Periodontal health and oral hygiene practice of elderly Saudis living at Riyadh Nursing Home

Aljoharah A. Al-Sinaidi — 2011-11-28

Abstract: Eighty-three Saudi elderly subjects (51 men and 32 women) living at Riyadh Nursing Home were interviewed regarding their oral hygiene practices, and were examined to assess their periodontal health status using the Community Periodontal Index of Treatment Needs (CPITN). Results showed that oral hygiene was practiced by 65% of the subjects and was performed more frequently by women. Less than 10% of the subjects had visited a dentist in the last three months, and only 24% perceived a need for periodontal treatment. Only 8.4% of the subjects had healthy periodontium. Calculus was the most prevalent finding among the subjects (48.2%), and was significantly more prevalent in men. Bleeding on probing and periodontal pockets was recorded in 24.1% and 19.3% of the subjects, respectively, with no statistically significant difference between men and women. In conclusion, the periodontal health status of elderly Saudi living at Riyadh Nursing Home is poor and their oral hygiene practices are inadequate. This category of the elderly needs a periodontal health promotion program in order to provide oral health necessary to improve their quality of life.

Evaluation of two compact electronic apex locators in the presence of different endodontic solutions

Solaiman Mohammed Al-Hadlaq — 2011-12-02

Abstract: The purpose of this study was to evaluate the accuracy of two compact electronic apex locators, the Root ZX mini and the Mini Apex Locator, in the presence of different endodontic solutions and to compare their performance to the Root ZX electronic apex locator. The sample consisted of 60 extracted single-rooted human teeth. Manufacturers’ recommendations were followed to operate each electronic apex locator to determine electronic length in the presence of 5.25% Sodium Hypochlorite, 2.625% Sodium Hypochlorite, 1.0% Sodium Hypochlorite, 0.9% NaCl, 2% lidocaine with 1:80,000 Epinephrine, and 2% Chlorhexidine. The difference between the electronic (EL) and actual length (AL) was calculated. In addition, EL measurements were classified into three categories: “correct” (AL±0.5mm), “long” (>0.5mm from AL), “short” (<−0.5mm from AL). There were no statistically significant differences in the accuracy of each of the three apex locators in the presence of the six endodontic solutions used in this study. The Root ZX mini and the Mini Apex Locator had similar accuracy to the Root ZX in the presence of each endodontic solution. It is concluded that the Root ZX mini and Mini Apex Locator have similar accuracy to the Root ZX and that the function of the three apex locators was not affected by the type of endodontic solution used.

Lipoid proteinosis: A case report with recurrent parotitis and intracranial calcifications

Asma’a Al-Ekrish, Ra’ed Al-Sadhan — 2011-12-05

Abstract: Lipoid proteinosis is an autosomal recessive disease of abnormal deposition of glycoprotein in various tissues. Symptoms may include a hoarse voice, lesions and scarring on the skin, easily damaged skin with poor wound healing, dry, wrinkly skin, and beading of the papules around the eyelids. Calcifications of brain tissue can lead to epilepsy and neuropsychiatric abnormalities. In this paper we will review the current literature on the disease and report a case of a 15year old Saudi female with lipoid proteinosis that presented initially with recurrent parotitis.

Correlation between cervical vertebrae morphology and chronological age in Saudi adolescents

Laila Baidas — 2011-12-16

Abstract: Cervical vertebrae morphology has been used as a biological indicator for assessing skeletal maturation in orthodontic patients, while chronologic age is considered a poor indicator of adolescent development. The objective of the study was to investigate the relationship between the chronologic age and maturation of cervical vertebra. The study sample was 214 patients (104 males and 110 females) in the age range of 7–17years (mean age 12.31±2.9). The Baccetti modified version of CVS (Stage I–VI) was used in the study. The cervical vertebral stages depend on morphological evaluation of three cervical vertebrae (C2, C3, and C4). The spearman rank correlation between chronologic age and cervical vertebral maturation stages was 0.864 (P<0.001). CVS method is more predictable than chronological age alone in the establishment of appropriate timing and types of orthodontic treatment.

Holdaway soft tissue cephalometric standards for Saudi adults

Sahar F. ALBarakati, Naif A. Bindayel — 2011-12-02

Abstract: The aim of this study was to report facial soft tissue cephalometric standards for a sample of Saudi adults and to compare them with the findings of other ethnic groups. Lateral cephalometric radiographs of 61 Saudi subjects (30 females and 31 males) with ages that ranged from 20 to 24years were selected. Subjects had Class I occlusal relationship with a balanced facial profile. Holdaway soft tissue analysis was then applied to measure two angular and nine linear parameters. The obtained findings were then compared to the Anatolian Turkish, Japanese, and Holdaway reported norms. Saudi sample showed a more convex skeletal profile (1.75mm±2.3) and prominent upper and lower lips. Nose prominence was found to be reduced (13.46mm±3.22) and the H angle was increased (15.16°±3.22). Saudi males were shown to have a more prominent upper lip and nose when compared with Saudi females (p<0.05). It has been concluded that Saudi standards for Holdaway soft tissue analysis were found to be statistically different from other ethnic group reported findings. Considering such standards for the studied population would aid in better diagnosis and treatment planning.

Fracture resistance of three post and core systems in endodontically treated teeth restored with all-ceramic crowns

2011-11-28

Abstract: The restoration of endodontically treated teeth requires the fabrication of a post and core to provide retention and support for the final crowns. The objective of this study was to compare the fracture resistance of endodontically treated teeth restored with glass fiber post and composite resin cores, customized zirconia posts, and cast metal post and cores. A total of 40 human extracted mandibular first premolars were used for the study. The teeth were randomly divided into four groups. Group A represented a control group that did not receive any posts and was filled with core material only; Group B comprised cast metal posts and cores; Group C comprised custom milled zirconia posts and cores; and Group D comprised glass fiber posts. All groups were prepared to receive all ceramic crowns. All samples were subjected to compressive testing with an Instron machine (Universal Testing Machine) and fracture loads and failure patterns were analyzed. The findings indicated a statistically significant difference between the failure loads in the groups studied. The mean load required to fracture the zirconia custom posts was higher (765.1±48.5N) than the fiber posts and the cast posts and cores (P<0.001). The fiber posts resisted a mean load of 561.4±37.2N which was higher than the cast posts and cores. The control group revealed the lowest value of fracture resistance. Within the limitations of this study, it can be concluded that customized zirconia posts and cores resisted a higher mean load (765.1+48.5) when compared with other post and core systems. Failure patterns within this group revealed catastrophic failure, but the failure loads were much higher than the average occlusal load.
