Objective: To establish and determine the accuracy of ANN model for the analysis of lip curve change following extraction and non-extraction orthodontic treatment. Methods: Forty adult subjects who required various combinations of premolars extraction and non-extraction for the correction of their malocclusion were chosen. Based on the extraction pattern, all the subjects (n=40) were divided equally into an extraction and a non-extraction group. The effect of extraction and non-extraction treatment on the depth of upper and lower lip curvature was measured on the lateral cephalograms recorded in natural head position. The data obtained from the cephalometric analysis were used to produce a trained ANN model and then the model was analyzed to determine its accuracy in the prediction of upper and lower lip curvature change. Results: The mean change in the depth of upper lip curvature following various combinations of premolars extraction and non-extraction treatment was significantly different (P<0.05). The predicted values of upper and lower lip curvature change by ANN model were very close to the actual regression analysis values. However, the mean error in predicting the change in the upper and lower lip curvature by ANN model analysis was only 29.6% and 7% respectively which was much less as compared to the routine regression analysis. Conclusions: The premolars extraction and non-extraction orthodontic treatment had significant effect on the depth of upper lip curve, and the mean error in predicting the change in lip curvature with ANN analysis was much less as compared to computer based statistical analysis.

Background: Ocimum sanctum is a plant which is of great medicinal value and has various properties for curing and preventing disease.Hence a study was conducted to determine the effectiveness of Ocimum sanctumon bacterial plaque and its comparison with Chlorhexidine gluconate which is considered as the gold standard. Materials and Methods:30 chronic periodontitis patients were randomized into two groups. Group A received scaling and root planing plus intra-pocket irrigation of Ocimum sanctum (n= 15) and Group B received scaling and root planing plus intra-pocket irrigation with Chlorhexidine gluconate (n = 15).Clinical parameters including the plaque index, gingival index, pocket probing depth and clinical attachment level were assessed at baseline and 30 days. Statistical analysis was carried out using SPSS version 17. Statistical significance of P ≤ 0.001 was considered. Results:Our data showed that Ocimum sanctum was equally effective in reducing periodontal indices as chlorhexidine. Significant reduction in all clinical parameters were observed over a period of four weeks in both the test and the control groups. Conclusion:The results of the present study revealed that subgingival irrigation with 4% Ocimum sanctum may prove to be effective owing to its ability in reducing plaque accumulation, gingival inflammation and bleeding andhas no side effects as compared to chlorhexidine.

Aim: The zygomatic bone is the key component of the structural facial aesthetics as it constitutes the prominence of the cheek bone. Also, the most frequent clinical findings in zygomatic arch fracture includes limitation of jaw movement and flattening of cheek. So it is necessary to elevate the arch precisely. Therefore, a prospective study was conducted toevaluate adequacy for reduction of zygomatic arch fracture using Gillie’s temporal approach with the help of pre-operative and post-operative CT scan. Materials & methods: 4patients, who received surgical treatment of zygomatico-maxillary complex (ZMC) fractures at the Department of Oral and Maxillofacial Surgery were examined for displacement of zygomatic arch pre-operatively with CT scan then re-evaluated the same site post-operatively. Results: The pre-operative mean displacement at the zygomatic arch, in millimetres (mm), was M = 2.8, SD = 3.011. After reduction, the post-operative displacement was M = 0.4, SD = 0.699. The percentage of reduction was M = 85, SD = 24.15. Conclusion: Gillie’s temporal approach for zygomatic arch fracture reduction is precisely considerable due to its simple and effective method and cosmetically more acceptable.

Aim: The aim of this study is comparative analysis of post operative analgesic requirement in patient undergoing minor oral surgery using 2% Lignocaine with 1:200000 Adrenaline and Buprenorphine versus 2% lignocaine with 1:200000 Adrenaline. Materials and Method: One hundred patients requiring minor oral surgery were included in the study. The patients were randomized by a third party and allocated to one of the two study groups. This allowed the patients and the operators to remain unaware of the group allocations. 1 ml of Buprenorphine Hydrochloride injection I.V which contains an equivalent of 0.3 mg Buprenorphine was withdrawn into a syringe and injected into a 30 ml vial of 2 % Lignocaine with Adrenaline 1:200000. Thus each ml of local anesthetic contained 0.01 mg of Buprenorphine. This solution was labelled and used for the study. Results: The duration of analgesia in Group I was found to be 13.71 ± 7.2 h and Group II was 39.58 ± the average consumption of NSAIDs was found to be 2.88 as compared to Group II mean valueof 1.29 (P=0.0001). Conclusion: We concluded that addition of 0.3 mg of Buprenorphine to 30 ml Lignocaine with Adrenaline 1:200000 for minor oral surgery results in significant improvement in postoperative analgesia up to 39 h and markedly reduces the need for excessive analgesic intake. Thus reducing the adverse effects associated with excessive use of NSAIDs. Further studies needs to be done as there is less literature about Buprenorphine added to local anaesthetist.

Background: Although implants have shown to have a high success rate, clinicians are also called upon to encounter numerous complications and failures. Among the numerous reasons of failures, peri-implantitis is reported to account for 10% of the failures. As the oral cavity provides a natural habitat for various micro-organism due to its non-shedding surface, there is some evidence that gram-negative anaerobic rods colonize around the implant leading to peri-implanitis. This colonization is dependent on various factors such as the micro-gap at the implant- abutment interface, the precision of fit, degree of micro-movement and applied torque. Aim and Objective: The aim of this article is to provide an overview of current literature on bacterial colonization on the implant surface and the influence of different implant-abutment designs on bacterial colonization. Material and Methods: An electronic search was conducted using the PubMed (Medline),PubMed central and Google scholar to identify articles published on bacterial colonization at the implant-abutment interface. The following search words were used: microbioleakage at implant-abutment interface, surface characteristics/roughness of implants,bacterial adhesion on dental implants, bacterial colonization at implant abutment surface. The articles included in the review comprises of in vitro studies, in vivo studies, review abstracts and review articles. Results: The total number of articles for the key words” microbioleakage at implant-abutment interface” were 29 and for the key words” bacterial colonization at implant abutment interface“ were 17. After considering the inclusive and exclusive criteria, case report, case series and review articles were excluded.11 articles were considered eligible based on their relevance to the subject. Conclusion: Although micro-gap formation inevitably occurs at the implant-abutment interface. The current literature highlights that the formation of this micro-gap is influenced by the type of implant-abutment design used. Though the results are insignificant, recent in vivo and in vitro studies have proved that external hexagon results in higher micro leakage compared to other connections used. Morse-taper connections shows the least amount of microbial leakage.

In the jaws, the most common type of developmental odontogenic cyst is dentigerous cyst, mostly affecting the impacted mandibular third molars and permanent maxillary canines. They are often noted as an incidental finding on radiographs as unilocular radiolucency with well-defined sclerotic border which encircles the crown of an unerupted tooth as most of these dentigerous cysts are clinically asymptomatic. Long standing cases of dentigerous cysts can progress to either ameloblastoma or squamous cell carcinoma or mucoepidermoid carcinoma. Henceforth, an early clinical and radiographic detection of the cyst plays a vital role so that apt treatment modalities can be carried out which will prevent or decrease the morbidity. With this above background, we hereby report an enticing case of dentigerous cyst which was incidentally observed in conventional radiographs and to evaluate further extension and nature of lesion, a conebeam computed tomography (CBCT) of jaw was taken.

Surgical resection of the mandible due to presence of benign or malignant tumor is the most common. Depending upon the location and extent of the tumor in the mandible, various surgical treatment modalities like marginal, segmental, hemi, subtotal, or total mandibulectomy can be performed. Mandibular discontinuity defects present a major challenge to the rehabilitation team and to maxillofacial prosthodontist. Discontinuity of mandible after resection destroys balance and symmetry which leads to altered mandibular movements and deviation of the residual fragment towards the defective side. Variety of materials and techniques have used for the construction of prosthetic replacement of the acquired surgical defects. This case report describes prosthodontic management of a patient who has undergone hemi-mandibulectomy with mandibular guide flange prosthesis. To aid in moving the mandible normally without deviation during functions like speech and mastication.

One of the most common problems encountered by edentulous patients is lack of retention and stability of prosthesis with decreased masticatory efficiency. An over denture treatment is one of the inevitable solutionsfor this condition. This case report highlights the use of an “Access post over denture system” which is more advantageous over the conventional tooth supported over dentures. The access post over denture fabricated was well retentive and esthetic serving as a conservative approach to root preservation.

Introduction: Loss of interdental papilla marks phonetics, functional and esthetic problem. Surgical techniques are diverse, but none have given predictable results. Aim: The purpose of this case report is to present reconstruction of papilla by using platelet rich fibrin membrane in maxillary anterior region. Methodology: 30yr old male patient reported with an unesthetic smile due to loss of interdental papilla in the maxillary left central and lateral incisor region since 6 months. The treatment was planned for reconstruction of lost interdental papilla using PRF. A pouch was created with a semilunar incision, PRF was prepared and inserted into the pouch and the entire gingivopapillary unit was displaced coronally. Conclusion: Optimal fill was noted at 1, 3 and 6 months postoperatively with excellent esthetic outcome.Use of PRF and proper technique may thus be the panacea for interdental papilla augmentation.

The esthetic demands of the patient have to be combined with conservative treatment procedures to deliver functional restorationsfor endodontically treated teeth. Ceramic inlays, fabricated in lithium dislicate material, satisfy both these requirements as post-endodontic restorations. This paper demonstrates a simple, esthetic and conservative alternative to full coverage crowns for the restoration of endodontically treated teeth.
