RESUMO
This case report describes a case of intention replantation in a 15-year-old patient with a mandibular permanent right second molar that had undergone root canal treatment previously. The tooth was tender on percussion. Radiographic evaluation showed the presence of a separated instrument and periapical radiolucency. The surgical procedure was performed under local anesthesia, and the tooth was extracted. After cleaning and disinfecting the root canal system, the tooth was reimplanted, and the socket was filled with a mixture of bone graft material and a growth factor. A stainless steel crown was then placed to protect the tooth. A follow-up examination was performed after 12 months. The clinical and radiographic examinations revealed a well-healing periapical lesion with no signs of infection. The patient was asymptomatic, and the tooth was functional. The results of this case indicate that intentional replantation can lead to a favorable outcome.
RESUMO
The aim was to establish a specific and definite connection between non-syndromic orofacial cleft patients and associated congenital heart disease (CHD). Following PRISMA guidelines, selective databases were searched for data collection. Studies showing a definite association of CHD with orofacial cleft were included, and studies non-specific of the association of orofacial cleft with CHD were excluded. Data extraction criteria were study design, frequency of CHD in overall non-syndromic orofacial cleft and in specific cleft type, and most prevalent congenital cardiac anomaly. DerSimonian Laird random effects model was used to estimate the pooled proportion of CHD, along with corresponding 95% confidence intervals (CIs) for each measure. Publication bias was assessed using Fail-Safe N analysis and the Rosenthel approach. Of a total of 182 articles searched, only 30 studies were assessed. The overall pooled estimate of the proportion of CHD in total cleft lips/palates was 16% (95% CI: 13-19). The odds of developing CHD in cleft palates was 4.08 times more as compared to cleft lips with 95% CIs of 3.86-4.33, and 1.65 more as compared to cleft lips and palates both with 95% CI of 1.52-1.68. We affirm the upsurging prevalence of CHD in non-syndromic cleft children and vehemently propose that it is of utmost importance to inculcate it in practice and policy-making to screen all non-syndromic orofacial cleft children for congenital cardiac anomaly. This study was registered on PROSPERO (ID no. CRD42023391597) on February 24, 2023.

Rationale: Odontomas result from abnormal growth of differentiated epithelial and mesenchymal cells, which form ameloblasts and odontoblasts along with pulp tissue at times. Patient Concerns: A patient reported with a chief complaint of hard swelling of the lower jaw causing difficulty in mouth opening and facial deformity. Diagnosis: A provisional diagnosis of complex odontome based on clinicoradiological findings was made, which was later confirmed as complex composite odontome histologically. Treatment: Bilateral hard tissue mass was surgically removed from the mandible with utmost precaution to prevent jaw deformity. On fine separation, the specimen yielded nearly 82 small teeth-like structures. Outcomes: Histopathologically, multiple small teeth-like structures with haphazardly arranged central fibrofatty pulpal stroma surrounded by well-formed dentinal tubules and empty areas representing decalcified enamel matrix surrounded by fibrovascular stroma at the periphery were seen. Take-away Lessons: Early diagnosis and treatment ensures minimal surrounding deformities, better prognosis, and less chances of recurrence.
RESUMO
Background and Aim: Mucormycosis is a potentially lethal but rare fungal infection that is rapidly progressive. Rhino-orbito-cerebral mucormycosis (ROCM) was the predominant presentation of COVID-19-associated mucormycosis (CAM). Hence, the present study aimed to assess the oral manifestations in CAM patients admitted to the Indira Gandhi Institute of Medical Sciences-A Tertiary Health Care Center. Materials and Methods: This study was conducted on hospitalized patients admitted to our tertiary health care center during the second wave of the COVID-19 pandemic. A total of 54 patients were included in the study and were further evaluated for oral manifestations. Detailed history, clinical examination, and surgical exploration was done for all the subjects. All cases were confirmed by MRI and histopathology. Results: Data collected was subjected to descriptive and inferential statistical analyses. Patients with oral manifestations were mostly in the age range of ≤50 years which was 56.7% (n = 17). Male patients 56.7% were affected more as compared to female patients and most of the patients in our study were from rural areas 56.7%. RBS [Mean ± standard deviation (SD)] was 304.60 ± 100.073. On intra-oral examination 96.7% had a gingival and palatal abscess, 63.3% had tooth mobility, and palatal ulcer/perforation was seen among 56.7% of the patients. Conclusion: The second wave of the COVID-19 pandemic had also created an alarming situation in India and worldwide. Mucormycosis had come as a sudden storm which has created an emergency situation in our hospital and for dental practitioners also. This was also an alarming situation for a dental practitioner for evaluating early signs and symptoms, especially in high-risk patients and decreasing mortality.
RESUMO
AIMS AND OBJECTIVES: This study aimed to compare the vitamin D levels between chronic obstructive pulmonary disease (COPD) patients and healthy controls and to describe the correlation between vitamin D levels and lung functions. METHODS: Fifty COPD patients (cases) and 30 healthy volunteers (controls) were recruited and their serum vitamin D level was measured together with lung function (forced vital capacity and forced expiratory volume in 1 s [FEV1]) by spirometry. vitamin D was categorized as ≤20 nmol/l: deficient, 21-50 nmol/l: inadequate, and ≥51 nmol/l as sufficient. RESULTS: In this case-control cross-sectional study, lower vitamin D levels were associated with lower lung function in both cases as well as controls, the effect being more pronounced in cases. Mean FEV1 at vitamin D ≤20 nmol/l (0.98 ± 0.40 vs. controls 1.93 ± 0.24 with P = 0.006), mean FEV1 at vitamin D 21-50 nmol/l (1.55 ± 0.54 vs. 2.20 ± 0.31 with P = 0.000), and mean FEV1 at vitamin D ≥51 nmol/l (2.06 ± 0.54 vs. 2.20 ± 0.31 with P = 0.002). Moreover, the severity of predicted postbronchodilator FEV1% was also much lower among COPD cohort versus healthy volunteers (mean FEV1%: cases 47.88 ± 14.22 vs. controls 58.76 ± 15.05 with P = 0.002). CONCLUSIONS: Importantly, lung function in both the groups was affected by decreased vitamin D level; decrease in FEV1 was more pronounced among COPD patients compared to controls showing more expiratory airflow limitation. Vitamin D levels are associated with changes in lung function in cases of COPD as well as healthy controls. Larger studies to confirm the association in Indian context are required and routine assessment of vitamin D may be undertaken to obviate the effects of low vitmain D level on lung function.
RESUMO
The GRIN2B (glutamate receptor, ionotropic, N-methyl-d-aspartate 2B) gene, located in the short arm of chromosome 12, encoding the NR2B subunit of the N-methyl-D-aspartate receptor, has recently been recognized to play an important role in corticogenesis and brain plasticity. Deletions in the short arm of chromosome 12 are rare. Hemizygous loss of function of the GRIN2B gene results in developmental delay, whereas gain of function leads to epilepsy, and infantile spasms in particular. In addition, GRIN2B variants have been associated with autism spectrum disorder and schizophrenia. Here the authors report a child with global developmental delay, autistic behavioural features, central hypotonia, dysmorphic features and isolated congenital anomalies of the fingers and toes, and a de novo heterozygous deletion in chromosome locus 12p13.2-p13.1, involving loss of several genes, including GRIN2B. This report and our review of the literature help clarify the distinct phenotypes associated with loss or gain of GRIN2B function.
RESUMO
INTRODUCTION: The main objective of a root canal sealer is to provide a fluid tight seal. The purpose of this systematic meta-analysis was to determine the relative toxicity of commonly used root canal sealers like zinc oxide eugenol, calcium hydroxide, and resin-based sealers. MATERIALS AND METHODS: An online search was conducted in peer-reviewed journals listed in PubMed, Cochrane, EBSCO, and IndMed databases between 2000 and 2012). Statistical analysis was carried out by using analysis of variance (ANOVA) followed by post-hoc comparison by Bonferroni method. The comparison between toxicity at 24 h and between 3 and 7 days was done by using paired t-test for each sealer. RESULTS: At 24 h, the relative biotoxicity of the three sealers reported was insignificant (P- value 0.29), but the difference in toxicity was found significant (P < 0.001) after 3 days. CONCLUSION: Calcium hydroxide sealer and zinc oxide eugenol were found to be significantly biotoxic as compared to resin-based sealers after 3 days.
RESUMO
INTRODUCTION: This study was designed as a clinical trial to evaluate and compare the regenerative potential of platelet-rich fibrin (PRF), platelet-rich plasma (PRP), and blood clot in immature necrotic permanent teeth with or without associated apical periodontitis. METHODS: Access preparation was done under rubber dam isolation. Copious irrigation was done with 2.5% NaOCl and triple antibiotic paste was placed as an intracanal medicament. After 4 weeks, the cases were divided into four groups with five patients in each group. The study design had three test arms and one control arm. Group I in which mineral trioxide aggregate apexification was carried out and it was kept as control group to evaluate the regenerative potential of blood clot and platelet concentrates, Group II in which blood clot was used as scaffold in the canal, Group III in PRF was used as scaffold, and Group IV in which PRP carried on collagen was used as a scaffold. RESULTS: The clinical and radiographic evaluation after 6 and 18 months was done by two independent observers who were blinded from the groups. The scoring was done as: None score was denoted by, Fair by 1, Good by 2, and Excellent by 3. The data were then analyzed statistically by Fisher's exact test using Statistics and Data 11.1(PRP Using harvest Smart PReP2) which showed statistically significant values in Group III as compared to other Groups. CONCLUSION: PRF has huge potential to accelerate the growth characteristics in immature necrotic permanent teeth as compared to PRP and blood clot.
RESUMO
Pyridoxine dependent epilepsy (PDE) is caused by mutations in the ALDH7A1 gene encoding α-aminoadipic semialdehyde dehydrogenase. The classic clinical presentation is neonatal seizures responsive only to pyridoxine therapy. White matter abnormalities, corpus callosum agenesis or hypoplasia, megacisterna magna, cortical dysplasia, neuronal heterotopias, intracerebral hemorrhage, and hydrocephalus in neuroimaging have been reported in patients with PDE. We report a new patient with asymmetric progressive ventriculomegaly noted on fetal sonography at 22 weeks' gestation. Postnatal brain sonography on day 1 and MRI on day 5 confirmed bilateral asymmetric ventriculomegaly caused by bilateral subependymal cysts. Intractable seizures at age 7 days initially responded to phenobarbital. Markedly elevated urinary α-aminoadipic acid semialdehyde levels and compound heterozygous mutations in the ALDH7A1 gene (c.446C>A/c.919C>T) confirmed the diagnosis of PDE caused by ALDH7A1 genetic defect. Despite the presence of structural brain malformations and subependymal cysts, PDE should always be included in the differential diagnosis of neonatal seizures that are refractory to treatment with antiepileptic drugs.

Anti-glutamic acid decarboxylase directed antibodies are a rare cause of autoimmune limbic encephalitis that is relatively resistant to immunotherapy. Here we report a 15-year-old boy with nonparaneoplastic, anti-glutamic acid decarboxylase limbic encephalitis presenting with subacute headache, memory disturbance, psychiatric symptoms, and seizures. At onset, his memory disturbance manifested as transient global amnesia-like episodes. Clinical remission was achieved with rituximab, intravenous immunoglobulin, and corticosteroids.

Contemporary studies have shown that the regeneration of tissues and root elongation is possible in necrotic immature permanent teeth. The purpose of this case report is to add a new vista in regenerative endodontic therapy by using platelet rich fibrin for revitalization of immature non vital tooth. An 11year old boy with the history of trauma was diagnosed with the pulpal necrosis and symptomatic apical periodontitis in tooth #21. Intra oral periapical radiograph showed open apex and associated immature supernumerary tooth with respect to tooth #21. Access preparation and minimal instrumentation was done to remove necrotic debris under copious irrigation with 2.5% sodium hypochlorite. Triple antibiotic paste was packed in the canal for four weeks. During second visit, 5 mL of whole blood was drawn from the medial cubital vein of the patient and blood was then subjected to centrifugation at 2400 rpm for 12 minutes for the preparation of Platelet rich fibrin (PRF) utilizing Choukroun's method. Triple antibiotic paste was removed and canal was dried. PRF clot was pushed to the apical region of tooth #21 using hand pluggers. Three milimetres of Mineral trioxide (MTA) was placed in cervical part of the root canal and permanent restoration was done three days later. Clinical examination at 6 and 12 months revealed no sensitivity to percussion and palpation in tooth #21and it responded positively to both electric pulp and cold tests. Radiographic examination showed resolution of periapical rarefaction, further root development and apical closure of the tooth #21 and its associated supernumerary tooth. On the basis of successful outcome of the present case it can be stated that PRF clot may serve as a scaffold for regeneration of necrotic immature teeth.
RESUMO
UNLABELLED: A 10-year-old boy with transcobalamin II (TCII) deficiency on oral cyanocobalamin therapy presented with acute right hemiparesis and sensory axonal neuropathy in the context of an intercurrent viral illness. MRI demonstrated unilateral globus pallidus stroke with normal MRA. Echocardiogram was normal. Methylmalonic acid in serum was mildly elevated at 10.29 µmol/L (normal < 0.37 µmol/L), which was an 18-fold increase from his previous baseline. The patient was switched to IM cyanocobalamin and serum methylmalonic acid levels normalized over 6 months to 0.01 µmol/L. After 4 months of IM cyanocobalamin therapy, the neuropathy had resolved. Repeat MRI 4 months after the sentinel stroke demonstrated a chronic-appearing contralateral globus pallidus stroke of uncertain timing. CONCLUSIONS: We are describing the first case of metabolic stroke and peripheral neuropathy in TCII deficiency. The neuropathy was responsive to parenteral hydroxycobalamin. Unilateral globus pallidus stroke in the appropriate clinical context should not exclude a metabolic etiology as it may herald contralateral involvement and may provide an opportunity for early recognition and treatment. IM hydroxycobalamin should be strongly considered in all patients with TCII, particularly when they reach later childhood. This case highlights the selective vulnerability of the globus pallidus to increased levels of methylmalonic acid of various causes, which is important for both diagnosis and ultimately understanding the mechanisms of neurological injury in this group of conditions. Metabolic stroke may occur with lower levels of methylmalonic acid than previously reported in the context of an intercurrent bioenergetic stressor.
RESUMO
We present a case of a female child who had developed progressive skin tightening of whole body, sclerodactyly, and severe contracture of all joints with restricted opening of mouth with disease onset at 6 weeks of life. The child also had anemia, failure to thrive, recurrent diarrhea, and ascites. Skin biopsy revealed characteristic histopathological features suggestive of scleroderma. Echocardiography revealed thrombus in the right atrium extending to inferior vena cava. Serological markers (antinuclear antibody, antiscl 70, anti-double-stranded DNA, anticentromere antibody) were negative. To our knowledge, this case of scleroderma with disease onset at 6 weeks of life could possibly be among youngest cases reported in the literature. Also, thrombosis in inferior vena cava in a child with scleroderma is being reported for the first time.
