The prevalence of premature loss of primary teeth and its impact on malocclusion in the Eastern Province of Saudi Arabia.

OBJECTIVES: The present study was designed to determine the prevalence of premature loss of primary teeth and its effect on malocclusion in Eastern Province, Saudi Arabia. MATERIALS AND METHODS: This is an observational, cross-sectional study that included 307 male children aged 9-11 years old. Clinical examinations were performed using a disposable sharp explorer, a UNC periodontal probe and a dental mirror. The samples were examined clinically to detect the following traits: Angle's classification of malocclusion, overjet, overbite, anterior open-bite, lateral open-bite, midline shift and cross-bite. Additionally, a dental caries examination was performed using WHO methods. Questionnaires in Arabic were coded and sent to the students' parents. RESULTS: The mean DMFT was 5.61 (SD = 3.01). The d-component was the highest, with a mean of 4 (SD = 2.83). Of the 307 children, it was found that 204 (66.4%) had a high DMFT score, which is defined as a score above 4. It was found that 156/307 (51%) children had premature loss of deciduous teeth. CONCLUSION: A high prevalence of premature loss of teeth was found in this study. This finding emphasizes the importance of increasing awareness levels about this issue and focuses attention on the need for more preventive efforts to maintain healthy and normal dentitions that would improve the masticatory function and aesthetics of individuals and the whole population. In addition, the findings emphasize the importance of the early detection of premature loss of primary teeth to prevent future malocclusion.

Prevalence of oral conditions among methamphetamine users: NHANES 2009-2014.

OBJECTIVES: Methamphetamine (MA) is a widely used illicit drug and a nationwide public health concern. Although dental complications are consistently reported among MA users, yet limited nationally representative studies on the associations between MA use and oral health currently exist. METHODS: Using the National Health and Nutrition Examination Survey 2009-2014, we analyzed 8,762 respondents aged 30-64 years who had completed a periodontal examination. MA use was self-reported; periodontitis, untreated caries, and missing teeth were assessed by calibrated dentists. Descriptive statistics as well as multivariable regression analyses were performed. Data were weighted to yield representative estimates of the US adult population. RESULTS: Overall 7.8 percent of US adults aged ≥30 years had ever used MA. Ever-use prevalence was higher among males, whites, and individuals below the federal poverty level. Established MA users had a higher prevalence of untreated dental caries (36.6 percent), any periodontitis (54.8 percent), and severe periodontitis (12.2 percent) than those who had never used MA. The prevalence of any periodontitis was higher among current MA users (PR: 1.31; 95% CI: 1.05-1.62) than those who never used MA. Prevalence of untreated dental caries was higher among current MA users (PR: 1.53; 95% CI: 1.10-2.13) and established users (PR: 1.21; 95% CI: 1.02-1.48) than never users. Taking MA orally and/or through injection was associated with higher odds of severe periodontitis than orally only (AOR: 3.72; CI: 1.79-7.75). CONCLUSIONS: MA users had a higher prevalence of periodontitis and dental caries. Continued research assessing the relationship between MA use and oral health can inform clinical interventions and management of dental diseases in MA users.

Cocaine, polysubstance abuse, and oral health outcomes, NHANES 2009 to 2014.

BACKGROUND: Cocaine is the second most abused illicit drug in the United States. To date, no study has examined the association between cocaine use and oral health with a nationally representative sample. Our study examined the association between cocaine use-singly and with other substances-and oral health outcomes, including periodontitis and untreated caries, among US adults. METHODS: Data for 11,753 individuals, aged ≥30 years, who completed a periodontal examination, in the 2009 to 2014 National Health and Nutrition Examination Survey (NHANES) were analyzed. Descriptive analyses and multivariable binary logistic regression analyses were conducted on weighted data. RESULTS: Overall, 17% (20.5 million) of US adults aged ≥30 years had ever used cocaine, with higher likelihood seen among males, non-Hispanic whites, and those living in poverty. Current cocaine use prevalence was 2.6% (3.2 million). By number of co-used substances, the odds of having any periodontitis were higher among cocaine users who consumed ≥3 other substances (adjusted OR = 2.47; 95% CI = 1.15 to 5.30) when compared with solely cocaine users. By type of substance co-used, odds of having untreated caries were greater among those reporting cigarettes (adjusted OR = 1.94; 95% CI = 1.21 to 3.11) or methamphetamine (adjusted OR = 5.40; 95% CI = 1.92 to 15.14) usage. Odds of any periodontitis were higher among those reported ancillary cigarette use (adjusted OR = 2.84; 95% CI = 1.60 to 5.04) compared with cocaine-only users. CONCLUSIONS: In addition to a positive association between periodontal disease, dental caries, and cocaine use, select co-usage elevated the risk of oral disease. Patients should be screened for and counseled regarding substance abuse to facilitate a successful quit.

Regional Odontodysplasia Crossing the Midline.

Regional odontodysplasia is a non-hereditary development dental anomaly involving epithelial and mesenchymal-derived dental tissues. The condition affects both primary and permanent teeth. Clinically, affected teeth are hypoplastic, soft upon probing, have a yellow-brown discoloration and present high susceptibility to caries. Radiographically, the teeth show enlarged pulp chambers, open apices and no clear differentiation between enamel and dentin. The reduced radiopacity of the enamel and dentin gave rise to the term ghost teeth. We present the case of a three-year-old boy diagnosed with regional odontodysplasia involving more than one quadrant, showing facial asymmetry and missing primary and permanent teeth.

Radiographic Effectiveness of Resin Infiltration in Arresting Incipient Proximal Enamel Lesions in Primary Molars.

PURPOSE: The purpose of this split-mouth, randomized, prospective clinical trial was to evaluate radiographically the effectiveness of resin infiltration, as an adjunct to standard-of-care preventive measures compared to standard-of-care preventive measures alone, in arresting the progression of non-adjacent, incipient, proximal enamel lesions in primary molars 24 months after treatment. METHODS: The study included a total of 45 healthy five- to eight-year-olds who had been diagnosed radiographically with at least two non-adjacent, incipient, proximal enamel lesions in primary molars (90 lesions). Test group lesions were treated using resin infiltration followed by five percent topical sodium fluoride (NaF) application versus five percent NaF alone in the control group. The alpha level was set at 0.05. RESULTS: The children were examined after six, 12, 18, and 24 months. Twenty-five subjects were examined at the 24-month follow-up visit, At which time 10 of the 25 test lesions (40 percent) showed caries progression while 18 of the 25 control lesions (72 percent) showed caries progression (P=0.04). CONCLUSION: Resin infiltration as an adjunct to standard-of-care preventive measures is significantly more effective radiographically in reducing the progression of non-adjacent, incipient, proximal enamel lesions in primary molars compared with standard-of-care preventive measures alone after 24 months.
