Background: The goal of this retrospective study was to determine the prevalence of pulp stones in a Hazaribagh population. Any possible associations between pulp stones tooth type and dental arch were also evaluated.Methods: A total of 4625 teeth of 500 patients were examined in our department who came for diagnostic radiograph of posterior teeth. The presence or absences of pulp stones were recorded.Results: Pulp stones were found in 834 (18.03%) of 4625 teeth detected. The occurrence of pulp stones was most significant in among the age groups of 31-50 years of age.  The pulp stones were significantly higher in permanent maxillary first and second molars.Conclusions: Pulp stones are not only incidental radiographic findings of the pulp tissue but may also be an indicator of some serious underlying disease. On the other hand, they may provide useful information to predict about the susceptibility of patients for other dystrophic soft tissue calcifications such as urinary calculi and calcified atheromas.

The suspended replacement of extracted teeth may disrupt the structural integrity of the whole dental arch, particularly in posterior maxillary or mandibular tooth/teeth. This phenomenon often has consequences of masticatory deficiency and temporomandibular joint disorders. This work aims to assess and measure the overeruption of posterior teeth from panoramic radiographs (OPGs) and its relation to gender, age, tooth type, arch, sides, and cause of tooth loss. A total of 100 OPGs were included in this in vitro study. The level of posterior overeruption was measured in mm using the panoramic digital radiograph machine and its software systems. Other variables such as gender, tooth/teeth involved, arches, and side were considered. All parameter values were inputted to a software program and assessed. P value < 0.05 was considered as statistically significant. Males accounted for 63% of the OPGs. Age groups 18–30 and 31–45 years had the highest frequency and percentage (34%). Approximately 74% of the patients got their tooth/teeth extracted 4–6 years ago. The 0.7–1.2 mm overeruption subgroup had the highest proportion of 41%. The rate of overeruption in mandibular molars was 36%, which was the highest among the subgroups. Males had higher percentage than females in ≥60 and 31–45 age groups (84.65% and 76.5%, respectively), 4–6 years post-extraction time (85.7%), with significant differences, also, mandibular molars (85.0%) and mandibular arches (74.3%) were the higher among males. The highest level of overeruption was 0.7–1.2 mm, and mandibular molars were the most affected type. Significant differences between genders were detected in age groups, years after tooth loss, and arch side but not in cause of tooth loss, supra-erupted tooth type, and arch type parameters.

ABSTRACT Objective: The purposes of this investigation were to determine the horizontal distances between the mandibular posterior teeth and the WALA ridge in a sample of Peruvians with normal occlusion and to compare them by tooth type, sex, arch side, and age groups. Methods: 65 dental casts of subjects with normal occlusion were collected. Posterior teeth, except for third molars, were evaluated. The horizontal distances between the occluso-gingival midpoints of the buccal surfaces (FA points) of each tooth and the WALA ridge were measured using a modified digital caliper. The values between each different tooth type within the sample were compared using the ANOVA and Scheffe tests, while comparisons by sex, arch side and age groups, using the Student’s t-test. Results: The mean distances in the sample was 0.96 mm for first premolars, 1.45 mm for second premolars, 2.12 mm for first molars and 2.55 mm for second molars. Statistically significant differences between each of the four tooth types were found. There were no significant differences found between sex, arch side and age groups. Conclusion: The horizontal distances between the mandibular posterior teeth and the WALA ridge increased progressively from the first premolars to the second molars in Peruvians with normal occlusion. The WALA ridge was a good landmark to evaluate the positions of posterior teeth in Peruvians with normal occlusion.

ABSTRACT Background Pulp stones are calcification in the dental pulp which can be present either in deciduous or permanent teeth. Exact causes of pulp stones are not known and several elements have been associated. It can be seen in healthy, diseased or as a part of various syndromes. Frequency of pulp stones fluctuated from 8 to 95% depending on the population studied. Our study is an attempt to know the prevalence of pulp stones in radiographs of South Karnataka population and to assess probable relations between pulp stones and gender, type of tooth, dental arch and quadrant. Comparison of our results with published documents was done and our study statistics can be considered as an added information in the field of forensic dentistry. Materials and methods One thousand panoramic radiographs were retrospectively evaluated which included 576 females 424 males aged between 18 and 70 years. A total of 27,184 teeth were examined for the presence of pulp stones. Associations of pulp stones with sex, tooth type, dental arch and side were noted. Results Pulp stones prevalence was 7.5% of subjects. Out of 27,184 teeth examined, 394 teeth revealed pulp stones (1.45%). Occurrences were rare in premolars (2%) but significantly higher in molars (54.6%). Pulp stones were seen more in first molars than second molars and in maxillary first molars than in mandibular first molars. Pulp stones were commonly seen in 26 to 45 years age group. Conclusion Pulp stones may provide useful forensic information when examining dental records to identify deceased persons. Dental features vary among different population and thus knowing the prevalence is significant in the forensic aspect. How to cite this article Sandeepa NC, Ajmal M, Deepika N.

The purpose of this paper is to demonstrate 4 cases with bi-lateral ectopic mandibular canines and to demonstrate in each case which one of the two canines erupted to a normal position in the dental arch. The canines are observed from Orthopantomograms from 4 children (aged 8-13 years of age) in the mixed dentitions stages. Of these children 2 were males and 2 were females. From each child there was between 3-5 Orthopantomograms. These were observed over 3-4 years period. In each of the 4 cases with bi-lateral ectopia of the mandibular canines the one mandibular canine erupted into a normal position, while the other one declined into a horizontal position during the mixed dentition period. These 4 cases demonstrated that the inclination of the canines were important to observe and diagnose from the initial stage (first ortopantomogram). The cases presented, demonstrated that the unsuccessfully erupted canines ending in a horizontal position, were the canines which inclined slightly more that the contra lateral canine already from the initial stage.

The study aimed to assess the number, localization and distribution of interleukin 6 (IL-6) positive cells in healthy pulp, acute and chronic pulpitis. The study group included 48 patients aged between 18-72, treated in University of Medicine and Pharmacy Grigore T. Popa Iasi, Romania. The pulpectomy was performed on 42 patients diagnosed with acute and chronic pulpitis. The other 6 patients, without signs of dental caries or periodontal disease, were submitted to extractions of teeth for orthodontic purposes, with pulpectomy performed before extraction. The pulp samples were examined with optic microscope. The detection and assessment of IL-6 were performed using immunohistochemical technique. Data were statistically analysed using non-parametric tests. According to morphopathological criteria, 42.85% were classified as acute pulpitis and 57.14% as chronic pulpitis. The pulp samples in control group were not associated with IL-6 positive cells. The analysis of all samples with acute and chronic pulpitis identified 73.80% samples with IL-6 and 26.20% associated with the absence of IL-6. The highest frequency of IL-6 positive cells was recorded in rich-cell zone of crown dental pulp. The systemic distribution of IL-6 positive cells was mostly diffused without well-defined orientation. IL-6 release in acute and chronic pulpitis is significantly higher comparing with healthy pulp tissue.

Obiectives: To report our experience of diagnosis and multimodal management of urolithiasis in renal transplantation. Patients and Methods: From January 1995 to December 2012, 953 patients underwent renal transplantation in the Kidney Transplant Unit of Treviso General Hospital. Ten (10%) of them developed urinary calculi and were referred at our institution. Their mode of presentation, investigation and treatment were recorded. Results: Seven had renal and 3 ureteral calculi. Urolithiasis was incidentally discovered on routine ultrasound in 6 patients, 1 presented with oliguria, 1 with anuria and acute renal failure and in 2 urolithiasis was found at removal of the ureteral stent. Nephrostomy tube was placed in 5 patients. Hypercalcemia with hyperparathyroidism (HPT) was present in 5 patients and hyperuricemia in 3. Two patients were primary treated by shock wave lithotripsy (SWL) and one of them was stone-free after two sessions. Two patients, one with multiple pielocaliceal calculi and the other with staghorn calculus in the lower calyx, were treated with percutaneous nephrolitothotomy (PCNL). Three patients were treated by ureteroscopy (URS) and in one of them two treatments were carried out. One patient had calculus impacted in the uretero-vesical anastomosis and surgical ureterolithotomy with re-do ureterocystoneostomy was performed after failure of URS. Two patients with calculi discovered at removal of the ureteral stent were treated by URS. Conclusions: The incidence of urolithiasis in renal transplantation is uncommon. In the most of patients the condition occurs without pain. Metabolic anomalies and medical treatment after renal transplantation may cause stone formation. Advancements in endourology and interventional radiology have influenced the management of urolithiasis that can be actually treated with a minimal incidence of risk for the renal allograft.

Purpose: Radiographic abnormalities in the pubic bone and symphysis are often seen in athletes with groin pain. The aim was to create a grading scale of such radiologic changes. Material and Methods: Plain radiography of the pelvic ring including the pubic bone and the symphysis was performed in 20 male athletes, age 19–35, with long-standing uni- or bilateral groin pain. We used two control groups: Control group 1: 20 healthy age-matched men who had undergone radiologic examination of the pelvis due to trauma. Control group 2: 120 adults (66 men and 54 women) in 9 age groups between 15 and 90 years of age. These examinations were also evaluated for interobserver variance. Results and Conclusion: The grading scale was based on the type and the amount of the different changes, which were classified as follows: No bone changes (grade 0), slight bone changes (grade 1), intermediate changes (grade 2), and advanced changes (grade 3). The grading scale is easy to interpret and an otherwise troublesome communication between the radiologist and the physician was avoided. There was a high interobserver agreement with a high kappa value (0.8707). Male athletes with long-standing groin pain had abnormal bone changes in the symphysis significantly more frequently and more severely ( p>0.001) than their age-matched references. In asymptomatic individuals such abnormalities increased in frequency with age both in men and women.

ABSTRACTTwo groups of 3-year-old children (3:0–3;6 and 3;6–4;0) observed two actions of a toy. In one condition an older partner was absent while the subject watched both of the toy actions (fully ignorant partner), whereas in the other condition the partner witnessed one of the two actions together with the subject (partially ignorant partner). When asked about the toy's actions by their partially ignorant partner both age groups adjusted their answers to their partner's ignorance and mentioned only that action which was new to their partner. However, in their answers to their fully ignorant partner the younger children tended to provide insufficient information by mentioning only one instead of both actions.

Sjögren‘S Syndrome

Background:Primary Sjogren’s Syndrome (PSS) is an autoimmune and lymphoproliferative disease with a heterogeneous presentation. It has been postulated that there may be different phenotypes, in some cases presenting a more aggressive disease with systemic manifestations and a higher risk of developing complications. This phenotype has been associated with a higher autoimmune load and an earlier age of presentation. Furthermore, the presence of anti La + has been related to an increased risk of developing Lymphoma.Objectives:To describe the phenotypic characteristics of seronegative PSS in a sample of patients from our practice. To compare the clinical and laboratory characteristics between patients with Ro + / La + and Ro + / La- antibodies. To Analyze if there are differences in patients diagnosed at an early age, compared to a later age.Methods:Clinical and serological characteristics of patients with the diagnosis of PSS were collected from the Rheumatology database of León`s Hospital between 2014-2020. All patients who met the ACR / EULAR 2016 criteria were classified as seronegative Sjogren.In the group of patients with positive autoimmunity, anti-Ro + / La + were compared with the anti-Ro + / La- patients and by age, stratifying them into the following groups: 0-49; 50-69 and> 70 years. The clinical variables analyzed were: glandular inflammation, Raynaud’s phenomenon (RP), pulmonary and neurological involvement, presence of Lymphoma and other tumours. The serological variables were: positivity of ANA, Rheumatoid Factor (RF), hypocomplementemia, hypergammaglobulinemia and B2 microglobulin.Results:72 patients were analysed, 9 were excluded because didn’t meet the criteria. Of the remaining: 90,4% were women, with a mean age of 58,7+/-15,8 years, 12,6% (8) were seronegative. In the seronegative group 25% presented lung involvement (Lymphoid Interstitial Pneumonia), 50% presented with glandular inflammation and only one patient had RP. As complications 1 patient presented Lymphoma and 1 Breast Carcinoma.58,7% (37) Ro + / La + and 28,5% (18) Ro + / La- patients were identified, no statistically significant differences were found between the two groups when comparing: glandular inflammation (8/37 vs 2/18, p = >0.05) RP (9/37 vs 4/18, p = >0.05), pulmonary involvement (5/37 vs. 6/18, p = >0.05), neurological involvement (2/37 vs. 1/18, p = >0.05), presence of Lymphoma (2/37 vs. 0 / 18, p = >0,05), other tumours (2/37 vs 3/18, p = >0.05), ANA positivity (36/37 vs 16/18, p =>0,05), Hypocomplementemia (4/37 vs 3/18, p =>0.05) and Hypergammaglobulinemia (20/37 vs 10/18, p =>0.05). But a higher frequency of positive RF linked to anti La positivity (29/37 vs 6 / 18p = 0.002) was found.When comparing by age groups, the association between RF + and La + remained in the group of 50-69 years (15/18 vs 3/18, p = 0.002) while in the other age groups there were no statistically significant differences. We also observed an increasing trend of the levels of B2microglobulin in La+ patients and later age (p=0,04)Conclusion:The presence of anti La + seems to be associated with other components of autoimmunity such as RF in patients with PSS, although this study did not show a relation with a higher frequency of complications or systemic disease. Also, the presence of La+ at older ages was associated with higher levels of B2 microglobulin. We didn’t find differences with the other described markers of B cell reactivation. Findings differ from those found in the literature, which may be largely due to sample size.References:[1]Quartuccio L., Baldini C., Bartoloni E., et al.

Abstract Background The Philippines has been one of the most affected COVID-19 countries in the Western Pacific region, but there are limited data on COVID-19-related mortality and associated factors from this setting. We aimed to describe the epidemiological and clinical characteristics and associations with mortality among COVID-19-confirmed individuals admitted to an infectious diseases referral hospital in Metro Manila. Main text This was a single-centre retrospective analysis including the first 500 laboratory-confirmed COVID-19 individuals admitted to San Lazaro Hospital, Metro Manila, Philippines, from January to October 2020. We extracted clinical data and examined epidemiological and clinical characteristics and factors associated with in-hospital mortality. Of the 500 individuals, 133 (26.6%) were healthcare workers (HCW) and 367 (73.4%) were non-HCW, with HCW more likely presenting with milder symptoms. Non-HCW admissions were more likely to have at least one underlying disease (51.6% vs. 40.0%; p = 0.002), with hypertension (35.4%), diabetes (17.4%), and tuberculosis (8.2%) being the most common. Sixty-one (12.2%) died, comprising 1 HCW and 60 non-HCW (0.7% vs. 16.3%; p < 0.001). Among the non-HCW, no death occurred for the 0–10 years age group, but deaths were recorded across all other age groups. Compared to those who recovered, individuals who died were more likely to be older (p < 0.001), male (p = 0.015), report difficulty of breathing (p < 0.001), be HIV positive (p = 0.008), be intubated (p < 0.001), categorised as severe or critical (p < 0.001), have a shorter mean hospital stay (p < 0.001), or have an additional diagnosis of pneumonia (p < 0.001) or ARDS (p < 0.001). Conclusion Our analysis reflected significant differences in characteristics, symptomatology, and outcomes between healthcare and non-healthcare workers. Despite the unique mix of cohorts, our results support the country’s national guideline on COVID-19 vaccination which prioritises healthcare workers, the elderly, and people with comorbidities and immunodeficiency states.
