"Journal of Clinical and Diagnostic Research is at present a well-known Indian originated scientific journal which started with a humble beginning. I have been associated with this journal since many years. I appreciate the Editor, Dr. Hemant Jain, for his constant effort in bringing up this journal to the present status right from the scratch. The journal is multidisciplinary. It encourages in publishing the scientific articles from postgraduates and also the beginners who start their career. At the same time the journal also caters for the high quality articles from specialty and super-specialty researchers. Hence it provides a platform for the scientist and researchers to publish. The other aspect of it is, the readers get the information regarding the most recent developments in science which can be used for teaching, research, treating patients and to some extent take preventive measures against certain diseases. The journal is contributing immensely to the society at national and international level."

" Journal of Clinical and Diagnostic Research (JCDR) is a multi-specialty medical and dental journal publishing high quality research articles in almost all branches of medicine. The quality of printing of figures and tables is excellent and comparable to any International journal. An added advantage is nominal publication charges and monthly issue of the journal and more chances of an article being accepted for publication. Moreover being a multi-specialty journal an article concerning a particular specialty has a wider reach of readers of other related specialties also. As an author and reviewer for several years I find this Journal most suitable and highly recommend this Journal."

"It gives me great pleasure to be associated with JCDR, since last 2-3 years. Since then I have authored, co-authored and reviewed about 25 articles in JCDR. I thank JCDR for giving me an opportunity to improve my own skills as an author and a reviewer.
It 's a multispecialty journal, publishing high quality articles. It gives a platform to the authors to publish their research work which can be available for everyone across the globe to read. The best thing about JCDR is that the full articles of all medical specialties are available as pdf/html for reading free of cost or without institutional subscription, which is not there for other journals. For those who have problem in writing manuscript or do statistical work, JCDR comes for their rescue.
The journal has a monthly publication and the articles are published quite fast. In time compared to other journals. The on-line first publication is also a great advantage and facility to review one's own articles before going to print. The response to any query and permission if required, is quite fast; this is quite commendable. I have a very good experience about seeking quick permission for quoting a photograph (Fig.) from a JCDR article for my chapter authored in an E book. I never thought it would be so easy. No hassles.
Reviewing articles is no less a pain staking process and requires in depth perception, knowledge about the topic for review. It requires time and concentration, yet I enjoy doing it. The JCDR website especially for the reviewers is quite user friendly. My suggestions for improving the journal is, more strict review process, so that only high quality articles are published. I find a a good number of articles in Obst. Gynae, hence, a new journal for this specialty titled JCDR-OG can be started. May be a bimonthly or quarterly publication to begin with. Only selected articles should find a place in it.
An yearly reward for the best article authored can also incentivize the authors. Though the process of finding the best article will be not be very easy. I do not know how reviewing process can be improved. If an article is being reviewed by two reviewers, then opinion of one can be communicated to the other or the final opinion of the editor can be communicated to the reviewer if requested for. This will help one’s reviewing skills.
My best wishes to Dr. Hemant Jain and all the editorial staff of JCDR for their untiring efforts to bring out this journal. I strongly recommend medical fraternity to publish their valuable research work in this esteemed journal, JCDR".

"I wish to thank Dr. Hemant Jain, Editor-in-Chief Journal of Clinical and Diagnostic Research (JCDR), for asking me to write up few words.
Writing is the representation of language in a textual medium i e; into the words and sentences on paper. Quality medical manuscript writing in particular, demands not only a high-quality research, but also requires accurate and concise communication of findings and conclusions, with adherence to particular journal guidelines. In medical field whether working in teaching, private, or in corporate institution, everyone wants to excel in his / her own field and get recognised by making manuscripts publication.

Authors are the souls of any journal, and deserve much respect. To publish a journal manuscripts are needed from authors. Authors have a great responsibility for producing facts of their work in terms of number and results truthfully and an individual honesty is expected from authors in this regards. Both ways its true "No authors-No manuscripts-No journals" and "No journals–No manuscripts–No authors". Reviewing a manuscript is also a very responsible and important task of any peer-reviewed journal and to be taken seriously. It needs knowledge on the subject, sincerity, honesty and determination. Although the process of reviewing a manuscript is a time consuming task butit is expected to give one's best remarks within the time frame of the journal.
Salient features of the JCDR: It is a biomedical, multidisciplinary (including all medical and dental specialities), e-journal, with wide scope and extensive author support. At the same time, a free text of manuscript is available in HTML and PDF format. There is fast growing authorship and readership with JCDR as this can be judged by the number of articles published in it i e; in Feb 2007 of its first issue, it contained 5 articles only, and now in its recent volume published in April 2011, it contained 67 manuscripts. This e-journal is fulfilling the commitments and objectives sincerely, (as stated by Editor-in-chief in his preface to first edition) i e; to encourage physicians through the internet, especially from the developing countries who witness a spectrum of disease and acquire a wealth of knowledge to publish their experiences to benefit the medical community in patients care. I also feel that many of us have work of substance, newer ideas, adequate clinical materials but poor in medical writing and hesitation to submit the work and need help. JCDR provides authors help in this regards.
Timely publication of journal: Publication of manuscripts and bringing out the issue in time is one of the positive aspects of JCDR and is possible with strong support team in terms of peer reviewers, proof reading, language check, computer operators, etc. This is one of the great reasons for authors to submit their work with JCDR. Another best part of JCDR is "Online first Publications" facilities available for the authors. This facility not only provides the prompt publications of the manuscripts but at the same time also early availability of the manuscripts for the readers.
Indexation and online availability: Indexation transforms the journal in some sense from its local ownership to the worldwide professional community and to the public.JCDR is indexed with Embase & EMbiology, Google Scholar, Index Copernicus, Chemical Abstracts Service, Journal seek Database, Indian Science Abstracts, to name few of them. Manuscriptspublished in JCDR are available on major search engines ie; google, yahoo, msn.
In the era of fast growing newer technologies, and in computer and internet friendly environment the manuscripts preparation, submission, review, revision, etc and all can be done and checked with a click from all corer of the world, at any time. Of course there is always a scope for improvement in every field and none is perfect. To progress, one needs to identify the areas of one's weakness and to strengthen them.
It is well said that "happy beginning is half done" and it fits perfectly with JCDR. It has grown considerably and I feel it has already grown up from its infancy to adolescence, achieving the status of standard online e-journal form Indian continent since its inception in Feb 2007. This had been made possible due to the efforts and the hard work put in it. The way the JCDR is improving with every new volume, with good quality original manuscripts, makes it a quality journal for readers. I must thank and congratulate Dr Hemant Jain, Editor-in-Chief JCDR and his team for their sincere efforts, dedication, and determination for making JCDR a fast growing journal.
Every one of us: authors, reviewers, editors, and publisher are responsible for enhancing the stature of the journal. I wish for a great success for JCDR."

"On looking back through my Gmail archives after being requested by the journal to write a short editorial about my experiences of publishing with the Journal of Clinical and Diagnostic Research (JCDR), I came across an e-mail from Dr. Hemant Jain, Editor, in March 2007, which introduced the new electronic journal. The main features of the journal which were outlined in the e-mail were extensive author support, cash rewards, the peer review process, and other salient features of the journal.
Over a span of over four years, we (I and my colleagues) have published around 25 articles in the journal. In this editorial, I plan to briefly discuss my experiences of publishing with JCDR and the strengths of the journal and to finally address the areas for improvement.
My experiences of publishing with JCDR: Overall, my experiences of publishing withJCDR have been positive. The best point about the journal is that it responds to queries from the author. This may seem to be simple and not too much to ask for, but unfortunately, many journals in the subcontinent and from many developing countries do not respond or they respond with a long delay to the queries from the authors 1. The reasons could be many, including lack of optimal secretarial and other support. Another problem with many journals is the slowness of the review process. Editorial processing and peer review can take anywhere between a year to two years with some journals. Also, some journals do not keep the contributors informed about the progress of the review process. Due to the long review process, the articles can lose their relevance and topicality. A major benefit with JCDR is the timeliness and promptness of its response. In Dr Jain's e-mail which was sent to me in 2007, before the introduction of the Pre-publishing system, he had stated that he had received my submission and that he would get back to me within seven days and he did!
Most of the manuscripts are published within 3 to 4 months of their submission if they are found to be suitable after the review process. JCDR is published bimonthly and the accepted articles were usually published in the next issue. Recently, due to the increased volume of the submissions, the review process has become slower and it ?? Section can take from 4 to 6 months for the articles to be reviewed. The journal has an extensive author support system and it has recently introduced a paid expedited review process. The journal also mentions the average time for processing the manuscript under different submission systems - regular submission and expedited review.
Strengths of the journal: The journal has an online first facility in which the accepted manuscripts may be published on the website before being included in a regular issue of the journal. This cuts down the time between their acceptance and the publication. The journal is indexed in many databases, though not in PubMed. The editorial board should now take steps to index the journal in PubMed. The journal has a system of notifying readers through e-mail when a new issue is released. Also, the articles are available in both the HTML and the PDF formats. I especially like the new and colorful page format of the journal. Also, the access statistics of the articles are available. The prepublication and the manuscript tracking system are also helpful for the authors.
Areas for improvement: In certain cases, I felt that the peer review process of the manuscripts was not up to international standards and that it should be strengthened. Also, the number of manuscripts in an issue is high and it may be difficult for readers to go through all of them. The journal can consider tightening of the peer review process and increasing the quality standards for the acceptance of the manuscripts. I faced occasional problems with the online manuscript submission (Pre-publishing) system, which have to be addressed.
Overall, the publishing process with JCDR has been smooth, quick and relatively hassle free and I can recommend other authors to consider the journal as an outlet for their work."

Rehabilitation of patients with maxillofacial defects is a difficult task. The denture fabrication for such a patient becomes extremely difficult due to the unavailability of attached keratinized supporting tissues. Pre-prosthetic plastic reconstructive surgery with or without implant therapy may improve denture retention and stability. But this treatment option sometimes cannot be accomplished because of the complexity of surgical reconstruction and the patient’s unwillingness to undergo further surgical interventions. Prosthetic rehabilitation alone, without plastic-surgical reconstruction for an edentulous patient who has undergone segmental mandibulectomy, is a challenging task.


hemimandibulectomy defect, overdenture, guiding flange

Neoplasms which are associated directly or indirectly with the mandible usually require surgical removal of the lesion and extensive resection of the bone (1),(2). Smaller lesions which are removed without discontinuity of the bone are relatively simple, to restore with a prosthesis. Larger lesions that extend into the floor of the mouth may be more difficult to restore with a prosthesis, even though the continuity of the mandible is maintained.(3) Success of the edentulous mandibular resection prosthesis is related directly to the amount of the remaining bone and soft tissue.(4),(5),(6),(7).Segmental mandibulectomy results in special physiological and aesthetic problems(8). Frequently, the edentulous mandible requires reconstructive plastic surgery to create a buccal or lingual sulcus depth to provide a favourable attached tissue foundation for an acceptable mandibular denture.(10) After reconstructive surgery, implant-assisted overdentures may improve denture retention and stability. Most of the patients with malignant neoplasms also undergo radiotherapy after resection surgery to limit the metastasis. Radiotherapy complications worsen the success of reconstructive surgical intervention as well as implant therapy. (11),(12) At the same time, patients also become reluctant to undergo multiple surgical interventions. Some patients cannot afford such treatment. Without preprosthetic reconstructive surgery, denture fabrication for mandibulectomy patients becomes extremely difficult. An associated complication of the hemimandibulectomy resection is the deviation of the mandible to the resected side.

Case Report

A 69-year-old, man was referred to the Department of Prosthodontics in our dental hospital with the chief complaint of difficulty in eating and speaking. The patient gave a history of a tobacco smoking habit since 25 years. He was diagnosed with squamous cell carcinoma of the left buccal mucosa about 2 years back. His medical history revealed that he had undergone segmental mandibulectomy in the left posterior region, partial glossectomy, and modified radical neck dissection 18 months back. The resultant defect was reconstructed with free fibular autogenous bone graft. The patient received a postoperative course of total 7200 cGy external beam radiation for 6 months to limit neck metastasis. Intraoral examination revealed thick, freely movable soft tissue with scar formation, the loss of the alveolar ridge and the obliteration of the buccal and the lingual sulcus in the entire left half of the mandibular region [Table/fig 1] . The patient was edentulous, except for the mandibular right lateral incisor and canine which remained, but with poor periodontal support and grade I mobility. There was a completely edentulous alveolar ridge present on the right half of the mandible. The scarring of the tissue after surgery caused severe deviation of the mandible to the resected side. The patient complained of inability to eat and wanted restoration of the missing teeth. Rehabilitation was planned with fabrication of a tooth supported overdenture to aid in retention and stability of the denture on the resected mandible and a conventional complete denture with a guiding flange attached to the maxillary denture to guide the closure of mandible into proper occlusion on the non-resected side.

Due to resection of the left side of the mandible, closing the jaws in proper occlusion and mastication was extremely difficult due to the deviation of the mandible to the resected side. The complete denture treatment described in this report indicated that a guiding flange attached to the opposing denture could significantly improve the patient’s control and closure of the jaws and thereby, greatly improve occlusion and mastication.

Root canal treatment of the mandibular right lateral incisor and canine were carried out after proper scaling and root planning. The teeth were prepared to receive a cast post and a metal coping (Table/Fig 2). The improvement of the crown to root ratio greatly decreased the mobility of the teeth and helped to maintain the remaining bone height, which was very necessary to provide retention and stability for the denture, especially after the resection. A sectional elastomeric impression was made to make a die foe fabrication of the metal posts with copings on the prepared teeth (Table/Fig 3) . The cast metal copings with the posts were cemented with GIC (Table/Fig 4) . The glass ionomer cement provides the advantage of fluoride release and thereby, gives protection against carries. The patient was called for the impressions, 24 hrs after the cementation. The primary impression for the edentulous maxilla was made in medium fusing impression compound (Y-Dents impression compound; MDM Corporation, New Delhi, India), with the help of stock edentulous tray, from which the primary cast was made (Table/Fig 5). The custom tray was fabricated, carefully border molded and the final impression was made with Zinc oxide eugenol paste (DPI Impression paste, Dental products of India, Mumbai, India). Mandibular diagnostic impressions were made in irreversible hydrocolloid material (Dentalgin; Prime dental products, Mumbai, India). Mandibular custom tray was fabricated with autopolymerizing acrylic resin (DPI Cold Cure; Dental products of India, Mumbai, India). The trays were carefully border molded and then, the final mandibular impression was made with elastomeric impression. The impressions were poured with type III gypsum material (Kalstone; Kalabhai Karson Pvt. Ltd., Mumbai, India) to make the final cast. The final maxillary and mandibular casts were obtained and the wax rims were prepared. The position of the mandibular record base was evaluated and modified in the mouth until stability during functional movements was achieved. The shape of the wax rim was modified using the neutral-zone technique [14,(15).Orientation jaw relation was recorded and transferred to the semi adjustable articulator (Hanau H2; Teledyne Technologies, Los Angeles, Calif) (Table/Fig 6) . Vertical and horizontal jaw relations were recorded and transferred to the articulator and the mandibular cast was mounted on the articulator. The deviation of the mandible made it difficult to record the horizontal relation, nevertheless, the mandible was guided to proper relation with the maxilla and the relation was sealed and transferred onto the articulator. The semi-adjustable articulator was used to simulate opening/closing arc of the mandible onto the articulator and to achieve the balanced occlusion, only on the right eccentric movements. However, it was important to maintain the same relation after insertion, but the mandibular deviation was a problem and thereby, it was decided to fabricate a guiding flange attached to the maxillary denture, which would guide the mandibular denture into occlusion and prevent mandibular deviation. The mandibular path into proper occlusion was recorded in wax, which was extended from the palatal surface of the maxillary trial denture base. The wax was softened and the patient was guided to slowly close into proper occlusion(Table/Fig 7) . This was repeated for a few times till it was confirmed that the wax guided the patient to properly close the mandible into proper relation on the non-resected side without any deviation to the resected side without assistance. The occlusion was checked in the patient’s mouth (Table/Fig 8) . Proper closure was confirmed with the coinciding of the maxillary and mandibular midlines (Table/Fig 9) (Fig-9). Anatomic acrylic resin denture teeth (Acryrock; Ruthinium, Badia Polesine, Italy) were arranged and it was decided to try and arrange teeth on the resected side, also to help in balancing the tooth contacts on the non resected side. But during the try-in, it was evident that the patient was uncomfortable with the tooth contacts on the resected side and though he was instructed not to bite on the teeth on the left side (resected side), he was not able to control the movements of the mandible and could damage the tissues covering the defect. As limited denture supporting area was available on the defect side, the teeth were arranged only upto the second premolar. The trial dentures were tried in the patient’s mouth and were evaluated for denture stability during speech and eccentric jaw movements. The dentures were processed in heat polymerizing acrylic resin (Lucitone 199, Dentsply Intl) according to the conventional technique(Table/Fig 10) (16). The efficacy of the guiding flange to guide the closure of the mandible into proper occlusion was evaluated (Fig-11) (Table/Fig 10) . During insertion to improve the tissue contact situation, resilient liner (PermaSoft Denture Liner; Dentsply Austenal, York PA) was used to reline the mandibular denture by keeping the mandible into the maximum intercuspation position (Fig-12,13) (Table/Fig 10). The sealer was applied once over the polymerized surface of the resilient liner, which prevents water sorption by the liner and helps in maintaining the softness for a longer period of time (17). The dentures were checked in the patient’s mouth for function, phonetics, aesthetics and comfort and instructions were given for proper denture care and maintenance. The patient was recalled after 3 days. After fifteen days of denture delivery, the patient was allowed to eat soft diet only from the right side. The patient’s satisfaction level was evaluated, after one month of denture use, according to the method described by Loney et al (18). The patient was asked to rate his comfort in terms of a percentage where he had indicated about 90 percent of satisfactory level. He was pleased with the improved masticatory and aesthetic outcome. He was followed further at a regular interval of 2 months, for the first 1 year, to examine his adaptability to the denture and his satisfaction level.

The peripheral borders, tooth position and external contours of the dentures greatly affect and influence the stability of the dentures. The forces developed through muscular contraction during mastication, speaking and swallowing are directed against the dentures. Proper border extension of the denture, correct denture polishing surface contours and balancing occlusal contacts should be achieved for denture retention and stability.


With the loss of the buccal and lingual sulcus and the presence of scar tissue, denture stability was extremely difficult to achieve in this case. Moreover, the mandibular deviation to the resected side is a hindrance in obtaining denture stability and occlusion. In this case, the deviation was controlled by the addition of a guiding flange (23) to the maxillary denture, which significantly improved the patient acceptance and denture stability and provided proper occlusal contacts. Displacement of the scar by the denture base also needed to be avoided. However, to achieve denture stability, proper border extension of the denture and correct denture polishing surface contours were harnessed. In patients with unfavourable edentulous tissue support, the neutral zone impression technique is recommended to register the soft tissue contour and the denture polished surface (14),(19). The soft tissues that form the internal and external surfaces of the denture greatly affect and influence the stability of the dentures, and help in determining the peripheral borders, tooth position, and the external contours of the dentures (15). The forces developed through muscular contraction during mastication, speaking and swallowing are directed against the dentures (20) These either helps to stabilize or dislodge them (21) The conventional treatment plan for complete dentures described in this report indicated that though the denture bearing tissues were unfavourable; the polished surface, occlusal surface and tissue surface were carefully modified to give a favourable denture stability. The occlusion could easily be adjusted in the mouth when the base was stable and the jaw closure performance was correct. The patient was instructed to chew only on the non-resected side, to avoid denture instability (22). It may be necessary to accept an occlusion that is not bilaterally balanced in eccentric occluding positions for an edentulous resected maxilla or mandible (24). In this patient, the occlusal table on resected side was upto the second premolar, just to establish the cross arch stability and balance in the right lateral excursive movements. The patient was instructed to avoid chewing from the left (resected/defect) side.

Changes in tissues beneath a maxillofacial prosthesis may be more rapid than in those beneath an ordinary complete prosthesis. Therefore, the occlusion and base adaptation was reevaluated frequently (24). Denture base adaptation was maintained by changing the resilient liner every year.


Prosthetic rehabilitation alone, without plastic-surgical reconstruction for an edentulous patient who has undergone segmental mandibulectomy, is a challenging task. The denture bearing tissues were unfavourable and there was a problem with the deviation of the mandible to the resected side. Simple use of the guiding flange and the neutral zone concept can help in achieving a satisfactory prosthesis for such patients. Application of conventional prosthodontic principles, along with patient cooperation, can achieve long term success of the prostheses and predictable patient satisfaction in such complex cases.
