Hardness is an important mechanical property, which has to be ascertained for the dental materials to ensure longevity of restorations placed in the mouth. Technically it is evaluated by making surface indentations and calculating the resistance offered by the material. Many time-tested tests are available to assess hardness. Such engineering tests are modified to the oral situations. An overview of hardness testing is given in this article.
Defective Dental Restorations: A Case Series
Saudi Journal of Oral and Dental Research, 2021
Dental restoration is nowadays becoming key dental treatments, especially use of the composites and replacement of missing teeth using dental fixed partial denture. These can provide temporary relief to the patient, but it had long term side-effects. This article presents case reports of defective composite restoration interdentally, defective cantilever bridge, defective amalgam restoration.
The longevity of different restorations in primary teeth
International Journal of Paediatric Dentistry, 2010
Background and aim. This paper reviews three published papers and adds results from a fourth study which aimed to determine which restorative material would be the best alternative(s) to amalgam (AM) in primary teeth. Design. All studies had a practice-based design and were part of the routine treatment of children and adolescents. The clinicians were assigned which materials to use in a randomised matter in the first three studies which lasted for 7-8 years.
Fabrication of new restorations with a consideration of oral hygiene
Journal of Indian Prosthodontic Society
Maintenance of adequate and effective oral hygiene is crucial for the long-term success of any dental therapy. This article discusses a case that failed due to the poor oral hygiene of the patient. Fabrication of uncomplicated restorations, patient education, motivation, maintenance and recall are important factors to be considered when treatment planning patients with poor oral hygiene.
Assessing teeth and restorations for caries, cracks and leakage
Background: To determine whether clinical examinations and periapical radiographs provide sufficient information to assess the cause of pulp and periapical diseases, the status of teeth when restored and their further treatment needs. Other aims were to determine whether restorations should be removed prior to commencing endodontic treatment, and whether the type and longevity of restorations were related to the presence of disease. Methods: Information was collected regarding 245 restored teeth from 220 consecutive patients referred for endodontic treatment. Teeth were examined before and after the restorations were removed and the findings were compared. Results: Pre-operative examination revealed 47 (19.2 per cent) teeth had caries, 57 (23.3 per cent) had cracks and 96 (39.2 per cent) had marginal breakdown. After restoration removal, the figures were 211 (86.1 per cent), 147 (60 per cent), and 244 (99.6 per cent) respectively. Almost all teeth (93 per cent) had more than one of these factors and periapical radiographs were unreliable indicators of their presence. There was only a 56.1 per cent chance (with 95 per cent Confidence Interval) of finding caries, cracks or marginal breakdown prior to restoration removal. Composite resins were more often associated with early onset and rapid progression of pulp diseases. Conclusions: All restorations should be removed prior to endodontic treatment in order to remove the common factors that may have caused the pulp and periapical disease, and to assess the tooth's prognosis and future treatment needs.
PB Radiographic assessment of the quality of dental restorations
InTRODUCTIOn: The quality of dental restorations can be directly related to the maintenance of periodontal health. Particularly in relation to the contour of interproximal restorations, radiographs allow the assessment of possible excess or lack of proximal contact of restorative materials. OBJECTIvE: To evaluate the frequency of adequate and inadequate restorations, the type of restorative material and the relationship of these parameters with periodontal alterations. METhODS: One hundred digital panoramic radiographs were evaluated, with interproximal restorations being observed on these examinations, classifying them according to the material used and the quality of interproximal restoration and the presence of periodontal alterations. The possible correlation between these parameters was evaluated. RESUlTS: The frequency of adequate restorations was 48% of restored proximal surfaces. Among the inadequate restorations, 46.2% and 53.8% were over-contour and lack of proximal contact, respectively. The restorations were metallic in 64% of cases. COnClUSIOn: Over-contour were more common among metal restorations and lack of proximal contact was more frequent among non-metal restorations. The presence of restorations was associated with increased prevalence of periodontal alterations.
Refurbishment, repair, or replacement of dental restorations - perpetual dilemma
Journal of Dental Health, Oral Disorders & Therapy
Most of the general dentistry work includes replacement of old restorations or repair of some of the restorations to extend their longevity and serviceability. While some consider replacement is the best solution for deteriorated restorations, some other choose repair as a treatment option depending on the cases. Even though repairs may be frequently occurring in daily practice, there are not many randomized control studies to advice about the repair of restorations. Practice based research, should focus on the criteria when a restoration is best repaired or replaced. Both options have their advantages and disadvantages. Proper Diagnosis and treatment planning are the key factors. Assessing the caries risk level, type of restoration to be replaced, restorative materials to be chosen, aesthetic & functional considerations involved are very important for the longevity of the repair work. Teachers of conservative dentistry should continue to develop and refine the teaching of the repai...
