Objective: To evaluate the effectiveness of “non-surgical periodontal therapy (NSPT)” on periodontal and renal parameters in periodontitis patients diagnosed with chronic kidney disease. Material and Methods: The review protocol has been registered in Prospero (CRD42020150938). Up to November 2019, we searched the PUBMED database without language constraints. We included randomized controlled (parallel-group or cross-over) trials with CKD and chronic periodontitis in adults aged 18 years and above. Three review authors independently assessed the studies. Three review writers gathered data and simultaneously assessed the risk of bias for individual trials using traditional Cochrane procedures. Results: Studies showed high variability. Three randomized clinical trials (RCT) were excluded because of high heterogeneity; meta-analysis could not be performed. Conclusion: Non-surgical periodontal therapy effectively improves periodontal and renal parameters. However, a meta-analysis could not be performed because of the high heterogeneity among the studies.

Objective: To evaluate and compare bite force (BF) in permanent first molars restored with glass ionomer cement (GIC), composite and amalgam, and normal contralateral permanent first molars. Material and Methods: BF was recorded in decayed permanent first molars, which were filled with GIC (n=30), composite (n=30), and amalgam (n=30), and in healthy contralateral first molars (n=90) with Force Transducer Occlusal Force Meter and compared. Results: BF was significantly higher in normal teeth on the contralateral side compared to teeth restored with GIC and composite. However, in patients with amalgam restoration, though it was less compared to that on the contralateral side, it was not statistically significant (p>0.05). Conclusion: Restoring teeth with various filling materials may improve bite force. In the present study, it was found that the teeth restored with amalgam had higher bite forces in comparison to the other restorative materials used. However, it was not comparable to that observed in the normal tooth (control) on the contralateral side.

Objective: To assess the prevalence of tooth decay and it’s associated factors among the age group of 15-20 years old visiting Ayder Comprehensive Specialized Hospital. Material and Methods: An epidemiological cross-sectional descriptive study was conducted among 384 subjects aged 15-20 years. A closed-ended questionnaire, according to the World Health Organization methodology was used to collect the data. The subjects were examined for the presence of tooth decay using the DMFT Index. One examiner was trained and standardized using a Kappa test (K=0.90). To test the differences in the DMF-T index related to socioeconomic variables, the Chi-square and the Mann-Whitney tests were employed. For all tests, the level of significance was set at p≤0.05 with 95% Confidence level. Results: The magnitude of tooth decay among study participants was 57.8%. The mean decayed, missed and filled was 1.26 and prevalence was higher in males (34.1%). Poor oral hygiene practice was strongly associated factor with tooth decay. 56.2% of visitors from the urban area were mainly affected by tooth decay. Conclusion: Tooth decay is highly prevalent among visitors between15-20 years of age. Tooth brushing habit, residency, and consumption of sugary food and drinks were significantly associated with the occurrence of tooth decay. Early diagnosis and prompt treatment can prevent further damage.

Objective: To assess the knowledge, attitudes, and practice regarding oral health care among parents of autistic children and also the challenges faced by them in providing dental care for their Autism Spectrum Disorders (ASD) children’s in four regions of Kingdom of Saudi Arabia. Material and Methods: In total, 263 parents of autistic children participated in this cross-sectional study who were enrolled from 4 major regions of Kingdom of Saudi Arabia. A self-administered questionnaire formulated in simple Arabic was distributed to parents of children diagnosed with autism or any form of ASD. The questionnaires consisted of demographic questions and also to assess their knowledge on oral health, child’s oral hygiene practices and visits to their dentist, oral hygiene, experience and challenges in waiting room area before the dental treatment, acceptance of treatment or rejection, accessibility to find non-dental centers either government or private for treatment and their recommendations. Results: All the parents brushed their child’s teeth using a toothbrush and fluoridated toothpaste. A total of 29.7% of the parents informed that their child never brushes teeth. A total of 41.4% of the parents visit the dental clinic when the child complains about dental problems and 54% find difficulty in locating appropriate dental clinic to deal with their ASD children. Most parents reported taking their child to a private office (38.8%). Only 3.8% of parents reported that their children had seizures during dental procedures. Conclusion: The knowledge toward oral health was found to be inadequate among the majority of the parents. Parents of ASD children need to be educated about the consequences of oral health neglect and the importance of regular check-ups.

Objective: To evaluate the prevalence and gender-wise distribution of peg-shaped maxillary permanent lateral incisors among populations in Saudi Arabia representing different geographical locations (Saudi, Jordan, Egypt, Syria, Philippine, Pakistan, India and Bangladesh). Material and Methods: Panoramic radiographs of 9945 patients attending outpatient university dental clinics of College of Dentistry, Jouf University, Saudi Arabia between February 2014 and January 2018 were collected from the archives randomly. Two calibrated investigators examined the data, which were collected from the dental radiology department archives with prior permission from the authorities. The anomalies of maxillary lateral incisors (right and left) were investigated. Results: Among all geographic locations, the prevalence of peg laterals was more in males in comparison to females except in Pakistani and Philippine populations. Among the Saudi population, peg laterals' prevalence was more in case of right lateral incisor than the left incisor. Conclusion: A higher prevalence of peg laterals was found in Saudi. Conclusion: A higher prevalence of peg laterals was found in Saudi region, followed by Egypt. Among all geographic locations, the prevalence of peg laterals was higher in males than females except for Pakistan and Philippines populations. Among Saudi population prevalence of peg laterals was found to be higher in case of right lateral incisor when compared to the left.
