A broad array of behavioral symptoms, including psychosis, can transpire post-operatively following a variety of surgeries. It is difficult to diagnose the exact cause of post-operative psychosis. We report three cases, which developed psychosis post-operatively after undergoing major oral and maxillofacial surgeries. All the three patients were administered dexamethasone peri-operatively. Dexamethasone is used to prevent or reduce post-operative edema. The exact dose of dexamethasone, which can cause psychosis, is unknown. It is important to raise awareness about this potential complication so that measures for management can be put in place in anticipation of such an event.

Objectives To report a case of an elderly patient with an unstable mental condition, presenting with the carcinoma of lip due to repeated toothpick injury. Background Self-induced lesions of the face and mouth may be a manifestation of unusual or aggressive oral habits or an emotional disorder. The deliberate creation of orofacial lesions, is an indication of underlying psychiatric disease. Betel quid chewing is the major risk factor for oral cancer. It conditions the oral mucosa towards the development of cancer. Repeated trauma by self mutilation on such a conditioned mucosa can lead to the development of cancer. Materials and methods A male patient aged 85 years reported the complaint of a growth on the left side of the lower lip. Trauma followed by self inflicted injury had predisposed to the formation of cancer. Conclusion Diagnosis of self inflicted lesions are challenging as the histories of these lesions tend to be vague and misleading. Our knowledge in this particular pathology is limited mainly because of diagnostic difficulties and lack of solid statistical data. © 2013 John Wiley & Sons A/S and The Gerodontology Society.

Introduction: Anchorage control is a critical consideration when planning treatment for patients with dental and skeletal malocclusions. To obtain sufficient stability of implants, the thickness of the soft tissue and the cortical-bone in the placement site must be considered; so as to provide an anatomical map in order to assist the clinician in the placement of the implants. Objective: The aim of this study is to evaluate the thickness of soft-and hard-tissue. Materials and Methods: To measure soft tissue and cortical-bone thicknesses, 12 maxillary cross-sectional specimens were obtained from the cadavers, which were made at three maxillary mid-palatal suture areas: The interdental area between the first and second premolars (Group 1), the second premolar and the first molar (Group 2), and the first and second molars (Group 3). Sectioned samples along with reference rulers were digitally scanned. Scanned images were calibrated and measurements were made with image-analysis software. We measured the thickness of soft and hard-tissues at five sectional areas parallel to the buccopalatal cementoenamel junction (CEJ) line at 2-mm intervals and also thickness of soft tissue at the six landmarks including the incisive papilla (IP) on the palate. The line perpendicular to the occlusal plane was made and measurement was taken at 4-mm intervals from the closest five points to IP. Results: (1) Group 1:6 mm from CEJ in buccal side and 2 mm from CEJ in palatal side. (2) Group 2:8 mm from CEJ in buccal side and 4 mm from CEJ in palatal side. (3) Group 3:8 mm from CEJ in buccal side and 8 mm from CEJ in palatal side. Conclusions: The best site for placement of implant is with thinnest soft tissue and thickest hard tissue, which is in the middle from CEJ in buccal side and closest from CEJ in palatal side in Group 1 and faraway from CEJ in buccal side and closest from CEJ in palatal side in Group 2 and faraway from CEJ in buccal side and faraway from CEJ in palatal side in Group 3.

The incidence of oral cancer in India is on the rise due to increasing consumption of alcohol and tobacco products. The study was conducted with the aim to assess the associated knowledge in adults attending a dental college. Specific objectives were to: 1) assess the knowledge of risk factors for oral cancer 2) assess the knowledge of signs of oral cancer; 3) determine factors influencing level of knowledge. All adult patients visiting the dental college were randomly selected to participate in a questionnaire survey, printed both in English and the local language - Kannada. Some 69.8% (n=166) and 37.8% (n=90) respectively were able to correctly identify tobacco and alcohol as risk factors for oral cancer. Only 20.2% (n=48) and 18.1% (n=43) respectively were able to correctly identify a white lesion and a red lesion as early signs of oral cancer. Respondents who were younger, those who had >12yrs of education were more likely to be more knowledgeable of risk factors for oral cancer. Those with higher knowledge of risk factor scores were 4.5 times more likely to obtain ≥1 knowledge of signs score. (p< 0.0000). Knowledge of risk factors and signs of oral cancer was low and misinformation was high, hence there is a need to focus on educational interventions in a hospital based setting to improve knowledge.

Aim: To evaluate and compare the efficacy of preprocedural mouthrinses (chlorhexidine digluconate and tea tree oil) in reducing microbial content of aerosol product during ultrasonic scaling procedures by viable bacterial count. Settings and design: It was a randomized single blind, placebocontrolled parallel group study. Materials and methods: Sixty subjects were randomly assigned to rinse 10 ml of any one of the mouthrinses (chlorhexidine digluconate or tea tree oil or distilled water). Ultrasonic scaling was done for a period of 10 minutes in presence of trypticase soy agar plates placed at standardized distance. Plates were then sent for microbiological evaluation for the aerosol produced. Results: This study showed that all the antiseptic mouthwashes significantly reduced the bacterial colony forming units (CFUs) in aerosol samples. Chlorhexidine rinses were found to be superior to tea tree when used preprocedurally in reducing aerolized bacteria. Conclusion: This study advocates preprocedural dural rinsing with an effective antimicrobial mouthrinse during any dental treatment which generates aerosols, reduces the risk of crosscontamination with infectious agents in the dental operatory. Clinical significance: The aerolization of oral microbes occurring during dental procedures can potentially result in cross-contamination in the dental operatory and transmission of infectious agents to both dental professionals and patient. It is reasonable to assume therefore, that any stratagem for reducing the viable bacterial content of these aerosols could lower the risk of cross-contamination.
