OCLC Number/Unique Identifier: 8235041431
Background: The present study was conducted to assess effect of cigarette smoking on different denture base material.
Materials & Methods: The present study was conducted in the department of Prosthodontics. A total of sixty wax specimens in the shape of circular discs were prepared. These were divided into two groups. Group I (30) specimens were heat‑cured denture base materials and group II (30) specimens were flexible denture base materials. Both specimens were further divided into four subgroups of 15 each. Subgroup I was heat‑cured denture base material specimens (control group), subgroup II was flexible denture base material specimens (control group), subgroup III was heat‑cured denture base material specimens exposed to cigarette smoking (study group) and subgroup IV was flexible denture base material specimens exposed to cigarette smoking (study group). The initial (IRa) and final (FRa) surface roughness was measured before and after smoking test of the specimens.
Results: It was observed that in group I, mean IR (µm) value was 0.182 and FR value was 0.572. In group II, mean IR (µm) value was 0.265 and FR value was 0.831. In group III, mean IR (µm) value was 0.195 and FR value was 1.892. In group IV, mean IR (µm) value was 0.291 and FR value was 1.892. The difference was significant (P< 0.05).
Conclusion: The surface roughness of the specimens fabricated from the flexible denture base material was found to be more compared to heat‑cured denture base specimens after exposure to cigarette smoke. There is need to educate the patients regarding cleanliness of denture to avoid infection in the oral cavity.
Correlation between mandibular condylar position and clinical dysfunction index after bilateral sagittal split osteotomies
Published on: 4th June, 2019
OCLC Number/Unique Identifier: 8165128692
Several articles have discussed mandibular condyle position after bilateral sagittal split osteotomies (BSSO). However, previous studies have sought to establish a relationship between orthognathic surgery and the improvement of temporomandibular joint (TMJ) signs and symptoms. Also, they have been limited to two-dimensional evaluation of condylar position considering only the condylar “sag” or improper inferior seating of the condyle. The purpose of this study was to investigate a relationship between changes in condylar position using three-dimensional computed tomography and the negative clinical impact of BSSO on the temporomandibular joint.

In our past 200 years we have seen the advancing development of Dental Arts and Science though discoveries by its practitioners. Perhaps it will do some good to review the basis upon which fixed tooth replacement has evolved—that is the prosthetic crown.
Pathological Findings on Dental Panoramic Tomograms of Edentulous Patients Seen at a University Hospital
Published on: 19th April, 2018
OCLC Number/Unique Identifier: 7666273509
Objective: To describe pathological fi ndings on pre-treatment dental panoramic tomograms of edentulous jaws taken before complete denture treatment.
Design: Descriptive cross-sectional study.
Setting: Prosthetic division, Department of Conservative and Prosthetic Dentistry.
School of Dental Sciences, University of Nairobi.
Results: Data was obtained from clinical records and OPGs of 163 edentulous patients seen at the prosthetic clinic between 2010 and 2016 for complete denture therapy. From history and examination alone, clinicians reported significant findings on 50.3% of records, while 43.6% had no such findings. Ten (10) (6.1%) records were unclear. Examination of OPGs revealed 79.1% of the films had no pathological findings while in 20.9% had. Most of the findings (70.0%) were retained roots, 6% were radio-lucencies, 12% were other radio-opacities, 9% were impacted teeth while 3% had both retained root and radio-opacity. Most pathologies (64%) were located in the posterior region of jaws while the other findings were evenly distributed in the anterior and posterior regions of the jaws. There was no predilection of pathological findings to any other factor other than gender. In 83.4% records, queries on clinical notes coincided with significant findings on OPGs; while 16.6% were either unclear or did not coincide. Most (71%) OPG findings led to modification of treatment plan.
Conclusion: Pathological findings are common on pre-treatment OPGs. It may be good practice to take an OPG for edentulous patients prior to complete denture therapy where such services are available, to prevent complications from intra-bony pathologies. However, Most of the findings are either detectable by clinical exam or may not be of major consequence to the health of patients. Complete denture may be done without OPGs for new and old denture wearers where the service is not available.
Large perforating Submandibular Stone-A Case Report

Salivary stone (sialothiasis) is a calcifying concentration within the ductal system of salivary gland [1]. The majority of salivary calculi occur in the submandibular gland duct because of its length, upward course and the thicker mucus [2].
Open bite malocclusion: An overview
Published on: 12th January, 2018
OCLC Number/Unique Identifier: 7379416963
The term open bite is referred as no contact between anterior or posterior teeth. The complexity of open bite is attributed to a combination of skeletal, dental and habitual factors. Etiology of open bite can be attributed to genetics, anatomic and environmental factors. However, the tendency toward relapse after conventional or surgical orthodontic treatment has been indicated. Therefore, open bite is considered one of the most challenging dentofacial deformities to treat. The aim of this article is to emphasize that early etiological diagnosis, dentofacial morphology and classification are essential to the successful outcome of the technical intervention. Failure of tongue posture adaptation subsequent to orthodontic and/or surgical treatment might be the primary reason for relapse of open bite. Prolonged retention with fixed or removable retainers is advisable and necessary in most cases of open bite treatment. The treatment of open bite remains a tough challenge to the clinician; careful diagnosis and timely intervention with proper treatment modalities and appliance selection will improve the treatment outcomes and long-term stability.
Fixed functional Appliances in Orthodontics-A review

OCLC Number/Unique Identifier: 7379415494
Correcting class II malocclusion has always challenged an orthodontist owing to the complex and multifactorial aetiology. Age of patient and selection of the appliance plays an important role in the outcome of the treatment. Growth modification using functional appliances achieves stable results in class II patients. An orthodontist has wide variety of fixed and removable appliances for addressing a class II malocclusion. In this review article an attempt has been made to compile various available fixed functional appliances.
Clinical Case: Necrotizing Fasciitis of the neck after surgery of a Mandibular Radicular Cyst
Published on: 24th November, 2017
OCLC Number/Unique Identifier: 7379455745
Necrotizing fasciitis is a quickly progressing soft tissue infection that can be described with diffuse necrosis of subcutaneous tissue and superficial fascia. The cause of this can be infectious process of odontogenic origin, most commonly caused by mixed gram+ and gram- , aerobic and anaerobic microorganisms that are found in patients that are predisposed to infections. In a case of undiagnosed illness, there is a possibility of life threatening complications. This case analysis introduces the diagnostic criteria of the disease and treatment plan, encouraging doctors to devote more attention to prevention of infections.

Aim: To assess and learn oral health awareness and hygiene practices among geriatric patients and also to identify important barriers in the establishment of oral health services, disease prevention and oral health promotion programmes for the same.
Materials and Methods: A total of 500 patients in the age group of 50 years and above were selected using random sampling technique. A self‑administered structured questionnaire including 20 multiple choice questions was given to them. The results were analyzed using percentage.
Results: The result of this study shows an acute lack of oral hygiene awareness and limited knowledge of oral hygiene practices. In Rohini, few people use tooth brush.
Conclusions: Hence, there is an urgent need for comprehensive educational programs to promote good oral health and impart education about correct oral hygiene practices.
Corticotomy facilitated correction of skeletal class II malocclusion
Published on: 26th October, 2017
OCLC Number/Unique Identifier: 7379412270
Selective alveolar decortication and periodontal augmentation with a bone graft were the two procedures used for the correction of the skeletal class II malocclusion in the case reported. A 25-year-old male patient presented with a skeletal class II malocclusion with increased bi-maxillary dento-alveolar protrusion, increased overjet, deep bite and imbricated and rotated mandibular incisors with bilateral presence of supernumerary teeth in the maxillary right and left premolar regions. Extraction of supernumerary in the maxillary right and left premolar region, and impacted UL5 was done. Pre-adjusted edgewise appliance, Roth’s prescription (0.022x0.028-inch slot), was bonded and a week later full thickness labial and lingual flaps were reflected in the maxillary and mandibular arches. Circumscribed corticotomy cuts was done and subsequently augmented with a bone graft. Orthodontic treatment was commenced immediately after surgery and orthodontic adjustments were performed every 2 weeks. The entire orthodontic treatment was completed in 9 months. Regional acceleratory phenomenon, triggered by the alveolar decortication, was responsible for the rapid correction of the malocclusion and the augmentation with the bone graft provided adequate bone volume for housing the teeth, thereby decreasing the possibility of subsequent relapse.
