Background: Relation between secretory immunoglobulin A (SigA) and dental caries still imprecise. Studies have been conducted either for total SIgA or mutans specific SIgA with bizarre results. Aim: The aim of this study is to find out the relationship between mutans antigen specific SIgA and total salivary SIgA and its influence in caries status in children. Materials and Methods: A total of 45 children aged between 6-14 years were divided based on their caries index (decayed, missing, filled, extracted tooth) score in high moderate and no caries group and their saliva were analyzed with enzyme linked immunosorbent assay for total SIgA and mutans specific SIgA. Results: High caries group showed high mutans specific SIgA, but less total SIgA, whereas low caries group showed the reverse. Conclusion: The mutans specific SIgA and total SIgA has a weak, but negative correlation in children potentiating caries inhibitory action of SIgA. Source

Aim: Well documented cases of oral lichen planus, a cell mediated immune condition is infrequently reported in paediatric population. This study was undertaken to obtain epidemiological data retrospectively and also to explore the possibility of any association that might exist among the clinical and histopathological features in paediatric patients suffering from oral lichen planus. Subjects and Methods: A retrospective study was carried out on 22 patients, younger than 18 years with clinical and histopathological diagnosis of oral lichen planus over a period of 14 years. The clinical characteristics and histopathological features were observed. The statistical analysis of the data was performed using Statistical Analysis Software (SAS), Version 9.1. Results: Analysis of data of 22 patients revealed that the average age of patient is 15.18 years with equal male and female predilection. The most common site is buccal mucosa (50%) and most frequent clinical form is erosive (63.64%). Focusing on the histopathological findings, parakeratosis was found in 86.36% of the cases, acanthosis in 63.64% of cases, moderate basal cell degeneration was identified in 63.64% of cases and dense lymphocytic infiltration at juxtaepithelial connective tissue region was found in 59.09% of cases. Conclusions: Oral lichen planus in paediatric population is rare and appeared between 8 to 18 years of age. There is no significant gender predominance. The most common clinical form is erosive, manifesting mainly in buccal mucosa. Histopathological findings characteristic of oral lichen planus in paediatric patients include parakeratosis, acanthosis, liquefaction degeneration of basal cells and lymphocytic infiltration in the subepithelial layer.

Growing interest of endosseous implant research is focused on surface modification to achieve early and strong osseointegration. The present study compared the behaviour of hydroxyapatite coated, zinc doped hydroxyapatite coated and hydrothermally treated titanium (Ti6Al4V) with machined Ti6Al4V implants (control) on osseointegration. The surface characterization and bacterial affinity test for implants were performed. Forty eight (48) cylinders (4 types in each animal) were placed in the humerus bone of 12 black Bengal goats. Bone-implant interface was examined with histological, radiological parameters and scanning electron microscopy on 42nd, 90th, and 180th day post-implantation. Surface roughness alterations of bone-detached implants with time were analyzed by non-contact profilometer. Push-out test (90th day) was performed to assess the strength of bony integration of implants. The coated implants revealed direct and early bone-implant contact but high bacterial affinity and coating resorption/cracks. Low bacterial affinity and strongest osseointegration was observed with hydrothermally treated implants. Poor bacterial affinity and delayed but strong fixation were evident with control implant. Based on the results of laboratory and animal experiments, we conclude that the hydrothermal modification of titanium implant is the more suitable way to achieve safe and effective osseointegration than the other three implant types for endosseous application. © 2015 Elsevier Ltd.

An immediate surgical obturator is necessary for maxillectomy procedures to minimize functional disabilities in speech, swallowing, and egress of food and liquid into the surgical defect. Sometimes the extent of the tumor may be such that it may even require the removal of the maxillary sinus along with resection of the orbital floor. The resected orbital floor can be surgically reconstructed with autogenous soft and/or hard tissues or with alloplastic materials. This clinical report highlights one such situation where the surgical resection of the maxilla and the orbital floor were rehabilitated with an immediate surgical obturator extending to the orbital floor to support the visual apparatus.

Background: Anomalies in primary dentition are often found to be associated with anomalies in permanent dentition. Aims: This study was performed to evaluate the prevalence of supernumerary teeth, hypodontia, double teeth, and talon cusp in the primary dentition, and their effect on succedaneous permanent teeth. Materials and Methods: In this prospective cross-sectional study, we clinically investigated 2757 Bengali speaking nursery children (1474 girls and 1283 boys), of age four to six years, at their respective schools, and the presence of supernumerary teeth, hypodontia, double teeth, and talon cusp in the primary dentition were recorded. Children with anomalous primary teeth were further subjected to periapical and panoramic radiographic examination, to determine the status of the underlying permanent teeth. Results: The total prevalence of all anomalies in this study was 1.8%. A total of 38 children (21 girls and 17 boys) had anomalies. The prevalence of anomalies was as follows: Supernumerary teeth (0.4%), hypodontia (0.5%), double teeth (0.4%), and talon cusp (0.07%), in both sexes combined. Radiographic examination showed 50% of the patients (19 children) had anomalies in the permanent dentition. Conclusions: Anomalies in primary dentition exhibited a correlation with anomalies in permanent dentition. Source
