 Abstract

Angina Bullosa Hemorrhagica (ABH) describes benign sub-epithelial oral blood blisters that are not attributable to a systemic disorder. ABH is predominantly seen in the soft palate, and its pathogenesis is not well understood, although most cases have been associated with mild trauma prior to the appearance of the lesion. The haemorrhagic bulla is often painless and present for a short period of time in the oral cavity. It ruptures spontaneously to form superficial erosions that heal without scarring, making it a self-limiting condition. Diagnosis is important to rule out vesiculobullous disorders, blood dyscrasia, and other systemic diseases. Here we present a case report of ABH affecting the soft palate. Interestingly, the haemorrhagic bulla developed after food ingestion, and the lesion ruptured spontaneously to form a painful ulceration in the soft palate. Symptomatic treatment was given, and the ulcer healed without scarring after 3 days. ...Read More >>

 Piezo Surgery - A Novel Application in Dentistry

 Abstract

Piezosurgery is a new and innovative method that uses piezoelectric ultrasonic vibrations to perform precise and safe osteotomies. It was first invented by Tomaso Vercelotti to overcome the limitations of traditional instruments in oral bone surgery. Its use was first reported in the field of preprosthetic surgery, alveolar crest expansion, and sinus grafting. It provides substantial improvement in dental/implant surgery, benefiting the surgeon by ease of use and the patient by minimizing surgical trauma and promoting rapid healing. This article discusses the wide range of applications of this novel technique in periodontology. ...Read More >>

 Fibroblast Heterogeneity in Periodontium – A Review

  

  A. Archana , C. S. Krishnan , J. Selvakumar

 Abstract

Fibroblast heterogeneity refers to both phenotypic and functional properties exhibited by a fibroblast population within or across tissues (Mc Culloch et al.). There is significant evidence that fibroblasts are heterogeneous with respect to functional properties. Certain subpopulations of these cells may be clonally selected and expanded in diseased tissues. There are wide variations in gene expression and strikingly different responses to extracellular signals among different fibroblast populations. This has prompted a large number of in vitro studies, which suggest that fibroblasts are not homogeneous. Instead, they comprise multiple subpopulations with extensive site-to-site and intra-site variations. ...Read More >>

 Sialendoscopy – Less Invasive But More Accurate

  

  A. G. Manimegalai , C. Pravda

 Abstract

Salivary gland ductal obstruction is a frequently presenting disorder of the salivary glands. Diagnosis of this condition includes ultrasound, sialography, or MR sialogram. However, each technique has its own limitations. Endoscopy of salivary glands allows optical exploration of the salivary gland system and incorporates both diagnostic and therapeutic procedures for intraductal pathologies like sialilithiasis. Sialendoscopy is one of the most fascinating innovations in the field of Head and Neck Surgery and was introduced in the early 1990s. As a minimally invasive technique, sialendoscopy has shifted from conventional open surgical resection procedures to endoscopic and gland preservation techniques. This article enlightens this novel technique, which will soon be included in the repertoire of all clinicians in the future. ...Read More >>
