A rare presentation of mucocele and irritation fibroma of the lower lip
BN Rangeeth, Joyson Moses, Veera Kishore Kumar Reddy
April-June 2010, 1(2):111-114
DOI:10.4103/0976-237X.68596  PMID:22114395
The effects of chronic local irritation have been seen commonly in the form of fibroma or mucocele in children. We report a nine year old girl with the chief complaint of multiple swellings in the lower lip which was diagnosed both clinically and histologically as fibroma and mucocele. Surgical excision was done under local anesthesia with no post-operative complications. To our knowledge there was no other occurrence, either at the same site or at different locations, involving these two lesions in the oral mucosa.

An altered cast procedure to improve tissue support for removable partial denture
Chandrashekar Sajjan
April-June 2010, 1(2):103-106
DOI:10.4103/0976-237X.68600  PMID:22114393
Free-end saddles are liable to be displaced under occlusal pressure. This is as a result of the displaceability of the mucosa. The altered cast technique is employed to try and prevent this by making an impression of the mucosa under controlled pressure. The metal framework was constructed on a cast produced by a mucostatic impression material. Base plates were then constructed in self-cured acrylics on the framework in the saddle areas, and these are close fitting. Border molding was carried out; impression was made with zinc oxide eugenol impression paste. In the laboratory, the free-end saddle areas on the master cast are sectioned off. The denture is then positioned on the model and the new saddle areas are poured. The resulting model represents the free-end saddle areas under conditions, which mimic functional load. Denture construction then continues as normal. The distribution of loading of the free-end saddles is improved and denture is more stable.

Capillary hemangioma or pyogenic granuloma: A diagnostic dilemma
MM Rachappa, MN Triveni
April-June 2010, 1(2):119-122
DOI:10.4103/0976-237X.68593  PMID:22114397
Pyogenic granulomas and hemangiomas of oral cavity are well-known benign lesions. Although pyogenic granuloma is known to show a striking predilection for the gingiva and capillary hemangioma for lips, check, and tongue, palatal occurrence of these lesions is extremely rare. The clinical diagnosis of such an uncommon occurrence can be quite challenging as they sometimes may mimic more serious lesions such as malignancies. The purpose of this article is to report an unusual case of benign tumor occurring on hard palate which was clinically diagnosed as pyogenic granuloma and histopathologically as capillary hemangioma.

Full-mouth rehabilitation of a case of generalized enamel hypoplasia using a twin-stage procedure
Aswini Kumar Kar, Hari Parkash, Veena Jain
April-June 2010, 1(2):98-102
DOI:10.4103/0976-237X.68601  PMID:22114392
The dilemma confronting many dentists today is that innovations and well-defined specializations have greatly enlarged the treatment realm for tooth preservation as well as tooth replacement. The objectives should be preservation of the remaining tooth structure, restoration of optimum function, esthetics with least invasive procedures, cost effective, and short treatment time. The number of remaining natural teeth is one of the most widely used method for evaluating oral health and the prosthetic treatment of patients with a mutilated dentition. Though the treatment of these patients can be complex, but there are some important principles applicable in most cases. This case report demonstrates a satisfying full mouth rehabilitation using the Hobo and Takayama twin-stage procedure for a patient with esthetically and functionally compromised dentition. The final prosthesis with this twin-stage technique ensured a restoration with a predictable posterior disclusion and anterior guidance in harmony with the condylar path.

Lateral cephalometry: A simple and economical clinical guide for assessment of nasopharyngeal free airway space in mouth breathers
Navneet Grewal, Alkesh V Godhane
April-June 2010, 1(2):66-69
DOI:10.4103/0976-237X.68589  PMID:22114385
Nasopharyngeal obstruction by adenoid enlargement is one of the main causes of mouth breathing. Cephalometric radiographs and rhinomanometric tests to evaluate nasal obstruction have been available for several decades. Various lines and areas have been interpreted by number of investigators to implicate the enlarged adenoid in a casual relationship with mouth breathing and the subsequent effect on vertical facial growth. The aim of this paper is to review lateral cephalometric tracing methods combined with newer Auto-cad surface area measurement program so that assessment of the nasopharyngeal free airway space can be done based on it, before more rigorous ear-nose-throat follow up is needed for the patient.

Soheyl Sheikh, Anil Kumar Bhoweer, Smriti Arya, Gagandeep Arora
April-June 2010, 1(2):83-87
DOI:10.4103/0976-237X.68597  PMID:22114389
Aim: The quantitative aspects of radiation doses to critical organs can help the dental professionals to take the necessary radiation protective measures as deemed necessary and can help the general public to allay radiation exposure fear in dental radiography, if any. Our study determines the surface radiation dose to thyroid and gonads in full-mouth intraoral periapical (IOPA) and maxillary occlusal radiography.Materials and Methods: A total number of 120 subjects participated in the study. The surface radiation dose was estimated to the thyroid gland and the gonads in full-mouth IOPA radiography using 10 IOPA (E speed films) and in maxillary occlusal radiography. The measurements were calculated using a digital pocket dosimeter (PD-4507).Results: The average dose at the thyroid gland level during full-mouth intraoral and maxillary occlusal radiography was estimated to be 10.93 mRads (1.093 Χ 10 -2 mGy) and 0.4 mRads (4.0 Χ 10 -2 mGy), respectively. The average surface radiation dose at the gonadal region during a full mouth intraoral and maxillary occlusal radiography was estimated to be 1.5 mRads (1.5 Χ 10 -2 mGy) and 0.15 mRads (1.5 Χ 10 -3 mGy), respectively. Conclusion: Our results suggest that although the radiation exposure doses to critical organs namely thyroid and gonads is within the safe limits still precautionary measures for these organs are advocated.

Herpes zoster oticus: A rare clinical entity
Shailesh Gondivkar, Viren Parikh, Rima Parikh
April-June 2010, 1(2):127-129
DOI:10.4103/0976-237X.68588  PMID:22114399
Herpes zoster oticus also known as Ramsay Hunt syndrome is a rare complication of herpes zoster in which reactivation of latent varicella zoster virus infection in the geniculate ganglion causes otalgia, auricular vesicles, and peripheral facial paralysis. Ramsay Hunt syndrome is rare in children and affects both sexes equally. Incidence and clinical severity increases when host immunity is compromised. Because these symptoms do not always present at the onset, this syndrome can be misdiagnosed. Although secondary to Bell's palsy in terms of the cause of acute atraumatic peripheral facial paralysis, Ramsay Hunt syndrome, with incidence ranged from 0.3 to 18%, has a worse prognosis. Herpes zoster oticus accounts for about 12% cases of facial palsy, which is usually unilateral and complete and full recovery occurs in only about 20% of untreated patients. The most advisable method to treat Ramsay Hunt syndrome is the combination therapy with acyclovir and prednisone but still not promising, and several prerequisites are required for better results. We present a case of 32-year-old man suffering from Ramsay Hunt syndrome with grade V facial palsy treated effectively with rehabilitation program, after the termination of the combination therapy of acyclovir and prednisone.

Sunitha Jagannathachary, Shobha Prakash
April-June 2010, 1(2):73-78
DOI:10.4103/0976-237X.68592  PMID:22114387
The aim of the randomized controlled single blind study is to evaluate the treatment of Miller's class II gingival recessions by coronally positioned flap (CPF) with or without acellular dermal matrix allograft (ADMA). Ten patients with 20 sites with maxillary bilateral Miller's class II facial recession defects were selected randomly into two groups of test (ADMA+CPF) and control (CPF alone) group with each group having 10 recession defects to be treated. The clinical parameters included plaque index (PI), gingival index (GI), probing pocket depth (PPD), clinical attachment level (CAL), recession height (RH), recession width (RW), height of the keratinized tissue (HKT), and thickness of the keratinized tissue (TKT). These measurements were recorded at baseline and after 6 months post-surgery. Statistical analysis was made by the paired "t" test for intragroup and intergroup comparison was done by the unpaired "t" test. The percentage of root coverage for both the experimental and control groups were 82.2% and 50%, respectively. The changes from baseline to 6 months were significant in both the groups for PD, CAL, and RH; however, for parameters such as RW, HKT, and TKT significance was seen only in the experimental group. On comparison between two groups, only TKT showed statistically significance. It can be concluded that the amount of root coverage obtained with ADMA + CPF was superior compared to CPF alone.

Sanjeev Kumar Salaria, Veenu Madaan, Deepak Bala
April-June 2010, 1(2):115-118
DOI:10.4103/0976-237X.68594  PMID:22114396
Periodontitis is a relatively common disease. Various therapies have been recommended for its treatment which includes nonsurgical, antimicrobial, and surgical therapy. In recent years lasers have been used for all the three above-mentioned purposes. Lasers have been applied for hard and soft tissue debridement, contouring as well as the bacterial load reduction in the pocket. Here we present a case report of chronic periodontitis treated with the help of a new technique, laser-assisted modified Widman flap (LAMWF). The surgical procedure followed with a 980 nm diode laser has been described. The present case report resulted in significant pocket depth reduction, attachment gain, and radiographic evidence of bone fill. The laser-assisted modified Widman flap provided excellent results without complications and high patient as well as clinician satisfaction.

Rupali Chadha, Sonali Taneja, Mohit Kumar, Mohit Sharma
April-June 2010, 1(2):70-72
DOI:10.4103/0976-237X.68590  PMID:22114386
The aim of this study was to evaluate the in vitro effect of various obturating materials on fracture resistance of root canal treated teeth. Sixty freshly extracted human mandibular premolars were used. After standardizing the length to 13 mm, the teeth were biomechanically prepared and divided into four groups based on type of obturating materials used. Teeth were embedded in acrylic resin and fracture strength was measured using a universal testing machine. Data obtained was evaluated statistically using one-way ANOVA and the unpaired t-test. Teeth obturated with AH Plus and gutta percha showed higher fracture resistance than those obturated with Resilon-Epiphany. The results suggested that the group obturated with gutta percha and zinc oxide-eugenol sealer had the lowest fracture resistance. No statistically significant difference was found between the unobturated (control) group and the zinc oxide-eugenol group.

NM Roshan, Anand L Shigli, Shobha D Deshpande
April-June 2010, 1(2):94-97
DOI:10.4103/0976-237X.68602  PMID:22114391
Background and Objective: The objective of the study was to monitor Streptococcus mutans (SM) counts in saliva of children aged 5-7 years old over a period of 6 months with the subsequent use of Fuji IX, glass ionomer cement in atraumatic restorative technique (ART). Materials and Methods: One hundred children were selected to receive ART using Fuji IX glass ionomer cement. Caries status was recorded using DMFT index (WHO 1997) and revaluated after 6 months using DMFS index (WHO 1979). Saliva was collected for microbiological assessment of SM count on four occasions, baseline, 1 week, 1 month, and 6 months after ART approach. The results of the microbiological tests were statistically analyzed using the non-parametric Mann-Whitney rank test. Results: The results showed a significant reduction of SM levels in saliva immediately 1 week following the ART approach with mean SM counts of 1.5763 (10 6 CFU/ml) and 1.1286 (10 5 CFU/ml) pre- and 1 week post-ART, respectively. Reduction in the SM count was seen in 89.47% of children after 1 week of ART treatment. The mean SM count after 1 month and 6 months post-ART was 1.4814 (10 6 CFU/ml) and 1.4722(10 6 CFU/ml), respectively. Conclusion: It was concluded from the results that the ART technique was successful in reducing the SM counts in saliva significantly for a period of 1 week post treatment. Although the mean SM counts remained less than the baseline after 6 month evaluation, a trend toward re-establishment of SM to the baseline count was noticed.

Evaluation of surface preparation and maintenance of canal curvature following instrumentation with hand 'K' file and three different Ni-Ti rotary systems: A radiographic and SEM study
Namrata Bhatti, Renu Sroa, Vimal K Sikri
April-June 2010, 1(2):88-93
DOI:10.4103/0976-237X.68599  PMID:22114390
Aim: To determine the shaping ability and cleaning efficiency of hand K-flexofiles, ProTaper, LightSpeed and Mtwo instruments during the preparation of curved root canals in extracted human teeth. Materials and Methods: A total of 120 root canals of mandibular and maxillary molars with curvature more than 20° were divided into four groups of 30 each. In group A, canals were prepared using hand K-flexofiles following the crown down technique. In group B LightSpeed, in group C ProTaper, and in group D Mtwo rotary instruments were used to prepare the root canals. Using pre- and post-instrumentation radiographs, straightening of the canal curvature was determined with Corel Draw 9.0 software tools. The amount of debris and smear layer were quantified at three different areas (coronal, middle, and apical thirds) of root canal using SEM. The collected data were analyzed statistically using Student's paired 't' test. Results: The mean change in curvature for hand K-files was 7.71°, for ProTaper files 6.03°, for Mtwo 5.43°, and for LightSpeed instruments were found to be 4.57°. The percentage change in the curvature for all the four groups was statistically highly significant (P< 0.01). LightSpeed instruments maintained the original canal curvature significantly (P< 0.01) better than the other instruments. For leftover debris, the minimum percentage was found to be associated with ProTaper (65.48%) followed by Mtwo (66.22%), LightSpeed (71.67%) and the maximum with hand K-files (74.16%). However, the difference in mean leftover debris between ProTaper and Mtwo was not significant. Conclusion: ProTaper and Mtwo resulted in good cleaning, and LightSpeed maintained the original canal curvature better than the ProTaper, Mtwo, or Hand K-files.
