Prophylactic antibiotics after extraction: Needed or not needed?
M Deepa, Deepthi Mony, Tusha Ratra
November-December 2017, 9(6):265-268
Aim: Our study aimed to evaluate the need to prescribe antibiotics before every extraction even in healthy individuals. Materials and Methods: A prospective, randomized clinical trial was done on 483 patients who were indicated for undergoing extraction under local anesthesia. The patients were evaluated for signs of infection that included pain, edema, fever, pus discharge, erythema, and decreased interincisal opening. They were evaluated on the 1st, 3rd, and 7th postoperative day for the same. The patient was considered to have an active infection if they showed pain and any other two signs of infections. Statistical Analysis: Descriptive and inferential statistical analysis has been carried out in the present study. Results: Out of the 483 patients evaluated two patients had pain and showed slight edema and erythema. These patients were considered as having an active infection and were prescribed therapeutic antibiotics. Conclusion: In our study, 0.4% showed signs of active infection after undergoing extraction without prophylactic antibiotics. Further studies have to be undertaken to create definitive guidelines for prescribing antibiotics after extraction.

Ansu Kuruvila, Suja Joseph, Namratha L Jayalekshmi, Sujith K Menon
May-June 2017, 9(3):136-139
Pier abutment poses a challenge to prosthodontist. Rigid connectors are less than ideal treatment in case of these abutments. Nonrigid connectors have been recommended to reduce the forces as they provide a stress-breaking effect. This case report presents an alternative approach to the management of pier abutment. A 46-year-old female patient with missing teeth involving a pier abutment was rehabilitated with a fixed dental prosthesis with key-keyway connectors. An alternative method of orientation of the connector was used to benefit the patient.

Renjith George, Renu Sarah Samson, Htoo Htoo Kyaw Soe, Preethy Mary Donald, Wang Liang Hui, Pang Khai Ling, Kalpana Saseendran
May-June 2018, 10(3):115-120
Aims: To assess oral health-related quality of life (OHRQoL) in patients with malocclusion and to measure the association of OHRQoL with orthodontic treatment need. Materials and Methods: The study sample comprised 290 participants aged 13 to 30 years, attending orthodontic clinics at the Faculty of Dentistry, Melaka Manipal Medical College (MMMC). The participants were asked to complete the Oral Health Impact Profile-14 (OHIP-14), after which clinical examinations were conducted to assess normative orthodontic treatment needs using the Dental Health Component (DHC) of the Index of Orthodontic Treatment Need (IOTN). Results: A total of 290 adolescent and young adults participated in this study. The mean overall score for OHIP-14 was 11.8(±8.0). There was no significant association of oral health related quality of life (OHRQoL) between different age groups, gender, ethnicities and education levels. There was no significant association between age, gender, ethnicity, education level and orthodontic treatment need. Also, there was no significant association of OHIP-14 score between no treatment need and little treatment need. However, OHIP-14 score was significantly higher in borderline treatment need compared to no treatment need (6.06, 95% CI 1.07, 11.04), little treatment need (3.95, 95% CI 1.75, 6.16) while high treatment need had significantly higher OHIP-14 score than borderline treatment need (7.13, 95% CI 3.46, 10.80). Conclusion: Malocclusion has a significant negative impact on OHRQoL. There is a significant association in mean overall OHIP score when comparing high orthodontic treatment needs and with no treatment needs. This study did not find any significant association in orthodontic treatment needs in relation to age groups, gender, ethnicities and education level.

AlHanouf Abdullah AlHabdan
July-August 2017, 9(4):141-145
The advancement of restorative materials and techniques continues to enhance the clinical success of numerous restorative procedures. Despite these new innovations, microleakage persists as one of the main causes of restoration failure. Microleakage tests provide useful information on the performance of restorative materials, and different techniques for assessing microleakage have been developed and used. These tests include the use of dyes, radioactive isotopes, air pressure, bacteria, neutron activation analysis, and artificial caries. However, little has been done to determine the cause, mechanism, and nature of microleakage. Therefore, this review outlines and discusses the currently available microleakage assessment tools.

GERT index: A modified tooth mobility and treatment index
Lakshmi Puzhankara
January-February 2018, 10(1):4-9
Aim: Tooth mobility has always been a monumental factor in determining the prognosis of a tooth. There are no indices that link the etiology, grade of mobility, and radiographic appearance with treatment options for mobile teeth. This particular article aims to overcome the oversight and bring in a scoring system that incorporates all the above mentioned components. Materials and Methods: Previously existing index for tooth mobility has been modified (G Score) to make it more defined numerically and clinically, and it has been combined with indices for etiology (E Score) of tooth mobility and radiographic appearance (R Score) of mobile teeth. The Grading Etiology Radiographic appearance (GER) scores have then been allied with a combination of treatment methods (T Score) to get the Grading Etiology Radiographic appearance Treatment (GERT) index. Results: The index that results from this combination is one that encompasses the factors that determine the prognosis and treatment aspects of a mobile tooth. The index given in this article takes into consideration the components that contribute to the diagnosis of the etiology of tooth mobility such the clinical presentation and the radiographic appearance. The grade of mobility has been modified to allow for precise numerical assessment of mobility. Thus, the treatment plan proposed considers the basic cause for the mobility and the comprehensive treatment modality for the same. Conclusion: Although the index appears elaborate, once mastered, it would pave the way for a thorough treatment planning for mobile teeth and efficient execution of the treatment plan.

MM Sunil, MA Zareena, MS Ratheesh, G Anjana
March-April 2017, 9(2):88-90
Single tooth anterior crossbite is commonly seen in the early mixed dentition period. Once identified, the treatment should ideally involve any method which is simple, noninvasive, involves little chair side time, requires minimal patient cooperation, and gives rapid correction of the crossbite without affecting the surrounding structures. In young children, compliance with a removable appliance can often be an issue. Here, we present a fixed appliance for the correction of single tooth anterior crossbite in mixed dentition using a simple appliance.

Ramprasad Vasthare, Santhosh Kumar, Lim Yan Ran Arron
March-April 2018, 10(2):71-76
This literature review was done to estimate the uses and effectiveness of carbon monoxide (CO) breath analyzers in identifying smokers and evaluating the role it can play in tobacco cessation programs. A web-based research on PubMed and Scopus from date of inception till 2016 was done for collecting data for the review. Our inquiry was limited to relevant articles with specific keywords. During the web search title and abstracts, 118 articles were screened for content and quality and 66 articles were selected to get an update on the desired information. As on date, there is enough evidence to prove the reasonably high sensitivity and specificity of CO analyzers in distinguishing smokers and nonsmokers. It also correlates well with smoking status. Its primary application is in validating smoking abstinence and as a motivational tool in smoking cessation programs. Due to its advantages over other biochemical assays, it is used in screening large population, in developing countries and in research. It can also detect pregnant women who are smokers and victims of passive tobacco exposure. However, it does possess limitations which have to be taken into account when using it. It can be concluded that CO analyzers are proven to have great potential and can be used as an adjunct in achieving the goal of combating tobacco addiction. It is cheap, noninvasive, gives immediate results, easy to use, and it can be self-administered by individuals. It should henceforth be considered as an invaluable tool for tobacco cessation programs.

Shrinkage in composites: An enigma
Dhakshinamoorthy Malarvizhi, Arumugam Karthick, NewBegin Selvakumar Gold Pearlin Mary, Alagarsamy Venkatesh
September-October 2019, 11(5):244-248
In recent years, increased demand for perfectly aesthetic restoration coupled with improved performance of composite resin made clinicians to select composite resins over amalgam restoration. Patients prefer composite restoration not only for restoring anteriors but also to replace their unaesthetic amalgam restoration of their posteriors. The greatest limitation of composite resin as posterior restoration is its polymerization shrinkage leading to marginal leakage, tooth or restoration fracture, postoperative sensitivity, ultimately leading to the reduction of the long-term success of the restoration. There are several factors associated with the polymerization process that have its impact on the integrity of the tooth restoration complex. So the astute clinician should have thorough knowledge regarding the mechanism involved in polymerization shrinkage and the techniques of overcoming it. The objective of this article was to make the clinician understand the factors and the problems related to the polymerization shrinkage with the methods to overcome the same for the clinical longevity of the restoration.

September-October 2019, 11(5):249-255
Aims and Objectives: To investigate the oral health effects of using toothpaste containing granular calcium carbonate (CaG). Materials and Methods: The subjects were adult volunteers. Two kinds of toothpaste, Paste P and Q were used. Paste P contained 13% CaG, which had a mean diameter of 250 µm and a breaking strength of 20 gf. Paste Q had the same formulation without CaG. Study 1 was to evaluate the ability to remove dental plaque by toothpaste with a single use, and it was a crossover study. The subjects were 50 adults. Plaque levels were assessed using the Quigley–Hein Index (QHI). Study 2 was to investigate the effects of CaG in toothpaste on gingival health. The subjects were 60 adults. The subjects used Paste P for 3 days before the baseline assessment. On the baseline assessment, the subjects whose gingival sulci were found to contain CaG were asked to continue using the Paste P for 6 months. The pocket depth, the gingival index (GI), the QHI, and the presence of CaG in the gingival sulci at 1, 3, and 6 months from the baseline were examined. Results: In study 1, the CaG-containing toothpaste produced a significantly lower mean QHI than the control. In study 2, the QHI and GI of the gingival sulci in which CaG was detected were significantly lower than those of the gingival sulci in which CaG was not detected. Conclusion: Toothpaste containing CaG removed greater amounts of plaque and did not have adverse effects on periodontal tissue.

Various recent reinforcement phase incorporations and modifications in glass ionomer powder compositions: A comprehensive review
Arbaz Sajjad, Wan Zaripah Wan Bakar, Dasmawati Mohamad, TP Kannan
July-August 2018, 10(4):161-167
Glass ionomer cements (GIC) were first introduced to dentistry in the late 1960s and since have proven to be useful in various areas of dental science, particularly restorative dentistry. As an aqueous polyelectrolyte system, GICs are known for their relative ease of use, chemical bond to the tooth, fluoride release and recharge, low coefficient of thermal expansion, and acceptable esthetic quality. However, clinical usage of GICs is still limited due to their relatively inferior mechanical properties and sensitivity to initial desiccation and moisture. Years of extensive research on enhancing the chemistry of the basic glasses have yielded improved formulations with enhanced mechanical properties and reduced moisture sensitivity. A comprehensive review of the available literature has revealed that not all modifications in glass powder have resulted in the desirable strengthening of GICs. There is a shift of focus toward studies on nanoscale particles and bioactive glass. Recent research has proven that incorporation of nanoceramics such as hydroxyapatite (HA), fluorapatite, silica, and zirconia (ZrO2) have resulted in improved mechanical properties of GICs due to their ability to release fluoride, high surface area, and better particle size distribution. More work should thus, be undertaken to optimize techniques for enhancing the physicomechanical properties of GICs by incorporation of nanophases of ZrO2, HA, and metallic nanofillers.

March-April 2017, 9(2):65-70
Background: Selection of approach to treat orbital fractures involves multiple factors such as visibility and esthetics. Aims and Objectives: The aim of this study is to compare subciliary and infraorbital incisions for orbital floor and infraorbital rim fractures. Materials and Methods: We carried our study in twenty patients, who reported to the department of oral and maxillofacial surgery with orbital floor and infraorbital rim fractures. The patients were divided into two groups (Group A - subciliary incision and Group B - infraorbital incision), with ten patients in each group. We compared infraorbital and subciliary incisions to approach the infraorbital rim and orbital floor in orbital fractures using criteria such as exposure time, esthetics, and complications. Results: All the analysis was done using SPSS version 14.P < 0.05 was considered statistically significant. We found that infraorbital incision took shortest time for exposing fractured site, caused more edema after 1 month of procedure, and lead to more visible scarring when compared to subciliary incision. Conclusion: We recommend subciliary incision to approach the infraorbital rim and orbital floor fractures.

Aim: To analyze the association between functional oral health literacy (FOHL) and oral health behaviors with periodontal disease among adults with type 2 diabetes mellitus (T2DM). Materials and Methods: A cross-sectional analysis study was conducted among 1110 adults with T2DM who were selected by multistage random sampling from 10 hospitals of five provinces in the northeast region of Thailand. A structured questionnaire was developed, and face to face interview and also clinical oral examination and blood glucose investigation were carried out. Data distribution was performed by descriptive statistic and chi-square test. The multiple logistic regression was used to determine the association between variables after adjustment for confounders. Results: In this study, a total of 1110 adults with T2DM divided into two groups according to the severity of periodontal disease showed 51.89% of moderate–severe periodontal disease. The study examined the association of periodontal disease with the independent variables after adjusted odd ratios, it was found to be statistically significant with the FOHL level (adjusted odds ratio [AOR] = 1.80, 95% confidence interval [CI] = 1.30–2.40), toothbrushing frequency (AOR = 1.73, 95% CI = 1.24–2.40), smoking (AOR = 2.25, 95% CI = 1.45–3.40), and betel nut crewing (AOR = 2.13, 95% CI = 1.28–3.45). Moreover, the demographic characteristics of patients with T2DM associated with the severity of periodontal disease in variables of gender, age, education level, duration with diabetes, and health insurance were also statistically significant at P < 0.05.

July-August 2018, 10(4):176-179
Aims: The purpose of this in situ study was to compare the effects of nanohydroxyapatite or eggshell (ES) extract on the microhardness of healthy third molar tooth enamel following soft drink exposure. Materials and Methods: This study was performed as a randomized clinical trial. This experimental study was conducted with ten participants and involved twenty extracted, healthy, permanent third molar teeth. The initial microhardness values of the teeth were measured. The teeth were then exposed to delestre for 10 min, and the microhardness was measured again. Samples were divided into two groups of 10. For each appliance, two teeth were placed, one from each group and one on either side of the appliance. For the in situ study, sections of two teeth, one from each group, were embedded in an appliance and placed in the mouth of the volunteer. Each volunteer used this appliance for 10 days. After 10 days, the microhardness of the teeth was measured again. Finally, data were analyzed using analysis of variance and paired t-tests. Results: The mean tooth enamel microhardness was significantly decreased following exposure to delestre and the mean microhardness of demineralized tooth enamel significantly increased after exposure to both nanohydroxyapatite and eggshell extract. Conclusion: Nanohydroxyapatite and ES have the potential to remineralization erosive lesions.

September-October 2018, 10(5):237-243
Aims: Probiotics have been proven to be beneficial for general and systemic health. Many in vitro and in vivo studies have investigated the use of probiotics for the prevention or treatment of dental caries and gingival diseases. Lactobacillus reuteri is believed to possess anti-microbial and anti-inflammatory properties. The aim of our randomized controlled trial was to evaluate the effect of chewing gums containing probiotics and xylitol on the salivary Streptococcus mutans counts, plaque, and gingival scores after the intervention. Materials and Methods: In our 3-week, short-term trial, 40 healthy 7–12-year-old children consumed two commercially available chewing gums; Group 1 (BioGaia™ ProDentis) and Group 2 (Orbit®Gum, Wrigley's). Individuals consumed three chewing gums daily, immediately after major meals for 20 min each. The probiotic gum contained two strains of L. reuteri (ATCC 55730 and ATCC PTA 5282) along with artificial sweetener, sorbitol, and the xylitol gum consisted of both xylitol and sorbitol. Pre- and post-intervention whole unstimulated saliva samples were collected and cultured on Mitis Salivarius Bacitracin agar plates to check for colony forming units/ml of Streptococcus mutans. Plaque and gingival scores were also recorded at pre- and post-intervention appointments. Results: Following the intervention, the salivary Streptococcus mutans counts decreased in both groups. There was a significant reduction in plaque and gingival scores at postintervention examination. Conclusion: Probiotics can be used as an alternative to xylitol in the preventive regimen for dental caries or control in case of high caries risk.

March-April 2017, 9(2):81-87
Aims and Objectives: To evaluate the knowledge, attitude, and perception (KAP) of dental students toward ionizing radiation, biological hazards, and appropriate radiographic protection methods. To assess the need for improving the knowledge/awareness toward radiation hazards and protection methods among the dental students and interns. Materials and Methods: A cross-sectional questionnaire study was conducted. A total of 174 dental students who had completed their 30 days posting in Department of Oral Medicine and Radiology were inducted for the study. All the students were subjected to structured 17 response questionnaire with multiple choices. Data collected were subjected to statistical analysis using the SPSS software package version 17. Pearson Chi-square test was done to evaluate the statistical significance. Results: The present study revealed 54.22% correct response from 3rd year followed by 57.78% from final years and 61.64% from interns. The overall correct response was 57.57%. Conclusion: The results from the present study revealed that the KAP level in regard to the biological hazardous effects of X-ray and protection was low to average among dental students. It is recommended that the syllabus of dental radiology should be expanded to provide clinical knowledge regarding radiation hazards and protection, so that students are well grounded with the principles of dental radiography.

March-April 2018, 10(2):63-70
Traumatic head injuries (THIs) associated with maxillofacial fractures (MFFs) are large public health concern worldwide, especially among adult-aged males. The MF injuries accompanied with THI involve serious esthetic and functional problems that lead to various consequential complications; therefore, early detection of associated THI in patients with MFF is the urgent need for initial assessment and treatment planning because it can reduce morbidity and mortality and enhance the outcome of treatment in those patients. The present review provides current updates for THI associated with MFF among different countries considering the prevalence, age, sex, etiology, and types of MFF in patients with THI throughout the world. The young adult males in the age group of 20–39 years were the most sustained THI associated with MFF. Road traffic accident (RTA) was the most common etiology of injury followed by assault, fall, and the other causes represent very low percentages. The types of MFF (orbital, zygoma, maxilla, and mandible) were associated with THI in MFF patients. Within the limits of the reviewed THI associated with MFF literature, it was concluded that civilization, culture, adult age group, male gender, RTA, and assault were the major factors that determine the trends of THI-related MFF. In this study, we recommend improving public awareness by applying road traffic regulations, encouraging the rules for compulsory use of seat belts and helmet, avoiding risky driving, and enhancing road quality.
