Introduction: During orthodontic treatment, temporary anchoring devices (TADs) are used to restrain tooth movement. They are a relatively recent addition to the dental toolkit. Aim: As TADs have limitations, Dr. Eric Lieu of Taiwan developed Infra Zygomatic Crest (IZC) screws which are placed between the maxillary second premolar at the bony crest. Treatment Planning: The goal of this case study is to emphasize the value of anatomy, site selection, and IZC retrieval in the event of an accident. Cone beam computed tomography was used as a diagnostic tool for the precise location of the displaced IZC and immediate surgical retrieval was done under local anesthesia from the infratemporal space to prevent further complications. Take-away Lessons: Orthodontists knowledge of soft tissue and hard tissue anatomy and precise positioning is crucial for successful TAD implantation.

Context: The city of Chennai is one of the largest metropolitan cities in India where apart from a large traditional population, there has been a continuous migration from rural areas and growing sophistication in lifestyle. Twinning rates trend in the present world would be interesting to study. Aims: The aim of the present study was to analyse the twinning rate in the city of Chennai, the distribution amongst various city zones and the present trends in the co-relation between the maternal age of the twins with the zygosity. Settings and Design: A population-based study was conducted on twin births in various corporation Zones in the Chennai Metropolitan, between 2010 and 2012. As per the Chennai corporation and Health Department register, there were a total of 2,32,884 births registered in the city of which 4,500 were twin births over the 3 years. Only 1371 pairs were found residing in Chennai at the time of study, and hence, a study was conducted on this population only. Statistical Analysis Used: The data were analysed with Epiinfo software. Results: A twining rate of 19.3 per 1000 births was observed as per Corporation records. In the present study, the sample of 150 pairs, 34 pairs (22.6%) comprised of monozygotic (MZ) twins and 116 pairs (77.3%) comprised of dizygotic twins giving a ratio of 1:3. The maternal age groups 25–30 and 30–35 years comprised of the maximum twinning rates. Most twin births were of the first order. An analysis of Weinberg's Differential Rule method to determine zygosity showed a significant difference compared to the Questionnaire method. Conclusions: The twinning rate observed in Chennai in the present study is interestingly very high, compared to the overall twinning rate reported in the past in the state of Tamilnadu. The Wienberg's Differential method for zygosity determination is again found to be questionable. The zygosity proportion, maternal age and parity relations are not very different from previously available data.

Purpose: The negligence of oral health combined with barriers in accessing adequate oral care is more commonly encountered in children with sensory deficits. In a developing country like India, there is a severe lacuna in data regarding the oral health status and treatment needs in this group of population. The purpose of this study is to assess the oral health status and treatment needs of children with sensory deficits, using WHO criteria of Basic Oral Health Survey Methods, 1997. Materials and Methods: A descriptive cross-sectional study was conducted using the WHO criteria (Basic Oral Health Survey, 1997); questionnaire data regarding the demographic profile, oral hygiene status, degree of sensory impairment were recorded and tabulated. The Chi-square test was used to determine whether there existed a significant difference in the oral health status. The confidence interval was set at 95% and alpha error was assumed at 0.05. Results: Among the 742 sensory deficit children examined, 371 children are visually impaired and 371 are hearing impaired. Gingival bleeding and poor oral hygiene is diagnosed in more than 70% of the visually impaired children. The prevalence of trauma is estimated to be 8% in children, who are visually impaired. In the hearing impairment group, gingival bleeding because of inadequate oral hygiene is seen in 58% of the population examined. There is no statistically significant difference in the dental caries status between visually impaired and hearing impaired children (P > 0.05). There is also no statistically significant difference in the restorative treatment need and trauma status between visually impaired and hearing impaired children (P > 0.05). Conclusion: The present study shows a high prevalence of gingival diseases and dental caries in the special health care group children. The study signifies a wide spread presence of unmet treatment needs among children in this study population.

Background: Conflict is an inevitable and integral part of any work environment including nursing. Unresolved conflicts among nurses may lead to increased errors in patient care, affect their morale, and even increase turnover. Objective: The objective of the study is to determine the conflict-handling styles practiced by newly joined nursing staff working in a tertiary care hospital. Materials and Methods: This descriptive cross-sectional study was conducted on newly joined 297 nurses. Standardized Thomas-Kilmann Conflict Mode Instrument was used to collect the data. Nurses were asked to give answers that characterized their dominant response in a conflict situation. Results: A total of 34.7% nurses used accommodating style for conflict management whereas 30.3% used collaborating style. It was followed by compromising, competing, and avoiding styles of conflict management. Conclusion: There is a need to enhance nurses' conflict management skills which in long run may lead to improvement in the quality of work as well as job satisfaction among nurses.
