Evidence-based management of isolated dentoalveolar fractures: a systematic review.

Dentoalveolar (DA) trauma, which can involve tooth, alveolar bone, and surrounding soft tissues, is a significant dentofacial emergency. In emergency settings, physicians might lack comprehensive knowledge of timely procedures, causing delays for specialist referral. This systematic review assesses the literature on isolated DA fractures, emphasizing intervention timing and splinting techniques and duration in both children and adults. This systematic review adhered to PRISMA guidelines and involved a thorough search across PubMed, Google Scholar, Semantic Scholar, and the Cochrane Library from January 1980 to December 2022. Inclusion and exclusion criteria guided study selection, with data extraction and analysis centered on demographics, etiology, injury site, diagnostics, treatment timelines, and outcomes in pediatric (2-12 years) and adult (>12 years) populations. This review analyzed 26 studies, categorized by age into pediatrics (2-12 years) and adults (>12 years). Falls were a common etiology, primarily affecting the anterior maxilla. Immediate management involved replantation, repositioning, and splinting within 24 hours (pediatric) or 48 hours (adult). Composite resin-bonded splints were common. Endodontic treatment was done within a timeframe of 3 days to 12 weeks for children and 2-12 weeks for adults. Tailored management based on patient age, tooth development stage, time elapsed, and resource availability is essential.

Throat packing via nasopharyngeal airway for severe trismus cases requiring surgical intervention under general anesthesia: A simplified and innovative approach.

Throat packing is essential in oral and maxillofacial surgeries to prevent blood and tissue debris aspiration, reducing postoperative complications. Traditional oral route methods are often inadequate, especially in severe trismus cases like Oral Submucous Fibrosis (OSMF), TMJ Ankylosis, and post-traumatic conditions due to limited mouth opening. This study introduces a novel technique using a nasopharyngeal airway (NPA) for throat packing. The method involves inserting a hemostatic dressing through an NPA, ensuring minimal invasiveness and effective airway management. Proper positioning is confirmed with a laryngoscope or fiberoptic scope, and the dressing is secured to prevent dislodgement. This technique is easy, reproducible, and less injurious compared to traditional methods. At our center, throat packing via NPA was performed on 35 patients undergoing surgery under general anesthesia, resulting in high satisfaction and no reported complications.

A screw and wire assisted coronoidectomy procedure: A technical note.

Temporomandibular joint (TMJ) ankylosis and oral submucous fibrosis (OSMF) often exhibit elongated hyperplastic coronoid processes with fibrous attachments to the temporalis muscle. In managing this condition, a vital step involves performing a coronoidotomy or coronoidectomy alongside the primary surgical procedure. While coronoidectomy is preferable due to reattachment issues, its complexity arises from the thickened and elongated coronoid process. Our technical note introduces a screw and wire assisted coronoidectomy method, found to be efficient, replicable, and time-saving.

Correction of Facial Asymmetry due to Different Complex Mandibular Pathologies by Aesthetic Surgical Procedures: A Case Series and Assessment of Quality of Life Following Corrective Surgeries.

Background: A numerous diseases may result in facial asymmetry, one of them is the presence of any condylar pathology. Patients with such condylar pathology resulting in facial asymmetry have a functional, aesthetic and psychological impact on them. The present study aims to identify the effect of corrective surgeries of such cosmetic deformities on the quality of life of the patients. Case Reports: Patients diagnosed with condylar pathologies resulting in facial asymmetry subjected to the corrective surgeries. The quality of life assessment was done preoperatively and 3 months postoperatively, by assessing the oral health using the Japanese version of the Oral Health impact profile (OHIP). A total of 12 patients were operated and assessed with an age ranges of 18-42 years. Seven out of 12 patients were diagnosed with condylar hyperplasia, and five patients were having benign tumor of the mandibular condyle. The mean preoperative OHIP score was 68.25 ± 7.19, which significantly improved to 24.58 ± 4.88 postoperatively. Conclusion: Corrective surgeries of facial deformity dramatically improves the quality of life of the patients.

Ayurvedic and herbal plaque control agents in gingivitis: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Since the effectiveness of ayurvedic and herbal plaque control agents in reducing plaque in gingivitis is inconsistent across multiple trials, we conducted a study to evaluate their overall effect on dental plaque index (PI), gingival index, and bacterial colony counts (CC) of debris in gingivitis patients. MATERIALS AND METHODS: We searched major electronic biomedical databases (PubMed/Medline, CAM-QUEST®, EBSCOhost, Google Scholar, EMBASE, Scopus, and Cochrane Central Register of Controlled Trials) from August 2004 to August 2021 for randomized control trials on gingivitis using ayurvedic, herbal plaque control agents, and oil pulling therapy as interventions. We grouped comparable outcome parameters of similar products and estimated the standard mean difference (SMD) for pooled effect size with 95% confidence intervals (CI) using RevMan 5.4.1 software. Risk-of-bias (ROB) assessment followed the Cochrane Collaboration's recommended approach. RESULTS: We found 554 articles of 2,806 patients after searching of which 41 randomized clinical trials were considered for meta-analysis. Ayurvedic plaque control agents (Plaque index (PI): SMD = -0.52, 95% CI (-0.94, -0.11); CC: SMD = -1.70, 95% CI (-5.06, 1.67)), (Oil pulling therapy: PI: SMD = -0.38, 95% CI (-1.45, 0.68); CC: SMD = -1.04, 95% CI (-2.20, 0.11)), (Herbal plaque control agents: PI: SMD = -0.58, 95% CI (-1.55, 0.39)), (Triphala: PI: SMD = -0.65, 95% CI (-1.32, 0.03)) were found as good as control. Significant reduction in the gingival index and bacterial colony count was also seen. CONCLUSIONS: In addition to conventional dental care, ayurvedic and herbal plaque control agents may help in plaque reduction, gingival inflammation, and bacterial growth. They are safe and may be recommended in community dentistry practices.(PROSPERO registration number: CRD42021274656).

Oral manifestations, risk factors and management strategies of COVID-19 associated mucormycosis in tertiary care hospital.

Background: Mucormycosis (black fungus) is an aggressive, life-threatening infectious disease-causing infiltration and by destroying the surrounding bone and soft tissue through vascular thrombosis and subsequent tissue infarction that may reach the brain with fatal complications. Its outbreak has been assessed around the clock during the recent pandemic as post COVID-19 sequelae. Aims: To assess the risk factors, oral signs and symptoms, investigations, treatment and rehabilitation strategies amongst COVID-19 associated mucormycosis patients in a tertiary care hospital. Methods and Material: An observational, pilot study was carried out amongst 30 active or recent COVID-19 associated mucormycosis patients reporting in the Department of Dentistry of a tertiary care hospital in Bhopal over a period of 6 months. Statistical analysis was done using Kolmogorov-Smirnov test using the Statistical Package for Social Sciences, Version 16 software. Results: Study was done on 30 patients (80% males and 20% females) and their median age was 46 years. Predominant risk factor present was diabetes mellitus (90%) and steroid therapy (60%). Prime oral manifestations were toothache (90%), mobile teeth (83%), draining sinus (53%), palatal ulceration (43%) and para-sinusal pain (37%). Conclusions: Mucormycosis can cause serious oro-facial morbidity and mortality in COVID-19 patients. The current management strategy requires early diagnosis, prompt treatment and oral rehabilitation.

Clinical outcome following conservative treatment of 58 mandibular ameloblastoma patients: a retrospective study.

The aim of this study was to retrospectively analyze the surgical outcome of the patients with mandibular ameloblastoma (MA) with intact inferior cortex and the lingual cortex of the mandible, treated with conservative management in the form of enucleation with peripheral ostectomy, mechanical curettage, chemical cauterization, dredging, and marsupialization. The patients were included with the diagnosis of MA between the age group of 14 to 60 years with their computed tomography (CT) scans showing intact inferior cortex and the lingual cortex of the mandibular walls. Out of 96 cases of ameloblastoma, 58 (61%) were in mandible and 38 (39%) cases in maxilla. We analyzed these 58 patients retrospectively which were operated conservatively between January 2009 and December 2018. The treatment protocol for all the solid variants and the unicystic variants with intact buccal, inferior, and the lingual cortex was enucleation with peripheral ostectomy followed by mechanical curettage, chemical cauterization, and subsequent dredging. This was performed in 90% (n = 52) cases, whereas the treatment protocol for unicystic variants with perforated buccal cortex and intact inferior and lingual cortex was marsupialization followed by the enucleation with peripheral ostectomy, mechanical curettage, chemical cauterization, and subsequent dredging which was performed in 10% (n = 6) cases. Chi square test was applied to the effectiveness of conservative management as outcome variable. The new bone formation along with bony trabeculae was found in 96.6% (n = 56) of the cases. Recurrence was noted in 3.44% (n = 2) of the cases. A p value was 0.001, thus suggesting statistically highly significant result. On the basis of present study, though we can conclude that the MA with the intact inferior and the lingual cortex can be managed effectively with conservative treatment with long term regular follow up, still we would caution that the reader must use their best clinical judgement based on latest available data. For some patients, returning to clinic frequently and undergoing multiple minor procedures may not be suitable to be considered the best, whereas resection and reconstruction may be deemed more appropriate.

Straight lift technique as an alternative to surgical extraction of an intact, partially impacted mesioangular mandibular third molar.

Impacted mandibular third molar removal is the most common procedure performed by oral and maxillofacial surgeons. An array of alternative procedures have been suggested, like operculectomy in cases of pericoronitis and coronectomy in certain cases. However, these procedures pose several disadvantages, and we propose a relatively non-invasive 'straight lift technique'. This technique is specifically useful in straightening abnormally positioned mesioangular third molars as a substitute of complete removal. This can improve tooth function, eliminate the need for surgical intervention, and reduce the risk of complications associated with third molar removal.

Modified Temporalis Myofascial Flap for Management of Temporomandibular Joint Ankylosis: JAIN Technique.

Background: One of the management modalities of temporomandibular joint ankylosis is interpositional gap arthroplasty. The most commonly used interpositioning material is temporalis myofascial flap owing to its close proximity to operating site. However, sometimes this flap becomes insufficient in terms of length. Hence, we propose a technique of temporalis myofascial flap lengthening. Technique: The technique described in the manuscript increases the length of the flap by 1½-fold. This increases the reach of the flap till the medial aspect of the created gap avoiding bone-to-bone contact during movement of the jaw. Conclusion: This technique can be easily and effectively used to ensure proper interpositioning during management of temporomandibular joint ankylosis to avoid recurrence.

Histopathologic spectrum and clinical correlation of lesions of jaw - a series of 60 cases.

Odontogenic tumors have the potential for the development of malformations of the teeth as well as the surrounding tissue. Sound knowledge of various types of jaw lesions and their characteristics will help the clinician with timely measures and management. Our main aim was to study the histopathological nature of various jaw lesions retrieved from biopsies and resected specimens. Consecutive 60 cases of jaw lesions were analyzed. Odontogenic cyst, odontogenic tumor, fibro-osseous lesions, and giant cell lesions were included in this study. Lesions of the oral cavity, soft tissue lesions, secondary and inflammatory lesions of the jaw were excluded. H&E stained slides were examined by light microscopy. A total of 60 jaw lesions were analyzed for histologic type. Odontogenic cysts (55%) were found to be most common followed by odontogenic tumors (25%), fibro-osseous lesions (10%), giant cell lesions (05%), and non-odontogenic cysts (05%). The most commonly affected age groups were between 20-40 years. The mandible was more commonly involved bone. To conclude, based only on histology, the distinction between odontogenic cysts is difficult and almost impossible when they are secondarily infected. For definitive diagnosis clinical-radiological correlation is needed.

Is the Use of Intermaxillary Fixation Screws an Alternative to Erich Arch Bars for Maxillomandibular Fixation During Management of Maxillofacial Fractures? A Systematic Review and Meta-Analysis.

STUDY DESIGN: Systematic review and meta-analysis. OBJECTIVE: Maxillomandibular fixation (MMF) is a step of paramount importance during the management of maxillofacial trauma. Erich arch bars are being used for this purpose for decades but with advances in maxillofacial trauma management, intermaxillary fixation screws came into existence and are being used routinely. The present study was designed to identify if the intermaxillary fixation screws are really an alternative to Erich arch bars for management of maxillofacial trauma. METHODOLOGY: An exhaustive literature search was conducted in May 2020 on various electronic databases and studies comparing Erich arch bars and intermaxillary fixation screws were recruited for the analysis. Random-effects model with Mantel Haenszel statistics was used to analyze oral hygiene and duration of achieving MMF. RESULTS: A total of 96 studies were identified, out of which 8 studies were included in the meta-analysis. There was no statistically significant difference in oral hygiene status of the patients in both the groups. Intermaxillary fixations screws required statistically significantly less time in achieving MMF. Needle stick injury was prominently seen with the use of Erich arch bar whereas other complications like mucosal coverage, root injury, screw loosening and screw fracture makes the use of intermaxillary fixation screws questionable. CONCLUSION: The present meta-analysis suggests that there is not enough evidence to recommend the use of intermaxillary fixation screws as an alternative to Erich arch bars. Further research with large sample size, high quality evidence and better methodology is recommended in this direction.

Meta-Analysis to Evaluate the Efficacy of Sternocleidomastoid Muscle Flap as a Reconstruction Modality in Prevention of Frey's Syndrome Following Parotidectomy.

BACKGROUND: One of the commonest complications following parotidectomy is Frey's syndrome (FS). The use of sternocleidomastoid muscle (SCM) flap to prevent FS is controversial. Hence, this study has been designed to compare the effect of SCM flap with no reconstruction in prevention of FS following parotidectomy. METHODOLOGY: An exhaustive literature search was conducted in July 2019. Studies focusing on sternocleidomastoid flap following parotidectomy were included in the meta-analysis. A random effects model was used to generate pooled estimates. Odds ratio with a 95% confidence interval was calculated for subjective symptoms and objective test. RESULTS: A total of 125 studies were identified, out of which 17 studies were recruited in the meta-analysis. Sixteen studies were analyzed for the subjective symptoms, and ten were analyzed for the objective signs. There was no statistically significant difference in the occurrence of FS with the use of SCM flap on objective analysis. However, the subjective analysis showed a statistically significant reduction in FS following reconstruction with SCM flap after parotidectomy. CONCLUSION: The present meta-analysis suggests that the use of SCM flap following parotidectomy has no effect in reducing the incidence of Frey's syndrome.

Oral submucous fibrosis in children: an alarming condition and challenges in management.

Oral submucous fibrosis (OSF) is a well-documented potentially malignant condition. It affects most commonly the adult patients of India and Indian subcontinent, only few cases affecting children have been reported in the literature. This paper presents three cases of OSF below the age of 12 years and reviews the aetiology, clinical presentation, treatment modalities in children with improved follow-up results. Clinical features like restricted mouth opening, burning sensation and history of betel nut chewing helps in the diagnosis of the patients, which can be confirmed by histopathological examination. Conservative management and oral physiotherapy in children help in improved mouth opening. Counselling the children, their friends and parents also plays a vital role. The present paper highlights that children on a larger scale are using tobacco products and further studies are required with larger sample size.

Two miniplates versus 3-dimensional plate in the management of mandibular subcondylar fractures: a retrospective analysis.

PURPOSE: The aim of the present study was to evaluate the outcomes in patients with subcondylar fracture of mandible treated with 2 single miniplates compared to a 3-dimensional (3D) plate. PATIENTS AND METHODS: This is a retrospective study which included patients diagnosed and treated for mandibular subcondylar fracture from January 2015 to December 2019. Included patients were divided into two groups, group 1: 2 miniplate group and group 2: 3D plate group. The data was obtained from the patients' records and evaluated for various outcomes including occlusal stability, postoperative complications like plate fracture, non-union, plate or screw loosening, and plate or screw infection leading to implant removal, wound dehiscence, salivary fistula, and facial nerve paralysis. The statistical analysis was performed using chi square test and Student's t test. RESULTS: A total 58 patients (43 males and 15 females) were enrolled in the two groups ranging from 21 to 59 years. A total of 35 patients were recruited in group 1, whereas 23 patients were recruited in group 2. There was no statistically significant difference in the two groups with regard to the age range, gender, diagnosis, side of fracture, and accompanying fractures. Occlusal instability, wound dehiscence, and facial nerve paralysis was found in both the groups. Group 1 had 1 patient which required implant removal due to screw loosing, whereas group 2 had 2 patients which required plate removal due to plate fracture. One patient in group 2 required second surgery for fixation of fracture due to non-union. One patient in group 1 developed a sialocele postoperatively. However, there was no statistically significant difference in any of the variables assessed among the two groups (p > 0.05). CONCLUSION: The results of our study indicate that the 2 miniplates and 3D plate system are effective in the management of mandibular subcondylar fractures.

Reconstruction using sternocleidomastoid muscle flap versus posterior belly of digastric muscle flap compared with no reconstruction following superficial parotidectomy.

INTRODUCTION: The most common complications following superficial parotidectomy are formation of contour deformity and development of Frey's syndrome. Multiple modalities are being used to prevent these complications. We hereby intend to compare the reconstruction modalities (sternocleidomastoid (SCM) muscle flap, posterior belly of digastric (PBD) muscle flap) with) No reconstruction (NR) following superficial parotidectomy. MATERIALS AND METHODS: A comparative study was designed which included 15 patients requiring parotidectomy. These patients were divided into three groups viz. SCM, PBD, and NR. The functional outcome (facial nerve involvement, Frey syndrome, ear lobule sensation, neck movements) and the esthetic results were evaluated subjectively and objectively. The outcomes were statistically evaluated using chi-square test and ANOVA test. RESULTS: Facial nerve palsy occurred in 2 cases in each group, and all of them recovered completely within 6 months. The Minor starch iodine test was positive in 1 patient in the SCM group, in 2 patients in the PBD group, and in 4 patients in the NR group; only 1 patient of PBD group and 3 patients of NR group complained of gustatory sweating. Neck movements were unaffected in the PBD and NR groups; however, 1 patient complained of mild discomfort and pain during neck movements in the SCM group. CONCLUSION: Primary closure showed the worst results regarding cosmetic deformity. Hence, it is recommended to mandatorily reconstruct the defect. However, the sternocleidomastoid muscle flap is a better cosmetic option compared with posterior belly of digastric muscle flap. In cases with larger defects, a combination of both the flaps can be used. SCM flap also lowers the incidence of Frey syndrome objectively and subjectively with no reported hazard of the spinal accessory nerve and mildly affected neck movements.

Horizontal fracture of anterior mandible.

A 33-year-old male patient reported to us with the history of assault. The patient was cooperative and oriented, with no sign of head injury. He was assaulted with an axe over the mandible. The patient is having posteroanterior view radiographs of the mandible suggesting isolated horizontal fracture of the anterior mandible. Under general anaesthesia, this unusual fracture was treated by open reduction and internal fixation with a three-dimensional plate and miniplates. The case was managed successfully without any postoperative complications.

Hemangiopericytoma of meningo-fronto-naso-orbito-maxillary complex.

Hemangiopericytoma (HPC) is a rare vascular tumour and difficult to diagnose clinically. Incidence is reported in fourth to fifth decade of life.With female predominance, 3%-5% cases affect the oral cavity, sinus lining and meninges. The patient presented with 8×6 cm swelling on her face, evaluation reported it to be HPC. Bilateral maxillary artery embolisation, wide local excision of the lesion, preserving the left eye and its function, was done. No recurrence is reported at 1-year follow-up. Response of such lesions to radiotherapy is questionable; with no lymphadenopathy and adequate encapsulation, embolisation of feeder vessel followed by a wide local excision of the lesion seems to be a fairly good option of treatment.

Osteomyelitis of frontal sinus, zygomatic bone and maxilla.

A 52-year male patient reported with loosening of right upper jaw. He has no pain or discharge, or any acute symptoms and systemic disease. Intraoral examination reveals necrosed maxillary bone. He also has no sickle cell disease, hepatitis, HIV or tuberculosis. 3D CT scan reveals destruction of maxilla, maxillary sinus, lateral nasal wall, superior and inferior orbital wall, zygoma and frontal bone(outer table). The clinical diagnosis of osteomyelitis was made. Under general anaesthesia, sequestrectomy was done with the help of Weber-Ferguson incision with infraorbital extension for maxilla, maxillary sinus, zygomatic bone, lateral nasal wall and infraorbital and medial wall of orbit. Frontal sinus region sequestrectomy was done via bicoronal flap. The patient was completely diseased free after 4 years follow-up.

Non-syndromal multiple supernumerary and permanent impacted teeth in mother and her one child.

Multiple permanent impacted supernumerary teeth are rare and are most of the times associated with syndromes. The prevalence for non-syndromic multiple supernumerary teeth is less than 1%. We herein presenting a case of non-syndromic multiple supernumerary impacted teeth in a female patient and her child. The patient has three children; out of them, two had normal dentition and the youngest child had 60 teeth (35 impacted supernumerary with 25 erupted teeth). The patient herself had a total of 54 teeth. Their medical history was not significant. The systemic investigations were not suggestive of any syndrome and disease. Very few cases reported more than 30 supernumerary and impacted teeth bilaterally in both the jaws. This case report becomes unique as both mother and her child presented with more than 30 supernumerary impacted teeth.

Efficacy of preoperative antibiotics in prevention of dental implant failure: a Meta-analysis of randomized controlled trials.

BACKGROUND: Dental implants are commonly used for replacement of missing teeth. Despite the published data highlighting the high success rate of dental implants, failures do occur. Some of these failures are believed to be a result of bacterial contamination at the site of implant insertion. Various antibiotic regimens have already been suggested to prevent failure due to infection. OBJECTIVE: This meta-analysis aims to examine the efficacy of preoperative antibiotics in prevention of dental implant failure secondary to infections. METHODOLOGY: An exhaustive search was conducted on electronic database including PubMed Medline, Google Scholar, Scopus, and Cochrane on July 15, 2019. All the randomized controlled trials (RCT) comparing preoperative antibiotics with no antibiotics/placebo in dental implants were included in the study. The primary outcome for assessment was implant failure. A random effect meta-analysis was conducted for risk ratios of dichotomous data. RESULTS: A total 8544 abstracts were screened following which 16 full text articles were reviewed and 5 RCTs were included in the analysis. Meta-analysis results indicated that the preoperative antibiotics resulted in statistically significantly lower number of implant failures. CONCLUSION: Preoperative antibiotics effectively reduce the implant failure rate. However, it is recommended to conduct large-scale RCT to determine the efficacy of preoperative antibiotics in dental implants.
