Implant Insertion Torque Load Analysis for Mandible using CBCT Images
Authors: Venkatakrishnan CJ 
Published: June 2017

ABSTRACT

Introduction
Osteoporotic patients require particular attention to their implant site bone quality as an indication of prognosis and may require modified surgical technique Insertion Torque (IT).

Aim
It is the purpose of this study to test whether IT is significantly correlated with bone density or not, as assessed by the cone-beam computed tomography (CBCT) in a group of osteopenic and osteoporotic patients.

Materials and methods
A total of 30 patients were included in the study. The mandibular second premolar region was chosen as the site of investigation to prevent variability in surgical implant placement technique in different locations affecting bone mineral density (BMD). Partially, edentulous female patients between 51 and 60 years of age who were scheduled to receive implant placement were recruited for the study. CBCT (Master Series 3D Dental Imaging) was used for preoperative evaluation of the jaws for each patient. Materialise's Interactive Medical Image Control System (MIMICS) was used to process stacks of 2D images from CBCT. Finite element analysis were carried out on bone using Ansys software. Maximum displacement and maximum stress—strain patterns were compared in normal, osteoporotic, and osteopenic groups.

Results
The difference in mean bone density in all three groups were statistically significant (p < 0.05) (Table 1). FEA at 32, 36, 40 N in all 3 groups was statistically significant. (Table 2).

Conclusion
Within the limitations of the study, the amount of stress—strain that exhibits at 40 N load in normal bone will be almost the same stress—strain given at 32 N load in osteoporotic bone. Normal IT load analysis exhibits more stress/strain in osteoporotic patients when compared with other groups, showing that IT must be achieved to an optimum level to avoid further complication and failures.

Authors: Darout Ismail A 
Published: June 2017

ABSTRACT

Aim
This study was designed to evaluate knowledge and awareness toward orthodontic treatment among treated subjects as compared with untreated subjects and to correlate the communications between treated subjects and their practicing orthodontists.

Materials and methods
Self-reported questionnaires were distributed to be completed by the consent subjects. They were 340 untreated subjects (220 males and 120 females) and 102 subjects (57 males and 45 females) who recently received orthodontic treatment in the age range 19 to 28 years. Subjects that received orthodontic treatment were selected among the attendees of clinics of College of Dentistry, Jazan University, Kingdom of Saudi Arabia. The data were analyzed using Statistical Package for the Social Sciences (version 21, Institute Inc., USA).

Results
Subjects who received orthodontic treatment scored higher mean of total scores of awareness 14.74 and knowledge 11.18. The difference of awareness and knowledge between treated and untreated subjects was highly significant (p = 0.000). The female treated subjects scored higher than male treated subjects in attitude toward thumb sucking as a cause of malocclusion (91.3 and 70.2% respectively). Early primary teeth extraction as a cause of malocclusion was scored by 76.1% females and 42.1% males. The male treated subjects show significant (p > 0.05) correlation between the total items of knowledge of orthodontic treatment and total items of orthodontist—patient communications.

Conclusion
Orthodontic treated subjects have more knowledge and awareness about orthodontic treatment than untreated subjects. A significant association was found between communications and knowledge of orthodontic treatment in male as compared with female patients.

Clinical significance
Knowledge and awareness toward orthodontic treatment and the communications of orthodontic patients with treating orthodontist can significantly increase the orthodontic treatment outcome.

Authors: de Molon Rafael S 
Published: June 2017

ABSTRACT

Aim
The aim of this case report was to reconstruct the alveolar buccal bone plate lost in consequence of a root fracture in the maxillary central incisor area after immediate implant placement (IIP). A 48-year-old patient was referred to our office with the chief complaint of spontaneous bleeding in his left central incisor. After careful examination, the following comprehensive treatment approach was carried out: (1) Atraumatic tooth extraction, (2) IIP, (3) provisional prosthesis installation, (4) alveolar buccal bone plate reconstruction with autologous bone collected from the maxillary tuberosity, (5) gingival augmentation procedure with connective tissue graft removed from the palate, and finally (6) adjustment of the provisional restoration. After 1-year postoperative, an adequate esthetic outcome was achieved with lower cost, reduced morbidity to the patient, and lower treatment time. This approach was able to improve gingival architecture and bone volume with adequate thickness and width, enhancing patient esthetics and satisfaction. In conclusion, when proper diagnosis, precise surgical techniques, and appropriate multidisciplinary approach are employed, IIP followed by immediate dentoalveolar restoration might be considered a safe procedure to restore the peri-implant bone and gingival recession favoring the achievement of appropriate esthetic outcomes.

Clinical significance
The treatment planning employed was able to improve gingival architecture and bone volume with sufficient width and thickness enhancing patient esthetics and satisfaction in one single-stage procedure.

Assessment of Root Resorption and Root Shape by Periapical and Panoramic Radiographs: A Comparative Study
Authors: Bhardwaj Atul , Ahuja Puneeta D , Mhaske Sheetal P , Mishra Gaurav , Dwivedi Ruby 
Published: June 2017

ABSTRACT

Introduction
One of the common findings encountered by the clinician at the end of orthodontic treatment is the apical root resorption. Root resorption occurs to various degrees. A severe form of root resorption is characterized by shortening of root for more than 4 mm or more than one-third of the total tooth length. A low incidence rate of resorption is observed based on radiographic findings for the diagnosis of root resorption, panoramic radiography, and periapical radiography. Hence, we evaluated the accuracy of panoramic radiographic films for assessing the root resorption in comparison with the periapical films.

Materials and methods
This study included the assessment of all the cases in which pre- and post-treatment radiographs were available for analysis of the assessment of the amount of root resorption. Complete records of 80 patients were analyzed. Examination of a total of 900 teeth was done. Mean age of the patients in this study was 21 years ranging from 11 to 38 years. The majority of the patients in the present study were females. All the treatments were carried out by registered orthodontists having minimum experience of more than 10 years. All the cases were divided into two study groups. Group I comprised panoramic radiographic findings, while group II consisted of periapical radiographic findings. For the measurement of crown portion, root portion, and the complete root length, magnification loops of over 100 powers with parallax correction with inbuilt grids were used. Assessment of the tooth length and the crown length was done by the same observers. All the results were analyzed by Statistical Package for the Social Sciences software version 6.0.

Results
Maximum amount of root resorption was observed in case of maxillary central incisors and canines among group I and II cases respectively. However, nonsignificant difference was obtained while comparing the mean root resorption in relation to maxillary incisors and canines among the two study groups. While comparing the overall value of root resorption among the two study groups, a significant difference was obtained. The maximum value of tooth length in both the groups was observed in cases of maxillary canines. Significant differences were observed while comparing the tooth length of various teeth among the two study groups. Among the deviated forms of root shape, dilaceration was the most common form of root shape detected in both the study groups.

Conclusion
Periapical radiographs are more efficient in the assessment of the shape and resorption of the root.

Clinical significance
Thorough evaluation of periapical radiographs is necessary for detection of even minute levels of root resorption.

Authors: Suresh S , Markose Joji , Eshwar Shruthi , Rekha K , Jain Vipin 
Published: June 2017

ABSTRACT

Introduction
Comparison of platform switched (PS), sloping shoulder, and regular implants on stress reduction in various bone densities with finite element analysis.

Materials and methods
A total of 12 three-dimensional finite element models were built to analyze the stress distribution model. Nobel Biocare 4.3 × 8 mm regular platform replace select implant with matching diameter easy abutment, Nobel Biocare 4.3 × 8 mm replace select implant PS with 3.5 mm diameter easy abutment, Bicon 4 × 8 mm implant with 4 mm diameter sloping shoulder abutments were created virtually in compact bone density using software. The 130 N axial force and a 90 N oblique loading force were applied to the abutment to analyze the stress.

Results
Under horizontal and vertical loading, the sloping shoulder implant had lesser stresses in cancellous bone when compared with PS and regular implants. Sloping shoulder implant showed more stress distribution at implant–abutment interface and at crestal area, whereas with regular implants, the stresses were distributed at cortical area.

Conclusion
Sloping shoulder implant in subcrestal position is much favorable for bone growth, stress distribution, and preservation of remaining bone.

Clinical significance
Use of sloping shoulder implant design distributes the stress apically and creates lesser stresses when compared with PS implants.

Endodontic Management of Dilacerated Maxillary Central Incisor fused to a Supernumerary Tooth using Cone Beam Computed Tomography: An Unusual Clinical Presentation
Authors: Vinothkumar Thilla S , Kandaswamy Deivanayagam , Arathi Ganesh , Ramkumar Sathishkumar , Felsypremila Gnanasekaran 
Published: June 2017

ABSTRACT

Aim
The purpose of this report is to present a case of endodontic management of a dilacerated maxillary central incisor fused to supernumerary tooth unusually appearing as a labial tubercle using cone beam computed tomography (CBCT) as a diagnostic aid.

Background
Anterior teeth are commonly encountered with aberrant anatomical variations in the crown, number of roots, and root canals. Fusion is an infrequent developmental abnormality in shape of the tooth caused by the union of two adjacent tooth germs. A complete knowledge of such complex anatomies is mandatory for a successful root canal treatment. It highlights the endodontic and restorative approach in the functional and esthetic rehabilitation of the involved tooth.

Case report
Three-dimensional imaging using CBCT was used in this case to differentiate single labial canal and palatal C-shaped canal. The endodontic treatment was performed with the aid of dental operating microscope, and the root canals were obturated with a combination of single cone, carrier based, and cold flowable gutta-percha obturation system. The tooth remained asymptomatic without reinfection and symptoms of failure for 18 months.

Conclusion
Cone beam computed tomography is indispensable in treatment planning for cases where the radiographs cannot reveal useful information regarding the root canal shape. Postobturation CBCT has helped in avoiding further retreatment of the tooth, which otherwise is a challenging task.

Clinical significance
The use of sophisticated equipment, such as dental operating microscope and CBCT has helped in accurate diagnosis and treatment planning of fused central incisor respectively.

A Randomized Controlled Trial of Extra-amniotic Saline Infusion vs Intracervical Dinoprostone Gel for Induction of Labor
Authors: Rodrigues Steffi V , Swamy MK , Jadhav Namrata 
Published: June 2017

ABSTRACT
Background
Success of induction depends largely on cervical ripening and increases the likelihood of vaginal delivery. This study compared the outcomes for induction of labor using extra-amniotic saline infusion (EASI) vs intracervical dinoprostone gel.

Objective:
Primary: To compare improvement between pre- and post-induction Bishop’s scores in both the groups.
Secondary: To compare induction to delivery interval, mode of delivery, and neonatal outcome in both the groups.

Materials and methods
A randomized controlled trial of 1 year was conducted in the Department of Obstetrics and Gynaecology, Karnataka Lingayat Education University Dr Prabhakar Kore Hospital and Medical Research Centre, Belagavi, Karnataka, India, on 82 pregnant women from January 2014 to December 2014. The selected women were divided into two groups of 41 each as group I (induced with dinoprostone) and group II (induced with EASI using Foley’s catheter).

Results
Significantly higher number of women had postinduction Bishop’s scores between 9 and 12 in the dinoprostone group (70.73%; p < 0.001). The mean Bishop’s scores were significantly high in the dinoprostone gel (9.27 ± 3.07) vs EASI (8.22 ± 2.34; p = 0.086). Cervical ripening based on cut-off score of ≥6 was noted in a significantly higher number of women (92.68%) in EASI (p = 0.241). The mean time for cervical ripening was significantly high in dinoprostone gel group compared with EASI (15.44 ± 8.41 vs 3.88 ± 3.67; p < 0.001), but mean induction to delivery time was comparable (p = 0.086). Significantly higher numbers of vaginal deliveries were noted in dinoprostone group (91.43%; p = 0.001). The neonatal outcomes, i.e., birth weight, mean birth weight, appearance, pulse, grimace, activity, and respiration score at 1 and 5 minutes, and neonatal intensive care unit admission, were comparable (p = 0.570).

Conclusion
Dinoprostone gel and EASI using Foley’s catheter appear to be effective methods for cervical ripening and labor induction, but dinoprostone gel yielded significantly higher rate of vaginal delivery.

Authors: Singh Sonam 
Published: June 2017

ABSTRACTObjectiveTo assess the feasibility and outcome of laparoscopic myomectomy and multiple-layer closure of myoma bed for management of myomas at a tertiary care hospital.Materials and methodsFive hundred and ten patients from January 2011 to January 2017 with large and moderate size myomas were managed by laparoscopic myomectomy. Indications were subfertility, menorrhagia, and abdominal mass. Preoperative evaluation included history, clinical examination, and sonographic mapping. Myomas were enucleated and retrieved laparoscopically. Myoma beds were sutured in multiple layers by endoscopic intracorporeal suturing. Fluid as adhesion barrier was used.ResultsThree hundred and eighty two patients presented with subfertility, 69 with menorrhagia, and 59 with abdominal mass. The average maximum diameter of myoma was 9.1 cm. The mean duration of surgery was 90 minutes. The mean postoperative stay was 24 hours. No intraoperative complication occurred and the hospital course was uncomplicated. In seven cases, minilap incision was given for retrieval of myoma and suturing of the bed. Two patients had minor delayed wound healing of the morcellator port site. The patients did not report any complaints during follow-up except one patient who developed omental hernia at morcellator port site. There was no rupture of scar and very low adhesion scores in subsequent cesarean sections or second look scopies.ConclusionWith proper multilayer closure of the myoma bed, laparoscopic myomectomy is feasible for moderate and even large myomas and has good outcomes in terms of fertility and alleviation of symptoms.How to cite this articleJain N, Singh S.

Bartholin Gland Endometriosis
Authors: Singh Sonam 
Published: June 2017

ABSTRACT
Endometriosis is a commonly encountered benign gynecological disease, involving extrauterine growth of both endometrial glands and elements of endometrial stroma. Like ectopic endometrial tissue, these ectopic foci are susceptive to cyclic hormonal changes. A case of endometriosis infiltrating the Bartholin gland is presented. The initial diagnosis was a Bartholin gland cyst. The clinical diagnosis was made during the operation when chocolate-colored material poured into operation field, and histopathologic examination confirmed the presence of endometriosis. Bartholin gland endometriosis should be kept in mind when women of reproductive age have a diagnosis of Bartholin cyst. It is a rare case and only few cases are reported in the literature.
