Assessment of minimum force required to initiate sliding of stainless steel wire in ceramic (monocrystalline and polycrystalline) and stainless steel preadjusted edgewise brackets using stainless steel and elastomeric ligation techniques – An in vitro study p. 17

Objectives: To compare the force required to initiate sliding of rectangular stainless steel wire in monocrystalline ceramic bracket v/s polycrystalline ceramic bracket v/s stainless steel bracket using stainless steel ligation technique and to compare the force required to initiate sliding of rectangular stainless steel wire in monocrystalline ceramic bracket v/s polycrystalline ceramic bracket v/s stainless steel bracket using elastomeric ligation technique. Methods: The archwire was pulled in a vertical direction by the testing machine, until the resistance was overcome and the archwire started to slide through the bracket. The force to overcome resistance and to initiate sliding of the archwire was measured. Results: In metal brackets, there is minimum resistance to sliding as compared to the two different ceramic brackets. Among the two ceramic brackets polycrystalline bracket offered more resistance to sliding then monocrystalline bracket. Although SS ligation offered less resistance to sliding then elastomeric ligation in all three bracket types, the difference between the two ligation systems is not statistically significant. Conclusions: In maximum anchorage cases metal bracket along with SS ligation should be used to reduce the frictional resistance, enabling the use of lighter forces and eventually conserving the anchorage.

A cone-beam computed tomographic analysis to evaluate and compare the root thickness of prepared teeth, centering ability, canal transportation, and instrumentation time in the deciduous teeth using Hyflex controlled memory and ProTaper next file systems – An in vitro study p. 22

Objectives: The aim of this study was to evaluate and compare remaining root thickness, centering ability, canal transportation, and instrumentation time of Hyflex controlled memory (CM) and ProTaper (PTN) files in the primary root canals using a cone-beam computed tomographic (CBCT) analysis. Materials and Methods: Fifty freshly extracted human primary teeth with minimum of 7 mm root length were randomly divided into two groups (Group 1 – Hyflex CM files, Group 2 – PTN files) were included in the study. Teeth were scanned using CBCT before and after the instrumentation for both the groups. Remaining dentin thickness, centering ability, canal transportation, and instrumentation time were evaluated for each group. Results: A significant difference was found in remaining root thickness and instrumentation time between Hyflex CM and PTN file system. PTN files showed better remaining root thickness as compared to Hyflex CM files, and the mean instrumentation time of “PTN” was significantly less than “Hyflex CM files.” Conclusions: PTN file system was found to be faster with more remaining root thickness of the primary teeth and hence can be recommended for shaping the root canals of the primary teeth.

Evaluation of the nutritional status of oral submucous fibrosis patients using body mass index and mid-upper arm circumference (anthropometric assessment): A cross-sectional, observational study p. 26

DOI:10.4103/INPC.INPC_15_20  
Background: For a rapid nutritional status of oral submucous fibrosis (OSMF), body mass index (BMI) and mid-upper arm circumference (MUAC) are used in the study.Materials and Methods: The cross-sectional, observational study was conducted among 150 OSMF patients and categorized into four groups according to the functional stages of OSMF. The measurements of BMI and MUAC among all groups were noted, compared, and statistically analyzed.Results: Among 150 patients, BMI and MUAC scores showed a statistically significant difference and highly correlated in all stages of OSMF.Conclusion: In OSMF patients, BMI and MUAC scores were decreased with an increase in severity and stages of OSMF.

Knowledge, attitude, and practice of dentists toward immediate dental implant p. 30
Ujjwal Priyadarsi, Mohammad Shahbaz Alam, Pramod Kumar Singh, Dhrubajwati Sen, Farrukh Azam, Richa S N. Minz
DOI:10.4103/INPC.INPC_21_20  
Background: With the advent of immediate single-stage implant placement, the edentulous patient can receive replacement in the same surgical visit, thereby reducing the time that has elapsed between tooth extraction and implant placement. There is a scarcity of literature that assesses patient's knowledge, attitude, and practice (KAP) of dental students toward immediate implant placement, therefore the need of the study. Materials and Methods: A multiple-choice questionnaire consisting of 12 questions was framed and distributed to dentists between January 2019 and June 2019 from all the dental clinics in Dhanbad, Jharkhand, India, who have entered their clinical practice with the primary objective to determine their KAP toward loading protocols of immediate and delayed implants. Results: Thirty-one percent of the respondents are aware of loading protocols of immediate implants and delayed loading and 69% were not aware of immediate implant procedures. Conclusion: Although dental implants have changed the outlook of dentistry in the past few decades, the knowledge and practice of implants by dental practitioners in Dhanbad is still limited, and there is a need to improve the same.

Coronavirus disease-19 and dentistry p. 33
Prachi Asnani, Mohil Asnani, Nimesh Patel, Mohammed Muzammil Khan, Afreen Kauser, Ashu Soni
DOI:10.4103/INPC.INPC_18_20  
Coronavirus disease 2019 or coronavirus disease, described as a pandemic recently, is a cumulation of respiratory disorders transmitted mainly through droplets from an infected person. Aerosols produced during various dental procedures can cause a high risk of transmission. This report describes measures that can be adopted by oral health-care personnel to minimize the risk of cross-contamination in clinical practice during this severe acute respiratory syndrome corona virus 2 pandemic.

Management of an open apex with mineral trioxide aggregate apexification: A case report p. 36

DOI:10.4103/INPC.INPC_6_20  
Mineral trioxide aggregate (MTA) has the advantage of being less soluble than calcium hydroxide and offers an enhanced seal due to its setting expansion which hermetically seals the pulp space, preventing bacterial contamination from the outside. The use of MTA as an alternative material to calcium hydroxide for apexification has gained popularity. This case report presents the use of MTA as an apical plug for an open apex central incisor with periapical lesion.
