Objective: This study investigated the prevalence of malocclusion in the Qassim region of Saudi Arabia. Methods: This retrospective observational study involved casts from 229 patients who visited Qassim University dental clinics between 2018 and 2021. The casts were divided based on gender and malocclusion. The following occlusal patterns were considered in the study: Class I, Class II, and Class III malocclusions. Occlusal traits such as anterior crossbite, posterior crossbite, open bite, deep bite, and increased overjet were also recorded. In addition, dental anomalies such as hyperdontia, hypodontia, diastema, ectopic eruption, transposition, and peg-shaped teeth were investigated. All measurements were recorded using a Yaluo stainless steel electronic digital display caliper vernier. Data were analyzed using the Statistical Package for the Social Sciences for Windows version 23. Results: Majority of the patients were female (164, 71.6%), and 65 (28.4%) were male. Class I was the most prevalent occlusion type, with 183 (79.9%), followed by 37 (16.2%) in Class II, and finally, only 9 (3.9%) in Class III. The dental anomalies in the study group, specifically occlusion types, reveal that Class I has the highest percentage of dental anomalies, with 15.8% more than other types. Conclusion: According to the statistics, the majority of people in Qassim have adequate occlusion, but the prevalence of dental anomalies may make treatment more challenging. As a result, the research on malocclusion frequency is highly valued and crucial for gathering data for a national database and for treatment planning.
