To compare the acidogenic potential of plain milk, milk with sugar, milk with cornflakes, and milk cornflakes with sugar by assessing the salivary pH.The study was carried out on 40 school children of 8 to 12 years; 20 boys and 20 girls were randomly selected. The salivary pH was assessed before and after the consumption of milk; milk and sugar; milk and cornflakes; and milk, sugar, and cornflakes. Baseline unstimulated saliva was collected in sterile plastic tube and the pH was recorded. The change in the salivary pH from the respective groups after consuming the test meal was recorded as follows: (1) after 5 minutes; (2) after 10 minutes; (3) after 15 minutes; (4) after 30 minutes; (5) 120 minutes. Statistical analysis was done using Statistical Package for the Social Sciences 18.0 (SPSS).The average baseline salivary pH among all the groups was 7.26. A fall in pH at 5 minutes was seen in all the four groups. However, at different time intervals 5, 10, 15, 30, and 120 minutes, the pH values between the groups showed a significant difference at p < 00.7, 0.005, 0.001, 0.010, and 0.028 respectively.The fall in pH in all the groups was not significant to a limit of critical pH. Milk when added with sugar and/or cornflakes as a meal did not pose a threat as there was not significant decrease in pH.Bhat SS, Hegde SK, Bhat VS, Ramya KM, Jodalli PS.

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.

The mandible has a property to flex inwards around the mandibular symphysis with change in shape and decrease in mandibular arch width during opening and protrusion of the mandible. The mandibular deformation may range from a few micrometres to more than 1 mm. The movement occurs because of the contraction of lateral pterygoid muscles that pulls mandibular condyles medially and causes a sagittal movement of the posterior segments. This movement of mandible can have a profound influence on prognosis and treatment outcome for various restorative, endodontics, fixed, removable and implant-related prosthesis. The review unfolds the causes, importance and clinical implications of median mandibular flexure in oral rehabilitation. This review also highlights the appropriate preventive measures and techniques that should be adopted by clinicians to minimise the effect of flexural movement of the jaw during oral rehabilitation. This would not only help clinicians to achieve a good prosthesis with accurate fit and longevity but also maintain the health of the surrounding periodontal or periimplant gingival tissues and bone.

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.

Phosphatase and tensin homolog (PTEN) is a tumor suppressor gene located on chromosome 10q23. PTEN has its major function in the regulation of cell adhesion, cell cycle arrest, migration, apoptosis programming, and differentiation. This genomic region suffers loss of heterozygosity in many human cancers.The aim of this study was to compare the immunohistochemical expression of PTEN in normal oral mucosa and oral squamous cell carcinoma (OSCC) and to correlate the PTEN expression in gradings of OSCC.Thirty cases of paraffin tissue sections of previously diagnosed OSCC were taken. Of thirty cases, ten were well differentiated, ten were moderately differentiated, and ten were poorly differentiated. As a control, ten paraffin sections of oral normal mucosa tissue specimens were taken from patients undergoing extractions. The sections were stained for immunohistochemical expression of PTEN. The cells stained by PTEN antibody were counted, and an immunohistochemical score was obtained.Statistical analysis was done using Mann-Whitneys test and Kruskal-Wallis test.Statistical analysis revealed that there was a significant difference between normal mucosa and OSCC in immunohistochemistry staining. However, there was no significant difference in PTEN expression among gradings of OSCC.The study concluded that there was a decrease in PTEN expression in OSCC than normal mucosa. It also concluded that PTEN is a tumor suppressor gene which has a wide role in oral carcinogenesis.

Anesthesiologists consistently work in the mouth of patients but are not exposed to comprehensive education of teeth, the surrounding structures, and intraoral prosthesis. One of the most common adverse events related to anesthesia is perioperative dental damage. To minimize these dental injuries, a preoperative assessment of patient's dentition and intra-oral tissues should be undertaken.

To partially assess the efficacy of probiotic lozenges, in the treatment of periodontal disease. Material and methods: Twenty eight subjects, of both sexes, were selected and divided into 4 groups (2 test groups and 2 control groups).The test group was instructed to consume probiotic lozenges whereas the control group did not receive any probiotic product. Clinical parameters such as plaque index, gingival index, modified sulcular bleeding index and probing pocket depth were recorded and assessed at baseline, day 15, 30, 45 and day 60. The Test group showed significant reduction in all parameters when compared to that of Control group. After stopping probiotic administration on day 30, the test group showed a significant increase in all the clinical parameters except probing pocket depth on day 45 and day 60. Conclusions: The results show that probiotic lozenges were efficacious in reducing both moderate to severe gingivitis and moderate periodontitis.

Purpose: Genetic factor to bitter taste perception appears to be largely mediated by the TAS2R38 gene. The insensitivity to bitter compounds like 6-n-propylthiouracil (PROP) is mediated by this gene. PROP, a pharmacological drug used in treatment of Graves disease, proved to be useful tool in determining the genetic sensitivity levels to bitter and sweet taste. The purpose of this study is to show much simpler PROP sensitivity technique for the clinical examiner and its application as a diagnostic aid in Early Childhood Caries (ECC) detection among preschool children. Materials and Methods: A total of 119 children belonging to the age group of 36 to 71 months of both sexes, were recruited from A. J. Institute of Dental Sciences, Mangalore (Karnataka). PROP sensitivity test was carried out to determine the inherent genetic ability to taste a bitter or sweet substance. This study used simpler scaling method to find out genetic sensitivity to bitter taste; one who tasted bitter as taster and one who was not able to differentiate/tasted like paper as non-taster. A questionnaire was provided to evaluate their dietary habits and caries experience was recorded. Collected data were tabulated and subjected to statistical analysis. Results: In the total of 119 children the mean dmfs was definitely higher in non-taster children compared to tasters. The tasters had a mean dmfs value of 9.5120 (S.D. 7.0543) and non-tasters had a value of 7.7250 (S.D. 8.33147), which was statistically significant. The results suggested that there was increase in caries experience among the group of non-tasters as compared to tasters. Tasters tended to be sweet dislikers and non-tasters tended to be sweet likers. On the whole, tasters had a bad dentition as compared to non tasters. Conclusion: The PROP sensitivity test (filter paper test) proved to be a useful diagnostic tool in determining the genetic sensitivity levels of bitter taste. The knowledge of a childs taste perception can help us in identifying the children who are at higher risk for ECC.

Fibrous dysplasia (FD) is a condition characterized by excessive proliferation of bone forming mesenchymal cells which can affect one bone (monostotic type) or multiple bones (polyostotic type). It is predominantly noticed in adolescents and young adults. Fibrous dysplasia affecting the jaws is an uncommon condition. The most commonly affected facial bone is the maxilla, with facial asymmetry being the chief complaint. The lesion in many instances is confused with ossifying fibroma (OF). Diagnosis of these two lesions has to be done based on clinical, radiographic, and microscopic findings. Here, we present a case of fibrous dysplasia of maxilla in a nine-year-old boy mimicking juvenile ossifying fibroma.
