ABSTRACT
AIM: The aim of this study is to evaluate the prevalence and distribution of malocclusion among the coastal Andhra Pradesh population in south India. MATERIALS AND METHODS: The present study has a retrospective cross-sectional study design done on orthodontic records of patients who attended the Department of Orthodontics and Dentofacial Orthopedics at Lenora Institute of Dental Sciences and Hospital, Rajamahendravaram, India. Angle's classification and Dewey's modification were used to assess the distribution and pattern of malocclusion in patients. Statistical analysis was done using Chi-square test. RESULTS: The distribution of Angle's Class I malocclusion (67%) was more common than Angle's Class II malocclusion (30.1%) and Angle's Class III malocclusion (2.1%). The distribution of Class II division 1 was 23.2%, whereas Class II division 2 was 2.1% and Class II subdivision was 5.6%. Gender distribution according to Angle's classification exhibited a statistically significant difference (p-value < 0.001). Dewey's Class I type 2 was identified as maximum with 43.6% but no statistically significant gender distribution was reported. Conclusion: Angle's class I malocclusion was more prevalent with a distribution of 67%, followed by Class II malocclusion (30.1%) and Class III malocclusion (2.1%). A significant number of female patients were reported with Class I and Class II malocclusion whereas Class III malocclusion was predominately seen in males. It was noticed that, among all the malocclusions, Dewey's Class I type 2 was observed to be maximum but no significant gender distribution was observed.
ABSTRACT
OBJECTIVES: Treatment of dry mouth is the most common clinical challenge in the dental field. Although some remedies have been used to improve the signs and symptoms of xerostomia, none of them are absolutely satisfactory for the patients who have this alteration. In the current years, non-pharmacological treatments based on neuro-electro-stimulation for the treatment of xerostomia were developed. This review aimed at presenting recent developments for the treatment of xerostomia, applying neuro-electro-stimulation by miniaturized intraoral electrostimulators. MATERIALS AND METHODS: A thorough literature search between 1986 and 2018 was carried out using PubMed Central, Scopus, National Science Library, ProQuest, and Google Scholar databases; the results were reviewed, prioritized, and the findings were compiled. Twenty-two studies were evaluated for the review. RESULTS: This tool increases salivary secretion and improves xerostomia symptoms. Scientific trials have been carried out, which have revealed the wetting effect of the method described in this text. CONCLUSION: Neuro-electro-stimulation of the salivary gland plays an important role in the stimulation of saliva in patients who need further therapy and have poor quality of life. Intraoral electrostimulator offers a new non-pharmacological method for treating dry mouth.
