Patient is oft en completely or partially edentulous at the stage of primary (4-5 yrs) and permanent dentition (13-15 yrs). Though, exact etiopathogenesis is unknown; three major factors have been identifie d as accountable for its initiation and progression. These are hereditary, immunological an d microbial factors . Total rehabilitation in such cases is often difficult for health care profe ssionals. However, correct diagnosis, perfect treatment planning and appropriate prosthodontic re habilitation of such unfortunate individuals can improve their oral functioning, esthetics and o verall social life. Here is a clinical report of such a rare condition with special focus on its dia gnosis, characterization and rehabilitation by removable prosthodontics.

The prime target of the material has always been to provide a three-dimensional obturation providing a monoblock concept thus strengthening the tooth. Aim: The aim of the study was to evaluate the fracture toughness of the root canal treated teeth after being oturated with GuttaPercha and Resilon by lateral and vertical compaction techniques. Materials and Methods: A total of 75 human mandibular premolar teeth were taken and endodontically treated. All the teeth were divided into five groups with 15 samples in each. Access opening of all the teeth was done, and the cleaning and shaping were done up to 40 number file size. The samples were obturated with two materials which are Gutta-Percha and Resilon. All the teeth were subjected to compressive loading till the fracture occurred, and the readings were taken and compared. It was found that the teeth obturated with Resilon showed higher fracture resi...

It also describes a simplified method of fabricating two piece hollow obturator with magnets and rehabilitating a patient with hemimaxillectomy and enhances vision on various prosthetic guide lines in rehabilitating patients with acquired maxillary defects. AIMS AND OBJECTIVES: The main objective of the article is to mainly describe an alternative method to treat a patient with an acquired defect of maxilla with restricted mouth opening. MATERIALS USED AND CASE STUDY: The author constructed a prostheses which was given to a male patient aged sixty two years had come 10 the hospital with a large tumor in the maxilla. He had a history of reverse smoking. After careful examination the patient was diagnosed with squamous cell carcinoma. The patient was referred to surgical oncologist and tumor was resected based on some surgical and prosthodontic guide lines for reconstruction. After complete healing of the a...

This undue stress build-up and improper coping skills may lead to maladaptive behaviors. Aim : To determine oral hygiene behavior among prison inmates; and to correlate the oral hygiene behavior with stress level and coping styles of the inmates. Methods: The study design was cross-sectional. A prison in Northern India was randomly selected for the study, and appropriate official and ethical approvals were obtained from concerned authorities. Questionnaires were utilized to collect information about oral hygiene behavior, stress level and coping styles of the inmates. The questionnaires ware pretested and appropriate changes were made to improve the comprehensibility. Results: A great majority of the inmates (88%) clean their teeth, and more than two-third (69%) of them clean their teeth once or more daily. The perceived stress level for inmates was moderately high, and adapt...

Three resin composites, one nanohybrid, one nanoceramic, and one bulk-fill resin-based composite, were used in this study. Cylindrical Teflon mold and 8 mm in diameter and 2 mm in thickness disc specimens were prepared. For each composite material, 15 discs were fabricated, with a total of sixty discs were obtained (= 60). A glass slide 1-2 mm thick was placed over the strip before curing with the light-curing unit to flatten the surfaces. The specimens were then cured for 40 s through the Mylar strip and the glass slide. Five specimens per each material received no finishing treatment after being cured under Mylar strips; these specimens served as a control. Ten specimens from each composite material were finished/polished with Eve discs at coarse, medium, fine, and superfine grits for 30 s (using stopwatch) each on the specimens. After polishing, the composite surfaces were assessed quantitatively by profilometry a...

One of the factors contributing for the increasing use of base-metal alloys is the increasing and high cost factor of noble metals. Although numerous materials have been tried since the recent past, Cobalt-Chromium (CoCr) alloys still form the most commonly used ones because of the numerous advantages they offer. Titanium alloys are also significantly being used in this field because of their high resistance strength and high corrosion resistance. Therefore, we aimed to evaluate the flexure strength and fatigue resistance of clasps made up of CoCr alloys and Nickel-titanium (NiTi) alloys. We evaluated the retentive forces of CoCr and NiTi clasps two different sizes engaging retentive undercuts of different depths (0.25 and 0.50 mm). Mandibluar second premolar was prepared to frame the prosthesis for missing mandibular first and second molar. A total of 50 cl...

As and when the periodontal diseases affect the furcation area of a tooth; the chance of its exfoliation increases significantly. Such clinical problems make it difficult for the patient to maintain hygiene, and impede adequate treatment. The treatment of furcations affected by periodontal disease is one of the most difficult problems for the general dentist and periodontist. Molar bisection is one modality option which is actually the separation of mesial and distal roots of mandibular molars along with its crown portion, where both segments are then retained individually. Here authors have genuinely attempted to congregate a comprehensive review of literature on this obscured field of clinical dentistry.
