Severity and Treatment Difficulty of Impacted Maxillary Canine among Orthodontic Patients in Riyadh, Saudi Arabia

Prevalence of impacted and transmigrated canines in orthodontic patients - A radiographic study

Background

The canine plays a vital role in dentofacial aesthetics and function. It supports the base of the alar and upper lip, which are crucial for smile aesthetics. When impacted, these functions are lost, leading to low self-esteem and overall poor health-related quality of life. The present study was conducted to find the prevalence of impacted and transmigrated canines in orthodontic patients and also to find the most prevalent type of canine impaction.

Materials and Methods

This retrospective study was conducted in a hospital setting at Dental College. A total of 3050 OPGs (Orthopantomagram) of patients who visited dental hospitals for orthodontic treatment constituted the final sample. Demographic details regarding age, gender, and place of residence were collected from the patients. Evaluation of sample radiographs on the standard light box was performed to collect data regarding impacted and transmigrated canines. Statistical analysis was performed using descriptive statistics and Chi-square test.

Results

Prevalence of impacted canine was found to be 2.46%. Impacted canine prevalence of 1.53% and 2.85% was reported in males and females, respectively. Only two female patients had transmigrated mandibular impacted canines. Comparison of arch showed a statistically significant (P value 0.02) higher prevalence in the maxillary arch, which was 1.54%, and in the mandibular arch, it was 0.92%. The present study reported significantly more unilateral impactions (P value 0.00) than bilateral impactions.

Conclusion

The overall prevalence for impacted canine was 2.46%. Prevalence was higher in female patients. Early diagnosis of impacted canines is vital for planning orthodontic treatment in such patients.

Prevalence of canine impaction in different cities of Saudi Arabia: A systematic review

Background

To our knowledge, no systematic review assessed and gathered information about the prevalence of impacted canines among the Saudi population. The purpose of this study was to critically assess the previously published studies about the prevalence of canine impaction according to impaction type (buccal/ palatal), gender (male/female), and location (maxillary/mandibular, right/left), are among the Saudi population.

Methods

PubMed (MEDLINE), Scopus, the Web of Science, Dimensions, and Semantic Scholar databases were searched systemically for articles related to the topic of the study published between 1987 and 2022. The PRISMA statements were used to conduct a systematic review with the help of the Best Practice for Survey and the Public Opinion Research scales by the American Association for Public Opinion Research (AAPOR) to assess and evaluate the selected studies' quality.

Results

The initial search of the databases yielded 221 articles. After discarding duplicates, 161 were selected for further evaluation. Eventually, 16 articles were selected for inclusion in this study. Regarding the quality of the selected articles, all articles, except one, were of high quality. Only one was of medium quality.

Conclusion

It was found that the incidence of palatal canine impactions was higher than buccal impactions. Females had a higher prevalence of canine impactions as compared to males. There were more canine impactions in the maxilla than the mandible and more on the left side than the right one.

Prevalence of canine impaction in the western province of Saudi Arabia: A cross-sectional survey

BACKGROUND/AIM

Canine tooth impaction could have a negative influence on the stomatognathic system and could make it difficult for clinicians to manage malocclusions. The aim of this retrospective study was to investigate the prevalence of canine impaction, which could be a cause of malocclusion, in the population in the western province of Saudi Arabia.

METHODS

A retrospective analysis of digital orthopantomograms (OPGs) of 400 patients aged 12-40 years, who are citizens of Saudi Arabia residing in the western province and who presented for treatment at the dental clinics of Batterjee Medical College, Jeddah, Saudi Arabia were included. The OPGs and dental records of these patients were reviewed for canine impaction and were categorized based on age, gender, and type of impaction.

RESULTS

The prevalence of patients that exhibited canine impaction was found to be 4%. Males had a significantly higher percentage of prevalence than females (P < 0.016), and impaction was significantly higher among patients aged below 18 years (P < 0.001). Moreover, the most commonly observed impaction was mandibular canine impaction (87.5%).

CONCLUSIONS

Prevention of malocclusion and maintenance of a normal dentition (better aesthetics and chewing) necessitates early detection of impacted canines.
