Introduction: Cervical restorations were known as the least durable type of restoration. Therefore, it is important for clinician to identify the contributing factors that may lead to failure of the restorations. Objective: The purpose of this study was to compare the clinical performance in terms of type of restorative materials and the influence of clinical handling technique of non-carious cervical restorations. Materials and Methods: This cross-sectional study was carried out to patients with restorations on non-carious cervical lesions (NCCLs) at Universiti Sains Islam Malaysia dental clinic. The clinical performance of the restorations was evaluated using the ratings of the United States Public Health Service criteria and analyzed using the Pearson Chi-square. Results: A total of 121 restorations from 34 patients were evaluated by one investigator. Between three restorative materials used which are glass ionomer cements (GIC), RC, and resin-modified GIC (RMGIC), criteria of marginal integrity, marginal discoloration, and anatomic form were not significantly different (P = 0.179, P = 0.134, and P = 0.235, respectively; P < 0.05). In terms of retention and secondary caries, GIC showed statistically significant difference (P = 0.021). The restorations that were evaluated as clinically acceptable showed no significant difference between restorations with and without cavity preparation. Conclusion: Different restorative materials used will affect the longevity of the restorations, but different clinical handling technique does not affect the clinical performances of NCCLs restorations. In this study, the clinical performance of GIC was superior to RC and RMGIC in terms of retention and occurrence of secondary caries but similar in marginal integrity, marginal discoloration, and anatomic form

Copy denture technique is a classic technique for construction of a new denture, based on the existing denture using a replica. This technique helps elderly population in terms of adaptation to a new denture. The aim of this study was to determine the knowledge and practice of copy denture technique among dentists and dental technologists in Malaysia. Two sets of a pre-tested questionnaire was distributed to participants who attended copy denture workshop. The participants were instructed to answer the questionnaires before and after the seminar. A total of 97 responses were collected and only 77 (79.4%) have given a valid feedbacks. The results showed that eventhough 54.5% (n=42) participants had more than 5 years of clinical experiences, 42.9% (n=33) claimed to have limited knowledge in this technique prior to the seminar and 55.9% (n=43) presented with positive attitude towards copy denture. Majority of the participants (74.1%) were uncertain and did not have the skills to perform the copy denture technique. However, following workshop, their attitude towards copy denture increased (+15.6%) and the mean score value was statistically significance (p < 0.005). In conclusion, awareness and practice on copy denture technique should be encouraged to ensure patient’s benefits when replacement denture are required.

The aim of dental treatment is to restore function and improve oral health condition. It is an advantage if the treatment conducted can also improve aesthetic. However, current trend of patient’s demand for aesthetic treatment is challenging. This alarming scenario sometimes does not comply with Shariah and Islamic jurisprudence. Crown lengthening is a procedure to facilitate restoration in certain clinical conditions simultaneously improves the aesthetic in anterior region. It involves manipulation of gingiva which requires removal of soft tissue and/or hard tissue. This paper was aimed to discuss the management of missing teeth with crown lengthening surgery from Islamic perspective. In the selected case, a lady requested to replace her denture with a fixed prosthesis that requires surgery. Initially, the surgical procedure was only planned on the right anterior region. However, during the preliminary stage of determining the treatment outcome; crown lengthening on both sides is advice to harmonize the gingival line. The final decision was to carry out surgical procedure on the site of complaint and crown lengthening surgery on both sides. As expected, the outcome of the treatment significantly improved the aesthetic of the patient. This study employs mainly the comparative case study approach where the detail description of the selected case is mapped to the Shariah principles and guidelines related to aesthetic treatment. The selected Shariah principles and guidelines are based on the commonly accepted school of law. In conclusion, this study found that the treatment proposed by the specialist that is based on function first, followed by correction of aesthetics is in line with the guidelines and principles of Shariah as well as legal maxim that falls under acts are judged by their goals and purpose (al-’Umur-bimaqasidiha). Therefore, basic knowledge on Islamic principle is favourable for dentist and patient in deciding the final treatment plan.

Introduction: Copy denture procedure was introduced in 1962 for the construction of spare denture. However, throughout the years, the procedure has undergone developments in terms of the techniques and materials used for the construction of the replica denture. One of the most popular methods to construct the replica is by using soap box. A group of researchers from USIM have invented Denture Box and the product has been registered with Malaysian Industrial design (MY-16-00546-0101). Therefore, a study was conducted to assess the satisfaction of the Denture Box among dentists and dental technologists. Materials and Methods: Participants who attended the Copy Denture Workshop organized by USIM on 13th April 2017 were asked to make a replica denture from soap-box and Denture Box. A pre-tested questionnaire use 5-point Likert scale was distributed to get their feedback regarding Denture Box after the workshop. Results: Based on their experience during the workshop, all participants (n=41) were satisfied and agreed that the box was 100% practical to use with mean score 4.40±0.49. 92.7% of the participants agreed that the invention can reduce the total cost of denture construction (mean score 4.24±0.57) and 85.5% agreed that Denture Box can save time for denture construction (mean score 4.24±0.71). Interestingly, 87.8% of the participants were excited to use the product in future (mean 4.31±0.67). Conclusion(s): Overall satisfaction from using Denture Box was good. Therefore, Denture Box is ready to be commercialised after some design improvement by taking into consideration a few suggestions made by the participants.

The restorative materials should have the ability to with stand challenging environment such as an acidic environment as the restorative material may be subjected to erosive attack from the low pH of acidic beverages in the oral cavity. The aim of this study was to investigate the effect of Malaysian fruit juices on the surface roughness. Forty disc shape samples were prepared for each of selected tooth coloured restoration (composite, GIC, RMGIC). The surface roughness before immersion was taken then the samples were immersed in the following storage media: distilled water, pineapple juice, mango juice, and tamarind juice. After time intervals of 1 day, the surface roughness was determined for each individual sample using profilometer. Differences were analysed using SPSS version 21. The results showed all materials were found to have increase in the surface roughness after immersion in the juices. The tamarind juices were shown to pose a greater erosive threat to tooth coloured materials than pineapple and mango. Composite showed to have the highest mean changes is surface roughness compared to GIC and RMGIC. In conclusion, the acidic juices affected the surface roughness of the selected tooth coloured restoration.

Introduction: There is an uprising calls on restoring posterior teeth with composite resin due to increasing demands on natural tooth colour restoration and increased concerns about the safety of amalgam restorations. Previous studies had indicated that the teaching of the posterior composites in dental schools were still developing although at the slower pace compared to the recent development of the contemporary dental materials and techniques. Purpose: To evaluate the current teaching of posterior composite restorations among restorative dental lecturers in Malaysia. Methodology: An online questionnaire which sought information on teaching of the composite resin restoration on posterior teeth was developed and had been distributed to 13 dental schools in Malaysia. Findings: The most popular posterior restoration teaching methods among the respondents were lecture (95.7%), demonstration (87.0 %) and PBL (73.9%) while continuous assessment and practical competency test (82.6%) were the most popular assessment methods. For preclinical training, composite resin (95.7%), amalgam (87%), glass ionomer cement (GIC) (34.8%) and resin modified GIC (13%) were the posterior materials taught in the preclinical year. The standard protocol for posterior composite restoration were incremental filling (87.5%) in deep cavity and using circumferential metal bands with wooden wedge (91.7%), with total etch system (95.8%) Significance: Graduates from Malaysia dental school received preclinical, thereotical and clinical teaching on posterior composites although there were variations on the delivery methods, techniques and assessments.

Introduction: Root canal treatment (RCT) and its coronal restoration should be regularly assessed to ensure a successful treatment outcome. The aim of the current study is to evaluate the relationship between the obturation technical quality and coronal restoration in the clinical and radiographic outcome of RCT provided by Malaysian undergraduate students. Materials and Methods: A total of 143 root-treated teeth from 136 patients were evaluated through clinical examinations and periapical radiographs with a mean follow-up period of 2.4 (standard deviation = 1.59) years. The quality of the coronal restoration was classified according to modified United States Public Health Service criteria and the technical quality of the obturation was assessed based on two variables: length and density. Periapical status was evaluated according to periapical index scores. Results: About 64% of the teeth were classified as healthy with a significant reduction of apical periodontitis from 70.3% preoperatively to 36% at reassessment (P < 0.001). About 92.1% of obturation was of acceptable length, whereas 5% underfilled and 2.9% overfilled. Teeth with acceptable obturation length were five times less likely associated with apical periodontitis than the inadequately filled ones. 90% of canals had adequate obturation density with no significant association to apical periodontitis. Teeth restored with intracoronal restorations had 50% more chance of developing apical periodontitis. Inadequately restored teeth and teeth with poor obturation quality were associated with three times more likely apical periodontitis occurrence. The quality of endodontic treatment and the coronal restoration significantly influenced the periapical status (P < 0.001). Conclusion: The radiographic obturation quality and coronal restorations of the RCTs performed by the undergraduate students in a Malaysian public dental school were acceptable in 63.8% of cases with a 64% favorable outcome.

Introduction: Copy denture technique is a classic technique for construction of a new denture based on the favourable aspects of the original denture using a replica. This technique helps in adaptation of new denture in elderly population. The aim of this paper was to assess the knowledge and practice of copy denture technique among dentists and dental technologists. Materials and Methods: A pre-tested questionnaire was sent to all participants who attended the Copy Denture Workshop organized by USIM on 13th April 2017. Two sets of the same questionnaire were distributed to the participant before and after the seminar. Results: Out of 100 participants, only 77% (n=77) have given valid feedbacks. The results showed, even though 54.5% (n=42) participants had more than 5 years of clinical experience, 42.9% (n=33) of the participants have poor knowledge in this technique before the seminar begin. However 55.9% presented with positive attitude towards copy denture. Most of the participants did not know about copy denture technique (43.1%) and the advantages of the technique (32.9%). 74.1% (n=57) participants were uncertain to perform the technique and did not have the skills to perform the copy denture technique. However, after attending the workshop, their attitude towards copy denture increased (+15.6%) and the mean score value was statistically significance with p-value 0.049. Conclusion(s): Awareness and workshop on copy denture technique should be encouraged to improve knowledge and practice, so that the patient who requested for replacement denture will benefit from this technique.

Patient-centred care dentistry offers positive treatment outcome by unique combination of dental practitioners and their patients to improve quality of care and overall health outcomes. As Muslim dental practitioners, they must adhere with the Islamic principles and values in treating their patients with the Maqasid Shari’ah that blended in patient centred care approach. The concept of Maqasid Shari’ah is the purpose and objective of Shari’ah that formulated in the protection of religion, soul, mind, heredity and property. Apart from that, Qawaid Fiqhiyah is the methods that used in solving dental fiqh issues nowadays and that legal maxims is endorsed by the Muslim scholars or authorities. Finally, the dental treatment goal is to increase patients’ quality of life as a servant of Allah and khalifah in the Earth.
