Dentistry, being one of the healing professions, has an obligation to society that its members will stick on to high ethical standards of conduct. In India, studies done to assess whether the dental practitioners adhere to ethics in their line of work are very meager.The present study was conducted to assess the knowledge and practice of ethics in their line of work among practicing dentists from various dental colleges in Bangalore, India.A descriptive cross-sectional survey was conducted among 258 practicing dentists attached to various dental colleges in Bangalore city of Karnataka, India. Independent sample t-test was used to compare the knowledge and practice scores according to gender and qualification. One way ANOVA was used to compare knowledge and practice score according to practice type and practice period.Mean knowledge score among males is 8.9 as compared to 9.43 among females and mean practice scores among males was 8.25 as compared to 8.29 in females. Statistically significant differences were found in the mean knowledge and practice scores among graduate dentists and specialists. Mean knowledge score among graduate dentists was 8.44 as compared to 9.36 among specialists and mean practice scores among graduate dentists was 7.7 as compared to 8.53 in specialists.A significant association between the knowledge and practice scores was observed, implying that with an increase in knowledge, there was also an increase in the practices of ethics among study population.

Vascular anomalies are amongst the most common congenital abnormalities observed in infants and children. Their occurrence in the head and neck region is a source of functional and aesthetic compromise. This article reviews the surgical management of 115 cases of vascular anomalies involving the head and neck area treated by the authors between 1998 and 2009. It discusses the diagnostic aids, treatment protocol and the results obtained. A new classification based on the anatomical location and depth of the lesion has been proposed. This allows guidelines for surgical ablation of the vascular lesions. The complications encountered are discussed. The use of external carotid artery control as opposed to pre-surgical embolization has proved effective and the technique is described. The location and extent of a vascular malformation should dictate the preoperative investigations, surgical procedure and subsequent outcome. © 2011 International Association of Oral and Maxillofacial Surgeons.

Salivary fistula after a traumatic injury in the buccal region is not common. It is most commonly encountered in injuries involving the pre auricular region or soft tissues along the course of the parotid duct. It is more frequent in the parotid because its anatomical location is superficial; traumatic salivary fistulae of the other two major salivary glands are rare. This report presents an unusual case of a salivary fistula that occurred following trauma to the infraorbital region and drained into the inferior fornix of the left eye. A review of cases reported in the literature is presented. This is the only case of such a presentation the authors have found after a thorough search of the relevant English language literature. © 2012 International Association of Oral and Maxillofacial Surgeons.

Asymmetry is a major problem in repaired unilateral cleft lip (UCL). One of the important manifestations of this is the asymmetry of the vermilion. The aim of this study was to correlate the severity of the asymmetry in the vermilion to the size of the alveolar defect. Twenty patients aged between 6 and 18 months with complete unilateral cleft lip, alveolus, and palate were included. An impression of each patient's alveolus at the time of cheiloplasty was taken using silicon rubber base material, and a study cast was prepared. The width of the cleft alveolus was measured on these casts using a transparent grid. Frontal photographs were taken at 6 months postoperative and vermilion symmetry was measured as the ratio between the cleft and non-cleft sides. The results obtained in this study showed a direct correlation between the size of the alveolar defect and the vermilion symmetry in repaired UCL. The wider the cleft alveolus and greater the antero-posterior discrepancy, the greater is the vermilion asymmetry. The asymmetry of the vermilion in UCL after repair is directly dependent on the size of the alveolar defect. The alveolar discrepancy causes 'in-rolling' of the vermilion on the cleft side and affects the vermilion symmetry. © 2016 International Association of Oral and Maxillofacial Surgeons.

This case report is of a rare occurrence of necrotic ulcerative changes in a female patient with Fanconi's anaemia and its successful periodontal management. The response of the periodontium to certain genetic and haematological disorders may vary from bleeding, ulcerations and necrosis to a more severe form of periodontitis. Periodontal management in such conditions still remains an enigma with respect to the timing of the periodontal intervention with regard to the systemic wellbeing of the patient. Necrotising ulcerative lesions in a patient with Fanconi's anaemia (FA) progressed rapidly in a week's time necessitating early preliminary periodontal care, which included scaling and root planning using ultrasonic equipment supplemented with hydrogen peroxide irrigation, in conjunction with systemic antibiotics and blood transfusion. Following 1 unit (500ml) of fresh whole blood transfusion 24 hours preoperatively, basic periodontal therapy, comprising of removal of necrotic slough and thorough scaling was done. There was marked resolution of the necrotic ulceration and related symptoms when the patient was followed up for a period of 1 month. This report reconfirms most oral manifestations of Fanconi's anaemia and is the first of its kind to associate necrotic ulcerative changes of the gingiva with FA. It also goes a step further to emphasise the clinical significance of multidisciplinary approach towards successful patient management, which was the primary objective.

Aims: This prospective study was undertaken to evaluate the contrast enhanced computed tomography (CECT) criteria in detecting cervical lymph node metastasis in 50 patients with an oral squamous cell carcinoma (OSQCC). Materials and Methods: A total of 50 patients with OSQCC who underwent clinical assessment, routine CECT scanning of cervical lymph node and radical neck dissection were analyzed. Radiologic criteria for diagnosing nodal metastasis in this imaging study were: A nodal size of 1 cm, the presence of central lucency despite the size of the lymph node and grouping of lymph nodes. These criteria were based on modified American Joint Committee on Cancer Radiological Nodal Staging Guidelines. Statistical Analysis: Chi-square test/Fisher Exact test has been used to find the significant association of findings. Diagnostic statistics viz.: Sensitivity, specificity, positive predictive value (PPV), negative predictive value, and diagnostic accuracy were obtained. The results were considered significant when P value was less than 0.05. Results: On using a nodal size of 1 cm and the presence of central nodal necrosis (CNN) as radiological criteria for nodal metastasis CT scanning staged 23 of the 27 histopathologically positive necks, providing accuracy of 88%, sensitivity of 92%, and specificity of 84% in detection of nodal metastasis. A significant relationship between the incidence of CNN, different nodal densities, and primary tumor differentiation was observed. Conclusions: The nodal size cut-off of 1-1.5 cm had a maximal sensitivity of 90.91% and PPV of 86.96%. Furthermore, observation of nodal densities in the absence of frank CNN on the CT scan may be necessary especially in low grade primary tumor. CT assessment of cervical node metastasis was found acceptable, although adjuncts like ultrasound guided fine needle aspiration may further increase efficacy of CT scan in nodes lesser than 1 cm in size.

Cerebral palsy (CP) is described as a group of conditions usually occurring in childhood, where children have motor dysfunction and are unable to adequately master the necessary techniques of plaque control, which ultimately leads to dental caries and periodontal problems.The objective of this study was to educate the parents/caretakers/institution staff and children with CP about the different preventive home care measures and to evaluate the oral hygiene and gingival health status of these children before and after the institution of different preventive home care measures.A total of 64 individuals with CP, aged between 6 and 18 years, were examined for their oral hygiene and gingival health status, after which the parents/caretakers received a health education program. The children were then randomly divided into four groups. Each group was administered a specific preventive home care measure (mechanical and chemotherapeutic) to be followed for a period of 6 weeks, and the oral hygiene and the gingival health status were recorded at the end of 1 week, 2 weeks, and 6 weeks. The data were then subjected to statistical analysis.In the sample of 64 children diagnosed with CP, the mean OHI(S) score among the groups of children who were given different preventive home care measures was compared at baseline, 1 week, 2 weeks, and 6 weeks. Group 4 showed a marked reduction in the OHI(S) score measured from baseline to 6 weeks, when compared to the other three groups which wa statistically very highly significant (P < 0.001) The mean MGI score was compared at baseline, 1 week, 2 weeks, and 6 weeks home, Group 4 showed a marked reduction in the MGI score measured from baseline to 6 weeks, when compared to the other three groups. When the mean MGI score was compared from baseline to 6 weeks, there was a gradual decrease in the MGI score, which was statistically highly significant between baseline and 1 week (P < 0.05) and statistically very highly significant between 1 and 2 weeks (P < 0.001). However, this improvement was not statistically significant between 2 and 6 weeks (P > 0.05).A combined mechanical and chemotherapeutic measure is highly recommended to maintain the oral hygiene and gingival health of these special children because of their difficulties and their limited abilities to control dental plaque.

A manifold increase in the consumption of aerated beverages has witnessed a twin increase in tooth wear and raised demand for esthetic restorative materials. This study aimed to evaluate the surface microhardness changes of esthetic restorative materials following treatment with aerated beverages in an in-vitro situation.The initial surface microhardness of the restorative materials GC Fuji II LC, GC Fuji IX, Nano Glass ionomer, Resin and Nano composite was recorded. These materials were studied under 3 groups that included those exposed to the acidic beverages daily, weekly once in a month and those that had no exposures at all. The final surface microhardness of the materials was recorded following experimentation and was subjected to statistical comparisons.The restorative materials were compared for their surface microhardness changes following respective treatments using the T-test and One-way ANOVA analysis. Inter-comparisons between the groups showed statistical significance (p<.05), when treated with both the beverages. The five restorative materials revealed surface microhardness loss; the maximum reduction noticed with the Nano glass ionomer cement tested (p<.0005).The surface microhardness of restorative materials markedly reduced upon repeated exposures with acidic beverages; the product with phosphoric acid producing the maximum surface microhardness loss.Restorative materials, acidic beverages, surface microhardness, resin composites, glass ionomers.

This study compared digital two-dimensional (2D) lateral cephalograms and cone-beam computed tomography (CBCT) total and half-skull images for the reliability of cephalometric measurements.(1) To compare the accuracy of cephalometric measurements and reproducibility between the digital and CBCT cephalograms in the Indian population. (2) To compare interobserver variability in landmark identification through their cephalometric measurements by comparing different imaging modalities (CBCT total skull, CBCT half-skull, and conventional lateral cephalogram). (3) To further compare half-skull with the total skull synthesized CBCT and digital cephalograms in the same regard.Thirty patients, who had consented with orthodontic treatment, participated in the study. Informed consent was obtained from the patient before the radiographic procedures. 2D digital lateral cephalograms and their corresponding CBCT scans were taken and imported in DICOM format to OnDemand 3D software. Twenty-three landmarks were identified by 3 observers and 9 linear and 14 angular measurements were digitally traced. The values were sent for statistical analysis using ANOVA to check the interobserver reliability between the imaging modalities.ANOVA, Students t-test, and post hoc test were used for the statistical analysis.The interobserver reliability was high between the modalities. CBCT total skull received an overall intraclass correlation coefficient (ICC) value of 0.76. The ICC value for the CBCT half-skull was 0.79 and for the digital cephalograms it was 0.80. The reliability for CBCT total skull was marginally less when compared to the CBCT half-skull and digital cephalograms, but more for the mid-sagittal measurements. Digital cephalograms showed the most variation with measurements of the mandibular plane when compared to CBCT.CBCT has the potential to be used for cephalometrics, especially the half-skull images, but further studies are required to prove whether CBCT total skull images can be used. 2D cephalometry, however, still does remain as the mainstay of orthodontic diagnosis and treatment planning and cannot be easily replaced by three-dimensional cephalometry.

It is a well-established fact that in squamous cell carcinoma cases, the presence of lymph node metastases decreased the 5-year survival rate by 50% and also caused the recurrence of the primary tumor with development of distant metastases. Till date, the predictive factors for occult cervical lymph nodes metastases in cases of tongue squamous cell carcinoma remain inconclusive. Therefore, it is imperative to identify patients who are at the greatest risk for occult cervical metastases. This study was thus performed with the aim to identify various histopathologic parameters of the primary tumor that predict occult nodal metastases.The clinicopathologic features of 56 cases of lateral tongue squamous cell carcinoma with cT1NoMo/cT2NoMo as the stage and without prior radiotherapy or chemotherapy were considered. The surgical excision of primary tumor was followed by elective neck dissection. The glossectomy specimen along with the neck nodes were fixed in formalin and 5 urn thick sections were obtained. The hematoxylin & eosin stained sections were then subjected to microscopic examination. The primary tumor characteristics that were analyzed include tumor grade, invading front, depth of tumor, lymphovascular invasion, perineural invasion and inflammatory response. The nodes were examined for possible metastases using hematoxylin & eosin followed by cytokeratin immunohistochemistry.A total of 12 cases were found with positive occult nodal metastases. On performing univariate analysis, the histopathologic parameters that were found to be statistically significant were lymphovascular invasion (p = 0.004) and perineural invasion (p = 0.003) along with a cut-off depth of infiltration more than 5 mm (p = 0.01).Histopathologic assessment of the primary tumor specimen therefore continues to provide information that is central to guide clinical management, particularly in cases of occult nodal metastases. Clinical significance The study highlights the importance of extensive histopathological screening, which holds the key for establishing occult metastases. Pathological upgrading of tumors is possible following histopathological studies similar to the present one. Presence of occult metastases justify neck dissection in these clinically N0 cases. In an Indian setting, histopathological evaluation assumes a bigger role than other expensive and advanced techniques.
