Fishing is an occupation associated with uneven diet, strain, drunkenness, tobacco use, and deleterious habits. The physical state of laborers on a large scale will also be influenced by conditions at their work site. Oral mucosal lesions can occur as a result of infections, local shock or infuriation, systemic diseases, and uncontrolled usage of tobacco, betel quid, and alcohol. The aim of the present study is to assess the prevalence of deleterious oral habits and oral mucosal lesions among fishermen population of Mahe, South India.The study population consists of 362 fishermen aged between 15 and 54. The questionnaire consisted of questions on personal data, and information related to the subjects oral habits were collected by the interview. The World Health Organization (WHO) Oral Health Assessment Form was designed for the assessment of oral mucosal lesions.Among the 362 fishermen, 266 (73.48%) were males and 96 (26.52%) were females. The overall prevalence of smoking, alcohol consumption, and gutka chewing was found to be 24.3, 48.85, and 32.4% respectively. Smokeless tobacco (32.4%) was the most prevalent habit followed by smoking tobacco (24.3%). The prevalence of oral mucosal lesions was 14.9%. There is a statistically significant association between age groups and habits considered.Findings of the present study suggest that oral health condition of the fisherfolk community was relatively poor, with high habit prevalence and oral mucosal lesions. This epi-demiological study has provided baseline data to plan further research in this area.Low socioeconomic status, strenuous working hours, inadequate diet and nutrition intake, stress, and use of tobacco and alcohol act as contributing factors for ill health and oral diseases. It is a challenging population to the clinician to identify and treat them.

To assess speech outcomes after anterior maxillary distraction (AMD) in patients with cleft-related maxillary hypoplasia.Fifty-eight patients at least 10years old with cleft-related maxillary hypoplasia were included in this study irrespective of gender, type of cleft lip and palate, and amount of required advancement. AMD was carried out in all patients using a tooth-borne palatal distractor by a single oral and maxillofacial surgeon. Perceptual speech assessment was performed by 2 speech language pathologists preoperatively, before placement of the distractor device, and 6months postoperatively using the scoring system of Perkins etal (Plast Reconstr Surg 116:72, 2005); the system evaluates velopharyngeal insufficiency (VPI), resonance, nasal air emission, articulation errors, and intelligibility. The data obtained were tabulated and subjected to statistical analysis using Wilcoxon signed rank test. A P value less than .05was considered significant.Eight patients were lost to follow-up. At 6-month follow-up, improvements of 62% (n= 31), 64% (n= 32), 50% (n= 25), 68% (n= 34), and 70% (n= 35) in VPI, resonance, nasal air emission, articulation, and intelligibility, respectively, were observed, with worsening of all parameters in 1 patient (2%). The results for all tested parameters were highly significant (P .001).AMD offers a substantial improvement in speech for all 5 parameters of perceptual speech assessment.

To evaluate the results of anterior maxillary distraction for its efficacy and long-term stability in the management of cleft maxillary hypoplasia in a large series of patients with a long-term follow-up extending to 4years.One hundred sixty-four patients at least 10years old with cleft maxillary hypoplasia who presented to the authors unit from January 2009 through October 2014 were evaluated retrospectively, irrespective of gender, type of cleft lip and palate, and amount of advancement needed. Anterior maxillary distraction using a tooth-borne distractor appliance was carried out in all patients and all patients were followed up to 4years (range, 1 to 4yr) to evaluate the stability of the procedure and to document any relapse using digitalized lateral cephalograms taken before distraction, immediately after distraction (T2), and at the last follow-up visit (T3; range, 1 to 4yr). Seventeen patients were subsequently lost to follow-up; therefore, a complete set of records was available for 147 patients. In a subset of 50 patients, perceptual speech assessment was carried out preoperatively and 6months postoperatively by 2 speech pathologists using the Perkins scoring system that allowed the evaluation of 5 parameters (velopharyngeal insufficiency, resonance, nasal air emission, articulation, and intelligibility). None of these patients underwent speech therapy during the course of evaluation. The development of complications intra- or postoperatively was noted. The data were tabulated and analyzed.An advancement ranging from 4.0 to 13.1mm (mean, 9.42mm) was achieved in all patients. One hundred forty patients (95.23%) showed stable results on lateral cephalograms and when T2 values were compared with T3 values. Seven patients (4.76%) exhibited skeletal relapse in various linear and angular measurements assessed on lateral cephalograms. At 6-month follow-up, improvements of 62% (n= 31), 64% (n= 32), 50% (n= 25), 68% (n= 34), and 70% (n= 35) in velopharyngeal insufficiency, resonance, nasal air emission, articulation, and intelligibility, respectively, were observed, with worsening of all parameters in 1 patient (2%). An overall complication rate of 25.17% (n= 37) was noted, with bleeding being the most common intra- and postoperative complication noted in 15 patients (10.2%). No serious consequences related to any complication were noted.Anterior maxillary distraction can be considered a suitable treatment option for the management of mild to moderate cleft maxillary hypoplasia because the anteroposterior deficiency can be addressed at a young age, immediately after the eruption of the maxillary second premolars. Stable long-term results with negligible skeletal relapse are possible with this technique, with an added advantage of unhampered or even improved velopharyngeal function.

When restoring an endodontically treated tooth with deficient coronal tooth structure, posts can be used to strengthen the tooth. Recently prefabricated posts are widely used as they exclude the need for complex laboratory procedures making the procedure time saving. But the post-placement can produce stresses that cause root fracture. Different techniques can be used to study the stress distribution due to different posts, but most of them are two-dimensional and difficult to reproduce.The aim of the study was to compare the stress distribution in a maxillary central incisor with Titanium and Glass fiber posts with and without ferrule using the three dimensional finite element analysis.In this study 3D finite element analysis was used. Four models P1(Endodontically treated maxillary central incisor with a ferrule of coronal dentin and restored with parallel sided prefabricated titanium post and composite resin core), P2 (Endodontically treated maxillary central incisor restored with parallel sided prefabricated Titanium post and composite resin core without a ferrule of coronal dentin), P3 (Endodontically treated maxillary central incisor with a ferrule of coronal dentin and restored with parallel sided prefabricated glass fiber reinforced composite post and composite core), P4 (Endodontically treated maxillary central incisor restored with parallel sided prefabricated glass fiber reinforced composite post and composite core without a ferrule of coronal dentin), were modeled using PRO E software. Then stress analysis was done using ANSYS WORKBENCH 10.0software. A load of 100 N was applied to the models at 2mm from the incisal edge on the palatal surface with an angle of 45The results suggested that maximum stresses were seen around posts in order of Titanium post without ferrule followed by Titanium post with ferrule next Glass fiber post without ferrule followed by Glass fiber post with ferrule.Stress distribution in a maxillary central incisor restored with titanium post is greater than when restored with glass fiber post. Stress distribution around posts is greater when a ferrule is not present.

A review in affected persons attitude in abstract care of edentulous patients has to be a priority in elderly individuals. The development of complete dentures (CDs) has been the selection of remedy retaining in mind the socioeconomic popularity, age, and nutritional elements. However, most of the patients complain of loss of retention in mandibular implant-supported overdentures (ODs), which compensated the downside of the loss of retention in complete dentures (CDs). Moreover, implant supported over dentures (ISOVDs) supplied accurate exceptional of lifestyles, esthetics, progressed nutritional deficiencies, and provided good patient satisfaction. The place of dental implants and desire of retentive attachments for implant supported mandibular over dentures (ISOVD) are selected on clinician preference and professional opinion. This text offers a fundamental statistics regarding implant placement, mode of treatment to be selected, and patient care. Two implants provide extraordinary long-term achievement and survival with improved oral capabilities. Single midline implant OD is costly, powerful, and may be a promising alternative. In maxilla, 4-6 implants splinted with bar have located to give true results.

Platelet-rich fibrin (PRF) is a fibrin meshwork, in which platelet cytokines, growth factors, and cells are entrapped and discharged after a period and can serve as a resorbable film. PRF is the next generation of platelet concentrates equipped to improve arrangement without biochemical blood handling; PRF is an evolution of the fibrin adhesive, which is widely used in the oral surgery. The guidelines of this innovation depend on concentrating platelets and growth factors in a plasma medium, and initiating them in a fibrin gel, keeping in mind the end goal to enhance the healing of wounds. Maxillary bone loss requires numerous regenerative techniques: as a supplement to the procedures of tissue regeneration, a platelet concentrate called PRF was tested for the 1

After the introduction of the multidrug therapy, the incidence of leprosy is decreasing every year. However, periodontal complaints are commonly seen in these patients due to compromised immunity and impaired oral hygiene. The aim of the present study is to assess the oral and periodontal status of the leprosy patients in Dindigul district.The study was conducted on 62 patients treated in a leprosy center at Dindigul district. Among these, 22 (35.5%) were female patients and 40 were male patients (64.5%). Age ranges between 40 and 70 with the mean age being 52. Facial changes, periodontal status, dental caries, attrition, tooth loss, plaque index (Silness and Loe), and calculus component of oral hygiene index-simplified were assessed.Majority of the patients presented with loss of eyebrows and eyelashes, saddle nose, ocular involvement, and leonine facies. Gingival recession (54.8%) was a predominant finding followed by tooth loss (69.5%), mobility (60.86%), attrition (56%), chronic pulpitis (34.7%), and dental caries (26%). Most of the patients had severe periodontitis.Compromised immunity and altered autonomy pave way for many dental complaints such as periodontitis and deposits in tooth with poor oral hygiene. Awareness about the oral health problems and reinforcement of oral hygiene should be insisted to the leprosy patients to prevent further morbidity.

Oral squamous cell carcinoma (OSCC) is the sixth most common malignancy and is a major cause of cancer morbidity and mortality worldwide. Every year, approximately 500,000 new cases of oral and pharyngeal cancers are diagnosed worldwide, and a majority of these cases are seen in developing countries. OSCC arises as a result of multiple molecular events that develop from the combined influences of an individuals genetic predisposition and exposure to environmental carcinogens. Here, we discuss the course of immunological development involving OSCC. We have reviewed a literature available in Medline and Google databases. We draw attention to possible shortcomings and issues requiring clarification. Emphasis is given to precise immunology involving the OSCC. In this article, we try to approach the immunology of OSCC through a practical approach consideration of common difficulties and dilemmas faced by the oral pathologist, and where possible, we offer guidance and practical tips. The article concludes with a brief consideration of the prognostic value of immunology involving the OSCC.

Bone morphogenetic proteins (BMPs) are a group of growth factors also known as cytokines and as metabologens. Originally discovered by their ability to induce the formation of bone and cartilage, BMPs are now considered to constitute a group of pivotal morphogenetic signals, orchestrating tissue architecture throughout the body. The important functioning of BMP signals in physiology is emphasized by the multitude of roles for dysregulated BMP signaling in pathological processes. A study done wherein it was found that protein extracts from bone implanted into the animals at nonbone sites induced the formation of new cartilage and bone tissue. This protein extract contained multiple factors that stimulated bone formation and was termed as BMP. There are at least 15 different BMPs identified to date and are a part of the transforming growth factor- super family. The most widely studied BMPs are BMP-2, BMP-3 (osteogenin), BMP-4, and BMP-7 (osteogenic protein-1). Now, any recombination type of morphogenic proteins have been synthesized, for example - recombinant human BMPs.
