The key to the management of pier abutment: An alternative approach
Ansu Kuruvila, Suja Joseph, Namratha L Jayalekshmi, Sujith K Menon
May-June 2017, 9(3):136-139
DOI:10.4103/jioh.jioh_121_17  
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.

M Deepa, Deepthi Mony, Tusha Ratra
November-December 2017, 9(6):265-268
DOI:10.4103/jioh.jioh_219_17  
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.

MM Sunil, MA Zareena, MS Ratheesh, G Anjana
March-April 2017, 9(2):88-90
DOI:10.4103/jioh.jioh_9_17  
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.

AlHanouf Abdullah AlHabdan
July-August 2017, 9(4):141-145
DOI:10.4103/jioh.jioh_160_17  
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
DOI:10.4103/jioh.jioh_165_17  
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.

May-June 2017, 9(3):133-135
DOI:10.4103/jioh.jioh_131_17  
The aim of this report is to depict the successful management of a discolored central incisor subsequent to endodontic treatment and its follow-up for 1 year. Improper bleaching techniques can lead to cervical resorption and eventual loss of teeth. Management of the discolored endodontically treated tooth can be performed using sodium perborate (SP). A 22-year-old female who had undergone endodontic treatment of the central incisor reported with discolored maxillary central incisor tooth. The case was managed with “walking bleach technique” using SP and water. The case was followed up for 1 year and there was no relapse. Proper selection of bleaching agent and technique had resulted in the conservative and successful management of the case. Appropriate bleaching technique should be selected to manage discolored teeth.

DOI:10.4103/jioh.jioh_4_17  
Introduction: Use of rotary instrumentation for pulpectomy is a recent emerging concept in the field of pedodontics. The objective of this study was to evaluate the knowledge and practice of NiTi rotary instruments' usage in primary teeth by the Indian dentists. Materials and Methods: A self-administrated questionnaire was prepared and pretested and was given to the private practitioners. A total of 100 completed questionnaires were obtained. The data were entered and analyzed for frequency and percentages using Statistical Package for the Social Sciences (SPSS) software version 17. Results: In the present study, about 50% of the practitioners used rotary instrumentation of root canals in primary teeth, of which majority were postgraduates. ProTaper was the commonly used rotary system in primary teeth. The practitioners felt both taper and length of the existing rotary file to be the limitation for its use in primary teeth. Conclusion: From the present study, it is concluded that there is a need for comprehensive education programs to be conducted to increase the awareness and use of rotary files for pulpectomy in primary teeth. In addition, there is a need for an exclusive pediatric rotary system for convenience in using it in children.

DOI:10.4103/0976-7428.201094  
Aims and Objectives: Osseointegrated implants are used in replacement of missing teeth. Survival rate of implant depends on many factors including oral hygiene, implant material used, bone quality, and personal oral habit such as smoking. The present retrospective research was conducted to assess the effect of smoking on survival of dental implant. Materials and Methods: The study participants were selected from all the patients who underwent for dental implant in implant center from 2005 to 2015. For each patient, various information regarding implant characteristics and smoking habits were recorded. The readings were statistically evaluated by SPSS statistical software by IBM version 21 and using Chi-square test at P ≤ 0.01. Results: In our study, the age range of patients was between 30 and 54 years. There were 2142 (57.2%) male and 1579 (42.4%) female participants, in that 72.2% were nonsmokers and 27.7% were smokers. Implant placed more in mandible (2312, 62%) than in maxillary region (1409, 37.8%). From 3721 patients, 3600 were successful and 121 failures. Success of implant was considerably more in nonsmokers than smokers. Implant failure rate was more in smokers with increased frequency and duration of cigarette smoking habit, but it was statistically not significant. In the present study, we have observed 0.049% mobility in smokers compared to 0.007% in nonsmokers. Conclusion: The present study showed that higher risk of implant failure was associated with long term and increased frequency of smoking due to bone resorption.

Ramprasad Vasthare, Santhosh Kumar, Lim Yan Ran Arron
March-April 2018, 10(2):71-76
DOI:10.4103/jioh.jioh_273_17  
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.

DOI:10.4103/jioh.jioh_26_17  
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.

DOI:10.4103/jioh.jioh_18_17  
Use of reverse pull headgear (RPHG) is well advocated and is widely used all over for the early correction of developing Class III malocclusions, mainly in early and late mixed dentition period. Seldom are any articles found, on the use of RPHG in postpubertal girls with Class III facial profiles and anterior open bite. Twinning of teeth usually results from abnormalities in the development of the tooth. Clinically, such a tooth hampers esthetics and the available arch length, which necessitates multidisciplinary intervention. This article reports the successful correction of a 15-year-old girl with Class III profile, anterior open bite and lower incisor twinning.

DOI:10.4103/jioh.jioh_9_18  
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.

Arbaz Sajjad, Wan Zaripah Wan Bakar, Dasmawati Mohamad, TP Kannan
July-August 2018, 10(4):161-167
DOI:10.4103/jioh.jioh_160_18  
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.

Abdulrahman Hesham, Kamran Bokhari Syed, Basem T Jamal, Ali Mosfer Ali Alqahtani, AlHassan Ahmed Ali Alfaqih, Hassan Amer Ali Alshehry, Mohammad Shahul Hameed, Abdel Bagi Mustafa
May-June 2017, 9(3):105-109
DOI:10.4103/jioh.jioh_58_17  
Background: This is a retrospective study design to assess the incidence of oral cancer in the southern region of Saudi Arabia. The study involves three tertiary care centers primarily involved in oral cancer care. Incidence, type, distribution of oral cancer among age group, gender, region, and site are assessed. Materials and Methods: A self-designed questionnaire assessed the incidence of oral cancer over 10 years among patients visiting tertiary care centers in Southern Saudi Arabia. A total of 2850 files were screened. Demographic data included gender, age group, and the region from where the patient represented. The clinical presentation of the lesion, site, bilateral involvement, and histopathological variant was included in the study. Data are presented as frequency tables and percentages. Results: A total of 94 patients presented with oral cancer. The incidence of oral cancer in Southern Saudi Arabia is 3.29%; 44 (46.8%) were female and rest 50 were male (53.2%). Patients from 8 regions of Southern Saudi Arabia presented with oral cancer. Of the 8 regions, patients from Abha had the highest incidence of oral cancer (20.2%). Clinical presentation varied from the ulcer (59.3%), swelling (19%), ulcer and swelling (12%), and swelling of the neck along with ulcer in primary site (9.6%) in descending order. 37.2% of the patients presented with a lesion in the tongue making it the highest prone site. 91.5% of the patients were diagnosed as squamous cell carcinoma followed by 5.3% as verrucous carcinoma and 3.5% as sarcoma. The mean follow was 5.3 years. Conclusion: The incidence of oral cancer in Southern Saudi Arabia is 3.29% over 10 years. This is significantly low when compared to similar studies conducted elsewhere. The lower incidence might be attributed to the absence of habits such as betel chewing, pan masala, and gutkha habits normally seen in India and regions around. The presentation of oral cancer is similar to other regions of the world. Surprisingly, females have an almost similar rate of incidence as males though slightly less. This makes it mandatory to assess the habits such as smoking among females more thoroughly. Tongue remains to be the site with the highest incidence which correlates with similar findings in other regions of the world.

Materials and Methods: Forty specimens of resin composite (Filtek™ P60) material (3M ESPE St. Paul, MN, USA) with 3 mm diameter and 3 mm height were prepared using a plastic mold. The baseline microhardness values of the specimens were recorded using Vickers microhardness tester. The specimens were randomly allocated into four groups, each containing ten specimens as follows - Group I Listerine® (Johnson & Johnson), Group II Colgate Plax®, Group III Freshclor® (Group Pharmaceuticals), and Group IV AloeDent® (Optima, Bradford-Italy). The pH of all mouth rinses was recorded. Then, the specimens were immersed in 20 ml of respective mouth rinses and kept in an incubator at 37°C for 24 h. The change in the microhardness values of the specimens was recorded. The obtained result was subjected to statistical analysis using Wilcoxon signed rank, Kruskal–Wallis, and Mann–Whitney U-tests. SPSS software version 16 and Microsoft Excel version 7 were also used. The level of significance was set at P= 0.05. Results: There was reduction in the microhardness of all the specimens irrespective of the mouthwashes. Group I (Listerine®) showed significant reduction in the microhardness compared to Group II (Colgate Plax®), Group III (Freshclor®), and Group IV (AloeDent®), whereas there was no statistically significant difference between Group III and Group IV. Conclusion: All the mouth rinses showed reduction in surface hardness of the esthetic restorative material. High reduction of surface hardness was shown in Listerine® mouth rinse. There was no statistically significant difference between Freshclor® and AloeDent® mouth rinses.

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.

Introduction: Any quality of life (QoL) assessment tool needs to be validated in the language of the participants to whom it is administered. Several language versions of oral health impact profile-14 (OHIP-14) already exist, for example, in German, Swedish, Hebrew, Chinese, Hindi, and Scottish. The present study has tried to establish a Gujarati version of OHIP-14. This Gujarati version of OHIP-14 would be useful to assess the impact of oral health on QoL of dental patients, who understand Gujarati. Aim: This study aimed to translate and validate the Gujarati version of OHIP-14. Materials and Methods: The original English version of the OHIP-14 was translated using the World Health Organization method (forward-backward translation technique), and then 109 participants were given English as well as Gujarati versions of OHIP-14 questionnaire. Filled questionnaires were collected from the participants and subjected to statistical analysis. Results: All the 14 questions showed no statistically significant difference between the English version of OHIP-14 and the translated Gujarati version of OHIP-14. Results of unpaired t-test (P = 0.103) were not statistically significant. Pearson's correlation coefficient test was 0.990, suggesting that the translated Gujarati version is highly correlated with the original English version. Conclusions: The translated Gujarati version of OHIP-14 is a precise, valid, and reliable instrument for assessing oral health-related QoL among Gujarati population.

Aim: The purpose of this study is to evaluate and compare postcementation sensitivity under Class II composite inlay with three different luting cements. Materials and Methods: A comparative prospective study was carried out in 45 patients age ranged from 18 to 28 years for 2 years, who fulfilled the criteria. Clinically and radiographically, presence of mild initial dental caries on proximal surface of maxillary and mandibular first molar. Tooth preparation for composite inlay was performed and composite inlay restorations were made by indirect technique. Three different luting cements were used for cementation of composite inlay. Cold water test, compressed air test, and biting pressure test were used to measure the tooth sensitivity in this study. Results: As per the findings of this study, there was no significant difference between all the three groups immediately after cementation. We noted a significant difference between Group I and Group III and Group I and Group II and Group II and Group III after 1 and 6 months. Conclusions: Based on the results of this study, we concluded that restorations cemented with self-adhesive resin cements showed least postoperative sensitivity followed by Resin-modified glass ionomer cement (GIC) and GIC has the highest sensitivity at all intervals of time evaluated using different tests.
