosis and ICE could be helpful for guiding percutaneous biopsy, thus avoiding invasive open-heart procedures. Figure.

ABSTRACT Objective: The objective of the following study is to investigate the mandibular vertical asymmetry in a group of patients with early unilateral mandibular first molar extractions. Materials and Methods: Mandibular asymmetry index measurements (condylar, ramal and condylar-plus-ramal) were performed on the panoramic radiographs of a study group including 51 patients (mean age: 18.60 ± 1.11 years) and a control group of 51 patients (mean age: 18.53 ± 1.29 years). Group I included patients with a unilateral mandibular first molar extracted before the age of 12 years. Group II included patients with no extractions and had excellent Class I relationships, no missing teeth and slight or moderate anterior crowding. A paired t-test was used to determine possible statistically significant differences between the sides for the measurements. Student's t-test was used for the comparison of asymmetry index values between the groups and genders. Results: No group showed statistically significant sex-or side-specific differences for posterior vertical height measurements. Condylar asymmetry index and ramal asymmetry index measurements were not statistically different between the groups, while condylar-plus-ramal asymmetry index (CRAI) measurements were statistically different between the groups (P = 0.019). Conclusions: A slight difference for CRAI value was found in patients with early unilateral mandibular first molar extractions.
