Oral Health-Related Quality of Life Following Root Canal Treatment of First Permanent Molars Among Children. A Cross-Sectional Study.

Aim: This study aimed to assess the Oral Health-Related Quality of Life (OHRQoL) of pediatric patients (9-18 years old) who underwent root canal treatment (RCT) on first permanent molars (FPMs). Methods: A cross-sectional study was conducted at three healthcare centers in Jeddah, Saudi Arabia. Participants (n = 482) completed the validated OHIP5-Ar questionnaire to assess OHRQoL. Responses were classified as "optimal" (no problems) or "less than optimal" (any reported problems). Logistic regression analyzed the relationship between OHRQoL and sociodemographic factors. Results: There were 66.8% children reported optimal OHRQoL after RCT. Logistic regression showed no significant association between optimal OHRQoL and gender, family income, or location of treated tooth. However, although not statistically significant. Treating only one FPM with RCT (compared to multiple teeth) and lower family income (compared to higher income) were more likely to have decreased or increased odds of optimal OHRQoL (AOR = 0.684 or 1.424; respectively). Conclusion: RCT on FPMs can be a successful treatment option for pediatric patients, offering optimal oral health-related quality of life.

Outcomes of root canal treatment of first permanent molars among children in Jeddah, Saudi Arabia: A retrospective cohort study.

Objectives: The first permanent molar (FPM) is considered the tooth most susceptible to caries, as it is the first permanent tooth to erupt in the oral cavity, making it susceptible to environmental conditions that may appear as caries, hypoplasia, or hypomineralization. Several treatment options are available for managing deep caries, including root canal treatment (RCT). However, there is a lack of data on the success and failure rates of RCT in FPM among children. This study aimed to determine the success and failure rates of RCT in FPM among children and related factors. Methods: This retrospective cohort study was conducted at three major centers in Jeddah, Saudi Arabia. Children aged 9-18 years who underwent an RCT between 2010 and 2019 were included. Clinical and radiographic examinations were also performed. Results: Based on the loose criteria, most of the evaluated teeth (79.6%) were successfully treated. The treatment failed in only 20.4% of participants. Older patients and teeth with acceptable restoration quality had an increased success rate compared to younger patients and teeth with unacceptable restoration quality. A shorter time lapse between treatment and assessment resulted in a lower success rate compared to a longer time lapse. Based on strict criteria, 72.9% of the patients were successfully treated. The use of a microscope and teeth with acceptable restoration quality resulted in an increased success rate compared to teeth treated without the microscope and with unacceptable restoration quality. Conclusions: The success rate of this procedure was high. Several factors, including older age, acceptable restoration quality, and the use of a microscope, increase the probability of success.
