Periapical Status and Quality of Root Canal Fillings in a Moroccan Subpopulation

Abstract

Aim The aim of the study was to assess the prevalence of apical periodontitis (AP) and quality of root canal fillings in an adult Moroccan subpopulation. Methods In the study 508 patients were included, attending the Conservative Dentistry Clinic at the Faculty of Dentistry of Casablanca. 508 panoramic and 709 periapical radiographs were observed. The periapical status of all teeth (with the exception of third molars) was examined according to Ørstavik's periapical index. The statistical analysis was performed with the software Epi Info Version 6.04dfr, April 2001. Results A total of 12719 teeth were examined. 45.3% of patients had apical periodontitis. 4.2% of teeth were treated endodontically and 70.4% of these treatments were inadequate. 91,5% with inadequate endodontic treatment presented apical periodontitis, while only 8,2% with adequate endodontic treatment had apical periodontitis. The lower molars and the upper premolars were the most affected teeth. The presence of apical periodontitis was correlated significantly with insufficient root canal fillings (p < 0.05). Conclusions The present study found a high prevalence of apical periodontitis in this Moroccan population. Inadequate root canal fillings were associated with an increased prevalence of apical periodontitis.

Prevalence of lateral radiolucency, apical root resorption and periapical lesions in Portuguese patients: a CBCT cross-sectional study with a worldwide overview

“…However, this percentage is lower compared with the results from Mukhaimer et al ( 21 ) in Palestine (15.1%) and Oginni et al ( 45 ) in Nigeria (14.4.%), but higher than the proportions documented by Skudutyte-Rysstad & Eriksen ( 20 ) in Norway (1.1%) and Ureyen Kaya et al ( 36 ) in Turkey (1.2%). Additionally, the results of the present study showed that the prevalence of periapical lesions in root canal filled teeth was 54.0%, which is a lower percentage when compared to the one from Morocco (66.8%) ( 46 ) and Spain (64.5%) ( 8 ) but considerably higher than the reported prevalence in Finland (15.3%) ( 22 ). Table 6 and Figure 3 summarize the previous literature regarding the prevalence of periapical lesions ( 7 , 9 , 10 , 15 , 16 , 20 - 25 , 36 - 88 ).…”

Apical Periodontitis in Endodontically Treated Teeth: Cross-sectional Study of New Investigated Risk Factors

“…The current study aimed to investigate risk factors associated to apical periodontitis and to highlight the combined risk of AP assigned to proximal restorations and gingival status in endodontically treated teeth not investigated previously. Epidemiological studies in different populations often reveal a high rate of AP associated with root lled teeth [23][24][25]. The results of the present study indicate that (72.1%) of the root lled teeth had AP, this gure is in the range of those found in previous studies [26][27][28][29], and higher than other reports [30].…”

Prevalence and risk factors of Apical periodontitis in endodontically treated teeth: cross-sectional study in an Adult Moroccan subpopulation

“…El Merini et al recorded in their study AP in 91. 5% of endodontically treated teeth with inadequate root canal treatment, and AP in their study was significantly associated with insufficient root canal fillings (P < 0.05) [ 5 ]. Moreover, in a Meta-analysis of previous cross-sectional studies published between 2012 and 2020, Jakovljevich et al, had shown a significant higher prevalence of AP in treated teeth with inadequate root canal treatment (OR = 4.65; 95% CI 2.75–7.84; p < 0.00001), and a significant higher prevalence of AP in ETT with poor coronal restoration (OR = 1.54; 95% CI 1.16–2.05, p = 0.003) [ 9 ], these findings are all in accordance with the results of the present study.…”

“…Apical periodontitis (AP) is an inflammatory disease of periapical tissues and develops as a host’s immune response to the presence of microorganisms and their irritants within the root canal system [ 1 ]. In most of the cases, AP is a direct consequence of dental caries [ 2 ], nevertheless several authors have reported that AP is more prevalent in endodontically treated teeth (ETT) [ 3 – 5 ].…”

“…Only a few Data on AP prevalence and risk factors for the disease development were published in Africa, most of the previous studies, were carried out in European, American and Asian countries [ 5 , 13 , 21 ]. Therefore, more attempts should be provided to identify a complete picture on AP epidemiology and specific treatments needs in African countries, especially because of the socio-economic outcomes of this Oral health disease and its undeniable impact on general health in the general population [ 22 , 23 ].…”
