The body fluids such as blood and plasma and urine have always been used as diagnostic tools. However recognition of saliva as a diagnostic tool came much later in the medical/dental scenario. Being non-invasive and cost effective and freely available, saliva can be used for diagnosis of not only oral diseases, but also many systemic diseases. The following paper reviews the use of saliva for diagnosis of various diseases.

Effect of De-Sensitizers on the Retention of Full Veneer Metal Crowns in Tooth Preparations with Varying Tapers -An In vitro Study

[Year:2012] [Month:July-December] [Volume:2] [Number:2] [Pages:6] [Pages No:5 - 10]

Keywords: de-sensitizers, crown-retention, preparation taper

   DOI: 10.5005/jsd-2-2-5  |  Open Access |  How to cite  | 


Background: In addition to the variations in taper of the full crown preparation, application of de-sensitizer may also result in diminished adhesion of adhesive cements to tooth structures. This study evaluated the effect of two commercially available de-sensitizers on the retention of crowns made on standard and tapered tooth preparations. Methods: Thirty freshly extracted maxillary first premolars were embedded in acrylic resin blocks. They were divided into two groups (n=15). Group I: Prepared with 3 degrees taper. Group II: Prepared with 15 degrees taper. Nickel-chromium copings were cast with a loop at the occlusal surface for tensile testing after luting with resin-modified glass ionomer cement [Fujicem]. Each group was assigned to three subgroups [n= 5 each] according to de-sensitizers used prior to luting. Subgroup I: Systemp® de-sensitizer [Ivoclor Vivadent], Subgroup II: Oxalate de-sensitizer [Prime Dental® products Pvt. Ltd.], and Subgroup III: Control [untreated]. One-way Analysis of Variance [ANOVA] was used as the statistical test of significance. Results: In Group I and II, resin-modified glass ionomer cement exhibited greater mean value retention with Systemp de-sensitizer [206.00±8.22 N and 97.00±2.74 N respectively], followed by the control [149.00±4.18 N and 92.00±2. 74 N respectively]. In both, Oxalate de-sensitizer recorded the lowest mean [110.00±3.54 N and 54.00±6.52 N respectively]. Discussion: Following tooth preparation, irrespective of the taper, de-sensitizers not only reduces post-operative tooth sensitivity but also influence the bond strength of the luting agent.

Comparative Evaluation of Carisolv with EDTA and Sodium hypochlorite in Removing the Smear Layer on Radicular Dentine using SEM -An In Vitro Study

[Year:2012] [Month:July-December] [Volume:2] [Number:2] [Pages:8] [Pages No:11 - 18]

Keywords: CarisolvTM, smear layer, scanning electron microscope

   DOI: 10.5005/jsd-2-2-11  |  Open Access |  How to cite  | 


Background: Smear layer is a tough adherent layer on the instrumented radicular dentin composed of organic and inorganic debris. Removing this layer is imperative for disinfection and obturation of root canal. However no single irrigating solution is effective in removal of the smear layer. 5.25% Sodium hypochlorite and 17% EDTA have been proven to remove both the organic and the inorganic portion of the smear layer, when used alternatively. CarisolvTM is chemo mechanical agent in removal ofcaries which consists of0.5% of Sodium hypochlorite and amino acids. This study aims to evaluate the efficacy of CarisolvTM in removing the smear layer when compared with 17% EDTA, 5.25% Sodium hypochlorite and normal saline. Methodology: 80 roots were divided into 4 groups. All roots were prepared by step back technique and irrigated with various solutions. Roots in Group 1 was irrigated with 1 ml of CarisolvTM, in Group 2 with 1 ml of 0.5% Sodium hypochlorite, in Group 3 with 1 ml of 17% EDTA andin Group 4 with lml of saline. All the teeth were sectioned longitudinally and then horizontally to obtain middle and apical third sections. These samples were evaluated with SEM and the photomicrographs were scored according to a 5-point scale. The data was analysed by using chi square test at p< 0.01. Results: CarisolvTM was found to ineffective in removing the smear layer. 17% EDTA and 5.25% Sodium hypochlorite were effective in removal but neither of them removed the layer completely when used.

[Year:2012] [Month:July-December] [Volume:2] [Number:2] [Pages:7] [Pages No:34 - 40]

Keywords: impacted canine, surgical exposure, orthodontic traction, two stage corticotomy, orthodontic appliance

   DOI: 10.5005/jsd-2-2-34  |  Open Access |  How to cite  | 


The permanent canines play a pivotal role in achieving anesthetic smile, functional occlusion and also in establishing the arch form. However, the management of an impacted canine and bringing about its alignment into the arch is often considered to be very challenging because of relapse. The two stage inter-alveolar corticotomy followed by fixed appliance is advocated to minimize the treatment time and reduce the chance ofrelapse. In this article, two case reports are presented, where labially impacted canine of one patient has been managed by orthodontic movement alone and in another patient a combination of inter-alveolar corticotomy and orthodontic movement has been successfully used.

Inflammatory Dentigerous Cyst in Mixed Dentition- An Enigmatic Diagnosis

[Year:2012] [Month:July-December] [Volume:2] [Number:2] [Pages:6] [Pages No:41 - 46]

Keywords: inflammatory follicular cyst, marsupialisation, radicular cyst, mixed dentition

   DOI: 10.5005/jsd-2-2-41  |  Open Access |  How to cite  | 


Odontogenic cysts commonly seen are the radicular cysts and dentigerous cysts. Radicular cysts arising from deciduous teeth are very rare. A Dentigerous cyst may be of two types; the developmental dentigerous cyst which usually occurs in mature, impacted orunempted teeth and the inflammatory dentigerous cyst which is only found in the mixed dentition. The choice of treatment of the inflammatory dentigerous cysts in mixed dentition would be to extract the infected primary teeth and leave the cystic cavity open for drainage, so as to facilitate the spontaneous emption of the badly dislocated permanent teeth. The ossification of the bony defect is also found to occur simultaneously. This paper describes an inflammatory dentigerous cyst that was treated by extraction of the non-vital primary tooth and marsupialisation of the cyst. A seven month follow-up of the treatment is presented.

A Case of “Camouflage”: Aneurysmal Bone Cyst Simulating a Radicular Cyst

[Year:2012] [Month:July-December] [Volume:2] [Number:2] [Pages:4] [Pages No:47 - 50]

Keywords: bone cysts, aneurysmal/diagnosis, mandible/pathology, female, pseudocyst

   DOI: 10.5005/jsd-2-2-47  |  Open Access |  How to cite  | 


Aneurysmal Bone Cyst (ABC) is an uncommon non-neoplastic pseudocyst. It usually affects the long bones, spine and occasionally involves the jaws. Radiographically, ABC may appear as an uniloucular or multilocular radiolucency with expansion and thinning of the surrounding cortical bone. However, due to the lack of a pathognomonic feature of its own, the diagnosis still remains ambiguous. The following is a report of ABC located at the right body of the mandible in an Indian female patient. The lesion initially camouflaged as a simple radicular cyst. Later, ABC was confirmed only with histo-pathological investigation.

Intentional Replantation of Impacted Maxillary Permanent Central Incisor Associated with Compound Odontoma -A Case Report

[Year:2012] [Month:July-December] [Volume:2] [Number:2] [Pages:5] [Pages No:51 - 55]

Keywords: intentional replantation, impacted central incisor, compound odontome

   DOI: 10.5005/jsd-2-2-51  |  Open Access |  How to cite  | 


Knowledge of the normal tooth eruption pattern is essential for the identification and appropriate treatment of missing teeth. A delay between the exfoliation of a deciduous tooth and the eruption ofits permanent successor may be related to a disorder known as dental retention. A case of compound odontoma that had caused delayed eruption of a maxillary central incisor is presented here. The odontoma, a collection of multiple tooth-like structures, was surgically removed and the impacted incisor was replanted in its position with composite resin splint. The healing was uneventful.

Prosthetic Management of a Patient with Ocular Defect with Custom Ocular Prosthesis

[Year:2012] [Month:July-December] [Volume:2] [Number:2] [Pages:5] [Pages No:56 - 60]

Keywords: evisceration, enucleation, exenteration, anaophthalmos, orbital prosthesis

   DOI: 10.5005/jsd-2-2-56  |  Open Access |  How to cite  | 


As loss of an eye has high psycho-social impact on a patient, the main aim in management in such patients is to replace the missing tissues with an artificial prosthesis, not only to restore optimum aesthetics, facial symmetry and function, but also the self-confidence of the patient. These prosthesis are challenging as they try to reconstruct a mobile organ with a nonmobile prosthesis. Treatment includes implants and acrylic eye prosthesis. Although implant eye prosthesis has superior outcome, due to economic factors it may not be advisable for all patients. Therefore a custom-made ocular prosthesis is a viable alternative. This case report explains a custom-made ocular acrylic prosthesis made for an anophthalmic patient.

Comparative Evaluation of Two Commercially Available Polymer Burs for their Efficacy on Dentinal Caries Removal -Split tooth study using Polarized Light Microscopy

[Year:2012] [Month:July-December] [Volume:2] [Number:2] [Pages:4] [Pages No:66 - 69]

Keywords: caries, dentinal, residual caries, polymer bur, step-wise excavation method, polarized light microscopy

   DOI: 10.5005/jsd-2-2-66  |  Open Access |  How to cite  | 


Background: Ultra conservative caries removal now has become an integral part of Minimal Invasive Dentistry. The main objective of deep caries removal is to conserve the tooth structure as well to maintain the integrity of the health of the pulp. Recently burs made of polymers have been proposed as alternatives for metallic burs to selectively remove caries in dentin. Aims: This in vitro, split-tooth, comparative study evaluated the efficacy of two commercially available Polymer burs, namely Poly bur- I (Komet) and Smart prep bur (SS White) for their efficacy in removing deep dentinal carious lesions. The time taken for caries removal was also assessed. Methodology: IO extracted carious mandibular molars were split into buccal and lingual halves. Caries in one half(n= IO) was removed by Poly bur -I (Komet) and in the other half(n= IO) by Smart prep bur (SS white). They were then sectioned in the hard tissue microtome, subsequently manually thinned out and were mounted for evaluation under Polarized Light Microscopy. Results: The qualitative evaluation of the micro graphs revealed that both the polymer burs were equally effective in removing the deep dentinal caries. However the time taken by Poly bur- I was lesser than the Smart prep bur.
