The Enigma Unveiled: Expansile Compound-complex Odontoma in the Anterior Maxilla of a Teenager.

Aim and objective: The objective of this case report is to offer insight into an expansive compound-complex odontoma located in the anterior maxilla of a 15-year-old male. The focus is placed on the importance of early detection and the progressive comprehension of odontomas. Background: Odontomas are common odontogenic lesions that are frequently discovered during examinations for delayed tooth eruption. There are two distinct classifications for odontomas-compound odontomas and complex odontomas. With its own each set of characteristics. A timely diagnosis is critical for avoiding complications. Case description: A male individual aged 15 years exhibited an expansive compound-complex odontoma located in the anterior maxilla. The clinical examination showed delayed tooth eruption and asymptomatic swelling. The radiographic images showed a radiopaque mass with tooth-like structures and radiolucent borders affecting the surrounding dentition. A surgical excision procedure was conducted, followed by a subsequent histopathological examination confirming the diagnosis of compound-complex odontoma. The patient continued orthodontic treatment after a 1-year follow-up without recurrence. Clinical significance: This case emphasizes the importance of regular dental exams in detecting odontomas early. This observation also highlights the growing understanding of odontomas as hamartomatous odontogenic malformations and the challenges of diagnosing them clinically. Additional molecular investigations are required to facilitate the classification and elucidation of genetic factors. How to cite this article: Alhazmi YA.

Immediate loading of implants inserted through impacted teeth in the aesthetic area: A retrospective study with a mean follow-up period of 7 years.

PURPOSE: To evaluate the survival and success rate of and the incidence of complications affecting implants inserted and immediately loaded in sites where an impacted tooth was present in the maxilla. MATERIALS AND METHODS: A total of 10 patients were treated and 14 implants were inserted, 4 in healed sites and 10 in extraction sites. The implant site preparation started in the crestal bone and continued in the enamel and dentine of the impacted tooth. The radiographic depth of implant penetration into the impacted tooth, peri-implant soft tissue and hard tissue condition at the 1-year follow-up and the last follow-up appointment, marginal bone loss at the 1-year follow-up and the last follow-up appointment, and the final aesthetic result were evaluated. RESULTS: The implants healed uneventfully with an adequate hard and soft tissue response and no adverse clinical or radiographic signs or symptoms. They were in function for a minimum of 3 and a maximum of 11 years (mean 7.2 years). CONCLUSION: Although further studies with a larger sample size are required to validate this unconventional approach, it can be considered a valuable clinical option to replace teeth in an area of impaction.

A comparative evaluation of the effect of addition of 8†mg dexamethasone to 2% lignocaine with adrenaline in mandibular third molar surgery: a split mouth randomised double blind study.

Background: Impacted lower third molar surgeries involve trauma in a highly vascularized zone with loose connective tissue leading to inflammatory sequelae including postoperative pain, swelling, trismus and generalised oral dysfunction during the post-operative phase. In minor oral surgical procedures, an all-inclusive method to protract anaesthesia and reduce the inevitable post-operative sequelae is yet to be explored substantially. Aim: To evaluate the efficacy of dexamethasone added to local anaesthetics in extending the depth and duration of anaesthesia and decreasing the postoperative complications after surgical removal of impacted third molars. Methodology: A controlled, randomized, split-mouth, double-blind prospective study involving lower third molar surgery was performed in 35 patients wherein the test group (Group I) received 8 mg dexamethasone added to 2 ml of 2% lignocaine with epinephrine and the control group (Group II) received 2 ml of sterile water added to 2 ml of 2% lignocaine with epinephrine. Onset and duration of anaesthesia were evaluated; followed by evaluation of pain, swelling and trismus for 7 days post-surgery, using independent t-test and ANOVA for repeated measures. Results: Test group had a faster onset of anaesthesia by 69 s and a lengthier duration of 128.4 min (p < 0.001). Pain scores (Visual Analogue Scale) in the first 24 h were 4.9 and 7.5 in the test and control group respectively (p < 0.001). The average dosing of analgesics until postoperative day 7 in the test and control group were 12.6 and 18.4 respectively (p < 0.001). The swelling was significantly lesser in the test group, in addition, trismus was significantly lesser by 1 cm on postoperative days 1 and 2 and 0.2 cm on day 7. Conclusion: The addition of dexamethasone to lignocaine in the nerve block reduces the time of onset and significantly prolongs the duration of anaesthesia with decreased pain, swelling and trismus. Steroids mixed directly with the local anaesthetic agent can minimise the post-operative sequelae associated with third molar surgery with a single needle prick.

Evaluation of complications and quality of life of patient after surgical extraction of mandibular impacted third molar teeth.

BACKGROUND: The aim of our study is to evaluate the postoperative complications after the extraction of impacted third molar teeth and to investigate the effects of these complications on the quality of life of patients. METHODS: Demographic, clinical, and radiological evaluations were conducted, covering factors like age, gender, and tooth position. Clinical measurements, pain and edema assessments, and quality of life evaluations through OHIP-14 scores were performed. Preoperative and postoperative mouth opening, trismus, alveolitis and dehiscence were evaluated. RESULTS: A total of 100 patients were included in our study. No significant gender-based differences were found in measurements, pain, or swelling. There was no statistically significant difference between the preoperative and postoperative results of difference A-C, difference B-E, difference A-D, and difference mouth opening. Procedure duration correlated positively with age, alveolar osteitis, trismus, and swelling. Postoperative quality of life, assessed by OHIP-14, demonstrated a negative correlation with age and trismus. It was observed that the gender and the tooth positions of the patients had no effect on the severity of postoperative pain and edema. CONCLUSIONS: As the age of the patients increases and the duration of the procedure increases, the rate of postoperative complications increases and it is concluded that the quality of life decreases significantly.

Awareness of patients with impacted teeth about impacted teeth in Turkey: A questionnaire study.

Objective: The aim of this study is to evaluate the knowledge and awareness levels of patients who have at least one impacted tooth and who had previously applied to the dentist. Study design: This study was conducted in patients aged 15 years and older who applied to Ordu University Faculty of Dentistry for routine examination and agreed to fill out the questionnaire form. A total of 325 people participated in the survey conducted to determine the awareness of patients applying to the faculty of dentistry about their existing impacted teeth. A Pearson's chi-square test was used for hypothesis testing when expected frequencies exceeded 5. Results: It was determined that 56.9 % (185) of the participants were aware of their existing teeth, while 43.1 % (140) were not aware. When the patients were evaluated according to the institutions they had visited, it was seen that the group who were most aware of the presence of impacted tooth were those who apply to the faculty of dentistry (74.4 %). The rate of being informed by dentists in the institutions that they had previously visited was higher in patients with university or post-university graduates (p < 0.05). The most common information given by the dentists to the patients about their impacted dental problems was that the tooth should be followed up (40.4 %), while the removal of the tooth constituted 28.4 % of the information given. Conclusion: This study showed that although patients are aware of their existing impacted teeth, their level of knowledge about the risks it may pose is low. For a healthy oral care and health, patients should be adequately informed about impacted teeth.

[Microanatomy features in third molars roots adjacent to mandibular canal]. / Osobennosti anatomii kornei tret'ikh molyarov i nizhnechelyustnogo kanala pri ikh tesnom prileganii.

THE PURPOSE: Of the study is to reduce the risk of postoperative neuropathy of the inferior alveolar nerve by improving diagnostic methods, assessment of individual topographic and anatomical features and extraction technique of impacted teeth adjacent to the mandibular canal. MATERIALS AND METHODS: According to the CBCT examination, orthopantomography and macroscopic examination of removed third molars roots (n=140) the relative position of the mandibular canal and the roots of the third molars were studied. RESULTS: Three variants of close mandibular canal and third molars position have been identified. In the lateral and apical nerve position, the root surface depressions were detected. With inter-radicular position fit, the mandibular canal and the nerve bundle form a «bed¼ in between impacted tooth roots. CONCLUSION: The injury of neurovascular bundle prognosis during extraction with an interadicular mandibular position depends on roots anatomy and their convergence degree. If the interradicular distance is less than the diameter of the mandibular canal, nerve injury during tooth extraction is inevitable, in such cases coronectomy is indicated.

[Classification of lower impacted third molars position and their interrelationship with mandibular canal]. / Klassifikatsii vidov retentsii nizhnikh tret'ikh molyarov i ikh anatomicheskogo vzaimoraspolozheniya s nizhnechelyustnym kanalom.

Classification of lower Impacted third molars position and their interrelationship with mandibular canal have a great scientific, theoretical and practical importance. An attempt to systematize and classify all anatomical impacted third molars position has been made by many authors. Based on our scientific literature search, we found: 8 impacted third molars classifications, 7 third molars and mandibular canal interposition classifications, as well as 5 classifications of mandibular canal anatomical branching variants. Most classifications are proposed by the author to predict third molar eruption perspective, determine level of operation complexity and prevent mandibular canal damage. New clinical classification development of impacted third molars interrelationship with mandibular canal, which combined the radiological PR, CBCT criteria, neurovascular bundle trauma prognosis, and operative technic choice can be actual.

Is There a Relationship Between Unilateral/Bilateral Impacted Maxillary Canines and Nasal Septum Deviation?

Introduction A deviated nasal septum may be associated with some dentofacial deformities. The aim of the study was to determine whether there is a relationship between some craniomaxillary features of unilateral and bilateral maxillary impacted canines and nasal septum deviation. Methods This is a retrospective study consisting of cone beam computed tomography (CBCT) images of 51 patients. All patients were divided into three subgroups: unilateral maxillary impacted canines (UMIC) (n=19) bilateral maxillary impacted canines (BMIC) (n=15), and control group (MC) (n=17). The septal deviation angle and some angular and dimensional measurements were performed. Differences in linear and angular measurements between the groups were analyzed using One-way ANOVA and the Kruskal-Wallis test. Pearson's correlation analysis was performed to determine the relationship between the septal deviation angle, septal deviation direction, nasal floor angle, and other parameters, and multivariate linear regression analysis was performed to determine the effect of variables in the septal deviation angle. Results Bilateral or unilateral position of the impacted canines was found to be effective on septal deviation. The septal deviation angle and the nasal floor angle values were found to be significantly higher in the UMIC and BMIC groups (p<0.001) than in the MC group. Maxillary width was found to be significantly lower in the BMIC group compared to the UMIC (p<0.01) and MC group (p<0.001). Septal deviation angle was positively correlated with septal deviation direction and nasal floor angle (p<0.001). Palatal width and nasal floor angle were found to be negatively correlated (p<0.05), and palatal depth and septal deviation direction were found to be positively correlated (p<0.01). Groups and septal deviation angle, septal deviation direction, and nasal floor angle were found to be negatively correlated (p<0.001). The multivariate linear regression analysis revealed an association between septal deviation angle, group (p<0.01), and nasal floor angle (p<0.05). Conclusion Bilateral or unilateral position of the impacted canines was found to be effective on septal deviation. The septal deviation angle values were found to be higher when the maxillary impacted canine was unilateral. Unilateral or bilateral positions of the impacted canine and the nasal floor angle were found to be factors affecting the formation of septal deviation.

Characteristics of Unilaterally Impacted Maxillary Canines and Effect on Environmental Tissues: A CBCT Study.

BACKGROUND: The prognosis of orthodontic treatment for a patient with impacted canine teeth can be affected by many factors and understanding some of the characteristics of impacted teeth can increase the effectiveness and reduce the duration of treatment. This study aims to explore the effects of positions and dentoalveolar morphological characteristics of impacted maxillary canines on the prognosis of orthodontic treatment. METHODS: In this study, forty-six adolescent individuals who applied for treatment of impacted teeth were divided into three groups: CC (no impacted maxillary canine group), BC (unilateral buccally positioned impacted maxillary canine group), and PC (unilateral palatally positioned impacted maxillary canine group). The impacted canine and adjacent teeth were evaluated in terms of position, angulation, inclination, mesiodistal and buccolingual widths, root length, dilaceration angle, and root resorption. RESULTS: The mean values of U3 Ang (angulation of the maxillary impacted canine) and U3/U2 angles (maxillary impacted canine and lateral incisor angle) were statistically significantly higher in the BC and PC groups (p < 0.001). The mean values of U2 RL (lateral incisor root length) and U3 RD (canine root dilaceration angle) were statistically significantly lower in the BC and PC groups. CONCLUSIONS: The results of this study suggest that shorter root lengths and increased angulation values may lead to the ectopic eruption of canines. The higher canine angulations in the PC group increase the degree of root resorption.

Assessment of the Relation Between Patterns of Third-Molar Impaction and Blood Group: A Retrospective Study.

Background The prevalence of impacted third molars is high in the global general population. The etiology of impacted third molars is not fully understood, but it is thought to result from combined genetic and environmental factors. Some studies have suggested a link between the blood group and the risk of impacted third molars. This study aimed to investigate the association between the blood group and the presence of impacted third molars and its pattern. Method A total of 856 panoramic radiographs were included in the study. The third molars were evaluated for the pattern of third-molar impaction and blood characteristics recorded as ABO group and presence or absence of Rhesus antigen. Results The results showed no significant association between the blood group and the presence of impacted third molars. The prevalence of at least one impacted the third molar was 34.6%. The most common angulation of impacted third molars was vertical (V) (45.1%), followed by mesioangular (MA) (33.7%), distoangular (DA) (13.8%), and horizontal (H) (7.4%). There was no significant association between the blood group and the number of impacted third molars nor between the blood group and the angulation of the impacted third molars. Conclusion This study suggests that the blood group is not a major factor in the development of impacted third molars. However, further studies with larger sample sizes are needed to confirm these findings.

Influence of the maxillary dimensions and anterior teeth anatomy on the buccal impaction of upper permanent canines: A three-dimensional case-control study.

OBJECTIVE: The diagnosis of impacted upper permanent canines (IUPC) is a relatively common clinical finding. The aim of this study was to investigate the association of the buccal impaction of upper permanent canines with their dimensions and the maxilla bone base. MATERIAL AND METHODS: Cone beam computed tomography files of 66 patients were allocated into: impaction group (ICG/n=33/mean age 15.7±3.9 years), with 44 impacted canines by the buccal side; control group (CG/n=33/mean age 15.66±3.99 years), matched for age and sex, with 66 canines normally erupted. The following measurements were obtained from ICG and CG groups: linear and volumetric canine dimensions, linear measurements of upper permanent central and lateral incisors, measurements of the anterior perimeter and transverse segments of the maxilla. Independent Student's t-test was used for intergroup analysis with correction of Bonferroni (α=0,005). RESULTS: Higher values were found in the means of the variables regarding to the anterior teeth crowns in the ICG group, however, without a significant difference (P<0,005). The upper arch anterior perimeter of the individuals with canine impaction through buccal area was reduced compared to CG (P=0.001). CONCLUSIONS: It can be concluded that individuals with upper buccal impacted permanent canine showed a significantly smaller anterior perimeter of the maxillary arch when compared to the control group. Although greater canine mesiodistal diameter was found in this group, there is no statistical association with the occurrence of this condition.

Influence of the maxillary dimensions and lateral incisor anatomy on the palatal impaction of maxillary permanent canines: A three-dimensional case-control study.

OBJECTIVE: The diagnosis of impacted upper permanent canines (IUPC) is a relatively common clinical finding. The aim of this study was to investigate associations between the upper permanent canines palatal impaction, lateral incisors morphology and the maxilla bone base. MATERIAL AND METHODS: Cone-beam tomography files from 62 subjects were divided into 2 groups: impaction group (ICG/n=31; mean age 14.3±2.4) with 45 canines impacted on the palatal side and age- and sex-matched control group (CG/n=31; mean age 14.3±2.3), with 62 normally erupted canines. Linear and volumetric measurements of the lateral incisors, linear transversal measures and the maxillary anterior perimeter were taken. Independent Student's t-test was used for intergroup analysis with correction of Bonferroni. RESULTS: Significant differences were found for crown length and root diameter (buccal-palatal) (P<0.005). The maxillary anterior perimeter in the ICG was reduced in relation to the GC but not significantly (P=0.008). The transverse skeletal variables of the maxilla were equivalent in the intergroup comparison (P>0.005). CONCLUSION: Smaller dimensions in the crown length and in the upper permanent lateral incisors root buccal-palatal diameter were associated with the impaction of upper permanent canines on the palatal side. The maxillary transverse morphology did not show any association with the occurrence of this condition.

[Dental implant placement in the area of ectopic and impacted teeth]. / Dental'naya implantatsiya v oblasti retenirovannykh i distopirovannykh zubov.

Clinical Assessment of Immediate Autotransplantation of Mandibular Third Molars: An In Vivo Study.

INTRODUCTION: Transplanting a tooth from one area of the mouth to another is known as autogenous tooth transplantation. It is a great choice for restoring young patients' teeth with developing alveolar bone because it uses the patient's own tooth as the replacement rather than a false one. This study aims to evaluate pain, infection, mobility, resorption, ankylosis, and success rate in the replacement of mandibular non-restorable molars through an immediate autotransplantation of the nonfunctional impacted mandibular third molar. MATERIALS AND METHODS: In this in vivo study, 20 patients between the ages of 22 and 50 were selected. The cases in which the first or second mandibular molar was nonrestorable and had an impacted third molar for transplantation were selected. In all the cases, the nonrestorable molar was extracted and replaced with a nonfunctional, impacted third molar. All the cases were evaluated for pain, infection, mobility, ankylosis, and resorption at the postoperative second week, one month, third month, and six months. The pain was assessed on the visual analog scale (VAS), infection was assessed by the presence of purulent discharges, mobility was assessed on a clinical examination of tooth movements, ankylosis was seen radiographically as the obliteration of the periodontal ligament space, and the absence of the lamina dura and resorption were seen radiographically as radiolucency on the root surface. All the readings were tabulated and statistically analyzed. RESULTS: Pain was seen to be maximal at two weeks and minimum at six months. Infection was not seen at all time intervals. Mobility was reduced with time. There was no significant ankylosis or resorption. Out of the 20 cases, four patients required extractions due to resorption and grade 3 mobility. One patient showed ankylosis. The success rate of the autotransplantation was 75%. Fifteen patients showed well-defined lamina dura without ankylosis or resorption. CONCLUSION: Autotransplantation is a valuable tooth replacement option and more economical, especially when provided with proper case selection.

Surgical removal of third molars in a young adult: review of indications and surgical techniques.

Germectomy is a surgical method most typically performed in young adults. The indications for treatment are controversial. The purpose of this review was to determine the correct indications for germectomy and to discuss the advantages and disadvantages of the procedure. We reviewed the surgical techniques (anesthetic methods, patient preparation, and flap designs) and complications. Germectomy for orthodontic purposes is a common indication for surgical removal of tooth germ among young patients. Several studies have supported removal at an earlier age to produce fewer surgical complications. Several surgical techniques have been described in the literature.

Case series and technical report of nasal floor approach for mesiodens.

Objectives: This case series aims to introduce the nasal floor approach for extracting inverted mesiodens. Materials and Methods: Through a retrospective chart review between January 2022 and February 2023, we included the mesiodens patients using nasal floor approach, and analysis the location of mesiodens from the anterior nasal spine (ANS), total operation time, and complications. Results: Each mesiodens was located 10 to 12 mm from the ANS and was covered with a cortical layer of the nasal floor. All mesiodens were successfully extracted without exposing the adjacent incisors or nasopalatine nerve within 30 minutes from draping to postoperative dressing. Conclusion: The nasal floor approach is an efficient extraction method that reduces bone removal and prevents anatomical damage while removing the mesiodens just below the nasal floor bone.

Analgesics effect of local diclofenac in third molar surgery: a randomized, controlled trial.

OBJECTIVES: This study aimed to evaluate the effect of locally diclofenac application on postoperative pain, sequalae, and adverse effects following mandibular third molar (MTM) surgery. METHODS: A randomized, crossover, double-blind, controlled trial was conducted in 20 patients who required surgical removal of bilateral symmetrical impacted MTM at two separate appointments. The 40 MTMs were randomly allocated to two groups. One side was assigned 0.1% w/v diclofenac sodium as the diclofenac group. The contralateral side was assigned phosphate-buffered saline (PBS) as the control group. Postoperative pain intensity was measured by visual analogue scale (VAS), where the time when the first pain emerged, the time to first rescue medication, pain at 6 and 24 h after surgery, and the total number of analgesics consumed were recorded. Postoperative swelling and trismus were assessed on postoperative days 2 and 7. The differences of continuous outcomes between two groups were analyzed by paired t-test or Wilcoxon signed-rank test. RESULTS: VAS scores were significantly lower when the first pain emerged and 6 h after surgery in diclofenac group (p < 0.05). The onset of pain in the diclofenac group was significantly longer than in the control group (p < 0.05). Two patients reported mild nausea and dizziness in the diclofenac group. CONCLUSION: This study demonstrates the analgesic effectiveness of 0.1% local application of diclofenac within 6 h postoperative with few side effects. CLINICAL RELEVANCE: Locally diclofenac application is an alternative of postoperative analgesic in MTM surgery which provides pain-free periods within 6 h.

Palatal approach for surgical removal of mesioangularly impacted maxillary third molar - a pilot study.

OBJECTIVE: This study aimed to investigate the application of the palatal approach for surgical removal of IMTM, and to evaluate its success rate, surgical duration, postoperative outcomes, and incidence of complications. METHOD: Patients with mesioangularly IMTM (Archer Classification Class B) in the none-buccal position to the adjacent second molar, which were indicated for surgical removal, were enrolled in this study. The patients were assigned into two groups according to the surgical approach: the buccal or palatal approach. The impacted tooth positions, diagnosis, past dental and medical history, and radiographic examination were recorded pre-operatively. The duration, surgery details, and surgical complications were documented during the surgery. RESULT: 40 teeth were enrolled in our study. All teeth were removed completely. The operation time was significantly shorter in the palatal approach group compared to the buccal approach group (13.3 ± 2.8 min vs. 22.3 ± 5.5 min, P<0.001). The incidence of traumatic ulcers of the lips was significantly higher in the buccal approach group than in the palatal approach group (7/20 vs. 0/20, P = 0.008). CONCLUSION: It is more efficient to perform surgery with a palatal approach if a Class B mesioangularly IMTM is located in the non-buccal aspect of the adjacent second molar.
