Abstract

Introduction: Root canal therapy is an efficacious therapeutic strategy to retain teeth with irreversible pulpal damage. Root canal treatment ensures that teeth with irreversible pulpal damage retain their functional role in the oral cavity. Hence the aim of the study is to determine the incidence of root canal treatment in anterior teeth and its association with the gender.
Materials and method: The data of patients reporting to Saveetha Dental College and Hospitals was reviewed and patients with endodontically treated teeth were selected for the study. It included parameters like age, gender, and endodontically treated teeth type. Chi square tests were carried out using gender as independent variables and endodontically treated teeth number as dependent variable. The statistical analysis was done by Pearson chi square test. P value < 0.05 was considered statistically significant.
Results: Majority (59.8%) of patients was between the age group of 26-50 years, and females (51%) had a slight predominance over males (49%). The most common posterior teeth to undergo root canal treatment were mandibular molars which accounted for approximately 42% of the RCTs among both genders. The Chi square test value was found to be statistically significant (0.001) Conclusion: Majority of the patients undergoing posterior root canal treatment were females, and mandibular molars were the most common posterior teeth to undergo root canal treatment among both the genders.

Introduction

Dental caries is the most common infectious disease of childhood and adolescence and is rated the highest among dental problems [1]. Caries prevalence has increased in the last four decades [2]. If the cariogenic environment persists in the oral cavity, the newly erupted permanent teeth may get decayed [3]. Young permanent teeth have wide dentinal tubules, a large pulp chamber, and high pulp horns, shortening the distance for decay to reach the pulp [4]. If not treated early, infection of the dental pulp will eventually occur [5].

Treatment of pulpal infection in permanent teeth in children and young adults presents a unique challenge to dental clinicians [6]. Tooth preservation is the ultimate goal of modern dental care and root canal therapy (RCT) is an available, efficacious therapeutic strategy to retain teeth. Root canal treatment also known as endodontic treatment is one of the most technically demanding procedures and a very specialized aspect in restorative dentistry requiring a high level of technical skills [7]. It involves a series of steps to aid in clinical decision making. A reliable preoperative diagnosis with radiographic assessment is essential [8]. This will enable correct determination of the desired working length during canal preparation, master gutta percha and obturation. Thus many aspects of RCT such as instruments, medicaments and materials have been developed and modified. Many studies regarding cleaning and shaping techniques quoted that commonly applied techniques were step-back, crown-down and double-flare technique [9-11]. These techniques were chosen as they removed the bulk of micro-organisms which harbour at the apical area [12].

Endodontic treatment will ensure that a diseased tooth or root retains its functional role in the oral cavity [13]. The reasons for prescribing endodontic treatments are mainly related to complications of dental caries. Studies have shown that toothache and dental abscess were the commonest complaints given by patients demanding for RCT [14,15].

Since the prominent factors necessitating RCT are caries related, it is therefore not surprising to observe that the pattern of provision of RCT with respect to the teeth involved tends to follow the reported order of susceptibility of teeth to caries : mandibular second molars being the most susceptible teeth; followed by maxillary first and second molars and mandibular first molars; maxillary and mandibular second premolars; maxillary and mandibular first premolars; maxillary central and lateral incisors; and maxillary and mandibular canines, with mandibular central and lateral incisors being the least susceptible teeth [16,17].

There are limited epidemiological studies relating to the pattern of demand of RCT in India particularly in the southern part of the country. Information on reasons and patterns of demand for treatment is necessary for understanding disease patterns as well as for devising optimal preventive and management strategies. Our team has extensive knowledge and research experience that has translate into high quality publications [18-37].

Hence the aim of this study is to determine the incidence of root canal treatment in posterior teeth and their association with gender among patients attending a private dental college and hospital in Chennai.

Materials and Method

Study design and study setting

The present study was conducted in a university setting (Saveetha dental college and hospitals, Chennai, India). Thus the data available is of patients from the same geographic location and have similar ethnicity. The retrospective study was carried out with the help of digital case records of 5087 patients who reported to the hospital. Ethical clearance to conduct this study was obtained from the Scientific Review Board of the hospital.

Sampling

Data of 5087 patients were reviewed and then extracted. All patients with endodontically treated posterior teeth in the given duration of time period were evaluated. Only relevant data was included to minimize sampling bias. Simple random sampling method was carried out. Cross verification of data for error was done by the presence of additional reviewers and by photographic evaluation. Incomplete data collection was excluded from the study.

Data collection

A single calibrated examiner evaluated the digital case records of patients who reported to Saveetha Dental College from June 2019 to june 2021. For the present study, inclusion criteria were data of patients with endodontically treated anterior teeth. Data obtained were age, gender and endodontically treated teeth number. All obtained data were tabulated into Microsoft excel documents.

Statistical analysis

The collected data was tabulated and analysed with Statistical Package for Social Sciences for Windows, version 20.0 (SPSS Inc., Vancouver style) and results were obtained. Categorical variables were expressed in frequency and percentage. Chi square test was used to test association between categorical variables. Chi square tests were carried out using gender as an independent variable and endodontically treated teeth number as a dependent variable. The statistical analysis was done by pearson chi square test. P value < 0.05 was considered statistically significant.

Results

In our study, the majority (59.8%) of the patients undergoing posterior root canal treatment were between 26-50 years of age (Figure 1).

Discussion

Dental caries is the most common infectious disease of childhood and adolescence and is rated the highest among dental problems [1]. If not treated early, infection of the dental pulp will eventually occur [5]. Treatment of pulpal infection in permanent teeth in children and young adults presents a unique challenge to dental clinicians [6].

Tooth preservation is the ultimate goal of modern dental care and root canal therapy (RCT) is an available, efficacious therapeutic strategy to retain teeth. Root canal treatment also known as endodontic treatment is one of the most technically demanding procedures and a very specialized aspect in restorative dentistry requiring a high level of technical skills [7].

About 51% of the patients encountered in this study were females. Similar findings were recorded by Hollanda et al, and Boucher et al and various other studies [38-40]. Females had been reported to be more concerned about their breath and oral health; hence they appeared to be better motivated to demand for oral health care [38,41].

Though Osama et al and Wayman et al reported higher demand for endodontic treatment by male patients [14,42].

Most of the patients that presented were found in the 26-50 years age group. This can be partly attributed to the location of our hospital which is in a university environment with a huge students’ population. Another possible reason is the high prevalence of dental caries often reported among young and middle aged adults [43]. Patients in their 3rd and 4th decades have been observed to present more for dental treatment [44]. Our result therefore, is in agreement with that of Farrel and Burke, [45] who showed that the highest incidence of endodontic treatment was performed among patients between 21-30 years age group.

In our study, mandibular molars (42%) were the most common teeth undergoing root canal treatment followed by maxillary molars (24.3%). This agrees with the findings of Ridell et al, and Wayman et al [42,46]. The most probable reason was that the mandibular first molar is the first tooth to erupt in the oral cavity; hence it was more prone to caries. In addition, the mandibular molars are more susceptible to food stagnation than the maxillary molars. This indicates to the fact that preventive measures for lower molars are extremely necessary.

Root canal treatments were more frequently undertaken in mandibular teeth than maxillary teeth in our study. This pattern is in contrast with that of Scavo et al [47] and Al-Negrish [48] who reported that 55.69% and 77.7% of their RCTs were performed in maxillary teeth respectively. This could be related to the aesthetic reason, as the upper teeth appear more prominent than the lower teeth during a smile, making the patient more interested in preserving the upper teeth.

Limitations of this study are smaller sample size, and geographical limitations. Further studies with larger sample size and a greater geographical aspect can help in better diagnosis and further treatment planning for endodontic treatments.

Conclusion

Majority of the patients undergoing posterior root canal treatment were females, and mandibular molars were the most common posterior teeth to undergo root canal treatment among both the genders.
