Treatment options for impacted maxillary canines and occurrence of ankylotic and resorptive processes: a 20-year retrospective study.

BACKGROUND: This 20-year retrospective study aimed to evaluate the treatment methods used in patients with impacted maxillary permanent canines and to determine the occurrence of ankylotic and resorptive processes and their association with potential risk factors. METHODS: The cohort consisted of 351 consecutive Caucasian patients (120 males and 231 females, mean age 18.4 and 19.9 years, respectively) with 420 impacted maxillary permanent canines. CT and CBCT findings were subsequently confirmed during surgery. Statistical analyses were performed by the generalized linear models, Pearson x2 and Fisher exact tests using the statistical programs R and Statistica v. 14. RESULTS: A total of 273 (65.0%) impacted canines were aligned in the dental arch by orthodontic traction after surgical exposure, this treatment was predominant in patients under 20 years of age. Surgical extraction was performed in 115 (27.2%) impacted canines and was more common in older patients. Ankylotic changes were recorded in 61 (14.5%) impacted canines. The probability of ankylosis increased with age, particularly after the patient's 20th year of life (p < 0.001). Patients were 1.2% likely to develop ankylosis at age 15 years, 4.3% at age 20 years, 14.1% at age 25 years, and 96.8% at age 45 years. Invasive cervical root resorption (ICRR) was found in 8 (1.9%) canines. In 4 canines (1.0%), root ankylosis in addition to ICRR was observed. In contrast to ankylosis, whose frequency of occurrence increased with age, the occurrence of ICRR resulting from PDL damage during surgery was more typical in younger patients. Canines in a high position above the root apices of the adjacent teeth, with a horizontal inclination of the longitudinal axis, with the crown located deep in the center of the alveolar bone and with labiopalatal position, should be considered critically impacted canines with a high risk to failure of orthodontic traction. CONCLUSION: In conclusion, the treatment of impacted canines depends mainly on the age of the patient, and the position and inclination of the longitudinal axis of the impacted tooth. To select an adequate treatment method, we recommend CBCT examination, which allows a precise analysis of the position of impacted canines.

Effect of Third Molar Surgery on Sleep Health Parameters of Young Adults: An Observational Study.

Background and Objectives: The role of surgical extraction of the third molar in patients' sleep quality remains unclear, although it is one of the most common oral surgical procedures. The aim of this study is to assess the changes in patient-reported sleep health outcomes after third molar surgery and to investigate any associations between sleep parameters and post-extraction pain. Materials and Methods: Young adults without known comorbidities who were in need of mandibular third molar surgical extraction were included. All participants completed a sleep diary, the Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI) and Athens Insomnia Scale (AIS) questionnaires, which were used to assess sleep habits, daytime sleepiness, sleep quality and insomnia severity one week before and after extraction. In addition, a visual analog scale was completed postoperatively to assess the perception of pain. Results: Out of 75 patients who completed the study protocol, 32 (42.7%) were males and 43 (57.3%) were females, with a mean age of 24.01 (±3.43) years. Postoperatively, statistically significant higher scores were observed for PSQI [4.85 (±2.32) before vs. 5.39 (±2.75) after, p = 0.041], AIS [5.56 (±3.23) before vs. 6.91 (±4.06) after, p < 0.001] and average weekly number of nocturnal awakenings [2.01 (±3.72) before vs. 4.19 (±5.20) after, p < 0.001] but not for ESS, average weekly sleep duration and average weekly sleep onset latency. Pain perception was increased in patients who slept worse on almost all seven postoperative days, although this did not reach statistical significance. Conclusions: Third molar surgery impacts sleep quality and insomnia severity in the first week after extraction, while there is no effect on daytime sleepiness. The worsening of subjective sleep symptoms after extraction may be associated with an increased perception of pain.

The effect of hyaluronic acid addition to collagen in reducing the trismus and swelling after surgical extraction of impacted lower third molars: a split-mouth, randomized controlled study.

BACKGROUND: Removal of impacted third molars is associated with postoperative complications such as pain, swelling, ecchymosis, trismus, infection, and hematoma. Thus, contemporary surgery aims to reduce complications by applying collagen or hyaluronic acid in the socket after extracting the impacted mandibular third molars. This study aimed to study the efficacy of hyaluronic acid (HA) addition to collagen, compared to collagen application alone, on the magnitude of swelling and trismus following impacted mandibular third molar surgery. METHODS AND MATERIALS: A total of 40 impacted molars of 20 participants who had completely bilateral impacted lower third molars were enrolled in this split-mouth, randomized, clinical trial. Randomization was carried out by two opaque envelops; two materials were applied topically in the socket collagen alone or with hyaluronic. The postoperative mouth-opening limitation and swelling rate were assessed on the third and seventh days after the extraction. RESULTS: The mean age was 22.7 ± 3.079 years (75% female and 25% male). Regarding the rate of trismus, the test sides had less values than the control sides on 3rd days (44.03 ± 12.8 vs. 52.14 ± 13.7) and 7th days (19.22 ± 12.8 vs. 32.45 ± 15.3) postoperatively but the difference is only significant on the seventh day (P = 0.005). The swelling scores of the hyaluronic acid addition group were significantly lesser than those of the collagen alone group on the third and the seventh day (P < 0.05) except for the lateral canthus to the angulus mandibulae on the third day (P = 0.133). CONCLUSION: Adding hyaluronic acid to collagen could effectively reduce the severity of facial swelling and trismus following surgical extraction of impacted lower third molars. STATEMENT OF CLINICAL RELEVANCE: Swelling and trismus are the most sequela following impacted third molar surgical extraction. This study showed that applying hyaluronic acid with collagen can reduce the severity of facial swelling and trismus which could be useful in surgeons' daily practice. We should mention that this original article has a preprint edition (44).

Influence of inflammation on bleeding and wound healing following surgical extraction of impacted lower third molars.

OBJECTIVE: This study aimed to investigate the effect of inflammatory states following impacted lower third molar (ILTM) surgery regarding postoperative bleeding and wound healing. METHODS: The study included patients who underwent extraction of ILTMs associated with or without inflammatory conditions. Post-extraction bleeding and wound healing were assessed. In addition, mean grey values (MGVs) of alveolar bone and bone height using an orthopantomography radiograph were analyzed. RESULTS: A total of 376 patients were enrolled; 171 pericoronitis, 51 pulpitis, 44 chronic periapical periodontitis, 36 chronic periodontitis, and 74 control. The bleeding score in the control group was significantly lower than in the periapical periodontitis and periodontitis groups. Excellent wound healing for control, pericoronitis, pulpitis, periapical periodontitis, and periodontitis groups was (78.38%, 35.67%, 70.59%, 70.45%, and 33.33%, respectively). Patients with pericoronitis and periodontitis had significantly poorer wound healing (P < 0.01). The MGV in periapical periodontitis and periodontitis was considerably lower than in the control group. CONCLUSIONS: The inflammatory conditions associated with ILTMs increase the risk of bleeding. So suturing with the placement of local hemostatic agents over a pressure pack alone is recommended. The poorest wound healing was in localized gingival inflammation. Furthermore, MGV was affected by age and was lower with periapical periodontitis.

Genetic Pattern, Orthodontic and Surgical Management of Multiple Supplementary Impacted Teeth in a Rare, Cleidocranial Dysplasia Patient: A Case Report.

Background: Cleidocranial dysplasia (CCD) is a rare, autosomal dominant skeletal dysplasia with a prevalence of one per million births. The main causes of CCD are mutations in the core-binding factor alpha-1 (CBFA1) or runt-related transcription factor-2 (RUNX2), located at the 6p21 chromosomal region. RUNX2 plays important roles in osteoblast differentiation, chondrocyte proliferation and differentiation, and tooth formation. The disease is characterized by clavicular aplasia or hypoplasia, Wormian bones, delayed closure of cranial suture, brachycephalic head, maxillary deficiency, retention of primary teeth, inclusion of permanent teeth, and multiple supernumerary teeth. Materials and Methods: A 22-year-old girl suffering from cleidocranial dysplasia with short stature, narrow shoulders, craniofacial manifestations (short face, broad forehead, etc.) and dental anomalies (different lower dental elements under eruption, supernumerary and impacted multiple teeth, etc.) was examined at our service (Complex Operative Unit of Odontostomatology of Policlinico of Bari). RX Orthopantomography (OPG) and cone beam computed tomography (CBCT) were requested to better assess the position of the supernumerary teeth and their relationships with others and to evaluate the bone tissue. Results: Under eruption was probably caused by dental interferences with supernumerary teeth; hence, extractions of supernumerary upper canines and lower premolars were performed under general anaesthesia. Surgery outcome was excellent with good tissue healing and improvements in the therapeutic possibilities with future orthodontics. Conclusions: The objective of this article is to give an update about radiological, clinical, and molecular features of CCD and to alert the health team about the importance of establishing an early diagnosis and an appropriate treatment in these patients to prevent impacted teeth complications and to offer them a better quality of life.

Randomized controlled trial on the effectiveness of absorbable collagen sponge after extraction of impacted mandibular third molar: split-mouth design.

BACKGROUND: The purpose of this study was to compare the effectiveness of absorbable collagen sponge insertion in tooth extraction sites for socket healing of the impacted mandibular third molar. METHODS: Thirty-six patients with bilateral mandibular impacted third molars based on Pell-Gregory and Winter classification were included in this study. This study was a randomized clinical trial utilizing a split-mouth design with one side assigned as collagen sponge insertion and the other side assigned as the control. Post-operative clinical complications, periodontal integrities, and radiographic outcomes were assessed at 1, 2, and 14-weeks post operatively. RESULTS: Five patients were excluded during the follow-up period due to loss of follow-up. The study was conducted on 31 patients in total. The mean VAS score of collagen sponge insertion side at 1 week post operation was 1.42 ± 1.26, which was significantly lower than the control side (P < 0.05). The mean probing depth of collagen sponge insertion side at 2-week post operation was 5.55 ± 2.28 mm, which was significantly lower than the control side (7.13 ± 1.86; P < 0.05). Other various measurements including radiographic outcomes showed no significant group differences. CONCLUSIONS: Placement of collagen sponge after extraction of mandibular impacted third molar reduced early stage post-operative complications and enhanced initial healing of soft tissues and periodontal defects. TRIAL REGISTRATION: This study was retrospectively registered at the WHO ICTRP platform and Clinical Research Information Service, KCT0003363. Registered 21 Sep 2018.

Equine Standing Surgical Extraction Techniques.

Dental repulsion techniques reported in the past decades have a high incidence of complications. Although the practice of surgical extractions in horses is limited because of the training, instrumentation, and experience required to perform these techniques, veterinarians should be aware these procedures are available, general anesthesia is not required, and when performed by skilled veterinary dentists they have low complication rates. Surgical techniques are often used after failure of other extraction techniques to remove retained tooth root and fragments or to debride chronically contaminated orofacial lesions. However, surgical extractions should be considered during initial treatment planning of all complicated cases.

A "long-standing" malpositioned pacing lead. Long-term follow-up after extraction.

Transvenous pacemaker (PM) catheters can be unintentionally placed in the left ventricle (LV) during the implantation procedure. An 8-year-old girl was discovered with a malpositioned pm wire, seven years after the implant. Trans-thoracic echocardiogram revealed the lead traversing the inter-atrial septum, crossing the mitral valve and embedded in the basal lateral wall of the LV. This is a report of a 14-year long follow-up after the surgical extraction of the malpositioned PM lead.

Sparganosis of the Unilateral Breast: A Case Report.

Sparganosis is a parasitic infection caused by the sparganum, the plercercoid of the genus Spirometra. The preoperative diagnosis of breast sparganosis is difficult in most cases because it is a rare parasitic infection less than 2% of all cases. We report a 62-year-old woman case of breast sparganosis that were confirmed by surgical removal of worms from the right breast. The radiologic images of the patient also revealed characteristic features of breast sparganosis. The patient described the migrating palpable breast mass, which strongly suggested the possibility of breast sparganosis. The treatment of choice and confirmative diagnosis for sparganosis are complete surgical extraction of the sparganum irrespective of infected site. Inspection of the mass site with detailed medical history and radiological examinations are important for preoperative diagnosis of sparganosis patients.

Incisional and port-site hernias following robotic colorectal surgery.

BACKGROUND: The association between extraction site location, robotic trocar size, and the incidence of incisional hernias in robotic colorectal surgery remain unclear. Laparoscopic literature reports variable rates of incisional hernias versus open surgery, and variable rates of trocar site hernias. However, conclusions from these studies are confusing due to heterogeneity in closure techniques and may not be generalized to robotic cases. This study evaluates the effect of extraction site location on incisional hernia rates, as well as trocar hernia rates in robotic colorectal surgery. MATERIALS AND METHODS: A retrospective review of multiport and single incision robotic colorectal surgeries from a single institution was performed. Patients underwent subtotal, segmental, or proctocolectomies, and were compared based on the extraction site through either a muscle-splitting (MS) or midline (ML) incision. Hernias were identified by imaging and/or physical exam. Demographics and risk factors for hernias were assessed. Groups were compared using a multivariate logistic regression analysis. RESULTS: The study included 259 colorectal surgery patients comprising 146 with MS and 113 with ML extraction sites. Postoperative computed tomograms were performed on 155 patients (59.8 %) with a mean follow-up of 16.5 months. The overall incisional hernia rate was 5.8 %. A significantly higher hernia rate was found among the ML group compared to the MS group (12.4 vs. 0.68 %, p < 0.0001). Of the known risk factors assessed, only increased BMI was associated with incisional hernias (OR 1.18). No trocar site hernias were found. CONCLUSION: Midline extraction sites are associated with a significantly increased rate of incisional hernias compared to muscle-splitting extraction sites. There is little evidence to recommend fascia closure of 8-mm trocar sites.

Integrative approach for supernumerary teeth: a single-center retrospective analysis.

OBJECTIVE: The study aims to provide a comprehensive case analysis from a single center, with the objective of clarifying the optimal timing and recommending a preferred treatment strategy customized to the specific presentation of each type of supernumerary tooth (SNT) identified in our research. METHODS AND MATERIAL: A retrospective study was conducted on patients who presented with SNT and were treated through an interdisciplinary at the clinic. RESULTS: 55 patients with 81 SNT of the permanent dentition were analyzed. They included 30 males and 25 females. The dentition status of the patients was as follows: 31 patients with mixed dentition, 0 patients with deciduous dentition, and 24 patients with permanent dentition. The diagnosis of SNT diagnosis was primarily made by general or pediatric dentists and/or orthodontists. Patients were then referred to maxillofacial surgeons for treatment decision. The timing of treatment was mainly determined by the oral surgeon, based on the recommendations of the other specialists involved. Cases involving mal-eruption or malalignment of permanent teeth required both surgical and orthodontic treatment. Patients over 9 years old were treated either under local anesthesia or sedation, while those under 9 years old were treated under deep sedation or general anesthesia A comprehensive investigation of cases involved the utilization of cone beam computerized tomography (CBCT) at the SNT site to facilitate treatment planning. There was a significant correlation between younger age and the preference for treatment under sedation or general anesthesia (p=0.01, t-test). Similarly, a strong association was found between younger age and the need for additional orthodontic treatment (p=0.016, t-test). Cases of surgical removal of SNT at a young age typically did not require orthodontic traction of the permanent tooth, in contrast to cases of late surgical intervention (patients over 11 years old), which often did necessitate such traction. There was a strong tendency for treating supernumerary teeth (SNT) in the maxilla. The proximity of SNTs to vital anatomical landmarks significantly influenced treatment decisions. Patients with SNTs near the mental foramen or the inferior dental canal in the premolar area were exclusively placed under follow-up care (p=0.002, Pearson's chi-square test). However, in the maxilla, the proximity of SNTs to vital structures such as the floor of the nose and the incisive nerve did not affect the treatment approach, and those supernumerary teeth were mostly removed. CONCLUSIONS: A team approach for managing supernumerary teeth (SNT) is recommended. The timing of treatment should carefully consider the advantages and disadvantages of early versus late intervention. Early surgical treatment in cases where eruption is disturbed might result in spontaneous eruption, eliminating the need for orthodontic traction of the permanent teeth.

Surgical Treatment of Facial Abscesses and Jaw Osteomyelitis of Dental Origin Using Extraoral Tooth Extraction in the Domestic Rabbit: A Case Series.

The treatment of facial abscesses of dental origin is difficult as jaw osteomyelitis in rabbits is mainly associated with a thick caseous pus that is particularly difficult to drain. Precise identification of the teeth involved in the infected site with the use of cone beam computed tomography (CBCT) was expected to ensure a favorable surgical treatment plan without a long-term local antibiotic strategy or local marsupialization. The first part of the study compared multi-planar reconstruction (MPR) and 3D reconstruction complemented by a maximum intensity projection filter (MIP). The surgical part of the study included rabbits with documentation of the treatment outcome for a period greater than one month after surgery and having had at least one post-operative CBCT demonstrating the achievement of surgical extraction. MPR is significantly more efficient than MIP techniques for alveolar bone (P < 10-7), spongious bone (P < 10-10) and apical elongation (P < 10-5) parameters. Nineteen of 20 surgical sites gave radiological confirmation of the success of the surgical plan. Eighteen of 20 of the abscess sites were clinically healed within one month. Seven out of 20 of the abscess sites presented evidence of one dental structure regrowth following the CBCT recheck. Two out of these seven cases presented with a concomitant persistent chronic facial fistula. Both cases healed after second-stage surgery to extract the tooth structure. The mean number of teeth extracted was 2.85, and seven of the 20 procedures included one incisor.

Influence of Education on Dental Anxiety and Fear in Mental Disorders after Viewing a Molar Extraction in Three Types of Mental Disorder Compared to Persons with No Mental Disorder.

Objective: The goal of this study is to validate the psychometric properties of the Modified Dental Anxiety Scale (MDAS) and the Dental Fear Scale (DFS) at three different times: seven days before, immediately after, and seven days after watching a video of surgical extraction of a lower third molar in a sample with four strata: anxiety disorder, adjustment disorder, mixed anxiety-depressive disorder, and no mental disorder ages 18-70 in a psychiatric clinic in Malaga. Methods: The Research Ethics Committee of the Virgen Macarena-Virgen del Rocío Hospitals approved the study. After being interviewed by a psychiatrist and subsequently completing the Hamilton Rating Scales for Anxiety and Depression, the participants were divided into 4 strata (60 persons in each). The influence of education level was then analyzed. Results: The scales demonstrated good psychometric properties, with higher MDAS and DFS scores for lower levels of education and mixed anxiety-depressive disorder. Conclusions: Patients who show higher levels of dental anxiety and dental fear will be those with lower education levels, as well as those who suffer from mixed anxiety-depressive disorder.

Efficacy of Hydrocortisone, Povidone-Iodine, and Normal Saline as an Irrigating Solution During Surgical Removal of Impacted Mandibular Third Molars: A Randomized Controlled Trial.

Background The surgical removal of mandibular third molars is one of the most common procedures in dentistry. Researchers have extensively studied the treatment of postoperative sequelae such as pain, edema, trismus, and alveolar osteitis throughout the past six decades. Many approaches have been used to address clinical difficulties after third molar surgery, including various flap designs and irrigating solutions. The aim of this study was to compare the effects of three irrigating solutions, hydrocortisone, povidone-iodine, and normal saline, on pain, trismus, and edema following surgical removal of the impacted mandibular third molar. Methodology The study involved 105 participants who required surgical extraction of mandibular third molars. The patients' ages ranged from 18 to 40 years, and they fulfilled the inclusion criteria. Using a simple random sampling technique, they were divided into three groups (group 1: hydrocortisone, group 2: povidone-iodine, group 3: normal saline). The parameters evaluated were edema, pain, and trismus on the second and seventh postoperative days. All data were input into Microsoft Excel (Microsoft® Corp., Redmond, USA) worksheets and analyzed using Stata 17.0 (StataCorp LLC, College Station, USA). The visual analog scale (VAS) score was used to measure postoperative pain, and postoperative swelling was measured using linear measurements from four fixed anatomical points and compared to preoperative values. To assess trismus, the inter-incisal distance was measured in millimeters with a caliper. A p-value of <0.01 was considered statistically significant. Results The mean VAS score for pain in group 1 was lower than the other two groups. The effect of group 1 was significant on the second postoperative day but insignificant on the seventh postoperative day for swelling. The effect of all three groups on trismus was significant on the second and seventh days. Conclusions Hydrocortisone as an irrigating solution showed promising results in managing postoperative swelling in the first 48 hours, but its effect gradually declined by the seventh postoperative day. Additionally, it was effective in controlling postoperative pain and trismus. This suggests that utilizing hydrocortisone as an irrigating solution, compared to povidone-iodine, has been proven to be a significantly effective option in reducing postoperative pain, edema, and trismus resulting from the surgical removal of impacted teeth.

A Case Study is presented to explore how the organization of Surgical Extraction Teams facilitates field amputations allowing for improved patient outcomes in extreme circumstances.

To Study the Impact of Tooth Sectioning on Postoperative Pain, Swelling and Trismus After Surgical Extraction of Impacted Mandibular Third Molars.

AIM: To study the impact of tooth sectioning on postoperative pain, swelling, and trismus after surgical extraction of impacted mandibular third molars. MATERIALS AND METHODS: The present research was conducted on a sample of 100 individuals who were in good health. The participants had an average age of 28 years and were seeking treatment at the Department of Oral and Maxillofacial Surgery for the extraction of impacted mandibular third molars. The participants were allocated randomly to one of the two experimental conditions. The patients in Group A are receiving a surgical procedure to remove the mandibular third molar without the need for tooth sectioning. The study focuses on patients classified as Group B who are having a surgical procedure for the extraction of the mandibular third molar using dental sectioning. RESULTS: The Group B patients saw a notable decrease in pain intensity on the third and seventh days after the surgery. The mean difference in pain scores was 4.15±0.54 and 1.69±0.11, respectively, indicating statistically significant findings with a p-value of less than 0.05. The study observed statistically significant differences in swelling between the 1st, 3rd, and 7th postoperative days for group II. The mean differences were recorded as 149.85±5.86, 119.25±4.22, and 107.52±, respectively. The significance level was determined to be P<0.05. The study observed that the degree of mouth opening in Group B exhibited a significant rise on the 3rd and 7th postoperative days, with a mean difference of 40.87±3.69 and 43.15±3.29, respectively, as compared to Group A. This difference was found to be statistically significant, with a p-value of less than 0.05.  Conclusion: The findings of our research indicate that the technique of sectioning the tooth is the preferable approach for surgical extraction of impacted third molars, as it effectively reduces the occurrence of post-operative problems.

Microbiological Evaluation of Four Different Suture Materials Used for the Surgical Removal of Impacted Lower Third Molars: A Single-Center Prospective Comparative Study.

Introduction Sutures play a crucial role in the postoperative healing process, as they help approximate wound edges, promote hemostasis, and support tissue healing. The oral cavity harbors a diverse microbial population, and oral surgical procedures can introduce potential pathogens into the surgical site. Understanding the impact of suture material on wound infection rates and the colonization of potentially harmful microorganisms is vital for improving patient outcomes. This study was aimed to evaluate and compare the microbiological properties of prolene, vicryl plus, monocryl, and silk sutures used after the surgical removal of impacted lower third molars. Materials and methods A total of 40 patients requiring surgical extraction of impacted lower third molars were assigned to four groups: prolene, vicryl plus, monocryl, and silk sutures. Surgical extraction of impacted tooth was done, and wound was sutured with the abovementioned four different materials in four groups, respectively. After seven days, the sutures were removed and sent to the microbiology lab for colony count assessment. Total microbial colony count, streptococcus count, and lactobacillus count were assessed. Data was analyzed using IBM SPSS Statistics for Windows, Version 23.0 (Released 2015; IBM Corp., Armonk, New York, United States) with p-values less than 0.05 considered as statistically significant. The one-way analysis of variance (ANOVA) and post-hoc Tukey test were done to compare intergroup relations. Results The microbiological evaluation of the sutures revealed significant differences in bacterial colonization among the four groups. More bacterial quantities were found in the silk group followed by the monocryl, vicryl plus, and prolene groups in the descending order. Prolene demonstrated the lowest incidence of bacterial growth (p<0.001) compared to vicryl plus, monocryl, and silk sutures. Bacterial colony count was highest in the silk group. The predominant bacterial species found in all groups were Streptococcus viridans, Staphylococcus aureus, and Lactobacillus.  Conclusion It was found that prolene and vicryl plus sutures exhibited superior microbiological properties compared to monocryl and silk sutures when used for the surgical removal of impacted lower third molars. The lower incidence and less quantity of bacterial colonization on prolene sutures suggest their potential for reducing the risk of postoperative infection; hence, these sutures can be preferred for oral surgical procedures.

Marsupialization of Dentigerous Cysts Followed by Enucleation and Extraction of Deeply Impacted Third Molars: A Report of Two Cases.

A dentigerous cyst (DC) is a developmental odontogenic cyst that involves the crown or a portion of the crown of an unerupted or impacted tooth. Mandibular third molars are the most commonly implicated teeth in this type of cyst. DC can be asymptomatic and detected by an ordinary radiographic examination. Two massive DC with deeply impacted third molars were treated by marsupialization followed by surgical extraction and enucleation of the residual lining. In both cases, sensation on the lower lip and chin remained normal, and complete bone healing was achieved. Decompression by simple marsupialization and extended follow-up are important roles in bone deposition and reduction of the cyst. Furthermore, surgical extraction can be performed non-traumatically for the cyst-associated tooth, because the surrounding bone is newer and less calcified than mature bone.

Surgical Extraction of Traumatic Lodgment of a Pen Nib Between the Eye and Nasal Bridge of an Infant: A Case Report.

Unintentional eye injuries are common in small children. If left unobserved by parents or caretakers, it is challenging to assess as the kids are in distress and pain. Penetrating trauma in or near the eye requires urgent treatment as it can lead to infection and other complications. Early diagnosis and management help avoid further complications. An 11-month-old female was presented by her parents at a tertiary care clinic with inconsolable crying and swelling over the right eye's upper lid for one day. There was a history of possible trauma with a pen while the child was playing. During the examination, swelling in the right periorbital region between the eye and nasal bridge with the opening of the foreign body tract was noted. A skull X-ray with orbit showed a radiopaque nib of the pen in the right periorbital soft tissue. Emergency surgery was planned under general anesthesia. Surgery was performed and the pen was extracted from the right periorbital soft tissue lying between the eye and nasal bridge. Parents and health care providers, including pediatricians, should assess a crying child with a trauma history carefully even with no apparent clinical findings. Efforts must be done to correlate clinical findings with proper history and other needed investigations.

When dental extractions go wrong: An overview of common complications and management.

The extraction of teeth carries a risk of associated complications, some of which may be predicted, providing an opportunity for them to be prevented or their effects minimised. Prior to embarking on any extraction, the dentist must be confident that they are able to deal with any complication that may arise. This paper provides an overview of the complications of dental extraction which are commonly encountered, considers the factors which predispose to them arising, suggests how the risk of them occurring can be reduced, and describes how they should be managed.
