A biphasic tumour is a truly histological term that refers to neoplastic tissue which is characterized by two different cellular elements. Several histogenetic theories have been proposed for the aetiogenesis of the biphasic tumours. Literatures have been published on the individual lesions, which have described their biphasic nature but, biphasic tumours have not been categorized singly. Categorizing biphasic tumours is not likely to highlight diagnostic standards, but it may sensitize the therapeutic planning and post operative monitoring. This review article focuses on the histogenetic concepts of biphasic tumours, and the histopathological description of the lesions that are suggested to be biphasic tumours.

The biological process of ageing is outside human control and has its own dynamics. It is a known fact that elderly people have more treatment needs compared to the younger population and at the same time elderly people are facing a multitude of barriers in utilization of health care as well as oral health care.To identify the utilization patterns of oral health care and barriers for utilization among rural population.A cross-sectional study was done on 621 rural elderly subjects to identify the utilization of oral health care services and the barriers for utilization. Using stratified cluster sampling study area was stratified into 13 rural clusters, fifty houses were randomly selected from each stratum. All the elderly subjects, as defined by the age criteria were considered for study. The data were analysed using SPSS 20 v and Chi-square tests were used to analyse the data.Only 31.9% of participants reported visiting a dentist in the past while 36.7% reported experiencing a dental problem at some point in their life. There were no significant differences in utilization of dental services based on gender, socio-economic status, age groups and religion. However, significant differences were found in utilization of dental services based on the response of participants to past experience of dental problems.The present study results conclude that fear was one of the most commonly reported barriers for utilisation of dental services and there is a need for oral health education and promotion among elderly population.

This cross-sectional study was designed to measure the level and distribution of job satisfaction of registered dental practitioners and to explore the factors associated with it.The study was conducted among 66 registered dentists in Srikakulam, India. Job satisfaction was measured by using a modified version of the Dentists Satisfaction Survey questionnaire. The statistical tests employed were t test and analysis of variance (ANOVA). Post hoc test (Scheffe test) was employed for multiple comparisons.The response rate was 82.5%. The mean score of overall job satisfaction among dentists was 3.08 out of 5. The most satisfying aspect was income (3.7) and the least satisfying aspect was staff (2.5). Overall satisfaction increased with age. Male practitioners showed less satisfaction with staff, income, and overall satisfaction and more satisfaction in professional relations and time, when compared to females. Job satisfaction was found to be more in practitioners with postgraduate qualification.This study suggests that patient relations, perception of income, personal time, and staff are the important factors for job satisfaction among dentists. The findings of this study will be helpful to policymakers to design plans in order to increase the level of job satisfaction.

The presence of gingival recession associated with an insufficient amount of keratinized tissue may indicate gingival augmentation procedure. It is a multifaceted problem for which several treatment options are available. The most predictable technique used for gingival augmentation is the subepithelial connective tissue graft (SCTG). Platelet-rich plasma (PRP) is an enhanced source of growth factors and helps in accelerated periodontal repair and regeneration.The aim of this study was to evaluate the efficacy of SCTG along with PRP in the treatment of Millers class I and II gingival recessions.Eleven subjects with Millers class I and II gingival recessions were treated using SCTG with PRP. Clinical variables, including plaque index, gingival index, recession depth (RD), Recession width (RW), width of the keratinized gingiva, probing pocket depth (PD) and clinical attachment level (CAL) were recorded. Patients were recalled at baseline, 3 months, 6 months and 1-year after surgery and clinical recordings were taken. Root coverage percentage (%) was measured at the end of 1-year.The clinical parameters were analyzed during the follow-up period by repeated measures ANOVA test. Twelve months follow-up results showed significant improvements in all the clinical parameters. Reduction of recession resulted in a significant decrease in CAL, PD, RW and RD at the end of 12 months. A statistically significant gain in width of keratinized gingiva and a mean root coverage of 84.72 19.10 was obtained at the end of 12 months.From the results of this study, it may be concluded that SCTG with PRP is an effective and predictable method to treat millers class I and II gingival recession.

Studies on stress distribution around screw retained implants in different bone densities are limited. In clinical situations crowns of different heights are placed on the implants and the effect of varying crown implant ratio on the bone is not understood properly.To evaluate and compare the stress distribution in different screw retained implants for different crown-implant ratios in different bone densities under various occlusal loads using three dimensional finite element analyses.In this invitro study the stress distribution was evaluated and compared between two different crown heights (7.5mm, 10mm) retained on implants by using different screw materials (commercially pure titanium, titanium alloy) in two different densities of bone D2, D3 under various load (100N, 200N) applications by using finite element analysis.For crown height of 7.5mm, in D2 bone density when vertical load of 200N was applied, the maximum stress concentration was 1780N/cm(2), for oblique load of 100N it was 2936N/cm(2) respectively and in D3 bone density when vertical load of 200N was applied, the maximum stress concentration was 1820N/cm(2), for oblique load of 100N it was 3477N/cm(2) respectively. When the crown height is increased to 10mm, the maximum stress concentration in D2 bone was 1875N/cm(2) for vertical load, 4015N/cm(2) for oblique load and in D3 bone the maximum stress concentration was 2123N/cm(2) for vertical load and 4236N/ cm(2) for oblique load. In case of titanium screws for crown height of 7.5 mm, when vertical load was applied, stress concentration was 1603 N/cm(2) where as for titanium alloy screw it was 1820N/cm(2). In case of 10mm crown height stress concentration was 1904N/cm(2) for titanium screw and 2123N/cm(2) for titanium alloy screw. In case of oblique loading for 7.5mm crown height stress concentration was 3155N/cm(2) for titanium screw 3477N/cm(2) for titanium alloy screw. For 10mm crown height stress concentration was 4236N/cm(2) for titanium screw, 4663N/cm(2) for titanium alloy screw.Stress concentration was less and stress distribution was better in D2 bone density than in D3 bone density. Stress concentration was less and stress distribution was better in commercially pure titanium screw than in titanium alloy screw. With the increase in the height of crown (i.e., from 7.5mm to 10mm) stress concentration and stress distribution also increased.

Background: Lichen planus (LP) is a chronic mucocutaneous disease of uncertain etiology. Recent reports suggest that LP is an extrahepatic manifestation of Hepatitis C infection. Objective: To determine the association of Hepatitis C virus (HCV) infection with oral LP and to study the tests of liver function in patients with oral LP. Study Design: A cross-sectional case-control study was carried out on 25 patients with oral LP and an equal number of controls. The study was conducted in the outpatient department of a dental college for a period of six months between January and June 2008. The sera of the patients and controls were tested for HCV ribonucleic acid (RNA) using reverse transcription primed-polymerase chain reaction and liver function tests (bilirubin, transaminases, and alkaline phosphatase). Results: Of the 25 patients with LP, three (12%) had HCV infection. None of the controls had HCV RNA positivity (P = 0.2347). Oral LP patients had higher serum bilirubin and transaminases when compared with controls (P < 0.05). However, there was no significant difference in alkaline phosphatase. HCV-positive and -negative patients did not differ significantly in liver function tests. Conclusions: An increased prevalence of HCV infection was seen in oral LP patients. Our findings support a possible etiological association between these two diseases.

One of the factor which affects the strength of the tooth restored with core material is the property of the material. In clinical situation all such restored teeth are protected by crowns. This study evaluated the strength of different core materials on a compromised tooth structure after restoration with a crown.Seventy extracted intact human premolars were collected and mounted within a mould using auto-polymerizing resin. The teeth were divided in-to four groups - A, B, C and D. Each group contained 20 teeth except group A with 10 teeth. All the teeth were prepared for full veneer cast crown. Except for the teeth in group: A) extensive class-I cavities were prepared in the teeth of all the groups and restored with; B) composite resin, 3M EPSE Filtek P60; C) Silver reinforced glass ionomer, SHOFU Hi Dense XP and; (D) Resin reinforced glass ionomer, GC Gold Label light cure GIC. All the teeth were restored with cast-metal alloy and exposed to 1.2 million cycles of cyclic loading in a chewing simulator. Subsequently, the teeth that survived were loaded till fracture in the universal testing machine. Fracture loads and type of fractures were recorded.All the specimens survived cyclic loading. The mean fracture strength of the silver reinforced glass ionomer was greater with and without crown (p<0.001). Statistical analysis for the mean fracture load of each specimen showed significant difference between the groups.Under the condition of this study, core materials when restored with artificial crown had a significant increase in fracture resistance.

Periodontal plastic surgery is the branch of periodontology that is focused mainly on the correction or elimination of mucogingival problems associated with lack of attached gingiva, a shallow vestibule and aberrant frenum. Various mucogingival surgical procedures are used to halt the progression of the gingival recession and to correct poor esthetic appearance. Free gingival autograft is one of the most common techniques used for a gingival recession in areas of inadequate attached gingiva in the mandibular anterior region. Fibrin sealants are human plasma derivatives that mimic the final stages of blood coagulation, forming a fibrin clot. Fibrin Sealants enhances the overall outcome of surgical intervention because of their hemostatic, adhesive, and healing properties. These properties of fibrin sealants may reduce operating time, prevent complications, and enhance the overall outcome of many surgical interventions. Hence, this case report aims to investigate the clinical effectiveness of free gingival graft along with the commercially available fibrin-fibronectin sealing system (Tissucol()) in the treatment of Millers class II gingival recession.

Lower incisor extraction in orthodontic treatment was very rare modality of orthodontic treatment because there are few patients who meet the standards for such treatment. Proper diagnosis and treatment planning should be done to achieve good occlusion and facial esthetics. Criteria for lower incisor extraction included degree of crowding, tooth size discrepancy, pathologic condition, vertical overbite, sagittal incisal relationship, skeletal growth pattern and age of the patient. This article comprises of a case of class I malocclusion treated with lower incisor extraction, with comprehensive analysis, diagnosis and treatment planning, treatment results were satisfactory.Mandibular incisor extraction can be an effective treatment option in borderline cases with mild crowding in lower arch. Minimal alteration of mandibular arch form is key factor for success and stable results.
