The biologic width--periodontal-restorative relationship

Kamin S

Singapore Dent J, 1989 Dec;14(1):13-5.

An important relationship should exist between the periodontist and restorative dentist. Periodontics and restorative dentistry should not be divisible and all forms of restorations, from a simple filling to a complex precision-retained bridge, should be performed with the health and biology of the periodontium in mind. A very crucial concept which should be borne in the mind of every restorative dentist is the concept of biologic width.

The effect of the surface roughness of porcelain on the adhesion of oral Streptococcus mutans

PMID: 20020077

Dental plaque has a harmful influence on periodontal tissue. When a porcelain restoration is fabricated and refinishing of the glazed surface is inevitable, the increase in surface roughness facilitates the adhesion of plaque and its components. The aim of this in vitro study was to evaluate the effect of surface roughness of glazed or polished porcelain on the adhesion of oral Streptococcus mutans.

Fulltext Susceptibility of selected tooth-coloured dental materials to damage by common erosive acids

Wan Bakar W, McIntyre J

Aust Dent J, 2008 Sep;53(3):226-34.

PMID: 18782366 DOI: 10.1111/j.1834-7819.2008.00053.x

Erosive substances such as gastric acids, lemon juice and even the less erosive cola drinks have been extensively investigated for their destructive effects on enamel. However, their effects on the tooth-coloured restoratives has not been widely analysed. The objective of this study was to assess their effects on the more commonly used glass containing restorative materials in vitro.

Porcelain laminate veneers--considerations for a successful approach in the conservative treatment of aesthetic problems

PMID: 9063109

The development of porcelain laminate veneers has added a new dimension to dentistry in the treatment of unsightly anterior teeth. It is a less invasive procedure than the conventional crown restoration in the treatment of aesthetic problems. This paper highlights some of the considerations in the successful use of porcelain veneers.

SEM analyses of repaired glass-ionomer cements

Jamaluddin A, Pearson GJ

Asian J Aesthet Dent, 1993 Jan;1(1):19-23.

PMID: 8149147

This study assessed the nature of the adhesion in repaired glass-ionomer restorative materials. Two chemically different glass-ionomer cements, Ketac Fil and Chemfil II Cap, and three different methods of conditioning the surface for repair were employed. Specimens of each material were prepared and the cut surfaces were then treated with either 35% phosphoric acid, 35% polyacrylic acid or a combination of phosphoric acid followed by polyacrylic acid. Freshly mixed material was injected against these treated surfaces and allowed to set under simulated intraoral conditions. The specimens were tested to failure in flexion after seven days storage. Assessment of the fractured surfaces was then carried out using the scanning electron microscope. The results showed the occurrence of both adhesive and cohesive failure.

Pulp survival and postoperative treatment needs following selective vs. total caries removal in mature permanent teeth with reversible pulpitis: A randomized clinical trial

Taha NA, Ali MM, Abidin IZ, Khader YS

J Dent, 2024 Dec;151:105408.

PMID: 39442480 DOI: 10.1016/j.jdent.2024.105408

OBJECTIVES: To compare pulpal survival and treatment needs following selective and total caries removal in mature permanent teeth.

METHODS: The design was a parallel double blind, randomized clinical trial. Mature teeth with caries radiographically extending ≥ 2/3 of dentine and without spontaneous pulpitis were included. Teeth were allocated to either selective (SCR) or total caries removal (TCR) using block randomization technique. In the SCR group, caries removal to firm dentine was followed by placement of Biodentine and composite restoration. In TCR group caries removal was to hard dentine; with immediate management by vital pulp therapy (VPT) using Biodentine in case of pulp exposure. Preoperative pain levels were recorded. Teeth were followed up after 6 and 12 months. Data were analyzed using Chi square test and regression analysis.

RESULTS: 124 teeth with a diagnosis of reversible pulpitis were treated (63 in SCR, 61 in TCR). 17/ 61 teeth (28%) in the TCR had pulp exposure, managed by VPT and were successful at recall. Pulp survival was significantly higher in TCR compared to SCR at 6 months (100 % vs 93.65%, p =0.04 respectively) and at 12 months (98.4% vs 82.5, P= 0.003 respectively). Multivariate analysis revealed the type of procedure (SCR vs TCR) and the preoperative pain levels (above or below 5/10) as significant prognostic factors. The odds of failure increased significantly for teeth treated with SCR (OR 27.6, 3.6-212.4, p=0.001) and if preoperative pain levels were ≥5/10 (OR 0.2, 0.04-0.8, P=0.024).

CONCLUSION: Selective caries removal for deep carious lesions in mature teeth failed to reveal overt pulp exposures in more than one quarter of cases and led to significantly lower pulp survival over one year, when compared with complete caries removal and immediate VPT.

CLINICAL SIGNIFICANCE: In deep carious lesions of mature permeant teeth with revrsible pulpitis, total caries removal to hard dentine is recommended for a predictable pulp survival.

CLINICAL TRIAL REGISTRATION: This trial was registered at CliniclTrials.gov (NCT05144711).

Fulltext The Use of Hall's Technique Preformed Metal Crown (HTPMC) by Pediatric Dentists in Malaysia

Jesmin F, Kamarudin A, Baharin F, Ahmad WMABW, Mohammed M, Marya A, et al.

Biomed Res Int, 2021;2021:8424206.

PMID: 34977246 DOI: 10.1155/2021/8424206

Introduction: Hall's technique preformed metal crown (HTPMC) has been used widely by pediatric dentists in developed countries as a new approach for managing decayed primary molars without local anesthesia, caries removal, and tooth preparation. Currently, inadequate information is available regarding the implementation of this technique (HTPMC) in Malaysia. This study is aimed at evaluating the implementation of HTPMC by Malaysia's pediatric dentists and identify the co-occurrence frequencies of the HTPMC implementation with the respondents' demographic profile.

Materials and Methods: A cross-sectional questionnaire-based research was conducted among 65 pediatric dentists in Malaysia. Online questionnaires were distributed to the pediatric dentists employed at public hospitals (MOH) and universities in Malaysia.

Result: It was found that over half of the respondents (65.6%) employed HTPMC. The analysis of the co-occurrence network frequency revealed that a high frequency of female pediatric dentists who were within the age group of 31-40 years old had fulfilled their postgraduation overseas and was employed in the university mainly applied HTPMC.

Conclusion: The application of HTPMC among respondent pediatric dentists in Malaysia was high. However, most respondents considered HTPMC a treatment option only to manage carious primary molar rather than a treatment of choice.

Fulltext Proliferative activity of cells from remaining dental pulp in response to treatment with dental materials

Lutfi AN, Kannan TP, Fazliah MN, Jamaruddin MA, Saidi J

PMID: 20415916 DOI: 10.1111/j.1834-7819.2009.01185.x

The biological examination of pulp injury, repair events and response of dental pulp stem cells to dental restorative materials is important to accomplish restorative treatment, especially to commonly used dental materials in paediatric dentistry, such as glass ionomer cement (GIC) and calcium hydroxide (Ca(OH)(2)) lining cement.
