ABSTRACT

INTRODUCTION: The accurate diagnosis of vertical skeletal abnormalities presents several challenges. Specific cephalometric parameters can be effectively used for this purpose; however, their diagnostic utility has not been fully ascertained. This study examined the effectiveness of two novel cephalometric parameters in diagnosing vertical dysplasia. METHODS: Orthodontic patients were divided into three study groups: average growth group (AGG), horizontal growth group (HGG), and vertical growth group (VGG). The efficacies of the sum of the angles (maxillary, mandibular, and ramal) and the height ratio (lower anterior facial height [LAFH]/upper anterior facial height [UAFH]) in identifying the different growth patterns were examined. Receiver operating characteristic curves were used to quantitatively assess diagnostic precision. RESULTS: A total of 150 patients were included and divided equally among the 3 study groups. The ramal and mandibular angles varied across AGG, HGG, and VGG; however, the maxillary angle and the sum of these three angles did not vary significantly. There was a significant difference in LAFH, UAFH, and their ratios among the three groups. The height ratio had a sensitivity of 88% and 92% for the diagnosis of VGG and HGG, respectively, with cutoff values of 46 and 34, respectively (P < 0.001). CONCLUSIONS: The height ratio values varied considerably according to facial growth patterns, suggesting its utility as a diagnostic tool for skeletal dysplasia with greater reliability for positive treatment outcomes.

ABSTRACT

Background. An accurate diagnosis of vertical skeletal abnormalities presents several challenges. Specific cephalometric parameters can be effectively used for this purpose; however, the diagnostic accuracy of these parameters has not been entirely ascertained. This study examines the effectiveness of two novel cephalometric parameters for diagnosing vertical dysplasia. Methods. In this retrospective study, orthodontic patients were distributed into three study groups: average growth (AGG), horizontal growth (HGG), and vertical growth (VGG). The efficacies of the sum of angles (maxillary, mandibular, and ramal) and the height ratio (lower anterior facial height [LAFH]/upper anterior facial height [UAFH]) in identifying different growth patterns were examined. Receiver operating characteristic (ROC) curves were employed to assess the diagnostic precision quantitatively. Results. A total of 150 patients were included and divided equally among the three study groups. The ramal and mandibular angles varied across AGG, HGG, and VGG; however, the maxillary angle and the sum of these three angles did not vary significantly. There was a substantial variance in LAHF, UAHF, and their ratio in the three groups. The height ratio had 88% and 92% sensitivity to diagnose VGG and HGG, with cut-off values of 46 and 34, respectively (P<0.001). Conclusion. Height ratio values varied considerably depending on the facial growth patterns, suggesting its efficacy as a diagnostic tool for skeletal dysplasia, with greater reliability for positive treatment outcomes.

ABSTRACT

According to the new classification proposed by the recent 2017 World Workshop on Periodontal and Peri-implant Diseases and Conditions, periodontitis, necrotizing periodontal diseases, periodontitis as a manifestation of systemic diseases, and systemic diseases or conditions affecting the periodontal supporting tissues, are considered as separate entities. Scientific evidence has demonstrated that periodontal diseases are not just simple bacterial infections but rather complex diseases of multifactorial complexity that interplay with the subgingival microbes, the host immune, and inflammatory responses. Despite dental plaque biofilm being considered the primary risk factor for periodontitis in the vast majority of patients that dentists encounter on a daily basis, there are other factors that can also contribute and/or accelerate pathologic progressive attachment loss. In this article, the authors aim to briefly review and discuss the present evidence regarding the association between periodontal diseases and systemic diseases and conditions.

ABSTRACT

BACKGROUND: Scaling and root planning (SRP) is the gold standard approach for treatment of chronic periodontitis but used alone it may not be effective in removing periodontal pathogens from sites where access is poor. OBJECTIVE: To evaluate and compare the clinical and microbiological efficacy of ozone and chlorhexidine (CHX) as an adjunct to SRP in patients with chronic periodontitis. METHODS: Twenty-five patients with generalized moderate to severe chronic periodontitis with presence of at least one site in each quadrant with a probing depth ≥5 mm were recruited. In a split mouth study design, two quadrants were randomly allocated to the SRP and ozone therapy and the remaining two quadrants to SRP and CHX therapy. Plaque index (PI), Gingival index (GI), probing depth (PD), clinical attachment loss (CAL) were assessed. Subgingival plaque samples were obtained for assessment of Aggregatibacter actinomycetemcomitans (Aa) and Porphyromonas gingivalis (Pg). RESULTS: Both groups demonstrated significant intragroup reduction in PI, GI, PD, CAL, Pg count and Aa count from baseline to 3 months follow-up. There were no significant differences between two groups for any of the parameters. CONCLUSION: Ozonated olive oil can be used as an adjunctive subgingival irrigant in patients with chronic periodontitis.

ABSTRACT

The aim of this split-mouth, randomized controlled clinical trial was to evaluate the efficacy of low-level laser therapy (LLLT) and photodynamic therapy (PDT) as an adjunct to scaling and root planing (SRP) in treatment of chronic periodontitis. Each quadrant was categorized into control group (SRP alone; two quadrants per patient), test group 1 (SRP + PDT), and test group 2 (SRP + LLLT. The test groups showed significantly higher reductions in Gingival Index, probing depth, and clinical attachment level as well as reductions in Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans counts at 1-, 3-, 6-, and 9-month follow-ups when compared with the control group.
