Abstract

Background

This is a cross-sectional retrospective study on survival of amalgam restoration in a Teaching Hospital in Nigeria. There has been no study on this particular subject in Nigeria despite the fact that there is an alarming increase in dental caries and the preferred choice of treatment for over 5 decades has been amalgam restoration.

Materials and methods

It is a retrospective study of dental records of the dental center over a period of 12 years setting certain criteria that must be met by such records. Those that fulfilled these criteria were then recalled for examination.

Results

Two hundred and ninety-four amalgam restorations were placed with primary placements forming 75.69 of all restorations carried out while replacements were 24.31%. Fractured restoration was the commonest cause of failure of restoration accounting for 66% of all replacement. Ditching formed 15.5%, recurrent caries 11.6%, dislodged restoration 5.3%. While cervical overhanging amalgam was 1.6%. 25%, 50%, 75% cumulative failure rate occurs at 4.2 and 6.9 and 9.2 years respectively. While at the same time 73.2 and 19.2% of the restorations lasted for 5 and 10 years respectively.

Conclusion

Primary placement is the preoccupation of the dentist's in Nigeria while replacement rate is low. However, while recurrent caries is the major cause of restoration failure in economies country in Europe and America, it is not the case in this study.

Factors Influencing the Presence of Interproximal Dental Papillae between Maxillary Anterior Teeth: A Clinical and Radiographic Study of the Indian Population

[Year:2013] [Month:July-September] [Volume:4] [Number:3] [Pages:6] [Pages No:158 - 163]

Abstract

Introduction

The presence of a normal and harmonically shaped papilla is crucial to avoid the presence of the ‘black triangle’ which is of major esthetic concern. The distance from the alveolar bone crest (BC) to the base of the contact area (CP) is a significant factor in determining whether a papilla will fill the interdental space.

Aim

To correlate the BC-CP distance with a different anatomic variable using a noninvasive method and to describe a simple, repeatable, observational measuring protocol to contribute to the prosthetic and surgical treatment planning.

Materials and methods

A total of 63 patients were enrolled in the study. A digital radiographs of the interdental embrasure between teeth 12 and 11, 11 and 21 and teeth 21 and 22 were taken with a paralleling cone technique using a RINN film holder. The radiographic data was used to measure the distance between the contact point and the bone crest (BC-CP) and the interdental distance (IDD) at the level of the bone crest.

Results

The number of papillae that filled the interproximal space decreased with the increasing BC-CP and IDD distance.

Conclusion

The vertical and horizontal dimensions of the interdental space influence the existence of interdental papilla.

Evaluation of the Influence of the Nd:YAG Laser and Different Irrigants on the Bond Strength of the Adhesion of the Fiber Posts to Root Dentin using a Self-etching Adhesive System

[Year:2013] [Month:July-September] [Volume:4] [Number:3] [Pages:5] [Pages No:170 - 174]

Abstract

Aim

The aim of this study was to investigate the effects of pretreatment of different irrigating solutions with and without the application the Nd: YAG laser on the bond strength (RU) of the adhesion of the fiberglass post relined with resin composite to the root dentin.

Materials and methods

Sixty-six single bovine incisor roots were divided into 6 groups according to irrigating solution and with/without the apllication of the Nd: YAG laser after root canal filling: S- saline; C-2% chlorhexidine solution, H-2.5% sodium hypochlorite; SL-saline + laser, CL-2% chlorhexidine + laser; HL-2.5% sodium hypochlorite + laser (all n = 11). The roots were standardized up to a file # 80 and root-filled with gutta-percha (Dentsply) and Sealer 26 (Dentsply) by lateral condensation. The root canal filling was partly removed. Afterward, root canals were irrigated with 5 ml of the selected irrigant and the fiberglass post were cemented with epoxy resin curing dual Bifix QM (VOCO) and a self-etch adhesive system Futurabond DC (VOCO). All roots were sectioned transversely, and the push-out tested was performed. The bond strength means were analyzed by the analysis of variance and Tukey test (α= 5%).

Results

The following bond strength MPa values—were recorded for each group: group C—7.77(±1.8)a, LC—6.46 (±2.2)a, S7.33 (±2.2)a, LS 7.35 (±1.68)a, H 5.43 (±1,3)b, LH 5.13 (±1,6)b. A signifcant bond strenght decrease was noticed with the use of 2.5% NaOCl (p < 0.05). No statistical significant difference were found with our without the apllication of the Nd:YAG laser (p > 0.05).

Conclusion

Regardless the irrigant tested, the use of Nd: YAG laser can be indicated prior to cementation of fiberglass without loss in bond strength.

[Year:2013] [Month:July-September] [Volume:4] [Number:3] [Pages:5] [Pages No:175 - 179]

Abstract

Aim

To evaluate the effectiveness of ProTaper universal retreatment system in the removal of root canal filling material with thermomechanical compaction, in comparison to manualmechanical technique, associated with orange oil or eucalyptol.

Materials and methods

Forty extracted lower incisors were filled with thermomechanical compaction technique. After 3 years, the root canal filling was removed by: G1 - manualmechanical technique with orange oil; G2 - manual-mechanical technique with eucalyptol; G3 - ProTaper universal retreatment system with orange oil and G4 - ProTaper universal retreatment system with eucalyptol. In sequence, all root canals were instrumented to F5 instrument. The teeth were longitudinally grooved, images of buccal half were obtained in stereomicroscope and covered area by root canal filling material was measured using image tool software, in cervical, middle and apical radicular thirds. The results were subjected ANOVA and Tukey test (p = 0.05).

Results

In all thirds, the manual-mechanical technique showed lower presence of root canal filling material on root canal dentin in comparison to ProTaper retreatment universal system, regardless of organic solvent used (p < 0.05). There is no difference between organic solvents in removal root canal filling material (p > 0.05).

Conclusion

The ProTaper universal retreatment system showed lower effectiveness in removal root canal filling material than manual-mechanical technique, regardless of organic solvents (orange oil or eucalyptol oil) used.

Clinical significance

Recently rotary instruments have been proposed to removal of root canal filling material. However, there are no studies evaluating its effectiveness in removal root canal filling material in association with orange oil or eucalyptol oil.

Solitary Bone Cysts of the Mandible: Two Case Reports and a Review of Literature

[Year:2013] [Month:July-September] [Volume:4] [Number:3] [Pages:5] [Pages No:193 - 197]

   DOI: 10.5005/jp-journals-10015-1230  |  Open Access |  How to cite  | 

Abstract

Background

The solitary bone cyst is an uncommon nonepithelial cyst. Clinically, the lesion is asymptomatic in the majority of cases and is often accidentally discovered on routine radiological examination, frequently during the second decade of life. Its pathogenesis is still not clearly understood. The majority of solitary bone cysts are located in the mandibular body. This article presents two case reports, one in whom a cyst was diagnosed on routine radiographic examination and other patient reported with dull ache and radiographic examination showed bilateral presentation of the cystic lesion.

Materials and methods

In both patients the biopsy was planned. On surgical opening the lesions presented empty cavities. Curettage was done and overlying bone sent for histopathological examination. Both patients were followed for 1 year.

Results

At follow-up visit both patients were examined clinically and radiographically. In both the patients resolution of the lesion was seen at follow-up visit.

Conclusion

Solitary bone cyst is a rare entity with typical clinical and radiographic features. However, confirmation of diagnosis can be made only by histological examination. Solitary bone cyst may be secondary to an underlying bone pathology. Solitary bone cyst of the head and neck may vary in presentation and severity. Surgical removal is the treatment of choice and provides a satisfying outcome.
