Aim: The aim of this study was to detect the prevalence of dental malpractice in the fields of oral surgery, endodontics, prosthodontics (crowns and bridges), and restorative dentistry in the Kingdom of Saudi Arabia.

Materials and Methods: 378 patients aged ≥ 18 years were randomly selected and clinically examined for substandard dental treatments done in dental premises (hospitals, polyclinics, private clinics) in the Kingdom of Saudi Arabia. The study was conducted in the period July through September 2018. Each patient was clinically examined in the following fields: Prosthodontics (substandard crown and bridge placement in relation to tooth preparation and crown adaptation, PFM  crown and bridge placement on feather edge finishing line, substandard post and core), endodontics (substandard root canal treatment), restorative dentistry (overhanging restorations: class II, III,  IV, V), and oral surgery (dry socket due to traumatic prolonged tooth extraction and/or a fractured tooth part left in the socket. In addition to clinical examination, radiographs were also used. The results were documented in a patient examination form then statistically analyzed using Chi-Square Test.

Results: There was a significant difference in the percentages of dental malpractice (endodontics, restorative dentistry, prosthodontics, oral surgery) p = 0.000 < 0.05. Therefore, endodontics malpractice was the first 42.5%, restorative dentistry malpractice was the second 28.4%, prosthodontics malpractice was the third 26.4%, and oral surgery malpractice was the fourth 2.7%.

Conclusion: Dentists must consider ethical principles and acceptable standards and protocols of diagnosis and treatment. They also have an ethical responsibility to limit their extent and scope of practice to their level of professional experience in oral surgery. There is high need for improving the technical skills of practitioners in root canal treatments. Also, stressing on using wedges with matrices to avoid overhanging dental restorations is advised. Differences between societies might play a role in the lower percentages of prosthodontics malpractice in KSA.

The miliolite limestone of Kachchh and Saurashtra areas of the Gujarat state, western India is a unique
sedimentary sequence of the Middle to Late Pleistocene age that has been studied mainly for its
relationship with sea level changes and local tectonics. In Kachchh the Katrol Hill Fault (KHF) is
considered as an active fault characterized by earthquake occurrences. The occurrence of fibrous form of
calcite in miliolite limestone of the Gangeswar area in Katrol Hill Range (KHR) has been described in
this study using thin section and SEM-EDS, and considered as manifestation of active tectonics during the
deposition and diagenesis of the miliolite limestone in the study area as its morphogenesis is linked with
elevated radon in moist environment. Thus, the study provides a new tool to assess the earthquake prone
areas.
