Platelet-Rich Fibrin-Enhanced Bone Healing Co-grafted With Either Hydroxyapatite and Beta Tricalcium Phosphate or Demineralized Freeze-Dried Bone in Small Maxillofacial Osseous Defects: A Clinical Comparison.

INTRODUCTION: This study was conducted to clinically compare a commercially available combination of 70:30 nanocrystalline hydroxyapatite (HA) and beta tricalcium phosphate (ßTCP) along with platelet-rich fibrin (PRF) with demineralized freeze-dried bone (DFDB) grafts along with PRF in small maxillofacial osseous defects. MATERIALS AND METHODS: Thirty patients with one osseous defect were randomly distributed into two groups of 15 each: Group A and Group B. Group A patients received HA+ßTCP+PRF while Group B received DFDB + PRF. Postoperative pain, swelling, wound dehiscence, and the presence or absence of infection were evaluated at various intervals up to seven postop days and compared between the two groups and within either group. A technetium 99m methylene diphosphonate (MDP 99mTc) scan was also done for a representative patient of either group at the end of three months to evaluate the fate of the graft. RESULTS: We found no significant difference between the two groups for any of our parameters. Significant improvements were noted for pain and swelling within either group at various intervals. The MDP 99mTc scan showed increased tracer uptake for the representing patient of either group. CONCLUSIONS: HA+ßTCP is more inexpensive than DFDB and more readily available and has no host incompatibility or infection potential, resulting in similar clinical postoperative states as DFDB when either is used with PRF.

Bilateral sagittal split osteotomy a versatile approach for correction of facial deformity: A review literature.

Poor facial cosmesis resultant from dysgnathias usually accounts for a range of these individuals' psychological and social problems. Disturbances of both esthetics and function are caused by jaw deformity and associated structures' deformity such as malocclusion. The correction of these deformities is one of the most challenging and intriguing aspects of maxillofacial surgery. Despite having become routine only relatively recently, rigid internal fixation has advanced rapidly, its results are consistent and predictable and thus, its knowledge applies in orthognathic surgery besides other areas of maxillofacial surgery. The bilateral sagittal split osteotomy (BSSO) is a common orthognathic procedure performed on the mandible. First described by Trauner and Obwegeser in 1957, modified by Dal Pont and refined by Epker, several modifications of the BSSO have been introduced aiming to enhance surgical convenience, minimize morbidity, and maximize stability. The aim of this article is to review the literature of this technique from the historical perspective and to present a standard operation technique.

Antifungal efficacy of herbs.

Candida carriage was reported to be common in oral cancer patients, with C. albicans being the predominant species. The prevalence of diseases caused by Candida species have been found to increase in recent years. AIM: The aim of our study was to find the antifungal activities at MIC of selected fifteen plant leaves extracts prepared in three different solutions (methanol and ethanol) against the opportunistic pathogen Candida albicans isolated from oral cavity infections. It may also help the clinician to treat the patient not only for the particular lesion that is present, but also to treat the infection by Candida albicans so as to reduce its potential to malignant transformation. Material n methods: Leaves extract of selected plant prepared in methanolic and eethanolic solution have been chosen for the investigation of in vitro antifungal activity which acts as expectorant and not having toxic properties on humans while for comparison or control, antifungal drugs have been taken. Results showed that Candida albicans shows most sensitivity towards the standard antibiotic cotrimoazol but very less towards other drugs like Fluconazole, minocycline, erythromycin respectively which indicated Candida albicans shows some resistance character towards drugs while the herbal extracts of Lawsonia inermis, Withania somnifer, Curcuma longa, Cymbopogon citrates and Zingiber officinale gives the best inhibitory effect and they have the potential to control growth of Candida albicans.

An epidemiological study on pattern and incidence of mandibular fractures.

Mandible is the second most common facial fracture. There has been a significant increase in the number of cases in recent years with the advent of fast moving automobiles. Mandibular fractures constitute a substantial proportion of maxillofacial trauma cases in Lucknow. This study was undertaken to study mandibular fractures clinicoradiologically with an aim to calculate incidence and study pattern and the commonest site of fractures in population in and around Lucknow. Patient presenting with history of trauma at various centers of maxillofacial surgery in and around Lucknow were included in this study. Detailed case history was recorded followed by thorough clinical examination, and radiological interpretation was done for establishing the diagnosis and the data obtained was analyzed statistically. Out of 66 patients with mandibular fractures, highest percentage was found in 21-30 years of age with male predominance. Road traffic accidents were the most common cause of fracture with parasymphysis being commonest site. Commonest combination was parasymphysis with subcondyle. There was no gender bias in etiology with number of fracture sites. The incidence and causes of mandibular fracture reflect trauma patterns within the community and can provide a guide to the design of programs geared toward prevention and treatment.

Efficacy of plain radiographs, CT scan, MRI and ultra sonography in temporomandibular joint disorders.

The complexity of structure and functions of the Temporomandibular Joint (TMJ) make the diagnosis of its diseases/disorders difficult. Remarkable progress made in the field of imaging of this joint led us to compare four imaging modalities viz. plain radiographs, CT scan, MRI and ultrasound. We found that MRI was most specific and sensitive for interpretation of soft tissue and inflammatory conditions in the joint, whereas CT examination produced excellent image for osseous morphology and pathology. Plain X-rays are useful for destructive bony changes and sonography is a good in aid in diagnosing disc derangement and is very economical.

Two wound-covering materials in the surgical treatment of oral submucous fibrosis: a clinical comparison.

INTRODUCTION: Oral submucous fibrosis (OSMF), a chronic debilitating condition of the mouth, has been treated both surgically and non-surgically, but non-surgical methods yield inconsistent results. The surgical methods essentially comprise of bilateral sectioning of fibrous bands with or without coronoidectomy followed by covering of the surgical defect with a graft or a wound dressing material such as collagen sheet. MATERIALS AND METHODS: This study comprised 30 clinically diagnosed cases of OSMF. This study compared transposition of buccal pad fat graft with collagen sheet to cover the defect within the following parameters: pain, swelling, mouth opening, color of mucosa, palpability of fibrous bands, and suppleness of mucosa. RESULTS: We found significant difference in the postoperative mouth opening, an insignificant difference for post surgical morbidity and higher grades of surgical convenience in using collagen sheet as a wound dressing material. CONCLUSION: Collagen membrane is a superior method compared to transposition of the buccal pad of fat as a graft to cover the surgical wound in the treatment of OSMF of grade III and above.
