The prevalence of root dilacerations in a Turkish population

Abstract

Objectives: The aim of this study was to determine the prevalence of root dilaceration in a Turkish dental patient population with respect to sexes and dental localization in relation between sex and this anomaly. Study Design: A retrospective study was performed using periapical radiography of 2,124 patients ranging in age from 15 to 65. All data (age, sex and systemic disease or syndrome) was obtained from the files. These patients were analyzed for root dilaceration. Descriptive characteristics of sexes, jaws, and dental localization were recorded. The Pearson chi-squared test was used. Results: Of 2,251 patients, 214 (9.5%) had root dilaceration. Root dilacerations were determined in 276 (4.3%) of 6386 teeth belong to 2251 patients. Anomalies were found in 9.8% of males compared with 9.3% of females. However, this difference was not statistically significant (p>0.05). Root dilacerations were similarly distributed between maxilla and mandible. The most frequently root dilacerated teeth were found to be mandibular third molars (12.8%), followed by maxillary third molars (7.4%), maxillary first molars (6.7%). Root dilaceration was not detected in maxillary central incisors, mandibular central incisors and mandibular lateral incisors. Conclusion: According to our results, root dilaceration is an uncommon developmental anomaly which mostly occurs in the posterior teeth that is not also possible to have trauma. The radiographic diagnosis of this anomaly is important before surgery and orthodontics treatment, but firstly endodontic treatment.

Distal root curvatures in mandibular molars: analysis using digital panoramic X-rays

“…This is because once root development is complete, from 15 years of age no further dental morphological changes occur and hence in this study that analysis has been disregarded. When examining the degree of root curvature in molars of men and women, we did not find any significant differences, which is consistent with other reports that analyse different dental groups [3,10,15,18]. On this last point, it is possible to find some studies that do indeed report significant differences in the prevalence of root dilacerations between men and women [6], although the degree of the curvatures of the teeth has not been explored and they are not classified as dilacerated.…”

“…Miloglu et al [18] report a prevalence of dilacerations (> 90°) of 4.3% (n = 276) in a Turkish sample population (6,386 permanent teeth of all types) using periapical X-rays, whereas Bodrumlu et al [3] report a prevalence of 3.4% (n = 317) in the same population sample (9,406 permanent teeth of all types) using the same method. Also, Udoye and Jafarzadeh [25] report a prevalence of dilaceration of 2.97% (> 90°) in a Nigerian sample population (706 permanent teeth of all types) using periapical X-rays.…”

3rd Molar variations via radiograph

“…These differences in Maxillary third molars can be accounted due to cultural diversity in our radiographs. Miloglo O et al [20] reported in a Turkish population dilaceration in Maxillary and Mandibular third molar to be about 7.4% and 12.8% respectively, which is close to our finding of 11% and 20% in Maxillary and Mandibular third molars respectively.…”

Management of idiopathic alveolar bone necrosis associated with oroantral fistula after upper left first molar extraction

“…9 Dilacerated root also may be easily fractured during tooth extraction. 10,11 Clinically the lesion appear as exposed bone which is painful in 60 to 69 percent of cases. 1 This patient complained of swelling and pain at post extraction site for 2 months before escaping fluid when drinking, showing that oroantral fistula develop after the presence of osteonecrosis.…”
