ABSTRACT : Aims: Aim of the study was to evaluate and compare the bond interface between different denture base resin and soft liners, with varying liner thickness after three months of aging. Material and Methods: Two denture base resins Lucitone, Trevalon HI and two soft liners Permasoft, Mollosil were used to prepare the specimens. Total 112 heat cure resin and soft liner combination specimens were prepared. Results: After three months, both the liners showed significant increase in mean values of bond interface, indicating weakening of bond. Conclusion: After three months, Mollosilsoft liner (silicone-based) showed better dimensional stability than Permasoft (acrylic based liner).

Keywords: Bond interface, denture base (DB) resin, integrity, aging, soft liner.

ABSTRACT:

Introduction: Results: Higher mean values for both MI and PMI were observed in pre-menopausal group with statistically significant differences than indices related to menopausal status. Lower mean values for PMI and MI were observed in chronic periodontitis patients in both the groups, but statistically significant relationship between MCI and chronic periodontitis in both pre and post- menopausal group. Conclusion: The results of the study suggested that positive co-relationship exist between osteoporosis and chronic periodontitis but is more evident in post menopausal women but it needs further long term evaluation on large sample size before reaching final conclusion . Periodontitis is an inflammatory disease that leads to alveolar bone loss. Severe osteoporosis could be suspected of being an aggravating factor in case of periodontal destruction. Use of panoramic- based indices can be reliable tools for osteoporosis screening. Aims: To evaluate the relationship between chronic periodontitis and osteoporosis using different radiomorphometric indices; mandibular cortical index (MCI), mental index (MI), and panoramic mandibular index (PMI) in pre- and post- menopausal women. Settings and Design: Cross- sectional study Materials and Method: Eighty female patients with the age range of 33-62 years; visiting the Department of Periodontology , were selected and divided into two groups viz; group I (pre-menopausal group) and group II (post-menopausal group). Both the groups were further subdivided into sub group A (chronic periodontitis patients) and sub group B (periodontally healthy patients). Panoramic- based indices were measured, recorded and statistically analysed. statistical analysis: Student-t test was applied to compare mean values of MI and PMI. Intra and inter group comparison of MCI were made using chi-square test. Correlation of age and MI and PMI was found by Pearson’s correlation coefficient.

ABSTRACT : Background: The dental profession is the most stressful of all the health profession, and this is true for all stages of the dental career, i.e. for established dentists, young dentists and dental students. The aim of the study was to identify self-reported sources of the stress among the dental undergraduates students in a dental teaching institution in Rajasthan, India. Materials and Method: Modified dental environmental stress (DES) questionnaire having 32 items on a 4-point likert scale addressing 4 stressor domains were administered to the undergraduate students of the institution. Descriptive and bivariate ananysis based on chisquare test were performed. Results: The most stress provoking factor was found to be ‘Insufficient spacing between exam dates’ followed by ‘Examination and grades.’ The least stress provoking factor was related to Personal issue such as relation with friends and seniors and discrimination due to race, social class or ethnic group. Conclusion: The result of the current study indicate that with the advent of newer teaching modalities, a more students friendly environment can be created so that detrimental consequences of stress can be reduced. Academic and nonacademic perceived sources of stress should be considered in curriculum planning and in the working environment for dental education.

Abstract: One of the most controversial area still remaining in the treatment of cleft lip and palate has to do with the use of presurgical orthopedic treatment ( PSOT) as a supposedly viable and beneficial concept and whether it is superior to conservative nonorthopedic treatment. Pre-surgical orthopedics was first described by Kerr McNeil in Glassgow who used special obturator with stimulation pads in cleft children. Proponents of PSOT claim that it helps in reducing size of cleft, tongue behavior modification, improved speech, decreased ear infections, expansion of collapsed maxillary segments; and support to parents at a difficult time. Opponents of PSOT claim that cleft reduces in size without pre-surgical treatment, feeding of cleft patients can be done without obturation etc.

Abstract: Space closure procedure in orthodontics involves two types of mechanics that are sliding or frictional mechanics and frictionless mechanics. Sliding mechanics uses elastomeric chains, closed coil springs and elastic module with ligature. In frictionless mechanics loops and springs are used. In this article various type of loops used in frictionless mechanics are discussed.

Key-words: Friction less, moment force ratio, space closure.

Abstract : Bio esthetics is the quintessence of biology, biomechanics and esthetics. It aims to be more conservative and ethical solution to a myriad of esthetic deficiencies.A more attractive smile, improved dental esthetics and durable results have been for long intimately linked to ceramic restorations such as veneers and crowns and remain strongly anchored in patients and dental professional minds.Despite the availability of a wide range of restorative materials, none could match the properties of natural tooth structure like translucency, wear resistance, and color stability. This rationale has been the foundation of a new concept named ‘bio-esthetics’, giving priority to additive, minimally or micro invasive procedures to preserve tooth biology and biomechanics. The aim of this review article is to discuss the various bio-esthetic treatment approaches.

Abstract: Rehabilitation of a patient with partial resection of soft palate is a prosthodontic challenge. Surgery is the preferred treatment for speech correction in patients affected by velopharyngeal dysfunction which may not be feasible in many clinical situations. Prosthetic treatment combined with speech therapy is the treatment of choice in such patients who cannot be managed with surgical treatment. In velopharyngeal dysfunction, hypernasality and regurgitation of food and liquids is common if defect is not obturated. This case report describes rehabilitation of a patient with soft palate defect and subsequent velopharyngeal insufficiency by a velo-pharyngeal prosthesis.

Abstract:  Keratocystic Odontogenic tumour (KCOT) is a benign neoplasm defined by the World Health Organization as a benign uni or multicystic, intra osseous tumour of odontogenic origin with a characteristic lining of parakeratinised stratified squamous epithelium and a potential for aggressive and infiltrative behavior (the ability to expand through bony walls and invade deeper structures); with high recurrence rate (0 to 62%). The posterior body and ramus are the most commonly involved sites in the mandible. Treatment of KCOTis still controversial due to difference in opinion among different surgeons as some prefer conservative treatment but the rate of recurrence was higher whereas others prefer surgical resection as it reported to have very low recurrence. The following paper features the diagnosis and successful management of KCOT by surgical resection and secondary reconstruction.

Abstract: Cutaneous sinus tracts of dental origin are uncommon and often initially misinterpreted and inappropriately treated because of their uncommon occurrence and the absence of symptoms. The microbiologically induced inflammation or infection follows the path of least resistance by penetrating the alveolar bone. They usually cause the soft tissue to swell or form an intra-oral fistula. However, the infection can break through the skin making it look like a bad pimple. These conditions are often misdiagnosed as other non-pulpal pathologies, which may lead to unnecessary invasive treatment of skin lesions. The present case report deals with the successful non-surgical endodontic treatment which led to healing of extra-oral lesion and closure of sinus tract.

Abstract: This case report describes the treatment of a 16 years old female who had a skeletal class I with anterior vertical maxillary excess and canting of occlusal plane on left side with dental class I malocclusion, increased overbite and reduced overjet. Treatment was performed with a modified surgery first approach, which included a short pre-surgical alignment phase segmentally, so that anterior step can be maintained followed by maxillary anterior subapical osteotomy and the use of the inherent increased bone turnover in the post-surgical phase (RAP) helped to reduce the total orthodontic treatment time. Pleasing esthetic results and good functional occlusion were achieved.
