RESUMO

BACKGROUND: An impacted tooth is a tooth which does not reach the occlusal plane even after two-thirds root formation. Conditions associated with impacted teeth include trismus, cystic lesions, and cervical caries of second molars. The objective of this study was to evaluate the occurrence of carious lesions in the distal aspect of the mandibular second molar and its association with the presence of mandibular third molars. METHODS: A cross-sectional study was conducted from September 2018 to September 2020. Approval was taken from the Institutional Review Committee with reference number 90/77/78. Orthopantomograms of patients aged 18 years or older were studied. Information on age, gender, mandibular second and third molars were recorded. Convenient sampling was done. Statistical analysis was done using Statistical Package for Social Sciences version 21. RESULTS: A total of 626 radiographs were studied of which mesioangular impaction (35.3%) was the most prominent type and followed by horizontal impaction, causing distal caries in second molars. The age group between 20-40 years and female gender had the higher prevalence of distal caries in second molar teeth. There was a significant correlation between gender and cavity existence (p=0.00), between impaction and existence of decay (p=0.00), and depth of impaction with cavity formation (p=0.004). CONCLUSIONS: A total of 31.8% of the patients with impacted mandibular third molars had distal cervical caries in second molars. Mesioangular type, female gender, type A were the prominent factors associated with distal caries in second molar teeth due to impacted third molars.

RESUMO

INTRODUCTION: Third molar impaction is a common patient complaint in dentistry. Common symptoms are localized pain, swelling, bleeding, and difficulty in mouth opening. Since dental students deal with patients early in their education, for better skill, they should have knowledge of various teeth impactions. Hence, the objective was to find out the knowledge of impacted teeth among undergraduate dental students of a medical college. METHODS: A descriptive cross-sectional study was conducted among bachelor in dental surgery students of a medical college from November 30, 2020 to April 3, 2021. Data collection was done by convenience sampling after receiving ethical clearance from Institutional Review Committee (Reference 1208202006). A structured questionnaire in Google Forms was sent to 221 participants via Viber. Out of 213 responses received, 144 were analyzed in Excel after discarding for duplication and other errors. Descriptive statistics such as mean, standard deviation, frequency, and percentage were analyzed. RESULTS: Out of the total of 144 participants, only 81 (56.3%) (47.89-91.4 at 95% Confidence Interval) had known about the term 'impacted teeth' before joining Bachelor in Dental Surgery course. The source of information was mostly the internet 27 (18.8%) followed by dentist 23 (16%). Most students 116 (80.6%) were familiar with third molar impactions, 62 (43.1%) knew about types of impacted teeth/impaction, and 100 (69.4%) were aware of the complications of not removing impacted teeth. CONCLUSIONS: Dental students should be provided with appropriate 'impacted teeth' education supported by practical experience. More detailed information regarding impacted teeth should be included in the curriculum for better understanding.

RESUMO

AIM: Odontomas are odontogenic tumours of the jaws; they are generally asymptomatic with an unknown aetiology. This study was conducted on non-syndromic children aged 9 to 14 years to explore the side effects deriving from the presence of these benign tumours, as retention, transmigration, ectopic eruption of permanent teeth and the permanence of primary teeth in the affected area. METHODS: Two hundred panoramic (OPT) and 92 Cone Beam Computed Tomography radiographs (CBCT) of patients (130 males and 70 females) were analysed from February 2018 to December 2019. Two hundred odontomas (145 compound and 55 complex type) and 800 teeth (160 primary and 640 permanent) were included. RESULTS: The prevalence of these tumours in both male and female subjects was 65% and 35%, respectively; the prevalence of compound odontomas in maxillary and mandibular bones was respectively 27.58% and 72.41%. The prevalence of complex odontomas in maxillary bones in female and male subjects was 37.5% and 62.5% respectively. It was observed the presence of a primary tooth in 81% of cases, the presence of retained teeth in 16.5% and a dental transmigration in the remaining 2.5% of cases in the compound type. Gender (p?=0.158) has no significant correlation. CONCLUSIONS: An early diagnosis and removal of odontomas in primary dentition is crucial in order to prevent later dental complications. Since the detection of odontomas is mainly an accidental radiological finding, the need for routine radiographic analysis should be highlighted.

RESUMO

The objective of this study was to study the incidence of type of impaction of mandibular third molars based on the classifications of Pell and Gregory and Winter, which included angulation of the tooth and level of the occlusal surface of the third molar with respect to the second molar, respectively, in a sample of Saudi population in central region. In this retrospective study, orthopantomograms (OPGs) of 17760 patients were examined, who were reported by the Dental University Hospital (DUH) at King Saud University, Riyadh, Saudi Arabia, between the years 2016 and 2020. Out of 17760 radiographs, 2187 (12.31%) patients presented with at least one impacted third molar. Out of which, 1337 (7.52%) patients had bilateral impaction and 850 (4.78%) patients had unilateral impaction (p < 0.001). No gender predominance was noted in the impaction status (p > 0.05). In bilateral impaction, 671 were male (50.2%) and 666 were female (49.8%). Among unilateral impaction, 394 (46.4%) were male and 456 (53.6%) were female. Mesioangular angulation was the most common pattern of impaction (65%) followed by vertical angulation in both bilateral and unilateral impactions. Level A impaction was found to be highest in both bilateral and unilateral impactions which are 48.02% and 54.0%, respectively (p < 0.05). Our study highlights mesioangular impaction and level "A" as the most frequently encountered angulation and level of impaction in impacted teeth. This study result provides us useful data regarding the radiographic status of mandibular third molars in the population of Saudi Arabia.

RESUMO

Background: Third molar impaction, if left untreated, has the potential to cause several complications. The evaluation of surgical difficulty of impacted third molar extraction aids in better formulation of treatment plan by minimizing surgical complications. Objective: This study aimed to determine the prevalence of third molar impaction and related pathologic conditions in a cohort of patients living in North-eastern Peninsular Malaysia. Methods: In this retrospective study, 490 orthopantomograms (OPGs) of patients who were referred to the Oral and Maxillofacial Surgery department between January 2010 and December 2019 were assessed. Data including age, gender, ethnicity, frequency of third molar impactions, their angulations and levels of eruption, retromolar space, and associated pathologic conditions were collected. Statistical analysis was performed using the Statistical Package for Social Sciences (SPSS) version 24.0. The significance level was set to P < 0.05. Results: A total of 490 patients with a mean age of 28.87 years (range: 20-64) demonstrated 1957 impacted third molars (1022 mandibular + 935 maxillary). Impacted third molars were more likely present in females than males (1:2.20) (p < 0.05); and in Malay-ethnic (44.49%) patients followed by Chinese (34.45%) and Indians (21.02%). Mesioangular was the most common angulation of impaction both in the maxilla (24.68%) and mandible (18.34%). The most common pattern of third molar impaction was IIA (61.67%), and the retromolar space was significantly larger in males (13.6 mm; P < 0.05) than females (11.6 mm). The most frequently occurring pathological condition associated with third molars impaction is dental caries in the second or third molar (15.38%). Conclusions: This study highlights mesioangular impaction with their occlusal plane at the same level as the occlusal plane of the adjacent tooth being the most prevalent pattern of third molar impaction in North-eastern Peninsular Malaysia.

RESUMO

Classifications of impacted teeth allow defining the type and degree of retention, as well as assessing the degree of difficulty of the procedure. The aim of this study was to conduct retrospective analysis of the degree of retention and difficulty in the surgical removal of impacted mandibular third molars in the clinical material of the Department of Oral Surgery in 2013-2018. This study included 1585 dental panoramic radiographs of patients of the Department of Oral Surgery, who reported in 2013-2018, in order to perform surgical removal of the impacted mandibular third molar. Based on dental panoramic radiographs, the degree of retention was determined based on classifications according to Winter, according to Pell and Gregory, according to Tetsch and Wagner, and according to Asanami and Kasazaki. The difficulty of the procedure was also assessed based on the Pederson index. The most common types of lower wisdom tooth impaction are as follows: in Winter's classification, mesial-angular impaction; in Tetsch and Wagner's classification, oblique medial-angular impaction; in Pell and Gregory's classification, impaction grade 2A; and in Asanami and Kasazaki's classification, 3A and anterior inclination. In most cases of surgical removal of an impacted tooth, the anticipated difficulty of the procedure was rated as very difficult.

RESUMO

OBJECTIVE: The aim of this study was to evaluate if delayed dental development is a cause of postponed care for patients with impacted maxillary canine (IMC). MATERIALS AND METHODS: This case-control study was based on 403,355 children and adolescents in Region Västra Götaland, Sweden. The subjects, who were in the age range of 9-16 years during the period of 2011-2013, underwent surgical exposure or removal of a maxillary canine. Demirjian's dental age assessment was carried out on panoramic radiographs. RESULTS: In total, 1028 patients, 514 with IMC and 514 age- and gender-matched controls, were enrolled. The patients with IMC exhibited a dental development delay of 0.2 years compared to the control group. In the impaction sub-groups, the female patients, patients in the chronological age group of 12-13 years, and patients with palatally positioned IMC had a significantly lower dental age than their paired-control subjects. CONCLUSIONS: Overall, the difference in dental age between patients with or without IMC is significant but small, and as such is likely of minor clinical relevance. Therefore, the timing of preventive care and treatment for patients with IMC should be the same as that for patients with normally erupting canines.

RESUMO

OBJECTIVES: The aims of the present study were to evaluate the relative incidence of alveolar osteitis (AO) after mandibular third molar surgery, post-operative findings and local expression of bone markers and cytokines. STUDY DESIGN: In 445 patients, unilateral surgical third molars extractions were undertaken (584 teeth). Bone markers and cytokines were explored at the AO side and on the un-operated contralateral side and compared with the levels in samples from a control group of 18 persons without AO. RESULTS: The relative incidence of AO was 4.6%. Patients (n = 27) with AO were invited to participate in the study and 21 (77.8%) did so. Patients with AO had 1-4 extra visits for treatment of AO, the mean follow-up time was 2.6 days for all patients. There were significantly higher levels of bone markers and cytokines in the AO site compared with the un-operated contralateral site, except for Epidermal growth factor (EGF). No significant difference in expression of bone markers and cytokines between the AO and control groups was found. Lower maximum inter-incisor opening (MIO) was correlated with increased Macrophage inflammatory protein 1 alpha. A negative correlation between patients' complaint of trismus and MIO was seen. CONCLUSIONS: The relative incidence of AO was low in our patient group treated with surgical removal of third molars. AO was more frequently seen in female patients. Treatment of AO required up to four extra visits. The study provides some information on the role of cytokines in AO; but further studies are required.

RESUMO

OBJECTIVE: Unerupted permanent teeth are amongst the most commonly occurring dental anomalies in adults and present unique treatment challenges. The aim of this retrospective study was to (1) identify the prevalence of adult patients with unerupted teeth attending a multidisciplinary clinic and (2) to identify predictors (age, gender, incisor and skeletal classification) which influence the patients treatment decision. MATERIAL AND METHODS: Consecutive adult patients with unerupted permanent teeth attending the Joint Orthodontic-Restorative clinic were identified. Study variables were collected using a prespecified data collection form. Descriptive statistics were employed; Fisher's exact test was used to detect associations between variables and treatment decision outcome. Ordinal logistic regression derived multinomial regression relative risk ratios (RRR) and 95% confidence intervals (CI) were calculated for the effect of age, gender, incisor and skeletal classification on treatment decision/outcome. RESULTS: Sixty-six patients with impacted teeth were identified from a sample of 483. The prevalence of adults with unerupted teeth was 13.7%. The mean age was 30.7 years (SD 11.2). The majority of the sample had a Class I incisor relationship (54.6%) or Class I skeletal base relationship (54.6%), and the most common distribution of impacted teeth was a single unerupted upper right canine (34.9%). Orthodontic treatment (non-extraction or extraction basis incorporating the alignment or removal of impacted teeth) and restorative treatment only were equally favoured. Factors including age, gender, incisor and skeletal classification did not appear to influence or predict the final treatment decision. CONCLUSIONS: In this sample, adults presenting with impacted teeth favoured certain treatment modalities: orthodontic treatment only and restorative treatment only. Factors such as age, gender, incisor and skeletal classification did not influence the outcome.

RESUMO

PURPOSE: There is limited evidence available regarding when the best time to extract impacted lower third molars (iLM3). Thus, the current study is aimed to examine the association between the age of patients during the time of extraction of their iLM3 and the sequelae of their adjacent second molar (LM2) in order to find a better time to remove iLM3. METHODS: Retrospective cohort study was conducted with a total of 15,432 patients from ages 16-45 years old who had their first surgical extraction of iLM3. Statistical analysis was performed to evaluate variables in association with the sequalae of LM2. Adjusted odds ratios (AOR) were calculated to show the influence of the age of patients by multivariate regression model. RESULTS: Patients who had iLM3 extraction over 22 years of age had a significantly higher risk of having LM2 pulpal disease (AOR: from 2.84 in 23-25 age to 11.58 in >35 age). Significantly higher risk of having LM2 periodontal conditions was found in individuals over 31 years of age (AOR: 1.47 in 31-35 age, 1.90 in >35 age), with prior periodontitis (AOR: 1.97) or complicated odontectomy (AOR: 1.43). The risk of LM2 being extracted due to an untreatable condition was highest in patients more than 35 years old (AOR: 14.38). CONCLUSION: The age of patients having iLM3 extracted was independently associated with various LM2 sequelae. We suggest that patients can have their iLM3 extracted in their college/university age (19-22-year-old) to minimize complications on the adjacent LM2.

RESUMO

Aim: To evaluate the prevalence of impacted teeth in Saudi patients and compare between male and female subjects. Method: This cross-sectional study comprised of Saudi patients who attended dental clinics in major hospitals in the Eastern Province of Saudi Arabia. Patients' dental records and panoramic radiographs were reviewed retrospectively. Impacted teeth excluding third molars and spaces occupied by primary, permanent, and transmigrated teeth were recorded from panoramic radiographs. The Pearson chi-squared test was performed to determine gender differences regarding impacted teeth and spaces occupied by other teeth. Results: The study included radiographs of 539 patients with a mean age of 23.3 ± 10.8 years. Seventy-one patients (13.2%) had at least one impacted tooth. The total number of impacted teeth was 115 in the sample, out of which 91 (79.1%) were in the upper arch and 24 (20.8%) in the lower arch. Fifty-eight maxillary canines (50.4%) were impacted making them the most commonly impacted teeth, followed by 21 upper second premolars (18.2%) and 14 lower second premolars (12.2%). More females (70.7%) than males (29.3%) had impacted teeth (P=0.82). Of 61 spaces occupied, 35 (57.4%) were occupied by permanent teeth, 24 (39.3%) by primary teeth, and 2 (3.3%) by transmigrated teeth. Greater proportions of spaces were occupied in female than male participants (P > 0.05). Conclusion: There was a high prevalence of impacted teeth in Saudi patients. The canines were the most commonly impacted teeth followed by the second premolars. Females demonstrated a higher occurrence of impacted teeth than males. Early detection of impacted teeth can help prevent malocclusion and maintain a healthy dentition.

RESUMO

OBJECTIVES: To examine the association between third molars and orofacial pain. We hypothesized that impacted third molars are a cause of orofacial pain. METHODS: Magnetic resonance images of 1808 participants from two population-based cohorts from Northeastern Germany were analysed to define the status of third molars according to the Pell and Gregory classification. A self-reported questionnaire and a clinical dental examination were used to detect chronic and acute complaints of orofacial pain, masticatory muscle pain, migraine and other types of headache. Logistic regression models were used to analyse the associations between third molar status and orofacial pain. RESULTS: Individuals with impacted third molars in the maxilla had a higher chance of chronic orofacial pain than those with erupted third molars (odds ratio 2.19; 95% CI 1.19-4.02). No such association was detected for third molars in the lower jaw. Third molars were not associated with masticatory muscle pain, migraine or other types of headache. CONCLUSIONS: Impacted maxillary third molars might be a cause of chronic orofacial pain. Thus, physicians should consider the eruption/impaction status of third molars in their decision-making process when treating patients who complain of orofacial pain.

RESUMO

OBJECTIVE: This study was aimed to delineate the prevalence, clinical, and 3-dimentional radiographic characteristics of adult supernumerary teeth (ST found) in a Chinese non-syndromic, dental population. MATERIALS AND METHODS: Medical records and cone beam computed tomography (CBCT) images were utilized to identify adult patients with ST in a tertiary referral dental hospital between June 2012 and December 2018. CBCT scan coupled with 3-dimentional reconstruction was used to characterize the detailed location, morphology, orientation of ST, and their relationship with adjacent teeth and neighboring structures. All relevant information regarding age and gender of patients, morphology, and 3-dimentional topography of ST as well as ST-associated complications were recorded and statistically analyzed. RESULTS: A total number of 1149 ST was identified in 921 eligible patients screened from 60,104 subjects with the prevalence of 1.5%. Male patients outnumbered females with a gender ratio of 1.76:1. The majority of ST was single, located in the maxilla, especially the maxillary central incisor region. Most ST were conical shape, inverted orientation, and impacted. ST-associated complications including impaction or root resorption of adjacent teeth, and cystic/tumor-like lesions were totally found in 13% ST and significantly associated with location, orientation, and morphology of ST. CONCLUSIONS: Most ST in Chinese adults were conical, inverted, impacted, and located in the maxillary central incisor region, and associated with various complications. Our findings offer valuable information concerning the prevalence, clinical, and radiographic characteristics of ST in non-syndromic Chinese adults. CLINICAL RELEVANCE: These findings are beneficial for clinicians to comprehensively understand the incidence, pathogenesis, and clinical management of ST.

RESUMO

Objetivo: Evaluar la prevalencia y el patrón de reten- ción ósea de los terceros molares en pacientes que concurrie- ron a un servicio de urgencias y orientación de pacientes en el Área Metropolitana de Buenos Aires. Materiales y métodos: Se realizó un estudio obser- vacional retrospectivo en el que se evaluaron radiografías pa- norámicas de pacientes mayores de 18 años que concurrieron a un servicio de urgencias en el Área Metropolitana de Bue- nos Aires. Resultados: Fueron evaluadas 949 radiografías pano- rámicas. En 347 casos, se presentó al menos un tercer molar retenido. Entre los 1878 terceros molares registrados, hubo 768 retenidos (41%). Según la clasificación de Gregory y Pell, la ubicación más frecuente de los terceros molares retenidos inferiores fue la IIA (28%), y de los superiores, la C (54%). La angulación más frecuente fue la vertical (62%). En el 9% de los casos estudiados, se encontró una radiolucidez asociada al tercer molar mayor a 3 mm. No se encontró diferencia signifi- cativa en la prevalencia de retención según el sexo. Conclusiones: La prevalencia de retención fue mayor en el maxilar inferior que en el superior. La posición más fre- cuente fue la vertical. No se encontraron diferencias significa- tivas en cuanto a la distribución según el sexo (AU)


Aim: To evaluate the prevalence and pattern of bone re- tention of third molars in patients attending a patient orienta- tion and urgency service in the metropolitan area of Buenos Aires City. Materials and methods: This retrospective observa- tional study was conducted in a department of dental urgency in the city of Buenos Aires where we evaluate radiografic or- topantomograms. Results: 949 panoramic radiographs were evaluated. In 347 there was at least one third molar retained. Within the 1878 third molars registered, there were 768 retained (41%). In the lower retained third molars the most frequent location corresponded to the IIA location (28%) and in the upper ones it corresponded to the C location (54%) according to Gregory & Pell. The vertical position was the most frecquent (62%). A radiolucency associated with the third molar greater than 3 mm was found in 9% of the cases studied. No significant difference was found in the prevalence of retention according to sex. Conclusions: The prevalence of retention was higher in the lower than in the upper jaw, the vertical position being the most frequent. No significant difference was found in the distribution by sex (AU)

RESUMO

OBJECTIVES: The objective of this article is to establish a large sample-based prediction model for maxillary canine impaction based on linear and angular measurements on panoramic radiographs and to validate this model. MATERIALS AND METHODS: All patients with at least two panoramic radiographs taken between the ages of 7 and 14 years with an interval of minimum 1 year and maximum 3 years (T1 and T2) were selected from the Department of Oral Health Sciences, University Hospital Leuven database. Linear and angular measurements were performed at T1. From 2361 records, 572 patients with unilateral or bilateral canine impaction were selected at T1. Of those, 306 patients were still untreated at T2 and were used as study sample. To construct the prediction model, logistic regression analysis was used. RESULTS: The parameters analyzed through backward selection procedure were canine to midline angle, canine to first premolar angle, canine cusp to midline distance, canine cusp to maxillary plane distance, sector, quadratic trends for continuous predictors, and all pairwise interactions. The final model was applied to calculate the likelihood of impaction and yielded an area under the curve equal to 0.783 (95% CI [0.742-0.823]). The cut-off point was fixed on 0.342 with a sensitivity of 0.800 and a specificity of 0.598. The cross-validated area under the curve was equal to 0.750 (95% CI [0.700, 0.799]). CONCLUSION: The prediction model based on the above mentioned parameters measured on panoramic radiographs is a valuable tool to decide between early intervention and regular follow-up of impacted canines.

RESUMO

PURPOSE: To investigate and compare the clinical application of flap or flapless buccal surgery on the extractions of mesially/horizontally impacted 3rd molar with high or medium position impact in terms of the average surgery duration, number of root fracture, postoperative pain degree and duration, postoperative swelling degree and duration, degree of limitation of mouth opening. MATERIALS AND METHODS: The present study was conducted of 28 patients who were examined and underwent bilateral extraction of impacted mandibular 3rd molar. One molar was randomly extracted with flap buccal surgery (Control Group, CG) and the other one with flapless buccal surgery (Experimental Group, EG) in the same patient. RESULTS: Gender distribution, average age, average surgery duration and number of root fracture between the two groups were not statistically significant (P>0.05). The postoperative pain degree, swelling degree and degree of limitation of mouth opening were all significantly greater in CG than EG. Moreover, the duration of postoperative pain and swelling were all were all significantly longer in CG than EG (0.01

RESUMO

OBJECTIVE: We compared the effect of lingual-based triangular flap with buccal-based triangular flap on postoperative complications in impacted third molar surgery. MATERIAL AND METHODS: Thirty patients aged between 18 and 36 (mean age 19.65±2.14) were included. They all had bilateral impacted third molars. We used buccal-based triangular flap on a randomly selected side (Group 1) and lingual-based triangular flap on the other side (Group 2). We evaluated pain during 7 days after the surgery; swelling and trismus on postoperative 2., 7. and 14. days; wound dehiscence and alveolar osteitis incidence on postoperative 7. and 14. days. RESULTS: Pain was significantly higher in Group 2 during 7 days postoperatively (P<.05). Trismus and swelling were also more prominent in Group 2 on postoperative days 2 and 7. In Group 2, the duration of the surgery in was longer than Group 1 (P<.05). In Group 1, 17 patients (56.7%) had wound dehiscence and 6 patients (20%) in Group 2 (P<.05). No alveolar osteitis developed in either groups. CONCLUSION: The buccal-based triangular flap seems better with regard to postoperative pain, swelling and trismus. On the other hand, the lingual-based triangular flap had a lesser incidence for wound dehiscence.

RESUMO

Objectives: To assess the frequency and reasons for delayed diagnoses of displaced/impacted canines and to determine to what extent this causes complications. In addition, to assess whether any preventive measures were taken.Materials and methods: Patients with displaced/impacted canines that were diagnosed late; i.e. at an age ≥12 years, were consecutively collected during September 2015 to September 2018 in the County Region of Halland, Sweden. Additionally, patients who had undergone surgical exposure or extraction of an impacted canine during the same time period were identified.Results: Eighty-four individuals (58% girls, 42% boys, mean age: 13.75 ± 1.53 years) with 114 impacted canines were detected among 33,488 adolescents aged 12-20 years, resulting in a low-frequency rate: 84 cases per 100,000 persons. Eighty-six percent of the delayed canines were in the maxilla, the rest in the mandible. Deciduous canines were present in 80% of the cases. Most patients had a dental examination at 9-11 years of age but the position of the canine was not documented in many cases. Root resorption of adjacent teeth was noticed in 13% of the patients. No new clinical procedures or guidelines were developed.Conclusions: The frequency of delayed diagnoses of displaced/impacted canines was low. To minimize the frequency even more, documentation of the canine position during the dental examination should not be forgotten at ages 9-11. Presence of the deciduous canine can be used as a clinical indicator that the position of the permanent canine needs to be investigated.

RESUMO

Objective: The objective of this study is to determine the incidence of impacted teeth and the frequency of pathologies they caused by cone beam computed tomography (CBCT) retrospectively. Materials and Methods: In this study, 608 patients' CBCT images were analyzed retrospectively. Detected impacted teeth were classified as incisor, canine, premolar, molar, third molar, and supernumerary teeth. The pathologies caused by impacted teeth are classified as cysts or tumors, tooth decay, root resorptions, and periodontal bone loss. Results: Impacted teeth were detected in 34.37% of the 608 CBCT images included in the study. The distribution of impacted teeth was 9.4% incisor, 29.4% canine, 9.9% premolar, 2.9% molar, 9.3% supernumerary, and 39.9% third molar teeth. Approximately 63.7% of the impacted teeth caused a pathology. The pathology that was most commonly caused by impacted teeth was periodontal bone loss (44.4%), and respectively others were root resorptions (33.3%), cysts or tumors (8.6%), and tooth decay (2.3%). The most common cause of this pathology was right mandibular third molar teeth. Conclusion: Impacted teeth were common and they often caused a pathology. CBCT is a useful device to assess the impacted teeth. When the impacted teeth are evaluated, each tooth should be assessed within itself. If the impacted teeth are not caused by pathology, they can be kept under control.
