Assessment of Pathway and Location of Posterior Superior Alveolar Artery: A Cone-Beam Computed Tomography Study.

Objective The current study evaluated the complicated pathway of the posterior superior alveolar artery (PSAA) and measured the prevalence, diameter, and length of PSAA to the alveolar crests of molars using cone-beam computed tomography (CBCT). The study compared findings between dentate and edentulous patients grouped by their age. In addition, the study researched the presence of the septa. Methods One hundred and fifty CBCT scans of patients with ages ranging from 20 to 80 years were analyzed for the study. The measurements of PSAA were obtained from CBCT scans. Results The PSAA was detected on CBCT scans of 87.3% of participants. The majority course of PSAA was intraosseous (right side 53.3%, left side 63.3%). The diameter of PSAA was 1.30±0.42 mm on the right side and 1.19±0.40 mm on the left side. The length of PSAA to the alveolar crest of the third molar (A1) was 17.16±2.72 mm on the right side and 17.82±3.2 mm on the left side, to the first molar (M1) was 11.6±2.66 mm on the right side and 11.65±2.37 mm on the left side, and to second molar (M2) was 12.51±1.96 mm on the right side and 12.44±2.72 mm on the left side. There was no significant difference noticed between dentate and edentulous participant groups. Six percent (6%) of the scans showed the septa in the maxillary sinus. Conclusions The study showed that CBCT scans and their analysis help the clinician to make a better radiographic diagnosis and clinical application while using surgical procedures, such as implant placement and sinus lift.

Use of Frontal Sinus and Nasal Septum Pattern as an Aid in Personal Identification and Determination of Gender: A Radiographic Study.

INTRODUCTION: Personal identification and gender determination of unknown person has a vital importance in forensic investigation. Human skull radiography is a useful tool in human identification in natural disaster, in any accidents such as fire accident and road traffic accident where body remains become degraded or severely destroyed. AIM: Present study was performed to evaluate the measurement of frontal sinus, uniqueness of various pattern of nasal septum when combined with frontal sinus observed on posterio anterior cephalogram for sex determination as well as personal identification. MATERIALS AND METHODS: A total of 80 individuals, 40 males and 40 females, between the age ranges of 18-30 years were selected. The selected individuals had their Posterio Anterior (PA) cephalogram performed after taking their informed consent. Right and left areas and the maximum height and width of the frontal sinus were determined and septum patterns were evaluated and both patterns were also combined and compared. The radiographs were taken on Xtropan 2000 OPG X-ray machine with cephalography attachment and KODAK CR 7400 digital radiography system. Mean and SD values of the greatest height and width of frontal sinus in male and female patients were thus evaluated. The mean values of the frontal sinus were greater in males and the left area was larger than the right area, based on student's t-test at the 5% level of significance. RESULTS: The combination of Frontal Sinus Patterns and Nasal Septum Patterns (FP+NSP) were assessed and found that there were nine classifiable patterns in 26 (32.5%) individuals (12 males and 14 females), each of which had common representations in more than one individual. Besides these patterns, there were unique unclassifiable patterns in 54 (67.5%) individuals. CONCLUSION: The present study supports the use of radiographic evaluation of frontal sinus dimensions, frontal sinus patterns, nasal septum deviations and the combination FP+NSP patterns for personal identification and gender determination in forensic investigations.

A case of unilateral atypical orofacial pain with Eagle's syndrome.

Eagle's syndrome is not an uncommon condition, but less known to physicians, where an elongated styloid process or calcified stylohyoid ligament compresses the adjacent anatomical structures leading to orofacial pain. Diagnosis is made with appropriate radiological examination. Nonsurgical treatment options include reassurance, analgesia, and anti.inflammatory medications; and the surgical option includes a transoral or external approach. Here, we present a case report of a male patient, of age38 years, with a chief complaint of unilateral atypical orofacial pain on the right side of his face radiating to the neck region, for the last two months.

Facial pain followed by unilateral facial nerve palsy: a case report with literature review.

Peripheral facial nerve palsy is the commonest cranial nerve motor neuropathy. The causes range from cerebrovascular accident to iatrogenic damage, but there are few reports of facial nerve paralysis attributable to odontogenic infections. In majority of the cases, recovery of facial muscle function begins within first three weeks after onset. This article reports a unique case of 32-year-old male patient who developed facial pain followed by unilateral facial nerve paralysis due to odontogenic infection. The treatment included extraction of the associated tooth followed by endodontic treatment of the neighboring tooth which resulted in recovery of facial nerve plasy. A thorough medical history and physical examination are the first steps in making any diagnosis. It is essential to rule out other causes of facial paralysis before making the definitive diagnosis, which implies the intervention. The authors hereby, report a case of 32-year-old male patient who developed unilateral facial nerve paralysis due to odontogenic infection with a good prognosis after appropriate treatment.

Efficacy of low-level laser therapy in treatment of recurrent aphthous ulcers - a sham controlled, split mouth follow up study.

INTRODUCTION: Apthous ulcers, commonly referred to as canker sores, are the most common ulcerative lesions of the oral mucosa. These are usually painful and are associated with redness, and occasional bleeding from the affected area(s). The aims of treatment are to reduce pain and healing time. AIMS: To assess clinically the efficacy of Low-level laser therapy (LLLT) on recurrent aphthous ulcers for reduction of pain, lesion size, and healing time and to compare the results with those of a sham control group. SETTINGS AND DESIGN: A total of 30 patients who presented with two separate aphthous ulcers were included in the study. Each lesion was randomly allotted to either the active treatment group or the sham control group. MATERIALS AND METHODS: Lesions which were included in the active group were treated with LLLT in a single sitting, which was divided into four sessions. Lesions in the sham control group were subjected to similar treatment without activating the LASER unit. Each patient was evaluated for pain, lesion size, and complete healing at the following intervals; immediately post LLLT and one day, two days, and three days follow up. Statistical Analysis : The Student's t-test was used for statistical evaluation of the data. RESULTS: Complete resolution of the ulcers in the active group was 3.05 ± 1.10 days as compared to 8.90 ± 2.45 days in the sham control group. Immediately, post the LLLT application, complete pain relief was observed in 28 of the 30 patients of the active group. CONCLUSION: LLLT was effective in relieving pain and reducing the healing time during the treatment of aphthous ulcers.
