Aim: The purpose of this study was to compare the effectiveness of orthodontic brackets to tooth with conventional, Self-etching and Nano bonding agent. Materials and Method: Specimen consisted of premolar on which the premolar brackets were bonded with light cure adhesive system.The specimens were divided into 3 groups of 12 teeth. Group I were bonded using conventional bonding agent,Group II was bonded using Self-etching primer and Group III was bonded using Nano bonding agent.The shear bond strength was recorded by Instron at a cross head speed of 1 mm/ min until the bracket debonds. Results: It was observed that the Group III had a (10.05) higher mean value than the other Group I (18.73), Group II (5.48). Findings indicated no significant difference between conventional and Nano bonding agent. However self-etching primer displayed adequate bond strength. Conclusion: The results of the study were promising as always for conventional and Nano bonding agent. Though Self-etching primer produced comparable shear bond strength to that of conventional light cure and would save chair time.

Quorum sensing is a cell density-dependent signal transduction system, which controls a variety of the physiological behavior in bacteria. During quorum sensing, bacteria produce and secrete the small signal molecules outside the cell to recognize the population density. Quorum sensing is a system used by bacteria to detect population density and respond. This communication is carried out by molecular signals produced and released by the bacteria. The signals disperse to nearby individuals and eventually lead to a pathway that causes induction of more signal production in those neighbors, in addition to other desired genes. The denser the population, the higher concentration the signal is. This circuit creates a positive feedback loop that causes the population to work in sync. In nature, bacteria can use quorum sensing for functions such as bioluminescence, virulence, and biofilm formation. Because quorum sensing is such an important aspect of biofilm formation, it is a valuable topic of research for disease prevention and treatment in the field of medicine and dentistry.

Type IV gypsum product is the commonest die stone material, obtained from natural gypsum rock. It is workable, economical and involves least equipment. Its advantages far outweigh its shortcomings. Hence is very widely used.

Medical tourism is patient movement from highly developed nations to other areas of the world for medical care, usually to find treatment at a lower cost. Medical tourism is different from the traditional model of international medical travel where patients generally journey from less developed nations to major medical centres in highly developed countries for medical treatment that is unavailable in their own communities. India stands out be one of leading destinations providing healthcare services along with other developing nations. While some patients benefit immensely from this industry, others are subjected to a number of complications and illegal practices. However, despite the conflicts of opinions, this industry is continuing to grow and is major source of income for some developing nations.

Majority of paediatric dental patients reveal a great anxiety and fear during routine oral procedures. Such attitude of children to dental procedures is a cause of irregular visits to dental clinics, which, in consequence, may lead to greater damage to teeth, which otherwise could have been saved by simple procedures. Clinical hypnosis could be a non-invasive therapeutic option to increase treatment comfort both for the patients and dentists. This article gives an overview about some basic facts and indications for hypnosis in pediatric dentistry. Management of fear and anxiety, hypnosis for dental analgesia, control of bleeding, control of salivation, control of bruxism, control of gag reflex, could be controlled by pediatric dental hypnosis.This kind of psychotherapy may be used in everyday dental practice; however some profound knowledge in this field is needed for pedodontist.

Maxillary sinus is an important paranasal sinus. The signs and symptoms of the sinus disorder is commonly manifested in the region of the maxillary tooth. Due to its close proximity to the oral cavity, eye and base of the skull, the sound knowledge of the diseases affecting this structure is very important. Here we review the different diseases affecting the maxillary sinus.

Purpose: To describe a protocol for immediate placement of endosseous implant into debrided infected dentoalveolar socket. Patient and methods: A total of 2 implants were placed in a patient with infected dentoalveolar socket in relation to 11. The Immediate placement protocol emphasized the meticulous debridement of the infected tissue in combination with periapical osteotomy of socket. Bone grafting along with Collagen membrane was accomplished to support bony healing of alveolar defects surrounding implantation site. Pre-surgical and postsurgical antibiotic therapy was administered. Results: This is a case report demonstrating the benefits of immediate implant placement coupled with bone grafting for esthetic rehabilitation of an anterior missing teeth & anterior facial cortical bone defect. Both the implants osseointegrated after 6 months follow up and were functional 6 months postoperatively. Conclusion: Successful immediate implantation in debrided infected alveolus depends on complete removal of all contaminated tissue and the controlled regeneration of the alveolar socket.

This is a case report of a unique zygomaticomaxillary frontotemporal complex (ZFT) fracture that is rarely reported in the literature.

Lateral periodontal cyst is an unusual type of developmental odontogenic cyst. It develops in the periodontal ligament adjacent to the lateral surface of the root of an erupted tooth.It seems to arise from reduced enamel epithelium, remnants of dental lamina and cells of malassez. Most commonly reported location is mandibular premolar area, followed by the anterior region of the maxilla. Following is a case report of a patient who reported to Department of Periodontics, Rajah Muthiah Dental College Hospital, with a swelling in the labial aspect of left upper front teeth region. It was diagnosed as Lateral periodontal cyst based on clinical, radiograghic & histo-pathological examination.

Peripheral Ossifying Fibroma is a reactive benign lesion of the connective tissue and is not the soft tissue counterpart of Ossifying Fibroma. This lesion is more common in the second decade of life with higher predilection for females. The lesion is more common in the anterior maxilla. Here we present a case report of Peripheral Ossifying Fibroma in a 60 year old female.

Esthetics is becoming an important concern in periodontics. Gingival recession which causes tooth hypersensitivity, due to root exposure and an unesthetic appearance with uneven gingival margin levels requires a simple and a predictable technique for root coverage. Various techniques for treating gingival recession include flap surgical procedures like coronally repositioned flap, lateral sliding flap, double papilla flap, semilunar flap and procedures using graft materials in combination with flap procedures like connective tissue graft, bioabsorbable or non resorbable membrane or enamel matrix derivatives. Maxillary tuberosity has a greater bulk of gingival tissue which can be harvested with ease with minimal complications compared to the palate where vital anatomic structures, such as greater palatine artery, limit the size and amount of connective tissue and has a higher rate of complication. A gingival cuff from the maxillary tuberosity area can be easily adapted to the recipient site by just removing the epithelium with no risk of associated complications and an esthetically pleasing outcome. This article presents a case report where complete root coverage is obtained with gingival cuff of maxillary tuberosity.

Oral squamous papillomas are benign tumors of the oral cavity presenting as a verrucous exophytic growth. Most of the papillomas are asscociated with human papilloma virus. The common sites of occurrence include the palatal complex, uvula, tongue and gingiva. Its malignant transformation is documented in other sites such as the trachea and the larynx. With evidence of HPV infections leading to cervical cancer and papilloma in other regions showing malignant transformation the question of whether oral squamous papilloma should be considered a potentially malignant disorder needs to be addressed. An occurrence of a large papilloma on the buccal mucosa, an unusual location is reported here.
