Aim: The aim of this study was to detect the use of resin composite and amalgam restorations placed in
permanent posterior teeth by undergraduate dental students in university dental hospitals in Saudi Arabia.
Materials and Methods: 276 patients aged ≥8 years were randomly selected and clinically examined for
amalgam and resin composite restorations placed in permanent posterior teeth with living pulps by
undergraduate dental students in university dental hospitals in Saudi Arabia. The restorations were placed
in teeth preparations Class I and Class II. Also, bitewing and or periapical radiographs were used to define
the depth of the cavity. The data obtained were documented in a patient examination form then statistically
analyzed using Chi-Square Test or Fisher-Freeman-Halton Test.
Results: Composite was the main kind of restoration placed by dental students. There was an insignificant
relationship between the kind of restoration (amalgam or composite) and the tooth type
(maxillary/mandibular premolar and maxillary/mandibular molar), the class of tooth preparation, the cavity
depth, the age of the patient, and the gender of the patient p > 0.05.
Conclusion: Composite was the most commonly restorative material used by dental students. Gradual
reduction in the use of amalgam should be evidence-based. Students should obtain the necessary
competencies for decision making according to each individual case.

Introduction: Root canal treatment (RCT) is one of the most common endodontic procedures for which
patient visit the dentist. It is very important to know about the knowledge of RCT.
Methods: Multiple choice questionnaires regarding knowledge of root canal treatment was distributed to
65 patients in the community. Among them 35 males and 30 female were participated. The data were
collected and analysis was performed using SPSS using descriptive statistics.
Results: Among 65 patients, 31 were female and 34 were male. Various knowledge and practice based
questions where male of the respondents 70.6% had the known about RCT and 64.5% of female know about
it. 50.5% of male came to know about it through nearby clinic and secondly from relatives and friends.
22.6% female and 20.6% of male immediately seek for treatment. Most of the male respondents chose RCT
over extraction.
Conclusion: Knowledge and awareness about the RCT can conserve the teeth from extraction.

Third molar extraction is the most routinely done minor surgical procedure. Every clinician undertakes the
third molar for clinical and radiographic assessment before carrying out the treatment but there is
customization and individual variation in each.
The present survey aims to find out the perception of general dentist regarding treatment tailoring for third
molar and also intends to find out the protocol of management of third molar extraction amongst them
