Frequency of tori in patients seen at prosthodontics department of Islamabad dental hospital

Tori are benign growths of new bone in the mouth. The bony prominences go unobserved for a long period of time in the oral cavity due to their painless and benign nature. These are usually noticed during fabrication of a prosthesis as they affect the management of partially and completely edentulous patients. The occurrence of tori vary in populations and between genders. The aim of this study was to assess the frequency of torus palatinus and torus mandibularis seen in patients who visited Prosthodontics department of Islamabad Dental Hospital and to find out their gender predominance and variations among the sizes. A total of 278 patients over a period of 4 months were assessed. The results showed that maxillary tori were present in 7.6% of patients and mandibular tori were present in 0.3%. Among these 59% were females and 41% were males. The most frequent age group for tori was of 46-50 years

Prevalence of causative factors for musculoskeletal disorders and their awareness amongst dental surgeons

Musculoskeletal disorders [MSD] are a significant occupational health problem in dentists the causes of which are complex and diverse. The aim of this study was to find the level of awareness and prevalence of causative factors of MSD's amongst Dental Surgeons. A cross-sectional survey on 140 dentists of the University College Of Dentistry was conducted from November 2013-January 2014. A 10 item questionnaire was used. Data was analyzed using SPSS version 20, chi square test was applied with a cut-off value of 0.05. Out of 140 subjects 67.1% were familiar with MSD. A total of 99[70.7%] reported pain, [46.4% mild pain, 48.6% moderate pain, 5.1% severe pain]. Most common site of pain reported was back/ waist [64.5%] followed by neck/shoulder 33.3%. A strong correlation was found between ill-posture and pain [p-value 0.004]. it is recommended that ergonomic strategies should be used for preventing MSD

Aglossia: a rare case report and review

Aglossia is a rare malformation resulting in the partial development or complete absence of the tongue. It is commonly associated with craniofacial and limb defects [Oromandibular Limb Hypogenesis Syndrome].The etiology is unknown and various theories have been proposed for this. The objective of presenting the case report and literature review is to discuss the clinical presentation, causative factors and possible management strategies of this rare malformation

Craniofacial measurements for the determination of occlusal vertical dimension and gender dimorphism in a section of Pakistani population

The objective of this study was to check the authenticity of various facial measurement theories, their implementation among Pakistani population and comparison of these measurements in male and female. Prospective Comparative The study was conducted in Department of Prosthodontics, College of Medicine and Dentistry, The University of Lahore, Pakistan from March 2014 to September 2014. Thirteen different measurements were taken on fully dentate subjects. All measurements were taken on fully dentate subjects in centric occlusion. The craniofacial distances were measured using Boley's guage of [Tricle] brand while the distance from chelion to chelion along the curvature of the lips was measured using a flexible scale. Results were statistically analyzed by using SPSS version 20. Ten measurements showed significant gender dimorphism [p <0.05]. However, there were three measurements, hair line to right eyebrow line, center of pupil of right eye to center of pupil of left eye and outer canthus of right eye to inner canthus of right eye multiplied by two, which revealed close approximation in male and female [p > 0.05]. There is no significant gender difference in these three measurements for the determination of OVD among Pakistani subjects

Complications associated with tooth supported fixed dental prosthesis amongst patients visiting University College of Dentistry Lahore

The aim of this cross-sectional study was to assess the complications associated with tooth supported fixed dental prosthesis amongst patients reporting at University College of Dentistry Lahore, Pakistan. An interview based questionnaire was used on 112 patients followed by clinical oral examination by two calibrated dentists. Approximately 95% participants were using porcelain fused to metal prosthesis with 60% of prosthesis being used in posterior segments of mouth. Complications like dental caries, coronal abutment fracture, radicular abutment fracture, occlusal interferences, root canal failures and decementations were more significantly associated with crowns than bridges [p=0.000]. On the other hand esthetic issues, periapical lesions, periodontal problems, porcelain fractures and metal damage were more commonly associated with bridges [p=0.000]. All cases of dental caries reported were associated with acrylic crown and bridges, whereas all coronal abutment fractures were associated with metal prosthesis [p=0.000]. A significantly higher number of participants who got their fixed dental prosthesis from other sources i.e. Paramedics, technicians, dental assistants or unqualified dentists had periapical lesions, decementations, esthetic issues and periodontal diseases. This association was found to be statistically significant [p=0.000]. Complications associated with fixed dental prosthesis like root canal failures, decementations, periapical lesions and periodontal disease were more significantly associated with prosthesis fabricated by other sources over the period of 5 to 10 years

Mandibular arch form analyses: a comparison between results of two different methods

This study was conducted to determine the morphology ofmandibular dental arch forms. Two different methods were used for this purpose and compared to find out the frequency distribution. It was conducted on 100patients visiting Lahore Medical and Dental College, Lahore. Dental casts were photocopied and investigated to find out the square, tapering and ovoid arch forms. A mathematical model of arch form determination advocated by Noroozi and superimposition oforthoform templates were the two methods used. A comparison of frequency distribution for the results of two methods was carried out by applying [Chi square] test. Cross tabulation was done to study the congruence of the two methods on various arch forms. Frequency distribution of ovoid, square and tapering arch forms was 74%, 14%and 12% respectively by Noroozi's mathematical model and 56%, 7% and 37% respectively by the orthoform templates.There was a noteworthy difference in frequency distribution of arch forms according to the two methods. The p-value [p <0.001] was statistically significant. However both methods showed ovoid arch form as the most prevalent in the sample

Arch form analyses: a comparison of two different methods

This study determines and compares the frequency distribution and results of two methods establishing morphology of the dental arch form. It was conducted on 250 patients visiting Lahore Medical and Dental College, Lahore. The casts were measured and photocopied, which were analyzed first by using a mathematical model as advocated by Noroozi3 and then by superimposing orthoform templates to determine the arch forms. The dental arches were classified into square, ovoid, and tapered forms to determine and compare the frequency distributions between the two methods. The comparison between results of both methods was made by applying chi square test. Cross tabulation was done to observe the congruence of two methods on different arch forms. According to Noroozi's mathematical model, frequency distribution of ovoid, square and tapering arch forms was found to be 82%, 64%and 11.2% respectively while according to orthoform templates those were 53.2%, 9.2% and 37.6% respectively. There was a statistically significant difference between results of two methods [P<.001]. The ovoid arch form was most common arch form according to both methods. There was a statistically significant difference in the results of two methods as well as their frequency distribution

Papillo-incisal distance incisive papilla maxillary incisor distance in subjects of various arch forms
