Aim: To evaluate factory-sealed containers of three different commercially available irreversible hydrocolloid impression materials for their microbial contamination and the type of microorganisms present. Materials and methods:Thirty-six measured samples were taken of each brand and placed on chocolate agar plates or in thioglycolate broth tubes and were incubated along with appropriate parallel controls. After incubation, colonies were enumerated and identified using standard microbiological methods.

Oligodontia is a developmental anomaly which represents the congenital absence of more than six teeth in primary, permanent, or both dentitions and may or may not be associated with a syndrome. These patients suffer from occlusal disharmony, problems in speech and esthetic appearance. A multidisciplinary approach becomes mandatory to manage such patients to rehabilitate their oral function. Therefore, early diagnosis and treatment become important. This is a case report of a 15-year-old female patient with oligodontia, who was rehabilitated with removable overlay prostheses fabricated digitally, without modifying her existing dentition, to restore mastication, phonetics, and esthetics. Such an approach is essential for children who have not completed their growth. The monolithic three-dimensional (3D) printed denture has increased fracture resistance and higher wear resistance compared to conventional denture. It can also be easily adjusted, repaired and if required, reproduced. This article highlights the methodology, pros and cons of fabricating 3D printed dentures for such patients.

Patients presenting with flabby or displaceable tissue continue to challenge even the most competent dental practitioners A fibrous or flabby ridge is a superficial area of mobile soft tissue affecting the maxillary or mandibular alveolar ridges. It can develop when hyperplastic soft tissue replaces the alveolar bone and is a common finding particularly in the upper anterior region of long-term denture wearers. Masticatory forces can displace this mobile denture-bearing tissue, leading to altered denture positioning and loss of peripheral seal. Under compression, the denture bearing area will exhibit localised mobility around the flabby tissue. Unless managed appropriately, such “flabby ridges” adversely affect the support, retention, and stability of complete dentures. Many impression techniques have been proposed to help overcome this difficulty Selective impression techniques have long been used in such cases, ensuring the displaceable tissue is recorded 'at rest'. Subsequently, the denture will maintain its peripheral seal during function This article presents a case report for prosthodontic rehabilitation of a patient with flabby ridge with a window tray impression technique, modified with dual trays.

Excessive occlusal wear of dentition can result in pulpal injury, occlusal disharmony, impaired function and esthetic deformity. Wear of teeth can be in the form of attrition, abrasion, erosion, abfraction etc. Severe loss of anterior teeth results in loss of anterior guidance this compromise's the posterior teeth during excursive movement. Such excessive wear and abnormalities of teeth often impairs patients basic activities like mastication, speech and esthetics affecting patients life style. Therefore reconstruction of the mutilated dentition is necessary. Full mouth rehabilitation combines esthetics with the science of restorative dentistry to improve the health and function of the patient. This clinical case report describes the use of hobo twin-stage procedure for rehabilitation of a patient with severe tooth wear and reduced vertical dimension of occlusion.
