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.

Introduction: Zygomatico-orbital fractures are the second most common facial injuries. Trauma to mid-facial region can lead to an alteration or loss of sensation in the facial region which sometimes requires early surgical intervention to aid in an early recovery. Aim: To evaluate the different neurosensory changes in the infraorbital nerve function following common treatment modalities used in the management of zygomatico-maxillary complex fractures. Materials and Methods: Thirteen patients selected for the study had unilateral zygomatic complex fracture with altered sensation in the region of distribution of the infraorbital nerve. The fractures were managed either by reduction followed by internal fixation with mini-plates (Group A), reduction alone (Group B) or conservatively (Group C). Infraorbital nerve function tests were done by mechanical, heat and pain threshold detection. Evaluation was done on 1st, 3rd, 7th day, one month, three months and six months interval in a manner similar to that done at the beginning of the study (Day0). Results: A male predominance with male:female ratio of 5.5:1 and an age range of 21 to 50 years was found with the right side mostly affected. Road traffic accident was the most common aetiology. Most common clinical presentations were sub-conjunctival haemorrhage (84.61%), flattening of the malar prominence (69.23%) with deficit in neurosensory function of infra orbital nerve. Recovery in the infraorbital nerve function was relatively complete in 76.92% cases with partial recovery in 23.07% of the patients. Conclusion: Marked improvement in the neurosensory function of the infraorbital nerve was found when some form of treatment either in the form of Open Reduction and Internal Fixation (ORIF) or approach through Gillie’s temporal or Keen’s intraoral approach were applied as compared to when conservative treatment was provided. In zygomatic complex fractures, any form of treatment employed brought about decompression of the infraorbital nerve which aided in the recovery of the nerve within a span of 1-6 months, except when no treatment was applied. © 2015, Journal of Clinical and Diagnostic Research.

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.

Hosts immune response elicits cytokines in response to bacterial challenge. We explore role of one such cytokine interleukin-18 (IL-18) in periodontal health and disease.IL-18 is a pro-inflammatory and tumor suppressive cytokine. Dental literatures suggest that IL-18 might have a role to play in the progression from oral health to periodontal disease. Therefore, this study was undertaken to elucidate the level and role of IL-18 in the gingival crevicular fluid (GCF) and serum of individuals with healthy gingiva, chronic gingivitis, chronic periodontitis, and aggressive periodontitis before and after periodontal therapy.Eighty individuals chosen for the study were divided into healthy control group (1A), chronic gingivitis (2A), chronic periodontitis (3A), and aggressive periodontitis (4A) with twenty individuals each. Criteria for the division were the subjects gingival index, probing pocket depth, clinical attachment loss, and radiographic evidence of bone loss.The individuals underwent treatment (scaling in case of Groups 1A and 2A and scaling and root planing followed by flap surgery in Groups 3A and 4A) to form posttreatment Groups 1B, 2B, 3B, and 4B, respectively. Thus, a total of 160 GCF and 160 serum samples were collected and tested by ELISA.Intergroup comparison was done by post hoc Tukeys test.The mean IL-18 concentration was greatest in Group 3A (GCF 144.61 pg/l, serum 55.12 pg/ml) followed by Group 4A (GCF 98.55 pg/l, serum 39.06 pg/ml), Group 2A (GCF 22.27 pg/l, serum 27.73 pg/ml) and lowest (GCF 17.94 pg/l, serum 11.49 pg/ml) in Group 1A. Posttreatment groups (1B-4B) showed reduction in the mean IL-18 concentration in both GCF and serum.As the inflammation increased, there was a concomitant increase in the level of IL-18 and vice versa following periodontal therapy.

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.

Background: Enamel hypoplasia is a unique lesion showing wide variations in prevalence among populations. The present study aimed to evaluate frequency and degree of expression of enamel hypoplasia of primary canine in populations living in the eastern part of India. Materials and Methods: A prospective cross sectional study was performed in randomly selected 3539 school children. Labial surfaces of all primary canines were examined. The frequency and degree of expression of enamel hypoplasia between different ethnic groups were recorded. Based on the location of the defect on the tooth surfaces, the lesions were divided as prenatal, perinatal, and postnatal according to stage of mineralization. Statistical analysis was carried out using Chi square test. Results: The overall prevalence of primary canine hypoplasia was 10.3%. The mandibular primary canines were significantly (P = 0.03) more frequently affected than maxillary canines among different ethnic groups. The side difference among populations was not significant (P = 0.96) statistically. In 8.5% Bengali population, 7% Rajbangsi population, and 9.4% in other group of population, the defect occurred prenatally. Most of the defects, 64.7% in Bengali, 66.1% in Rajbangsi, and 58.8% in others occurred during perinatal stage of mineralization. The defect occurred postnatally in 26.8%, 26.7%, and 31.8% in Bengali, Rajbangsi, and in other group of population respectively. Conclusion: The overall prevalence of primary canine hypoplasia was 10.3%. The mandibular primary canines were more frequently affected (P = 0.03) than their maxillary counterparts among populations. Most of the defects correspond to perinatal stage of mineralization.

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.
