RESUMO
Background/objectives Dental amalgam has been a successful restoration for over a century. However, restoration failures due to secondary caries, fractured teeth or restorations, marginal deficiencies, tooth wear, and secondary caries remain significant concerns. Amalgam-bond, known for its ability to bond amalgam to the tooth structure and prevent percolation, forms a strong bond with vital dentin. This study aimed to compare the outcome of marginal fractures in bonded amalgam and conventional amalgam posterior restorations among patients at a tertiary care dental hospital. Materials and methods Sixty consecutive patients aged 25-35 years, meeting the inclusion and exclusion criteria, participated in this study. A thorough history, clinical examination, and standardized periapical radiographs were conducted. Patients were divided randomly into two equal groups, group A and group B. Group A received bonded amalgam restorations, while group B received conventional amalgam restorations. Polishing was performed at a recall visit after seven days, and a follow-up evaluation was done after two months. The final assessment of marginal fractures was recorded after six months. Results After six months, 28 (46.7%) patients showed no marginal fractures, including 11 males and 17 females. On the other hand, 32 (53.3%) patients exhibited marginal fractures, comprising 17 males and 15 females. The clinical success rate of group A was better than group B (p = 0.001). Conclusion Bonded amalgam demonstrates a high success rate and should be a routine choice for treating carious permanent molars in dental practice.
RESUMO
Objective This cross-sectional study aimed to determine the frequency and types of periapical radiographic lesions (PARLs) associated with pulpitis in patients visiting a tertiary care hospital. Methodology A sample of patients diagnosed with pulpitis, aged 18 years or older, was recruited following a convenient sampling technique. Clinical examinations were conducted to confirm the diagnosis, and radiographic evaluations, including periapical (PA), occlusal, orthopantomogram (OPG), and cone beam computed tomography (CBCT) radiographs were obtained. The radiographs were evaluated for the presence of PA lesions, and the type, size, and location of the lesions were documented. Data were analyzed using IBM SPSS Statistics for Windows, Version 25.0 (IBM Corp., Armonk, NY, USA). Results A total of 120 patients (equal gender ratio) with a mean age of 32.6 ± 6.39 years participated in the study. PA views were the most frequently performed radiographic view (86.7%), followed by occlusal views (8.3%). The most prevalent radiographic lesion was the widening of the periodontal ligament (PDL) space (34.2%), followed by PA granuloma (17.5%) and PA cyst (10.8%). The most frequently encountered diagnosis was pulpitis (51.7%), followed by irreversible pulpitis with apical periodontitis (25.8%). Education level, swelling, pus discharge, medicine history, and tooth wear showed statistically significant associations (P ≤ 0.05) with the variables under investigation. Conclusions The most common lesions observed were widening of the PDL space, PA granuloma, and PA cyst. The findings contribute to the local epidemiological and clinical data, enriching the existing database. Understanding the prevalence and characteristics of PA lesions associated with pulpitis can aid in accurate diagnosis and treatment planning for patients with pulpal pathologies.
