This paper is a review on Guided Bone Regeneration. Guided Bone Regeneration has emerged as a predictable method to enhance the bone volume in deficient recipient sites prior to implant placement. It provides sufficient bone volume and adequate soft tissue thickness to enable implants to be placed at the most optimal position from a prosthetic point of view. The barrier membrane acts as a physical barrier, excluding competing and non-osteogenic cells from the overlying mucosa into the membrane-protected space.

Introduction: Osteoporotic patients require particular attention to their implant site bone quality as an indication of prognosis and may require modified surgical technique Insertion Torque (IT). Aim: It is the purpose of this study to test whether IT is significantly correlated with bone density or not, as assessed by the cone-beam computed tomography (CBCT) in a group of osteopenic and osteoporotic patients. Materials and methods: A total of 30 patients were included in the study. The mandibular second premolar region was chosen as the site of investigation to prevent variability in surgical implant placement technique in different locations affecting bone mineral density (BMD). Partially, edentulous female patients between 51 and 60 years of age who were scheduled to receive implant placement were recruited for the study. CBCT (Master Series 3D Dental Imaging) was used for preoperative evaluation of the jaws for each patient. Materialise’s Interactive Medical Image Control System (MIMICS) was used to process stacks of 2D images from CBCT. Finite element analysis were carried out on bone using Ansys software. Maximum displacement and maximum stress–strain patterns were compared in normal, osteoporotic, and osteopenic groups. Results: The difference in mean bone density in all three groups were statistically significant (p < 0.05) (Table 1). FEA at 32, 36, 40 N in all 3 groups was statistically significant. (Table 2). Conclusion: Within the limitations of the study, the amount of stress–strain that exhibits at 40 N load in normal bone will be almost the same stress–strain given at 32 N load in osteoporotic bone. Normal IT load analysis exhibits more stress/strain in osteoporotic patients when compared with other groups, showing that IT must be achieved to an optimum level to avoid further complication and failures. © 2017, Jaypee Brothers Medical Publishers (P) Ltd.

Aim: To evaluate the effect of three polishing protocols that could be implemented at recall on the surface roughness of two direct esthetic restorative materials. Materials and Methods: Specimens (n = 40) measuring 8 mm (length) × 5 mm (width) × 4 mm (height) were fabricated in an acrylic mold using two light-cured resin-based materials (microfilled composite and microhybrid composite). After photopolymerization, all specimens were finished and polished with one of three polishing protocols (Enhance, One Gloss, and Sof-Lex polishing systems). The average surface roughness of each treated specimen was determined using 3D optical profilometer. Next all specimens were brushed 60,000 times with nylon bristles at 7200 rpm using crosshead brushing device with equal parts of toothpaste and water used as abrasive medium. The surface roughness of each specimen was measured after brushing followed by repolishing with one of three polishing protocols, and then, the final surface roughness values were determined. Results: The data were analyzed using one-way and two-factor analysis of variance (ANOVA) and Tukey′s honestly significant difference (HSD). Significant difference (P < 0.05) in surface roughness was observed. Simulated brushing following initial polishing procedure significantly roughened the surface of restorative material (P < 0.05). Conclusion: Polishing protocols can be used to restore a smooth surface on esthetic restorative materials following simulated tooth brushing.

Periodontal diseases are a group of chronic infections caused by pathogenic bacteria colonizing the periodontium. Initiation and progression of periodontal infections are affected by local and systemic conditions. The local factors include dental plaque and plaque retentive areas such as dental calculus and defective restorations. Systemic risk factors include poorly controlled diabetes mellitus and tobacco smoking. Systemic conditions associated with immunodeficiency state such as neutropenia, AIDS/HIV infections are also important risk factors. Recent studies have revealed several potentially important periodontal risk indicators. These include stress and coping behaviors and osteopenia associated with estrogen deficiency. There are also demographic factors associated with periodontal disease including gender, and hereditary factors.

To obtain a good occlusion with the correct overjet and overbite. there should be an harmony between the combined mesiodistal widths of maxillary and mandibular teeth. Extraction of premolars is routinely carried out in orthodontic treatment which changes the ratio of inter arch tooth size relationship. Till date Bolton's analysis remains the golden standard for predicting interarch tooth-size discrepancy. 1) To investigate whether the extraction of four premolars as a requirement of orthodontic therapy is a factor in creating tooth size discrepancy. 2) To determine whether any tooth extraction combination creates more severe discrepancies. 3) To investigate the reasons behind such discrepancies if determined due to any extraction combinations. 48 pretreatment models (30 Class I and 18 Class II) with an ideal Bolton's tooth size ratio of 91.3% ± 1 SD were taken and Bolton's analysis -the overall ratio, anterior ratio and Bolton's discrepancy was calculated. Hypothetical tooth extractions were performed with the following combinations. 1) All first premolars, 2) All second premolars, 3) Maxillary first and Mandibular second premolars, 4) Maxillary second and Mandibular first premolars and subjected to Bolton's analysis Mesiodistal dimensions of all premolars were measured and the data is evaluated to find any variation between right and left sides or between the arches. The Maxillary first and Mandibular second premolars extraction group produced the highest discrepancy followed by all first premolars extraction group. The allsecond premolars extraction group produced the least discrepancy.

Oral myiasis is a rare disease caused by larvae of dipteran flies. Houseflies are strongly suspected of transmitting at least 65 diseases to humans, including typhoid fever, dysentery and cholera. Flies regurgitate and excrete wherever they come to rest and thereby mechanically are the root cause for disease organisms. A case of oral myiasis caused by Chrysomya bezziana in the maxillary anterior region in a 40-year-old patient is presented. Manual removal of maggots, and surgical debridement of wound was done followed by broad-spectrum anti-parasitic medications. A note on the identification of the larva and histopathology of the tissue is also highlighted here.

Purpose of the Study: The present study was conducted to evaluate epigenetic alteration of five tumour suppressor genes in the oral precancer and cancer patients.Materials and Methods: The study was carried out in three groups namely control group of five people (normal healthy individuals), 10 oral leukoplakia patients and 10 oral squamous cell carcinoma patients. Incisional biopsy was done and part of the tissue sent for histological examination and part of tissue sent for hypermethylation study of p16, p15, hMLH, MGMT, E-cadherin tumour suppressor genes. Methylation specific polymerase chain reaction was carried out for detecting methylation in promoter regions of tumour suppressor genes. The resultant PCR products were run in a 2.5% Agarose gel and the promoter hypermethylation status of the five tumour suppressor genes were analysed.Results: In oral Leukoplakia patients, 60% of methylation in the case of p16 gene, 30% of methylation in the case of MGMT gene and 60% of methylation in the case of E-cadherin gene. In oral Squamous cell carcinoma patients, 60% of methylation in the case of p16 gene, 40% of methylation in the case of MGMT, 60% of methylation in the case of E-cadherin gene, 20% in case of p15,10% in case of hMLH gene.Conclusion: Our results suggest that epigenetic mechanisms of inactivation of tumour suppressor genes, such as aberrant methylation of p16 and E-cadherin genes occur early in head and neck tumourigenesis and might play a role in the progression of these lesions. © 2014, Journal of Clinical and Diagnostic Research.

The aim of this study was to radiographically investigate the curve existing in slightly curved mesiobuccal canal of mandibular first molar by applying Piecewise straight line approximation. Extracted human mandibular molars were radiographed and one hundred radiographs were selected whose mesiobuccal canal showed slight curvature (10-20°) according to Schneider's method. The curves were traced and analyzed using Piecewise straight line method. Each curve was considered as a unit consisting of six different pieces of straight lines joining at seven specific points and the angle of curvature at these points was determined using the slope formula. All curves analyzed in this study had varying degrees of curvatures at different points on the curve. Maximum curvature (0.40°) was recorded at the middle third of the root canal. Within the limitation of the study, significant curvature occurs through out the curve existing in the mesiobuccal canal of mandibular first molar and the middle third of the curve showing greater degree of curvature. There is a possibility of greater curvature occurring in the coronal third of the curve. Though three dimensional studies would be more appropriate, Piecewise straight line approximation may be a better method than existing methods to simulate canal geometry.

Background: Radiation mucositis is an early effect of head and neck radiotherapy. Mucositis can cause ulcers, and patients may experience pain and dysphagia which need proper management. This study was conducted in 60 patients with oral malignancy. Aim : To evaluate the effect of natural honey and 0.15% benzydamine hydrochloride on onset and severity of radiation mucositis and to compare it with control. Materials and Methods : This study was conducted in the Department of Oral Medicine and Radiology, Tamilnadu Government Dental College and Hospital, Chennai, from April to December 2010. The sample size comprised of 60 patients, of both genders, diagnosed with oral malignancy clinically and histopathologically and planned for radiotherapy. The patients were assigned into three groups by random sampling. Each group consisted of 20 patients. Group 1 patients were instructed for topical application of natural honey, groups 2 and 3 were instructed for topical application of 0.15% benzydamine hydrochloride and 0.9% normal saline respectively. The onset of mucositis and the severity of mucositis were graded during the course of the radiotherapy and two weeks after radiotherapy, with WHO mucositis grading in all the three groups and statistically analysed with SPSS version 11 software. Results: A significant reduction in mucositis in honey-received patients compared with 0.15% benzydamine hydrochloride, 0.9% normal saline applied patients occurred. The differences between the groups were statistically significant (P < 0.001). Conclusion: Pure natural honey can be an effective agent in managing radiation induced oral mucositis. Honey could be a simple, potent and inexpensive agent, which is easily available, and it can be a better therapeutic agent in managing radiation mucositis in developing countries like India for the management of this morbidity.
